SUPPLEMENTAL AGREEMENT NO. 3
WHEREAS, a Professional Services Agreement was entered into between the City of Waterloo, Iowa,

additional design services to create contract documents for two separate gatewell projects; and
WHEREAS, the Client and ATS entered into Supplemental Agreement No. 2 on April 19, 2021, for

WHEREAS, the Client and ATS now desire to enter into Supplemental Agreement No. 3 for construction -

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
in size from 6" to 60". The project also includes replacing existing valves with gates where the
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 project (Phase I) was constructed to address
the gatewells where the replacement of the gate within the existing gatewell structure is required
where extension excavation was not needed. The second project (Phase II) will address the
gatewells that require full replacement of the structure and appurtenances where extensive
excavation is required. Phase II will also include installation of the proposed sanitary sewer.
This supplemental agreement provides construction -related services for the Phase II project.
II. Scope of Services
The Scope of Services will encompass and include detailed work, services, materials, equipment,
personnel and supplies necessary to provide construction -related services for the Phase II project
and associated engineering assistance to the City for the SRF process required for the project.
The Scope of Services is further defined as follows:
Task 1. Conduct a preconstruction conference attended by representatives of the Contractor,
Client, Consultant and affected utilities.
Task 2. Provide construction staking for horizontal and vertical controls for the project.
