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

First Street Bridge
The First Street Bridge is a bascule drawbridge carrying traffic westbound over Broad Canal. The bridge suffered from several forms of deterioration including damage to the concrete counterweight. SGH prepared remedial designs and developed construction documents for rehabilitation of the bridge.
