What’s the key difference between the traditional and D&B payment cycle

The D&B payment cycle doesn’t start until the contractor submits their application where’s traditional need to be valued in line with the dates even if an application isn’t submitted

What’s the difference between defined and undefined provisional sums

The contractor is expected to incorporate defined prov sums into their:

Programme
Prelims
OH&P
Design risk

How well did you know this?

Not at all

Perfectly

How do you value prelims if an EoT has been granted but no loss and expense

Divide the prelims budget within the contract sum by the extended programme duration

What does IPMS stand for

International property measurement standards

What does NRM stand for

New rules of measurement

Whats the document which quantities are to be re measured against in a re-measurable contract

Bill of quants

What are the 4 types of valuation method

Stage payment Milestone payment Payment against an activity schedule Valuation of the works done to date on site

What are the pros and cons of stage payments

High predictability of cashflow but low accuracy of works done to date

Pros and cons of milestone payments

High predictability of an amount due upon each milestone but a low predictability of when they become due

Pros and cons of an activity schedule

Provides reasonable predictability of cashflow but only reasonable accuracy of the value of works done to date

Pros and cons of valuation of works done to date

Lowest predictability for cashflow but most accurate for value of works done to date

Describe stage payments

Pre agreed amounts paid at pre set times regardless of progress

Describe milestone payments

Pre agreed amounts are paid upon completion of pre agreed elements

Describe payments against an activity schedule

At pre agreed timescales progress against an activity schedule is monitored and pre-agreed payments are made for activities which have been completed

Who holds the risk of having quantified the scope of work correctly from the contract docs on a standard building contract WITHOUT quants

The contractor

Who holds the risk that a bill of quants are accurate under a standard building contract WITH quants

The Employer

How are errors in the bill of quants dealt with

They are corrected and treated as variations

When will the bill of approx quants be re-measured

Once the design is complete

Who holds responsibility that the approximate bill of quants is accurate

The employer

In terms of valuing change, whats the benefit of having a bill of quants opposed to a priced document (e.g. a CSA)

There is more info for the QS to use for the valuation of variations

How would I get comfortable with the price of a variation

Benchmark the rate against comparable data

What does RFI stand for

Request for information

What does COR stand for

Change order request

Who submits an RFI or COR and what’s the process

Contractor submits I review by measuring against drawings and benchmarking If I agree we tell the client the request is acceptable and ask if they want it instructed If I disagree I query it with the contractor

Who generally controls contingency (excl contingency built into D&B contract sum)

Client

What contract would you expect contingency to be built into the contract sum

D&B

How do you manage and quantify risk

Prepare a risk register

How does a risk register work

Outline the initial risk and score it based on impact and likeliness Outline a mitigation method Re-score based on the mitigation method Comment if the risk is acceptable or not

Give an example of value engineering

Introduce a lesser spec

What does RCA stand for

Reinstatement cost analysis

What does an RCA do

Provides an assessment of the construction costs of building the scheme from the ground up for insurance purposes

What three elements form the build up of a variation cost

Plant, labour and material Additional OH&P Additional Prelims

How would you value a variation if the spec is the same but the quantity is different

Use the rates in the CSA, and re-measure quantity against drawings

How would you value a variation of spec changes but quantity is the same

Use the measurements from the CSA then use rate/ benchmarked rate

What elements have you included in a valuation

Prelims Measured works Variations Materials on/ off site Loss and expense claims Retention

Who physically issues the payment notices on your Leeds scheme

My Director

What documents do you received ahead of issuing your payment notice on Leeds

Contractors application QS valuation (myself) Compliance statements from the design team

Where would you check for the valuation rules

The Valuing Change black book The JCT contract clause 5.6-5.10

How would you value a variation if varied work is not of similar character to work in the CSA (I.e different spec and quantity)

Fair rates and prices shall be used and measurement will be taken from the latest drawings

How would you omit element of the contract sum

Omission will be in accordance with the values in the CSA for such work. If the item of work can’t be clearly identified in the CSA then the employer and contractor need to act fairly in agreeing the value of omission.

What method of valuation is used if work cannot be properly valued by measurement.

Daywork

What schedule of the JCT D&B and Standard Building contract deals with Contractors Quotations for valuing change

Schedule 2

What does schedule 2 of the D&B and standard building contracts contain

Mechanisms that enable the contractor to provide a variation quotation.

What should the Contractors variation quotation include

Value of the adjustment alongside relevant calculations The length of any EoT required The amount of any direct loss and expense A method statement for undertaking the variation.

Is the inclusion of Contractors Quotations for valuations optional?

Yes

Are columns included in the NIA as per IPMS

Yes

How do you deal with valuing prelims in case of delay

Unless it’s a relevant matter, the prelims budget in the CSA is spread across the revised duration.

What would you do if you received a quote from a European supplier

Convert to euros Notify client of potential import tariffs Notify client of potential exchange rates Notify client of potential delivery delays

Give some examples of maintenance work carried out under NRM3

Legionella testing PAT testing

Why was IPMS introduced

It was introduced as a global standard for consistent measurement
