o Evaluation Committee members then discussed their initial scoring for the Technical <br />and Managerial Proposal Criterion based on a total of 50 points. Following <br />discussion, Evaluation Committee members developed their final scoring that averaged <br />as follows: <br />Technical and Managerial Proposal Criterion Scoring <br />Frank Coluccio Construction Company <br />44.4 out of 50 points <br />• Overall technical approach and design <br />concept to install new pipeline under the <br />Pilchuck River: <br />Proposed concept includes constructing <br />trapezoidal plastic Tined temporary <br />diversion channel to the east with <br />diversion dam further upstream. Trench <br />box and sheeting proposed for pipeline <br />installation. <br />• Approach to river diversion and surface <br />and groundwater dewatering: <br />Temporary diversion provides for <br />anticipated river normal flow and potential <br />rain occurrence. Providing up to eighteen <br />36" diameter wells and up to four 120' <br />deep pressure relief wells. <br />• Utilization of existing City owned materials <br />in final design: <br />Proposed using all of City owned materials <br />and adding an additional 10' of pipeline to <br />mitigate for possible future easterly river <br />migration. <br />• Construction approach, including permit <br />compliance approach: <br />Proposing 4 stages. Starting with work <br />above OHWL so temporary diversion <br />channel is in place before July 1 when <br />permits allow in -water work to begin. <br />• Ability to meet time requirements as <br />evidenced by proposed schedule and <br />schedule management approach: <br />Schedule has built in float should in -water <br />work exceed planned. <br />• Ability to meet budget requirements as <br />evidenced by proposed cost management <br />approach: <br />Proposing monthly monitoring of design <br />and construction cost and progress. <br />• Recent, current, and projected workloads: <br />Current and future workloads submitted <br />indicate capacity to perform this project. <br />• Office location, <br />Seattle, WA <br />IMCO Construction <br />48 out of 50 points <br />• <br />Overall technical approach and design <br />concept to install new pipeline under the <br />Pilchuck River: <br />Proposed concept includes constructing <br />rectangular sheet pile temporary diversion <br />channel to the east and diversion dam <br />closer to the actual crossing. Sheetpile <br />shoring proposed for trench shoring for <br />pipeline installation. <br />Approach to river diversion and surface <br />and groundwater dewatering: <br />Temporary diversion provides for <br />anticipated river normal flow and potential <br />rain occurrence. Proposing 26 dewatering <br />wells in addition to using sheet piling and <br />concrete tremie construction. <br />Utilization of existing City owned materials <br />in final design: <br />Proposed using all of City owned <br />materials. <br />Construction approach, including permit <br />compliance approach: <br />Proposing 4 stages. Starting with work <br />above OHWL so temporary diversion <br />channel is in place before July 1 when <br />permits allow in -water work to begin. <br />Ability to meet time requirements as <br />evidenced by proposed schedule and <br />schedule management approach: <br />Schedule has potential for accelerating <br />based on final permit approvals. In -water <br />work consists of using similar sheet pile <br />construction as work above the OHWL <br />thus allowing team to fine tune process <br />before starting in -water work. <br />Ability to meet budget requirements as <br />evidenced by proposed cost management <br />approach: <br />Proposing open book, transparent cost <br />accounting. <br />Recent, current, and projected workloads: <br />Current and future workloads submitted <br />indicate capacity to perform this project. <br />Office location <br />Ferndale, WA <br />Page 12 <br />119 <br />
