Starting in the nineties, unionized general contractors wanted to look for a way that they could compete in an open market against open-shop contractors.
So what they did—I believe it was in 1989—was write into their collective agreements a construction management clause. It sets out the provisions whereby if they do not form a contractual relationship with a subcontractor, they do not have to abide by the restrictions of that subcontract. The owner, therefore, is bound to the contract.
Basically, with a construction management contract, you hire the services of a construction manager, who is a general contractor, to manage the project for you. He'll prepare all the packages. You might have a separate architect and engineer to draw up the drawings, or sometimes the general contractor will do that. But they will manage the whole process for you, on essentially a contingency basis—so much for your trailer, so much for your secretary, so much for your site supervisor or whatever else. They'll basically manage the whole project for you.
They'll put out the tenders for the subcontractors who will perform all the work on the job, but when the contract is written, the contract is with the government. There may be 20 subcontracts in this package. The direct contractual relationship is between the subcontractor and the government, or the owner.
