Figure 91 shows the vibration isolation curb attached to a structure. The vibration isolation curb may be a continuously supported type as shown in Figure 91 or a point loaded frame.

Step 1: Attach curb or post and beam with equipment support frame to building structure

Step 2: Install flashing

Install flashing for a continuously supported curb as shown in Figure 86 or flash the stanchions as shown in Figure 84.

Step 3: Attach vibration isolation curb to structure

Figure 88 shows options used to attach curb to structure.

Use contract documents for flashing details.

Step 4: Attach equipment to the vibration isolation curb

Figure 91 & 92 show various seismic attachment methods used to attach equipment to a vibration isolation curb.
