Case Study - Key issue 1 Flashcards
What is the BSA?
Introduced to ensure building and fire safety is managed. New building safety regulator.
In response to Grenfell.
Was the project deemed to be a HRB, if so what is a HRB?
A residential building above 18m’s and/or 7 storeys tall.
At least 2 residential units.
What are the new rules for HRB under the BSA?
All high risk buildings are regulated by the Building Safety Regulator and need to go through a 3 stage gateway process prior to start on site and occupation.
How has BSA and HRB impacted the cost of a project?
Greater requirement for early contractor input increasing PCSA costs.
What was the cost per unit for the PBSA project in the RIBA 3 cost plan?
£17m / £159k per unit
What was included in the budget?
Measured works costs, on costs and inflation. Excluding design team costs and PCSA fees.
What was included in the cost plan to represent a targeted September 2026 go live date?
Tender Inflation- (base TPI - TPI at SoS)/TPI at SOS = inflation factor
Construction inflation - (TPI at SoS - TPI at Midpoint)/ TPI at Midpoint = Inflation factor
What was included in the cost plan to represent the high standard of living?
High amount of amenity space provided.
Allowances for interior finishes.
Allowances for FF&E.
Why did you choose Design & Build as the procurement route?
a) Challenging site so early contractor involvement into the design was required.
b) Potential for earlier start on site due to overlapping.
c) Design risk transfer to the Contractor limiting potential post contract cost increases.
Why does design risk transfer to the contractor limit the potential for cost increases post contract?
a) Once the contract has been let any changes associated with design development the cost is borne with the Contractor whereas for a traditional contract this would be with the client.
When is it appropriate to use a design and build contract?
a) When detailed ER’s have been prepared.
b) When detailed contract provisions arg necessary.
Does a design and build contract give you cost certainty?
How are discrepancies in the ER’s & CP’s dealt with within?
a) If the contractor becomes aware of discrepancies in the ER’s CP’s or Instructions, they have to give notice to the Employer.
b) Contractor notifies of proposed amendment.
c) Employer decides between discrepadcies or accept the contractors proposal.
Contractor must comply with the decision by the Employer without cost to the Employer.
Why was a traditional procurement route and contract not chosen?
a Sequential process therefore overlap between tendering and design and design and construction would not be possible.
b) Outturn cost is dependent on a fully robust design by the clients design team.
How did your cost estimates differ from a cost plan?
How are stakeholder identified?
What changes did the operator propose?
a) Introduction of a Gym
b) Private dining space
c) TV’s to each room
d) Bespoke bathroom pod from a specific supplier
e) Access controls to all lifts and stair doors / openings
F) Luxury vinyl to studios
g) 1800mm wardrobes
h) Walled garden fit out - caravan, AV system, data points, coffee stall.
What was the difference between the RIBA 2 cost plan and the interim-9IBA 3?
a) Approx. £850k
What allowances were made in the cost plan to cover client changes?
b) Overall risk allowance @ 10%
c) Employers change @ 2.5%
How was this risk allowance ascertained?
a) Based on a percentage as there was no risk register at this stage
Why did you decide to do an interim cost plan?
a) There were many changes being proposed and the costs were based on high-level feasibility style information from the design team. Producing the interim RIBA 3 cost plan allowed the design team to provide more detailed design information and for me to demonstrate to the client the overall potential impact of the operator’s requirements.
Why were the operator requirements important to the client?
a) There was an agreement with the Sperator that they could influence the design.
Why was there no allowance for gym in the stage 2 cost plan?
a) There were allowances made for amenity space which comprised of break out and study areas but early on a gym was discounted by the client.
Why did you think increasing the project budget was a reasonable proposal?
a) The client was in acceptance that there were scope changes which were as a direct result of the operator but the operator’s requirements had to be seriously considered.
