Coordination drawings are part of a contractor prepared portfolio of documents used by a contractor to support a claim of how proposed work is to be coordinated and performed on a contracted project. Works in the Coordination Drawing portfolio are not to be deemed as contract documents. These documents come into existence when architecture and engineering consulting firms agree to develop plans for a given project. These plans should include anticipated coordination efforts of subcontractors. When complete, each tradesman should get a copy of the coordination drawings so everyone participating in the project is aware of of the role each of the other contractors play in the project so as to avoid time delays and conflicts. This kind of coordination is obsolutely critical to the overall success of any planned commercial building project.
Coordination plans in the construction trade at one time were simply used to neutralize conflicts relating to the use of space within the layout of the construction site, but today, these plans are often enhanced to provide a framework for understanding exactly where equipment needs to be deployed as well as such services as duct work, plumbing pipes, and conduit systems that carry utility lines. The risk of running into interference with respect to timing and access increases as projects become more complex, and problems are most likely to crop up when a building design incorporates a high degree of mechanical (elevators), electric, and water usage. The elimination of coordination conflicts by way of adequate planning is the only reliable way to ensure that projects can be completed on time and within budget.
