Consider Action to Approve Change Order #3 to Flow-Line Construction, Inc., for the Construction of the Vitruvian Phase 5 Public Infrastructure Project Increasing the Construction Fee, and Authorize the City Manager to Execute the Change Order in an Amount Not to Exceed $58,498.

BACKGROUND:

Change Order #3 addresses changes due to unforeseen field conditions found during construction or that were requested by the Town. The change order amount is based on contractor's unit costs.

On January 10, 2017, Council approved a contract with Flow-Line Construction, Inc. (Flow-Line) for the construction of Vitruvian Phase 5 public infrastructure. The scope of work for Vitruvian Phase 5 public infrastructure includes a new public roadway and the associated streetscape and utility improvements along the east right-of-way line of Marsh Lane and the north right-of-way line of Vitruvian Way. Construction services for the new public roadway include water, wastewater, storm drainage, paving, electric duct bank, telecommunications duct bank, miscellaneous conduits, landscaping, irrigation, and streetscape improvements.

Improvements along Marsh Lane include the extension of water, wastewater, storm drainage, and gas main improvements along with streetscape, landscaping, and irrigation modifications. Improvements along Vitruvian Way include the addition of parallel parking spaces to the existing street section along with streetscape, landscape, irrigation and miscellaneous utility improvements from the Marsh Lane intersection to the existing Ponte Avenue intersection.

The following additional items are included in Change Order #3:

Sidewalk removal and replacement
Asphalt removal and replacement
Concrete pavement removal and replacement
Curb and gutter removal and replacement
Flexible base removal and replacement
Water line removal and replacement
Irrigation sleeves
Tree replacement

Change Order #1 approved a $24,939.81 cost increase and added 55 days for quantity and material modifications and the Westgate Lane schedule coordination.

Change Order #2 approved a $45,192.56 cost increase for quantity adjustments. There was no change in contract time for this Change Order.

Change Order #3 will increase Flow-Line's construction contract value from $3,893,205 to $3,951,703.37 and will add 180 days to the contract duration.

Funding for these improvements is from the May 2012 Bond Funds (included in Proposition 1). The project costs were budgeted in Fiscal Year 2019, and there are enough funds to cover known costs.

RECOMMENDATION:

Administration recommends approval.
