Identify what buried human-made obstructions may exist that are not feasible to detect at this stage that could be encountered in the Trenchless alignment. 2. Identify what subsurface materials were encountered during HDR’s field investigations we should become familiar with on this project that could be encountered in the Trenchless alignment. 3. Please direct us to where we can find the as-built plans of existing and abandoned utilities we should become familiar with on this project that could be encountered in the Trenchless alignment. 4. Identify the Origin and properties of the gravels and possible cobbles and boulders that may be encounter in the Trenchless alignment. 5. Identify the unconfined compressive strength range of the gravels and possible cobbles and boulders that may be encounter in the Trenchless alignment. 6. Identify the gravels and possible cobbles and boulders ratio’s you anticipate the Microtunneling Machine may encounter in the Trenchless alignment. 7. Identify the maximum size and quantity of cobbles and boulders that may be encounter in the Trenchless alignment. | Answered in Addendum 3 | | Received from Nada Pacific Corporation on 7/15 via email: We request the Owner revise the RCP Jacking Pipe requirements to be consistent with the ASCE Standard Design for Construction Guidelines for Microtunneling 36-15 for Non pressure RCP Pipe and require ASTM C76 Class V Wall-C / ASCE 27-00 in 10-foot lengths. We believe utilizing the same RCP pipe for the entire project will prove to be more cost-effective alternative saving the rate payers money. | Answered in Addendum 3 | **Addendums**: | Addendum | Date | Note | |---|---|---| | Addendum No. 1 | 07/07/2026 03:38 PM EDT | | | Addendum No. 2 | 07/13/2026 07:57 PM EDT | | | Addendum No. 3 | 07/20/2026 08:02 PM EDT | | **Communications**: - Communication No.4: Attached is the sign-in sheet from the Mandatory Pre-Bid Meeting and Job Walk held on July 23, 2026. — Pre-Bid Sign-in.pdf - Communication No.3: Prospective bidders are reminded to review the Contract Documents, including Agreement Page A-2 as revised by Addendum No. 3, regarding Contract Time and project completion requirements.
