4. Sheet C-102 and C-103, Construction Flag Note 7: Instead of running the new force mains through the existing valve, re-route the new effluent piping around the valve box. 45 degree elbows must be used for 90 degree turns. Thrust blocks and/or thrust restraints must be used per the specifications.
5. Sheet C-102 and C-103, Construction Flag Note 14: It appears the new vertical force main pipes will be impacted by the location of the existing hatch cover. If so, 45 degree elbows must be installed to clear the hatches.

7. Sheet C-103, Construction Flag Note 20: The 2” water RPX and hose bibb are not required at this location.
8. Sheet C-103, FAC 90404, existing riser pipe from base elbow: The existing riser pipe is 8” pipe not 6”, so an 8” check valve assembly must be installed.
9. Sheet C-104, Construction Flag Notes 13 and 14: Restraints are required. Further guidance will be provided if necessary after construction award.
10. Question: Sheet C-104, Construction Flag Notes 10 and 11: The C900 pipe and fittings are required but have a long lead time so plan accordingly.
11. Sheet C-104, Construction Flag Note 9: A concrete wet well, not fiberglass, is required. Further guidance will be provided if necessary after construction award.
12. Sheet C-503, temporary jumper detail: Clarification on each wash water service connection will be addressed on an individual basis. The Contractor must submit an RFI if exception is taken to the temporary BFP jumper.
