This is Addendum No. 1 to the contract documents for the Rancho Los Alamitos Transmission Main Abandonment Project (MC-5264) issued by the Long Beach Public Utilities Department on August 13, 2026. The addendum provides clarifications, additions, and deletions to the construction plans and specifications for the abandonment of approximately 2,050 linear feet of existing 24-inch steel cylinder concrete transmission main in Long Beach, California. Key modifications include the addition of traffic control plans as new sheets 8 and 9, revisions to the table of contents and general notes, updates to specification sections covering cement mortar, metal fabrications, asbestos cement pipe (ACP) handling procedures, traffic control and temporary restriping, selective site demolition, paving removal and resurfacing, utility pipeline removal or abandonment, cast-in-place concrete, trenching and backfilling, and disinfection of water utility pipelines. The addendum extends several submittal requirements, including detailed specifications for line-stop equipment showing sleeve or wrapper plate, completion flange, line-stop assembly, dimensions, materials, pressure ratings, welding details, concrete support, thrust restraint, and connections to existing pipeline, as well as procedures for field verification of existing steel-cylinder thickness and condition, welding to existing pipe, and restoration of interior lining and exterior coating. Related work sections added include water service bypassing, governmental safety requirements, and connecting to existing pressure pipelines.

The addendum addresses hazardous materials handling procedures specific to asbestos-cement pipe connections in accordance with Cal/OSHA, United States Environmental Protection Agency (US EPA), and governing health agency requirements, referencing applicable California Code of Regulations and South Coast Air Quality Management District Rule 1403. Revised submittal procedures now require a Pipeline Abandonment Work Plan with professional engineer stamp, along with detailed calculations demonstrating that the line-stop assembly, completion flange, temporary support, concrete support, and thrust restraint are adequate for the pipeline working pressure and 188 PSI hydrostatic test pressure. The coordination section has been amended to extend the advance shutdown notification period from 45 days to 48 days. Thrust block design requirements specify an allowable soil-bearing capacity of 2,000 psf in accordance with LBUD Standard Drawing WDS-107, with provisions for revised design calculations if field conditions indicate different bearing capacity. The specifications for cast-in-place concrete, trenching and backfilling, and disinfection of water utility pipelines have been replaced in their entirety to reflect updated requirements and methodologies for the abandonment project.

NOTES:

1. PROPERTY BOUNDARIES, RIGHT-OF-WAY LIMITS, LOT LINES, EASEMENTS, AND

EXISTING UTILITY LOCATIONS SHOWN HEREON ARE BASED ON AVAILABLE RECORD

DRAWINGS AND GIS DATA PROVIDED BY LBUD AND HAVE NOT BEEN VERIFIED BY FIELD

SURVEY. THESE FEATURES ARE APPROXIMATE AND ARE PROVIDED FOR REFERENCE

ONLY. CONTRACTOR SHALL FIELD VERIFY THE HORIZONTAL AND VERTICAL LOCATION

OF ALL UTILITIES AND OTHER EXITING CONDITIONS, INCLUDING PROPERTY LINES AND

EASEMENTS, AS NEEDED PRIOR TO CONSTRUCTION. ANY DISCREPANCIES SHALL BE

BROUGHT TO THE ENGINEER'S ATTENTION FOR RESOLUTION.

2. CONTRACTOR SHALL TAKE ALL PRECAUTIONARY MEASURES TO PROTECT IN PLACE

AND SUPPORT ALL EXISTING UTILITIES WITHIN PROXIMITY UNLESS OTHERWISE NOTED.

3. CONTRACTOR SHALL DISINFECT AND PERFORM BAC-T TEST PIPING, INCLUDING ANY

PIPES AND LATERALS DISCONNECTED AND RECONNECTED, PER ANSI/AWWA C651-23,

PRIOR TO RECONNECTION PER AGENCY REQUIREMENTS. FOR LATERALS,

DISINFECTION AND TESTING SHOULD BE MINIMUM UP TO THE NEAREST VALVE OR AS

REQUIRED BY LBUD. SEE SPECIFICATION SECTION 33 13 00 FOR CHLORINATION OF

WATER MAINS FOR DISINFECTION.

4. CONTRACTOR SHALL SUBMIT TO LBUD A WRITTEN REQUEST TO DEWATER THE

PIPELINE TWO (2) WEEKS IN ADVANCE OF THE VALVE REPLACEMENT. LBUD WILL BE

RESPONSIBLE FOR CLOSING ALL THE DESIGNATED SHUT-DOWN VALVES AND THE

CONTRACTOR WILL BE RESPONSIBLE FOR DEWATERING THE PIPELINE. THE

CONTRACTOR SHALL BE EXPECTED TO PUMP OUT REMAINING NUISANCE WATER IN

THE PIPE AND DISCHARGE THE WATER TO EXISTING STORM DRAIN CATCH BASINS.

5. EXISTING LARGE GATE VALVES AND CONCRETE ANCHOR BLOCK UNDER THE VALVE

BODY TO BE REMOVED. CONTRACTOR TO REMOVE AND DISPOSE OF THE CONCRETE

ANCHOR BLOCK.

6. CONTRACTOR TO ABANDON EXISTING ACCESS MANHOLE, BY REMOVING LID, RISER,

TOP 2-FEET OF CONCRETE MANHOLE AND BACKFILL AND COMPACT. THE VOID MUST

BE FILLED WITH APPROVED MATERIALS, SUCH AS TYPE II BORROW OR FLOWABLE FILL,

AND COMPACTED TO MEET 90-95% RELATIVE COMPACTION. THE ABANDONED AREA

MUST BE BACKFILLED TO EXISTING GRADE IN UNDEVELOPED AREAS OR PAVED PER

CITY STANDARD IN DEVELOPED AREAS.

7. A POTHOLE INVESTIGATION WAS PERFORMED AT SELECT LOCATIONS ALONG THE

PROJECT ALIGNMENT TO BETTER INFORM EXISTING SUBSURFACE CONDITIONS, WITH

ONLY PARTIAL CONFIRMATION VERIFIED. THE CONTRACTOR SHALL NOT RELY SOLELY

ON THE POTHOLE DATA FOR CONSTRUCTION AND SHALL PERFORM INDEPENDENT

VERIFICATION OF ALL EXISTING UTILITIES AND SUBSURFACE FEATURES AS

NECESSARY TO COMPLETE THE WORK. SEE APPENDICES IN SPECIFICATIONS FOR

FULL POTHOLE REPORT AND SUPPORTING DOCUMENTATION.

8. CONTRACTOR TO FIELD VERIFY THE STEEL PIPE CYLINDER THICKNESS AND ASSESS

THE CONDITION OF PIPE PRIOR TO WELDING. CONFIRM PIPE IS INTACT AND

SUFFICIENT STEEL THICKNESS EXISTS TO SUPPORT PROPOSED WELDING

OPERATIONS AS SHOWN IN THE PLANS.
