DISCUSSION:
The Fleet Maintenance Facility Project required design changes due to additional grading and paving, restroom wall tile changes, and fixture credit as summarized below:
Revised grading and paving: The original bid package did not provide for vehicle access to a secondary gate near the southwest corner of the site. Staff requested a change order from the contractor to regrade this area and extend the concrete pavement to the gate. The additional cost related to this change is $25,447.
Restroom wall tile changes: The restroom and shower tile material that was selected at bid time was discontinued. The architect has worked closely with the contractor to select a suitable alternative that minimizes cost increases. The additional cost related to this change is $1,201.
Fixture credit: Light fixtures were modified from L4 fixtures to L2 wall mount fixtures.
The modification resulted in a reduced project cost. The amount of credit issued for this change is -$2,256.
Doorframe and hardware changes: Future security measures require electric hinges and hollow metal doors to accommodate future wiring. This modification will allow the City to add a keycard system in the future. The difference between the cost of the original doors/hinges and the proposed doors/hinges is $1,993.
The additional work is to be billed at a cost not to exceed $26,385.
FISCAL IMPACT:
The attached Change Order No. 7 is in the amount of $26,385 and will be allocated to the Corp Yard AB1600 Fund (47.0%), Water, Sewer and Storm Enterprise Capital Funds (15.8%) and General Capital Fund (37.2%). The amended construction contract price is shown in Table 1.

On December 13, 2022, City Council approved the total cost of the Fleet Maintenance Facility Project which included $1,115,600 for construction contingency. Change Order No. 1 did not utilize the project contingency because the work was performed at the Wastewater Treatment Plant disposal ponds. The total remaining contingency after subtracting Change Orders No. 2 through 7 is $877,381.
