Project description

As part of the transformation of the AMAG garage at Petit-Lancy, the old VW and Porsche garages were completely demolished and a new building has been built in their place.

BG was appointed to undertake a diagnostic survey of the pollution intrinsic to the old buildings (e.g. asbestos) to enable them to develop the tender documentation for the remediation and demolition as well as the site waste management lots. After managing the tender process, BG organised and monitored the remediation, demolition, earthworks and site waste management packages on site.
