SUPPLEMENTAL AGREEMENT NO. 1
WHEREAS, a Professional Services Agreement was entered into between the City of Waterloo, Iowa,
(Client), and AECOM Technical Services, Inc. (ATS), of Waterloo, Iowa, dated June 26, 2017, for the repair
of thirty-seven (37) sanitary gatewells along the Cedar River levee system in Waterloo; and
WHEREAS, the Client and ATS now desire to enter into Supplemental Agreement No. 1 for additional
design services to create contract documents for two separate gatewell projects.

I. Project Description
The project consists of repairing, replacing and investigating thirty-two sanitary gatewells along the
Cedar River and Black Hawk Creek levee system in Waterloo. Pipe sizing through gatewells range

sanitary crosses through the levee. There is also approximately 1,400 feet of sanitary sewer
installation. The project utilizes State Revolving Fund (SRF) funding and necessary Army Corps
of Engineers and Iowa Department of Natural Resources permitting.
This project was originally bid in April of 2020 as one project. To allow for the funding of the project
to be spread over additional fiscal years, it was desired to separate the original project into two
smaller projects to be bid at different times. The first of the two projects will address the gatewells
where the replacement of the gate within the existing gatewell structure is required where
excavation is not planned. The second project will address the gatewells that require full
replacement of the structure and appurtenances where excavation is required. The second project
will also include installation of the proposed sanitary sewer.
II. Scope of Services
The Scope of Services will encompass and include detailed work, services, materials, equipment,
personnel and supplies necessary to create contract documents for the two projects discussed
above. The projects will each be divided into two phases. The first phase will include design
services, including the preparation of plans and specifications in a format suitable for City of
Waterloo lettings. The second phase will include construction -related services, which will be
determined at the time the services are needed.
Design Services
The Scope of Services for the Design Phase is further defined as follows:
Task 1 - Kickoff Meeting. With the City of Waterloo and ATS staff, a kickoff meeting will be
conducted to discuss scope of project, objectives and goals for the two projects.
Task 2 - Plans and Specifications. Prepare plans and specifications for each project. Plans will
include cover sheet, general notes, plan and profile sheets, site locations for work, gatewell details,
reference information of existing gatewells, site restoration items and details as necessary.
Specifications will include contract documents incorporating requirements from the City of
Waterloo. SUDAS specifications will be referenced. Required SRF documents necessary for
bidding the project will be included.
