On Chelsea Barracks, can you explain how you obtained “multiple quotations” and then how you assessed them?
On variations, the Contractor issue quotations to undertake the works. This would typically include going out to the market to get prices from subcontractor’s.
I assessed the quotations from the Contractor in accordance with the JCT valuation rules.
What would happen if you are not able to agree a quotation with the contractor?
In my assessments, I always aim to act fairly and reasonably. If I was unable to agree the variation at first, I would look to understand why and to mitigate this dispute. However, if I see my assessment as being fair and reasonable, then my assessment of the works would stand, and it would be for the Contractor to dispute this.
On Confidential Project Infrastructure, what was the cause of delay? Was the Contractor entitled to both time AND money?
The cause of the delay was because the Client’s design team were late in issuing their design to the Contractor.
This constituted a relevant matter, meaning the Contractor was entitled to both time and money, yes.
On Chelsea Barracks Building 8, can you explain why the contractor was entitled to more money for defective works?
This Contract was for the fit-out element. The shell and core had been completed by a contractor a few years before.
The fit-out contractor was allowed time prior to entering the Contract to identify any issues with the Shell & Core that could affect their cost. One of the issues they found was that the slab was out of tolerance.
As the previous Contractor met the requirements for the build, as the slab could have been acceptable if it was 5% out of tolerance, it meant the previous contractor was not liable.
What was your advice to the contractor on Chelsea Barracks Building 8?
The problem was that the quote they submitted used the number bags of screed rather than using NRM.
I advised the Contractor they need to measure in accordance with NRM, as per the Contract. I quantified the overall area, and applied the CSA rate to come to an agreement on the overall cost.
You mention two methods of adjusting for delay - what are they?
1) Take off the number of weeks delay from the amount completed.
2) Add the number of weeks delay to the overall prelims period.
What was your advice to the contractor on Chelsea Barracks Building 6?
That they had made no adjustment to their prelims, and they were valuing on the contract completion date rather than the forecasted completion date. I advised that they had overclaimed for their time based prelims and needed to account for the delay.
