As Preconstruction Manager, Darren Draper develops highly accurate full-scope estimates at all document levels, including order of magnitude, conceptual, schematic, design development, construction, and bid documents. His responsibilities encompass conceptual estimates, quantity takeoffs, pricing elements, labor and construction equipment costs, requisitions for material purchases, competitive trade bids, job cost budgets, and lead procurement.

Darren ensures that all design efforts reduce ambiguities and deficiencies, making construction designs both biddable and constructible. He tracks the design evolution in collaboration with architects, engineers, technical professionals, and subcontractors. Additionally, he monitors medium-to-large multidiscipline design-assist and design-build architectural-engineering agreements, focusing on deliverables and scopes of service.
