Smith, Assistant City Manager for Public Services Keith D. Alexander, Director of Water Management �a � � SUBJECT: Water System Improvements Phase II - City Project W06-03 Construction Bid Award SUMMARY RECOMMENDATION: Council adopt the attached Resolution awarding a construction contract to Christy-Foltz, Inc. at a lump sum cost of$1,796,384. BACKGROUND: This project was first presented to Council in August 2006. It is the second and final phase of ' Water System Security and South Water Treatment Plant SCADA Improvements. Only one I� construction bid was received last year for this phase. Since it was well above the budgetted I amount, the bid was rejected. The project scope was slightly scaled back, two bid alternatives were developed and the budget appropriation was increased so that the project could be rebid this year. The revised project plans and specifications were prepared by Strand Associates (our engineering consultant for this project) and advertised on September 3. Bids were opened on October 24 with the results shown on the attached bid tab summary. There are 3 components of the summary that require further explanation: Lump Sum Bid - is the vast majority of the project work which includes the replacement of a lime slaker, powder activated carbon feed systems, polymer and polyphosphate mixing and feed systems, numerous SCADA upgrades, remote site radio systems and select instrumentation. The lump sum bid is under budget and recommended for award by Council. Bid Alternative No. 1 - is for the removal of the potassium permanganate feed system that is no longer in use. Since this alternative can be accomplished under budget it is recommended for award by Council.
