Extractor Fan Replacements in Car Park

Our customers site has a basement carpark that has vehicle parking facilities and also house’s the site generator. The site being on top of a main line tube & train station has very limited options for installing new building services equipment and as such when the generator was installed the exhaust expels into the basement car park and the existing car park ventilation system removed the generator exhaust fumes to roof level.

The fans are a twin, duty & standby system but one of the fans had failed leaving the customer at risk. The project was to replace the failed fan, switch the systems over and replace the working fan for a new motor to ensure future service.

Access is very poor and large section of the extract ductwork had to be removed to provide safe access to the failed motors. Also motors had to be ATEX rated due to the air being extracted from the car park. Once complete the fans were re-balanced and all seals on the ductwork replaced.

1. No redundancy for car park extract system.
2. If the only working fan failed unable to run generator
3. Access to fans very restrictive
4. Enclosed space so teams needed to be specially trained for an emergency situation

Added resilience for the client’s tenants in the event of a power failure. Also added life expectancy for the extract system.

Asset Building Services have extensive knowledge of all building services systems and have the specialist teams to work in any environment so was the logical choice for our customer.
