For Landscape Architecture and Civil Engineering Services
For additional services related to the construction administration and inspection of the greenway trail at the /
Twin Creeks District Park located in Carrboro, North Carolina. ~~
Description
This proposal is for additional Civil Engineering services related to the construction administration and
inspection of the greenway trail at the Twin Creeks District Park. During the design phase of the project,
Orange County was able to obtain ARRA funding for a portion of the trail construction. A requirement of
receiving ARRA funding for the project is that full time inspection services be provided, and that
construction phase services be provided as if the project were a NCDOT project. The ARRA funding also
requires additional state and federal reporting requirements be met during construction. The construction
phase services required by ARRA exceed the scope of construction phase services in the design contract for
the greenway trail.
This proposal does not include NCDOT certified testing of construction materials. Orange County will be
responsible for contracting with a certified testing firm to provide construction material testing as required
by NCDOT requirements. The construction material testing required includes, but is not limited to, soil
density tests, stone density test, concrete sampling and tests.
ADDITIONAL SCOPE OF BASIC SERVICES:
1 Construction Phase Services
l .Ol Provide a resident project representative who will be at the site at times construction crews are
working who will be responsible for preparing and maintaining all written documentation
necessary to satisfy NCDOT to comply with A. R. R.A. funding procedures for the Twin Creeks
Greenway Project.
1.02 Prepare daily reports, journals and logs of all construction activities and construction work
performed in accordance with NCDOT guidelines.
1.03 Document the receipt of all materials, equipment and machinery delivered to the site.
l .04 Obtain receipts and tickets of materials delivered to the site. Document the day and time of the

associated costs as it relates to bid items and the Contract.
1.06 Validate all monthly pay estimates for review by the Engineer that will be forwarded to the
Orange County for payment.
l .07 Coordinate the scheduling of all NCDOT certified inspectors at times that materials (stone
base, concrete etc...) are being placed by the Contractor.
l .08 Coordinate the scheduling of all compliant testing by a NCDOT certified materials testing firm
for construction of the trail (NCDOT certified material testing firm to be provided by Orange
County).
1.09 Provide daily inspection oversite.
1.10 Bring to the attention of the Engineer unforeseen problems so they may be corrected in a
timely manner so as not to hinder or slow construction. Document all unforeseen problems
and associated costs for review by NCDOT.
1.11 Attend periodic construction meetings as stipulated by the Engineer.
1.12 Review project submittals and Change Orders.
1.13 Perform substantial completion and final completion inspections.
All other provisions of the existing Contract between Orange County and Coulter Jewell Thames will
remain in effect.
COMPENSATION:
The exact amount of construction phase services to be provided to Orange County will vary depending on
the actual construction duration and days worked by the Contractor. Therefore, Coulter Jewell Thames, PA
proposes to provide the construction phase services on an hourly basis, at the rates listed below, which will
be invoices to the County monthly. The hourly rates listed include our transportation cost to the site and at
the site.
The estimated dollar amount of construction phase services to be provided by Coulter Jewell Thames, PA
has been calculated based on a construction duration of 28 weeks, with the resident project representative
and project manager staffing the project 40 hours per week and 10 hours per week, respectively. Monthly
invoices will update both Orange County and Coulter Jewell Thames, PA on the construction phase
services budget.

The design contract for this project included a fee of $25,000.00 for construction phase services. The
construction phase services portion of the previous contract will be nullified by the approval of this
Amendment. The Construction Administration and Inspection Budget above reflects a total increase in
construction phase services of $81,400.00.
