BACKGROUND:
The scope for this change in services with Halff Associates, Inc. was negotiated and is being submitted for Council approval for a not to exceed amount of $294,170.00. This Change In Service # 4 increases the contract to finalize the design plans and provide engineering services during construction.
In late 2014 the City Council approved the cancellation of $99,000 in CAMPO funding and delayed the project due to construction conflicts with the N. LBJ and to allow more time to address design issues. Over the last year staff has surveyed residents about the project scope, performed additional drainage investigations, continued to work with TXDOT on the ROW transfer and have identified additional beautification aspects to add to the project.
This change in service will include:
• Drainage
o Sara Street Drainage included
o Revise calculations based upon revised cross section.
• Water
o 8” will be increased to a 12”
o Add 6” to 8” replacement on Sara street to accommodate drainage improvements
o Location will be moved into the street to allow for smoother construction
• Wastewater
o Add replacement from Coers Street due to deteriorating condition
o Add replacement on Sara street to accommodate drainage revision and deteriorating condition
• Sidewalk
o Old RR 12 between Craddock and Hughson (Retreat Side) - Increase sidewalk size from 6’ to 10’ and relocate into sidewalk easement
• Beautification
o Add additional landscaping and irrigation to the plans
o Add decorative crosswalk to the project; where feasible
o Replace concrete rip rap with decorative retaining walls; where feasible
• Driveways
o Investigate alternative design options for addressing steep driveways
• Traffic Calming
o Provide documentation required to temporarily reduce the speed during construction from 40 MPH to 30 MPH.
o Add traffic feed-back signs to the project.
• TCEQ
o Additional support needed for coordination with TCEQ and receiving approval for water quality features to be installed
The current cost estimate of $3.6 Million is expected to increase to approximately $4.5-5.0 Million with these revisions. Construction is expected to start in the winter of 2018.
Staff recommends approval of this change in service.
