REMOVAL OF NUISANCE WATER

Remove nuisance water entering the trenches.

Nuisance water that can be removed through the use of sump or trash pumps is not considered dewatering.

Keep trenches free from water until waterlines, fittings, valves, sewer lines, manholes and other appurtenances are in place and sealed against the entrance of water.

Prevent all water, earth or any foreign material from entering any facility.

Keep trenches free from water until the facilities are in place, sealed against the entrance of water, and backfill has been placed and compacted above the water level.

LOCATE EXISTING UTILITIES

Field locate all existing underground utilities.

Utilize state “811” or “one-call” hotlines.

Contact all other utility owners not covered by the state “one-call” hotlines.

UTILITY CONFLICTS

Protect existing utilities from damage during excavation and backfilling operations.

Provide temporary support for existing water, gas, telephone, power, or other utility services that cross the trench until backfilling of trench is complete

MOVING FENCES AND MINOR STRUCTURES

Remove and reset culverts, drainage pipes or other minor structures that fall within the alignment of the new construction, to their original location and grade.

Visit the project site and determine actual conditions with regard to the existence of old car bodies, abandoned houses, fences, driveways, trees, stumps, brush, sidewalks, approaches, and other miscellaneous obstacles to construction.

Unless specifically referenced in a bid item, no separate payment will be made for the removal or replacement of these items.
