Beside an operational railway, groundborne vibration often drives the design more than sound levels do. The two effects need separate measurement, separate criteria and separate mitigation.
Road traffic noise assessment for a new housing site
Layout does more for road traffic noise than glazing ever will. Establishing the traffic case, calculating facade levels and presenting results an officer can check.
Planning control and licensing control of venue noise
A premises licence until 1am does not override a planning condition closing you at 11pm. How the two noise regimes differ, and how to align them with evidence.
Designing dark corridors for bats around a development
Bat commuting routes need continuous darkness, not a lower average lux. How to set the corridor, choose and aim luminaires, and prove the result on an isolux plot.
Curfew hours and part night lighting conditions
Obtrusive light guidance sets tighter limits after a curfew hour, which is why conditions use them. Here is how to specify the hours, the controls and the verification that makes a condition work.
Extract termination height and odour control selection
Most kitchen extraction refusals come down to a flue that stops below the ridge or abatement that does not match the cooking. Here is how to specify both and what evidence a council expects.
Odour assessment and the FIDOL factors
Odour in planning is judged on five characteristics rather than on strength alone. Here is what each of the FIDOL factors means, how field assessment and modelling are used, and what a workable condition looks like.
Nitrogen dioxide diffusion tube surveys for planning
The annual mean objective for nitrogen dioxide is 40 micrograms per cubic metre, and a six week survey cannot be compared with it. Duration, bias adjustment and honest uncertainty decide whether the data is usable.
Plant noise from commercial kitchens: assessment and fixes
Kitchen plant noise is assessed under BS 4142 by comparing the rating level with measured background. Character corrections for tonality and cycling often decide the case.
Scoping noise, air and odour work at pre-application
Environmental health is an internal consultee with outsized influence on noise, air and odour cases. A written pre-application scope tells you what to commission and what to leave out.
Light spill onto neighbouring windows from a car park
Spill onto a window is vertical illuminance in lux, tested against zone limits that tighten after curfew. Here is how to design and condition for the tighter case.
Air quality and odour evidence for a crematorium
Cremators are a permitted process; planning controls the stack, the plant footprint and the dispersion outcome. Here is how to evidence the planning half properly.
Assessing odour from agricultural buildings near homes
Livestock odour applications fail on the source nobody mitigated. Here is how to identify every source, choose the right level of assessment and mitigate credibly.
Cumulative assessment where several plant items are proposed
Assess plant item by item and the total is understated. Here is how to combine sound power levels, choose the worst case period and specify attenuation that works.
Noise limits in section 106 and planning conditions
An enforceable noise condition states a limit, a position, a period and a method. Here is how to draft one, how to verify it and how a limit gets varied later.
Acoustic design statements and what they add
Numbers show whether internal levels are met. A design statement shows whether they were met by designing properly or by sealing the windows, which is what an officer wants to know.
Responding to an environmental health holding objection
Environmental health objections are cleared by diagnosis before drafting. Missing data needs data, a method dispute needs justification, and an objection in principle needs a planning answer.
Air quality assessment for a car park or servicing yard
Parking and servicing areas are assessed at a local scale: cold start emissions, idling at barriers and where the ventilation discharge goes relative to the nearest window.
Odour and noise conditions for a micro-brewery
Boil odour, glycol chillers and the taproom nobody declared are what sink small brewery applications. How to handle each separately and avoid a condition that caps your output.
Railway vibration and residential layout decisions
Ground-borne vibration and re-radiated noise from a railway are unaffected by facade insulation. How to measure the baseline before the masterplan, and why distance beats isolation bearings every time.
Entertainment noise and sound limiters as a condition
A sound limiter set on a poorly insulated building just makes the venue unviable. How amplified music is assessed in the low frequency bands, how a limiter is set, and what the three standard conditions do.
Noise from outdoor seating and beer gardens
Patron noise sits outside the standard most acousticians use, so an external seating case is won on context, hours, layout and a management plan an officer can check. Here is how to build one.
Dust assessment for demolition and earthworks
Construction dust is assessed by risk category, not by modelled concentration. The value of the work is the mitigation schedule it produces, activity by activity.
Odour risk assessment for a waste or composting facility
Planning decides whether the location is right; the permit decides how emissions are controlled. Screen on separation distance, characterise sources honestly, then model only if the answer is still unclear.
