  1. What successful Cost Estimators know….and you should, too. ELEMENTAL COST ANALYSIS (ECA) Prepared by: Assoc. Prof. Sr Dr. Mastura Jaafar

  2. WHAT IS ECA? As a systematic breakdown of the cost of a building to a Client into various building/construction elements in terms which are meaningful to both Client and the members of the Design Team. (ISM)

  3. OBJECTIVES OF THE ECA • To enable the Design Team to determine how much had been spent on each building element. • To assess whether a balanced distribution of costs have been achieved amongst the various elements of the building. • To provide comparison of costs of the same elements that may be used in different buildings. • To obtain cost data for use in the cost planning for other projects.

  4. BRIEF SPECIFICATION • Brief specification in the ECA describes the type and quality of materials to be used in project. • Usually consists of 6 elements: substructure, superstructure, finishes, fittings and furnishings, services and external works

  5. BASIC ELEMENTS • Basic elements

  6. BASIC ELEMENTS (CONT.) • Basic elements

  7. COST PLANNING • To be able to carry out elemental estimating based on historic data. • This data is then manipulated to suit the requirements of the current project under consideration. • A good cost planning will store its data in the appropriate form for later retrieval. This usually takes the form of elemental cost analysis.

  8. COST PLANNING • Form 1 • Calculating Gross Floor Area (GFA) and Total Cost of Element – Form 2 • Up date specifications – Form 3 • The Cost Estimate for the new project is ready. PROCEDURE

  9. FORM 1 Type of building

  10. FORM 2
