State Farm Mutual Automobile Insurance Company (State Farm) retained RRJ to perform investigative diagnostic water testing in an effort to replicate the numerous water leakage staining patterns at Building J at their campus. The investigation also included disassembling components of the strip window system, making exterior masonry inspection openings, and removing interior finishes, as necessary, to determine as-built conditions and pathways for water leakage. RRJ’s scope was later expanded to include investigation and repairs at the window and facade systems of additional buildings at their corporate campus.
Based on the investigation, RRJ revealed various contributing factors to the water leakage at the exterior enclosures, which included windows, brick masonry, and metal panels. Primarily, shrinkage of the thermal break at the window framing components coupled with glazing gasket shrinkage resulted in uncontrolled water leakage into multiple buildings on their campus.
Although the most comprehensive, effective, and long-term approach presented by RRJ included complete window replacement, RRJ also presented alternative corrective measures that would eliminate the leakage at a reduced cost and minimal impact on interior operations.
Alternative options were ultimately approved by State Farm, and RRJ later performed repair design, bidding assistance, and construction observation services following the water leakage investigation phase.
