HealthcareGeneral contractor estimate

Harbor View Medical Office Building

A three-story medical office building with imaging, outpatient surgery suites and physician offices, estimated from 90% construction documents for a general contractor pursuing a competitive hard bid. LEEDS delivered a full Division 02 through 28 estimate with leveled subcontractor quotes and healthcare-specific alternates in six business days.

Scope estimated

What we measured and priced

1,960 CY structural concrete in spread footings, slab-on-grade and composite deck slabs with 142 tons of rebar
312 tons of structural steel framing with 32,000 SF of composite metal deck
16,000 SF of TPO roofing over tapered polyiso with insulated metal panel and brick veneer across 3 stories
118,000 SF of drywall partitions including lead-lined walls at 4 imaging rooms
Medical gas piping with 62 outlets, zone valve boxes and a manifold room
14 air handling units totaling 118 tons with HEPA filtration at 2 procedure rooms
2,000 A service with a 350 kW standby generator and 1,460 light fixtures
2 hydraulic elevators and 1.8 acres of parking, utilities and a stormwater vault

The estimating challenge

The 90% set carried a healthcare equipment schedule that was still moving, with four imaging rooms whose shielding, structural pads and dedicated electrical feeds depended on vendor data the owner had not finalized. Medical gas, nurse call and HEPA-filtered procedure rooms pushed the MEP share of the budget above 40%, so small quantity errors there would swing the bid. The contractor also needed the estimate split by floor to match the owner's phased occupancy plan, and had only six working days before bid day.

The result

LEEDS built the estimate by floor and by CSI division, carried the imaging rooms as a priced allowance with a documented basis for each shield thickness and pad size, and leveled eleven mechanical and electrical subcontractor quotes against our own takeoff. The contractor submitted at $18.6M and was awarded the project as low bidder, roughly 2.1% under the second bid. Final buyout landed within 1.8% of our estimate, and the imaging allowance covered the vendor's final equipment specifications without a change order.
