About this file
This is a Phasing Narrative for a federal construction project involving network infrastructure upgrades at a VA facility in Dallas, Texas (Project 549-21-700).
The project is organized into three sequential phases focused on installing fiber optic cabling with redundant A and B path ring topology across campus. Phase 1 establishes the backbone infrastructure by locating and extending a secondary Internet Service Provider (ISP) from Ann Arbor near building 9 to building 77, then extending through duct banks to building 2J Server Room. This phase includes installing fiber optic termination cabinets in the 2J Server Room and providing new fiber cabling to account for all critical and essential buildings (1, 2, 2J, 3, 8, 60, 72, 74, and 87), with fiber left reeled and ready for distribution in Phase 3. Phase 1 also completes the redundant fiber ring topology across campus through duct banks to all other buildings, with all Outside Plant (OSP) work finished by phase end. Phase 2 addresses ancillary and non-critical buildings (5, 6, 7, 8, 9, 11, 13, 44, 45, 68, 69, 71, 75, 77, 79, 80, 81, 82, and temporary buildings TT46-TT55 and Herzog buildings), working one building at a time until substantial completion, including demolition work, TR/TE construction or modification, connection to the fiber ring topology, and horizontal cabling from TRs to edge devices. Phase 3 completes fiber installation within critical and essential buildings, beginning with building 60, requiring TR construction or modification, demolition work as needed, connection to redundant fiber paths, and horizontal cabling, with strict requirements that no horizontal cabling demolition occurs until new edge devices are installed and cabled from the new TR infrastructure. The miscellaneous provisions allow schedule deviations for grouped off-hours work and require Electronic Security Systems work to be completed during TR construction.

Phase 1
• Locate and extend secondary ISP that enters campus from Ann Arbor (near building 9) to building 77 new TR/ISP entrance facility.
o Extend ISP through duct banks from building 77 to building 2J Server Room to establish secondary ISP for campus.
• Install new fiber optic cabling termination cabinets in 2J Server Room for A and B fiber optic cabling pathways required for ring topology.
• Provide new fiber optic cabling from cabinets to account for all buildings, levels, and rooms within the critical and essential buildings (1, 2, 2J, 3, 8, 60, 72, 74, and 87).
o Leave fiber reeled and ready for distribution through the critical and essential buildings in phase 3.
• Install new fiber optic cabling redundant A and B path fiber ring topology across campus through duct banks (existing and new) to all other buildings.
o All OSP work to be completed under Phase 1.
Phase 2
• Complete all work on for ancillary buildings (non-critical or essential buildings) o Buildings 5, 6, 7, 8, 9, 11, 13, 44, 45, 68, 69, 71, 75, 77, 79 (fiber to existing rack only), 80, 81, 82, TT46, TT47, TT48, TT49, TT50, TT51, TT52, TT54, TT55, and all (3) Herzog buildings.
▪ Working in one building at a time until substantial completion (installed, tested, and approved).
• Complete all demolition work o Build new TRs/TEs or modify existing TRs in place as required o Connect TRs to redundant A and B path fiber ring topology.
o Complete all horizontal cabling work to edge devices from
TRs

Phase 3
• Install fiber optic cabling for redundant A and B path fiber ring topology each TR within the critical and essential buildings.
o 1, 2, 2J, 3, 8, 60, 70, 72, 74, and 87
▪ Build new TR/TE or modify existing TRs in place as required in each building.
• Complete demolition work as needed to install new.
o Working in one building at a time until substantial completion
(installed, tested, and approved).
o Connect TRs to redundant A and B path fiber ring topology.
o Complete all horizontal cabling work to edge devices from
TRs
▪ No horizontal cabling demolition work shall take place until new edge devices are installed and cabled from new TR supported from new backbone infrastructure.
• Contractor to start with building 60 and work their way in to the main grouping of buildings
Miscellaneous
• Deviations from schedule allowed for “off” hours work that can be reasonably grouped together
• All Electronic Security Systems (ESS) work associated with TRs shall be done during the construction of the TRs.
