Background:

On 06/20/2017 FAA Engineering Services visited Brooke Virginia BRV VOR to perform a site survey in order to develop a general plan to refurbish and repair the facility. Richard Polk AJW-2E15J from the Atlanta Engineering Center was accompanied by Steve Gowen WEX32-RIC from Richmond SSC during inspection.

Report:

BRV VOR is 75 miles North of Richmond SSC and, 46 miles South of the Manassas Airport. The entrance driveway is 7.5 miles East of I-95 off State Rd 604. Entrance drive is a 300’ long gravel road. Facility is located in a wooded area. Facility serves as a primary duty location for AF Technicians.

BRV is a mountain top VOR facility. There is a standalone VOR equipment building, VOR/TACAN antenna w/teepee, 16 mailbox monitor antennas, two fold over antenna poles, one cellular phone extender antenna pole, 500 gallon diesel tank, utility transformer, abandoned XFMR enclosure, retaining wall, well, septic drain field, and stairs located on site. Inside equipment & storage room are racks that contain VOR, TACAN DME, RTR & RCO equipment plus various receivers, monitors, amps, battery chargers, & other items. There is a UPS that contains 18 lead acid batteries inside equipment room.

The equipment building is 36’ x 36’ with a 40’x 40’ roof. Roof has a unique design. It has a slight pitch from a ½’ crown down the middle. Otherwise, it is flat. It has no gutters. There is a 1’ drip edge w/overhang.

Exterior walls are 9' 10” high with 6” lap vinyl siding covering. Building contains five rooms. Equipment, Storage, EG room, Office, & Bathroom. Interior walls & ceilings are the original masonite. There are three exterior metal doors.

There is very little evidence of moisture damage inside the building. Technician reports that this building doesn’t leak. Interior finishes are in reasonably good condition. Interior paint on walls is in good condition.

Interior floors are in fair condition.

The roof is in fair condition. It has an unusual type of membrane. Some kind of hard granular concrete surface. The subsurface deck & insulation are wavy and, not flat. There is some water ponding. It’s trimmed out with a galvanized steel drip edge on all four sides. A 2007 UIS Assessment Program Report says that an asphalt membrane roof was installed in 2002. Pictures from that report don’t match what is there now. 2007 Report contains images of a modified bitumen membrane. Difficult to tell how old the existing roof is.

There are (2), 3 ton, ICP, pad mounted, package unit HVAC’s providing conditioned air to building.

Units were installed in 2015 and, in good condition. There are four electrical distribution panels inside building.

Main Panel A and Sub Panel A, B, & C are either modern Square D, NQOD or GE AQF type. In good condition.

Probably installed in the last few years.

There is a 30KW Kohler, 3ph, diesel EG set inside the building with day tank, transfer/bypass switch, main disconnect & Veeder Root monitoring system.

Overhead power lines go underground at the beginning of gravel entrance road. There’s a small pad mounted utility transformer inside the perimeter security fence entrance gate. A 500 gallon diesel tank is also located on the East side of building.

Tree growth is encroaching on VORTAC antenna and, signal loss has been reported. Site needs to be cleared of unwanted trees. FAA will require contractor to use rotary disc mulching procedures on unwanted vegetation.

There are several drawings that describe BRV VOR site & building in the database. There are also some drawings for the RCO and RTR. Drawings that call out the legal boundaries of property are dated 12/03/1956. Drawings indicate significant building upgrades in 1985. RTR installation in 1988. And, RCO upgrades in 2015. FSEP report indicates a commission date of 1957. That would make this building about 61 years old.

2. Include gate & fence repair, teepee & mailbox cover replacement, pull box covers, gravel and, tree grinding & removal 3.Tree removal is a top priority.

4. Discuss project with EOSH. Locate the current asbestos report or procure funding for asbestos testing.

Determine if asbestos abatement will need to be added to SOW.

5. Produce a narrative scope of work document to include with drawings that can be advertised for bid offers.

6. Obtain construction project funding authorization.

7. Work with the FAA Procurement system. Locate at least three qualified construction contractors and, ask for bid offers.

8. Provide RIC SSC with a refurbished BRV VOR.
