TECHNICAL SPECIFICATIONS

1. DEMOLITION REQUIREMENTS
This project shall be completed in conformance with the Improvement Plans, Technical Specifications and Special Conditions of these contract documents which were prepared specifically for this project and supersede the City of Imperial Municipal mandatory construction and demolition recycling program ordinance prepared for private construction and demolition projects within the City of Imperial. The Technical Specifications and Special Conditions were prepared in accordance with the California Code of Regulations (CCR’s) including the California Green Building Standards Code.

During the preparation of the project design documents a Waste Management Report Identification of Construction and Demolition Debris (WMRIC&D) Chart was prepared.

The WMRIC&D Chart lists the known items compromising the different structures to undergo demolition. Separate WMRIC&D Charts were prepared for each structure to undergo demolition. The WMRIC&D Charts are included as Table “A” in the Special Conditions Section of the specifications.

During the project design, it was attempted to identify and place each type of demolition item on the WMRIC&D – Chart; however, there will likely be unknown below grade items or items which are not visible by observation which will be discovered and required to undergo demolition during the construction period. It is the responsibility of the contractor to review the as-built drawings, as referenced by the improvement plans, and conduct a field review during the bidding period to observe the demolition items on the WMRIC&D – Chart and identify any additional items which may require demolition during project construction.

Diversion requirements as listed in Technical Specification Item 4 require that 100 percent of inert material by weight and a minimum of 65 percent of Construction and Demolition debris (non-inert material) by weight be recycled, reused or salvaged. The weight of the materials on the WMRIC&D – Chart is therefore important and monitoring the weight of the different demolition materials removed from the project site during project construction is very important. The WMRIC&D – Chart prepared during the design period listed the City of Imperial – Wastewater Treatment Plant Demolition Project – THG #173.138

Page 3 of 21 ends

TECHNICAL SPECIFICATIONS
approximate calculated weight of a few of the demolition material items; however the weight of most of the items, such as the clarifier steel bridges, center wells or raker arms, were not possible to calculate and are not included on the WMRIC&D – Chart. The contractor will not be required to estimate the weight of the WMRIC&D – Chart items during the bidding phase, however; the contractor will be required to weigh each item load removed from the project site during project construction. The weight of each demolition material item leaving the project site shall be recorded on the Daily Recycling Log of Construction & Demolition (C & D) Material Chart – Table B.

The Daily Recycling Log of Construction & Demolition (C & D) Chart – Table B is contained in the Special Conditions section of the specifications. The Daily Recycling Log of Construction & Demolition (C & D) Chart – Table B includes eighteen columns. A Daily Recycling Log of Construction & Demolition (C & D) Chart – Table B Chart has been prepared for each project demolition structure. The Daily Recycling Log of Construction & Demolition (C & D) Chart – Table B shall be made current each day; except that copies of the weight slips and vendor receipts will be allowed to be delivered to the Construction Manager the day after the demolition material is delivered to the vendor. Column 16 requires the Construction Manager to initial and date each listed demolition item the day after the item is removed from the project site to verify all columns for a particular item have been satisfactorily completed. The Construction Manager shall require the contractor stop demolition work if the contractor does not maintain the Daily Recycling Log of Construction & Demolition (C & D) Chart – Table B current on a daily basis. The Contractor shall not be compensated for these work stoppages. There will undoubtably be existing unknown buried materials or other unknown materials which will be discovered during the project demolition. All previously unknown materials shall be included on the Daily Recycling Log of Construction & Demolition (C & D) Chart – Table B.

A Waste Management Summary Report – Table C Chart shall be prepared each Monday for the previous week’s demolition work. The Waste Management Summary Report – Table C Chart is contained in the Special Conditions of the specifications. The Waste Management Summary Report – Table C Chart includes thirteen column items. The City of Imperial – Wastewater Treatment Plant Demolition Project – THG #173.138

Page 4 of 21 ends

TECHNICAL SPECIFICATIONS
Waste Management Summary Report – Table C Chart will transfer weight related column information from the previous week from Table B to Table C. The Table C accumulative inert and non-inert diversion percentages will be calculated each week. If diversion percentages are not in conformance with the diversion goals the contractor shall determine on how recycling, reuse or salvage methods will be modified to bring the diversion percentages within the diversion percentage goals. The Construction Manager shall require the contractor stop demolition work if the contractor does not maintain the Waste Management Summary Report current on a weekly basis. The Contractor shall not be compensated for these work stoppages.

Quantity and weight estimates for several of the largest demolition item contributors were completed for several quantifiable items including the pcc concrete and ductile iron piping, valves, fittings and related items. The quantity estimates were completed to determine the rough, approximate weight of these materials and gain insight as to the magnitude of the demolition work. Many of the estimates are relying on as-built plans, which may not be completely accurate. There may have been construction improvements completed over the last 40 years for some of the buried or unobservable items which were not recorded (but will require demolition). The quantity and weight estimates are to be considered rough and accurate within 40 percent of the calculated weight of a particular item designation. The quantity and weight estimates are included as Table D documents in the Special Conditions section of the specifications.
