Guthrie Library consists of the original building built in the early 1900’s and an addition completed in 2008. The new addition has experienced years of window and envelope leaks and failures from the roof down to the foundation walls. Major concerns were brought to our attention with the raised plaza deck and the membrane protection system installed within the concrete deck structure.
The Witmer team collected, logged, and documented existing conditions and materials and reviewed existing documents prior to the invasive procedure stage.
Invasive inspection areas were opened up by the team at many critical areas where water was entering the building along with areas where it was determined that the original construction documents were not previously followed. Other opened areas such as the existing flashings, damproofing, waterproofing membranes, anchorage and ties, and other critical components in existing construction locations were documented as to original condition and placement location and properly photographed. This information was vital in providing the Borough of Hanover and their legal team with needed information about past construction placement and workmanship practices.
Our team also created a budgeted repair cost, acted as technical advisor for selective materials and methods of installation, and performed as professional witness on behalf of the owner as needed.
This project is now in the final stage including the generation of project specifications, documents, and drawings for the bidding stage in selection of a new construction team to complete the project requirements.
