SolutionWJE engineers provided building enclosure review services from design through final construction. WJE reviewed the design details and made several detail modifications to better address possible water intrusion and air infiltration issues. WJE engineers recommended changes in flashing details and provisions for catching and diverting incidental water back to the exterior. Built-in gutters were designed, and WJE engineers discussed concerns about the proposed system. WJE engineers recommended the use of mockups and water testing to verify the efficacy and finished appearance of critical details.
By clarifying design details and recommending additional provisions not addressed in the initial design, WJE engineers improved the ability of the building enclosure to withstand the harsh Minnesota climate.
