Scope of Services

The Scope of Services generally consists of preliminary design and related evaluations associated
with rehabilitation of the Elkhead Dam. The purpose of this project is to identify physical condition
issues and rehabilitation associated with both the ownership transfer of the dam/reservoir from the
Colorado Division of Wildlife to the City; and the subsequent design and actual implementation of
the items in need of rehabilitation. Those items are more fully described in the following scope of
work which includes:

1. Engineering Proiect Management. This includes general control and coordination of all eHort
needed to accomplish the scope of work; written and verbal communications; contract
administration; billings and cost accounting; schedule management; and periodic reporting.

2. Obtain. Review. and Summarize all Available Background Information. This will include use of
both established documentation and interviews with OWNER's personnel who have information
which may be of value. The objectives of this item are to identify the specific issues to be
addressed in the scope of work; to obtain all OWNER information; to bring CONSULTANT
knowledge of the project current to date; and to assure there is concurrence between the
OWNER and the CONSULTANT on the issues to be addressed and the level of detail.

3. Physical Inspection and Analysis of the Dam and Related Facilities. This includes evaluation of
the existing dam components by category as follows:

. Roadway and Spillway Bridge - The condition and conformance with applicable
standards will be addressed. This will cover the roadway geometry (width and plan
layout) roadway structural section (vertical and horizontal), bridge structure,
bridge/roadway transitions, access to dam components, drainage and roadway
vertical curve. An important issue here is what is needed to rehabilitate features and
who is the responsible entity.

. Maintenance - Identification of conditions which can be handled by routine
maintenance and what is currently needed to bring those conditions to an acceptable
level. This includes things such as rodent control, tree and root control, sufficiency
of riprap, vegetation coverage, and guard rail repair.

. Primary Outlet - Subaqueous physical inspection of the outlet structure is expected
to be necessary (versus inspection in the dry) and it is assumed operating personnel
will be present exercise the gate for observation by the inspector. The outlet pipe
will be inspected using closed circuit television from the downstream end after
external sealing of the gate by the diver. It is known that the primary outlet gate has
sealing and possible operational problems. Rehabilitation or replacement will be
evaluated keeping in mind the possible need to install screening devices in the
future. Flow and level monitoring devices will be evaluated and appropriate
modifications recommended consistent with State Engineer needs.
