Basic-Fit Headquarter’s Wasquehal

Basic-Fit relocated its headquarters to Wasquehal, France, setting up operations in a newly renovated, 3.000 m² multi-storey office building that includes a gym facility on the ground floor.

While the building was designed to offer modern, collaborative workspaces across two upper levels, an acoustic study conducted by Orféa revealed a significant risk of noise and vibration transmission from the free weight area to the offices above.

Such projects come with added challenges, particularly when a gym is part of the design, as gym activities generate high-intensity impact noise and vibrations at low frequencies, which are notoriously difficult to isolate in lightweight constructions like Cross-Laminated Timber (CLT).

To address the acoustic challenges of this CLT building, particularly the transmission of low-frequency vibrations from the gym to the office spaces above, an in-situ impact test was carried out by acoustic consultant. Using a 30 kg dumbbell dropped from thigh height on a Stravigym XP with GympactLayer-45 and dBooster® technology system with a 20 mm finishing tile, the test showed that emergence levels remained within the admissible limits across the frequency spectrum, in compliance with French Decree No. 2006-1099, as well as the stricter limits set by the acoustician for lower frequency ranges - exceeding regulatory requirements.

Based on these results, the Stravigym XP system, combined with Stravigym GympactLayer-45 and dBooster® technology, was selected and installed across the 412 m² free weight zone.

This lightweight, high-performance floating floor was ideally suited to the nature of the CLT construction, offering effective isolation of heavy impacts without adding significant mass to the structure.

One of the key advantages of this solution was its efficient installation process, the entire system was delivered and installed within one week, ensuring the project stayed on schedule.

The result is a fully functional, acoustically treated gym that supports a high-quality training experience while maintaining quiet and comfort in the offices above.
