Carter Jonas’ approach to contract administration

At Carter Jonas we have a highly experienced team of professionals that design and run building projects including alterations, conversions, refurbishments, and new builds.

We offer a full design and contract administration service for commercial and residential clients. We work closely and collaboratively with the project team from initial feasibility through to final completion in an impartial and unbiased professional manner. Our talented in-house design team are experts in providing guidance on materials and are focused on developing creative solutions based on client interests.

We are experienced in producing comprehensive specifications of work in the precontract stage that comply with building regulations and professional standards. Our architects and CAD technicians can assist with obtaining planning and building regulations approval by liaising with Local Authorities and by producing high quality drawings turning the project brief into a realisation. We are also able to assist external design teams if required.

After the initial design stage, our contract administrators will lead a formal and thorough tendering process. We can advise on procurement options, the suitability of various forms of construction contract, contract conditions and compile the tender package before inviting contractors to tender. We only invite trusted and qualified contractors to tender for the works and upon receiving the tender returns we will undertake an analysis and make recommendations. If necessary, we will also perform a value engineering exercise should the tender costs exceed the budget, before appointing a contractor and preparing the contract documents.

Once a project is underway, on-site monitoring of quality and progress will form a key component of our work as contract administrator and we will continue to anticipate and mitigate project risks as the project progresses. We chair regular project meetings, certify payments to the contractor, issue the necessary contract instructions and finally administer practical completion and agree the final account with the contractor. To safeguard our client’s interest, we will re-visit the property post construction and arrange for any contractor’s defects to be addressed before certifying the release of the retention monies to the contractor.

In summary, our design and contract administration service includes:

  • Pre-contract
