LS2 I&I Reduction Program Phase 1

Some of the manholes look to be in good structural condition. Are they intended to be replaced per plan or will these be reviewed and assessed individual to determine the possibility for rehab instead of replacement?

1. Can you clarify the time allotted for completion (45 or 122 days)? Section 1.20 Time of Completion, page 9: “The Time of Completion of the work to be performed under this Contract is 122 Days calendar days commencing from issuance of the written Notice to Proceed.” Section 2.1 Bid Form, page 12: Bidder agrees to plan and prosecute the work so that all work is completed “forty-five (45) calendar days after issuance of the Notice to Proceed.”

2. Can you provide the County Right-of-Way Permit? The documents reference County Right-of-Way permit conditions, but I was unable to find a copy of that permit.

3. Can you provide additional information regarding property access? Please confirm: • Whether OLWS will provide the required property access/release forms • What form of owner authorization is required before work in easements or on private property • Whether signed releases are required before bid, before construction, or only before entering each property Reason for question: The contractor is required to coordinate with property owners and obtain signed release forms, but the required form and process are not provided. Reference: Item 1 Mobilization, page 15-16.

Can you please clarify the requirements for Bid Item 6 – Vibration Monitoring? This would include: • Governing vibration standard and allowable limits • Required monitoring locations and duration • Whether continuous real-time monitoring is required during pipe bursting • Whether preconstruction condition surveys are required • Required reporting/documentation deliverables • Whether third-party professional monitoring services are required • Intended measurement and payment basis for the bid item (per monitored structure, per monitoring location, or per mob)
