Section C. Understanding of Need PROJECT UNDERSTANDING Based on our review of the project request for proposal and the associated plans and specifications, we understand that the San Lorenzo Sewage Lift Station Project will consist of construction of the following: • Lift station —below ground dry and wet wells • Aboveground CMU block building • Three (3)15 hp dry pit sewage pumps • Piping, fittings, valves, flow meter, in -line grinders, rail and hoist system • HVAC, ventilation and ducting • Electrical and instrumentation • Site grading and improvements • 560 (LF) of 15" gravity sewer pipe 190 (LF) of 12" gravity sewer pipe + 545 (LF) of 10" force main • Sewer manholes and appurtenances • Abandonment of existing Segerstrom Lift Station The anticipated start of construction is late fall 2018 with a duration of 14 months. The estimated cost of construction is $6 million. PROJECT APPROACH The Butler Team will use a project control system consisting of the following four elements that will provide quality assurance/quality control procedures and guidelines in the execution of the San Lorenzo Sewage Lift Station Project. a. e m • m The CM Team's ability to monitor and manage the Contractor's performance will be critical to minimizing problems during construction and potential claims. Contractor schedule requirements will include substantial completion deadlines and interim and final completion dates. The construction progress will be evaluated based on approved, resource -loaded CPM schedules (Primavera P6). The Contractorwill be required to submit CPM schedules to the City for acceptance in addition to timely, detailed status Information as the work progresses. The Butler Team will evaluate the Contractor's actual performance by comparing actual qualities completed versus planned. Anticipated work to be accomplished will be reviewed based on a two -week "look ahead" schedule updated weekly by the Contractor. Available Information must be evaluated for schedule exceptions, available contractual options, and corrective actions required by the Contractor. The CM Team will address schedule variances with the Contractor at weekly progress meetings. The CM Team will evaluate each variance, its cause and possible corrective actions, and require the Contractor to provide an action plan to correct unsatisfactory variances. If a satisfactory resolution is not achieved and the Contractor falls significantly behind schedule, the CM Team will require the Contractor to submit a recovery plan. The plan should address mitigation efforts such as additional crews, additional shifts, or developing work -around schedules that move the delayed activity off the critical path so that its completion will not affect critical milestones. eI 11111111111111111,11111M The Butler Team will develop a QA/QC Plan for the San Lorenzo Sewage Lift Station Project. The plan will reflect a set of objectives defined by City staff and assigned CM and field Inspection personnel. The QAIQC Plan will be organized accordingly: • Organization and Responsibility; • Execution and Schedule; • Procedural Requirements; • Requirements for Consultants; and 0 Project Quality Management Audits
