PROBLEM/ISSUE STATEMENT
The City of Billings and Kadrmas, Lee & Jackson (KLJ) entered into a Professional Services Contract on June 23, 2014. W.O. 14-09 involves constructing a new water tank to serve the Briarwood area. Amendment 1 was approved October 21, 2014, and provided for additional geotechnical field work and evaluation of the poor soil characteristics in the Briarwood area.
From the results of this additional geotech work, it was determined that a drilled-pier foundation system was needed to adequately support the tank. The foundation was designed accordingly, but the construction of this complex foundation will require much more inspection (by qualified personnel) than what was originally anticipated for the project. In addition, due to the City's stringent electrical and instrumentation & control (IC) requirements, additional construction oversight will be needed. Amendment 2 will provide the additional inspection and construction administration for these issues.
For Quality Assurance (QA) testing, the City typically would contract separately with an approved testing firm. However, because of the close coordination needed between the design and testing personnel on this project, KLJ is teaming directly with SK Geotechnical, one of the City's approved testing firms, so Amendment 2 will cover the additional QA services that are not included in the original scope.
More specific details of the services provided by Amendment 2 can be found in the attached copy of the amendment.

ALTERNATIVES ANALYZED
The Council may:
- Approve Amendment No. 2 to the Professional Services Agreement with Kadrmas, Lee & Jackson; or
- Not approve Amendment No. 2 to the Professional Services Agreement and potentially inhibit KLJ's ability to provide all the construction engineering services deemed necessary for the complex site conditions.
