Estimates for maintenance and renovation
維修裝修估算

1. Estimates for maintenance and renovation may place greater emphasis on classification by locations. It is not appropriate to classify items under them according to so many elements used for new works, but structured levels are still necessary to facilitate easier reading and understanding. Therefore, the items can be grouped and listed as follows (the locations may be classified before or after them but should not be too trivial):
   維修裝修估算項目比較著重按地方分類,之下不宜再如新建工程的分部分得那麼多,但又要有層次,便於閱讀理解,故可分類排列如下(地方可先分或後分但不宜太瑣碎)：

Measurement of quantities
計量

1. Do not rely too much on on-screen measurement of cad or pdf files because there is no record of what have been measured and no detailed breakdown

   確保規定工程一切險及第三者責任險的條款的聯名被保險人的名單齊全;除發包方丶承包方及各層分包方外,還要注意是否要加入:
   • the Building Manager (being a manager of the relevant properties, he may be held liable)
     物業管理人(因他為相關物業的管理人,可能被追討責任)
   • other contractors employed by the Employer (because their works will be carried out currently with the Works, and the liability for accident may not be clearly separable)
     發包方聘用的其他承包商(因其工程與本工程同時執行,意外責任未必能分得清)
   • consultants (because they are not directly performing the Works, and the insurances can only cover risks caused by the performance of the Works, therefore, it is doubtful whether they should be included as one of the joint-insured) 
     顧問(因他們不是直接執行工程者,而保險只保障執行工程所造成的風險,因此,把他們作為聯名被保險人之一的效用存疑)
2. Adjust the old term “separate specialist contractor” to match the term used in the new Standard Forms of Contract
   調整“separate specialist contractor”這舊有叫法以符合新標準合同的叫法

6. State the values of the previous works such as foundations and hoardings for inclusion as part of the sum insured under the material damage section to ensure full cover; alternatively, if the risk of total loss is low, insure as the principal’s properties under the third party liability section, but the limit of indemnity will be lower
   列出之前的工程，例如基礎、圍街板等的價值，加入物質損壞保險的保險額內以取得全額保；或者，如全毀的風險低,可以作為工程委託方的財産形式在第三者保險部份受保,但賠償額較低

Preparing Bills of Quantities or Schedule of Rates
編寫工程量清單或單價表

1. Read the Standard Method of Measurement, whether you are experienced or not; do not just listen to other people

   計混凝土工程時要注意混凝土的標號、樑深的層級、高度的層級、邊沿、接肩、直斜彎，等等！
3. Do not blindly follow past Bills of Quantities or Schedule of Rates because they may have simplified the measurement which may not be applicable to every project, and may in fact be wrong

Tender clarification queries
詢標問卷

• Clarify in the tender clarification queries only those incorrectly priced high or low rates, not comparatively high or low rates
  在詢標問卷應只問錯誤地高或低的單價,而不是相對高或低的單價

Financial reports
最終造價估算報告

1. Estimated Amount = Reasonably estimated maximum amount for budgetary purposes
   估計價 = 合理估計的最大金額，供投資預算用
2. First Claimed Amount = Amount initially claimed or the biggest amount claimed by the Contractor
   原報價 = 承包商第一次或最大的一次的報價
3. Latest Claimed Amount = Latest revised amount claimed by the Contractor, or the current amount after negotiated reduction
   最新報價 = 承包商最新的修訂報價，或通過談判應已減低了的金額
4. Assessed Amount = Amount accurately or roughly assessed to be comfortably payable finally, in other words, the minimum final amount payable
   審核價 = 經準確或大約計算得的可安心作為最終應付的總額，亦即等如最低的最終應付總額
5. When Assessed Amount = Claimed Amount, Estimated Amount should also be = Assessed Amount
   當審核價 = 報價時，估計價亦應 = 審核價
6. In the final stage of final account, the Estimated Amount should be smaller than the Claimed Amount
   到結算後期，估計價應低於報價

Approximately
大約

• Write “approximately X Nos.” instead of  “approximate X Nos.”
  寫成“approximately X Nos.” 而不是  “approximate X Nos.”

Replace by or with
更換

• “replace by” or ”with” may be distinguished by this example: in “replace A by B with C”, A is the replaced, B is the one who takes action, and C is the substitution
  “replace by”定”with” 可以此例子分辨：”replace A by B with C” 中A是被更換者、B 是行動者、C是代替者

Final account item descriptions
結算項目說明

1. Note that if the words "revise", "change", "replace" and similar are used in the final account item descriptions, cost omission and addition are both expected
   注意當”修改”、”改變”、”更換”等類似用詞在結算項目說明使用時，意味應同時有減帳及加帳
2. Make sure that the final account item descriptions are consistent with the cost effects
   確保結算項目說明是與費用影響匹配

4. Split them into several emails if the file size is too large.

Emails attached to emails

1. Save emails attached to an email received on to the computer desktop and move them back to the email folder. They will appear at the positions of their original email dates. This would enable reading the story in a chronological order, and easy tracing later.
2. Print such emails like other emails.

Handling of printed emails

1. When there are more than one attachment, identify whether they belong to one submission or several submissions each bearing its own serial number or date (e.g., letters, site memos, proposed variations, instructions, variation quotations, payments, minutes, regular reports, etc.).
2. Separate between different submissions by staples or clips.
3. Arrange different submissions according to the dates stated on them (not the dates received).
4. Within the same submission, arrange the attachments in logical sequence, usually covering letter or site memo at the front and drawings at the back. Descriptive documents are usually in the middle. Summaries may be put before or after the details depending on the authors. Follow the specific contents page or the list of items stated in the email. Do not follow the order of the attachments to the email because they have no logical sequence.
5. Fold thin A3 attachment (say, not exceeding 5 pages) forward from right to left along the centre line into A4 size, and then fold the top flap from left to right along the centre line into half A4 size. 
6. Fold thick A3 attachment backward from right to left keeping the edge clear from the left punch holes.
7. Stamp the date received on the top right hand corner of each separate submission received (but no need for different parts of the same submission which are not supposed to be taken out for use separately).
8. Stamp the date received on the top right hand corner on each programme and on the bottom right hand corner on each drawing because they may be filed or taken out for use separately.
9. Mark near the date chop the relevant instruction numbers.
10. Stamp neatly and clearly at a blank space.
11. Do not stamp on submissions emailed by our office unless they are returned with emails received.
12. Write on the emails simple reference numbers and dates of those separate submissions which are filed not immediately after the relevant emails to enable future tracing.
13. Initial neatly on the bottom left corners of the emails after arranging the emails and attachments.
14. File the emails directly in the appropriate email sub-folders of the relevant projects.
15. If the emails are printed by somebody other than the relevant team members, file the emails under the "00Printed" email folder for subsequent filing by the relevant team members. 
16. Distribute the printed emails once every half-an-hour to the relevant project team members for reading.
17. Circulate within the relevant team starting from the director to the assistant. If any person is absent, pass on to the next one present.
18. Read and initial on the top right hand corners of the emails and the first pages of separate submissions.
19. Take immediate actions as required by the emails.
20. File the emails in the relevant hardcopy folder after all team members have read and initialled and when no further immediate action is required.
21. File different submissions according to their dates even though those dates may be sometime in the past so that they can tell the complete story when the files are read sequentially sometime later. The date received stamp can help to trace that emails sending them though the submission and the email may be filed separately.​​​​​​

