Background.

This Statement of Work (SOW) outlines the requirements for demolishing two brick buildings, designated as Building 149 and Building 150. Both buildings have experienced a complete roof collapse causing substantial damage to the supporting walls. The extent of the damage renders the buildings irreparable, necessitating complete demolition of roof structure, and exterior supporting walls. Building 149 is located in a large courtyard surrounded by other structures and connecting corridors, which necessitates additional access and demolition considerations.

Scope. The contractor shall supply all necessary labor, materials, equipment, and services to execute the following tasks:

Demolition. Demolition of Building walls and roof system in their entirety.

Utility Removal and Termination.

Removal and safe termination of steam and condensate return lines in each building at their source.

Removal and safe termination of electrical systems in each building at their source.

Removal and safe termination of water supply in each building at their source.

The contractor shall provide a detailed Utility Shutdown Plan outlining the steps and precautions for safely shutting down, de-energizing, and terminating all utilities for these two buildings.

Retention of Structural Elements.

The concrete floor of each building is to be protected and preserved.

Sidewalks adjacent to both buildings are to be protected and preserved.

Tunnels with concrete lids are to be protected and preserved.

Temporary Fencing.

Installation and maintenance of temporary fencing around the entire perimeter of the demolition sites for both Building 149 and Building 150 for the duration of the project .

Fencing must be a minimum of six (6) feet high and secured to prevent unauthorized access.

Clearly marked construction site signs to be placed on the fencing to indicate restricted access and necessary safety precautions.

Construction Waste Documentation.

The contractor shall document all construction waste generated during the demolition process.

Provide documentation to the COR detailing the types and quantities of construction waste, including disposal methods and locations.

Adherence to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for any potential hazardous substance releases and required reporting.

All activities must be conducted under the supervision of qualified and certified personnel, ensuring complete adherence to these standards and regulations. Detailed records of compliance shall be maintained and available for review upon request.

The contractor shall implement a site-specific safety plan addressing all potential hazards, including the safe removal of materials of unknown type and quantity buried under the roof debris.

Utility Termination.

The contractor shall verify, ensure, and coordinate the proper disconnection and termination of all utility lines, including steam, water, and electricity associated with these two buildings. This involves collaborating with relevant utility providers, conducting thorough inspections to confirm disconnections, and implementing safety protocols to prevent any accidental utility service disruptions or hazards during the demolition process.

The contractor shall obtain all necessary permits and approvals required for the termination of utility services. This includes coordinating activities with Engineering and effected services, submitting detailed shop drawings and documentation, and ensuring compliance with all relevant regulations and codes for the safe disconnection of utilities such as water, electricity, and steam lines.

The contractor is strictly prohibited from performing any electrical hot work under any circumstances. Prior to commencing any demolition or construction activities, all electrical systems must be completely de-energized. This process includes isolating and shutting down power sources, locking out and tagging out all electrical circuits in accordance with OSHA Standard 29 CFR 1910.147 for the control of hazardous energy, and thoroughly verifying that the area is safe to work in through proper testing and inspection procedures as outlined in NFPA 70E. Additionally, the contractor must maintain documentation confirming that these safety measures have been implemented and adhered to, including compliance with the National Electrical Code (NEC) and other relevant federal, state, and local regulations.

The contractor is required to provide a comprehensive Utility Shutdown Plan that outlines the specific steps and precautions for safely shutting down, de-energizing, and terminating all utility services. This plan must adhere to all relevant regulations and standards, including but not limited to OSHA Standard 29 CFR 1910.147, which covers the control of hazardous energy (lockout/tagout) procedures, and NFPA 70E for electrical safety in the workplace.
