Note

  • 15/3/2022: Expanded.
  • 7/3/2022: Split from Pre-Contract Cost Planning and Control.

Intro

  1. International Cost Management Standard (ICMS) (https://icms-coalition.org/the-standard/), formally called "International Construction Measurement Standards", is intended to provide global consistency in presenting construction life cycle costs and carbon emissions.
-> Top

Aims

  1. Provide global consistency in classifying, defining, measuring, recording, analysing and presenting entire construction life cycle costs and carbon emissions at a project, regional, state, national or international level.
  2. Allow costs and carbon emissions to be managed and potentially reduced.
  3. Allow:
    • construction life cycle costs and carbon emissions to be consistently and transparently benchmarked (comparative benchmarking)
    • the causes of differences in life cycle costs and carbon emissions between projects to be identified (option appraisal)
    • properly informed decisions on the design and location of construction projects to be made at the best value for money (investment decision-making) and
    • data to be used with confidence for construction project financing and investment, decision-making, and related purposes (certainty).
-> Top

Characteristics

  1. Global: co-existing with the locals.
  2. High level.
  3. For the first time, building works, civil engineering works and carbon emissions are now also covered by the same classification at the high level.
  4. Same for costs and carbon emissions.

Timeline

  1. 17 June 2015: Formation of ICMS Coalition – a non-governmental, not-for-profit professional coalition.
  2. November 2015: Standards Setting Committee starting to work.
  3. July 2017: Release of the 1st Edition covering capital construction costs of building and civil engineering works,
  4. August 2019: Release of the 2nd Edition extended to cover other life cycle costs and more civil engineering project types at the PAQS Congress in Malaysia.
  5. November 2021: Release of the 3rd Edition extended to cover carbon emissions and more civil engineering project types. Change of names to International Cost Management Standard and Standard Setting Committee.

Evolution of cost classification

 

  1. "elements" in the traditional QS sense was called "Cost Groups" and "Cost Sub-Groups" in ICMS 1 and 2.
  2. With the addition of carbon emissions in ICMS 3, it is now called "Groups" and "Sub-Groups" to make them common for costs and carbon emissions.
-> Top

Hierarchical framework

  1. Simple
    • This framework is simpler than that commonly used in Hong Kong, which is for building works only.
  2. Shared groups
    • Construction, Renewal and Maintenance all share the same Groups.
  3. Composite and prefabricated work
    • It is covered.
  4. Development budget
    • For new developments, the total of the Acquisition Costs and Construction Costs represents the capital cost of development or development budgetary cost.

-> Top

Codes

  1. Code: 01.2.03.030
    • Meaning: Buildings: Construction: Structure: Frames and slabs (above top of ground floor slabs).
Level 1 Project Type 01. Buildings
Level 2 Category 2. Construction
Level 3 Group 03. Structure
Level 4 Sub-Group 030 Frame and Slabs
-> Top

Relationship between ICMS, LCC and WLC

  1. ‘Occupancy Costs’ are considered part of the ‘Non-Construction Costs’.
  2. Compatible with ISO 15686-5:2017 Buildings and constructed assets – Service life planning – Part 5: Life-cycle costing.
-> Top

Carbon reporting framework

  1. The reporting structures for costs and carbon emissions are identical.
-> Top

Groups and Sub-Groups

Rationale for some classifications

-> Top

Composite or prefabricated work

  1. There are items for ‘composite or prefabricated work’, but in principle their costs and/or carbon emissions are to be split into the relevant Groups and Sub-Groups as much as possible to facilitate analysis and comparison with non-composite or prefabricated work.
  2. Include in the ‘composite or prefabricated work’ only if the composite or prefabricated work integrates different construction components across different Groups and Sub-Groups serving the functions of more than one Sub-Group and is priced without further breakdown in the contract.

Substructure and Structure Delineation

  1. “Superstructure” is not used.
  2. The “Substructure” and “Structure” delineation for various project type is shown in the diagrams below.
  3. Why are they delineated into “Substructure” and “Structure”, not “Substructure” and “Superstructure”?
  4. Usually, substructure refers to the structure below the ground surface and superstructure refers to the structure above ground.
  5. However, as shown in the diagrams, many of the main structures for civil engineering works (such as roads, tunnels, tanks, pipelines, wells, boreholes, etc.) can be totally below the ground surface, if these main structures are classified as substructure, there would be nothing left to be reported for the superstructure.
  6. Therefore, ICMS classifies all the main structures as “Structure” whether or not they are underground or underwater, and classifies all structures supporting or encasing the main structures as “Substructure”.

