Condition Assessment-Parking Garage
The Union Station, in Washington DC, is a national landmark and critical multiple modal transportation hub for our national capital. The parking structure in the bus depot area of the structure has been exposed to aggressive deicing chemicals deposited from bus traffic. The concrete has been experiencing spotty corrosion-related delaminations. Importance of this transportation hub for the city, requires expert assessment of the needed repairs.
Timothy Haahs Associates were contracted by the property management to design and oversee the restoration of the bus depot areas of the Union Station. TCG was subcontracted to provide corrosion survey, delamination survey, and contamination studies. TCG conducted the non-destructive testing and field survey in collaboration with THA. TCG also brought back the concrete specimens extracted in the field for laboratory testing. THA and TCG worked in concert to put forth the cost-effective restoration solution for the bus depot.
