approach for requesting, developing, and completing task order assignments. This process provides the City with teams available for multiple tasks off the on -call contract and a formal approach to respond to each task. Below, we summarize our proposed approach for completing the task orders. ■ Step 1— Initial Meeting with City Project Manager and Task Managers: A meeting between the City's Project Manager and the Ardurra task manager to be assigned to the work will be set up. Ardurra's manager will discuss the request with the City's Project Manager and discuss your goals and expectations, key project issues, appropriate personnel from our team to be assigned, services needed, schedule, approximate budget available, and assumptions for completing the work order. ■ Step 2 — Develop Scope of Work and Team: Ardurra's task manager will then coordinate with key people from our team to prepare and submit a proposal for completing the work. Each team member will submit his or her scope to the task manager, who will then combine the individual scope into an overall scope and proposal for review by City. This procedure has worked successfully on our current and past on -call contracts. ■ Step 3 — Notice to Proceed: Once the City reviews, negotiates, and executes the task order, it will provide Ardurra a Notice to Proceed. If applicable, Ardurra will issue a subsequent notice to proceed to our subconsultant(s). ■ Step 4—Monthly Coordination/Progress Meetings: We will hold meetings at a frequency to keep City staff apprised of the progress of the work. We will develop and maintain schedules to identify allowable work windows for completing project tasks and to keep the City's Project Manager aware of the project progress. Critical Technical Elements Our design team's technical approach involves considering the following critical technical elements, depending on the type of project. Pipeline Design Technical Approach • System and pump hydraulics/surge effects • Alignment selection and easement acquisition • Pipeline separation requirements • Utility crossings, summarized on plan and profile sheets • Corrosion issues, specialty coatings and materials • Geotechnical/foundation conditions Environmental constraints • Operation and maintenance issues • Contracting strategies, scheduling, and budget control • Traffic control • Construction impacts (i.e., noise, dust) • Compliance with regulatory requirements • Where trenchless pipe construction is utilized, classification by OSHA • Mining and tunnel unit (>30-inch diameter) • Preparation of SWPPPs and other compliance requirements for the State's General Construction Permit and County • For pipes in the public right-of-way, compliance with local agency municipal codes and ordinances regarding utility installations, traffic control, street resurfacing, and potholing activities Typically, the most challenging aspect of underground pipeline design and construction is definition of existing facilities or utilities, particularly when there is sparse or no information. Czar loam utilizes a methodical and detailed utility research and plotting procedure that provides for a high level of confidence with respect to the locations of subsurface utilities. Our procedure is generally outlined as follows: ✓ Upon authorization by the City, contact USA Dig -Alert to obtain a pre -planning request, which provides a listing of existing utility agencies in the project areas. Establish one point of contact at Ardurra to serve as project utility coordinator and be responsible for tracking and documenting all utility requests and responses. ✓ From the USA Dig -Alert pre -planning list, contact all utility agencies in or around the proposed work area to establish contact information and lines of communication. ✓ Send to each utility agency a Utility Notice of Planned Improvements to formally request their system maps and record drawings. ✓ The project utility coordinator will review information received for responsiveness and completeness, and will follow up with phone calls or in -person visits to agencies as necessary. ✓ Plot the utilities, along with proposed horizontal and vertical alignments (depending on submittal milestone). Send to each agency a set of plans for conflict check at each submittal milestone. Incorporate comments as necessary. ✓ Once the utility base map is established, perform QA/ QC including a field review to determine if all the plotted information is accurate with field conditions. ✓ If necessary, perform potholing to obtain actual field data for key utility crossings or parallel utilities of interest. ✓ Document and track the process at each step. Agencies are sent plans at each milestone regardless of whether or not there are conflicts, or conflicts have been resolved, due to potential changes in alignment, existing utilities, or agency review personnel. ✓ All utility information is plotted in the plan and profile sheets and summarized in a crossing table. Our utility research procedure has resulted in an excellent track record of avoiding conflicts during pipeline construction.
