They are responsible for reviewing bids, proposals, and tender documents, as well as considering the cost of the project. Additionally, they work closely with the architect, engineer, and client to ensure that the building meets all necessary codes, is completed on time, and that all parties are kept informed of the progress. Overall, the general contractor is essential in ensuring the successful and efficient completion of a construction project.
