Preconstruction, construction management and general contracting.

Pick the delivery method that fits your schedule, financing and design status. Every method comes with the same weekly reporting and the same paperwork.

Preconstruction

Joining during schematic design or design development, we test the design against the budget before it is locked.

  • Conceptual and DD-level estimates by CSI division
  • Constructability review of drawings
  • Value engineering options with cost and schedule effect
  • Long-lead procurement plan (switchgear, RTUs, storefront)
  • Master schedule and phasing plan

CM at Risk with GMP

We are selected on qualifications and fee, then carry the risk of a guaranteed maximum price built from competitive subcontractor bids.

  • Open-book bid leveling, three bidders per trade where available
  • GMP with named contingency and allowances
  • Buyout savings returned as reported
  • ConsensusDocs 500 or AIA agreements

Design-Build

One contract for design and construction, with a single point of responsibility to the owner. We hold the architect and engineers under our contract.

  • Program verification and test fit
  • Design team management through CDs
  • Progressive pricing at each design milestone
  • Permit submittal coordination

General contracting and tenant improvements

Hard-bid lump sum on completed documents under Design-Bid-Build, including occupied-building interior work.

  • Lump-sum proposal with clarifications and exclusions
  • After-hours and phased work in occupied buildings
  • Landlord work letter coordination
  • Punch list and turnover to tenant move-in
