Ken, attached is a draft of a suggested scope for the North Lake RFQ. It does not have the detail that a contract
scope would, but I thought you would like to have the responders fill in more details with their project approaches
in the SOQ. We didn’t discuss construction phase services, but I have both general rep and resident rep in here. I
know the City usually provides inspection, but, since I wasn’t sure, I thought it would be easier to take it out than
add it. Obviously, these are suggestions, so feel free to modify as you see fit to meet the City’s needs.
I talked with Steve Watters, who is an expert on 404 permitting issues, and he said that lowering the lake without
any construction effort in waters of the US should not be jurisdictional, but that it would probably be wise to let
the Corps know what you’re doing. He said that once lowered, any fill activity in the 22 feet should also be OK,
but that reshaping the perimeter and putting in hard edges,… would be jurisdictional. I assume that will be the
developer’s responsibilities rather than the City’s. You can see in the scope that it’s relatively vague on the issue
depending on coordination with appropriate stakeholders.
Let me know if you have any questions.
Thanks

City of Coppell
Lowering of North Lake
Proposed Scope of Services
BASIC SERVICES:
The City of Coppell desires to lower the conservation pool of
North Lake by 22 feet, from elevation 510 to 488. In order to facilitate this, a consultant
is needed to render the following professional services in connection with the project:
Preliminary Design of necessary improvements to the dam, including geotechnical
field exploration
Identification and Coordination of any environmental permitting requirements that
may be necessary
Assisting the City in coordinating with stakeholders in determining the final
configuration of the improvements and schedule for development of the project.
Final design of the improvements, including coordination with TCEQ for dam
safety.
Construction phase services for the improvements
Phase I) Preliminary Designand Permitting
- The first phase for the project will
consist of working with the Owner to develop the overall proposed configuration and
development schedule for the project, including:
1.Identify constraints and issues for the dam and lake that will be involved in the
development of the project and the lowering of the pool level, both upstream and
downstream from the dam. This will include coordinating with appropriate
stakeholders in the project for their input.
2.Develop appropriate hydrologic and hydraulic models for the drainage area, the
spillway, and the downstream channel.
3.Identify any environmental permitting requirements that may be necessary and
coordinate the application(s) and pursuit of necessary permits.
4.Develop a preliminary configuration for modification of the dam and spillway to
effect a 22 foot lowering of the reservoir, taking into account the identified
constraints and issues from previous tasks.
5.Provide needed geotechnical field exploration of the dam and spillway area as
appropriate for the proposed modifications.
6.Develop a recommended project development schedule for lowering the pool
level and constructing the dam and spillway modifications.
7.Prepare a cost estimate of the proposed configuration,
8.Prepare a preliminary design report describing the findings and recommendations
for this phase of the project.
Phase II) Final Design
- The final design phase will include the production of plans,
specifications, and contract documents for bidding and construction of the recommended
dam and spillway modifications and assistance with advertising, bidding and award.
Phase III Construction PhaseServices
- The services provided during the construction
of the recommended structures designed during Phase II, Final Design, include both
General Representation and Resident Representation.
-
General RepresentationAssist OWNER during construction in:
1.Conducting a pre-construction conference with the Contractor,
2.review construction submittals prepared by the Contractor
1.Maintain a project documentation system
2.Make visits appropriate to the stage of construction to the site to observe the
progress and the quality of work and to attempt to determine in general if the
work is proceeding in accordance with the Construction Contract Documents.
3.Coordinate the work of testing laboratories required for the testing or
inspection of materials
4.Interpret the drawings and specifications for OWNER and Contractor
5.Conduct a final review of the Project for conformance with the design concept
of the Project and general compliance with the Construction Contract
Documents
6.Provide “Record Drawings" to OWNER.
Resident Project Representation - Assist OWNER during construction by:
1. Furnishing the services of a Resident Project Representative to act as
OWNER’s on-site representative during the Construction Phase. The
Resident Project Representative will daily representation at the Project site
during the Construction Process.
