10-5.4.1
Installation Practice. Large diameter piping is supported above the floor
by small concrete piers. Small diameter piping is generally hung from ceilings or walls
by a variety of suitable pipe hangers or brackets. An alternate method of installing small
diameter piping is to run the pipes along racks that are attached to masonry walls by
expansion bolts or structural steel. In areas subject to earthquakes, the brackets and
connections must be capable of resisting seismic forces.
10-5.4.2
Installation Timing. Because of the character of mechanical or piping
installation, and general lack of sufficient working space to improve efficiency, the
mechanical work should be done after the structural work has been nearly completed.
This phase is particularly applicable when separate contracts are let for structural and
mechanical work.
