NV Energy obtained bids from three local contractors. The low bid was $299,883.28, which was over the original estimate by $85,441.28. During the course of construction multiple unforeseen issues arose with the undergrounding of the conduits. These unforeseen conditions caused change orders in the amount of $108,437.69. Staff has reviewed the change orders with NV Energy and determined the City is only responsible for $54,682.95 of these change orders. A summary of these change orders is attached for the Councils review.

The total contracted construction cost related to the City of Sparks at the end of the project was $354,566.23. NV Energy’s cost to install the new wiring was estimated $240,283 in January 2011. NV Energy’s portion of the construction did not take place until Dec. 2012 thru Feb. 2013. During this time they had an increase in labor, transportation, and overhead cost.
