The inspection report summarizes the fireproofing work done at 152 West 124th Street in Manhattan. Three inspections were conducted to ensure the rear apartments on all 5 floors were completely fireproofed with 1 hour rated demising walls. Upon the initial inspection, gypsum board was installed over 80% of wall joints but caulking was missing. Subsequent inspections found the work nearly complete except for minor areas that were then finished. The final inspection on October 7th confirmed the fireproofing was now 100% complete and certified the apartments met the 1 hour fire rating requirement.

1. INSPECTION REPORT – 152 WEST 124TH
STREET - Manhattan
Date October 10, 2009
___________________________________________________________________________
On Wednesday, October 7, 2009, I inspected the building at 152 West 124
th
Street in Manhattan.
Reason for inspection: To ensure all rear apartments on all 5 floors are completely fireproofed at
demising walls to create 1 hr. rated partitioning from floor to floor.
Method of fireproofing. A double layer of sheetrock on 3-5/8” metal studs filled in with mineral
Wool was installed from floor to floor. At joists above ceiling, a layer of gypsum board was installed
below and between joists to create a gap free meeting joint, flush to the sub-floor above. The
meeting joints were then caulked continuously with fire-proof Hilti caulking along the gypsum
board edges, joist perimeter and subfloor surface.
I paid several visits to the site to inspect that all joints were continuously caulked, leaving
no gaps, thus creating 1hr fire rated demising walls between apartments.
Note:
1. upon my first visiting inspection, approx August 1, 2009 - Gypsum board was installed over
80 percent of the wall to floor meeting joints, but there was no caulking installed. I instructed
the contractor to install the balance of the gypsum board layers. Also, at the bathrooms on all
floors, the demising walls were not complete. I instructed the contractor to complete the
demising walls, so the final layer of gypsum. board and caulking could be installed.
2. Upon my second inspection on September 24, 2009. All gypsum board was installed and
80 percent of caulking. Caulking was not installed in areas where the contractor could not
access above the ceiling. I therefore instructed the contractor to cut away the gypsum board
ceiling along the entire perimeter wall, so he could access the locations not caulked, then to
caulk the entire perimeter of the ceiling.
3. Upon my third visit on October 7, 2009 99 percent of caulking was complete. The contractor
had cut - away the ceiling to complete the caulking and approx. 4 ft. of gypsum board was
installed to complete the bathroom demising walls and caulked. There were minor sporadic
locations not caulked, which were caulked during my inspection, for an entirety of approx. 4 ft.
for all 5 floors combined. I recognized that 98 percent of the fire-proofing was completed,
therefore, I instructed the contractor to touch up these areas, to complete the job. This was
performed and also inspected by the HPD inspector.
I now certify that the entire rear apartments are 100 percent 1hr fire rated at
the demising walls.
