estimate

1. Feasible

2. Functional

3. Technical

4. Financial



OUTLINE PROPOSALS

Overall sketch design will be established but still

category

Design team

Evaluate cost implications of differing

design solutions

Preparing outline cost plan according to

Full design of

project by the

architect

Preliminary design by

the engineers

Preparation of cost

Detail consideration on impact of

maintenance and running cost

Complete cost checking
