In a lump-sum contract, which party remains obligated to complete the work regardless of challenges faced?

In a lump-sum contract, the contractor is responsible for completing the work as outlined in the agreement, regardless of any challenges or unforeseen circumstances that may arise during the project. This means that once the contractor agrees to the price and terms of the contract, they accept the obligation to deliver the project for that fixed amount.

This contractual structure provides a clear scope of work and cost for the project owner, which helps in budgeting and financial planning. However, it also places the burden on the contractor to manage risks, materials, labor, and potential obstacles without additional compensation beyond the agreed sum.

Other parties mentioned, like the project owner, subcontractor, or project manager, do not hold this primary responsibility; their roles may vary in terms of oversight, support, or specialized tasks within the project, but it is ultimately the contractor who must ensure that the project is completed, adhering to the terms of the lump-sum contract.
