Maintain soffits under portions of buildings, canopies, or overhanging wings
which extend over truck and public bus traffic areas at a height which will
provide 4.2 m (14 ft.) minimum head room. Maintain a grade either side of the
passageway to provide the required head room for the longest wheel base
trailer permitted by the state.
3.2.6 MAINTENANCE-SHOP ENTRANCE PLATFORMS
Entrance platforms to maintenance shop floors shall be 150 mm (6 in.) high
above grade, at same level as shop floors, and shall be a minimum of 3 m (10
ft.) wide. Slope platform away from the building. Provide double doors at
platforms to permit direct transfer of long lengths of pipe, lumber, etc. to
maintenance shop storage areas.

3.2.7.1 All platforms, ramps and stairs adjacent to entrances shall have
non-slip surfaces.
3.2.7.2 All entrances listed in paragraph 3.2.2 and all exits at grade shall

3.3.1 BUILDING ACCESS AND EGRESS DOORS (EXTERIOR)
3.3.1.1 ELECTROMAGNETIC LOCKING SYSTEM
3.3.1.1.1 GENERAL
When requested by the medical center, equip all building access and egress
doors (pedestrian) with centrally controlled, listed locking devices, i.e. an

exit through a door equipped with an electromagnetic locking system.
3.3.1.1.3 DESIGN BY SECURITY CONSULTANT
The A/E shall obtain the services of a security consultant to design the exit
door locking system. The consultant shall coordinate the design with the
station security officials, especially where an existing system is in place,
to attempt to achieve compatibility.

If a centrally controlled electromagnetic locking system is not used, provide
exterior door locks that are controlled by key on the outside but allow
egress from inside by turning a lever handle or depressing a panic bar.
