7. Upon completion of all sewer construction, testing and repair, the Contractor shall conduct a color TV acceptance inspection of all mainlines in accordance with OSSC (ODOT/APWA) 445.74 to determine compliance with grade requirements of OSSC (ODOT/APWA) 445.40.b (no deviation greater than 1/32-inch per inch of pipe diameter [1/2-inch max for pipes>16-inch diameter], & no reverse sloping pipe inverts) and to verify pipelines adequately cleaned. The TV inspection shall be conducted by an approved technical service, using a track or wheel propelled self-leveling auto-focus pan-head camera which is equipped to make audio-visual recordings of the TV inspections.

Unless otherwise required by the agency with jurisdiction, a standard 1-inch diameter ball shall be suspended in front of the camera during the inspection to determine the depth of any standing water. Sufficient water to reveal low areas or reverse grades shall be discharged into the pipe immediately prior to initiation of the TV inspection. A digital recording and written report shall be delivered to the JHA Engineer.

8. Prior to or concurrent with connection to a sanitary sewer lateral, it shall be demonstrated to the JHA that the lateral is not obstructed. This shall be accomplished by “snaking” the service lateral downstream of the connection point to the mainline, or similar method acceptable to the JHA. JHA personnel or authorized agent shall be present during the “snaking” or other demonstration method.

9. Sewer service from upstream and affected properties shall be maintained during construction unless prior written JHA approval is granted. Bypass pumping or other methods used to maintain sewer flows shall be the Contractor's design, subject to approval by the JHA. The bypass system shall be capable of conveying flows when the sewers are flowing full. Normal unrestricted flows shall be restored at the end of each work day. Bypass systems left in place or operated outside normal working hours shall be monitored continuously by the Contractor personnel unless alternate arrangements proposed by the Contractor are acceptable to the JHA (ie. high level & pump fail alarm callouts, etc.).

The Contractor shall provide for JHA review all submittal information required to demonstrate (to the satisfaction of the JHA) compliance with these requirements. Contractor shall be responsible for all costs related to cleanup, damages and fines resulting from any sewerage spill or overflow associated with any methods used to convey sewage flows during construction.

10. Thrust restraint shall be provided on all pressure pipelines meeting the same standards and requirements as for water mainlines.

GENERAL STREET LIGHTS:

1. If required, street lights shall be installed after all other earthwork and public utility installations are completed and after rough grading of the property is accomplished to prevent damage to the poles.

2. Public street light poles, conduit and junction boxes shall conform with the requirements of the JHA and the power company providing service. Junction boxes exposed to traffic loads shall be H-20 rated and set to finish grade. Direct bury street lights poles shall be set to a depth as specified by the manufacturer, but not less than 5 feet.

3. Street light poles shall be installed within one degree (1) of plumb.

4. Street lights shall be directed and hooded so they shine only on the parking lot for this site only.

5. All public street lights shall be energized and fully operational prior to requesting final inspection by the JHA.

PIPED UTILITIES:

1. Contractor shall coordinate and pay all costs associated with connecting to existing water, sanitary sewer and storm sewer facilities.

2. Unless otherwise noted, materials and workmanship for water, sanitary sewer and storm sewer shall conform to 2024

OSSC (ODOT).

3. The contractor shall have appropriate equipment on site to produce a firm, smooth, undisturbed subgrade at the trench bottom, true to grade. The bottom of the trench excavation shall be smooth, free of loose materials or tooth grooves for the entire width of the trench prior to placing the granular bedding material.

4. Unless noted elsewhere, all pipe shall be bedded with minimum 6-inches of ¾” minus granular crushed rock bedding and backfilled with compacted ¾” minus crushed rock in the pipe zone (granular backfill shall extend a minimum of 12-inches over the top of the pipe in all cases). Granular trench backfill shall be used under all improved areas, including sidewalks. Granular trench backfill shall be compacted to 92% of the maximum dry density per AASHTO T-180 test method (modified Proctor).

5. Unless noted elsewhere, granular backfill shall be ¾”-0 conforming to 2024 OSSC (ODOT) 02630.10 (Dense Graded Base Aggregate), with no more than 10% passing the #40 sieve and no more than 5% passing the #200 sieve.

6. If trenches are over-excavated for any reason, over-excavation shall be filled to the design trench subgrade (ie. to the bottom of the 6” thick pipe bedding layer) with compacted, well-graded granular backfill as specified (the use of open graded rock for trench foundation stabilization is prohibited unless it is completely encapsulated in geotextile fabric & approved in writing by the Engineer).

