SCOPE OF SERVICES
CITY OF CLERMONT, FLORIDA
EAST SIDE WATER RECLAMATION FACILITY
EWRF RIB RERATE
I. PROJECT DESCRIPTION
The City of Clermont (City) owns and operates the East-Side Water Reclamation Facility (EWRF) located
at 3335 Hancock Road. The facility has a Florida Department of Environmental Protection (FDEP) rated
capacity of 4.0 MGD annual average daily flow(AADF) and is considered a Category II, Class B facility. In
dry weather, the City uses the Public Access Reuse (PAR) for residential irrigation as the primary means
of disposal. For wet weather and reject conditions, rapid infiltration basins (RIBs) serve as a backup to the
City's PAR. There are a total of fifteen (15) RIBs located onsite with a total wetted area of 4.76 acres having
a permitted capacity of 0.750 MGD AADF. Future improvements to the EWRF include expansion from 4.0
MGD AADF to 9.0 MGD AADF. In order to expand the EWRF, the RIBS must be rerated to accommodate
wet weather and reject conditions at the expanded capacity.
Andreyev Engineering Inc. (AEI) performed a RIB Rerating and Feasibility Assessment and determined the
RIBs to have sufficient storage and disposal capacity for wet-weather and reject water at the buildout
capacity of 9.0 MGD. AEI completed soil testing, ground water modeling, and load testing to support the
Florida Department of Environmental Protection (FDEP) Permit Modification which includes replacement of
the current 15-cell system with 4 larger cells and construction of two(2) new ground water monitoring wells.
This proposal is for professional services associated with a design, bidding, and construction management
of the EWRF RIB Rerate.
The tasks to be completed for this project are further described herein and will be performed in accordance
with the City/Tetra Tech Continuing Contract and Agreement for Professional Engineering Services for
Public Works Projects dated December 9, 2014.
II. SCOPE OF SERVICES
Tetra Tech shall provide professional engineering services necessary for design, bidding and construction
of the proposed EWRF RIB Rerate. Services included are described in the tasks below.
Task 1 —Final Design
The final design will result in preparation of the bid documents, engineering drawings and
specifications, which will be submitted to the City for review at 60-, 90-and 100-percent completion
levels. Three (3) sets of drawings and specifications will be provided to the City for each review.
A review meeting will be held with City following each submission. To ensure proper design of the
facilities,Tetra Tech will obtain approval from the City for any substantial changes in the preliminary
design prior to incorporation in the final design. Tasks to be completed during this phase are
summarized below:
1. Attend a kick-off meeting/site visit with City Staff to finalize concepts.
2. Provide a limited topographic and horizontal survey in sufficient detail to facilitate the
design of the contemplated improvements. The location of underground facilities will
be based on record drawings and discussions with City Staff. Soft-digs are not included
under this scope.

3. Prepare design drawings at the 60-, 90-, and 100-percent completion levels for
competitive bidding.
4. Prepare a comprehensive project manual that contains bidding, contractual documents
and technical specifications for competitive bidding. The project manual and its
contents will be formatted in accordance with the Construction Specification Institute
(CSI).
5. Attend project review meetings at the 60- and 90-percent completion levels. City
comments compiled at each review meeting will be incorporated into each subsequent
submittal.
6. Cost estimates will be included with the 90% and 100% submittals.
Task 2—Bidding Assistance Services
Upon advertisement of the project by the City, Tetra Tech will assist the City with bidding of the
project and will complete the following tasks.
1. Provide electronic copies of the bid documents for City to issue.
2. Attend one (1) pre-bid conference and one (1) site visits with prospective bidders.
3. Prepare and issue addenda, as approved by the City, containing clarifications or
technical revisions that become apparent during bidding.
4. Review and tabulate bids, evaluate the low bidder's qualifications, and make
recommendations regarding award of the contract.
5. Conform the construction documents at the end of the bidding phase to reflect any
changes to the project design, construction drawings or specifications caused by
addenda to bid packages or changes initiated by the City.
Task 3—Permitting & Construction of the Ground Water Monitoring Wells
The following task will be completed in accordance with the FDEP permit requirements.
1. Complete the installations of the two groundwater monitoring wells required under the
permit revision. Well construction will be supervised in the field by a registered
professional geologist. The wells will be permitted through the St. Johns River Water
Management District (SJRWMD) and well completion reports will be prepared and
submitted to the SJRWMD and the FDEP. Prior to well construction a standard
penetration test boring will be conducted at each well location, as required by permit,
in order to properly design the screen/filter section and select the appropriate depth
interval.
Task 4—Construction Administration Services
During the construction phase of the project, Tetra Tech will perform the following tasks.
1. Prepare for and attend at one (1) preconstruction meeting.
2. Attend six (6) periodic progress meetings and observe progress of the construction
after the meetings.

construction, fill placement, clay core installation and other periods of the work as
determined by the geotechnical engineer.
7. After successful demonstration tests and upon written request by the contractor,
conduct a substantial completion inspection of the Project with the City and distribute
a punch list of observed deficiencies to be completed by the contractor prior to the final
completion date. The project will be certified substantially complete only if the work is
sufficiently complete in accordance with the contract documents, so that the work can
be utilized for the purposes for which it is intended. Upon written request by the
