MC Case Study Flashcards
What did you mean by the client being risk averse to safety and value?
They wanted the best solution to provide safety against the spread of fire and to provide evidence of this to produce in the occurence of selling the property.
What fire stopping works were being suggested and by whom?
Subbie: strip out existing seal and replace with a certified solution where possible and batt and mastic when not
Contractor: Provide a seal over the existing
What fire certification was being sought?
The client wanted a 60min firestopping certificate
Subcontractor were third party approved by ASFP (Association for Specialist Fire Stopping) and BM-Trada Q Mark Scheme for Fire Stopping
Meant they could issue a certificate if tested and certified methods were used.
What legislation and dcouments govern fire protection in a building?
The Fire Safety Act
Approved Document B: Fire Safety
CDM regulations
The building safety act
Are you aware of any fire stopping certification?
Certification for approved installers includes:
FIRAS Certification Scheme
IFC Certification
BM-Trada Q Mark Scheme
Are you aware of any documents you can refer to for the tendering process?
JCT Tendering Note
RICS Tendering strategies
RICS Procurement Strategy and Selection
Was Option B instructed?
Yes, it was instruted under a contract administrators instruction, confirming the scope and cost of the works.
The main contractor then engaged the specialist as a domestic subcontractor under themian contract to carry out the works.
How did you get to a value for money situation?
The works were quoted with an elemental breakdown.
This meant I could benchmark costs for the stip out works, market test the products/materials being quoted and sense check the overall cost vs the expected duration to assess if the effective day rate was reasonable.
As part of this process we were able to gain a small reduction on the strip out works by bechmarking against the main contractors CSA rates which the subcontractor agreed to.
In general, how reliable do you find prices when you market test?
Generally the costs returned are a reflection of the infomrmtion I have at the time:
Good/Detailed: Accurate
Assummed elements: Useful, we would usually add an assumption or uplift for risk
Outline: Guidence only, if attempt at all.
What was the insulation used on the project? Why was it taped and jointed?
The insulationused was a Celotex PIR insulation board.
The boards are jointed to create a continous layer of insulation and prevent air leakage which helps to reuce energy loss
How fire proof is that insulation?
Poor, I would have to refer to the data sheet but from memory it was euroclass F and considered combustible.
How was the common area forestopping works co-ordinated.
The line of deliniation was the boundary of the apartment.
Where works were being carried out to stair core entrances, the specialist and contractor held seperate meetings to coordinate work and this resulted in their engagement for anciliary works around entrance doors. This relationship was one of the reasons they were invited to participate in the formation of firestopping options as part of this key issue.
What are the pros and cons of working with a client with past development experiance?
Pros: They are aware of the risks invoved with maintaining control over design and the time and cost implications client led change can have on a project.
Cons: As they are still not construction specialists, they may incorrectly extrapolate expereinces from past projects to provide unrealistic expectations.
How did you manage avoiding risks associated with change?
I set up a change control procedure to manage client change.
What advice did you give to the client regarding the timescales of each procurement option?
Single stage would be the longest because of the inherent sequencing of works. ie full design before tender and construction
Two stage would have an overall shorter duration as design and construciton could overlap, but the tendering process was longer as in two stages.
D&B route could potentially be the quickest and design and construciton coudl overlap, however as the client wanted control over design, the development of robust ER’s before tender would also reduce this benefit
