1. BACKGROUND:
A. Need. This legislation authorizes the Director of Public Utilities to modify the professional engineering services agreement with CH2M Hill, Inc., for the Southerly Wastewater Treatment Plant Sludge Thickening Improvements and Additional Renovations Project. The modification amount requested under this ordinance is $330,423.00. The contract total including this modification is $10,660,620.00. The proposed contract modification provides funding for additional Detailed Design Services that became necessary in the course of the design development for Contract J216. It is not deemed either feasible or reasonable to suspend work with the entity currently under contract and undertake continuation of these services with another provider. The cost of the modification is a continuation of the vendor's current pricing structure, as verified by City staff. The Division has determined that these services cannot be performed by City personnel at this time.
This is a contract for professional engineering design services and services during construction (Design Professional, or "DP" services). This contract implements improvements for one of the wastewater plants construction projects in the City's Wet Weather Management Plan (WWMP) program.
This is the third phase of a multi-phase project and part of it is included under J216 Contract for the Jackson Pike Wastewater Treatment Plant (JPWWTP) Polymer System Renovation project. The existing Jackson Pike polymer systems are deficient and in need of replacement. This specialized work is being performed by this Design Professional because the systems at Southerly, which were designed by the same DP, are reliable and will be mirrored at Jackson Pike. The preliminary design has been completed.
The actual emplacement of this work will be carried under the construction contract. This enginerring contract provides detailed design and bidding assistance, along with construction-phas...
