8. MAINTENANCE OF FLOW IN EXISTING SEWERS:

THE CONTRACTOR IS RESPONSIBLE FOR HANDLING AND ACCOMMODATING ALL EXISTING WASTEWATER FLOWS DURING THE WORK. THE CONTRACTOR WILL BE REQUIRED TO SUBMIT, FOR APPROVAL BY THE ENGINEER/TOWN, A DETAILED PLAN OF THE METHOD THE CONTRACTOR PROPOSES TO MAINTAIN THE EXISTING FLOW DURING CONSTRUCTION. THE PLAN MUST INCLUDE A PROVISION FOR HANDLING THE EXISTING PEAK FLOW BY PUMPING. WHEN PUMPING IS USED, AN IDENTICAL

STANDBY PUMP(S) SHALL BE ON SITE IN THE EVENT OF FAILURE OF THE PRIMARY PUMP(S).

IF, AT ANY TIME DURING CONSTRUCTION, EFFLUENT FROM THE EXISTING SEWER IS NOT FULLY CONTAINED BY THE BYPASS SYSTEM, GRAVITY SERVICE WILL BE RESTORED AND WORK SHALL BE SUSPENDED UNTIL THE PROBLEM IS RESOLVED TO THE SATISFACTION OF THE ENGINEER/TOWN. THIS INCLUDES WASTEWATER FLOWING INTO TRENCHES DURING EXCAVATION WORK. SEWER SYSTEM OVERFLOWS WILL NOT BE TOLERATED. ALL FINES IMPOSED ON THE TOWN AND ASSOCIATED

WITH OVERFLOWS CAUSED BY THE CONTRACTOR'S WORK SHALL BE PAID BY THE CONTRACTOR.

MANHOLES EMPLOYED AS SUCTION MANHOLES OR DISCHARGE MANHOLES FOR TEMPORARY BYPASS PUMPING OPERATIONS SHALL BE TEMPORARILY RAISED TO A MINIMUM OF TWO FEET ABOVE THE EFFECTIVE 100-YEAR FLOOD ELEVATION USING MANHOLE RISER SECTIONS. JOINTS BETWEEN THE EXISTING MANHOLE AND THE TEMPORARY RISER SECTION SHALL BE ADEQUATELY SEALED TO PREVENT WATER FROM ENTERING OR EXITING THE MANHOLE. IF THIS IS NOT FEASIBLE FOR A GIVEN LOCATION, THE CONTRACTOR MAY PROPOSE ALTERNATE MEANS OF PROTECTING THE SUCTION AND DISCHARGE MANHOLES FROM INUNDATION DURING SEVERE

WEATHER CONDITIONS, SUBJECT TO APPROVAL BY THE ENGINEER.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR NOTIFYING THE ENGINEER PRIOR TO ANY CHANGE IN BYPASS OPERATIONAL STATUS, INCLUDING INITIATING BYPASS OPERATION, RETURNING FLOW TO NORMAL GRAVITY OPERATIONS, ETC. REFER TO THE SPECIFICATIONS FOR MORE DETAILED INFORMATION REGARDING BYPASSING REQUIREMENTS. IN ADDITION, THE CONTRACTOR SHALL NOTIFY THE ENGINEER/TOWN PRIOR TO INSTALLATION OR REMOVAL OF PLUGS IN ANY SEWER LINE

(INTERCEPTORS OR CONNECTOR SEWER LINES).

IN THE EVENT OF AN ANTICIPATED EXTREME WEATHER CONDITION (E.G. HURRICANE OR OTHER LARGE PRECIPITATION GENERATING EVENT), THE TOWN MAY REQUIRE THAT THE BYPASS PUMPING SYSTEM IS TEMPORARILY DISABLED AND GRAVITY FLOW REESTABLISHED. IN THAT EVENT, ANY MANHOLES THAT ARE USED BY THE CONTRACTOR AS SUCTION OR DISCHARGE LOCATIONS SHALL BE REINSTATED TO THEIR ORIGINAL CONDITION OR BETTER TO PREVENT STORMWATER INTRUSION.

