If the Contracting Officer directs the contractor to perform tests, and/or the material is found to be of a hazardous nature requiring additional protective measures, a contract modification may be required, subject to equitable adjustment under the terms of the contract.

The contractor is advised that friable and/or non-friable asbestos-containing material may be encountered in project areas.

Non-friable asbestos containing materials are materials in which asbestos fibers are bound by a matrix material, saturation, impregnation, or coating. Non-friable asbestos containing materials do not normally release airborne asbestos fiber during routine handling and end-use.

However, excessive fiber concentrations may be produced during uncontrolled abrading, sanding, drilling, cutting, machining, removal, demolition, or other similar activities. 29 CFR 1910.1001 shall be referenced in the event asbestos-containing materials are encountered. Friable asbestos-containing materials are not authorized for use in new construction or maintenance projects.

D. Salient characteristics of the materials proposed for use shall be clearly identified in the submittal and must match the salient characteristics as stated in Scope of Work, Specifications, Drawings and/or other documentation.
