What are the typical roles and responsibilities of the CA?
The contract administrator is the individual responsible for administering the construction contract in an honest and impartial manner.
Generally, the role includes:
Also known as design-bid-build. This is where the client appoints consultants to design the development and then a contractor is appointed to construct the works (although JCT contracts provide for design of specific parts of the works to be carried out by the contractor). The contractor is usually selected by competitive tender, but sometimes negotiation.
This is where the main contractor is appointed to design, plan, organise, and construction the works to the employer’s requirements. The employer gives the tenderers the ‘Employer’s Requirements’ and the contractors respond with the ‘Contractor’s Proposals’, which include the price for the works.

It is the nature of the works which should dictate contract selection. Suited to small works but no guidance is provided on the value. Basic construction with simple nature.
Minor Works with contractor’s design (MWD). Used where the contractor is responsible for designing specific parts of the works.
Minor Works Sub-Contract with sub-contractor’s design is for use when the main contract is the Minor Works Building Contract with contractor’s design, and where the sub-contractor is to design all or a part of the sub-contract works.

Only if the works are to be procured under the Design and Build Procurement route.
A provisional sum is an estimated allowance that is inserted into tender documents for a specific element of the works that is not yet defined in enough detail for tenderers to accurately price.
A provisional sum can be categorised as ‘defined’ or ‘undefined’.
Defined provisional sums are those which have been described in sufficient detail that the contractor is expected to have made allowance for them in their programming, planning and pricing preliminaries. The work may not have been completely designed but the following information may be known:
Undefined provisional sums are less well described and so the contractor cannot be expected to make allowance for them in their programming, planning, and pricing preliminaries.
I would review:
An allowance included in the tender documents for the supply of work or materials to be provided by a sub-contractor or supplier that will be nominated by the client.
The main contractor is entitled to add mark up and attendance costs to the allowance. If the actual costs then turn out to be higher, the contract sum is increased, and if the actual cost is lower, the contract sum is reduced.
A subcontractor that is selected by the client to carry out an element of the works and one that is imposed on the main contractor following appointment. The mechanism for nominating is an instruction in relation to a prime cost sum to which the main contractor is entitled to add a mark-up and attendance costs
Contract instructions can only be issued by the Contract Administrator. They be written or oral, but the instruction has no effect until it has been confirmed in writing.
Contractor must comply ‘forthwith’; that is, immediately and without delay.
The CA must issue a 7-day notice if the contractor fails to comply with an instruction. If the contractor still fails to comply after the 7-day period, the Employer may employ a third party to do the works and the main contractor will be liable for the costs.
A variation is an alteration to the scope of works in a construction contract in the form of an addition, substitution, or omission from the original scope of works.
Variations are often valued based on the rates and prices provided by the contractor in their tender, provided the work is of a similar nature and carried out in similar conditions. If similar types of works cannot be found in the contract documents, then fair valuation of the contractor’s direct costs, overheads, and profit is necessary.
Payment Certificates must state the sum the CA considers having (i) been due at the payment Due Date and (ii) the basis on which that sum is calculated. You would also expect the contract sum, gross valuation, retention, previous amount certified, and net amount payable in figures and words
The contractor can make an application for payment which will become the payment notice by default if there is no Payment Certificate issued within 5 days of the Due Date.
