Bolton HallBuilding #1983
3210 N. Maryland Avenue
Renovation: 1998 (limited)
Space: 153,085 gsf
Eight stories plus basement and penthouse
- Building-wide WALMS survey performed February 2007.
- All original thermal system insulation (TSI) should be regarded as asbestos containing material (ACM). Straight sections are fiberglass with mudded ACM fittings. All new insulation is Armaflex or is characteristic of plastic covered fiberglass fittings and fiberglass straight sections. Please use caution when removing ceiling tiles; damaged fittings are often encountered, particularly adjacent to booster coils and valves.
- Acoustical ACM plaster exists in room 150.
- Most interior walls are wallboard over metal studs, spackling compound has not been sampled. Plaster sampled to date has been negative for ACM.
- Original fire-rated doors have an asbestos-core.
- All original nine inch floor tile should be regarded as vinyl asbestos tile (VAT), and all black mastic as ACM. Twelve inch tile may or may not be VAT; please sample before any disturbance. Floor tile was removed from the first and fourth floors and several basement and second floor rooms during the 1998 renovation, but all ACM mastic was left in place.
- There are a variety of ceiling tile in this building; to-date, all samples have been negative. Please request inspection for non-uniform/non-characteristic tiles.
- Fire-stop packing in decking core penetrations is ACM.
- Spray-on decking insulation exists in the space above the tower's soffit
Spray-on decking insulation still exists above the HVAC ductwork in room 140; see EHSRM for exact locations. All other spray-on removed from 140 and 100F during the 1998 partial building renovation.

- Floor 3 Soffit Spray-on Location

- Original rubberized / plasticized insulation on electrical wiring is non-friable ACM.
- Contact Physical Plant Services for documentation of past abatement during renovation projects.
- Please see the UWM Asbestos Inventory
Other Environmental / Safety Issues:
- EMF: Radio frequency (RF) exposure analysis for the roof-mounted Cellular and PCS radio antennas is documented in the report Radio Frequency Energy Analysis-Bolton Hall, Project No. PL-00KK, prepared by Phasor Labs, August 2000. As stated in the report: "Areas behind the antennas and within the equipment rooms have no concern with RF energy. Areas below the roof have no concern with RF energy." In other words, radio frequency exposure is far below hygienic and regulatory standards in these areas. All access and work on the Bolton roof must be coordinated with UWM Physical Plant Services. Workers must stay within the enclosure; access in front of the transmitters (i.e., outside the enclosure) is not permitted. Access beyond the roof enclosure (i.e., the regulated area) must be coordinated with the cellular phone companies.
For additional information on radiofrequency electromagnetic energy, see "Radio Frequency Safety", from the Federal Communications Commission Office of Engineering and Technology.
- Fall Protection/Prevention: Under development.
- Fire Protection: Bolton Hall is not sprinklered. The nearest fire hydrants are located (must be determined).
- HVAC: Ventilation Systems (under development):
AC3, Room 350 (east unit)
AC4, Room 350 (west unit)
ACU6, Room 350 (south unit)
- USTs: There are no known underground storage tanks associated with Bolton Hall. The two elevators are hoist elevators.
