COMMISSION ITEM SUMMARY
Condensed Title:
A Resolution Approving And Authorizing The Mayor And City Clerk To Execute A Change Order To
David Mancini & Sons, Inc., For Additional Engineering Services, Drainage Structure Modification,
Drainage Pipe, Storm Water Pump Station, Pollution Control Structure, Milling And Repaving And Water
Main Replacement For The Biscayne Point Neighborhood Right-Of-Way Improvements Project, As Part
Of A Flood Mitigation Project On Crespi Boulevard, For A Total Construction Cost Of$3,550,876.
Key Intended Outcome Supported:
Ensure value and timely delivery of quality Capital Projects.
Supporting Data (Surveys, Environmental Scan, etc.): N/A
Item Summa /Recommendation:
In preparation for the October 9 King Tides (an especially high tide event that occurs twice a year,
when there is alignment of the gravitational pull between sun and moon), Public Works staff conducted
a field inspection throughout the areas that are known to be affected during this event. Initial flooding
was observed on Crespi Boulevard, from 80" to 84" Streets. To alleviate the flooding, staff utilized
water pumps and installed temporary plugs; however, a more permanent solution is required.
CURRENT STATUS
The Biscayne Point Neighborhood Right of Way Improvement Project is currently in the process of
being closed out. One of the intents of the project was to correct the storm water drainage within the
neighborhood, but after further assessment, additional improvements need to be made, includin
drainage on Crespi Boulevard, from 79" Street to 84" Streets, and a water main replacement, from 80
to 85th Streets.
The Public Works staff has requested an additional scope of work from David Mancini & Sons, Inc.
(DMSI) that would include: the replacement of a water main in Crespi Boulevard, the installation of a
new storm water collection system in Crespi Boulevard and construction of a pump station at the 81St
Street End.
The proposed pump station would be designed to fit the City's criteria and would include a pollution
control system and outfall that meets permit requirements. At the completion of this underground work
on Crespi Boulevard, the road sections impacted by this work would be milled and a new asphalt would
be overlaid. The storm water pump system would be functionally complete by April 2015,just in time to
address the expected flooding during the Spring High Tides.
COST ANALYSIS
DMSI has submitted a cost proposal in the approximate amount of $3,000,000 (Attachment) for
drainage and $536,376 for water mains. The City's Public Works Department has reviewed the
proposal and deems the amounts to be reasonable. During review there were deficiencies noted that
would make the work inconsistent with the latest drainage criteria. We have discussed the deficiencies
with DMSI and increased the contract for a total of$3,550,876, which includes a 10% contingency.
