Utility Gravity Supports and Attachments

With the adoption of the IBC, whenever seismic bracing is required on a project the primary supports for the utilities must also be engineered (ASCE 7-05 13.2.6).  ISAT’s Engineering Services can provide custom engineering packages for primary vertical support of suspended or floor mounted utilities.  Base packages include calculations and details, broken down by utility size, providing all necessary information to support your systems.  For each utility ISAT will specify support spacing, rod size, design dead and seismic loads, and multiple anchorage options (from concrete inserts to expansion anchors to beam clamps).  ISAT’s vertical support packages can also include calculations and details for supplemental steel where connection to the overhead substrate (i.e. roof deck) is prohibited.  Whether the primary anchorage substrate for the project is concrete, steel or wood, leave the guesswork behind and let ISAT’s engineering staff provide the solutions to your vertical support problems!
