Professional Practice: Guideline for Quantity Surveyor Chapter 2

D) Design Development

While the Concept stage was only a general approach on a design, the design
development will be more detail on it. The design team will identify the detail
information from various sources to full fill the client needs and the regulation by

the local authority. It is a process of completing the project brief and prepares the
certain proposal including item below:

 Design approach
 Method of Construction

 Specification
 Building amenity

 Building structure
 Cost

The information from the project brief is still needed at this stage. Sufficient
information is important because it can avoid uncertainty and to ease the design
team completing the design and select the quality of material which are suitable

and follow the client needs and client requirements.
After this stage the project brief is no longer can be amend. Several

choices of design and construction method to be consider and QS will prepare
the estimate cost that shall include initial cost and future cost such as
maintenance cost.

The engineer will prepare the structural design. The architect design
(drawing) and engineer design (drawing) are different to each other and both play
a major role in construction. Engineer will prepare the engineering structural

drawing base on calculated load to ensure the building can be built without any
problem.
For servicers engineer (mechanical and electrical), the job scope are

different. Services engineer is responsible to design all the building services and
facilities such lift, escalator, cold and hot water system, fire system, electrical, air

conditioning, garbage disposal system, and etc. Client agreement is important
before the architect can apply and getting approval from the local authority.
In this stage, the quantity survey job become more detail and its cover all area of

costing (Cost Planning). The information given by the architect and engineer are
