.CURRENT NOTED ITEMS
1. Parapet wall straps were not installed per detail Resolution: The contractor was informed and
1 /S4.10 the straps were being instal led while we were
on site.
2. One sheathing panel joint was warped. Resolution: The contractor was instructed to
install blocking at this location below the roof
deck.
3. The sheating was observed to be installed with Resolution: It was our understanding that the
all joints abutting tight rather than having a • building was to be roofed the following day
1/8" gap per the structural general notes. such that the roof sheathing would not be
exposed to prolonged wet weather.
4. `Shiners' were observed at the strap to blocking Resolution: The contractor was instructed to
connections at the Southwest corner of the roof. remove the nails and re -nail the strap into the
blocking.
5. All other nailing and strapping appeared t_ o be
in conformance with the project documents.
Any work observed and noted above shall not be considered a waiver of the duties and responsibilities of
other parties or of the requirement of strict compliance with the Contract Documents and the intent of the
project plans and specifications. This report shall not be considered to specifically address every detail or
location of the work in progress, but is rather a general observation of field conditions of the day of t he
report.