​​ Filing of letters and emails 信件和電郵的歸檔

1. Create a separate folder section for each preliminary cost estimate, proposed instruction, confirmation of verbal instruction, formal instruction, other item to appear in the final account (e.g., group of provisional quantities, provisional sum), financial report, payment valuation, etc.
2. Name the email folders or label the hardcopy folder flysheets by their serial numbers.
3. If an email covers more than one folder section, email it back to the office with a note added to the subject so as to distinguish. Do not just make copies because identical copies will be deleted if a "remove duplicate" check is done.
4. File requests for estimates and estimates under the proposed instruction folders. Move them to the formal instruction folders after the issuance of the formal instructions.
5. Move confirmations of verbal instructions to the formal instruction folders after the issuance of the formal instructions.
6. Change the folder or label names to reflect or track the move.
7. File quotations and assessment related to a formal instruction under the same folder section, i.e., all matters related from cost estimate until agreement are to be filed together to tell the complete story.
8. Spilt into more folders if an instruction covers more than one variation or final account item.
9. Update the financial report descriptions and amounts to match whenever a new or revised quotation or assessment is received or issued.
10. File communications with each tenderer separately. This is important for tracking the development, preparing the letter of award/intent, and contract binding.
11. In principle, all incoming and outgoing documents in the email folders and hard copy folders should mirror each other, except for working documents not sent out.
12. Bind tender documents as a book, not to be filed.

• Measure quantities for approximate cost estimates, bills of quantities, variations, and remeasurement.
• Get to know the Standard Method of Measurement better throughout the process.
• Get to know the geometric forms and names of the components making up the whole construction.
• Draft bills of quantities for editing by the senior.
• Participate in counter-checking the measurement done by team members.
• Assist in monthly valuation of contractors’ payments.
• Visit the site for the purposes of doing the valuation.
• Assist in preparing monthly financial reports.
• Accompany the senior to attend pre-contract design meeting or post contract site meetings.
• Price the variations and remeasurement.
• Price the approximate cost estimates and the bills of quantities.
• Agree final accounts with the contractors.
• Assist to prepare the comparison tables attached to tender reports.

Personal Attributes

• Fair and reasonable – While Consultant Quantity Surveyors are engaged by their clients to protect the clients’ interest under the construction contract, they also have a duty under the construction contracts to act fairly and reasonably. Being fair and reasonable can in fact avoid unnecessary disputes under the construction contracts.
• Integrity – Quantity Surveyors are dealing with money though no money is actually passing through him. However, any corruptive act would mean a huge sum of money lost by the clients or contractor-employers. Quantity Surveyors must serve with the highest degree of integrity.
• Patience and persistence – Quantity Surveyors need to spend a long period of time to measure the quantities required for bills of quantities time and again. This would need patience and persistence to the task. Quantity Surveyors have to negotiate with contractors over contractual and monetary claims. Differences in opinions can lead to heated arguments. Patience is again very important.
• Attention to details – Quantity Surveyors must be accurate in his words and cost figures. Great attention to details to ensure error free is a must. Self-checking and cross-checking are both essential.

(updated, 18/2/2023)

Core Skill-sets Required

• Construction technology - Good knowledge of construction technology is the foundation stone of any surveyors.
• Building services – While traditionally cost management of building services is handled by the building services engineers, for over 3 decades in Hong Kong Quantity Surveyors have already been providing measurement and cost management services for building services. Therefore a good knowledge of building services is also required.
• Mathematics – Daily life mathematics is enough. Use of calculus is rare.
• 3-D visualization – Quantity Surveyors should be able to visualize the 3-dimensional geometry based on 2-dimensional drawings.
• Measurement – Good measurement knowledge and skill are the next higher level of foundation stone of Quantity Surveyors.
• Language – Quantity Surveyors have to read many documents ranging from Standard Method of Measurement, Specifications, Forms of Contract, legal textbooks, occasionally case laws, insurance policies and bonds. Quantity Surveyors have to draft terms and conditions into the tender documents for construction contracts and loopholes must be avoided. Consultant Quantity Surveyors have to write to advise their clients and other members of the consultant teams. Contractors’ Quantity Surveyors must also be able to write properly to put forward the Contractors’ case. The language skills of Quantity Surveyors must be high in order to rise up the career ladder.
• Use of computers and software – Quantity Surveyors have to know how to use the usual office automation software with proficiency.
• Site visit – Quantity Surveyors should like to go to site periodically.

(updated, 18/2/2023)

Valued Added Skill-sets

• Building Information Modelling – This is an important technology which must be learned and used by the present-day construction related professionals. Some Quantity Surveyors have developed special interest to realise the potential of BIM for Quantity Surveyors.
• Software programming skills – While the majority of Quantity Surveyors do not have the need and therefore the aptitude to possess software programming skills, better use of BIM requires the knowledge to write scripts or programmes.
• Digital transformation – Transforming and running the business work flow and deliverables in digital mode are the upcoming trend of all business sectors. Quantity Surveyors cannot fall behind.
• Carbon emission reduction – Calculating carbon emissions and formulating carbon emission reduction measures will be the required upcoming skills of Quantity Surveyors.

(updated, 18/2/2023)

Types of Projects Involved

• Public sector works and private sector works
• Building and civil engineering works
• New build, maintenance, alterations and additions, and renovation

Employment

• Good Quantity Surveyors are always in good demand both by consultant quantity surveying practices and contractors and even big sub-contractors.
• When the economy is booming with many new-build projects, Quantity Surveyors have to work a lot of overtime throughout the year. However, working overtime is common amongst the construction related professionals. The extent of overtime worked by Quantity Surveyors is not the worst as compared to other professions.
• When the economy is bad, new-build projects will be less but people would spend money in maintenance, alterations and additions, and renovation. Final accounts for completed new-build projects are still to be settled. These offer a cushioning effect over the possible redundancy of Quantity Surveyors. Over the years with many recessions, Quantity Surveyors are less hard hit as compared with other construction related professionals.
• Quantity Surveyors working for contractors will have higher pay.
• Quantity Surveying graduates tend to choose to work for consultant quantity surveying practices first at a lower pay in order to gain training experience for the Assessment of Professional Competence. After getting qualified, they would have more choices.
• In good times, consultant quantity surveying practices offer overtime pay. In the best time (not in recent years), the basic salary can become doubled.
• Qualified Quantity Surveyors working for Government are on the same pay scale as other construction related professionals.

