SR-55/Ritchey Water Improvement Project Construction Management & Inspection Services OCTA is procuring easements on both sides of the SR-55 with Western Exterminator and RICOH. The RFP identified a waiting period until approximately July 2022 before work in this area can begin. This affects the start of the two casing crossings. Coordinating with OCTA to determine the earliest start date and advance notification to City's contractor is important to the critical path. OCTA is coordinating with Caltrans for the SR-55 Widening Project; with OCTA procuring the CM and Caltrans procuring the construction contractor. The SR-55 project is to be completed between the two phases of work on the City's SA-7 Pressure Reducing Facility Per the RFP, we are to assume a 12-month construction period. It is important to closely coordinate with OCTA and their CM team to ensure the Caltrans contractor is aware when the area will be ready for them to begin relocation of the 8' x 4' RCB and for us to be aware, well in advance, of when the Caltrans contractor will have completed their work for efficient transitions and schedule maintenance. Site walk-throughs with OCTA/Caltrans are imperative before turning over the area and when receiving it back. Photos and videos will be taken in both instances to document the condition. Both events would be required to be included on the City contractor's CPM schedule. rxe Ritchey Street Water Main: The line in Ritchey St. is a large water main which provides water service and FDC water to businesses in the area, to fire hydrants, and provides water service to the east side of the SR-55 via the existing SA-7 Facility/SR-55 casings. The work activities, testing plans, and notifications to the City (SA-7 Facility) and local businesses are critical to good relationships with 3rd parties and completing a smooth operation. Detailed work activities and notifications are all to be shown on the contractor's CPM schedule. Personal contact with each business by the CM team is imperative. City personnel are required by the Specifications to turn on or off any valves as part of the shutdown. This will be adhered to and is part of the shutdown workplan and notifications. SA-7 Facility: Critical to the City of Santa Ana's water operations and per City requirements, this facility can only be shut down for 7 consecutive calendar days. The CPM schedule would include pipe/electrical installation, testing/commissioning, and would be monitored closely to ensure no time slippage. To ensure the shutdown is completed within the required 7-day period, the contractor would be required to submit a Testing/Commissioning Procedures submittal and a 7-Day Shutdown Activity submittal. off"VE • • • As noted in the discussion regarding concrete encasement for pipe angle points, potholing of the known existing crossing utilities is required first thing on the project before any other construction. In addition to potholing the known utilities, the CM team will ensure the contractor contacts DigAlert to mark utilities in the entire footprint of the Project to ensure the designer did not miss any or that none were added after design. The contractor will pothole the various tie-in points to ensure the horizontal/vertical alignment is correct and also to confirm the existing material type and dimensions are correct. 10 a 1561:1 ...- Activities would be included in the contractor's CPM schedule for TCE Advance Notification and planned TCE usage activities. Once the Project has commenced and schedules are known, the CM team will ensure that both OCTAand the TCE owners (Western Exterminating and RICOH) were aware of the dates and the work activities that will be occurring. These dates will be checked each month for discussions with the 3rd parties and used to ensure advance notifications are sent out in a timely manner. Berg & Associates, Inc. 10
