SEWER LATERAL REPLACEMENT PROJECT (SLRP)

SPECIAL PROVISIONS

IFB No. 26XXXX These Special Provisions supplement the General Conditions and shall govern in the event of inconsistency. Defined terms shall have the meanings assigned in the General Conditions unless modified by these Special Provisions.

SECTION 1 – WATER INTRODUCTION REQUIREMEMTS FOR CCTV INSPECTIONS

The City requires the Contractor to perform water introduction during both pre-construction and post-construction Closed-Circuit Television (CCTV) inspections to ensure optimal lateral inspection quality in identifying defects such as cracks, leaks, sags, and blockages. Water introduction shall be carried out in compliance with Section 2739 of the Technical Specifications, using controlled flow rates to minimize water consumption while maintaining standards. For dry laterals, a low flow rate of approximately 15 to 30 gallons per minute (gpm) shall be used, and for wet laterals, a reduced flow rate of approximately 10 to 20 gpm shall be used, or as approved by the City. The water introduction ensures the pre-construction CCTV inspections assess the condition of the existing sewer lateral and the post-construction CCTV inspections verify the integrity of the newly installed sewer laterals. To avoid blocking the CCTV camera view, water shall be introduced prior to the CCTV lateral inspection.

SECTION 2 – CCTV INSPECTION AND RECOMMENDATION OF LATERAL REPLACEMENT METHOD

In accordance with Section 2739 of the Technical Specifications, the Contractor shall perform pre-construction CCTV inspections of the sewer laterals. CCTV results shall be used to determine the appropriate sewer lateral installation method as described in Section 3. Pre-construction sewer main CCTV is required to locate the lateral tie-in location. The City does not require PACP defect report.

Based on the pre-construction CCTV findings, the Contractor shall recommend a replacement method for existing laterals. The Contractor’s installation recommendation shall be submitted to the City for review. The City will assess the recommendation based on technical feasibility, constructability, potential system impacts and compliance with the Technical Specifications and City of Palo Alto (CPA) Water Gas Wastewater (WGW) Utility Standards. No replacement method shall proceed without written approval from the City prior to construction.

Following lateral replacement, the Contractor shall perform post-construction CCTV inspection for the sewer laterals. The City shall evaluate the completed work through post-construction CCTV inspection. The City reserves the right to reject any work that does not meet project requirements, one (1) year from the date of completion, in accordance with IFB Part 5 General Conditions, subparagraph 12.2.1.

SECTION 3 – INSTALLATION METHOD

The City’s objective is for new sewer laterals to be installed utilizing a pipe bursting method of installation to minimize excavation. The Contractor shall not proceed with any alternative lateral installation methods without written approval from the City prior to construction and installation.

An open-cut method of installation may be accepted by the City in the following situations:

1. Per Section 2737 of the Technical Specifications, Section 1.04, the City’s objective is for new sewer laterals to be installed perpendicular to the existing sewer main whenever possible. Prior to commencing work, the Contractor shall pothole the existing sewer lateral to verify horizontal alignment and to determine whether correcting the alignment to a perpendicular connection is feasible, considering existing site constraints and obstructions. If lateral alignment correction is feasible, the new lateral shall be installed perpendicular to the existing sewer main by an open cut installation upon City’s approval of the new alignment and installation method. The existing lateral shall be abandoned, and payment shall be made in accordance with the applicable bid item unit price. If lateral alignment correction is not feasible, the new lateral shall be installed following the same alignment by utilizing pipe bursting method of installation.

2. Prior to commencing work, the Contractor shall perform pre-construction CCTV inspection of the existing sewer lateral in accordance with Section 2739 of the Technical Specifications. If the CCTV inspection determines that the existing lateral has sags that cannot be corrected during the pipe bursting installation of the new lateral, the new lateral shall be installed by an open cut installation upon City’s approval of the new alignment and installation method.

If the approved open cut installation method proves ineffective due to unforeseen subsurface conditions encountered during construction, the Contractor shall stop work, notify the City, and submit a revised installation proposal for approval prior to resuming work. Any costs, delays or rework resulting from failure to follow this process shall be the responsibility of the Contractor.

SECTION 4 – UNDERGROUND SERVICE ALERT (USA)

This provision modifies IFB Part 5 of the General Conditions, Section 3.28.1. Replace the five-day notification period with a minimum of ten (10) Working days advance notification to Underground Service Alert (USA) by calling 811 prior to any excavation work. The Contractor shall delineate the work areas with white paint and only the request utility markings at those locations where underground work will occur during the following month.

SECTION 5 – PROJECT HOURS OF WORK

The construction hours for this Project are 8:00 AM to 5:00 PM, Monday through Friday. No work shall be performed beyond the defined work hours, unless approved by the City. The Contractor must refer to the City’s Traffic Control Requirement.

Additional time restrictions may apply when work occurs within (1) downtown areas, business districts, arterial streets, (2) bicycle lanes, or (3) within 1,500 linear feet of school grounds or along designated school routes. Appendix M provides the list of lateral addresses including working time restriction categorization specified above.

Following table provides summary of working hours restrictions:

Appendix C provides more detailed description regarding the working hours restrictions when working in downtown areas, business districts, arterial streets, bike lanes, or near schools.

No work shall be permitted along school routes during the first week of school. If the work area is within City specified school routes during the first week of school, the Contractor must schedule their Work to avoid these routes. The anticipated start of school dates for the 2026-2027, 2027-2028, and 2028-2029 school years can be found in Appendix B.
