Timely procurement is key to a successful project. All members of the EPC team work very closely together to develop detailed specifications, site rules & regulations and commercial terms to ensure all orders meet or exceed performance requirements. Executing purchase orders and / or subcontract agreements and expediting key vendor information (footprints & loads) drive our detail design and installation schedule. We have a full time staff of professional procurement personnel who maintain continuous contacts with suppliers to ensure the most current and cost competitive orders.