Where is the satisfaction?

• Winning the trust of clients, being consulted frequently.
• Problems solved.
• Proper monitoring of prices, without unpleasant surprises to the clients.
• Moving projects ahead to get through tendering.
• Considered fair and reasonable by both the clients and the contractors.
• Seeing projects constructed successfully.
• Closing final accounts to all parties’ satisfaction.

Budgets, cost estimates and cost plans

1. Budget:
   • A budget is the maximum sum a Developer is willing and able to spend on a project.
2. Cost estimate:
   • A cost estimate is a forecast of the probable ultimate cost based on the current design.
   • It is required to be done throughout the pre-construction stages as well as the construction stage until the estimated costs become fixed prices.
   • A cost estimate for now, if satisfactory and approved, will become the cost plan for the future design.
3. Cost plan:
   • A cost plan is a detailed cost framework for controlling future design.
   • It sets out the portions of the total budget allocated to different parts of the construction so as to serve as the cost limits to the relevant parts of the construction.
   • It may just be based on some interpolation from the cost data of other projects or may be based on some detailed cost estimate specifically prepared for the relevant design.
   • It usually refers to the cost plan before the award of the principal contract. After that, the cost plan will be replaced with regular final statements.
4. Rough indication of costs ("RIC"):
   • It is a kind of cost estimates. It may be just based on unit cost / number or unit cost / floor area or unit cost / other functional unit to be used in the feasibility study or early design stage based on some ideas or sketch designs
   • HK ArchSD still calls it "Rough Indication of Costs" when the estimate is still in the early stage though the details may be more than just based on unit cost per floor areas.
5. Approximate estimate:
   • Approximate estimates should be done using expedient methods, approximations and shortcuts to reduce estimating time and costs in order to afford more estimates.
   • This principle should be applied to pre-construction cost estimates or post contract cost estimates.
6. Detailed cost estimate:
   • It is a more detailed cost estimate prepared when the design is more developed.
   • "Detailed" refers to the number of items measured, rather than to the accuracies of the quantities estimated.
   • Some consultants call it "Preliminary Cost Estimate", and some call it "Cost Plan".
   • It may become the Budgetary Estimate if approved.
7. Pre-tender estimate (按工程量清單計算標底):
   • A pre-tender estimate is no longer an approximate estimate and is prepared by pricing the bills of quantities ready for issuance or already issued for tendering.
8. A logical sequence is like this:
   • Rough Indication of Costs => Detailed Cost Estimate => Cost Plan / Budgetary Estimate => Pre-tender Estimate.

Elemental cost classifications

1. Trade by trade classifications:
   • Pricing documents for tendering are usually arranged in trade by trade or works section orders or work breakdown structures according to the local standard method of measurement or local practice.
2. Elemental cost classifications:
   • Instead of following the same order, pre-construction cost estimating in many countries (not all) adopt an elemental cost classification, which divides the costs of a construction project into various parts ("elements") each serving a specific function or common purpose such that the costs of alternatives serving the same function or purpose can be compared, evaluated and selected irrespective of their trades, works sections, design, specification, materials or construction.
3. Classifying the costs of a building (or other construction) into elements would facilitate:​
   • Comparison of the costs of different design options serving the same elemental function
   • Comparison with costs of other projects by elements
   • Rationalizing the budget allocation between different elements for better use
   • Quicker estimating based on elemental quantities which are easier to measure
   • Analysis of data for different projects on the same basis and classification.
4. Different elemental cost classifications in Hong Kong:
   • Different QS practices and ArchSD have different elemental classifications.
   • ArchSD adopts the following Project Element Cost Model as described in the Standard Method of Measurement for Building Elements 2020 Edition published by the Architectural Services Department (https://www.archsd.gov.hk/media/publications-publicity/schedule-of-rates/asdsmmbe_2020.pdf):
     • 
5. Many other places outside Hong Kong also have their own elemental cost classification systems, e.g.:
   • UK's Uniclass:
     • https://en.wikipedia.org/wiki/Uniclass#The_tables
     • https://www.thenbs.com/our-tools/uniclass-2015#classificationtables(browse the Element / Function table)
   • UK RICS's NRM 1 ("New Rules of Measurement 1: Order of cost estimating and cost planning for capital building works"):
     • https://www.rics.org/uk/upholding-professional-standards/sector-standards/construction/rics-nrm-new-rules-of-measurement/
   • USA's Omniclass:
     • https://www.csiresources.org/standards/omniclass (incorporating MasterFormat for Work Results and UnitFormat for Elements)
   • Australia, Canada, Malaysia, Nigeria, etc.
6. ICMS:
   • International Cost Management Standard (ICMS) (https://icms-coalition.org/the-standard/) is a global classification and reporting standard covering the life cycle costs and carbon emissions of building and civil engineering projects. "elements" is called “Groups” and “Sub-Groups” in ICMS 3 so that they are equally applicable to costs and carbon emissions. The examples shown here are based on that standard. See also https://kctang.com.hk/web/international-cost-management-standard.

Construction floor area and gross floor area in Hong Kong

1. Different areas:
   • For costing, leasing and sales of buildings and related land, people usually have to refer to unit cost or price per floor area of the buildings as the most important controlling parameter.
   • However, there are many types of floor areas being defined for different purposes in Hong Kong or other places outside Hong Kong. An understanding of their possible differences is important.
2. CFA:
   • Quantity Surveyors measure the construction floor area (CFA) in order to estimate the total construction cost of a building.
3. GFA:
   • Lands leased by the Government in Hong Kong are subject to limitation on the gross floor areas (lease GFA) of the buildings which may be built on the land. Some of the construction floor area is not accountable for the lease GFA. The Lands Department is responsible for the control. Read the Lands Department's Practice Note on Accountable and Non-Accountable GFA under Lease at https://www.landsd.gov.hk/en/images/doc/1998_1A_text.pdf.
   • Building plans have to be submitted to the Buildings Department for approval and consent before construction. The gross floor areas (GFA) are also controlled by the Buildings Regulations. Read the Buildings Department's Practice Note on Calculation of Gross Floor Area and Non-accountable Gross Floor Area at https://www.bd.gov.hk/doc/en/resources/codes-and-references/practice-notes-and-circular-letters/pnap/APP/APP002.pdf.
   • The Lands Department's Practice Note says while the Lands Department is usually prepared to follow the Buildings Department's ruling in exemptions from GFA calculations, it reserves its right and absolute discretion to do otherwise in individual cases.
4. Saleable area:
   • There are further complications due to the use of saleable area for residential properties. See Cap. 621 Residential Properties (First-hand Sales) Ordinance at https://www.elegislation.gov.hk/hk/cap621.

