Ensuring the quality of the build process

Turnkey projects

Most of what is set out below will not apply if a contractor is simply supplying the CLT with completed homes. You should however still have regard to the need to a handover inspection and agree what arrangements there will be for returning to deal with contract defects for a period of 6-12 months.

If the homes are not yet built, you could also require some involvement in inspecting the work as it proceeds.

Managing the contract on site

Once you have your professional team in place they will draw up the building contract. This is usually the role of the quantity surveyor or the employer’s agent but the architect will in both cases contribute the drawings and specification which you will need to have examined and agreed carefully, possibly by a subgroup of the CLT. The contract determines the build quality either by specifying a standard or by specifying particular suppliers although the latter may have problems for cost or potential delay.

Once the contract is signed, your professional advisers will organise a monthly meeting on site to monitor progress, agree the proportion of the contract due for payment, answer any queries, help the builder overcome difficulties such as supply problems and also observe and check on the build quality. In agreeing the “certificate”, the sum of money due, your team are also accepting that the building is going up in accordance with the contract so this is also the time when, if the build quality is inadequate, they will refuse payment for poor work and require it to be re-done or repaired. With a conventional contract, the architect deals with design issues, build quality and variations and the QS certifies the value of the work. With a design and build contract, the employer’s agent fulfils all the functions but the architect employed by the contractor will also be there and has a professional responsibility to ensure quality.

Building regulations inspections will also be taking place which are a statutory requirement to ensure minimum build quality.

It is usual for payment to be demanded within 2 weeks after the certificate is issued and it is very important to smaller contractors that this is paid promptly as they in turn will be on a tight cash flow, probably with an overdraft arrangement, to pay suppliers, subcontractors and direct employees. You should make absolutely sure you have set up arrangements with your development finance provider so you can pay these monthly certificates on time.

Contract management nearly always demands both firmness and tact from the professionals as “build quality” is not an absolute. The monthly site visits and meetings are important for several reasons therefore and the CLT may itself want to be represented.

On large contracts, clients may employ a clerk of works to provide a permanent presence on site and ensure build quality. This will not normally be necessary - or cost-effective - on a small scheme.

If progress on site falls behind the forecast rate of build, the professional team will issue warnings and in extreme cases have the right to “determine” the contract. The same thing happens if the contractor goes bankrupt. Either is costly as the retention is rarely enough to cover the extra cost of completion with a new contractor. A performance bond, providing, say, up to 10% of the contract sum in these circumstances is a form of insurance you could take out against this eventuality.

The contractor should have liability to insure the site and the building work under the contract. From the start date any site liability insurance you have taken out could be suspended but you may need to consult your insurance broker to check there are no gaps in cover.

Handover

When the scheme is nearing completion, the contractor will arrange to meet with the professional team to agree whether it meets the required build standard and generally to agree a list of the works that must be completed (“snagging”) for a handover of the building to be agreed. A date is then set for a handover by which date these works should have been completed. Your professional team will attend this visit and carry out an inspection of the building and it would be usual for you as client to attend this inspection as well, asking your professional adviser about any aspects of the build you are unsure about which either he/she will then raise with the contractor or (try to) explain to you why the item is acceptable. The snagging list will be checked for completion.

Under a normal contract a “certificate of practical completion” is then issued or under a design and build contract there is a less formal but equivalent procedure. In either case you take possession of the building.

From this date the building becomes your insurance liability again.

Defects liability

There is a period of time after practical completion in which the client (the CLT) is able to require the contractor to return to site to correct any omissions or defective works contained in the original works contract. The contractor will not be liable for any defects incurred which are not related to the contract. A typical defects liability period is12 months or it may be 6 months on all items except mechanical and electrical plant which should always have 12 months liability.

A “retention” is kept back from the monthly certificated payments which is held by the CLT as client against the requirement to remedy defects. When each defects liability period comes to an end, a final inspection will be held with the professional team, contractor and CLT walking through all the homes to agree that all defects have been dealt with. Upon correction of the defects, the contractor administrator or Employer’s Agent will issue a further statement confirming the defects have been satisfactorily dealt with and saying that the retention should be released by the CLT to the contractor.

Your cash flow forecast will show this retention held and then released at the end of the defects period when the homes are already occupied. You will need to agree with your funders how this is to be dealt with: they either advance these funds at the end of the defects liability period or, more simply, advance to the CLT the sum due to the contractor including the retention which the CLT will hold until it is certified for release.

It is usual also to have a 10 year guarantee on the home issued by National House Building Council, Zurich, Premium or BuildZone. This of course also relates to defects, not maintenance.

Claims and delays

Under a conventional building contract, the contractor will have the right to claim for extra costs which were not properly or fully specified in the tender documents or which arise from instructions given by the contract manager. With a design and build contract this can be avoided as the architect is employed by the contractor and any omissions or incomplete descriptions are the design and build contractor’s responsibility. The exception would be where the CLT as client has made a new request after the contract is signed – something you should avoid doing by making sure you have specified in he contract documents all those aspects of the scheme where you wish to control the equipment or materials used or the method of building.

Where delays arise because of additional instructions or because equipment specified in the contract cannot be obtained in a timely fashion, the contractor may ask for extensions of time to complete the work. These in turn give rise to costs which he/she can claim.

On the CLT’s side, the contract will contain a sum for “liquidated and ascertained damages” which are the actual weekly costs the CLT will incur from any delay in completion (normally the weekly interest cost or it could be the weekly loss of rent if this is more). These are deducted from the certificates due if the contract completion has been delayed.

Some larger contractors have special legal departments who appear to be there solely to look for opportunities to make claims. When selecting and obtaining references for your contractors, you might ask the referees if any claims were made under the contract. Generally your aspiration will be to find and work with contractors who see themselves as partners so that both sides work to resolve any disputes and problems jointly as they arise.
