Bristol HQ Case Study Study When a large Government headquarters, located in Bristol, required an urgent remediation of its ductwork systems, industry-leading ventilation-cleaning specialists, Ventilation Surveys and Services Ltd, was quick to provide the essential, on-site help needed. Eight fire crews were called to the premises after a fire broke out within the walls of the building and smoke was observed coming from the roof of the five-storey office. A fire was located in a courtyard area in the centre of the building, which had started in a waterproof membrane within the walls of the building, causing smoke to quickly rise up inside, affecting all five floors. Fortunately, no-one was injured during the incident, and VSS Chief Executive Officer, Nick Umfreville, was able to get to work quickly, with a site visit arranged the following day. The remedial decontamination quotation was completed on site and emailed by midday that day to the client. The necessary next steps were sanctioned at 5.30pm the same afternoon by the client, by which time a multi-disciplined team had been assembled from all across the UK. This team converged on Bristol at 7.30am the following day, and two 12-hour shifts were worked under direct supervision of the Director all weekend. Due to environmentally sensitive issues revolving around Departmental policy, no chemicals were permitted to be used in what was a fire-restoration project, where normally de-smoking and chlorine dioxide fogging would have resulted in the neutralisation of the smoke molecules which affect the noses of occupants. Instead, continuous cold water pressurised-washing and rinsing of the systems was adopted. Next, deliberate aeration of the structure using the building’s revolutionary natural and mechanically enhanced ventilation systems were brought into play thus producing the same result without the use of chemicals at all. Finally, a mass-supply air purge and non-return procedure was carried out, orchestrated by the project team using all the fans at once to create a globalised purge action prior to re-occupation. The £10 million Government office block is one of Britain’s greenest buildings, and thanks to VSS, the building was fit for occupation the following Monday, with recommendations to regularly inspect all aspects of the building’s Fire Protocols, including fire-damper inspections, ventilation compliance, alarm dry runs, sensor stress testing and internal detector-challenging. “These checks are regular features of our revolutionary Client Compliance Software –Intellivents”, said Nick Umfreville. “This software is free to our Clients and runs on a server/client login platform. We were happy to bring this building’s compliance back into focus, where it will remain now as one of our adopted Clients on our Maintenance Register.” For more information on ventilation risk assessments, visit or contact us directly on 0333 500 8368 (local rate).
