92. General note #7 on all demo sheets AD101A-101D state that all painted surfaces are assumed to be lead paint. However, the Hazardous Materials Report provided in the specs states in the Findings section that of all 98 samples collected from various areas around the building, only 1 sample on one door contained lead. To treat all painted surfaces as lead will greatly increase the demolition costs. With this information in mind, should the contractors still treat all painted surfaces as lead contaminated paint?

A-E Response: Use the Hazardous materials report.

93. General note #7 on all demo sheets AD101A-101D state that all painted surfaces are assumed to be lead paint. Does this apply to the existing floor coatings as well?

A-E Response: See response to #92

94. If all painted surfaces are to be assumed as lead contaminated, should all painted surfaces that are to remain such as CMU an precast concrete walls, doors and frames, exposed ceilings, etc, get fully abated or can it be left in place and encapsulated?

A-E Response: New steel does not need to be fireproofed unless surrounding framing is fireproofed

98. Notes 14, 15, 16 on PD110B appear to call for all under slab plumbing associated with removal of certain plumbing fixtures back to the mains. Is the intent here to sawcut and demo existing concrete, remove the under slab piping and patch back the concrete?

A-E Response: The modified space for the area where note 14 is present is an office, and there is no need for a floor drain. There are incomplete existing sanitary drawings for this space, so the intent is to sawcut and demo the existing floor drain below slab and cap it. For notes 15 and 16, those fixtures are being completely removed, so demo and cap as shown on the plumbing plan.

99. If the intent of Notes 14, 15, 16 on PD110B is to remove and patch concrete, please identify the slab thickness.

A-E Response: See response to Question #27

100. Detail E4&A1/P-501 shows new emergency eye wash fixtures. The details are used on the new plumbing drawings P-110A-110D. These fixtures have underground sanitary drains. Will new underground sanitary lines be required under slab, or do they use existing drains?

A-E Response: Per UFC and International Plumbing code, drain are not required for emergency fixtures. Where floor drains are not shown on plan, floor drains will not be provided.

101. Sheet P-110A calls out 2” dia. sanitary lines. Are these new sanitary lines which need to be installed under the existing concrete slab, or are they existing?

A-E Response: These 2” diameter sanitary lines are connected from a pump and routed above the ceiling per note 6. The 2” line is to be routed to the nearest plumbing stack in the ceiling through the addition of a hub drain. Please refer to the updated Drawing P-110B in a forthcoming Amendment.

102. Note #5 on sheet P110A says to cleanout sanitary piping from this space to confirm no clogs. Cap all sanitary in this space. Is this under slab existing sanitary?

A-E Response: Correct. This is an existing line, and there is a floor drain in that space. The existing floor drain has no use in the modified building. As it currently exists, staff made it known that the line has a clog and tends to provide a foul odor in that space. The existing record drawings for sanitary were incomplete, so the routing beyond the floor drain is unknown.

103. Note #6 sheet P110A says to connect 2” sanitary to discharge line from DP-1. Is this sanitary under slab and requires concrete removal and patching?

A-E Response: These 2” diameter sanitary lines are connected from a pump and routed above the ceiling per note 8. The 2” line is to be routed to the nearest plumbing stack in the ceiling through the addition of a hub drain. Please refer to the updated Drawing P-110B in a forthcoming Amendment.

104. Just so we can clearly answer the question, is there any new or existing plumbing that requires the existing concrete slab to be removed and patched back? Please identify these locations.