Split of Basement for Buildings

  1. The basement sides and bottom (shown in deep blue in the diagram below) are classified as an item (code [2|3|5].02.030.030) under the Substructure Group, while the basement suspended floors (shown in red box in the diagram below) are classified as a Sub-Group (code [2|3|5].03.020) under the Structure Cost Group.
  2.  
  3. Why are the basement sides, bottom and suspended floors not grouped together as substructure or basement, like common language use? It is also usual for tender pricing to group the basement works under a section.
  4. Answers:
  5. The design of the basement sides and bottom do not vary in direct proportion to the total building floor area nor to the total basement floor area, and is highly dependent on the site conditions even for the same building design. The cost of the basement sides and bottom should therefore be reported separately from the cost of the basement suspended floors.
  6. If the basement suspended floors are reported separately from the superstructure, the “unit cost per total building floor area” of the basement suspended floors ($400/m2) and of the superstructure ($2,700/m2) as given in the high-level cost summary, as shown in the example below, would not be useful when one wants to roughly estimate how much a similar building of 12,000 m2 would cost. One would need to know the floor areas of the basement and the superstructure or their proportions, and use $4M and $27M for pro-rata calculations.
  7. While it may be easy to separate the architectural works | non-structural works into basement and superstructure, it would not be logical from the costing point of view to do a similar separation for services and equipment because it is often required to put main services and equipment serving the whole building in the basement, but allocating the costs of main services and equipment based on their locations would give a misleading unit cost per basement floor area and unit cost per superstructure floor area for further use.
  8. If the basement suspended floors and superstructure are grouped together, the unit cost per total building floor area ($3,100/m2) as shown in the example below would then be more useful for quick pro-rata calculation and comparison. Furthermore, per their respective floor areas, the design of the basement suspended floors is generally heavier than that of the superstructure, but the former is exclusive of external structural walls, while the latter is inclusive. The two aspects can have an off-setting effect such that $4,000/m2 and $3,000/m2 in the above example can be closer to each other, and grouping together would be appropriate.
  9. ICMS is for high-level cost presentation for comparative benchmarking and option appraisal, etc. The above classification should make the unit costs more readily useful for such purposes. For tender pricing, users can choose to group the basement works in their preferred ways.
  10. If one wants to show the basement and superstructure costs separately in the cost report to match the sections in tender pricing, one can adopt the following presentation:

External structural walls as structural parts vs External elevations

  1. Some cost classifications classify external structural walls as part of the “External elevations” or as “External walls” whether above or below ground. Why does ICMS 2 not so classify but classify the external structural walls as structural parts?
  2. Answers:
  3. External structural walls serve two functions, one taking structural loading of the building, and the other enclosing the building. 
  4. It is considered difficult to separate the external structural walls (reinforcement in particular) at “A” below from the rest of the core structure, and it would give an incomplete structural cost if both the external structural walls at “A” and “B” below are grouped under “External elevations”, say, when answering the question “what would be the structural cost without non-structural parts?”. 
  5. For construction, the structural parts should come first before the non-structural parts are added on. Therefore, the external structural walls are classified as structural parts under:
    • [2|3|5].02.030: Basement sides and bottom – sides
    • [2|3|5].03.030: Structure – Frames and slabs – structural walls and columns
  6. For present day buildings, the design of the external structural walls above ground and that below ground can be very different, the walls are therefore separated as above.

Fitting out lighting fittings / Supply of sanitary fittings

  1. Lighting fittings (decorative) and sanitary fittings are usually chosen by the architects instead of the building services engineers, and their costs are not usually included in the cost estimates provided by the engineers, they are therefore separately as two Sub-Groups.
  2. However, since they are more related to Services and Equipment, they are therefore included as part of “Services and Equipment”.
-> Top

Builder's profit and attendance on services

  1. Services and equipment are likely the subject of nominated sub-contracts on which the builders price profit and attendance separately. This Sub-Group is intended for such profit and attendance.
  2. The costs of other works should include profit and attendance.
