ASSIGNMENT 2

Elemental Cost Analysis (ECA)

 

 

This group assignment constitutes 10% of the total assessment where a group of up to 8 students will prepare detail cost analysis of a building project culminating in the preparation of a ECA report.

​

As for our group, we have 12 members in total. The purpose of elemental cost analysis is to show the distribution of the cost of a building among its elements to permit the costs of two or more buildings to be compared. A cost that is obtained from cost analysis is insufficient to determine the actual price. It has to take into account the conditions and the details of the project and the quality and quantity of work involved.

 

The cost analyses can be used to fulfill four main purposes. Firstly, to enable designers and building clients to appreciate how cost is distributed among the functional components of a building. Secondly, to help designers and building clients to develop ways in which costs could be allocated to produce a better balanced design. Furthermore to allow prompt remedial action on receipt of high tenders, by indicating the components where reductions in cost are possible. Lastly, to assist in the cost planning of future projects by comparison of cost analyses.

​

When preparing elemental cost analysis, we need to have the following items :-

• Complete contract document (a successful tender which includes bills of quantities, list of prime costs sums, etc.)

• Working drawings and the specification to calculate the quantity factor and others.

• Tender report-to obtain information regarding the market, number of tenders, etc.)

• Manual for preparing cost analysis

• Standard form for cost analysis

​

Through this assignment, I've learnt the importance of teamwork. Our leader, Albert plays an important role, he guides us throughout the whole progress and divided all the tasks equally among us. As for me, I'm in charge of calculating circulation area as well as windows and external doors. I'm glad that the efforts that we've put in eventually became a success and it's really fun along the way we produce ECA. I've learnt how to count for Gross Floor Area (GFA) at last. Most importantly, we have to thank Mr. Loo for guiding us throughout this assignment.
