Task Order 20
Engineering Services for Evaluation of Boynton Beach
Boulevard Force Main Replacement.
A. Background
An existing force main between the City of Boynton Beach's West Water Treatment Plant
(WTP) and Lift Station (LS) 801 is a 30 year old cement-lined cast iron pipe. It appears that
the 10-inch diameter line has been installed at a depth of between 3 - 4 feet below land
surface and that much of it has been constructed under the travel lanes of heavily traveled
Boynton Beach Boulevard. The force main is approximately 5,000 in length, includes a canal
crossing, and crosses Military Trail. There are ten other lift stations that discharge into this
force main. The force main originates near the Platina development and terminates at a
manhole that is part of the LS 801 gravity system. The CITY has experienced failures at
various locations along the force main and suspects that hydrogen sulfide gas has
deteriorated the top section of the cast iron pipe. While repairs have been made, there is
ongoing concern for the integrity of the pipe and for its remaining life expectancy.
Additionally, the CITY relies on the force main to discharge reject water from their West
WTP during periods when the disposal well is being maintained. To this end, the force
main is critical to insure continuous operation of the CITY's West WTP.
The services proposed under this task order by CH2M HILL (CONSULTANT) will be
engineering services to evaluate the feasibility for a various options for the restoration /
replacement of the Platina force main on Boynton Beach Boulevard. CONSULTANT will
conduct an hydraulic evaluation of the system to determine its limitations in accepting
additional flow potentially provided from modifications to the CITY's West WTP. In
addition, CONSULTANT will perform a limited evaluation of alternatives for disposal of
concentrate from the West WTP when the deep injection well is unavailable (due to
maintenance).
B. Scope of Services
The specific services to be provided by the CONSULTANT are as follows:
Task 1 - Alternatives Evaluation for the Restoration / Replacement of the Platina Force Main
The CONSULTANT will develop a set of recommendations to correct the current force
main condition described above that will include financial and non-financial parameters.
To develop an informed solution, a hydraulic evaluation of the system will be required,
which would entail an analysis of the force main and gravity systems. The system to be
reviewed will include the Platina force main, the receiving gravity system, and the other lift
stations and force mains that tie directly into the Platina force main. A review of the
receiving lift station (LS 801) and current operations will be required to confirm that the
pumps have sufficient excess capacity to accommodate the additional flow. If the receiving
pump station requires upsizing, an hydraulic evaluation of the entire force main network
may be required under a separate task order.
TASK OROER 20 1
A ranking system will be developed to help determine which method of restoration or
replacement would best serve the utility. Factors for each option will include hard costs,
technical complexity, permitability, as well as non-cost factors such as potential impact to
adjacent community areas. The ranking system will assist the CITY with selecting the best
restoration / replacement alternative so the CITY can proceed with correction to the force
main and associated systems. The preliminary options that will be evaluated include the
following:
· Lining the existing Platina force main.
· Upsizing the existing Platina force main.
· Installing a new parallel force main along Boynton Beach Blvd.
· Installing a new replacement force main along Boynton Beach Blvd.
· Installing a new force main along Military Trail.
· Open-cut versus directional drilling.
· Install a new replacement force main along an alternate route to LS 801.
Task I includes the following specific elements:
· Develop uniform unit costs to be applied to various options to develop probable
construction costs for each option.
· Examine each of the options presented above and refine the extent of each option with
appropriate technical factors. Prepare individual cost estimates for each option.
Review the capacity and hours of operations for LS 801 that includes a series of ten
contributing lift stations and the gravity flows. Conduct an hydraulic analysis of LS 801
to determine whether sufficient surplus capacity exists to allow higher use of LS 801 for
the reject flows. The hydraulic model planned for this purpose will be similar as
previously used with LS 317 and the 356 FM. Apply this information to those options
that rely on expanded use of the LS 801 as a means to handle the reject water.
· Develop an option ranking system with construction costs as well as non-cost factors
that will be used to guide decisions for the recommended solutions.
Assemble and review the options ranking system with CITY staff to develop the final
top ranked options list for subsequent refinement. Develop an options ranking display
for use by staff for the elected officials.
Prepare and deliver 5 copies of a Summary of Findings Report with comparisons and
memorandum to the CITY containing the various options with specific focus on the top
three ranked options. The memorandum will outline the technical and non-technical
issues for the top three ranked options. The memorandum will also describe the
required design tasks needed to implement the top three ranked options.
The CONSULTANT will prepare a "Power-Point" based presentation for staff use to
acquaint and inform the community areas that may be affected with the recommended
options determined by the ranking system.
TASK ORDER 20 2
Task 2 - Evaluation of Concentrate Disposal Options
During Task 2, CONSULTANT will conduct an evaluation of alternatives for disposal of
concentrate from the CITY's West WTP. The back up is necessary to insure continuous
operation of the West WTP during periods when the deep injection well is being serviced.
This task does not include design or construction of the recommended solution. A similar
ranking system as developed for Task 1 will be used to guide the decision process. Factors
for each option will include hard costs and technical issues as well as non-cost factors such
as potential impact to adjacent communities and traffic, reliability, and controlling
authority. The ranking system will assist the CITY in selecting the an alternative that best
meets the needs of the utility and public. The disposal options that will be evaluated
include the following:
· Install a dedicated force main that connects to the primary force main at Congress
Blvd.
· Discharge the membrane reject to the County's wastewater system.
· Construct RO Train #3 to further reduce the volume of reject water
· Construct a new deep injection well for concentrate disposal and backup
C. Additional Services
CONSULTANT will provide additional services beyond the scope as authorized by the
CITY as an amendment or as a separate task order. Additional services may include, but
are not limited to, the following:
· Civil engineering design or design of options from the ranking system.
· Permitting services.
· Bid phase services and bid documents preparation.
· Services during construction.
· Survey and Geotechnical Services related the evaluation of the force main replacement
evaluation.
· Subsurface exploration and utility locations required to assist in the force main
evaluation and to locate points of conflict with existing utilities and proposed options.
· Services for a comprehensive hydraulic evaluation (modeling) of the entire gravity
system or other systems beyond the LS 801 service area.
O. Assumptions
The following assumptions have been made in preparing this scope of services and
compensation:
· The CITY will assist the CONSULTANT and provide applicable information, data and
operational information for the evaluation work.
TASK ORDER 20 3
The proposed hydraulic model will not be further calibrated or validated beyond that
work previously performed on the wastewater system.
The hydraulic model will be applied to LS 801 and the ten contributory lift stations and
gravity sewers in the LS 801 service area.
Other than the Platina force main, the existing piping and station infrastructure are
assumed to be in satisfactory condition.
The CITY will employ other outside consultants that may be necessary (survey,
Geotechnical, or utility verification finns) under separate agreement to the CITY.
E. Obligations of the CITY
· The CITY will provide the CONSULTANT access to the site.
· The CITY will provide the CONSULTANT with system data and flow information to
assist in the evaluation of the force main replacement and options under consideration.
· The CITY will provide the CONSULTANT with access to scaled plans showing the
routes, sizes and fittings for the associated piping.
