1.5 SECURITY

Arrange site security with the District at the beginning of the job. Provide temporary security at building penetrations created by the demolition and abatement.

1.6. SPECIAL CONDITIONS

Air Sampling: 1. PCM Analysis: Analysis of PCM samples shall follow the procedures outlined in NIOSH

method 7400 and within these Contract Documents. 2. TEM Analysis: The U. S. Environmental Protection Agency passed regulations for schools

under the Asbestos Hazard Emergency Response Act (AHERA), which are found in 40 CFR Part 763 "Asbestos Containing Materials in Schools". These regulation states that all abatement work shall be evaluated upon completion by collecting air samples using aggressive sampling techniques and that all such samples shall be analyzed using Transmission Electron Microscopy (TEM). The TEM protocol for large projects/zones calls for the collection of a minimum of five (5) inside samples, five (5) outside samples, and three (3) blank samples and each should be analyzed by TEM. The regulation strictly defines the criteria that must be met to determine that a building is acceptably clean after removal. TEM analysis turnaround times shall be 24 hours, unless otherwise indicated.

3. The sampling and analytical criteria in the AHERA regulation for schools shall be viewed

as the preferred method for determining that any asbestos abatement project in any building has achieved a satisfactory level of cleanliness. The District shall clear all work areas using [aggressive] [static] sampling and TEM analysis, unless otherwise noted below. The District reserves the right to determine the quantity of clearance air samples and blanks to be collected for each subzone.

4. The District shall pay the Environmental Consultant's costs of the final round of visual

inspections, aggressive air sampling, and PCM and/or TEM analyses that will meet the asbestos abatement specification. All rounds of visual inspections, aggressive air sampling, and PCM and/or TEM analyses that fail to meet the contract criteria shall be

mailto:[email protected]





02 26 00-4

borne by the Contractor. For the purpose of this paragraph, visual inspection includes the area isolation inspection, pre-encapsulation inspection, and final area clean-up inspection.

5. During all asbestos-related work, perimeter sample results will be collected by the

District and/or their Environmental Consultant (Industrial Hygienist). These samples will be analyzed by Phase Contrast Microscopy (PCM). Sample results that are in excess of the background level or one hundredth fibers per cubic centimeter (>0.01 f/cc) Project Action Level may be forwarded for analysis by Transmission Electron Microscopy (TEM) with a twelve (12) hour turnaround specified. Handling, shipping, and analysis charges (including the Environmental Consultants time and expenses) will be paid for by the Contractor. Any sample results in excess of seventy asbestos structures per square millimeter (70 str/mm2) of filter area (corrected for a twelve hundred to eighteen hundred (1,200 - 1,800) liter sample volume as appropriate) will require cleaning, inspection, and resampling of the affected area at the Contractor's expense.

6. During all lead hazard-related work, such as demolition, torching and welding activities,

etc., as applicable, perimeter air sample and/or lead wipe sample results will be collected by the District's Environmental Consultant (Industrial Hygienist). These samples will be analyzed by flame atomic absorption. Wipe sample results which are in excess of the construction dust control standard of eight hundred micrograms per square foot (>800 µg/SF) for adjoining construction zones on two (2) consecutive samplings (or two (2) consecutive days) or forty 40 micrograms per square foot (>40 µg/SF) for adjoining occupied (floor) areas on any occasion will require isolation and clean-up of the affected areas. Air sampling results in excess of the Cal/OSHA "Project Action Level" of thirty micrograms per cubic meter (>30 µg/m3) will require isolation of the work area and amendment of work procedures and/or clean-up of the affected areas. Resampling of the affected areas and handling, shipping, and analysis charges (including the Environmental Consultant's time and expenses) for additional sampling required to show background levels below these construction lead standards shall be borne by the Contractor.

Submittals: 1. All pre-construction submittals shall be forwarded to the District’s Project Manager and

the District’s designated Environmental Consultant (Industrial Hygienist) in the Contract Documents and herein.

2. Failure by the Contractor to fulfill the submittal requirements as specified in the

Contract Documents and herein shall be the basis for withholding final payment until such submittal requirements are satisfied.

Additional Liquidated Damages: 1. The Contractor shall pay for all Environmental Consultant costs for delays in completion

of work beyond the authorized schedule established by the District. Such charges shall include Consultant's observations and inspections, daily air monitoring, equipment, transportation and analysis charges. Such costs are estimated at $1,200 per day, exclusive of any costs associated with final clearance air testing. See the Liquidated Damages Section in the General Conditions for further requirements.

Waste Manifests: 1. The Contractor shall coordinate the inspection and signing of all waste manifests with

the District and its Environmental Consultant, while on-site. Failure to complete the



02 26 00-5

manifests or callbacks after completion of the project will be backcharged to the Contractor.

Remove the mastics using an approved "low odor" mastic remover with greater than 140°F flash point. Dispose of tile waste as Category 1 non-friable waste. Characterize and dispose of rags and solvent residues as a separate hazardous waste stream. For Linoleum Flooring: Abate the vinyl floor sheeting (linoleum) using full isolation or mini-containment abatement methods per Cal/OSHA 8 CCR 1529 Work Class 2 procedures, minimum, with negative pressurization of the zone(s). Demolish interior partitions and counters to access and abate concealed materials. using wet methods and dispose of as friable asbestos waste. See Lead Hazards below for handling of non-ACM battleship linoleum flooring, where applicable. For Baseboard Mastic Abatement: Scrap 3-dimensional mastics on wallboard or plasters to allow for reinstallation of new baseboards. For Disposal & Cleanup: Double gooseneck bag all asbestos floor tiles as dispose as Category 1 non-friable waste. Dispose of ACM linoleum flooring as friable asbestos waste. Dispose of mastics, rags and associated waste as specified by the mastic remover manufacturer, potentially as hazardous waste. HEPA vacuum the surrounding area, prior to visual inspection by the Environmental Consultant.

Other Comments: For Exploration Cuts for Painted Substrates Post notices, including CDPH, Cal/OSHA and EPA RR&P notices, as applicable, prior to start of work. Because of the need for continuing occupancy of the building, all exploration work shall be completed within mini-containments under negative pressurization. Manually scrape and stabilize loose and peeling paints prior to demolition of painted substrates using drop cloths, wet methods, and HEPA vacuums for dust control in compliance with Cal/OSHA regulation 8 CCR 1532.11 and the EPA’s RR&P rules. Avoid dry sweeping. Burning of paints, use of heat guns greater than 1,100 deg. F, and use of leaf blowers or compressed air for clean-up are prohibited. Use of mechanical equipment, such as sanders, grinders and needle guns without a HEPA-vacuum attached thereto are prohibited for sites with children under the age of 6 as occupants (per EPA’s RR&P rules). Work areas shall be cleaned-up of lead hazards daily before leaving the site. For Disposal & Cleanup: Demolish and dispose of intact painted wall and ceiling substrates as non-hazardous waste. Characterize and dispose of loose and peeling paint debris, chemical strippers, rags, etc. as potential hazardous waste. Clean-up drop cloths and HEPA vacuum loose and peeling chips and debris daily for all work areas before leaving the site. Complete abatement work exceeding the permissible exposure limit using CDPH Certified Lead Workers and Supervisors, including but not necessarily limited to demolition of lead glazed ceramic tiles, extensive manual or mechanical scraping or sanding of loose and peeling paints, demolition of concrete-encased primed steel, and spot abatement of primed structural steel prior to torching or cutting, as applicable.
