2 Agenda Introduction Purpose – What’s the need? Why bother?
Evolution of the Standards Overview of the Standards

3 ICMS

4 What are the aims of ICMS?
Construction cost to be consistently and transparently benchmarked; The causes of difference in costs between projects can be identified; Properly informed decisions on the design and location of construction projects to be made; and Data to be used with confidence for project financing & investment, programme and decision-making and related purposes The standard will allow capital cost comparisons to be made across building and civil engineering projects (works). Whole lifecycle costs will also be included if possible, or a firm link developed to allow further work on this subject. It will: adopt universal definitions of construction costs and the associated variables; create a single classification system for building and civil engineering projects (works) for use with digital tools such as BIM; recommend a consistent data framework for the collation of national statistics; be as simple as possible, commensurate with allowing robust comparisons to be made; articulate with local standards and the IPMS wherever possible; recommend a standard reporting format; allow global cost comparisons and benchmarking for global investors, corporate bodies and contractors; provide a checklist for international best practice; when combined with IPMS, consistent cost comparisons on a per m2 basis; provide consistent language and terminologies for the worldwide, and increasingly mobile, profession; and accommodate the need for continuous refinement, updating and change.

5 Why are they important? Knowing what is, and what is not included in the construction cost of a project is vital to: Understanding how it compares with other projects within or outside that market Accurately assessing value-for-money Assessing and benchmarking project construction cost Reporting national and international statistics on construction output

6 Standards used today? The standards used today differ within countries and from one jurisdiction to the next Depending on where the project is located the costs might include some or all of the following elements: Labour and materials Land acquisition Professional Fees Client costs

7 Why are they important? Different approaches to presenting the costs of construction can produce results that vary by as much as 25-30% due to inconsistent methodology and standards

8 What are the implications of global inconsistency?
Inability to accurately compare project construction costs Investment risk Lack of transparency Leading to: Under-investment in construction projects Time and cost overruns

9 Who will benefit from ICMS?
Any party that has a direct or indirect interest in construction projects will benefit Those investing in or managing construction projects will benefit significantly Financial institutions will have a consistent basis for assessment of project funding requirements The public will benefit through enhanced, prudent assessments of public projects Benefits and users At a project level: Financial institutions, investors, clients, consultants, contractors and the supply chain. At a national level: Governments, regulatory and standards setting bodies, and national professional institutions. At an international level: Global financial institutions, investors, clients, consultants, NGO’s and global professional institutions and umbrella bodies.

10 Evolution – The ICSM Coalition
Formed on 17 June 2015 after a formal meeting at the International Monetary Fund in Washington DC Currently 44 coalition members including the ICE ICMS is being developed in two parts as follows: ICMS 1: Agree higher level cost centres and definitions for infrastructure (with buildings as a sub-set). Link cost centres and elemental headings with both UN ISIC (using ICMS 1) and IPMS (ICMS 2 in terms of building cost/m2); and ICMS 2: Define construction cost and harmonise building elemental headings and definitions at a project (management) level . Prepare a relationship map linking ICMS to IPMS.

11 Evolution – The Standard Setting Committee
An independent Standards Setting Committee (SSC) was established to draft the ICMS The SSC comprises 27 experts from around the world One private and two public consultations ICMS is being developed in two parts as follows: ICMS 1: Agree higher level cost centres and definitions for infrastructure (with buildings as a sub-set). Link cost centres and elemental headings with both UN ISIC (using ICMS 1) and IPMS (ICMS 2 in terms of building cost/m2); and ICMS 2: Define construction cost and harmonise building elemental headings and definitions at a project (management) level . Prepare a relationship map linking ICMS to IPMS.

12 Framework The hierarchical framework has four levels:
Level 1: Project or Sub-Project Level 2: Cost Category Level 3: Cost Group Level 4: Cost Sub-Group

13 Framework Project Sub - Project Cost Categories Cost Groups
Cost Sub-Groups

30 ICMS Partners

31 How can I get involved? Professional and standards-setting bodies are encouraged to join the coalition and to adopt ICMS. Private firms, universities and governments are invited and encouraged to become voluntary ‘partners’ and work with the coalition to develop, raise awareness of and implement ICMS.
