Project Experience Across Yorkshire

Three examples of the kind of work we handle regularly. Project details are described in general terms to protect client confidentiality. The challenges, approaches and outcomes reflect genuine experience.

Planning & Noise Assessment 01

Planning Noise Assessment — Residential Conversion, West Yorkshire

Client type
Developer / planning applicant
Service
Noise impact assessment for full planning application
Project type
Change of use — former commercial building to 14 residential apartments
Location
West Yorkshire town centre

Background

A developer had acquired a redundant commercial building in a West Yorkshire town centre and was seeking full planning permission to convert it into 14 apartments. The site sat on one side adjacent to a busy classified road with significant day and night traffic, and on another side close to a commercial yard in active evening use.

The local planning authority had formally requested an acoustic report as part of the application, citing the mixed noise environment and the proximity of several proposed bedrooms to the road-facing facade. The developer had a firm submission deadline and needed a technically sound assessment that was structured correctly for the relevant local authority.

Our Approach

Following an initial site visit to assess the noise environment and identify the critical elevations, unattended monitoring equipment was deployed at the site boundary. Monitoring ran continuously over 72 hours, covering weekday and weekend periods including the night-time window relevant for residential development.

The data was analysed against the internal noise criteria required by current planning guidance, with particular focus on the bedroom locations on the road-facing elevation. The existing glazing specification was found to be insufficient for those rooms, and a revised facade specification was developed as part of the assessment.

The noise impact assessment report was issued in draft to the developer's architect for comment before being finalised for planning submission.

Outcome

Planning permission was granted at the first application. No acoustic objections were raised by the environmental health consultee and no additional information was requested during the determination period.

The acoustic planning condition attached to the permission required implementation of the facade specification, which had already been incorporated into the architect's drawings as part of the design process. The developer moved to the next project stage on programme.

"The report was structured and referenced exactly as the planning authority required. Nothing came back during determination."

Sound Testing 02

Part E Sound Testing — Multi-Phase Residential Development, Yorkshire

Client type
Regional housebuilder
Service
Part E pre-completion sound testing, failure analysis and remediation advice
Project type
New build residential — 60 units across four phases
Construction
Timber frame, separating walls and floors between semi-detached and terraced dwellings

Background

A regional housebuilder was running a phased residential development of over 60 units. Testing on the first phase, carried out by another acoustic consultant, had produced failures on several plots — a combination of failed airborne sound tests on the separating walls and failed impact sound tests on the apartment separating floors.

The failures were having real consequences. Building Control had declined to issue completion certificates for the affected plots, and mortgage applications were stalling on properties where buyers had already exchanged. The housebuilder needed a clear diagnosis of what had gone wrong and someone to take over and manage the testing programme for the remaining phases.

Our Approach

We started by reviewing the original test reports against the as-built construction drawings for every failed plot. The review identified two distinct causes. On two plots, the acoustic screed had been installed with a section omitted at one edge of the floor, creating a direct flanking path. On the remaining failures, a continuous perimeter blockwork wall had not been broken at the floor zone, allowing sound to bypass the separating floor through the wall structure.

Written remediation guidance was issued to the site manager and contractor for each category of failure, specifying exactly what physical works were required. A revised testing schedule was then agreed against the site programme.

We took over the testing programme for Phases 2 through 4, carrying out pre-completion testing for each phase as it approached handover and issuing reports to Building Control within 48 hours of each visit.

Outcome

All remediated plots passed on retest. Phases 2, 3 and 4 achieved a 100% first-time pass rate, with no failures, no delays to Building Control sign-off and no impact on the completion programme.

The housebuilder subsequently instructed us on a further Yorkshire development, citing the speed of turnaround and the quality of the remediation advice during the first programme.

"Getting the right diagnosis matters as much as the test itself. Knowing precisely why a plot has failed is what makes remediation work first time."

Licensed Premises 03

Noise Management Plan — Licensed Bar, Yorkshire Town Centre

Client type
Bar operator
Service
Noise survey and noise management plan
Project type
Retrospective compliance — external terrace and amplified music
Location
Town centre, Yorkshire

Background

A bar operator in a busy Yorkshire town centre had been trading successfully for several years, with an external terrace that formed a significant part of the venue's trade during warmer months. Following a change of occupancy at an adjacent residential property, two formal complaints were received by the local authority's environmental health team relating to noise from the terrace.

Environmental health had responded with a formal abatement notice, and the licensing authority had indicated that a premises licence review could be triggered if the matter was not resolved within a set timescale. The operator needed an objective technical assessment and a credible management plan to put to the authority.

Our Approach

We attended the venue on a representative Friday evening to carry out a noise survey during live operation. Measurements were taken simultaneously inside the venue, on the external terrace, and at the nearest residential receptor points.

The survey data showed that noise levels at the residential properties, while audible, were within a range where operational and physical controls would be sufficient. A full structural noise attenuation scheme was not necessary.

A Noise Management Plan was prepared covering: a revised closing time for the external terrace; a terminal hour for amplified music outdoors; a staff monitoring protocol; repositioning of one external speaker stack; and installation of a short acoustic boundary screen on the northern elevation of the terrace. The plan was submitted to the environmental health team and licensing authority with a covering technical note.

Outcome

The licensing authority accepted the Noise Management Plan without requiring a review hearing. The environmental health team confirmed in writing that, on implementation of the measures, no further action would be taken on the abatement notice.

The physical works and operational changes were completed by the operator within three weeks. The terrace has continued to trade within the agreed parameters without further complaint.

"A well-evidenced noise management plan nearly always carries more weight with a licensing authority than operational assurances on their own. The data does the work."
