2. Abatement activities will require air monitoring and observation. Contractor shall retain the services of an independent third party IH consultant to provide abatement project monitoring services.

3. The presence of racoons in Building 65 is evident. Pest control and proper removal of racoon waste may be required prior to abatement activities.

D. The Asbestos Removal Portion of this Project shall be in accordance with the Occupational

Safety and Health Act (OSHA) Section 29 CFR 1926.1101 Asbestos.

E. Air Monitoring for Class I and Class II shall follow OSHA requirements for perimeter verification during work and clearance monitoring in addition to the OSHA personal monitoring of asbestos abatement workers.

1.2 SECTION INCLUDES

A. Requirements for the removal of asbestos-containing materials. All asbestos material shall be disposed of as asbestos-containing material waste.

B. The definitions of specific terms used in these Specifications are verbatim with those of the

OSHA Section 29 CFR 1926.1101 Asbestos

1.3 OWNER'S RIGHT TO CARRY OUT THE ASBESTOS ABATEMENT WORK

A. If the Contractor defaults or neglects to carry out the activities applicable to the Asbestos Abatement

Work in accordance with the Contract Documents and fails within a 24-hour period after receipt of a written notice from the Owner to commence and continue correction of such default or neglect with diligence and promptness (collectively the "deficiencies"), the Owner may, without prejudice to other remedies the Owner may have, act to correct such deficiencies.

B. If the Contractor conducts the Work in a manner which would cause endangerment to public health or safety, the Owner may, without written notice, or prejudice to other remedies the Owner may have, require the Contractor to remedy the situation, or the Owner may act to correct same at the

Contractor's expense.

C. In the above cases, an appropriate Change Order or Construction Change Directive shall be issued deducting from payments then or thereafter due the Contractor the cost of correcting such deficiencies, including compensation for the Owner’s Consultants additional services and expenses made necessary by such deficiencies. Such action by the Owner and amounts charged to the

Contractor are both subject to prior direction and approval of the Owner’s Consultants. If payments then or thereafter due the Contractor are not sufficient to cover such amounts, the Contractor shall pay the difference to the Owner.

A critical consideration is the definition of the Work to be sufficient to allow for all Asbestos Abatement Work to be completed as part of one mobilization prior to the start of other Work on this contract. The Owner shall not be held responsible for delays and duplicative costs associated with the possible eventuality that the

Contractor needs to arrange for some Asbestos Abatement Work to be completed at a time following the initial Asbestos Abatement Work due to the Contractor’s failure to properly define and execute the Asbestos Abatement Work as part of that first mobilization. The Contractor shall be responsible for all consultant fees incurred by the owner due to insufficient work scope or failure to comply with the “Asbestos Abatement Deadline” defined elsewhere in these contract documents.

1.5 QUALIFICATIONS OF CONTRACTOR

A. The Contractor must be licensed (“A” license) by the New Jersey Department of Labor and

Workforce Development (LWD) as an Asbestos Removal Contractor and meet all requirements of the New Jersey Department of Health (DOH) and LWD as cited in N.J.A.C. 8:60 and N.J.A.C.

12:120, respectively or licensed and/or accredited by the EPA or another state per the EPA Model

Accreditation Plan.

1.6 INSURANCE

1. Contractor's asbestos abatement liability insurance in the occurrence form, $3,000,000.00 per occurrence, $5,000,000.00 aggregate.

B. The existence of the above insurance shall in no way relieve any Contractor or any Subcontractor of any responsibility for which they are liable in excess of the amount recoverable under the insurance provided above.

C. Any increase of limits of liability of any type of insurance not described above that any Contractor may require for its protection or on account of statute, shall be its own responsibility and at its own expense. Any policy covering any Contractor's own equipment against loss by physical damage shall include an endorsement providing that the underwriters waive their right of subrogation against the Owner, Architects, Construction Managers, Consultants, other Contractors or Subcontractors.

D. All insurance required by this Section or any other insurance required by the Contract Documents shall be provided by insurers acceptable to the Owner.
