As with any profession, a contract for engineering services specifies the terms of agreements, services to be exchanged, deadlines, and estimated costs. It also outlines the specific duties of the project's engineering firm.1 However, as a project progresses, its scope—and thus the engineering firm's duties—can expand. As an engineer, it's important to be aware that taking on duties outside those outlined in your contract may increase your liability.2 To understand how, consider the real-life scenario described below.
Unfortunately, clients commonly use engineers' plans and drawings on subsequent projects without the engineer's permission. Even worse, clients have altered engineers’ plans and drawings before using them in subsequent projects, again without the engineer's approval. Shockingly, clients have even used an engineer's seal and stamp without their authorization.
