Seismic, Vibration and Fire Safety Engineering

Acrefine’s engineering practice covers the ways a building and the systems inside it can fail — under an earthquake, under continuous vibration from the ground, under fire and smoke, and under the loss of the services that keep the building running. Some of that work is a calculation on a single piece of plant; some of it is a modelling exercise across a whole facility.

Six lines of work

Building risk engineering, from the equipment up.

Seismic Calculations for Equipment | Seismic Load AnalysisSeismic load calculations and analysis for MEP and HVAC equipment, to ASCE 7, IBC and the code that applies on your project. Produced as submittal-ready documentation for equipment approval, with overturning calculations, equipment analysis and shake-table certification routes covered.See the service
Seismic Bracing DesignBracing and restraint design for piping, ductwork, cable trays and MEP plant, so building services stay in place and transfer seismic force safely into the structure. Includes the judgement call on what does not need bracing — an over-braced system costs money and solves nothing.See the service
Noise and Vibration ControlApplied vibration isolation engineering for chillers, pumps, fans, air handling units, and the plant rooms that house them, sized to the criterion the project has to meet. Our longest-established line of work, and the one most often called in after complaints have already started.See the service
Fire Safety EngineeringPerformance-based fire safety engineering: CFD fire and smoke modelling, sprinkler and passive protection design, means of escape, fire risk assessment and fire strategy. Delivered as the analysis and evidence a building control or Gateway 2 submission has to stand on.See the service
Base Isolation for Buildings: Seismic and VibrationBase isolation for buildings, for two different reasons: earthquake protection where the seismic hazard requires it, and vibration isolation where a railway, a metro line or industrial plant next door does. Covers isolation engineering, assessment of existing buildings and independent peer review.See the service
Data Centre Safety EngineeringFire, smoke, battery, water and seismic risk engineering for mission critical facilities where an incident is measured in downtime rather than damage. Each carries its own failure path to the same outage. Written for operators, insurers and design teams who need the continuity secured.See the service

The work here is delivered for design teams, contractors, developers and owners, in the UK and Ireland and across the wider EMEA region. If you are not sure which of these your problem belongs to, that is a normal starting point — describe the building and we will tell you.

Describe the building and what you are trying to prevent.

We will determine which of these applies — and if none of them does, we will tell you so.
