Item Summary:
The Creek Bend Boulevard Extension project extends Creek Bend Boulevard from Creek Bend Circle to Wyoming Springs Drive
and will provide a much needed creek crossing west of IH35. The proposed project was first approved by the City in 1999 as part
of the Transportation Master Plan and was approved for funding in the 2001 bond election. The project has languished due to
numerous obstacles and delays. The original engineering contract with Atkins North America, Inc. in the amount of $179,898.43
provided for a 30% design schematic.
Supplemental Contract No. 1 consists of preparation of final (100%) Plans, Specifications, and Estimates (PS&E), bidding phase
services, and construction phase services. Final PS&E will be developed from the approved 30% design schematic and will
include supplemental design survey, right-of-way acquisition surveying services, environmental studies, roadway design, bridge
design, water quality design, water line design, pedestrian/sidewalk improvements and utility relocations. The cost of
Supplemental Contract No. 1 was $805,808.42. Supplemental Contract No. 2, at a cost of $21,570.57, amends the agreement to
include additional services to study and define limits of the void encountered during geotechnical drilling.
Supplemental Contract No. 3 provides for a geophysical study to assess the presence of voids and related features along the
proposed Creek Bend Boulevard alignment from Station 23+25 to Station 27+25 at a cost of $49,900. The total cost of the
construction contract would be $1,057,177.42.

PROJECT DESCRIPTION
This Supplemental Contract consists of a geophysical study being done in order to assess the
presence of voids and related features along the proposed Creek Bend Blvd alignment from
station 23+25 to station 27+25.
TASK 1: SURVEYING — Not Included with this Supplemental
TASK 2: ROUTE STUDY — Not Licluded with this Supplemental
TASK 3: ENVIRONMENTAL STUDIES
1. Round Rock Geophysics, LLC (RRGeo) will conduct a geophysical study within the
proposed Creek Bend Blvd right-of-way from station 23+25 to station 27+25. The
objective of this study is to assess the presence of voids and related features via a
noninvasive technique that retains the biological integrity of the subsurface voids. The
proposed geophysical method is called seismic refraction tomography, which uses
compressional wave (P-wave) and shear wave (S -wave) travel time measurements,
thereby creating 2D and 3D images of the subsurface velocity structure.
Data will be collected along seven parallel lines oriented along the proposed alignment of
Creek Bend Blvd and spaced approximately 20 feet apart. Each line will have a survey
length of approximately 400 feet. There will be a total of 7 shot points per line and a
geophone spacing of 5 -foot. A land streamer with 8 -Hz vertical geophones will be used
to collect data. A minimum depth of exploration of 25-35 feet is planned.
The field data will be downloaded and processed using industry standard software
packages. The RREG report will include:
• Description of the data acquisition procedures
• Equipments and software used for data collection
• Data quality and site condition
• Data processing procedures
• Results of data processing (2D and 3D displays)
• Interpretation of the final results in terms of characterizing the void and associated
features,
• Conclusion and recommendation
• Final site visit would be planned to mark the horizontal dimensions of the void on the
surface.