International Property Measurement Standards (IPMS)

1. The International Property Measurement Standards at https://ipmsc.org/standards/ are intended to unify the rules of measurement of various kinds of floor areas for different types of buildings.
2. A single harmonised standard covering All Buildings has been published on 15 January 2023 to supersede all previously published standards for individual asset classes.
3. IPMS 1 (gross external floor area) and IPMS 2 (gross internal floor area) are referred to by ICMS.
4. Read this and appreciate the diagrammatic illustration.
5. CFA in Hong Kong is close to IPMS 1 with one exception: accessible rooftop terraces are included in IPMS 1 but not in Hong Kong CFA.

Need for historical cost analyses

1. Before talking about the cost estimates, it may be appropriate to talk about cost analyses first.
2. Cost analyses are needed to:
   • Benchmark new projects
   • Provide cost data for new estimates
   • Provide cost parameters for new estimates​​​​​​​.

(revised, 18/2/2023)

Cost analyses

Example adopting ICMS

​​​​​​​​​​​​​​

(image updated, 5/3/2023)

Classify total costs

1. A cost analysis analyses the awarded or final prices of a project and re-classify the costs following the same classification used for the cost estimates or cost plans.
2. When classified in elemental format, the cost of each element or sub-element is summed up into a single line item.
3. The cost is called “elemental cost” in Hong Kong.

Identify elemental quantities

1. A single representative quantity is measured for that line item.
2. The single quantity is called "elemental quantity" in Hong Kong. “representative” means that the quantity can best represent the cost changes in case of quantity changes.

Get elemental unit rates

1. The cost of that cost item is then divided by the elemental quantity to give a single all-inclusive rate.
2. The single all-inclusive rate is called "elemental unit rate" in Hong Kong.
3. That means:
   • elemental cost / elemental quantity = elemental unit rate,
   • or
   • elemental quantity x elemental unit cost = element cost,
   • depending on the order of presenting the columns in table form.
4. The elemental unit rates are very useful when the cost of a new project is required to be estimated before any detailed design is available.

Apply the elemental unit rates to new projects

1. Elemental quantities can be measured for the new project and priced at elemental unit rates of the reference projects.
2. There are not too many items of elemental quantities to be measured. The cost estimating process can therefore be very fast.
3. Of course, the elemental unit rates may not be directly applicable to the new project.
4. It should at least be adjusted for the changes in the price levels from the times it was applicable to the reference project to the time of the new project, and then for other changed factors.

Get quantity ratios or factors

1. A cost analysis should also contains quantity ratios or factors such as:
   • elevation area : floor area
   • concrete volume per floor area
   • formwork area per concrete volume or floor area
   • rebar weight per concrete volume or floor area
   • etc.
2. These quantity ratios can serve as useful references when estimating the costs of new projects.
3. Apart from using the data in a cost analysis to estimate the cost of a new project in the absence of detailed design, the data can also be used to benchmark the cost of a new project after a more detailed cost estimate is done to ensure that the new project would not go out of order.
4. Hong Kong Government uses this technique to control the costs of new project at the design stage.
5. The Architectural Services Department has published a very detailed Project Cost Analysis Form.

Changes in cost and price levels

1. Due to changes in the market conditions, the unit rates for exactly the same description of work may change over time.
2. The market conditions may include fluctuations in the costs of labour, materials and plant, market competition, and other factors.
3. Unit rates applicable in the past would need to be adjusted to the current level.
4. Tender price or cost indices are therefore prepared to provide the adjustment factors.
5. Their differences should be appreciated.
6. Tender price indices and cost indices can fluctuate at different rates because price = cost + profit, and the price may increase less than the cost increase in order to secure projects or may increase more in case the market is full.

Different methods of approximate cost estimating 計算概算的方法

Different methods

1. Unit method (common).
2. Superficial method or area method (common).
3. Cubic method (seldom used for buildings).
4. Storey enclosure method (seldom used now).
5. Elemental cost estimates (common):
   • Elemental quantity method
   • Approximate quantity method.
6. Condensed elemental method using the most significant cost parameters.

Pre-tender estimate:

1. A pre-tender estimate is no longer an approximate cost estimate and is prepared by pricing the bills of quantities ready for issuance or already issued for tendering.

Unit method (按功能單元個數計算)

1. The estimated cost of a building is calculated based on the number of functional units provided by the building x unit cost per functional unit.
2. ICMS has suggested the following functional units for buildings: number of occupants | number of bedrooms | number of hospital beds | number of hotel rooms | number of car parking spaces | number of classrooms | number of students | number of passengers | number of boarding gates.
3. The unit method is a crude method serving as an early indication of the probable order of cost of the average building of the relevant type.
4. It is not useful for forecasting with a high degree of accuracy the costs of newly proposed buildings of the same type because their designs can be very different.
5. However, it may be used by clients and in particular government departments to serve as a cost yardstick controlling the budget of newly proposed projects.
6. It is still also useful to serve a check that a unit cost per floor area may sound reasonable but, when expressed in unit cost per functional unit, the unit cost can be out of order because of excessive floor area per functional unit.

Superficial method or area method (按樓面積計算)

1. The estimated cost of a building is calculated based on the floor area of the building x unit cost per floor area.
2. This is the most commonly used method, possibly because the sales and rental prices are also expressed in unit cost per floor area.
3. Note however that there are many definitions of "floor area". The same definition should be consistently applied.

Cubic method (seldom used for buildings) (按樓體積計算(現少用))

1. The estimated cost of a building is calculated based on the volume of the building x unit cost per volume.
2. In theory, the volume can take care of the different storey heights of the building.
3. This is not commonly used probably because the floor areas are more readily available, and calculating the volumes would mean a further step to be done.
4. The cubic method may be useful for site formation works or civil engineering works involving massive volume of work.

​​​​​​​Storey enclosure method (seldom used now) (按樓板及外殼面積加權計算(現少用)

1. In essence, the estimated cost of a building is calculated based on the total of the weighted areas of bottom slabs (basement or ground), suspended floor slabs, roof slabs, and walls below and above ground x unit cost per total weighted area.
2. Each type of slabs or walls are given different fixed weightings to reflect their relative ratios of costs.
3. The calculation is much more complicated than the superficial method or the cubic method.
4. With so many varieties of construction components and materials, whether the fixed weightings can truly reflect the relative ratios of costs is doubtful.
5. This method is seldom used these days.
6. Search the internet for details and examples.

