Museum of Science Parking Garage
Scope/Solutions
The Museum of Science parking garage was built in two phases in the late 1960s and partially spans the Charles River. After thirty years of exposure to weather and vehicles, chlorides from deicing salts permeated the top surface of the concrete slabs. Working for the owner, SGH assessed the condition of the concrete garage and recommended a rehabilitation program to extend the useful life of the structure.
The five-level parking structure has an approximate gross area of 68,000 sq ft per level. The garage is a combination of precast, prestressed concrete elements and cast-in-place, post-tensioned concrete elements. Our services included the following:
- Determined the condition of the garage through a hands-on investigation
- Examined the condition of the concrete
- Evaluated the extent of chloride contamination from deicing salts typically brought into the garage by vehicles
- Identified and prioritized remedial work to repair deterioration, control leakage, and extend the useful life of the garage
- Estimated costs for the remedial work

Additional Projects
Northeast
Cornell University, Pedestrian Suspension Bridge
Cornell University sought to install cable net barrier systems on four university-owned bridges, including a pedestrian suspension bridge that spans over Fall Creek. SGH analyzed the existing suspension bridge structure and the effect of the cable net on the bridge.

Eastern Maine Medical Center Parking Garage
The Eastern Maine Medical Center expansion included a new parking garage to connect to the existing garage and the addition of snow-melt units to facilitate snow removal. SGH was the prime consultant, structural engineer of record, and the precast concrete specialty engineer for the project.
