Safety strategies
Verification process Arup is currently involved with verifying the fire safety measures being constructed on a number of major new stations against the original design intent information. Based on our experience, it is our view that the building industry in this country could look to these infrastructure project examples and implement similar processes and procedures for all types of buildings, beyond just stations. Main contractors working on underground
stations are expected to be self assuring and are required to provide evidence that what they have built and installed is in accordance with the approved fire strategy design. The necessary evidence of this compliance is recorded in a Fire Safety Compliance Inspection Report which is compiled by a fire engineer working on behalf of the contractor. For example, the process currently used on Crossrail projects is illustrated below. The fire engineer working on behalf of the
contractor is responsible for the verification of both passive and active fire safety systems installed. This process can simply be illustrated as being a three step process: 1. Verification of the design. 2. Verification of the installation as it progresses on site.
3. Verification/testing of the completed installations.
This process requires a team of fire engineers and specialists to be based on site while the construction works and commissioning of systems is being undertaken. It provides the assurance and confidence to the client and
all stakeholders that the fire safety installations are fully verified, fit for purpose and in accordance with the approved fire strategy. In following this process, it can be ensured
that new stations will be handed over to the client for operation, with documentary evidence of them being safe to occupy and operate – something that has been sadly lacking in many construction projects, particularly building projects, in this country.
The future
This is a time when enormous change is happening in how we create buildings in the UK. The Grenfell Tower Public Inquiry is ongoing and the recommendations of the Independent Review of Building Regulations and Fire Safety: Final Report by Dame Judith Hackitt are still being developed into tangible solutions. The suggestions we are making here and implementing now in our work are intended to help with that process and to show that by treating fire safety as a positive design aspect rather than a disruptor, change for the good is possible. We all aim to create safe buildings and the suggestions we make here should help make that become a reality; and it places more onus and responsibility on the fire safety engineer to lead in making this happen