(revised, 18/2/2023)

Elemental quantity method (按功能分部工程量計算)

1. The building cost is classified into different elements (or Groups or Sub-Groups as used in ICMS as shown under the "Sections" column in the example below which follows ICMS classifications).
2. Each element is represented by an appropriate elemental quantity which best represents the elemental cost (i.e., changing proportionally).
3. It can be seen from the example below that the elemental quantities generally adopt the values of the most significant cost parameters discussed here and below.
4. The estimated cost of a building is calculated based on the total of (elemental quantity x elemental unit rate).
   • 
5. It takes into account the different forms, provisions and standard of the proposed new building better than the average unit cost per floor area.
6. It is therefore a more accurate method than the superficial method.
7. However, while the elemental quantities are simple to measure, the elemental unit rates would rely on reliable cost data from other projects or may need careful build-ups.
8. This method should only be used at the early stage of design.
9. At the time of the elemental quantity cost estimates, there would not be much details to measure approximate quantities and one has to rely on past cost analyses or some estimated quantity factors and ratios to estimate the elemental unit rates.
10. The elemental unit rates, quantity factors and ratios should be critically reviewed to see whether they should remain unchanged or adjusted when the design of the building is changed even though the elemental quantities can remain unchanged.
11. The price levels of past projects must be adjusted to the present day for use.

(image updated, 5/3/2023)

Approximate quantity method (按分項大約工程量計算)

1. The estimated cost of a building is calculated based on the total of (approximate quantity of major item of work x unit rate per quantity of major item of work inclusive of costs of minor items):
   • 
2. It does not usually show the elemental quantities and elemental unit rates just to save time.
3. As the design is more developed, it is possible to measure the work constituting the building more accurately and apply more appropriate unit rates relevant to the materials and standard chosen.
4. The quantities are approximate to reduce the time to measure so that a quicker cost estimate can be produced to reflect the updated cost of the design and enable any subsequent measures to control any unexpected costly design.

(image updated, 5/3/2023)

Condensed elemental method using the most significant cost parameters

1. Users of the elemental quantity method may find that many elemental quantities are the same for different elements and can in fact be reduced into a few most significant cost parameters:​​​​​​​​​​​​
   • Floor area (above ground + below ground)
   • Ground area (= roof area)
   • Transfer structure area
   • External elevation area
   • Basement screen wall area or more effectively basement volume of excavation
   • Site area
   • External area (site area - ground area)
   • Number of equipment
   • Refrigeration tonnage
   • Other elemental quantities.
2. The estimated cost of a building is calculated based on the total of (quantity of the above cost parameter x composite unit rate per quantity of cost parameter).
3. This can provide a quick and equally reliable cost estimate though not as detailed as the elemental quantity cost estimate.

​​​​​​​Adjust published unit costs per floor area

1. Some Consultant QS firms publish unit costs per floor area for public information.
2. When using these unit costs, care should be exercised to understand the scope of inclusions and exclusions, and their applicability.
3. The General Practice Division of the Hong Kong Institute of Surveyors has published a Building Cost Pro-Forma for Private Sector Developments in Hong Kong.pdf.
4. This should serve as a useful checklist, but the items and figures suggested there should be verified for individual projects.

Presentation of cost estimates

1. Rounding off:
   • The quantities, unit rates and costs should be suitably rounded off.
2. Word wrapping:
   • Text in table cells should be word-wrapped to avoid hiding of text at the end.
3. Comparison tables:
   • When the cost estimates need to give comparison tables to show different options and the differences between options to help reading and appreciation of the relative costs, instead of showing all the columns of each option together, the columns can be re-arranged in the following sequence to save some space and enable easier reading:

• When spanning over more than one page, the Item and Section columns and column header rows should be repeated.
• The contents under the Remarks columns can be very flexible, for adjustment methods, calculations, rationale, etc., subject only to space limitation.
• The remarks can be “Assumed no change”, “Original qty x 2”, “Original rate x 1.2”, etc.
• If there is not enough space, and the remarks are repeating, just insert “(a)”, “(b)”, “(c)”, in the Remarks columns, and define them below the table to mean:
  • Legend:
  • (a) Assumed no change
  • (b) Original qty x 2
  • (c) Original rate x 1.2 for higher rate due to complexity.
• Instead of showing the quantity and rate adjustments separately, the adjustment can be made directly against the cost, such as:
  • Legend:
  • (a) Option 1 CFA / Original CFA = 2
  • (b) Original cost x 2
  • (c) Original cost x 2 x 1.2 for higher rate due to complexity
  • (d) Original cost x (new elemental qty / original elemental qty) x (new elemental unit rate / original elemental unit rate).
• Example (d) can in fact save the need to show the columns for elemental qty, unit and unit rates.
• The adjustment calculations can also cover inflationary factors.

Comments on specific ICMS Sub-Groups

Foundation piling

1. Scope:
   • This Sub-Group includes all foundation piling underneath the building with or without basement.
2. Elemental quantity:
   • Foundation piling supports the whole building.
   • Its costs are more related to the total construction floor area (CFA) of the building including the basement CFA, which should be used as the elemental quantity.
   • Elemental unit rate:
     • Equals to unit cost per construction floor area based on some similar projects.
3. Approximate quantities:
   • The costs can be estimated, after consulting the Structural Engineer for a preliminary design, based on:
     • Piling plant mobilisation and demobilisation – Item
     • Piles – Number with each length/depth stated or total length/depth
     • Pile testing – Item.
   • It should be noted that the pile depths in ground and the pile core lengths are two different things.
   • All ancillary work not measured should be allowed for in the rates.

Foundations up to top of lowest floor slabs

1. Scope:
   • This Sub-Group includes that shown in blue below (pile caps, footings, substructure columns and walls, and lowest floor slabs and beams) beyond the footprint of the basement, and excludes foundation piling.
   • 
   • Foundations (excluding piles) underneath the basement are usually integrated with the basement bottom and should therefore be included in the “Basement sides and bottom”.
   • Therefore, this Sub-Group's costs are not related to the basement footprint or the basement floor areas.
2. Elemental quantity:
   • Pile caps, footings and substructure columns and walls, which support the whole building, are more related to the total CFA and building height.
   • Lowest floor slabs and beams are more related to the ground area (GA) of the building.
   • On the conservative side, the total CFA should be used as the elemental quantity to obtain the elemental unit rate for future references.
   • However, when applying this elemental unit rate to a building of significantly different building height and different CFA to GA ratio (approximately equal to the number of floors), the elemental unit rate can be broken into two parts for application.
   • For example, from the cost analysis of a reference building:
   • 
   • The unit rates at (a) and (d) can then be applied to the proposed building, subject to further adjustments for other dissimilarities.
   • Similar method can be adopted to split the elemental unit rates into different parts to handle those parts which do not vary in proportion to the elemental quantity.
3. Approximate quantities:
   • For approximate quantity cost estimates, the costs can be, after consulting the Structural Engineer for a preliminary design, estimated based on:
     • Excavation (rates to include disposal) – volume of excavation from commencing level of excavation to bottom of blinding layer with allowance for working spaces beyond the volume of the concrete work
     • Lateral supports in the form of planking and strutting for shallow excavation – allowed for in the rates for excavation
     • Lateral supports in the form of planking and strutting for deep excavation – as described for “Basement sides and bottom”
     • Raft footings, pile caps, column bases, wall footings, strap beams and tie beams – concrete volume, formwork area and reinforcement weight
     • Substructure walls and columns – ditto
     • Lowest floor slabs and beams – ditto
     • Lift pits – number.
   • ICMS gives a good checklist of the above.
   • All ancillary work not measured should be allowed for in the rates.
   • The concrete member sizes can be based on the preliminary design drawings.
   • Simplification into approximate average sizes x number can speed up the measurement.
   • It may even be quicker to estimate the average thickness per the building footprint from the preliminary design drawings or from some reference projects of similar height or adjusted for the differences in heights.
   • Following the same logic, the composite elemental unit rate build-up can be as follows:
     • Average concrete thickness / building footprint @ $/m3
     • Average formwork area / building footprint @ $/m2
     • Average concrete thickness / building footprint x steel ratio kg/m3 concrete @ $/kg
     • Average excavation depth / building footprint @ $/m3
     • Sum of the above = composite rate / building footprint
   • Of course, the concrete thickness and steel ratio should have taken into account the building height.

