Resolution to Approve Amendment No. 3 the Professional Services Agreement with Orchard, Hiltz & McCliment, Inc. ($119,000.00) for the West Park Storm System Modifications Project
Memorandum
This is to recommend approval of the attached resolution to amend the Professional Services Agreement (PSA) with Orchard, Hiltz & McCliment, Inc. (OHM) for additional engineering design and construction staking and inspection services to be used on the West Park Storm System Modifications Project.
The original PSA with OHM, approved by Council on June 4, 2007, was to provide engineering support to the Project Management Services Unit during peak demand periods. The original PSA with OHM was established for an amount of $85,000.00 and authorized the City Administrator to approve $35,000.00 for additional engineering services (amendment No. 1).
In December 15, 2008 the City Council approved amendment No. 2 for $85,000.00 for additional general engineering services. The total PSA with OHM as amended to date stands at $205,000.00. This remainder of this PSA was used to provide engineering services to the City for the West Park Storm System Modifications Project in order to review the design of the stormwater system and investigate the cause of the failures of the stormwater swirl concentrator units installed in 2010. OHM provided the City with a report dated August 30, 2011 outlining their recommendations.
In order to get the swirl concentrator units back on-line in the spring of 2012, the City needs to extend the PSA with OHM to include engineering design services to implement the recommendations from their report, and to design replacement structures for the failed swirl concentrator units.
Amendment No. 3 will include additional stormwater modeling, engineering, and survey work that was performed in order to complete the investigation of the existing system and failure of the swirl concentrator units ($25,000.00) for the West Park Project. Amendment No. 3 will also ...
