GOT TO STUDY Flashcards
Can you tell me how you believe Covid / Brexit has effected procurement / tendering?
Unknown impact of covid may lead to contractors being more inclined to seek the more management routes and avoid fixed price routes due to:
- unknown impact on inflation & construction costs generally so difficult to price in their costs
- similar for tendering strategies above
How would your two stage tendering option work?
Outputs in 1st and 2nd Stages?
1st stage under PCSA Prelims OHP Programme Designed packages PCSA Fee Target Cost Plan to assess against
2nd Stage to develop S2 to S3/4 to arrive at a Contract Sum
Finalise design
Agree outstanding packages
Rules placed into 2nd stage (min 3 tenderers, open book, evaluation)
Contractor in charge of tender
How did you back up the elements that could produce savings?
Through benchmarking analysis:
I would expect to see:
External Walls @ £260/m2 not £300/m2
Glazing @ £110/m2 not £170/m2
In your documents you have highlighted the advantages/ disadvantages of Steel v Concrete. Could you talk me through some of these?
Steel
Advantages:- Quicker to construct- Recyclable- Strong tensile strength Lighter than concrete
Disadvantages- More volatile pricing - Low compression strength - Low sound/fire resistance - Requires soundproofing
Concrete
Advantages
- High compression strength
- Good noise resistance
- Good fire protection
- Low maintenance
Disadvantages
- Slower to construct
- Need for reinforcement
- High embodied carbon
- Not as square and flat as steel
Are you aware of any renewable technology techniques?
London 0% Carbon Local labour Photo voltaic panels Blue / Green Roof Presence detectors ASHP GSHP
Talk me through the savings you were able to make on the SFS vs Blockwork on the facade? And what other considerations aside from cost?
SFS £750/m2 = £5.6m
Blockwork £550/m2 = £4.4m + 3 months of prelims = £1m = £5.4m
3 month quicker construction led to the client accepting this option.
Impacts on structural were positive with SFS
Concurrent process of fit out / facade
Talk me through the savings you were able to make on the blockwork vs SFS w/steel mesh to the internal walls? And what other considerations aside from cost?
3000m2 of area
SFS
£100/m2 +
£40/m2 for steel mesh = £420k
Blockwork
£50/m2
+ 3wk prelims = £240k (£80k / wk)
Overall £30k difference but client opted for 3 wk quicker construction
Shortage of bricklayers left unknown on costs
How is a steel frame constructed?
Steel columns will be cast into the slab
Installation of universal beams
Beams run across the upper floor area for floor finishes
Purlins to run across the roof
Accessories to fix and tie the frame together
What are the pros and cons of SFS?
Pros Lighter frame Programme benefits Concurrent fit out / facade Prelims savings
Cons
More expensive
Limited suppliers
Fire resistant barrier installed to façade
How did you advise on design efficiencies?
£13m but circa 20% across 8 buildings increase on Net Areas on the projects which would have lead to greater returns on investment for my client
Name some assumptions and exclusions in your cost plan?
ASSUMPTIONS 1Q 2020 Base Date Assumed fit out specification Assumes external works specification Assumed for removal of contaminated material
EXCLUSIONS Professional Fees Inflation Land Costs VAT Impacts of Covid-19 & Brexit
Can you tell me about Modular Construction Pros and Cons?
PROS
Quicker construction
Better quality
More sustainable
CONS Lead in times Lack of cost data Design freeze (no flexibility) Comes at a premium Valuations
How do you assess L&E claims?
Within 28 days of receipt Assess an entitlement to RM Assess the heads of claims Negotiate and Agree with Contractor Instruct
How do you assess EOT Claims?
Notice of extension by contractor citing R.E
12 weeks to assess
Assess overview of the facts
Agree and grant EOT
What considerations should be made when taking out a PCG?
If the Contractors Parent Company was to go insolvent, there would be no action for recourse for the client
How do you assess materials off site?
Listed in Contract
Quantify Insured In the Clients name (to avoid retention of title cls) Vesting certificate Ensure Contractor has paid the supplier Safely stored
What is IPMS 1 2 & 3?
IPMS1 - GEA
Excludes: Temp Mezzanine
IPMS2 - GIA
Excl: Temp Mezzanine
Measures to the IDF
IPMS3 - NIA
Included balconies, internal walls, columns
What planning conditions were relevant to your project?
Section 106 S278 Works (improvement of roads) New build Cafe Employ local labour Section 73a (in event of redesign)
What were the costs above the clients budget?
Windows £300/m2 cheaper than expected
Ext Walls £200/m2 cheaper
Mansard roof not priced which is around £200/m2 more expensive
It seems a tight programme for the 2 stage tendering, given that you finished your S2 Cost Plan was finished at the end of January, could you let out the first stage in 6 weeks?
Utilising my clients framework, I sought to understand if the market believed this would be achievable. The general feedback is that it would have been achievable, however, I informed my clients on the risk that it would be a tight deadline and we’d seek to agree a Target Cost Plan that meets their £55m budget.
