Response: Sanitary sewer.

Question 16

Posted: 3/27/2023

Question: The plan B001.1 calls for a temporary work bridge and also for a list of constraints in order to build it. Can you reconsider the option of Fluming the stream and temporary backfill to build access to the Abutment A Area, and restore it while moving to the Abutment B Area, if it is not in conflict with the existing 24" DIP?

Response: No.

Response: No.

Question 20

Posted: 3/29/2023

Question 22

Posted: 3/29/2023

Question: Drawing C031.1 shows permissible location for temporary bridge. But it is overlap with new bridge location. we are not be able to excavate new bridge abutments while temporary bridge is in this location. can you expand the LOD and allow us to install temporary bridge in upstream or downstream location. It will enable us to use the temporary bridge until we finish our work.

Question 30

Posted: 3/30/2023

Question: Looks like temporary path is within the LOD limit. Tree protection fences are running across the temporary path. If you need any construction fence around the LOD, it will go around the temporary path too, Then there is no access to the temporary path. Are you going to revise these drawings?

Response: No, drawings will not be revised. However, the construction fence will be installed to not interfere with the temporary paths.

Question 32

Posted: 4/4/2023

Question: Drawing sheet C091.1 shows 4 trees has to be removed. But sheet C021.1 shows 5 trees has to be removed. What is the correct number of trees has to be removed?
