Phase II: Design In Phase II, the design of the projects will be developed. In addition, the detailed subsurface investigation of pipeline alignments will be conducted. Activities to be undertaken at each level of completion will be thoroughly identified in the project work plan and schedule, along with key deliverables, meetings and workshops, and coordination assignments as summarized below. Staffing Plan Evaluation Once the scope of work is defined, we can conduct an evaluation of the professional staff assigned to each project to ensure that the right personnel is taking care of our project. Geotechnical 8 Environmental Evaluation A detailed combined geotechnical and environmental survey will be conducted when the final route is established. Specific attention to soil/rock conditions, seasonal groundwater elevations, wetlands and other site features will be investigated. The investigation will focus on possible canal, utility and road crossings, with additional exploratory borings at regular intervals along the pipe alignment. Soil characteristics will be determined to facilitate efficient design of thrust restraint, trench sheaving and dewatering facilities. Surveys and soundings will be conducted for canal crossings for permitting compliance and contractor information. 1 Soff-Dig Utility Verification Where applicable, air/vacuum soil extraction for actual existing public and private utility locations will be conducted. Exact locations of critical utilities will be confirmed by field survey. Construction Plans B. Specifications Plan and profile drawings will be provided for the selected, permitable corridor. Plans will delineate permanent and temporary easements, rights-of-way and applicable property data. Multiple bid packages separating tunnel pipeline work and open-cut pipeline work may be recommended to reduce capital cost and increase number of bidders. Details will be provided for temporary utility service, pipeline appurtenances, bedding, utilities, structures, thrust restraint and connections. A required work sequence with specific requirements will be provided for each bid package. Maintenance of Traffic Plan (MOT) Traffic control plans in accordance with the City, MDPWD, and FDOT standards will be developed where construction activities encroaches on public rights-of-way. Emphasis will be placed on public safety and maintaining the traffic flow status quo. The successful completion of any construction project requires safety. When working on public roadways, safety needs to be extended not only to workers, but also to the general public using these roadways. The only way to extend safety to the workers and the general public is through a Maintenance of Traffic plan. Selecting and implementing the most effective MOT possible will reduce work related accidents. It will also reduce project costs and avoid schedule delays due to accidents. Roadways within the county vary from two-lane two-way to four lanes with a median. MOT plans for each type of troadway is illustrated below. Two-Lane Two-Way, Working Within the Travel Way This MOT plan is very important due to the lack of space and the close proximity of the work area to the general public. The work area will typically take one full lane. Flagmen will direct traffic from both directions through the remaining lane. Since the work zone will constantly ' move, there is no need for concrete barriers. The proper traffic control signs and devises will help all drivers safely maneuver around our work zone. It will also be used, if micro-tunneling is required for complex canal or highway crossings. The working and receiving shafts operate similar to the open-cut work zone. 1 i City of Sunny Isles Beach Continuing Professional Architectural&Engineering Services RFQ 12-04-02 I 28 —