7. Temporary thrust restraint on pressure pipelines shall be provided at all locations where necessary due to construction sequencing shown on the drawings, required by JHA standards or chosen by the Contractor. The adequacy of the temporary thrust restraint shall be the Contractor's sole responsibility, but shall be acceptable to the JHA and any other agency with jurisdiction. Any movement of the pipe or fittings during pressurization of the pipeline or connection shall be considered evidence that the temporary thrust restraint is not adequate, and the pipeline or connection shall be depressurized and the thrust restraint increased as necessary. Re-pressure testing or re-chlorination, if deemed necessary at the sole discretion of the JHA, shall be completed at the Contractor's expense.

8. Contractor shall arrange for and pay all costs to abandon existing sewer and water services not scheduled to remain in service.

9. All piped utilities abandoned in place shall have all openings closed with concrete plugs with a minimum length equal to 2 times the diameter of the abandoned pipe.

10. The end of all utility stubs shall be marked with a painted 2 x 4, extending 2 feet minimum above finish grade (painted white for sanitary sewer, green for storm), and wired to pipe stub. Tracer wire shall be extended (and attached) to the top of the 2 x 4 post. Type of utility (ie. sewer, storm, etc.) and depth below grade to pipe invert shall be clearly & permanently labeled on the marker post.

11. Contractor shall provide all materials, equipment and facilities required for testing all utility piping in accordance with JHA construction specifications.

12. Unless noted elsewhere, all water, sanitary and storm sewer piping shall have an electrically conductive insulated 12 gauge solid core copper tracer wire the full length of the installed pipe using blue wire for water and green for storm and sanitary piping. Tracer wire shall be taped to the top of the pipe at 10 foot maximum intervals and shall be extended up into all valve boxes, manholes and catch basins and accessible from the surface. All tracer wire splices shall be made with corrosion resistant waterproof wire nuts ( select from the ODOT QPL consistent with the intended use). Tracer wire penetrations into manholes shall be within 18 inches of the rim elevation and adjacent to manhole steps. The tracer wire shall be tied to the top manhole step or otherwise supported to allow retrieval from the outside of the manhole or catch basin.

13. No trenches in roads or driveways shall be left in an open condition overnight. All such trenches shall be closed before the end of each work day and normal traffic flows restored.

14. Before mandrel testing, TV inspection or final acceptance of gravity sewer or storm pipelines, all trench compaction shall be completed and all sewers and storm drains flushed & cleaned to remove all mud, debris & foreign material from the pipelines, manholes and/or catch basins.

15. Where future extensions are shown upstream of new manholes (sewer or storm), catch basins or junction boxes, pipe stubs (with gasketed caps) shall be installed at design grades to point 2' minimum outside of the structure.

16. Unless authorized in writing by the JHA prior to the start of the work: trenching within existing paved streets shall be backfilled and repaved with asphalt pavement; trenches within each block or intersection shall be permanently repaved within 21 days of the start of excavation (including completion of all inspections, testing & corrective work required by JHA standards prior to paving). These time frames apply independently and separately to each block or intersection where trenching work occurs.

SEWER AND STORM WARRANTY INSPECTIONS:

1. Re-inspection of the sanitary sewer and storm drainage systems by cleaning & TV inspection shall be performed during the last month of the warranty period, as well as visual inspection of all sanitary sewer manholes during the wet weather season (any visible groundwater infiltration or leakage constitutes a failed manhole test, and will require warranty correction). Based on the results of the TV inspections and/or the JHA's warranty inspections, additional warranty test may include mandrel testing or low pressure air testing. The results of these test(s) will be used by Public Works to determine final acceptance. The cost of these re-inspections and any corrective work that is required prior to final acceptance of the system is warranted and corrective work shall be responsibility of the Contractor. The warranty period will not be considered to be complete, and maintenance bonds will not be released until after all warranty inspections are finished and any resulting corrective work is completed.

GENERAL MANHOLE NOTES:

The following notes shall apply unless noted elsewhere in the drawing: (in case of conflict the plans shall supersede)

1. All precast manholes shall be provided with integral rubber boots. Lockdown lids shall be used on manholes outside of public right-of-way only where specifically required by Public Works.

2. All connections to existing manholes shall be made by core-drilling the existing manhole structure and installing a rubber boot. Connections to manholes shall be watertight and shall provide a smooth flow into and through the manhole. Small chipping hammers or similar light tools which will not damage or crack the manhole base may be used to shape channels. Use of large pneumatic jackhammers shall be prohibited.

3. All interior joints, penetrations & any exposed lifting holes shall be grouted following manhole assembly. The grouting and channels of all manholes shall be smooth and uniform, and shall not retain water or debris. Any grout or concrete splatters (in channels, on channel benches, on walls or on steps) shall be removed by the Contractor.

4. Unless otherwise approved in writing by the Public Works Director and the JHA Engineer, manhole steps shall be installed in any manhole which does not have existing steps, and which is connected to or otherwise altered in any way.

