Description
The construction phase services for the Twin Creeks greenway trail are outlined in a Letter of Amendment
to an Existing Contract provided by Coulter Jewell Thames PA dated January 7, 2010, and executed by
Orange County on March 11, 2010. In the Letter of Amendment, a budget for construction phase services
was developed based on a construction duration of 28 weeks. The total construction phase services budget
was $106,400.00. Under the terms of the letter, Coulter Jewell Thames, PA has invoiced monthly against
this budget for the hours spent on the project.
A Notice to Proceed for the project was issued on February 17, 2010, with construction beginning on
February 18, 2010. A 28 week construction duration beginning on February 18th would have concluded on
September 2, 2010.
Coulter Jewell Thames has invoiced Orange County a total of $86,675.00 for services provided though
October 31, 2010. By invoicing Orange County for the actual hours of construction phase services
provided., we have been able to work beyond the originally estimated construction period and remain within
construction phase services budget. However, based on the current schedule for completion of the project,
we do expect to exceed our construction phase services budget prior to completion of the project.
We estimate that we will be required to provide the equivalent of 12 weeks of construction phase services
for the project for the period from November 1, 2010, through completion of the project. Each week of
construction phase services would include 40 hours for the resident project representative and 10 hours for
project manager.
Due to the extended construction period for the project, Coulter Jewell Thames, PA is requesting that our
construction phase service. budget be increased by $25,875.00 to a total of $132,275.00. Calculations of the
estimated services remaining to be provided and the amount remaining in the budget are provided on the
next page.

COMPENSATION:
As per the existing Agreement, 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. The
addition of the $25,875.00 to the Contract Amount provides a budget for services totaling $132,275.00.
All other terms of the existing Agreement shall remain in effect.
