Winter Springs WTP No.1 HSPS Piping Replacement
Sawcross inc. Project Approach
OVERVIEW
Contractual Substantial Completion = 90 calendar days
Contractual Final Completion = 120 calendar days
Liquidated Damages = $500/day
Our success will be measured by the ability to work with residents and plant staff to accommodate
nighttime shutdown work with minimal disruptions from noise and without plant down time.
We have identified several project risks which include;
1) Underground utility conflicts
2) Existing water table and dewatering
3) Condition and exercise of existing valves
4) Lead time on special DI fittings and valves
5) Addressing the concerns of neighbors during nighttime connection tie-ins.
We plan to address these concerns in several ways;
1) Use the lead time of the ductile iron fittings to focus attention on extension exploratory
digging to help us identify;
a. Existing piping connections
b. Current water table and the need for additional dewatering measures
2) During the Temporary Facilities phase, our crews will work with plant staff to help identify
and exercise shut off valves to ensure proper operation prior to critical shutdowns
3) We will utilize the long material lead time to perform extensive locates and site preparation.
We recommend to extend the Full Notice to Proceed (NTP) until the valves and fittings have
been delivered to the site.
4) We will attempt to address neighbors with advance notice of intended nighttime shutdown
work. We have identified three critical dates at which nighttime activities will be needed. All
other construction activities can be addressed during normal working hours. In addition, we
will take extra measures to ensure minimal equipment is being used and materials are
stagged in advance as to keep equipment movements at a minimum during the evening.
PRE-CONSTRUCTION MILESTONES
We expect city staff to issue a Notice of Intent to Award (NOIA) or Notice or Award (NOA) to the
Contractor within the first 30 days after opening the bids. Either of these formal procurement letters
will help the Contractor to start the purchasing process with our vendors which includes the
procurement of the valves, ductile iron fittings, flow meter and chemical injection quill. We have

reached out to our vendors and they have informed us several fittings which will have a lead time of
8 weeks once the order is placed.
CONSTRUCTION MILESTONES
We have identified eight construction milestones.
1) Notice of Award / Notice of Intent to Award (NOA/NOIA)
2) Pre-Construction Meeting (start milestone)
3) LIMITED Notice to Proceed (LNTP) (start milestone)
4) FULL Notice to Proceed (NTP) (start milestone)
5) Ground Storage Tank Completion (finish milestone)
6) HSP Service Transition (finish milestone)
7) Contractual Substantial Completion (finish milestone)
8) Contractual Final Completion (finish milestone)
SUBMITTALS, PRODUCTION & FABRICATION
Our schedule indicates a critical path that is controlled by the lead time on several key ductile iron
fittings, specifically 14”, 20” and the 42”x 30” reducer. We propose using the lead time of the fittings
to our advantage with a start on exploratory measures.
TEMPORARY FACILITIES & SITE EXPLORATION
Erect our temporary staging areas and start exploratory digging to locate existing underground
utilities and identify utility conflicts and water tables at each of the five constructions phases.
Accomplishing this work in advance of the NTP will enable our crews to quickly complete each
construction phase. Crews will also work with plant operators to exercise all existing valves to
ensure isolated connections can be made. Remove permanent fence and install temporary fencing
to accommodate the new 42” WM.
PHASE I CONSTRUCTION
Crews will assess the potential for groundwater during the Temporary Facilities & Exploratory
Digging phase. Crews will first start the installation of dewatering measures, if needed. After which
crews will assemble the 20” & 14” piping above ground. Next, crews will start the installation of the
temporary chemical line for staging near the 20” WM. The trench will then be excavated, and
protective shoring measures installed. The concrete saddle will then be poured prior to the
installation of the line stop. The line stop will be installed and crews will cut and remove the existing
14” WM, drop in and install the pre-assemble 20” & 14” piping, swab, disinfect, and connect the
temporary chemical feed line and place GST-2 back into service. All of this will occur during a single
shift. The shutdown will occur during low use periods at the plant which we will assume to be
evening hours. All light towers will be aimed away from neighboring residents. Construction

equipment movements will be as minimal as possible, and operators will be encouraged to avoid
backup motions to reduced audible backups signals.
PHASE II CONSTRUCTION
Crews will start at the tie-in connection at the 20” tee for GST-2. Crews will stop short at the 45-
degree fitting before the 14” WM (to be placed out of service). We will schedule a shutdown for
GST-1 to occur during plant low flow operations, we will assume evening hours. Crews will cut,
remove and cap the existing 14” WM. Lower into place a prefabricated and pressure tested section
of pipe. Crews will then swab, disinfect, and place GST-1 back into service. The 20” BFV will be
opened and GST-1 placed back online.
PHASE III CONSTRUCTION
Crews will begin work to extend the previously installed chemical feed line to the new chemical
injection vault. Installation of the WM starting at the 30” BFV and working southeast towards the
road crossing and HSPS above ground header. Steel road plates will be installed at the crossing to
ensure access is always maintained to the plant. Crews will then Bac’T and pressure the line.
PHASE IV CONSTRUCTION
The pipe tie-in will be coordinated with plant staff during low-demand times, we assume to be at
night. Crew will isolate flow from HSP#2 and HSP #3 leaving HSP #1 online. Once this has been
achieved, crews will demo and remove suction lines to HSP #2 and HSP #3 and install the new
suction pipe, swab and disinfect, and connect to the new 30” header and place HSP#2 and HSP#3
back online.
The following day, crews will then shutdown HSP #1, remove the existing suction pipe and connect
the new pipe to the suction header, swab, disinfect and place HSP #1 online. Relocate the existing CL
meter and cap and remove the existing WM from service.
PHASE V CONSTRUCTION
Phase will involve the project restoration. Crews will spend the next 30 calendar days restoring the
plant driveway, installation of the permanent fence, sod restoration, and demobilization.
PROJECT CLOSEOUT
During project closeout, the owner will be issued all copies of testing paperwork and final project
record drawings while crews work to complete all punch list items.

CLOSING SUMMARY
Plant and neighborhood impacts are critical to this project. I hope we have demonstrated a plan that
will address issues of importance to the City of Winter Springs and to Sawcross. We stand confident
that our plan will bring success to all parties involved.