5. Manhole channel depths (sewer & storm) shall be to the heights shown on the drawings, but in no case shall the channel depth be less than 2/3 of the pipe diameter. Flow channels in manholes shall be of such shape (semi-circular bottoms) and slope to provide smooth transition between inlet and outlet sewer size/ invert to minimize turbulence and to ensure that the manhole channels are self-cleaning. Channels, as well as shelves between the channels and the manhole walls, shall be sloped to drain per plan details.

6. For all sanitary sewer manholes, external mastic wrap joint seal (9-inch minimum width) shall be installed on all manhole barrel joints & pickholes after assembly, prior to backfilling (materials shall selected from the ODOT QPL consistent with the intended use). The exterior of the manhole barrels adjacent to each joint shall be clean (under the mastic wrap) to ensure a good seal (use wire brush to clean the exterior surface under the mastic wrap to remove all dirt, loose particles or deleterious material). The mastic wrap shall be held in place with plastic stretch wrap (ie. pallet wrap plastic, 3 layers minimum) during backfilling. Plastic wrap shall be installed immediately after the mastic wrap is placed.

7. Contractor shall be responsible to verify manhole finish rim elevations match with finish grade or are set above finish grade as required to conform with JHA standard details. Manhole rim elevations shall be adjusted as required to conform with this requirement.

8. All sanitary sewer manholes in low areas which are subject to flooding or water ponding (including all lawn, landscape or gravel areas, or low areas of parking lots, or manholes closer than 4 feet clear of parking lot curblines or existing/future street curbs, adjacent to ditched, etc.) shall be provided with inflow protector lid inserts (whether or not such MH inserts are specifically noted on each applicable drawing sheet). Manhole inflow inserts shall be of ABS or HDPE plastic, and shall include integral lifting lugs on each side of the insert allowing removal with a manhole hook (lift straps are not an acceptable alternate), a factory installed closed cell neoprene rubber gasket bonded to the underside of the insert rim. Unless waived in writing by Public Works (case by case basis), a clog-free vent-valve (materials shall be selected from the ODOT QPL consistent with the intended use) shall be provided on each unit. Inserts shall be ManPan manhole inserts or approved equal.

9. All sanitary sewer manholes shall be vacuum tested following completion of paving or final surface restoration. All testing shall conform with the JHA and 2024 OSSC (ODOT).

10. Existing sanitary sewer manholes to which new pipes are connected (or where existing pipe connections are modified) shall be sealed as required and pass a vacuum test prior to final approval.

11. Unless otherwise approved in writing by the Public Works Director, Public Works staff shall be present for all manhole testing. Visible groundwater infiltration or leakage constitutes a failed manhole test, whether or not the vacuum test is successful.

12. Existing manholes where pavement or surfacing is replaced around the manhole shall be sealed as required and pass a vacuum test following completion of paving or final surface restoration.

13. All manholes shall be thoroughly cleaned prior to being placed in service and/or accepted by the JHA, including removal of any debris, excess grout in manhole channels or on manhole steps, etc.

GENERAL STORM DRAINAGE NOTES:

The following notes shall apply unless noted elsewhere in the drawing: (in case of conflict the plans shall supersede)

1. Storm drain pipe materials shall conform to the construction drawings and JHA requirements. Contractor shall use uniform pipe material on each pipe run between structures unless otherwise directed or approved. Jointed HDPE pipe shall not be used for slopes exceeding ten percent (10%).

2. Catch basins and junction boxes shall be set square with buildings or with the edge of the parking lot or street wherein they lie. Storm drain inlet structures and paving shall be adjusted so water flows into the structure without ponding water.

3. Unless otherwise approved by the Engineer, all storm drain connections shall be by manufactured tee or wye fittings.

4. Sweep (deflect) storm drain pipe into catch basins and manholes as required. Maximum joint deflection shall not exceed 5 degrees or manufacturers recommendations, whichever is less.

5. All joints, penetrations & any exposed lifting holes shall be made smooth, so as not to retain debris. Base/sump shall be smooth to facilitate cleaning.

6. Unless otherwise specified or directed, install storm drain pipe in accordance with manufacturer's installation guidelines.

7. Couplings for connection of PVC to concrete or other non-compatible pipe shall be selected from the ODOT QPL consistent with the intended use for sizes up to and including 12-inch diameter.

8. After manhole channeling and prior to mandrel testing, TV inspection or final acceptance, flush and clean all sewers, and remove all foreign material from the mainlines, manholes and catch basins. Failure to clean all dirt, rock and debris from pipelines and manholes prior to TV inspection will result in the need to re-clean and re-TV the storm lines.

The Contractor will be required to pay for water used for such re-cleaning of storm lines.

9. Contractor shall conduct deflection test of flexible storm sewer pipes by pulling an approved mandrel through the completed pipe line following trench compaction. The diameter of the mandrel shall be 95% of the initial pipe diameter.

Test shall be conducted not more than 30 days after the trench…
