The SWR Institute’s Trinity Project Awards Program honors industry projects that demonstrate excellence and innovation. FEA was presented the Trinity Award- 2013 for Recognition of Outstanding Collaborative Partnership between Members in the Waterproofing Category for the project – Three Parkway Facade Repairs.
This program showcases member companies and their unique project accomplishments. The program also provides an excellence benchmark for future projects to continuously improve and advance the sealant, waterproofing and restoration industry. The awards recognize project collaboration among the three types of SWR Institute members: Associates, Contractors and Manufacturers. The three-member judging panel includes an SWR Institute member from each group. Submissions are judged on criteria including problems, challenges and solutions; safety considerations; and environmental impact.

About the Project
The Three Parkway Façade project used 3D laser scanning technology to render models of elevation planes to detect brick movement and the need for retrofit masonry ties. The collaborative team process also helped address the project’s atypical brick support and flashing issue, which was a persistent source of water infiltration.
Technology
The project used three-dimensional laser scanning to gather data that allowed the project team members to determine where masonry wall ties should be installed. From the project submission: “The scanning was used to establish a uniform plane at each elevation. Once a base plane was established, limits could be placed on the point data to determine their location relative to the plane. “An analysis could show, for example, any point more that ½ -inch away from the base plane, These points gathered together would represent brick movement away from the building and a possible area where retrofit masonry wall ties should be installed.”
Problems and Solution
When it came time to install waterproofing at an atypical brick support location, the condition of the existing steel angles was unknown. The project team did not anticipate removing the corroded angels, but their condition necessitated it. The contractor developed a solution to improve the angles’ constructability. Temporary steel angles were placed upside down from their typical configuration to support a sloped brick condition above. From the submission: “ The temporary angles ere then supported by small steel clips slid onto the existing angle fasteners after support allowed large areas of the flashing condition to be addressed at once while permitting angle replacement as needed.”
