MUELLER & ASSOCIATES CONSULTING, LLC (MA) performed an investigation, and water testing of the existing roof, façade, and windows. As a result of MA’s investigation, it was determined that the exterior facade and windows were deficient. In order to prevent large window expenditures MA devised and implemented a plan to better drain the existing window enclosures and prevent full replacements, potentially costing the client millions. MA testing was successful and modifications were implemented building-wide, removing infiltration issues for the client at well-under-expected costs. Services provided include a Façade Inspection, Construction document preparations in the form of drawings, specifications, and bid table. A Façad restoration of the north, east, and west elevations were performed, in addition to water testing of the window assemblies.
