Dan,
I have reviewed your contract amendment #2. Please send us additional documentation & detail on the additional 172
hours. Some of the items listed we would expect to be included within the original contract. We want to treat you fairly and
pay for additional services, however we can not approve this request as is.
Thank You,
George Marshall, PE

Contract Amendment #2
Dear Mr. Marshall:
We are asking the City of Coppell for amendment to our contract for the above referenced project. This
amendment No. 2 is for additional engineering services for drainage design and analysis that was not
included in the original contract. The original scope of the project had no provision for engineering
services for storm sewer design or analysis at the eastern side of the project where the existing storm sewer
outfalls to a pond before entering into Denton Creek. By recommendation of the City we excluded the cost
of this design because that area had recent improvements to the storm sewer system through private
development. After the contract was awarded further analysis was completed and concluded that the
system was not adequate to handle the 100 year rainfall event.
The following is a summary of work associated with the drainage analysis and design showing the
approximate additional hours utilized for this design:
Existing Site Analysis hours
-Site visits 10
-Review of existing record drawings 20
-Meetings/communication with City Staff 10
-Runoff computations/Drainage area maps 30
Engineering Design
-Horizontal alignment alternatives 35
-Profiles for alignment alternatives 35
-Preparation of Plans/Specification 30
-Cost estimates 2
Total Hours: 172
Attachment 1 is our effective hourly rates for engineering services. The additional time outlined above only
considers time utilized by the Associate and Project Manager for this particular project. I have based the
rate on my rate of $140.00 per hour. Therefore, 172 hours at $140.00 per hour equates to $24,080.00. If
this is acceptable to you please let me know or if you need this amendment to be in a different format.
If you have any questions regarding this letter or work performed to date, please call.
