SUMMARY
Proper planning is usually important as far as building and construction is concerned. The client
however must remain consultative enough with the relevant experts including Quantity
Surveyors so as to ensure that which option is taken, the project will incur less cost and be viable
at the same time. In this particular paper a client has been properly taken through the case
scenario of varying parameters of the design before a specific option was selected. The client
was faced with two options. Option 1 was to involve construction of a two-storey office which
was to accommodate a meeting room and a reception hall on the ground floor with office places,
a kitchenette and toilet facilities on each floor. Besides, there was to be an allocation for the car
parking onsite for staff and visitors. Members of the public were to have additional gym on site
fr their utility although this was to be at a cost. In option 2, there was a case of three-story
building housing a reception hall and meeting room on the ground floor, office spaces,
kitchenette and toilet facilities over the first floor but gym was to be located on the second floor.
An approach of cost-benefit analysis has been used while considering the weighing parameters to
decide on the better option. The process of option weighting has been has slightly placed option
2 above option 1.

INTRODUCTION
The concept of Constructability has been used as an approach of linking the construction and
design process and has the potential of time and cost saving which are crucial factors in the
completion of construction projects. It is the primary responsibility of all the project stakeholders
including contractors, designers and owners to improve the Constructability. However, it is
important to note that the client has the most authority in the enforcement of Constructability
implementation. The owners of the project must be fully aware of the decisions which form part
of the planning in the initial stages which are usually difficult to subject to changes once the
process of construction has been started. The Constructability input method used was actually
determined by the selection project by the owners. The involvement of the construction experts’
particular surveyors and contractors assist in the identification of the possible challenges early
enough so that necessary adjustments can be made hence effective performance of the project
(Kabaya et al.2019).
OBJECTIVES
The primary objective of this particular report to offer pieces of technical advice to the client
faced with two available options for the redevelopment a sloping site which was formerly used
for the battery manufacturing plant.

METHODOLOGY
Quantity surveyors are therefore expected to provide precise estimates for the projects
considering the available terms and conditions set the client. The instruction or pieces of advice
given to the client should consider the prevailing environmental and geological characteristics of
the site. In this particular case, the client is exposed to at least two viable options. However, it is
expected that proper enlighten is given to the client so that he/she can make an informed
decision. These options included:
Option 1
A two-storey office building:
 This will be expected to effectively accommodate a meeting room and a reception hall on
the ground floor.
 It will have office space, a kitchenette as well as facilities of the toilet on each and every
floor.
 It will have an onsite car park for visitors and staff
 A state-of-the-art gym for use by members of the public and this will be generating extra
revenue

Option 2
A three-storey building:
 Has only meeting room and reception hall located on the ground floor
 First floor has toilet facilities, office spaces and kitchenette.
 Second floor has the gym
 NB: This will lead to smaller footprint as well as increasing the area of parking for the
customers, staff and visitors.
