BAE Response:

The note is instructing the contractor that if there are any devices that are installed in the ceiling (including but not limited to, balancing dampers, valves, filters, motors, etc) that required access for either maintenance or servicing, they should be installed in such a manner that they can be accessed and serviced.

1. The Horizontal Cable Distribution Schedule on sheet 01-ET100RP (typical of all plans with this schedule) lists quantities of cables to be removed and replaced. Please confirm that we are to re-use existing raceways stubbed out at device locations.

BAE Response:

Use only new raceways and conduits.

1. The Horizontal Cable Distribution Schedule on sheet 01-ET100RP (typical of all plans with this schedule) lists quantities of new cables to be installed and lists these as “allowance”. It is unknown where these cables are to be routed, how many cables per drop location and if and where new conduit is required.

BAE Response:

The Contractor is to field verify cable quantities, routes, and cables per TCO instance.

1. Please provide cable distances and the quantity of new conduit stubs that are required for each plan schedule that lists these additional “New”cable drops.

The Contractor is to field verify cable quantities, routes, and cables per TCO instance.

1. For the new cable drop locations as shown on the “Horizontal Cable Distribution Schedule” throughout the plan set, how are we to price out the new raceway installations in existing walls. The VA has not provided the locations and wall finishes and types for these additional “allowance” drop locations. For bidding purposes, please provide a wall type, and existing finish to be used as a baseline to bid these new drop locations.

Walls can be assumed to be sheetrock, metal studs, and painted finish unless otherwise noted. Differing conditions when onsite will need to be RFI’d.