THE COST TO TEMPORARILY RESTORE GRAVITY FLOW AND TO SUBSEQUENTLY REINSTATE BYPASS PUMPING OPERATIONS SHALL BE INCIDENTAL TO THE COST FOR

BYPASS PUMPING.

9. TRAFFIC CONTROL:

THE CONTRACTOR SHALL SUBMIT TO THE ENGINEER/TOWN A DETAILED TRAFFIC CONTROL PLAN FOR PERFORMING ALL WORK IN ROADS AS REQUIRED BY THE TOWN.

THE TRAFFIC CONTROL PLAN SHALL BE SPECIFIC TO EACH ROAD AND EACH SEWER AND MANHOLE. THE TRAFFIC CONTROL PLAN SHALL BE MODIFIED AS NECESSARY IN THE FIELD TO ACCOMMODATE UNFORESEEN TRAFFIC CONTROL ISSUES AND PROBLEMS AND SAFETY CONCERNS. NO WORK SHALL BEGIN UNTIL THE TRAFFIC CONTROL PLAN IS REVIEWED AND APPROVED BY THE ENGINEER AND THE TOWN. WARNING SIGNS, BARRICADES AND FLAGMEN MUST BE PROVIDED IN ACCORDANCE WITH THE FEDERAL HIGHWAY ADMINISTRATION'S "MANUAL ON UNIFORM TRAFFIC CONTROL DEVICES" (MUTCD) AND VDOT STANDARDS. ACCESS SHALL BE MAINTAINED TO HOMES, RESIDENCES, AND BUSINESSES IN THE AREA AT ALL TIMES.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR PERFORMING VIDEO INSPECTIONS AND TAKING PHOTOGRAPHS OF THE ENTIRE PROJECT AREA, INCLUDING ALL AREAS TO BE USED FOR TEMPORARY ACCESS, PRIOR TO PERFORMING ANY WORK AS THE CONTRACTOR DEEMS NECESSARY. THE INSPECTIONS SHALL BE NARRATED TO DOCUMENT LOCATIONS AND DATES OF THE VIDEO INSPECTIONS. THE PHOTOGRAPHS SHALL BE DATE STAMPED.

THE PURPOSE OF THE INSPECTIONS AND PHOTOGRAPHS SHALL BE TO DOCUMENT THE PRE-CONSTRUCTION CONDITIONS FOR COMPARISON WITH THE FINAL RESTORATION WORK AND WITH ANY IMPACTS TO PROPERTY/ROADS THAT OCCUR DURING THE CONSTRUCTION. IF THE CONTRACTOR FAILS TO PERFORM THOROUGH AND COMPLETE INSPECTIONS AND PHOTOGRAPHS, AND THE TOWN OR ENGINEER RECEIVES COMPLAINTS ON THE FINAL RESTORATION OR IMPACTS TO ROADS OR PROPERTY, THE CONTRACTOR SHALL BE RESPONSIBLE FOR ANY AND ALL ADDITIONAL RESTORATION AND REPAIRS AS NECESSARY TO COMPLETELY

RESOLVE THE COMPLAINT/ISSUE AT NO ADDITIONAL COST TO THE TOWN.

NO WORK MAY BEGIN AND NO EQUIPMENT SHALL BE MOBILIZED TO THE JOB SITE PRIOR TO SUBMISSION OF THE VIDEO/PHOTO DOCUMENTATION AND REVIEW AND ACCEPTANCE BY THE ENGINEER. THE VIDEO/PHOTO DOCUMENTATION SHALL COVER ALL AREAS POTENTIALLY IMPACTED BY THE CONTRACTOR'S VEHICLES AND

EQUIPMENT.

11. CLEANUP WORK:

THE CONTRACTOR SHALL COMPLETELY CLEAN UP THE WORK SITE AT THE END OF EACH DAY.
