How long was the PCSA period?
6 weeks
What activities were the Contractor appointed to do during the PCSA?
Undertake surveys, provide a fixed costs for the works, advise on buildability for the works?
What is buildability?
The ability and ease with which a project can be built efficiently in terms of time, cost and quality
What aspects did the Contractor advise on in terms of buildability?
MEP coordination – design was being taken to RIBA Stage 04. Used surveys from the existing building to help coordinate elements like space-heating based on the architectural design
1.Commented on design based on experience and site surveys
2. Suggest changing bulkhead / partition details – aware of pipework, clashes
3. Help to meet acoustic requirements
Was Option 02 a viable option?
Reviewed because it was the most competitive option, project was already in delay and so the review was to see how much it was delayed.
Was Option 03 a viable option?
Yes, because it looked to achieve all the client requirements

Additional 2nr weeks to select preferred contractor and to negotiate the contract
You mention MEP resilience as a key change, what did this include?
This was the addition of a UPS to facilitate the trading floors

£3k per linear meter
Manifestation was £200 per linear meter
What was the total saving from VE?
£711,000
What is value engineering?
Structured process of analysis alternative methods/materials without detriment to function or quality
How does this differ to value management?
Value management is a more holistic approach to identify opportunities to increase value
