1. EMPLOYMENT OF CONSULTANT
The County hereby agrees to engage Consultant and the Consultant hereby agrees to perform
the services hereinafter set forth.
2. SCOPE OF WORK
Section 1 - PROJECT SPECIFIC INFORMATION
1.01 Planned Improvement
Weld County Road 13 is classified as a major arterial. The general planned improvement
is to design and construct a two lane roadway that consists of 12' paved lanes, 10'
shoulders (8' paved — 2' gravel) for the three mile section of gravel roadway with
consideration for the ultimate section.
1.02 Project Goals
Weld County has established the following design goals for the project:
Provide preliminary design for the ultimate roadway section consisting of 4-12' paved
lanes, 12' paved right turning lanes, 16'-26' paved center left turn lanes, 6' paved bike
lanes, curb &gutter and 8' concrete sidewalks.
Provide final design for the interim roadway section stated in Section 1.01 above.
Determine road drainage requirements.
WCR E 13,from WCR 2 to WCR 8

Design safe, adequate, and economical waterway crossing structures along the
project, based upon the interim section, including any irrigation facilities that may be
impacted.
Design safe intersections, driveways, and field intersections onto the new roadway.
Identify right-of-way requirements for individual parcels. Also identify easements
necessary for utility relocations and/or slope construction.
Increase the capacity of WCR 13
1.03 Project Location
This project is located in the southwestern portion of Weld County on WCR 13,
approximately 4 mile south of the Town of Dacono.
1.04 Construction Cost
The construction cost is to be determined by the Consultant.
1.05 Work Duration
The Consultant shall complete the Design Services defined in the Scope of Work, Section
7, within 200 calendar days from the date of Authorization to Proceed as described in Part
1, Section 1.07, of the RFP, exclusive of all days lost for review and approved by the
County. All days lost for review shall be documented by the Consultant and submitted to
the County for consideration.
For each calendar day that the Work is incomplete after the time specified or as adjusted
and approved by County in writing, a sum of $200.00 may be deducted from moneys due
to the Consultant as liquidated damages. This sum is fixed and agreed upon between the

a. Alternatives Analysis.
Develop Alternatives
Develop an agreed number of alternatives which will satisfy the
operational requirements of the project. When required, conceptual
layouts will be developed for major structures for each alternate, which
shows satisfaction of the required span arrangement and the horizontal
and vertical clearances.
Examples of things to consider while developing alternatives are alternate
routes, accident history, physical impacts,effects on the existing highway
system, economic development impact, and local commitment to
improving local roadways. These alternatives must respond to projected
design year traffic volumes as developed for this scope. Evaluate the
impacts of these alternative concepts and the degree to which they
accomplish the objectives. These concepts will be described
schematically and in narrative,and reviewed by County.
Complete an initial design of the designated alternatives.
Once the alternatives have been selected, general profile and cross
section studies will be developed for critical areas to analyze the
designated alternatives. This information shall be sufficient to determine
general cut and fill limits, right-of-way and easement requirements, and
earthwork and structural requirements. Design parameters such as
design speeds, maximum grades, typical sections, intersection designs,
and pedestrian routing will be determined at the beginning of the study.
The conceptual design for the roadway alignments, detours, and major
structures will be completed sufficiently so that preliminary cost estimates
can be developed and the satisfaction of pertinent design criteria can be
demonstrated. Necessary variances will be identified.
Perform a financial analysis on the selected alternatives.
A construction cost estimate will be developed for the alternatives
selected by the C/PM.

architectural recommendations.
2. When required, collect data on existing structures such as existing
plans, inspection reports, structure rating, foundation information, and
shop drawings.
b.Structure Layout and Type Study ❑
1. Review the structure site data to determine the requirements that will
control the structure size, layout, type, and/or rehabilitation
alternatives. On a continuing basis, provide data and
recommendations to other members of the design team(e.g.,roadway,
hydraulics,survey)to help finalize the structure site data.
2. Determine the structure layout alternatives. Determine the structure
length, width, and span configurations that satisfy all horizontal and
vertical clearance criteria. Working with the roadway designer,
determine the necessary length of walls,and the top and bottom of wall
profiles.
3. Determine the rehabilitation alternatives. Continued use of all or parts
of existing structures shall be considered as applicable. The structural
and functional adequacy of existing structures shall be investigated and
reported. Determine the modifications and rehabilitation necessary to
use all or parts of existing structures and the associated costs.
4. Determine the structure type alternatives. Consider precast and cast-
in-place concrete and steel superstructures and determine the spans
and depths for each. For walls, determine the feasible wall types in
accordance with the CDOT Bridge Design Manual Section 5.
5. Determine the foundation alternatives. Consider piles, drilled shafts,
spread footings, and mechanically stabilized earth foundations based
on geology information from existing structures and early estimates
from the project geologist. To obtain supporting information, initiate the
foundation investigation as early as possible during the preliminary
design phase.
6. Develop the staged construction phasing plan, as necessary for traffic
control and detours, in coordination with the roadway design and traffic
control plan. The impact of staged construction on the structure
alternatives shall be considered and reported.

necessary to evaluate and compare the structure layout, type, and
rehabilitation alternatives.

and comparing the structure alternatives that encompass all aspects of
the project objectives. Elements typically considered include safety,
construction costs, construct ability, life cycle costs (durability),
environmental considerations, aesthetics, in service maintenance and
inspection, and the ability to rehabilitate, widen and replace the new

All invoices shall be submitted by the Consultant to the County for payment
pursuant to the terms of the contract. Upon approval thereof, the County will pay
the appropriate amount of each invoice to the Consultant within 30 days of
receipt of each invoice. Progress payments may be claimed on a monthly basis
as the percentage of the total lump sum fee that represents the ratio of work
performed during the month to the total amount of work.
4. TIME OF PERFORMANCE
The Consultant shall complete the design services defined in the Scope of Work,
Section 7, within 200 calendar days from the date of Authorization to Proceed as
described in Part 1, Section 1.07 of the RFP, exclusive of all days lost for review and
approved by the County. All days lost for review shall be documented by the
Consultant and submitted to the County for consideration.
For each calendar day that the Work is incomplete after the time specified or as
adjusted and approved by County in writing, a sum of $200.00 may be deducted from
moneys due to the Consultant as liquidated damages. This sum is fixed and agreed
upon between the County and Consultant because the actual loss to the County and
to the public caused by delay in completion will be impractical and extremely difficult
to ascertain and determine.
5. TERMINATION OF AGREEMENT
The Agreement may be terminated for cause by the County or Consultant upon
fifteen (15) days written notice. In the event of termination, Consultant shall be paid
for services performed to termination date as mutually determined by County and
Consultant.

by and among the County and Consultant. Any claim by the Consultant for
compensation must be made in writing prior to performance of any changed work or
services.
7. INSURANCE
