FIELD REPORT
Michael Groome of RJK discussed the issues with PMA and CB before leaving the site.
Work Observed/Procedure
• Overall Progress
• Self-Adhered Air/Vapor Barrier Membrane Installation
• Installed Roofing - Area Designated as Part D
Observations
• Georgia-Pacific DensGlass sheathing is being installed to steel stud infill framing on the first floor areas of
the building designated as Part C and Part D. (Figures 1, 2)
• At Part D, south elevation, Gridlines D1-D5 GCP Perm-A-Barrier Aluminum Wall Membrane self-adhering
air and vapor barrier (AVB) was installed by Beacon Waterproofing and Restoration Inc (Beacon).
Primer/adhesive was applied to the DensGlass Sheathing prior to RJK’s arrival on site. The membrane was
installed in a water shedding fashion, with a minimum 2-inch side lap. Beacon rolled in the membrane
utilizing a silicone roller, per the manufacturer’s requirements. (Figures 3 - 6)
• PVC Roofing installation was completed prior to RJK’s site visit by Stanley Roofing Company (SRC).
Methods of installation could not be confirmed regarding the substrate board, vapor barrier, insulation and
fastening pattern, coverboard and membrane. Completed details appeared to be in accordance with the
manufacturer’s requirements and industry standards.
• PVC T-joint patches were installed at T-joints, per the manufacturer’s requirements. (Figure 8)
• PVC prefabricated pipe flashings were installed at roof penetrations with sealant set between the top of the
flashing and penetration with a steel clamping ring installed, creating a compression seal at the top of the
flashing, per the manufacturer’s requirements. (Figure 9)

• The PVC membrane extends past the clamping ring at drains and is set in Sikaflex-1A elastomeric joint
sealant and fastened under the clamping ring. The membrane is a minimum 1-inch from the clamping ring
and larger than the drainpipe, per industry standards. (Figures 10, 11)
• The PVC roof membrane is lapped over the top of the parapet and affixed to the exterior face of the parapet
wall, as required. (Figures 19, 20)
Discussions
Roofing Installation
1.1 Open Seam - Part D Roof Concrete Slab that Intersects Grid Lines D21, and B.5 - A loose lap was observed
at a patch installed over a fish mouth. Per discussion with Ryan DiRico, the area will be opened for
installation of the curbs and mechanical units and, therefore, it is likely the patch is temporary as the
membrane in the area will be reinstalled. If the patch is temporary, then no repair is necessary as it will be
removed. If the patch is permanent, the patch is to be heat welded and pressed/rolled in, to close the void, or
repaired per another manufacturer’s approved method. (Figures 12 - 14)
1.2 Uncovered Polyisocyanurate Insulation - Part C and Part D Roofs - Stored polyisocyanurate insulation has
been covered with tarpaulins secured utilizing ropes. The installed tarpaulins are damaged and leaving the
insulation exposed to the elements. Moisture sensitive materials are to be fully covered from the elements,
to prevent wet materials from being installed in the roofing system. All materials that are wet are not to be
installed in the roofing system, per the industry standards, project specifications and manufacturer’s
requirements. (Figures 15, 16)
1.3 Open Membrane at Penetration - Part D Roof, East Connection to Part C, Grid Lines C115 and D.1 - A metal
penetration in the parapet wall was not temporarily sealed, leaving an open path for moisture to enter the
newly installed system. Shortly after RJK’s departure from the site, the issue was resolved and photographs
were provided by Ryan DiRico. Sealant was applied to the area to create a temporary seal until the metal is
removed and the roof detailed per the manufacturer’s requirements. (Figures 17, 18) Item Resolved.
