General Contractor

Definition

A general contractor (GC) is the primary party responsible for on-site management of a construction project. The GC holds the main contract with the property owner, hires and coordinates specialty subcontractors, and is responsible for scheduling, safety, and on-site execution. In the traditional delivery model, the homeowner separately hires an architect to create plans, then the GC bids on and executes those plans. The GC does not typically provide design, engineering, or permitting services as part of their standard scope, those relationships are the homeowner’s responsibility to manage.

Frequently Asked Questions

What is the difference between a general contractor and a design-build firm?

A general contractor typically manages the construction phase only, working from plans provided by a separately hired architect. The homeowner manages two contracts and two relationships. A design-build firm like Center Island Contracting handles both design and construction under a single contract, with one point of contact and one point of accountability for the entire project from concept through completion.

Why General Contractor Matters

Understanding what a general contractor does, and does not do, helps Long Island homeowners make informed hiring decisions. A traditional GC arrangement requires the homeowner to manage the relationship between architect and contractor, which creates accountability gaps, budget surprises, and timeline delays when the two parties disagree. Knowing the limits of a GC scope is the first step in evaluating whether design-build is a better fit for your project.
