Reading materials

  1. Read the chapter on Pricing and Tendering of “Quantity Surveyor’s Pocket Book Second Edition” authored by Duncan Cartlidge, which gives examples of how to build up preliminaries prices and unit rates for measured works for tendering.
  2. Preview the “Code of Estimating Practice Seventh Edition” published by the Chartered Institute of Building at  https://books.google.com.hk/books?id=gBJDjH5S61wC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false. This book explains what a tenderer should consider at the time of tendering. Site inspection during tendering to understand all conditions on or around the site which may affect the carrying out of the Works should be carefully and thoroughly done, and the implications allowed for in the tender prices and completion times.

General principles

  1. Both describe the practice in the UK contexts. The wage rates, working rules, tax system, materials and productivity mentioned there may not applicable to Hong Kong, but the methodology and principles can be shared.
  2. Learn the following concepts:
    • Use all-in hourly rates
    • Include on-costs (not directly paid to the workers, plant hirers, suppliers and sub-contractors) on the direct costs
    • Use labour gang rates
    • Include costs of non-productive time (labour and plant) while payment is still needed
    • Distinguish between quantities measurable for payments from those quantities consumed (waste, breakage, theft, loss, shrinkage, bulking, unmeasured laps, minor items, etc.) but not measurable for payments and include the costs of those not measurable in the rates for the quantities measurable
    • Use representative sample size to calculate the total cost before averaging it to unit cost per quantity so that costs not directly proportional to the quantity can be shared by the unit rates.
  3. The volume of ground materials becomes bulkier after excavation and this will require bigger transportation means.
  4. Conversely, bigger volume is required to fill up a space because of compaction and packing.
  5. Concrete and cement mortar shrink after mixing.
  6. The cost impact should be taken into consideration.

Estimating from the first principle

  1. Estimating or building up the unit rates from their constituent costs is called “estimating from the first principle”. This is unlike using a unit rate from other projects.
  2. Such estimate would need a knowledge of the required constituent quantities of the materials, labour and plant in constructing a work item.
-> Top

Approximate materials, labour and plant constants (based on Quantity Surveyor’s Pocket Book”)

  1. Labour constants are not really constants and do vary depending on the site and weather conditions and work complexity. “Labour contents” is more appropriate.
  2. More decimal places have been given below for the sake of consistency only. It does not mean that the figures are as accurate as to the decimal places given.

Mainland, China

  1. National standard price books:
    • China has published national standard price books giving unit rates for all common items for all kinds of construction works.
    • It has also published materials, labour and plant contents (“quotas”) for building up the unit rates.
    • As they are national standards, provinces and cities use them as the base to publish local price books and quotas to cater for local conditions.
    • The unit rates are direct costs.
    • Further additions are required to cover indirect costs, overheads, profits, taxes and charges, which usually use part or whole of the direct costs as the base for percentage mark-ups.
  2. Old practice:
    • In the old days, the price books and quotas were rigidly applied.
    • The mark-up factors were regulated by the central or local governments.
    • As the unit costs of materials, labour and plant might vary, local supervisory authorities published as and when necessary cost adjustment factors to be applied on the relevant general materials, labour and plant costs.
    • Uncommon materials’ costs might be adjusted individually.
    • The central or local governments or local supervisory authorities also adjusted the mark-up factors as and when necessary.
    • Instead of adjusting the unit rates individually, the relevant costs were extracted and summed up to serve as the bases for adjustments.
    • This was a tedious process if done manually when software was not available.
    • The same system and method were applied to tender pricing.
    • This means that the unit rates were not all-in rates. In order to calculate the cost effect of changing 1 unit quantity of work item, one would need to make many adjustments to the unit rate to get the total cost.
    • Using the same fixed sets of unit rates, quotas, mark-up factors and adjustment factors mean that all tenderers’ unit rates should be the same, and this would mean no competition.
    • The unit rates would not truly reflect the productivity of individual contractor.
    • This was more like an accounting system when the contractors were all state-owned and appointed by the local supervisory authorities to individual projects without the need for competitive tendering.
  3. Later practice:
    • Later, China promoted competition, and allowed the tenderers to compete the price levels, but still required them to follow the quotas per unit quantity, i.e., separating the constituent quantities and costs making up the unit rates.
    • However, if a tenderer genuinely estimates the unit cost but is bound to use the same constituent quantities, he has to adjust the constituted unit costs to compensate.
    • This would mean both the constituent quantities and unit costs would not be genuine.
    • Nowadays, to ensure competition based on the tenderers’ own productivity, China has given greater flexibility for the tenderers to estimate their unit rates without strictly following the price books and quotas.
    • However, the standard price books, quotas and pricing system still have great influence and guiding effects.

