As part of the improvements associated with the Nelson Dam Removal project Phase 1, additional work was required of the contractor, Northbank Civil and Marine, Inc.:
- Modifications were necessary to the utility building to accommodate the installation of the duplex strainer and valving outside of the Utility Building, where previously designed inside the building, due to the size of the strainer and valve assembly. In addition, a roof extension was provided over the equipment. Installing the equipment outside of the building provided necessary work space within the electrical/mechanical room.
- Improved seeding mix for the flood plain restoration area was required due to the time of year that the seeding took place.
- Additional handrailing and walkway grating was necessary for employees to safely access and operate a new gate valve.
The total cost of Change Order No. 6 was $102,252. |
