Text of Legislative File CM -2019-0074
The purpose of the proposed RM 620 Safety Improvements project from Deep Wood Drive to
1H 35 is to improve safety and enhance mobility in the project area. The project includes a
bridge to carry RM 620 traffic over the Union Pacific Railroad (UPRR) and Chisholm Trail
Road. In order to maintain access to businesses and residences in the vicinity of the proposed
bridge, at -grade local access roads will be constructed between Lake Creek Drive and
Chisholm Trail Road. A second bridge is proposed to carry RM 620 traffic over Lake Creek
Drive. The project area is within the Edwards Aquifer Recharge Zone.
On June 27, 2013, an engineering services contract for $955,823.00 with Halff Associates, Inc.
was approved by the City Council. Services covered in this contract were geometric schematic
and 30% Plans, Specifications, and Estimate (PS&E).
Supplemental Agreement No. 1, approved May 8, 2014, provided for professional services to
develop 60% PS&E in accordance with the approved preliminary design schematic and 30%
PS&E developed for this project. The cost of these services was $698,445.00 and brought the
total contract amount with HalffAssociates, Inc. to $1,654,268.00.
Supplemental Agreement No. 2, approved May 14, 2015, provided for engineering, surveying,
and other professional services to develop and finalize 100% PS&E, utility coordination and
water/wastewater relocation design, water quality, environmental site remediation, public
involvement, and right-of-way (ROW) and easement parcels for this project. The work
performed under this supplemental delivered the final design in accordance with the approved
CityofRoundRack page 7 Printed on-Wiaof9
Agenda Item SummarY Continued ICM -2019.0074)
preliminary design schematic, 30% and 60% PS&E developed for this project and additionally
rendered the project "shovel ready". The cost of these services was $682,232.00 and brought
the total contract amount with Halff Associates, Inc. to $2,336,500.00.
TOOT recently programmed and funded this project for FY2019 letting. Supplemental
Agreement No. 3 provides additional engineering services and utility coordination through
relocation, permits, pre -letting support, and other items required for TOOT to approve and let
the project in 2019. The cost of these services is $118,265.00 and brings the total contract
amount with Halff Associates, Inc. to $2,454,765.00.
This Supplemental Agreement #4 has become necessary for the following items. This office
met with Round Rock High School Administration and as a result of that meeting a traffic study
to research how to mitigate traffic during construction was agreed to be developed. This SWA
also includes the PS&E work to let a section of storm sewer line on Chisholm Trail prior to the
RM 620 project being let by TxDOT. This is to provide a connection for the storm sewer system
that will be advanced from the RM 620 project. The initial plan was to let in a Parks project but
they have delayed their project. The cost of this SWA is $49,940.00.
Staff recommends approval.
Cost: $49,940.00
