CPM Construction  -
A sequential design-bid-build process, typically delivered under a lump-sum or cost-reimbursable contract, is the traditional method of project delivery, especially for the public sector, where work is awarded to a construction company according to a competitive bidding system.
The client retains an architect or engineer to design the project and to prepare the necessary drawings and specifications.
 After the architect/engineer completes the drawings and issues them for pricing, the client selects the general contractor through a sole source or a competitive bid process.
This method appeals to clients who have the resources and construction experience necessary to independently contract with the architect or engineer and general contractor. While it requires a longer schedule, you maintain greater project control, and may benefit from the reduced risk that is inherent in other project delivery methods.
As the general contractor, CPM provides a confirmed price–after design is complete and before construction begins.
 CPM  executes the project securing the property, providing temporary utilities on site, managing personnel on site, providing site surveying and engineering, inspections ,hiring and coordinating the subcontractors work, monitoring schedules and cash flows, and maintaining accurate records.
