1. ELEMENTAL COST ANALYSIS (ECA)
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 Elements Element of Quantity
Substructure
Area of lowest floor finish measured as for GFA
Frame
Area of floors relating to frame measured as for GFA
Upper Floors
Total area of Upper Floors
Roof
Area of measured overall surfaces
External Walls
Area of external walls measured an outer face (excluding openings)

6. BASIC ELEMENTS (CONT.) Basic elements Elements Element of Quantity
Windows and External Doors
Total area of windows and external doors measured over frame
Internal Walls and Partitions
Total area of internal walls and partitions (excluding openings)
Internal Doors
Area of internal doors measured over frame
Wall Finishes
Total area of wall finishes
Floor Finishes
Total area of floor finishes
Ceiling Finishes
Total area of ceiling finishes

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 PROCEDURE 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.
