Question 3

In QCCW, you mention a cost plan - what was the total estimated costs for this? Some of the works categories? Costs including measurement units? How obtain costs from BCIS, Spons, in-house data on these? How did you go about obtaining quotes from several suppliers (did you estimate possible costs in advance?).

Answer 3

Cost estimate (where obtain rates/costs):
Steel - expensive and fluctuates! Check latest market data (£/tonne)
Acoustic partition - quote!
Flat roof - in house
Curtain walling - in house
Finishes - in house
M&E - GIA rate (rate from in house)
Foundations - in house

Obtaining quotes from suppliers (and preparing for anticipation of costs):
Demolition
Acoustic partition

Details on Acoustic Partitions:
Building Regulation Standards: Fire safety (B) short (30 minutes), medium (60 minutes) or long (120 minutes). ; sound insulation (E) The requirement for wall soundproofing of airborne sound pollution in purpose-built dwellings is 45 dB. The requirement for floors and ceilings in purpose-built dwellings of airborne sound also sits at 45 dB. However, there is also a requirement of 62 dB for impact sound (such as walking on floorboards).; structural ability (A) - structural engineer??.
