The Government will handle all fiber optic cabling runs and connections. All work must comply with Joint Base Andrews Design Compatibility Guidelines, International Building Code, National Electrical Code, NFPA standards, and OSHA requirements.
The contractor must designate an on-site contract manager available within 60 minutes during normal duty hours (7:00 a.m. to 4:00 p.m., Monday–Friday, excluding federal holidays) and within three hours after hours, with 24/7 telephone availability.
