City Council Regular Meeting

Meeting Date:

07/27/2021

BACKGROUND

City Staff has identified some streets in the City where it is desirable to have some geotechnical investigations done to get a better understanding of the existing street section and underlying soil conditions. This information will be used to help plan for future street projects. The list of streets is as follows:

Boening Drive
Doerr Lane
Lookout Road (west of Doerr Lane)
Lower Seguin Road (west of FM 1518)
Old Wiederstein Road
Schertz Parkway (north of Woodland Oaks Drive)

Other than Doerr Lane, the streets identified represent projects on the 5-year SPAM plan or projects listed in the Capital Recovery (Traffic Impact Fee) CIP list. Staff has noticed more rapid deterioration occurring in Doerr Lane and as a result, has added that street to the list to help determine why the street that is occurring. When the cost estimates were prepared for most of the projects listed in the Capital Recovery Project and 5-yr SPAM CIP, certain assumptions were made based on anecdotal information. Specifically, the goal was to be able to “salvage” the existing street section and use it as a “base” for the improved street section. The geotechnical investigation will confirm this assumption or provide clear direction on what needs to be constructed for each roadway. For example, the geotechnical investigation proposed for Schertz Parkway will confirm if we can do the originally planned 2” mill and overlay identified in the 5-yr SPAM CIP or if something similar to what was done last summer on Schertz Parkway south of Live Oak (4” mill and overlay) is required.

Terracon is one of the City's On-Call Geotehnical Engineering firms that was selected and awarded an on-call contract based on an RFQ and are able to provide these types of professional services. Staff negotiated a scope and fee proposal to provide the desired geotechnical investigations and the creation of a report to identify the most appropriate path forward on each of the listed streets.

GOAL

To obtain authorization from City Council to execute a Task Order Agreement with Terracon Consultants, Inc. to provide professional engineering-related services for $65,845, and to authorize a not to exceed amount of $70,000 for the Schertz SPAM Geotechnical Services Project.

COMMUNITY BENEFIT

Completing the geotechnical investigations will provide for a better understanding of the existing street sections. The additional information will allow for the project estimated costs to be revised, if necessary, and improve planning efforts for the projects.

SUMMARY OF RECOMMENDED ACTION

Approval of Resolution 21-R-73 authorizing a Professional Services Contract with Terracon Consultants Inc. for a not to exceed amount of $60,000 for the Schertz SPAM Geotechnical Services Project.

FISCAL IMPACT

Funding for the Geotechnical Evaluation project is available in the excess general fund reserves already earmarked for SPAM projects.

RECOMMENDATION

Staff recommends approval of Resolution 21-R-73, a Task Order Agreement with Terracon Consultants Inc. for $65,845 and a not to exceed amount of $70,000 for the Schertz SPAM Geotechnical Services project.
