Contact Information: Joseph Corliss 12300 Twinbrook Pky-Suite 600C Rockville, MD 20852 301-443-4205 jcorliss@hqe.ihs.com Activity: Structural Keyword: Plywood Flooring CSO No.:06150 Background: Standard plywood subflooring placed on wood joist at 400 and 600 mm spans; no other special details or specifications were required by the contract. Essentially this is a residential standard subfloor and exhibits deflection and a squeaking noise when walked on. Lessons Learned: A commercial floor must be specified to handle the traffic in a Health Center, especially in the public areas. Recommended Action: If a plywood floor is used in a Health Center, it should be detailed with two layers (structural and leveling subfloor), non-overlapping joints or joint support between joists and fastened with glue and screws.
