rVTRUCKEE DONNER
Public Utility District
Memorandum
To: Board of Directors
From: Neil Kaufman
Date: July 12, 2004
Subject: Acceptance of the Coachland 1-80 Undercrossing Project
1. Why this matter is before the board:
Construction of the Coachland 1-80 Undercrossing project is complete. Filing of a Notice of
Acceptance and consideration of a closeout change order are necessary.
2. History:
The Coachland 1-80 Undercrossing was awarded to Advanced Asphalt at the May-17,:2003
Board Meeting. This was a joint project with the Truckee Sanitary District (TSD) that involved
installation of new water and sewer pipes inside an existing casing underneath Interstate 80.
TSD agreed to serve as the lead agency on the project and was responsible for preparation of
the Contract Documents and administration of the project during construction.
The total Bid Price for the project was $144,200 with the District's share at $72,450. The
presentation to the Board also noted some additional costs related to field testing and inspection
and administration performed by TSD for this project. Those costs were estimated at between
$5,000 and $10,000.
3. New information:
The project has been completed and the water pipeline is in service. TSD has submitted an
invoice to the District for the District's share of the project.
I am requesting a change order to cover two items not included in the original Bid Price of
$72,450.
1) TSD has indicated a cost of $3,850.13 as the District's share of design, inspection
and administration costs.
2) During construction, it was discovered that the existing casing is not flat but has a
high point located somewhere underneath the 1-80 pavement section. In an attempt
to minimize the impact of this high point, TSD had to modify the project to remove
the casing spacers and temporarily support the sewer pipe while the entire casing
was filled with a concrete slurry. This resulted in a $2,317.24 cost to the District.
4. Recommendation:
I recommend that the Board:
1) Authorize a filing a Notice of Completion with Nevada County accepting the
Coachiand I-80 Undercrossing project as complete.
2) Authorize a payment of$78,617.37 to TSD to cover the District's share of the project,
along with the two change order items discussed above.