Basement sides and bottom

1. Scope:
   • This Sub-Group includes that shown in blue below (sides and bottom) of a basement and excavation for the basement, and excludes foundation piling.
     • 
2. Elemental quantity:
   • This is a difficult Sub-Group for choosing the appropriate elemental unit because:
     • part of its costs is related to the volume of the basement (excavation, disposal, and shoring and strutting)
     • part related to the basement footprint (basement bottom)
     • part related to the side area (basement side and vertical retaining support which can be twice the basement depth).
   • The volume of the basement should be the best choice for use as the elemental quantity.
   • The basement floor area may also be a reflection of the volume.
   • However, it would be better to estimate the costs from a number of approximate quantities rather than a single elemental quantity.
3. Approximate quantities:
   • For approximate quantity cost estimates, the costs can be, after consulting the Structural Engineer for a preliminary design, estimated based on:
     • Excavation (rates to include disposal) – volume of excavation from commencing level of excavation to bottom of blinding layer with allowance for working spaces beyond the volume of the concrete work
     • Vertical lateral support – area of excavated surfaces retained (from commencing level of excavation to bottom of blinding layer) x 2 or more to account for the embedded depth below the blinding layer
     • Horizontal or raking shoring to lateral support - area of excavated surfaces retained (suitable for raking shoring) or volume of excavation (suitable for flying shoring, i.e. horizontal shoring spanning across the whole site with intermediate vertical posts to support), unless more detailed measurement is used
     • Bottom slabs and blinding (including all foundations underneath but excluding piles) – concrete volume, formwork area and reinforcement weight
     • Basement sides – area
     • Vertical waterproof tanking, drainage blanket, drains and skin wall – area of tanking
     • Horizontal waterproof tanking, drainage blanket, drains and topping slab – area of tanking
     • Insulation – area
     • Lift pits, sump pits, sleeves – number of lift pits and sump pits.
   • ICMS gives a good checklist of the above.
   • All ancillary work not measured should be allowed for in the rates.
   • The concrete member sizes can be based on the average thicknesses from the preliminary design drawings or from some reference projects of similar height or adjusted for the differences in heights.
   • Simpler cost build-up can take the following form:
     • Volume of excavation – composite rates to cover excavation, disposal, and horizontal or raking shoring per m3 of excavation
     • Area of basement bottom – composite rates to cover all horizontal elements, with different ratios per basement bottom area to account for different elements
     • Area of basement sides – composite rates to cover all vertical elements, with different ratios per basement side area to account for different elements
     • Lump sum – to cover other standalone elements.

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Basement suspended floors (up to top of ground floor slabs)

1. Scope:
   • This Sub-Group includes all structural walls and columns, beams, slabs and staircases inside the basement, but excludes basement sides and bottom.
2. Elemental quantity:
   • The elemental quantity should be the CFA of the basement.
   • Elemental unit rate build-up (per basement CFA):
     • Similar to that for the "Frames and slabs".

Frames and slabs (above top of ground floor slabs)

1. Scope
   • This Sub-Group includes all structural walls and columns, beams, slabs and staircases above the top of ground floor slabs.
2. Elemental quantity
   • The elemental quantity should be the CFA above ground, not the total CFA including the basement CFA.
   • Elemental unit rate build-up (per CFA above ground):

• The quantity ratios are usually based on some similar projects or by sampling based on a typical bay.

Roof beams and slabs for Buildings under "Structure"

1. Scope:
   • Roofs can occur at the top of buildings or at lower floors. Any suspended floor without cover above is considered as a roof.
   • “roof beams and slabs” for Buildings should also include such roofs at the top or at lower floors.
   • In principle, the roof area on plan at various levels should be equal to the projected building footprint area on plan.
     • ​​​​​​​
2. Elemental quantity:
   • The elemental quantity should be the roof area if roof beams and slabs are separately estimated.
   • Otherwise, it should be part of the total CFA including the basement CFA.

External elevations

1. Scope:
   • This Sub-Group includes all external walls including applied finishes, cladding, curtain walls, windows, doors, shop fronts and shutters on the external elevations, but excludes external structural walls.
2. Elemental quantity:
   • The elemental quantity should be the external elevation area.

   • ICMS defines it as "total area of external wall finishes, facade cladding and curtain walls, windows, doors, shop fronts, roller shutters, fire shutters, etc. on the external elevations including all surfaces of

     external railings, parapets and features, but ignoring the presence of canopies".

   • Elemental unit rate build-up (per elevation area):

• a%+b%+c%+d% = 100% elevation area.
• The percentages are approximate proportions of the total external elevation area of a sampled section of the elevation.

Roof finishes, skylights and landscaping (including waterproofing and insulation)

1. Scope:
   • This Sub-Group include those to such roofs at the top or at lower floors.
2. Elemental quantity:
   • Roof area
   • Element unit rate build-up:
     • Similar to other Sub-Groups.

Internal divisions

1. Scope:
   • This Sub-Group includes ​​​​​​​​​​​​​​​​​​​​​all kinds of divisions including internal windows, doors and shutters.
2. Elemental quantity:
   • The elemental quantity can be the total CFA including the basement CFA.
   • Element unit rate build-up (per CFA):

• The quantity factors are based on a similar project or approximate wall areas per construction floor area of a sampled floor, which layout may be just an educated guess.
• The wall areas have door openings deducted.
• The elemental quantity can also be the total wall areas without deducting door openings

• The elemental unit rate build-up will then be (per total wall area):

• a% + b% = 100%.
• # = after deducting cost of wall.
• The percentages are approximate proportions of the total wall area of a sampled floor, which layout may be just an educated guess.

