Answer 3: No information is available.
Question 4: The photo on Figure #4 of the Bradley Pump Station indicates the new underground force main will pass under an existing paved sidewalk and an existing chain link fence. Is the contractor responsible for costs to restore the paved sidewalk and fence back to the existing condition?
Answer 4: Yes
Question 5: The photo on Figure #2 of the Bradley Pump Station indicates the existing flow meter is to be demolished. Is the contractor responsible for disconnecting the existing electrical and signal wiring from the existing flow meter?
Answer 5: Yes
Question 6: Figure #5 of the Bradley Pump Station indicates the new flow meter is to be installed on the pipeline. We have the following questions on the flow meter:
Question 6a: Is the contractor responsible for providing the conduit and wiring for the new flowmeter?
Answer 6a: No.

To remove the existing force main pipe the existing 5’ x 3’ concrete entrance landing will have to be demolished. Will we have to replace the concrete entrance landing? If we do have to replace the pad can a detail be provided on the replacement pad?
