SGH investigated leakage, ice dams, and snow cornicing at the 10.6-acre, barrel-shaped high roof. We designed repairs, including the following:
Extending the existing built-in stainless steel gutter up to 18 ft wide and integrating the fully welded gutter and underlayment with the existing parapet, aluminum standing seam metal roofing, and building expansion joints to provide a watertight system
Modifying the existing roof drainage system to capture open channel flow in the built-in gutters and replacing existing dome roof drains with drop inlet drains integrated with the gutter and underlayment
Installing a mineral insulated heat trace system to promote positive drainage paths through ice and snow
We also investigated leakage into the building and failed expansion joints in the elevated roadway. SGH developed details for reconstructing roadway joints and designed related waterproofing repairs.
To improve environmental performance, SGH audited the BCEC’s energy, water, and material usage. We later conducted a detailed assessment to evaluate the feasibility of obtaining LEED certification. SGH led a team of consultants to demonstrate the facility’s sustainable performance and helped the BCEC achieve LEED O+M: Existing Building Silver certification.
