Invoice Description
CHANGE ORDER REQUEST
Additional Excavation Required for Additional unknown Lateral Tie-In’s.
Per the terms and conditions of the original contract, this change order request is being submitted for additional excavation work associated with unforeseen lateral tie-ins discovered during construction.
At the time of bidding and contract execution, the locations and direction of the existing service lateral tie-ins were unknown. During construction operations, it was determined that multiple lateral connections originate from the east side of the main line, requiring additional excavation holes and access points beyond the original project scope. This is for #5 additional tie-in’s.
The original contract specifically states that any additional excavation required due to unforeseen conditions or additional lateral tie-ins shall be addressed through a change order.
Scope of Additional Work
Additional potholing/excavation to locate east side laterals Additional excavation pits required for reconnecting service laterals Labor, equipment, and restoration associated with the added excavation work Safety measures related to the additional excavation operations Reason for Change
Existing lateral tie-in locations and orientations could not be verified prior to construction and were not identified in the contract documents. Field conditions revealed that additional laterals approach from the east and west side, necessitating additional excavation work not included in the original contract amount. Tie-In’s to the main line are also 6” which is larger than normal 4” design.
