FAQ

  • “My Acoustical Consultant selected LSM for use on my project, what is the first step?”

    Contacting your Local Representative is a good place to start. You may find the Design Phase Timeline helpful as an overview of typical activities.

  • “What information is included in your shop drawings?”

    Our shop drawings include coordination of the live and dead loads, a dimensioned isolator layout with capacities, acoustical information including loading of individual isolators (with deflection curves), as well as project specific and general installation guidelines for the contractors.

  • “What information is needed for Kinetics to create shop drawings?”

    The timely gathering of essential information makes a difference in our turnaround time. A guide for helpful information can be found here.

  • “Should isolated floor drawings be in the Structural or Architectural plans?”

    As isolated slabs are by their nature non-structural, they typically reside in the Architectural Plans.

  • “What structural concerns are there?”

    Ensure that the structural slab has the proper depression to include the isolated slab as well as the airspace created after the slab is lifted. Structural slab stiffness and capacity considerations must be made relative to the activity of the floor (e.g. if the floor activity is to include the drop of heavy, a stiffer structural slab is required). The existing floor should be flat as the isolators can only mirror the floor on which they are resting. If there are seismic concerns, designing a curb capable of restraining the isolated slab will eliminate the cost of using in-slab restraints.

  • “Who should design the rebar spacing in the isolated slab?”

    If your project isn’t employing a structural engineer of record, then slab design should go to an independent third party firm to avoid any potential conflict-of-interest with isolator layout. Kinetics maintains relationships with independent structural engineering firms experienced in isolated slab design who can seal the reinforcement design in all fifty states.

  • “Help! The contractor just finished raising the floor and it is sticking up past the surrounding elevation!”

    Kinetics selects spring capacities and isolator spacing based on many factors, including but not limited to, even deflection between adjacent isolators, (limits concrete slab stress) the type of activity that will be occurring on the isolated slab, as well as the total live and dead loads that will be on the slab. In some cases the slab may need to be raised above the room threshold, but will settle to proper height once all the loads are added.
