19. Drawing G-001
Correct “EDS-1, BSL3” in Index of Drawings to “EDS-2,
BSL3” for Dwg No. S-112, M-112 and E-403.
- Update Callouts “01” and “02” to match with Demolition
Notes where 01 for ABSL-3 EDS and 02 for BSL-3 EDS.
- Correct “BLS3” in Demolition Notes 02 to “BSL-3”
- General Notes No. 1 “DEMOLITION OF
WASTEWATER AND EFFLUENT
DECONTAMINATION SYSTEM OF BSL-3 MIGHT
REQUIRE TEMPORARY REMOVAL OF PARKING
LOT SHADES AND STEEL ROOFING.” Please confirm
removal or not removal “might” not recommended.
Update Callouts “01” and “02” to match with Key Notes
where 01 for ABSL-3 EDS and 02 for BSL-3 EDS.
Indicate type of slab that missing between beams B3 and
B4.
20. Drawing CD-110
21. Drawing S-110
22. Drawing S-111
All material shall be noncombustible material and not
generate any toxic gas
Branch Cable & Wiring - Electrical design shall be copper
conductors with 90 degrees (C) temperature rating
insulation and at all size cable per local code EIT.
LED Lighting Fixtures 100-277 Volt, please verify the
voltage. Is it 100-230 volt?
Light Switch Control at 120 up to 230 Volts AC. please
verify the voltage. Is it 100-230 volt?
Electrical Power System Requirements – Please verity; is
it 400/230 volts, 3 phase, 4 wire?
Recommend to have Gas Leak Detector install at both
above ground and underground.
Update “WWTP” in the title block to “WWTS”

Indicate type of slab that missing between beams B2 and
B3.
The size of the slabs and beams appears smaller than
expected for an underground structure. Please provide
calculations in the next design stage to confirm the design
complies with relevant codes and standards. The
calculations should include considerations for strength,
serviceability, stability, and durability. Additionally,
confirm if crack width control has been addressed in the
design.
The system does not show how to access underground to
check space around the tank nor access hatch.
- Please verity Key Notes: HEX 01 (duplicated) and HEX
15. Is steam generator required for the system?
- BSL-3 EDS-2 SCHEMATIC DIAGRAM: 9, effluent
from EDS BSL3 should be 10 on schematic diagram.
- The proposed WWTS is too close to the existing
electrical duct bank. Why does not it expand to other
direction (to Pump House) instead?
- How do you drive conduits, wirings, sizes without
providing load calculation or information to support the
design.
Excessive HEX 5 by the ABSL-3 EDS layout.
- Is the existing tank in Chemical Treatment Facility
duplicate to the underground chlorine tank (HEX 5)?
- Update drawing title in the title block to “Plumbing
Demolition Lay-Out”
- There are two drawings of PD-100. Please check.
Drawing on the last page (page 23) shall be drawing no. P110 as per the index of drawings.
- Update drawing tile in the tile block and on lay-out to
match with the information on the drawing.
04 (Thermal Effluent Decontamination system) is not
shown. It would appear to be intended to be the loop
diagram, but this is labeled 01 (cooling tower). Please
specify where in the diagram the EDS will be.
Pumping of contaminated waste should be avoided. If
necessary, please ensure proper pumps are used to
minimize potential for leak. Leak detection must be used.
Confirm that the top slab of the WWTS is designed to
withstand live loads, including the potential weight of a
fire truck and other heavy vehicles accessing the area.
