Agenda 06/09/2020 Item #16C3 (Change Order #14 to #16-6638 w/Mitchell & Stark Const.)06/09/2020
EXECUTIVE SUMMARY
Recommendation to approve Change Order No. 14 for Agreement No. 16-6638 with Mitchell &
Stark Construction Co., Inc., to balance contract quantities in the Vanderbilt Drive Cul-de-sacs
Public Utility Renewal Project (Projects 70122 and 60122), authorize the necessary budget
amendment and authorize the Chairman to sign the attached Change Order.
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 Agreement 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. (See Attachment 1 - project
map.)
The project reached final completion on March 23, 2020. Change Order No 14 includes a reconciliation
of pay items from the schedule of values for water, wastewater and stormwater. The allowances do not
have the necessary funds to cover all of the exceeded quantities, therefore, the difference will be covered
by the remaining quantity balances in bid line items.
An additional $160,000 is required to fully cover the costs of the additional stormwater quantities under
Change Order No. 14 and an upcoming final change order to process the final stormwater work directives.
FISCAL IMPACT: A budget amendment is required to transfer funds, in the amount of $ 160,000,
within the Stormwater Capital Fund (325) from Project 60139 to Project 60122.
GROWTH MANAGEMENT IMPACT: This project meets current Growth Management Plan
standards to ensure the adequacy and availability of viable public facilities.
LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires majority vote
for Board approval. -SRT
RECOMMENDATION: To approve attached Change Order No. 14 for Contract 16-6638 with Mitchell
& Stark Construction Co., Inc., to balance quantities in the Vanderbilt Drive Cul-de-sacs Public Utility
Renewal Project (Projects 70122 and 60122), authorize the necessary budget amendment and authorize
the Chairman to sign the attached Change Order.

modified to leave in place the existing gravity sewer between manholes
VD-4 and VD-3. This issue was related to discovering that the existing
drainage was two (2) 3’X7’ box culverts instead of two parallel 36" RCP,
as originally contemplated. Due to the depth, and inability to properly
support the culverts while crossing under them by means of open cut, it
was determined that the existing sewer would be left in place. Refer to
RFI #41 for additional information. This line item will be paid with
remaining amount from Item 3.28 - Furnish and Install Precast
