Mr. Cooper:

Please find attached, Contract Amendment No. 2 to the M-210 Sanitary Sewer Relocation
Project. This second amendment request specifically addresses the project related costs of
addressing the recent Texas Historic Commission 's (THC) request for an archeological
exploration of a portion of our M-210 Sewer Improvements -Part I Project Area.
During the federal permitting of this construction project, which statutorily requires a project
review by the THC, THC records research by THC Staff indicated an existing prehistoric
archeological site was located at the confluence of a tributary and the old Clear Fork channel west
of our project area near the Fort Worth Zoo parking lot. Becau se of this site, THC Staff viewed
that s ufficient justification exis ted for pursuit of this archeological investigation within our
project area under the National Historic Preservation Act (NHPA) and the Antiquities Code of
Texas (ACT).
Since our project includes constructing a new s anitary sewer main across the City 's Fore st Park
and then siphons under the Clear Fork of the Trinity River, an excavation pit for the river crossing
(tunneled) will be required. This tunnel access will be located g enerally in the vicinity of the
o ri g inal Clear Fork Trinity River which has been identified by the THC as an area of interest, thus
requiring the archeological exploration of the ramped "bore pit".
RJ Group, Inc is propos in g to retain Blanton & Ass oci ates, Inc . (B&A) to provide archeol og ic a l
con s ultin g servi ces in s uppo rt o f the C ity o f Fort W o rth 's Sewe r M a in M-2 10 Sewe r

requ iremen t associated w ith th is p roject. B&A is a certified M/WB E fi rm that is hi g hl y qua lifie d

2. Using up to 2 archeologists, B&A will monitor all excavation activities of the southern,
ramped bore pit which is approximately 60-ft by 15-ft in s ize and extends from the
ground to a depth of 26 feet. These investigations will adhere to THC s urvey standards,
as well as the guidelines of the Council of Texas Archeologists and the Secretary of the
Interior's Standards and Guidelines. The archeologists will be looking for thin lenses of
charcoal/carbonaceous matrix containing prehi storic bones and stone tool sa mples and if
found, these sa mples s hall be collected for radiocarbon dating.
3. Any a rcheological s ite discovered during fieldwork will be recorded on a Texas
Archeological Site Data Form, obtain an official State site number, and document the
horizontal and vertical extent of the identified cultural deposit discovered. Sites will be
evaluated for potential significance and eligibility for inclusion to the NRHP and
recommendation s for further archeological inve stigations. Other than radiocarbon
samples, no other collection of artifacts will be collected at this time. If a significant
discovery is made and THC recommends collection, this will be considered as additional
contract se rvices and require another amendment.
4. Following the completion of excavation monitoring, a draft report describing the results
of the inve stigation will be prepared by B&A and submitted to the THC for review and
comment. Review comments will be addressed and a final report submitted to the THC
per the requirements of the Antiquities Permit. Assuming no s ignificant cultural
resources are di scovered during the excavation monitoring, B&A will work to secure
rapid written approval from THC to release the M-210 project for immediate and
unre stricted construction while the archeological report is drafted , reviewed and finalized.
The field work associated with the effort is anticipated to take up to I week to complete. B&A
labor and expenses for the se rvices noted above will be billed both on a time and material and
unit price basis not to exceed, $17,000.00, without prior written a pproval. Radiological testing
associated with thi s exploration effort will be limited by the s ubcontracting budget established
and billed at a rate of $600 .00 per sa mple collected.
Since this matter has arisen , RJN has been actively engaged in the project planning, coordination
and response to the THC, City of Fort Worth , Tarrant Regional Water District (TRWD) and the
U.S. Army Corps of Engi neers (USACE). RJN has incurred other labor and expenses associated
with this matter, including costs for the preparation of a s ubcontracting agreement with B&A . As
such, RJN is seeki ng funds to recover those costs as well as funding for B&A 's contract
administration in the a m ou nt of a ten (10%) percent s ubcontracting mark-up.
Contract Amendment o . 2 costs are as s hown in the table below:
