Contract No. 8
Project No. 00021
CPBY Project No. CFW0437
Dear Mr. Henry:
The enclosed proposed Amendment No. 2 for the Capital Improvements Program for the City of
Fort Worth Engineering Department adds additional task items required to design changes to
the sanitary sewer lines in the Langston Street area.
BASIC SERVICES TASK ITEMS
Proposed design changes make the task descriptions included in Amendment No. 1 obsolete,-
therefore, the basic services task items included herein supersede the task items included in
Amendment No. 1. Compensation for task items in this amendment include the fee already
approved in Amendment No. 1 plus the additional fee contained herein_
Project Description
As part of the City's continuing effort to relocate sewer lines currently constructed between
residential buildings, the City has requested that CPBY abandon sewer L-4509 from Station
0+00 to Station 1+48. The City has also determined that age, line breaks, and clogging issues in
M-191 between Station 99+58 to approximately Station 109+22 has resulted in poor service line
draining for homes on the east side of Langston. The City proposes relocating M-191 onto
Langston as generally described in the following task items. Relocating M-191 into Langston
Street also requires rerouting all service lines for homes on the east side of Langston Street.
SCOPE OF SERVICES
Project Tasks
As part of the professional services required to complete this project, the Engineer will perform
the following tasks:
