II. CONTRACTOR SECURITY/WORKING REGULATIONS

A. Work Hours:

Work Hours for the contractor are 7:00 AM – 4:00 PM, Monday - Friday, excluding weekends and federal holidays. Any work required to be completed at any other time than noted above must be requested in writing to the COR five (5) working days prior to the start of the work. In the event of any equipment being replaced that would result in downtime of the normal orderly running of the institution, alternate work hours may be authorized in accordance with the time frame stated above.

Access to the site will be available during normal working hours except during emergencies. It shall be the responsibility of the Contractor to familiarize himself, his employees, and his subcontractors of the working hours and conditions in at the facility, as working hours may not constitute a full eight-hour workday. The Government assumes no responsibility to the Contractor nor to any of his subcontractors for shorter hours due to institutional emergencies or entry and/or exit of workers necessitated by normal institution routines.

B. Delivery of Materials:

All construction materials/equipment required for work on this project is required to be processed by the Contractor and coordinated with the institution COR for temporary storage.

Any construction related deliveries which are directly shipped to the contractor can be received between the hours of 7:00 a.m. to 12:00 p.m., Monday through Friday, excluding Federal Holidays.

All tools will be inventoried prior to beginning work and will be inventoried back in to ensure accurate accountability when leaving at the end of each work day.

Materials cannot be stored at a height that would create a fall hazard. All tools will be inventoried prior to entering the Institution. At the start of each work day all tools will be inventoried out on a daily tool inventory sheet and at the end of the work day all tools will be inventoried back in to ensure accurate accountability of all tools at the end of each work day.

All contractor owned extension cords that will be used during the project, regardless of length, shall be in good condition with no broken outer Insulation. Extension cords are considered a “high risk” tool having a Federal Bureau of Prisons’ tool classification of Double A.

It is the responsibility of the contractor to provide all PPE equipment. All ladders regardless of the size shall be stored, and secured to a stationary fixture with a chain and lock in a predetermined area, in a way that they cannot be removed. If ladders are required, immediately consult with the COR to ensure that he or she can make timely notification to appropriate institution staff. All extension cords regardless of length shall be in good condition with no broken outer insulation and will be secured in a locked construction gang box.

Should a system require Lock-out/Tag-out, the system will be required to have both Contractor and MDC Los Angeles locks on the isolation point to prevent shock. All Lock-out/Tag-out procedures will be in compliance with the institution Lock-out program.

F. Additional Considerations:
