BB7 were asked to deliver a comprehensive fire strategy and engineering solutions for Waterloo Station, London.
Situated in the centre of London Borough of Lambeth, London Waterloo station is a central London railway terminus and London underground station complex. The station features 41 retail units over ground and first floor and the remaining three floors is made up of offices. It is estimated that the general office building located within Waterloo Station was constructed between 1910 and 1919. The Waterloo general office refurbishment affected five floors.
The BB7 response
Initially, BB7 were asked to carry out an occupancy assessment to determine the maximum
feasible occupancy achievable, including an assessment to determine the suitability of the
fire time of the structure with respect to the escape time and number of occupants. Following on from the occupancy assessment, BB7 were also commissioned to develop a bespoke fire strategy for the refurbishment of the general offices as well as an interim fire safety strategy during the office decant operation over a temporary period.
Following on from this, BB7 were appointed to carry out a non-intrusive survey to review the current conditions of the building structure with respect to its fire resistance. During the survey, it was found there are two main types of the floor structure that have historical features and likely to be from the original design dated back 100 years ago. There was limited documented evidence on the floor structure and performance and so BB7 were tasked with assessing the fire performance of the floor structure and recommending remedial works to fulfil the fire requirements of the
Benefits of service
The client’s aspirations were to maximise the potential office space and to allow an increased level of occupation whilst minimising the impact on the principle fire safety provisions. BB7 were able to facilitate this with a new agreed fire strategy with only some small changes to the existing design with minimal cost implications.Let's work together
