Which building contract to use?

marlow architectural contracts

CHP drawings and documents are normally suitable as the main contract documents between the client and builder in securing the works at an agreed price over an agreed period of time.  Using this system usually requires a simple exchange of letters providing the following information:-

1 - Reference to the builders quotation figure / tender return form.

2 - Start date and contract period.

3 - Agreed payment terms (stage payments and the amounts).

4 - Agreed retention sum and terms for pay back after a period for latent defects.

5 - Any other reference to alterations, extras or omissions.

6 - Supply of proof of builders insurances.

All other relevant schedules and terms are within the specification manuals that CHP provides as part of his building design package.


There are additional formal building contracts that can be used alongside the approved plans and specifications such as:-

1 - JCT minor or intermediate works (fee required to JCT).

2 - Federation of Master Builders (FMB) have their own and your builder does not have to be a member to use them (free to use).

3 - National Home Builders Council (NHBC)

4 - NEC3 engineering and construction contract (fee required to ICE publisher)

4 - Other (privately made contract)

It is probable that the use of a formal building contract will provide you with additional protection BUT only if you understand the wording and processes required should things start to go wrong. There is also a risk that the terms or clauses may vary between CHP documents and any of the 'off the shelf' formal building contracts mentioned above which could cause confusion.

Overloading the 'wordiness' of the terms and contract can also have the adverse effect of your tendering builders loading the price or simply refusing to quote (for the added complications) so you do need to find a balance.

Our advise would be to assess the quality of information that CHP has provided for your particular scheme after Building Regulations approval and decide for yourself whether or not you require any additional form of standard building contract just prior to tender.




There are also various ways of managing the works.  All of CHP documents assumes that you will be engaging a main contractor or builder in the normal way on a fixed price quotation.

There are two other alternative methods which are described as  follows:-

Management Contracting

GENERALLY:-

As part of the design team, a management contractor usually charges a fee for managing construction work, whilst not actually carrying out the work itself. The method has been also called a “fee system” of contracting. The management contractor will provide the “preliminary” services such as cranage, hoisting and lifting facilities, scaffolding, welfare accommodation, lighting, security, power and management staff.

The management contractor’s responsibilities are often to ensure that:

  • the design, together with the bill of quantities, specification and other documentation for the project, is completed in order to ensure a successful programme
  • subcontractors are appointed to meet the programme and that their work is in accordance with the specification
  • when the time comes all remedial work is expeditiously carried out and that the completed project is handed over to the employer.
RELEVANT POINTS:- 

1. The management contractor is not responsible for the final cost, but it is incumbent upon him to work with the design team and to use his best endeavours to try and ensure that the project is completed on time and within the estimated cost.

 

 

Construction Management

GENERALLY:-

An alternative to Management Contracting, in Construction Management the Client engages all the specialist contractors directly. In this form, it is usual to engage an additional skilled professional person as a Construction Manager to contribute to the management of the process.

The Client is normally used to construction work and may well be expert and knowledgeable.

There is a JCT standard form of contract available for this method of procurement.

RELEVANT POINTS:- 

1. Careful selection of a contractor and the production of a fair contract, backed up with adequate information is just part of ensuring a successful project and avoiding disputes over building work. The contractor should be regarded as a team member, not as an adversary. 

 

The above two alternatives are usually only applicable to clients who have some form of building knowledge and the time to get involved with the build on a day to day basis.
