| The typical notes indicate to frame new walls and/or extend existing walls of the electrical rooms to the deck above. Some of the new electrical rooms will be built in areas with a high deck above that have mechanical ductworks, and utility pipes crossing the area of the electrical rooms. If walls are built to the deck, and the ceiling of the electrical rooms is open to the deck as required per specs, then the ductwork and pipes will only be accessible through the room, and the electrical equipment will be exposed to any possible leak. Please clarify if this is the design intent for these rooms or if a lower watertight roof should be built to protect/enclose the electrical rooms. |

| Ref# (1383-70T-602)(1383-70T-603)(1383-70T-604) - Are any of the backbone runs shown on the site plan new fiber runs or are all runs existing fiber to remain? For the new IT rooms in outbuildings what are the requirements for backbone runs? Do the runs go to the nearest IT Room or all the way back to BH-111? |
| Existing backbone fiber shown on the site plan shall remain. Inside Plant outbuilding fiber shall be extended and/or relocated to the new TR. |

| 70T-001Telecom Symbols - On telecommunications plans all locations are shown with a half shaded triangle? Are these locations to receive (4) cables each or is each locations to receive the amount of cables shown on the cable schedules. Example on the schedule if a (2) port location is shown does it receive (2) cables or (4)? |
| Cables shall be replaced like-for-like to match the existing quantity.See T-701 series sheets for quantities. |

| Ref# 1383 70T-441 - Keynote 5 says cabling, counduits, and wireways are to remain. Does this mean all cabling to this IT Room stays in place and no cabling coming out of this IT Room is to be replaces with new cat6a? |
| Existing conduit, raceways, cable tray etc. shall remain to serve all existing/ancillary Division 27 and Division 28 systems. The data cable itself is being replaced and served at the new locations. |

| Ref# 1383 70t-607 - Are any backbone runs from new IT Rooms going back to BH-111 or are fiber cables to be spliced from the nearest IT Room. Example 4C-102, does the run of (2) 24-strand SM fiber cables run all the way back to BH-111 or do we intercept the run from 4B-119 and splice the existing run that goes from 4B-119 to BH-111? |
| Homerun fiber back to BH-111 will remain. Intercept/fusion splice and relocate as indicated to serve the new locations. |

| Ref# 1383-70T-501, detail F4 and 70E-701 table - Electrical Grounding Diagram discusses establishing the system at the service entrance, the VA electrical service entrance is in building 69, in building 70 there are 13-unit substations. Where do you want to establish the grounding system for the primary busbar, should it be from the new electrical room in the penthouse? What size cable is required from said point to the new primary busbar? |
| Serve Entrance location varies with each building and will be field verified. Contractor shall submit coordination drawings with proposed route. Cable shall be sized per Specification 27 05 26 and NEC requirements. |

| Ref# 1383-70T-501, detail F4 and 70E-701 table - Detail F4 shows a "TBB" and a "BBC" conductor ran horizontally between all new TRs, on which floors do you want this horizontal "TBB" or "BBC" conductors? 1st and 4th? The upper conductor is labeled as "BBC" and the lower one is labeled as "TBB", note B says the "TBB" conductor is to be continuous, can we assume that is only continuous from basement to 4th level or should it also be on the lower level horizontally between TRs? Again, for these horizontal cables what size is required, 750MCM copper? |
| Follow Notes B and C for TBB and BBC locations. Cable shall be sized per Specification 27 05 26 and NEC requirements. |
