List of Answers to the Questions- W91QVN-22-R-0162 REPAIR EXISTING LAYDOWN AREA TO MOVE

LAND FARM

No. Question Answer 1 According to the drawing C-7, It is necessary to install contraction joint for storage basin for oil water/oily sediment.

But we recognized there is no contraction joint on drawing C- 10 which is concrete with re-bar. Please let us know about the contraction joint

All joints are shown on C-7.

2 According to the drawing C-10, the size of Water Storage Basin Details is 15M X 12M. Do we have to install the safety facilities for the open area structure?

No change. No need to install

3 According to the drawing C-6, the length of Sewer Line (200MM DIA, PVC) is approx. 160LM, nothing else. and for drawing C- 4, whole length of the Sewer Line is 95 + 160 + 160M. Please check the length for the Sewer Line.

Total quantity of sewer line is 330m. Refer to C05, C06 drawings revised.

4 The distance between each manhole is 160M and the Slope is 0.5%. There might be drain issue with the long distance and little slope without the additional manhole.

No change, additional Manhole is not required.

5 Project Areas for the Force Main Manhole (Lift Station) and Sewer Line are overlayed existing company's project area. We also need the information for the existing facilities and Asphalt Pavement Area of Regional Correctional Facility for Force Main Line Project.

(After checking the spec, we have to review the process if we have to replace or reschedule the process before they install the asphalt pavement)

The government will coordinate between the two contractors to ensure the work for the sewer line is properly completed. This will include government coordination for scheduling of work.

6 According to C-3, It is written 'refer to C-12' for Construct Brick Pavement with Grass. But C-12 is the drawing for the Chainlink Fence and Gate. There is no Brick Pavement Details.

Changed brick pavement to AC pavement.

Refer to C02 drawing revised.

7 According to C-5, Utility Plan (1), The Slope is - 0.5% from the concrete center head wall(Elevation TOP 6.40) at the center to the left steel grating. It means EL for the steel grating should be 6.15(25cm down). Accordingly, The EL for the rest of the storage basin & Oil Water Separator & Sewer Manhole & Force Main Manhole should be changed. Please check the EL on the drawing.

No change.
