Fire strategy reporting for UK projects
Fire Strategy for UK Building Projects
A fire strategy report that sets out the fire-safety basis of the design for a specific project: the assumptions, the design route agreed for the applicable jurisdiction, and the provisions the design team and dutyholders need to carry through. It supports design development and regulatory review; it does not grant or guarantee approval.
New build project requiring a fire-safety design basis
Computational modelling of smoke movement, tenability and occupant evacuation for a specific building and a specific design question, delivered as a written technical report with the inputs, assumptions, sensitivity cases and limitations recorded. It supports design development and regulatory review; it does not grant or guarantee approval.
Atria, basements, large-volume or connected spaces
Extended travel distances or a non-standard escape strategy
A decision between natural and mechanical smoke ventilation
A fire risk assessment for the building, its use and its jurisdiction, delivered as a written report with significant findings, prioritised actions and recorded limitations. The assessment method and inspection scope are agreed in writing before work begins.
Annual review or change in building use
New responsible person or landlord transition
Fire door, compartmentation or evacuation concerns
Written fire safety management arrangements for a specific building or estate: who holds which duty, what is checked and how often, what evidence is kept, and how defects escalate. The output supports the Responsible Person and other dutyholders; it does not transfer or discharge their legal duties.
Complex occupancy with multiple tenants, departments or managing agents
A written fire safety policy exists but is not followed consistently
Passive protection defects or unclear fire-stopping records
A written route map of the fire-safety obligations that apply to a specific project or building: the applicable duties for the relevant jurisdiction, the evidence each one requires, who owns that evidence and where the gaps currently are. This is technical fire-safety consultancy, not legal advice and not a regulatory determination.
A building or project may be a higher-risk building and the position needs confirming
Planning, building control or regulator comments raise fire-safety obligations
Safety case, golden thread or dutyholder responsibilities are unclear
Fire-safety evidence support for HRB building control
Gateway 2 Building Control Support for Higher-Risk Buildings
We review and coordinate the fire-safety evidence for a higher-risk building control application in England within an agreed scope: what exists, what is missing, what the assumptions are and where the interfaces sit. The Building Safety Regulator decides the application; we do not.
A higher-risk building project in England approaching a building control approval application
Fire-safety design information spread across drawings, reports and specifications with no single evidence view
Uncertainty about whether the project or the specific work falls inside the higher-risk regime
Retrospective Fire Strategy for Existing Buildings
A retrospective fire strategy records the fire-safety arrangements observed and evidenced in an existing building, the assumptions that cannot yet be confirmed, and the further work needed to establish a usable design basis.
Scoped fire-engineering input to the safety case and safety case report, including fire-risk evidence, control measures, gaps and interfaces with structural-safety evidence.
Safety case evidence is fragmented
Fire and structural interfaces are unclear
The safety case report needs a fire-engineering contribution
A scoped fire risk appraisal of external walls based on the records, investigation evidence and building context available, with uncertainties and further investigation needs stated.
Magnus Opifex Seven provides consultancy for building water services, drainage and pipework coordination. We help architects, developers, building owners and project teams define requirements, review design information and resolve interfaces with the wider building design.
Design information for water or drainage needs an independent review
Risers, plant space or pipe routes conflict with other disciplines
An existing building's water services or drainage need assessing before alterations
The enquiry is scoped from the facts you can provide.
A useful quotation depends on the building information, the jurisdiction, the current project stage and the specific question the report has to answer. The written scope records what is included and what is not.
01
Send current drawings, sections and any fire strategy or fire risk assessment already held.
02
Confirm building use, occupancy, jurisdiction, project stage and the reason for the enquiry.
03
Include reviewer, insurer, landlord or regulator comments where they define the question to answer.
04
We confirm a written scope, deliverable limits and quotation before work starts.
05
Where information is missing, the limitation is recorded rather than assumed.