Fittings and sundries

1. Scope
   • This Sub-Group basically includes all the metal work and joinery, and interior landscaping.
2. Elemental quantity
   • The elemental quantity can be the total CFA including the basement CFA, or the relevant functional quantity.
   • Elemental unit rate:
     • Generally based on similar projects.

Finishes under cover

1. Scope
   • This Sub-Group includes all floor and ceiling finishes and false ceilings whether internal or external, and internal wall finishes and cladding.
2. Elemental quantity
   • The elemental quantity can be the total CFA including the basement CFA.
   • Elemental unit rate build-up of floor finishes (internal and external) (per CFA):

• a%+b%+c% = an estimated percentage of floor area / CFA after deducting voids, and wall and column base areas, i.e. less than 100% of CFA.

• Elemental unit rate build-up of internal wall finishes and cladding (per CFA):

• The quantity factors are based on a similar project or approximate internal wall finishes areas per CFA of a sampled floor, which layout may be just an educated guess.
• Note the approximate formula: internal wall finishes = internal wall area x 2 + external wall area.
• False ceiling voids and unfinished lift shafts would affect this formula.

• Elemental unit rate build-up of ceiling finishes and false ceilings (internal and external) (per CFA):

• a%+b%+c% = an estimated percentage of the ceiling area / CFA after deducting voids, and wall and column areas, but adding beam sides, i.e. more than 100% of CFA.

Services and equipment

1. The costs of services and equipment are generally estimated based on $/CFA for each sub-system.
2. If part of the building is not served by a sub-system, the CFA used may be only the area served.
3. In the case of toilets and kitchens, the estimate may be based on the number of toilets and kitchens.
4. For a more detailed cost analysis or cost estimate, the costs can be broken down into the following portions:
   • Costs related to main equipment (chillers, cooling towers, air handling units, transformers, boilers, etc.)
   • Costs related to terminal service outlets (air grilles, diffusers, lighting points, power points, sprinklers, speakers, cameras, sanitary fittings, etc.)
   • Costs related vertical up-feed and down-feed
   • Costs related to horizontal distribution
   • Costs related to isolated locations (e.g. toilets, kitchens, plant rooms, etc.).

Movement systems

1. While using the CFA as the elemental quantity for movement systems cannot be treated as wrong particularly when the CFA is big and there are many lifts and escalators, the cost should better be estimated based on cost per number of lift or escalator.

Elemental quantities based on % of other costs

1. It would be more appropriate to use % of other costs (base costs) as the elemental quantities to allow for preliminaries and risk allowances as the base costs may change when the CFAs remain the same.

Steel ratios

1. The steel ratios of structural walls and columns should be bigger than those for beams and slabs.

Unit cost / CFA of taller buildings

1. The $/CFA of foundations, substructure and structure should be higher for taller buildings because of increased loading on the lower floors and increased wind load.
2. The $/CFA of services and equipment should be higher for taller buildings because of longer running lengths of vertical pipes and cables, and increased lift speeds and capacities.
3. Refuge floor would need to be added.
4. Taller buildings take longer times to complete, causing higher unit rates and higher preliminaries costs. While it is usual to use the same % for preliminaries for different projects, when carrying out comparative cost studies for buildings with very different construction periods, the % should reflect the differences. Instead of adjusting all the unit rates, it may as well be simpler to adjust only the preliminaries to also cover the higher unit rates.

Composite rates for approximate quantities ​​​組合單價的測算

Composite items

1. The approximate quantity method measures major work items as composite items so as to reduce the need and time to break down the work items into components for detailed measurement.
2. Examples are:
   • lump sum allowances for mobilisation and demobilisation of major construction plant
   • m or No. piles of specific cross-sectional size
   • m3 excavation including disposal (backfill or remove from site)
   • m2 or m concrete members including formwork and reinforcement
   • m2 brick or block work including lintols
   • m2 cladding or curtain walls or window walls or windows including glazing
   • m or No. extra over m2 or m for special features
   • No. doors including frames, architraves, fixings, glazing, painting, fire rating, etc.
   • No. of major metal or joinery fittings
   • m2 roof finishes including surface layer, protective screed, waterproofing layer, levelling screed, insulation, etc.
   • m2 rendering including surface treatment
   • m2 plastering including painting
   • m2 tiling including screeding
   • No. of vertical stacks of water supply or disposal pipes including all pipe fittings and ancillaries
   • No. of kitchens or bath rooms or other serviced rooms including all sanitary fittings and branches
   • No. of sanitary fittings including all accessories
   • No. of terminal M&E fittings including conduits or wiring or cables
   • No. of main M&E equipment
   • m conduits or wiring or cables
   • m2 ducts
   • lump sum allowances for sundries
   • lump sum for or No. of costly tests
3. Different sizes or types may be separated or grouped together depending on their cost significance.
4. Average sizes may be stated or varying sizes deemed.

Composite rates

1. Building up of composite rates would be required for such composite items.
2. Buffers should be allowed in the approximate quantities and composite rates to cover the costs of unmeasured minor items.

Using BIM

• When preliminary BIM models are used to generate quantities for preparing cost estimates, the quantities would not reflect the work items not modelled. Extra allowances in the approximate quantities or the composite rates should be made to cover the costs of unmodelled but necessary items.

Build-up of composite rates using properly set out dimension tables

1. The following gives examples of composite items and build-ups of composite rates.​​​​​​​
2. Example 1:
   • 
   • 
   • ​​​​​Note that in Hong Kong, beam concrete and formwork are measured those parts below slab soffit. Beam reinforcement includes those at the intersection of slab and beam.
3. Example 2:
   • ​​​​​​​​​
   • Note that a typical bay of 6 x 6 m is measured to average out the beam quantities.
   • Note also that the four beams around each typical bay are shared with adjacent slabs, and their quantities are therefore halved.
4. Example 3:
   • ​​​​​​​
5. Example 4:

Handling empty cells instead of entering “1”

1. 
2. Note that 36.00 at cell I46 uses the formula: "=PRODUCT(C48:H48)" which can treat empty cells within the range of C48:H48 as 1 without the need for entering 1.
3. However, if the individual cell values within the range of C48:H48 contain more than 2 decimal places, the PRODUCT() function using the hidden values will not give the same result as the displayed value. To ensure proper match, a formula based on the displayed values should be used. Such accuracy would be required for Bills of Quantities and Final Account and should not be needed for Cost Estimates.

(added, 5/3/2023)

Using dash lines to bound ranges

• Note that 65,917 at cell L46 uses the formula "=SUM(L47:L54)" which covers the range from the upper dash line to the lower dash line. Those dash lines embrace the rows of constituent items between them and ensure that the formula will not be corrupted due to addition or deletion of rows.

