The building consists of several complex roof areas and varying wall systems. Two (2) mechanical mezzanine roofs were congested with ductwork and equipment for the pharmaceutical laboratories, resulting in ponding, obstructed drainage, and numerous roof penetrations. Vital Structures performed an evaluation of the existing EPDM roof system; including review of original design documents, infrared roof scan reports, destructive test cuts, peer review of the tenant mechanical upgrades, and programmatic leak testing of balconies, atrium skylight and rising walls.
- Mechanical duct supports mechanically fastened (screwed) through the roof membrane.
- Saturated roof assemblies with retained water under the roof membrane.
- Roof membrane punctures and slope-to-drain deficiencies due to saturating and crushing of the roof assembly.
- Masonry through-wall flashing deficiencies.
- Failed/dislodged gaskets at exterior metal panel walls.
- Skylight leaks corresponded with snowguard attachment areas, failed IGU butt-glazing joints, mullion joints/intersections, and skylight-to-rising wall connections (insulated metal panel and masonry walls).
- Balcony slope-to-drain deficiencies, poor waterproofing terminations, and improperly installed drain components.
