The Project's scope of work included the installation of drainage pipes to be in conjunction with
the installation of check valves in discharge pipes, temporary stormwater pump stations,
existing drainage structure modifications, and the installation of check valves where tidal
flooding has occurred or predicted to occur.
ln continued efforts to protect residents from tidal flooding throughout the City, the Public Works
Department requested an additional scope of work to the existing Agreement with Southern
(Change Order No. 1), which was approved at the June 11,2014 City Commission. Under
Change Order No. 1, Southern would continue to provide all necessary labor and equipment
needed, including additional engineering services, installation of the additional check valves,
drainage structures, the installation of temporary stormwater pump stations, and the removal of
existing exfiltration trenches. The cost associated with Change order No. 1 was $661,980.50,
plus a total Project contingency in the amount of $88,019.50, for a total construction cost of
$775,000.
As the construction progresses, additional concerns have been revealed and as such, the
Public Works Department is requesting a Chance Order No. 2 to the Agreement, for an
additional scope of work to include additional check valves, modification of drainage structures,
installation of drainage pipes, and a watermain replacement in order to complete the Alton Road
project.
COST ANALYSIS
Southern has submitted a cost proposal in the amount of $180,000 (ATTACHMENT) for
additional engineering services, a watermain installation, drainage pipe installation, check
valves for existing outfalls in various locations requiring protection from tidal flooding. The
proposal includes a construction cost of $180,000, plus a project contingency in the amount of
$30,000, for a total cost of $210,000. The proposal breakdown is as follows: $85,270 for the
force main repair at Belle lsle, $60,730 for additional check valve installation and $34,000 for
the water main installation on 14th Street.
This cost proposal has been submitted to the City's Public Works Department for further review
and recommendation. City staff reviewed the proposal and found that the amount was fair and
reasonable. We have priced the work through alternative methods including the FDOT Joint
Participation Agreement for Alton Road and the NJPA cooperative purchase but in both
instances, the costs were significantly higher. As a result, we are recommending this change
order.
CONCLUSION
The Administration recommends adopting the Resolution

Re: Proposal to Repair Overflowing Stormwater Forcemain on Belle Isle
Mr. Rivas,
As per your request, Southern Underground Industries has reviewed the plan excerpts you
provided and we visited the site to observe the overflow condition and surrounding area. It
appears that each time the stormwater pump station turns on the water is conveyed through
a24" DlP force main to a diffusion-type inlet approximately 100 feet east of the seawall on
the south side of the Venetian Causeway. From this structure to the seawall, the pipe
reduces in size from a 24" to an 18" DIP force main which connects with a concrete collar
to the existing 18" RCP outfall pipe. As you know, this constriction of pipe diameter
causes the stormwater under pressure to overflow through the manhole inlet cover in the
bike lane.
Our opinion is that the connection of an inlet to this forcemain system is not appropriate
given the volumes and pressures running through the pipe. It is our recommendation that
this inlet opening be eliminated, the 24" DIP force main connected to eh l8" force main
and to fill the structure with grout and abandon. This approach, however, will require for
the curb & gutter, and sidewalk, to be repitched from the bridge to the intersection
(approximately 150 LF) to allow for rain water to be conveyed to the nearest inlet around
the corner as there will no longer be an inlet at this location. The following scope of work
has therefore been considered.
SCOPE OF WORK: Labor, equipment, and material necessary to install:
24" 45 bends, a24" x18" Reducer, and sleeves as required. (see sketch)
Based on this scope of work, Southern Underground Industries proposes to complete this
work for a lump sum price of $851275.00 and we will need 3-4 weeks to complete all work.
Feel free to call me with any questions regarding this proposal. Thank you for the
opportunity.

Re: Proposal for Water Main Extension on 14th Street, from Alton Road East to Alley
Mr. Rivas,
Southern Underground Industries has reviewed the plans you provided and we have
prepared the following proposal. As per the plans and our discussions the following is a
general summary of the scope of work. Please note that due to the project completed by
Bergeron in this area, there is a portion of existing asphalt that is 14" thick. This proposal
includes saw cutting this asphalt and restoring with 12" of limerock and 2" asphalt patch
restoration.
SCOPE OF WORK: Labor, equipment, and material necessary to install, including:
Based on this scope of work, Southern Underground Industries proposes to complete this
work for a lump sumprice of $34,000.00 and we will need2-3 weeks to complete all work,
including testing, clearance, final clearance, connections, and restoration. Feel free to call
me with any questions regarding this proposal. Thank you for the opportunity.
