EXHIBIT 1
SCOPE OF WORK
INDIAN RIVER COUNTY
BIOSOLIDS DEWATERING FACILITY AT INDIAN RIVER COUNTY LANDFILL
ADMENDMENT NO. 1 - ADDITIONAL DESIGN, PERMITTING AND GENERAL SERVICES
DURING CONSTRUCTION
BACKGROUND
Indian River County (County) Utility Services Department currently operates a centralized
dewatering facility located at the Central Region Wastewater Treatment Plant. The close
proximity of the existing dewatering facility to neighboring developments led the County to
explore moving the operation to the Indian River County (IRC) Landfill. The IRC Landfill is the
current disposal site for the sludge dewatered at the existing facility. Given the age of the
existing dewatering facility's equipment, a new facility was proposed to be located at the
Iandfill. The new dewatering facility is designed to include the necessary sludge receiving,
pumping, and tankage to meet the County' s needs as well as the needs of the private grease and
septage haulers within the County. The facility design is based on a twenty year equipment life
cycle. Dewatering equipment will be provided by a private contract operator with a five year
operating contract with renewal options in accordance with County policy.
In the process of designing the facility, design activities were redirected to include the following
items, not originally included in the Scope of Services:
■ Aeration system for holding tank mixing and phosphorus mitigation
■ Mechanical blowers for aeration system
■ Additional electrical equipment
■ Expanded Electrical/ Laboratory building
■ The location for the facility within the landfill was modified by the County to maximize
landfill airspace
■ Additional permitting requirements
The original facility design was modified to include additional equipment and systems to
address the County's concerns regarding the potential for phosphorus release from biosolids in
the holding tanks as well as to mininze dissolved phosphorus content in the wastewater
discharge from the facility. The County's West Regional Wastewater Treatment Plant will
receive the process wastewater from the dewatering facility. The WWTP' s operations permit
includes a phosphorus limit as a discharge condition which was required to be taken into
account during the design modifications.
Additionally, the design effort and associated contract drawings for the wastewater force main
and water main extension were not included under the original scope of services. The need for
this effort was identified during the preliminary design stage and is necessary due to the facility
location within the landfill site.
1 jei 49 doc
The number of permits included under Task No. 2 was increased as additional permitting needs
were identified during preliminary design of the facility. Additional permits were prepared and
submitted that were not included in the original scope of services. These additional permitting
efforts include Notice of Intent to Use a General Permit to Construct Wastewater
Collection/Transmission System, Notice of Intent to Use a General Permit to Construct Water
Main Extension, and Title V air construction permitting determination.
The inclusion of additional systems/ equipment as well as the expansion of the Electrical/
Laboratory budding under the design tasks will also result in a longer anticipated construction
period and require additional review and processing efforts under Task 5 .0, General Services
During Construction. The following describes the modifications to the original Scope of Services
in greater detail.
SCOPE OF SERVICES
CDM will provide additional engineering services related to Preliminary and Final Design and
Permitting Services for additional engineering efforts required to complete the design of the
dewatering facility at the current revised location within the landfill. The additional services
will also include the additional operating equipment and processes not included in the original
scope of work. The intent of this Amendment is to provide additional funding for the upper
limit of Tasks 1, 2, 3 and 5. The additional services included in this Amendment are described
in the following Tasks.
Task 1.0 Preliminary Design
This task originally provided for the preparation of a Preliminary Design Report including
performing topographic survey and geotechnical services, establishing of necessary design
criteria, identifying specific permitting requirements, and preparation of a preliminary design
level opinion of probable cost.
During preliminary design of the facility, several modifications to the design were requested
and others were identified as necessary to mitigate for potential phosphorus releases in the
biosolids holding tanks. A diffused aeration system and mechanical blowers for holding tank
mixing and aeration were added to the design to attenuate this potential and control dissolved
phosphorus discharges from the facility.
Additionally, the location of the facility within the landfill was changed from a five acre site
originally proposed to a smaller site to maximize landfill airspace. The change in location
placed the facility farther away from connection points for water and wastewater utilities
required for the facility, causing a longer pipeline distance that previously anticipated. The
change in location resulted in additional effort for design and drawing preparation as well as
cost for additional surveying services for the longer utility piping routes.
The modifications to the design during the preliminary design phase resulted in approximately
twice the number of drawings originally included in the scope of services and associated
budget. The requested budget amendment for Task 1 .0 is presented in Table 1 . The projected
project labor disaggregation is provided in Table 2.

Task 2.0 Permitting Services
This task provides for the preparation of necessary permit applications, meetings, and
negotiation with regulatory agencies and preparation of responses to Requests for Additional
Information (RAI) by County Planning and Zoning Department. During preparation of the
preliminary design, additional FDEP permit requirements not included in the original scope of
services were identified. The additional permits included:
■ Notice of Intent to Use General Permit for Construction of Wastewater
Collection/Transmission system,
■ Notice of Intent to Use General Permit for Construction of Water Main Extension, and
■ Title V Air Construction Permitting determination
Permit applications for the identified General permits were prepared for County staff and
submitted to FDEP by CDM. CDM conducted a regulatory review for Title V Air permitting
requirements and submitted a letter of determination to FDEP Title V Air Permitting for the
facility. The preliminary response from FDEP indicated that an Air Construction permit would
be required for the facility' s emergency generator and did not address permitting requirements
for the facility's odor control system. Upon further review of the relevant regulations by CDM
and additional communications with FDEP, it was determined that Air Construction permits
would not be required for the emergency generator or the odor control system. A follow up
letter indicating the above and withdrawing the initial request for determination was submitted
to FDEP by CDM.
A revision of the county site plan application was also required due to a miscommunication
from the County Planning and Zoning Department. The site plan application had to be revised
from application for Administrative Approval to application for Major Site Plan Review which
required preparation of a new application, additional drawing submittals and additional
meeting time. The requested budget amendment for Task 2.0 is presented in Table 1 . The
projected project labor disaggregation is provided in Table 2.
Task 3. 0 Final Design
This task provides for the preparation of final design and bid ready documents for the biosofids
dewatering facility.
■ Aeration System for holding tank mixing and phosphorus mitigation
■ Mechanical Blowers for Aeration System
■ Expanded Electrical/ Laboratory Building
■ Water and wastewater pipeline
The number of drawing sheets included under final design has increased from 45 sheets
originally specified to 74 sheets to account for modifications to the design during the
preliminary design phase. The requested budget amendment for Task 3.0 is presented in Table
1 . The projected project labor disaggregation is provided in Table 2.
Task 4.0 Bidding Assistance Services
(No change in this Amendment)

Task 5.0 General Services during Construction
Additional general services during construction are anticipated as a result of the design
modifications described above. The additional services will provide for additional shop
drawing review, responses to RAIs, inspections, testing and other related work associated with
the additional systems and equipment included due to the modifications to the facility under
preliminary design. The requested budget amendment for Task 5.0 is presented in Table 1. The
projected project labor disaggregation is provided in Table 2.
