Executive Summary: |
As part of the Integrated 2012 Water Utilities Plan Technical Memorandum No. 10 and Appendix I, the Kaw Water Treatment Plant (WTP) was evaluated for structural, electrical and process deficiencies. The report identified, and recommended repair on numerous areas of cracked and deteriorated concrete in the plant’s carbon contact basin, secondary basins, as well as the concrete walkways, and weir troughs.
Walter P Moore has completed a structural condition assessment of six basins at the Kaw Water Treatment Plant. The condition assessment recommended the following repairs: repairing concrete spalls and delamination on basin walls and slabs, crack injection, and concrete coating.
Staff have negotiated Supplemental Agreement No. 1 to the existing Engineering Services Agreement with Walter P Moore for additional Design Phase Engineering Services in the amount $39,300.00. The scope of this supplemental agreement includes construction documents for repairs on the presedimentation basin, primary settling basins, and secondary settling basins.
The proposed scope of services and fee for the design of the construction documents for the Kaw Water Treatment Plant Structural Improvements Project UT1503 in the amount of $39,300 is commensurate and appropriate for the project. The fee includes basic A/E services as well as non-basic A/E services related to the advertising and bidding of the project.
The basic A/E design phase cost ($35,700.00) is 5.5% of the estimated $650,000 construction cost, which is below the recommended amount of 8.8% per the design fee guideline adopted by the City of Lawrence on January 11, 2011. Additional non-basic A/E services related to bidding phase services ($3,600) for the project as a percentage of the estimated construction cost of 0.6% are commensurate and appropriate for the project based on historical project costs. |
