BACKGROUND:

The Public Utilities Department is continuing a multi-year effort to survey and map the City’s entire storm sewer system.  On August 1, 2023, the Mayor and City Council approved a Professional Services Agreement with TWIG Technologies (formerly Ruettiger, Tonelli & Associates) for Contract 2 in the amount of $220,000.00.  Work included GPS surveying, elevation measurements, and office GIS mapping.  Subsequently, the Council approved Amendment No. 1 on May 7, 2024, in the amount of $186,025.00.

 

City staff requested TWIG Technologies to provide a proposal to continue this storm sewer mapping work to extend the project westward from County Line Road to the western City limits (refer to the attached map exhibit).

 

The Public Service Committee will review this matter.

 

CONCLUSION:

TWIG Technologies has provided a proposal in the amount of $153,140.00 to complete this next phase of storm sewer mapping.

 

Proposals were received for Contract 1 of this program in 2023 and TWIG Technologies was the low proposer.  Amendment No. 2 includes a unit cost increase of 4.0% from the original 2023 contract.

 

Sufficient funds exist utilizing the Water & Sewer Operating Fund / Engineering Administration / Professional Services (Org 50080013, Object 523300, $153,140.00).

 

RECOMMENDATION:

recommendation

Based on the above, it is recommended that the Mayor and City Council approve Amendment No. 2 to the Professional Services Agreement for Contract 2 of the Storm Sewer GIS Mapping Project, in the amount of $153,140.00, on behalf of TWIG Technologies.
