Quantification and Costing Flashcards
Why were the New RUles of Measurement introduced
/ The previous standard method of measurement SMM7 was purely designed for the production of BOQ
/ This resulted in the lack of guidance and uniformity around preparing cost estimates and cost plans when using SMM7
/ The NRM was introduced to provide a common and consistent basis for the production of order of cost estimates
What is the Structure of NRM 1
/ Part 1 - General introduction
/ Part 2 - Measurement rules for the production of order of cost estimates
/ Part 3 - Measurement rules for the productions of elemental cost plans
/ Part 4 - Tabulated rules of measurement
When should you use NRM
/ The NRM provides common and consistent basis for the production of order of cost estimates and cost plans
/ Provides confidence to employers
/ If negligence claim is brought NRM is best practice
What is NRM 1
Order of Cost Estimating and elemental cost planning
What is GEA
Gross external Area
What is GIA
Gross internal area
What do you measure in accordance with
/ NRM if a building project
/ CESMM if a civils based project
How would you measure steelwork in NRM 2
I would cross check the copy of NRM 2 for the correct guidance and measure in accordance the their measurement rule
What is the purpose of a BoQ
/ The purpose of a BOQ is to provide the estimator with an accurate picture of the scope of works and to provide a common and consistent basis for pricing
/ Following receipt of tender submissions, the BOQ also forms the basis for tender analysis through like for like tender
/ Basis for the valuation rules
How would you prepare a BOQ
/ I would meet with the design team to establish if we have the information
/ I would compile all necessary documents - drawings, specifications, drawing registers etc
/ Check if sufficient information is present
/ agree a method of measurement
/ Commence take off and work from the substructure upwards
How would you structure a BOQ
In accordance to the elemental breakdown sturucture under NRM 2
/ Prelims
/ Facilitating works
/ Sub structure
Super
etc etc
What are included in prelim costs
/ Site setup
/ Management and supervision
/ Insurances
/ Task lighting
/ Protection
If a bill rate was blatantly wrong how could this be resolved
works would be valued in agreement to the contract
if signed into the the contract then would have to be adhered to
If an item is missed from the BOQ how would you deal with it
Check if it is in the contract documents and should have been included
/ if not then see if still needed
/ Treat as a variation
What is a provisional sum
A provisions sum is an allowance included in the bill for works to be carried out where the extent and design of the work is unknown.
