Agenda 11/12/2019 Item #16C 9 (Budget Amendment for Vanderbilt Dr Cul-dw-sacs Public Utilities Renewal)11/12/2019
EXECUTIVE SUMMARY
Recommendation to authorize budget amendments in the amount of $911,912.93 for the Vanderbilt
Drive Cul-de-sacs Public Utilities Renewal, Project Number 70122.
OBJECTIVE: To provide reliable, sustainable, and regulatory compliant services to the customers along
Vanderbilt Drive and the 14 adjacent Conners Subdivision neighborhood cul-de-sacs by replacing and
refurbishing the water, wastewater and stormwater infrastructure in coordination with the Wastewater
Basin 101 Program and the Vanderbilt Beach aerial to underground utility conversion.
CONSIDERATIONS: On July 12, 2016 (as Agenda Item 11D), the Board approved Contract No. 16-
6638 to Mitchell & Stark Construction Co., Inc., for the Vanderbilt Drive Cul -de-sacs Project; which
included the replacement of water, wastewater and stormwater infrastructure. Attachment 1 - Project
Map.
The Vanderbilt Drive Cul-de-sacs Public Utilities Renewal Project achieved substantial completion on
October 25, 2019. All water and wastewater utility work has been complete and operational since
October 10, 2019. The project installed over 19 miles of water, wastewater and stormwater pipe,
rehabilitated four wastewater pump stations, and relocated two wastewater pump stations. 74% of the
project streets have the second, final layer of asphalt applied; one layer has been applied to the remaining
streets. To date, approximately 496 driveways have been restored. To complete the project, driveway
restoration is required at approximately 13 Vanderbilt Drive residences and 51 cul-de-sac residences, and
swales need to be graded and sodded on Connors, Seabee, Germain and Seagull Avenues, as well as on
small sections of Vanderbilt Drive. In addition, the final phase of the Municipal Service Taxing Unit
(MSTU) underground electrical activation is anticipated to complete by the middle of November and the
remaining poles scheduled to be removed prior to year-end.
A budget amendment is required for the following reasons:
Contractor Fixed Costs: On September 11, 2018 (As Agenda Item 16.C.9) the Board approved Change
Order No. 5, which added $481,571.05 in associated contract fixed costs for 310 additional days. The
forecasted amount was determined by an average negotiated “burn rate” based on costs to date. Fix ed
costs included: maintenance of traffic, rental of lots used for material staging, dumpster rentals, porta pots
rental, geo-seismic services, asphalt paving and labor. When the contractor invoiced the County for fixed
costs, actual invoices were typically higher than the forecasted burn rate. Therefore, the change order
amount was not sufficient to cover fixed costs beyond May 23, 2019 and an additional forecasted amount
of $408,000.00 is needed to cover fixed costs after that date to completion. This amount is based on a new
burn rate calculated from invoices paid to date. This cost will be included in a future change order.
Additional Driveway Quantities: Per Contract 16-6638, line items that exceed more than 25% of the
original quantities are subject to unit price negotiation. The quantities for brick pavers exceeded more
than 25% due to restoration of driveways extended beyond the right of way line for several unforeseen
conditions such as slope correction issues due to modifications to the road design, and installation of
sanitary sewer laterals on private property to eliminate existing vitrified clay pipes. Additionally, several
new houses were constructed or renovated since the start of this project. In total, 6,240 additional square
yards of brick paver driveway restoration has been or will be required. These additional quantities were
not included in the original contract and are being added now. The total amount needed over existing
project funds for driveways is $503,912.93. This cost will be included in a future change order.
Combined, the total amount needed for fixed costs and driveways is $911,912.93. No further funding for

fixed costs or driveways are anticipated for the remainder of the project; however, there will be other
additional quantities that exceed 100 percent and outstanding work directives that will be reconciled at the
end of the project.
FISCAL IMPACT: Funding is available in, and is consistent with, the FY2020 Capital Budget
approved by the Board on September 19, 2019. The sources of funding for the budget amendment are the
Water Capital Fund (412), the Wastewater Capital Fund (414), and the Stormwater Capital Fund (325) as
distributed below.
