    Contract Types

    Construction contracts are sourced in a variety of ways. This includes searching planning databases, being included on tendering lists from employer’s agents etc. and by word of mouth. Depending on the stage JSG is appointed, and depending on the client, several different standard forms of contracts are used.


    Our traditional method is used when a developer has produced all the working drawings specification and schedule of works in order to obtain a (or as close to a) fixed priced contract.

    An accurate cost of build can be produced due to the specific nature of the project. Variation orders and architect's Instructions are required to alter the contract, and these are approved accordingly.


    Within this contract we utilise our own architectural consultant and structural engineer to produce drawings to a specification given by the client.

    This form of turnkey contract enables the developer to mitigate the risk of design onto our firm, however this also enables us to have full control over the methods of construction, which could result in a reduction in costs.


    At JSG Design & Build, we understand that every client has different needs and preferences when it comes to their involvement in the building process.

    That's why we offer a tailored approach to our turnkey services, which means we can work with you to determine the level of involvement you want throughout the design, planning, and construction process.

    We believe in open communication with our clients, and we encourage you to be as involved as you feel comfortable.

    We will keep you informed of progress, provide regular updates, and seek your input and feedback at each stage of the project.

    We commit to a minimum of monthly reporting however the frequency and methodology of reporting is flexible based on client requirements.

    During the design phase, we will work closely with you to ensure that your vision and requirements are incorporated into the plans.

    We will provide regular progress reports and seek your approval at key milestones to ensure that the design meets your expectations.

    Overall, our aim is to make the building process as smooth and stress-free as possible for our clients.

    Whether you want to be involved in every decision or prefer to take a more hands-off approach, we will work with you to ensure that your needs and expectations are met.
