A contractor agreed to build a two story garage, but early in the project realized he had made a mistake. He had constructed the foundation footer shorter than the length needed. He advised the owners and proposed a resolution.
A contractor, hired by a developer to perform certain earthwork, priced the job with the idea the he could remove excess fill from the job site and haul it to another project on which he was also working. An easy way to make some money, or so he thought.
You think you have an understanding. So you prepare and sign an agreement with all the key points, and send it to the other side for signature. You even add a provision, asking that the document be signed and returned by a particular date. What if it isn’t; do you still have a deal?
More than midway into a project, two architects were terminated by a college for unsatisfactory performance. The college also alleged that since the architectural partnership had never obtained the requisite certificate of authorization, there was actually no valid contract in place.
Because of the length of time it takes to complete a project, the number of parties involved, and the general unpredictable nature of construction work, it is rare that a contract for such work remains unchanged from start to finish.
