SECTION 23 - DEMOLITION, RENOVATION AND RE-OCCUPANCY

23.A General.

23.A.01 Demolition and renovation activities must be performed in accordance with ANSI Standard A10.6, Safety Requirements for Demolition.

1. Prior to initiating demolition or renovation activities, the following survey and plan must be accomplished. > See lead and asbestos requirements in Section 06.C.
• (1) Engineering Survey. An engineering survey by a Registered Professional Engineer (RPE) must be performed of the structure to determine the structure layout, the condition of the framing, floors, walls, the possibility of unplanned collapse of any portion of the structure (any adjacent structure where employees or property may be exposed must be similarly checked), and the existence of other potential or real demolition hazards.

Note: The engineering survey is not required for soft demolition or renovation activities as long as no load-bearing structure will be removed or demolished.

• (2) Demolition/Renovation Plan. A demolition plan developed by a RPE and must be submitted to the GDA. Plan must be based on the engineering, lead and asbestos surveys and must intend for the safe dismantling and removal of all building components and debris. This plan is required for all demolition and renovation activities and must include, but is not limited to, the following basic elements:
  • (a)schedule; scope of work being accomplished;
  • (b)description of work methods, equipment, job site and key personnel;
  • (c)site preparation;
  • (d)Waste Management Plan to include Asbestos-Containing Materials (ACM)/Other Regulated Material (ORM) Abatement Plan;
  • (d)Site Restoration Plan and other requirements specified in a Statement of Work or as directed by the Contracting Officer (KO).
2. All employees engaged in demolition/renovation activities must be instructed in the plan so that they may conduct their work activities in a safe manner.

23.A.02 Electric, gas, water, steam, sewer, and other service lines affected as a result of project work must be shut off, capped, or otherwise controlled inside and outside the building line before demolition is started.

1. In each case, any utility company that is involved must be notified in advance.
2. The Contractor must provide the GDA and the Contractor's designated authority with an engineering drawing (e.g., site plans, utility plans) that indicates the location of all service lines and the means for their control.
3. If it is necessary to maintain any power, water, or other utilities during renovation, such lines must be temporarily relocated and protected.
4. It must be the responsibility of the facility owner to identify and field verify the point or points for disconnection and de-energizing electrical components and electrical service lines. > See Sections 11 and 12.
• (1) The Contractor must confirm that the disconnection or de-energizing has been performed prior to the start of the demolition process.
• (2) De-energized electrical service must be secured via a lock-out method and field verified by the contractor, per Section 12 and their HEC Program.
5. If the project includes the abandonment or demolition of existing gas lines, ensure that the existing lines are accurately located and the procedures and installations for removal or replacement are accomplished in accordance with applicable sections of 29 CFR 1926.850.
6. If the project includes fire suppression systems, the owner must provide to the GDA confirmation or verification that the Chemical Fire Suppression (CFS) system has been de- activated and that the chemical has been removed from the system prior to the start of the renovation/demolition process. If the CFS system is found to be active after demolition has begun, the contractor must immediately cease work and notify the GDA. The contractor must take no action to abate or remove the CFS system or components.

23.A.03 It must be determined if any hazardous building materials, hazardous chemicals, gases, explosives, flammable materials, or dangerous substances have been used in any building construction, pipes, tanks, or other equipment on the property.

1. When such hazards are identified, testing must be conducted to determine the type and concentration of the hazardous substance and test results must be provided to the GDA and the Contractor's designated authority.
2. Such hazards must be controlled or eliminated before demolition is started.
3. If Hazardous Materials (HAZMAT) are found on the project site or location after demolition has begun, the contractor must immediately cease work and notify the GDA. The contractor must take no action to abate or remove the HAZMAT without GDA approval.

23.A.04 All ACM and ORMs must be removed from structures in accordance with all federal and state laws before renovation/demolition begins.

1. ACM/ORM must be taken to a controlled landfill or other licensed disposal facility;
2. Construction and Debris (C&D) must be taken to a general waste landfill; and
3. Recyclable materials must be taken to a recycle yard or retained by the GOV.

23.A.05 When employees work within a structure to be demolished that has been damaged by fire, flood, explosion, or other cause, the walls or floor must be shored or braced IAW the Engineering Survey and Plan required by Section 23.A.02.
