Oreston Fire Safety Works
One of the key challenges within our estate is ensuring that older buildings comply with modern building regulations. Oreston School, originally built in 1880, is a prime example. Over its 140-year history, the school has undergone numerous extensions and refurbishments. However, earlier works to provide office and teaching spaces on the first and second floors were not completed according to approved plans.
The most pressing issue was the lack of a compliant fire escape route. According to current regulations, the upper two floors should have a fire-sterile escape route that leads directly outside. Unfortunately, this vital corridor was omitted, leaving staff and students with a greater risk of passing through a fire to exit the building, a situation that falls short of modern safety standards.
To address this, a team was assembled, including the Central Estates team, fire engineers (who also served as expert witnesses in the Grenfell inquiry), a surveying practice, structural engineers, and building contractors. Together, they designed a solution acceptable to both the Fire Service and the Building Control Authority. This involved extensive works to contain potential fire spread and creating an alternative escape route via a new second staircase. As with many complex projects, the design phase took longer than the practical works.
Executing this project was challenging due to the building's unknown structural issues, only discovered once walls, doors, and floors were opened up. Given that Oreston is a working school, a phased plan was implemented. Major structural works, including the new staircase, were scheduled during the summer break, with smaller, less disruptive tasks planned for term times.
To expedite the project, demolition and preparatory works began before the end of the summer term. By the start of autumn, critical safety upgrades were completed, including fire compartmentation, an extended fire alarm system, new fire doors, and the installation of the second staircase.
Final touches are scheduled for the upcoming half-term, but the safety of the building has already been significantly enhanced. We are eagerly anticipating an interim visit from the Fire Service in early October.
