Goodlife Canada Noise Structural Vibration

Location: Across Canada
Owner/Operators: Goodlife FitnessNortham Realty (of Bell Trinity Square building)


Goodlife Fitness is the largest health club company in Canada with 275 outlets across the country. The clubs offers up-to-date cardio equipment, group cycling studios, cardio theatres, lounges, along with personal training and Group Exercise classes.

We have worked with the company directly as a customer and indirectly via a real estate management company as part of a lease negotiation.

In the direct instances, Goodlife Fitness engaged HGC Engineering to create scenarios in order to assess the potential for sound and vibration intrusion from typical activities of proposed GoodLife Fitness clubs into adjacent tenant spaces in buildings where the clubs, across Canada, co-located with others. Indirectly, but under the same circumstances, we were engaged by Northam Realty, a real estate investment group to investigate the noise and vibration impact of a Goodlife Fitness Centre potentially opening in the Bell Trinity Square, a downtown Toronto office building.

In both scenarios, once the analysis was completed, we provided mitigation design recommendations for incorporation into the lease agreement to ensure that noise and vibration would not, under practical circumstances, intrude on other spaces.

Using the rhythm, amplitude, and frequency content characteristics of a typical “body pump” class at an existing location, including the music program played during the exercise routines, we recreated those same characteristics in the proposed spaces using an audio PA system.

Similar conditions were created in current fit-outs of spaces proposed to be the aerobics room, and weights/treadmill areas.

With regards to vibration caused by aerobic activity or structurally-transmitted noise from vibration impacts in the weights and treadmill areas, our previous analysis was used to indicate the requirements for floor slab stiffness to mitigate perceptible vibration in adjacent spaces.

The potential for audible structure-borne noise from these type of activities can be difficult to predict, therefore, best practices for flooring systems were recommended.  This entails an appropriate resilient underlay below a subfloor (usually wood, but sometimes concrete is required), upon which the surface flooring of choice may be used (usually sports rubber flooring).  This technique has proven to be very effective in isolating fitness spaces in buildings with “sensitive” tenant neighbours.
