We do a lot of healthcare work and often have lights and other booms that require extensive structural support above the ceiling. That said we have never had a specification section for this work. It is usually supporting equipment that is OFCI and the GC has never failed to provide adaquate support, but I am thinking there must be a better way to handle this. How specific should a section be (assuming it's needed) in describing how to support the equipment. What else is important to include? |

The materials and products that the supprot assemblies are made of can easily be addressed in Division 5 and Division 9. We do work for one of the national research laboratories. A current project for one of those includes a Division One Section provided by the Laboratory, "Section 01 35 23 - Lateral Force Provisions" which specifies "Criteria for the design and construction of lateral force anchorage for non-structural components of the Project, including..." Bear in mind this is a project located in an active seismic zone (Berkeley, CA). If you feel the need to tie things together with a dedicated Specification Section, something like that adapted to include all loads might be the way to go. |

It should also be noted just what is being supported and to specify if vibration is a potential issue. If you are doing laser surgery a little shimmy can be a very bad thing. Depending on where the supports are located and what they are holding we typically have our structural engineer do actual contract drawings designed to accommodate the owner supplied equipment. Of course this means that the equipment must be picked in advance and it can not be changed (not without an extra anyway) |

Whether it's slotted channel framing or structural supports, we have a structural engineer responsible for the design, either ours or the manufacturer's / contractor's. Vibration tolerances can be critical in any type of surgery or laboratory. |

In my former firm, the structural engineer prepared a sheet of details for hanging methods. It included member sizes, attachment points and details, load criteria, etc. Each trade had to hang their systems using one of these design details as determined by the conditions encountered for each situation. It seemed to work very well. |
