A construction management contract is a contract that is entered into between a management firm or consulting agency and the owners of a project. The management contractor then becomes the entity that coordinates all the phases of constructing the project for the owners. The management contractor obtains contracts from general contractors or subcontractors to do the actual building of the project The management contractor also acts as liaison between the designers / architects, the owners, and the builders. Advising all of them as to the most efficient, and economical, methods, supplies, and procedures, to complete the project within the budgets and guidelines desired by the owner.
A general contractors contract is entered into by the contractor and the owner to do the actual building of a structure. This may be done through a management company / consulting firm, or with the owner them self. Either way the contract is with the owner and not with the management company. The management company ensures that all contracts are executed properly and in the best interest of the owners.
As an example:
Corporation X wants to build another ten of there popular widget stores. They are not familiar with the contractors, codes, suppliers etc. in all the towns they wish to have the new stores built in.
They then contract with Know-em-all consulting to manage the construction of the new stores. Know-em-all then coordinates the building of the stores by local contractors, ensures that quality work is being done and done properly, schedules delivery of supplies, Schedules sub contractors and keeps the project within the time frame and budgetary limits as set by Corporation X.
I think that this is what you are asking. As I stated before I have never been in upper management nor do I have a degree in busness. So if this is not what you are looking for let me know and Ill hit the books again.