Hong Kong

  1. Hong Kong does not have a publicly published set of materials, labour and plant contents, while contractors may have their in-house data.
  2. However, whether most of them have such data is doubtful, because contractors would usually rely on and require their sub-contractors to quote unit rates per work or supply quantity, even for labour-only sub-contracting.
  3. Only the lowest tier of sub-contractors (usually labour-only sub-contractors) may need to estimate the labour contents.
  4. They may as well quote based on past project unit rates with adjustments.
  5. In case of labour-only sub-contracting, the contractors would need to estimate the materials and plant contents.
  6. In this connection, correct estimate of the materials’ waste factors is very important, and should not rely simply on the published waste factors applicable outside Hong Kong.
  7. When preparing the final accounts, it may be required to find out the labour contents allowed for in the unit rates.
  8. The way to do it is to subtract the more certain material costs from the all-in unit rates first and dividing the remainder by the daily wage rate to obtain the mandays required.
  9. The mark-ups for profit and overheads and the plant costs should also be dealt with in the calculation.
-> Top

Direct costs

  1. The costs of materials, labour and plant directly incurred due to the carrying out of a specific work item is called “direct costs”.
  2. Direct” means that if the quantity of the work item is changed, the costs will also change sensitively.
-> Top

Indirect or overhead costs

  1. There are indirect costs which are costs of supporting work or services which are not directly related to or do not sensitively change relative to the quantities of a specific type of work items but are commonly required and shared by more than one type of work items. They are called “overheads”.
  2. There are two kinds of overheads. One is called “head office overheads”. The other is called “site overheads” or "project overheads”.
-> Top

Head office overheads and profit

  1. Head office overheads are the costs of running the contractor’s company whether a particular project is undertaken or not.
  2. However, all projects on hand must contribute to support the head office overheads. Since head office overheads are continually incurred, timely contribution is important. If the contribution from a particular project has become low or slow, the company will suffer. If the cause of the loss is something for which the Employer is responsible under the construction contract, this will be a matter for claims.
  3. A contractor’s annual profit and loss account statement may show the following:
    • Turnover (prices received from projects)
    • Less Cost of sales
    • Gross profit
    • Add Other income
    • Less Administrative expenses
    • Profit before tax
    • Less Profits tax
    • Profit after tax.
  4. The administrative expenses may include:
  5. Head office staff salary
    • Director's remuneration
    • Mandatory Provident Fund
    • Audit fee
    • Bad debt
    • Bank charges
    • Cleaning
    • Computers, accessories and software
    • Currency revaluation difference
    • Depreciation
    • Entertainment
    • Insurances
    • Loss on disposal of fixed assets
    • Postage and courier
    • Printing and stationery
    • Professional fees and charges
    • Rents and rates
    • Repair & maintenance
    • Staff welfare
    • Sundry expenses
    • Telephone and fax
    • Travelling expenses
    • Water and electricity.
  6. The profit is whatever left over after subtracting the costs and expenses from the prices.
  7. The profit and overheads allowed for in tenders are usually calculated as percentage mark-ups on the direct costs (i.e., cost of sales).
  8. If the account is healthy, to maintain the same level of contribution to profit and overheads:
    • The percentage mark-up for gross profit (i.e., including overheads) would be
      • = Gross profit / Cost of Sales
    • The percentage mark-up for head office overheads would be
      • = Administrative expenses / Cost of sales x 100%
    • The percentage mark-up for net profit (i.e., excluding overheads) would be
      • = Gross profit percentage – head office overheads percentage.

Site or project overheads

  1. Site overheads or project overheads are the costs which are incurred on top of the regularly incurred head office overheads when a project is undertaken, and are those costs of commonly shared work or services not priced as part of the direct costs of the permanent work items.
  2. Project staff do not necessarily station on the site all the time.
  3. Site/project overheads may be priced as a percentage mark-up on the direct costs, but major costs would usually be priced in the Preliminaries Bill or Specification Preliminaries Section.
  4. See headings of preliminaries items.
  5. Preliminaries items should also be priced based on direct costs plus profit and head office overheads.
