Our work on major infrastructure, mixed and residential developments includes noise and vibration surveys on site, noise reports for planning, production of noise chapters for environmental statements and expert witness services at planning inquiries. We provide advice on the planning of sites to control noise and vibration. We advise on the acoustic design of individual buildings, including the sound insulation of the building envelope, taking into consideration preferences for natural ventilation, the sound insulation of separating walls and separating floors and the need for acoustic treatment of spaces. We undertake acoustic inspections during construction and commissioning tests at the end of the construction stage, which include sound insulation pre-completion tests (Building Regulations Part E and Code for Sustainable Homes) and domestic airtightness testing (Building Regulations Part L).
