A Fire Statement is a planning document, not a fire strategy. Here is what each section has to settle, and what can honestly be left to Gateway Two.
Fire statement and design and access statement together
On a relevant building you submit both a Fire Statement and a Design and Access Statement. They describe the same cores, the same access route and the same facade. Here is how to coordinate them.
Dangerous structures and emergency works in a conservation area
A structural engineer saying the wall is dangerous is not consent to demolish it. The urgent works defence is narrow and the record you keep decides everything.
Mineral safeguarding areas and former non-coal workings
There is no Coal Authority for limestone, gypsum or brine. On a site over former non-coal workings the investigation and the liability sit with you.
Sprinkler tanks and pump rooms: the space they need
A suppression system needs a tank, two pumps and a room to put them in. Decide where that space goes before the accommodation schedule is fixed, not after.
Firefighting water supply on a rural site
Rural schemes stall on firefighting water more often than on anything else in the fire consultee response. Here is what the flow rates require and what a static source has to deliver.
Replacing cladding on a consented but unbuilt scheme
A facade substitution on a consented scheme engages the materials condition, the fire statement and the building control route. How to pick the route and sequence the approvals.
Fire safety information at the point of occupation
Regulation 38 information, the fire risk assessment duty and the 2022 regulations all bite from occupation. What the handover package contains and how to check it before exchange.
Structural movement and subsidence on a development site
Subsidence rarely stops a permission, but it changes the documents and sometimes the scheme. How soil, trees and foundations interact, and the evidence a council will condition.
Fire engineering a building with a single access road
One route in means the fire service will ask what happens when it is blocked. Appliance dimensions, secondary access options and compensating measures in the building.
Removing internal walls in a listed building
Listing covers the inside of a building, and plan form is often the part that matters most. The structural case and the heritage case have to agree with each other.
Temporary works and the planning permission boundary
Planning permission authorises the development, not the scaffold over the footway or the crane jib over a neighbour's roof. Those come from the Highways Act and private agreements.
Fire and structural evidence for a basement storey
A basement has no ground level window to climb out of, and digging beneath a house removes the support its foundations rely on. Those two facts drive every requirement.
Upward extension: structural adequacy of the host building
Lightweight construction reduces added dead load and does nothing for overturning. Investigate stability first, then vertical capacity, then foundations, because that is the order of difficulty.
Fire statement content: the plans and the narrative
A Gateway One fire statement answers what planning can determine: layout, appliance access, water supply, the escape strategy in principle and the construction phase. The detailed design belongs at Gateway Two.
Piling risk assessments and when a council requires one
Piling can drive a pathway through the layer protecting an aquifer, which is why permissions carry a piling condition. The mechanism, the method hierarchy and how to discharge it on time.
Geotechnical assessment at planning application stage
At application stage the authority wants feasibility and risk, not foundation design. The desk study sources, the investigation phasing that keeps cost down, and the conditions to expect.
Retain or demolish: the evidence authorities now expect
Authorities increasingly test whether an existing building could be retained before accepting demolition. The structural investigation, the height and floorplate limits, and the options appraisal that persuades.
Ground movement assessment and the party wall interface
Planning permission does not give you a right to underpin a neighbour's wall. The movement assessment and the party wall award answer different questions, and you need both.
The hydrogeology section of a basement impact assessment
Basement hydrogeology sections fail on monitoring duration more than on technique. Here is what to establish, how long to monitor and what auditors look for.
Fire statement for a change of use rather than new build
Article 9A ties the fire statement duty to the finished building, so a tall office to residential conversion engages Planning Gateway One. The hard part is proving what the existing construction is.
Evacuation lifts and what planning can actually secure
An evacuation lift changes the core, the floor plate and the unit mix, so it is a planning-stage decision. What a condition can secure is narrower than applicants assume.
Fire appliance access on a cul-de-sac housing layout
Fire access is decided by the road layout, long before building control consults the fire service. On a cul-de-sac the turning head and the hose run are where schemes fail.
Means of escape and layout at planning stage
A 7.5m dead end limit decides how many flats a core can serve. Get the fire logic into the floor plate before the application, not after permission.
