Balfour Beatty engaged WJE to attend selected planning and progress meetings, to develop a water leakage testing protocol, to perform water leakage testing, and to assist with design of repairs or design modifications to alleviate problematic conditions. Various interfaces between fenestrations, cladding, roofing, and waterproofing components required design input from WJE to resolve conflicts during construction.

WJE performed approximately 150 individual water tests, employing ASTM and AAMA testing procedures. WJE also witnessed fifty tests performed by independent testing agencies. Where leakage was observed, WJE provided guidance on the proper remedial measures to address the leakage. Follow-up testing was also performed at affected areas to verify the adequacy of remedial measures.

Many of the water tests performed by WJE required difficult access and creative methods of reaching the test location and performing the required testing. These tests were accomplished with the cooperative efforts of WJE and an in-house safety coordinator as well as with assistance from the involved subcontractors and general contractor. A good working relationship and communication were critical to ensure safe and successful testing at these locations.
