Benefits of Using a Main Contractor
It reduces the responsibility and risk of managing the project yourself, providing a single point of contact for any issues that arise. However, this also means less control over the project, and complications may occur if the contractor goes bankrupt. While builders are often very efficient and focused on speed, it is your responsibility to ensure that quality is not compromised.
Key Tasks When Using a Main Contractor
Finding the Right Builder
The best approach to finding a reliable main contractor is through a formal tendering process. A quantity surveyor can be invaluable during this stage, helping to prepare tender documents, recommending builders to invite, and interpreting the quotes you receive. This ensures you get a clear understanding of the costs and scope of the project. Your architectural designer may also recommend builders they’ve successfully worked with before. Make sure any contractor you consider has the necessary health and safety credentials and full insurance coverage for the project.
Evaluating Builders
Before selecting a contractor, visit some of their recent projects and speak with previous clients if possible. A key point to check is whether the same sub-contractors who worked on their prior projects will be involved in yours. A construction contract that lists all the sub-contractors can be helpful in ensuring consistency.
Setting Up a Contract
Once you've selected a contractor, it’s crucial to establish a formal contract. This document should clearly define the responsibilities of each party, based on a detailed set of construction drawings and a bill of quantities prepared during the tendering stage. Using plain-language small works contracts helps clarify all aspects of the project, including who is responsible for what, costs, payment schedules, and how to handle changes or disputes. This ensures both parties are on the same page and minimizes the risk of surprises during the build.
