A construction proposal is a document submitted by contractors or vendors to a potential client outlining the scope of work and estimated cost of a project. It’s a critical step in the process of securing a contract, as it sets the terms for how both parties will manage the project, and serves as a roadmap for how the work should proceed. At its core, a construction proposal is an agreement that details who will do what and how much they will be paid for it. It also plays an important role in protecting both the contractor and the client from confusion, disputes, and potential legal issues during the course of the project.
