Q

What is the Elemental Unit Method? (Order of Cost Estimating)

A

When the group elements are used to build the budget similar to those used in the elemental cost planning process. This is dependant on the information available, but it forms a frame of reference from which a formal cost plan can be developed.

38
Q

What elements are in the group element ‘2 Superstructure’

A

2.1 Frame
2.2 Upper Floors
2.3 Roof
2.4 Stairs and ramps
2.5 External walls
2.6 Windows and external doors
2.7 Internal walls and partitions
2.8 Internal doors

39
Q

What is included in a unit rate? (Order of Cost Estimating)

A

Materials, labour, plant, sub-contractors prelims.

40
Q

What is excluded from a unit rate? (Order of Cost Estimating)

A

Main contractors OH*P and prelims, design team fees, development costs, risk, inflation.

41
Q

How do you calculate OH&P? (Order of Cost Estimating)

A

Adding it as a percentage to total cost of facilitation works + building works + prelims

42
Q

What kind of cost advice did you provide to your client as the design progressed from RIBA Stage 1 to Stage 4?

A

On Cox Lane I provided the Client with a high level budget at stage 1, preparation & briefing, by using the schedule of accommodation and high level design to prepare a cost per m2 estimate using internal benchmarked data.

As the design progressed to RIBA stages 2 - 4 (Concept Design - Technical Design), project drawings and specifications became available and I used these to compile an elemental cost plan by taking off quantities from the drawings.

43
Q

What level of contingency did you recommend to the Client?

A

Working with the design team, we produced a risk register for the project identifying each of the project risks.

My responsibility was to advise the team on the cost allocation for each risk item.

By pricing the risk register and assigning probability and impact profiles, the contingency allowance for the scheme was calculated.

Cox Lane, Helix, Silbury House

44
Q

How would you advise the client to proceed if the cost plan exceeds the budget?

A

I would analyse the costs to identify where the costs are high in comparison to the cost estimate, and then propose value engineering to the client and design team to look to bring the costs back in line with the initial order of cost estimate.

45
Q

What is meant by the term buildability?

A

Using the contractor’s expertise and knowledge during the design phase. The contractor can advise on the methodology of construction being proposed and discuss the pro’s and con’s.

46
Q

What is a functional unit?

A

A unit of measurement used to represent the prime use of a building. E.g. nr of beds in a hospital, or NIA of retail space.

47
Q

What are the advantages of buildability

A
  • Better programming and sequencing / quick construction time
  • Lower capital costs
  • Improved quality in the finish building performance
48
Q

What items have you typically excluded when producing feasibility cost estimates?

A
  • Professional fees
  • VAT
  • Loose fixtures and fittings
  • Inflation
  • Removal of asbestos
49
Q

Why is VAT excluded?

A

Different client will incur different levels of VAT and sometimes it may not be applicable.

50
Q

51
Q

How do you apply construction inflation?

A

The period from the date of tender return to the mid-point of the construction project.

52
Q

What is design development risk?

A

An allowance for use during the design development phase for risk associated with uncertainties surrounding design development or statutory development

53
Q

What is main contractor’s design development risk?

A

When design liability is transferred to the contractor, it is recommended that an allowance for their design development risk is included in the risk allowance for design development.

54
Q

What is construction risk?

A

A risk allowance for use in the construction process for risks associated with sit conditions, ground conditions, existing services etc.

55
Q

What is employer change risk?

56
Q

What is Employer Other Risk for?

A

A risk allowance for other employer risks such as acceleration, liquidated damages, or special contract arrangements.

57
Q

What is the PTE?

A

The PTE stands for Pre Tender Estimate, and it occurs after the formal cost planning process, it’s the final cost check before tenders are invited.

58
Q

What elements can you expect in a typical cost plan?

A
  • Executive summary
  • Project description, status of cost plan
  • Drawing register
  • Area Schedule
  • Assumptions and exclusions
  • Cost plan
  • Value engineering
  • Reconciliation to demonstrate the amendments made from the previous cost plan

60
Q

Define Cost Control

GIA is measured to the internal face of the perimeter walls, but IPMS2 is measured to the internal extents of the internal dominant face.

65
Q

What is the difference between IPMS3 and NIA?

A

NIA is known as ‘net internal area’ and IPMS3 is known as ‘useable floor area’. IPMS3 includes for areas not included in NIA such as lift lobbies.

measured vertically from the structural floor surface, or to the ceiling if lower

67
