WORK AUTHORIZATION NO. FOR CONSULTING SERVICES
PROJECT No. G/L CODE:
CHEN-MOORE PROJECT NO.: 492.015
PROJECT TITLE: Design Modifications and Rebidding of Water Treatment Plant Process&Control
Improvements
This Work Authorization, when executed, shall be incorporated in and shall become an integral
part of the Agreement for Professional Services dated September 10, 2020 between the Village of
Tequesta ("VILLAGE"), Chen-Moore & Associates ("CONSULTANT"), And Wright-Pierce,
Inc. (SUBCONSULTANT)hereafter referred to as the Agreement.
I. PROJECT DESCRIPTION
The VILLAGE owns,operates and maintains a Public Water System(PWS)No.4501438,which
provides potable water to the customers within the VILLAGE's water service area through
approximately 5,045 connections. The PWS generally consists of fourteen groundwater wells, a
water treatment plant (WTP)with two separate treatment trains, and over seventy-two miles of
water distribution mains ranging in size from 4-inch to 16-inch in diameter.
The PWS has a Florida Department of Environmental Protection (FDEP) permitted maximum
day operating capacity of 6.33 million gallon per day (MGD). The VILLAGE's South Florida
Water Management (SFWMD) Water Use Permit (WUP No. 50-00046-W), which expires on
October 31, 2031, allows the VILLAGE to withdraw up to 1,594 million gallons(MG)annually
with a maximum monthly withdrawal limit of 230.11 MG
The WTP generally consists of a 2.7 MGD sand filter treatment process, a 3.6 MGD reverse
osmosis(RO)treatment process,one 0.75 MG water ground storage tank(GST)and one 2.0 MG
GST for finished water storage, and two high service pump stations (HSPS). The HSPS pumps
finished water from the GSTs into the water distribution system. There are two HSPS, each
related to one of the treatment trains. Pumps 1 through 4 are vertical turbine pumps located
outside, near the 0.75 MG GST, and are each equipped with 40 HP motors. Pump 4 has an
adjustable speed drive. Pumps 5 through 7 are horizontal, split-case pumps, located in a pump
room next to the RO Process area. Pumps 5 and 6 are equipped with 125 HP motors, and Pump
7 is equipped with a 75 HP motor. Pumps 5 and 7 have adjustable speed drives.
WORK AUHORIZATION NO. 1 of 6
The Sand Filter treatment system was originally installed in 1977 as a GreensandTM filter for
iron removal. In 1982,the filter media was converted to sand/anthracite. In 2000,the VILLAGE
constructed the first reverse osmosis RO treatment train. The treated water from both treatment
trains is combined in a clearwell,prior to being pumped into the GSTs before distribution.
The SUBCONSULTANT provided design for energy savings and better operational control at
the WTP which translated to specific improvements to the treatment, SCADA, and pumping
systems. That design has been advanced to 100%. Following receipt of the 100% design and
bidding of said design, the VILLAGE identified modifications to the improvements of the
treatment, SCADA, and pumping systems. The VILLAGE has requested that
SUBCONSULTANT update the current construction documents to include the treatment,
SCADA, and pumping system modifications.
The following objectives summarize the modifications identified by the VILLAGE for
incorporation into the 100%design documents:
• Removal of the liquid ammonia sulfate chemical feed system
• Removal of the RO interstage booster pumps
• Removal of the GST bypass piping
• Removal of the post-clearwell flow meter
• Modification of the RO Building second-floor layout from individual electrical units to
a centralized electrical room
• Relocation of the transfer pump VFDs to the centralized electrical room
• Associated Electrical modifications related to the above changes
• Associated Instrumentation modifications related to the above changes
• Associated Architectural and Structural modifications related to the above changes
• Associated Civil modifications related to the above changes

proposed fee is inclusive of the construction services reduction detailed below. Budgets allocated
to individual tasks are interchangeable, allowing flexibility in the distribution of effort across tasks
as needed to complete the work.
The proposed design modifications will create some opportunity for savings in efforts by the
SUBCONSULTANT during the construction project, and though some of that benefit is reduced
due to project delays from the original anticipated schedule,SUBCONSULTANT is able to provide
a reduction in the expected construction phase services totaling $28,975. In order to provide this
reduction, it is expect that the following modifications are made to the original construction phase
services:
• The previously proposed 10 days for startup and testing are reduced to 6 days,as a result of
the removal of the interstage booster pumps and chemical feed system and the limitation of
WORK AUHORIZATION NO. 4 of 6
SCADA testing services to equipment associated with this construction contract only.
• An overall reduction is provided to the construction services phase associated with the net
reduction of equipment associated with the revised bidding documents.
