While some industrial construction companies specialize only in industrial construction maintenance, or industrial construction installation, some industrial contracting companies employ experienced industrial installers, maintenance contractors, and designers. Whether it's a warehouse or a large plant, industrial construction companies are often chosen on how well their specific skills match the project at hand. Sometimes industrial construction companies are chosen because they offer all of the services that are needed.
When "designers" and industrial maintenance contractors are found within a single construction firm, this is called none other than a "design/build" company. This "in house" group of contractors and engineers with special skills allows the project to get started more efficiently, as all the trade specialties know one another, and have worked together on projects in the past. With these types of industrial construction firms, the client may offer a "design build" where the contracting company is given a set of guidelines by the client, and is expected to construct a structure or mechanism based on that. Still, when it comes to industrial design, many clients prefer to have one main designer, and then hire separate sub contractors for the rest of the work. Depending on the nature of the project, sometimes many different trades are needed to adequately meet the demands of the industrial construction project, as well as government requirements.
