In-Depth Information
The contractor's appointed project manager had been part of the tender team
and directly involved in all the tender negotiations. He was therefore appointed as
the “bid manager” to lead the value engineering proposals and present the final bid
proposals to the client's team.
The contractor value engineered the tender to incorporate the following
proposals:
●
Proposal 1 - Revised foundation type to eliminate the CFA piling on the office
block.
●
Proposal 2 - Considerations of the steelwork design for the office block
●
and transfer floor.
●
Proposal 3 - Alternative system of external wall cladding.
●
Proposal 4 - Consideration of alternative crainage methods for the erection of the
steel and precast frames.
Proposal 1 - alternative solution to the foundations to the office block
The original proposals specified the installation of in-situ concrete CFA bored piles
with pile caps and ground beams supporting a 300 mm thick in-situ ground floor
slab for both the office block and the hotel building.
Alternative proposals involved stabilising the ground to the office block area
using the Bullivant NRG dynamic compaction process. This would enable simple pad
foundations to be designed to support the office structure. The ground floor slab
would correspondingly be reduced in thickness (from 300 mm to 150 mm) thereby
offering further savings.)
Proposal 2 - redesign the steelwork of the office block and the transfer
floor of the hotel block
A redesign of the steelwork resulted in savings over the original design.
Proposal 3 - alternative solution to the external envelope cladding
Original proposals were to provide a composite concrete wall panel to the external
elevations. The concrete facade panel was to incorporate blue brick facings, cast on
at the manufacturing stage. This would eliminate the need for an external scaffold
provision.