(added, 5/3/2023)

Round unit rates to 2 significant digits

1. Note that 1,900 = 65,917/36.00 = 1,831.03 has been rounded up to two significant digits as 1,900.
2. The formula used is "=IF(INT(L46/I46)>0,ROUNDUP(L46/I46,2-LEN(INT(L46/I46))),ROUNDUP(L46/I46,2))".
3. L46/I46 is the quotient. Let's call it "Q".
4. The formula will become "=IF(INT(Q)>0,ROUNDUP(Q,2-LEN(INT(Q))),ROUNDUP(Q,2))".
5. It can be read as: if integer of Q > 0, then round it to 2 significant digits, else round up Q to 2 decimal places).
6. INT(Q) = 1831.03, it is > 0.
7. 2 - LEN(INT(Q)) = 2 - 4 = -2.
8. ROUNDUP(1831.03, -2) = 1900.
9. If Q = 0.1234, then ROUNDUP(Q, 2) = 0.13.
10. The unit rates used in Cost Estimates are approximate rates.
11. It would not make sense to show them in many digits and with decimal places to make them look like very accurate.
12. 2 significant digits should be sufficient.
13. Estimates should include buffers.
14. Rounding up is appropriate.

(added, 5//3/2023)

Build-up of composite rates using compact format for showing in the Cost Estimate

1. The following shows another method to present the composite rate calculations in the Cost Estimate.
2. Example 5:
   • 
   • Note that the reinforcement refers to the concrete quantities already calculated at cells E15 and E23 above.
3. Example 6:
   • 
   • Note that the function FORMULATEXT() is used to display the formula of the quantity of 0.48 above for checking. The cell entry must be preceded with "=" for it to be recognised as a formula.
   • Using this function will eliminate the need to type the formula separately as an explanation in addition to entering the formula in the calculation cell and risking mismatch errors.
   • The formula column can be hidden or deleted when issuing the Cost Estimate.
   • Note also that the estimated costs have been rounded to the nearest 10,000, using the formula "=ROUND(Rate*Qty, -4)".
   • This would give the image that the figure is an approximate estimate rather than an accurate figure.
4. Example 7:
   • 
5. Example 8:

Prepare cash flow tables 編製現金流量表

Use S-curve 用S線圖

​​​​​​​​​​​​​​​​​​​​​

1. ​​​​​​​​​​​​​​Divide the horizontal axis into parts equal to the number of months of construction.
   ​​​​​​​將水平軸按施工的月份數目分段
2. For each month, interpolate from the curve the cumulative payment percentage on the vertical axis.
   利用曲線找出每個月在垂直軸相對的累計進度百份率
3. Find the monthly payment percentages from the cumulative percentages.
   用累計進度百份率計出每月進度百份率
4. Apply the monthly payment percentages to the total cost to obtain the monthly payment values.
   每月進度百份率乘總造價得出每月進度款。

Use Bar Chart Programmes 用條形進度計畫表

1. Follow the bar chart programme, assign the monthly payment percentages for each activity bar.
   跟從條形進度計企劃表，對每條活動配以每月進度百份率
2. Apply the monthly payment percentages to the total cost of each activity bar to obtain the monthly payment values.
   將每月進度百份率乘該條活動的造價得出每月進度款
3. Ensure that the total of each activity bar is correct.
   確保每條活動的合計無誤。

For both methods

1. Separate stage payments.
   要把分期付款及大型採購分列
2. Separate Retention.
   要把保修金分列
3. Watch out time lag between work carried out, payment certification and honouring of payment.
   注意施工、批款及付款的時間差。

4. Payment terms:

   • Usual payment terms for construction contracts in Hong Kong:
     • no advance payment;
     • monthly payments for materials delivered to site and work done subject to 10% retention on the gross total up to a maximum equal to 5% of the original Contract Sum;
     • half of the retention to be released upon Practical Completion / Substantial Completion (*); and
     • the balance to be released upon the issue of the Defects Rectification Certificate / Certificate of Completion of Making Good Defects / Maintenance Certificate (*) after rectification of defects found during the Defects Liability Period / Maintenance Period (*) usually of 12 months.
     • (*) = Different terms used by different standard forms of contract.
   • Possible payment terms for lift and escalator contracts / sub-contracts:
     • 10% upon award;
     • 20% when ready for shipment;
     • 30% on delivery to site;
     • 25% on issue of Use Permit by the EMSD;
     • 10% on Practical Completion / Substantial Completion; and
     • balance upon the issue of the Defects Rectification Certificate (as above).
   • Suppliers:
     • Usually require deposits or advance payments which can be moderately up to 30% or sometimes up to 50%.
   • Lower tiers sub-contractors:
     • Require shorter payment periods and no retention.

Reconciliation 概算變化的解釋

1. Presented vertically:
   垂直列出:
   
2. Presented side by side:
   並排表示:
   ​​​​​​​​​​​​​​
3. A legend of “(a)”, “(b)”, “(c)”, etc. can be used for stating common reasons, similar to the legends suggested for “comparison tables” under “Presentation of Cost Estimates” above.

Pre-tender Estimates ​​​​​​​標底

1. Method:
   • By pricing the Bills of Quantities before formal issue of tender documents or before return of tenders.
     在發出招標檔前或在回標前利用工程量清單套取單價計價。
2. Purposes:
   • For checking whether the cost so priced is within the previous estimate and the Budget
     以檢查得出的總價是否仍在前概算或投資預算之內
   • For making design changes and issuing tender addendum to keep the costs within the Budget
     作出設計修改並發出招標檔變更通知以便維持造價在投資預算之內
   • For checking against tenders returned for reasonableness
     用作評核回標價的合理性。

Intro

This gives some simple statements of principles of the law of contract. References have been made to "The Law of Contract, Fourth Edition 1974" written by W.T. Major in order to compile these statements.

Contract

1. A bilateral contract is created upon unqualified acceptance of an offer.
2. A unilateral contract is created upon the offeree's performance according to an offer.
3. An agreement "subject to contract" is not binding.
4. There must be an intention to create binding legal relations.
5. An agreement cannot oust the jurisdiction of the courts.

Offer

1. An offer must be clear, complete, and final.
2. An invitation to treat is not an offer.
3. A mere statement of price is not an offer.
4. An offer must be communicated to the offeree.
5. An offer may be communicated orally or in writing or be implied from conduct.
6. An offer to a particular person or group of persons can only be accepted by those persons.
7. An offer to the world at large can be accepted by any person having the notice of the offer and fulfilling the terms of the offer.
8. An offer can be withdrawn (revoked) at any time before valid acceptance.
9. An undertaking to keep the offer open for a specified time is not binding unless the offeree gave consideration in return for it to make it a binding contract (known as an option).
10. Revocation is effective if and when it is actually (including by post or indirectly) communicated to the offeree.
