Re: Change Order #3 Proposal, Vertical Well Valve Trial on Meridian Ave,
Additional Backflow Valves on Belle Isle and Along Indian Creek Dr from 24 ST to 4l
ST
Mr. Egemba,
As per your request, Southern Underground Industries has reviewed the field conditions
and made some preliminary assessments of required scope of work in the following areas
and we have prepared the following proposal. Additional measures are necessary to protect
the following areas from Tidal Flooding conditions.
As per the attached breakdown, we propose that the following scope of work be added to
the City Wide High Tide Mitigation Project.
between 8th Street and 14th Street. As per our previous discussions it is
evident that tidal upflow from existing gravity drainage wells is contributing
to flooding conditions and we propose to reduce this added backflow by
installing a drainage backflow valve and grate in the vertical position on the
existing casings as per the attached detail.
investigation we found that there are 2 existing outfalls which are
contributing to the tidal flooding conditions on Belle Isle. These can be
resolved via installation of backflow valves. One location will require
installation of a structure within the easement to facilitate valve installation.
Street to 41 Street. Although more perrnanent solutions are in planning by
FDOT, we propose to install approximately l9 valves along the Indian
Creek outfalls to temporarily mitigate the tidal flooding conditions in this
area until a more permanent solution is reached.

areas, additional funds are required to supplement backflow installation
efforts in several areas including Monad Terrace, 59 Street on East side of
Alton Road, and additional of top slab modification for 24" valve
installation on 48 ST.
Based on this scope of work and as per the attached detailed breakdown, Southern
Underground Industries proposes to complete this work for a lump sum price of
$417,308.83 and we would recommend that a l0olo contingency be added to this change
order for unforeseen changes which would require resolution, bringing the total proposal
amount to $459,093.71 and will need 3-4 weeks to procure the necessary materials to
begin work which should take approximately 30-45 days to complete. Feel free to call me
with any questions regarding this proposal. Thank you for the opportunity.
Sincerely,
Southern Underground
