Approximate bills

Question 1

Where does the risk lie with an approximate bill?

Answer 1

Quantity - the Client
Price - the Contractor

Question 2

Why was an approximate bill used over a CSA?

Answer 2

• Allowed for detail breakdown and specification of items
• Provides a consistent basis for assessing tender returns (all the same quantities)
• The risk to the contractor of a CSA would be too great or lead to inefficient returns

Question 3

What is the benefit of a measurable contract?

Answer 3

• Enables start on site earlier
• Gives the best price possible as the Contractor doesn’t need to price risk into their rates

Question 4

How are valuations undertaken

Answer 4

• An accurate value of works must be included under a valuation
• On site materials can be included so long as they aren’t there prematurely

Question 5

Do changes to approximate quantities need to be instructed?

Answer 5

only if the sum allowed for within the bill is not reasonably accurate, or if the architect wishes to instruct drawings that have defined quantities

Question 6

When are quantities remeasured under an approximate bill

Answer 6

during valuations the actual amount of work done must be valued.
