There is a good probability that your local planning authority will demand that you conduct a noise survey for planning purposes if you are constructing a property, submitting a planning application or requesting approval to alter the use of a building. If you’ve never collaborated with an acoustics expert before, this may seem like a strange and even scary procedure. You can confidently locate the proper business and guarantee your planning application is supported with robust, credible acoustic evidence if you know what to look for, what questions to ask, and how the process works.
The Importance of Noise Surveys in Planning and Their Implications
Learning why local planning authorities request this sort of study is a good first step before beginning your search for an acoustics firm. In most cases, a noise survey for planning is necessary if the proposed development is going to be located very close to an existing or anticipated noisy source, such as a railway, a busy road, an industrial site or a licensed entertainment venue. When deciding whether to install acoustic glazing or mechanical ventilation to protect future tenants or not, authorities consider the results of a noise survey for planning to determine if the site is acceptable for the proposed use.
A delay, request for additional information, or outright rejection of your application could occur in the absence of a sufficient noise survey for planning purposes. As a result, doing it correctly the first time is not merely good practice; it is an absolute must.
Get Started with Credentials and Membership in the Profession
Credibility in the field should be your top priority when choosing an acoustics company. The UK’s Institute of Acoustics (IOA) is the trade group responsible for establishing criteria for acoustic consultants. It is recommended that you enquire about the consultants’ membership status with the IOA, preferably Associates or full Members, while searching for a company to do a noise survey for planning purposes. A further indicator of professional rank is being chartered.
Additionally, some acoustic consultants have accreditations that show their dedication to technical rigour and quality management, or they are corporate members of relevant professional groups. Planning and environmental health officials will check these credentials to make sure that the expert who conducted the noise survey for planning is certified. If the local authority challenges or rejects a report that wasn’t written by someone with the right credentials, your project will be delayed considerably.
Evaluate Their Appropriate Background
The field of acoustics is vast, and not all acoustic service providers will have the necessary expertise to carry out a noise survey for planning purposes in your specific setting. Enquire about the consultant’s background in doing noise assessments relevant to planning for your specific type of development when contacting them. Select a firm with deep knowledge of residential schemes in close proximity to road traffic noise. They will be well-versed in the applicable British Standards, planning policy guidelines, and assessment procedures.
The National Planning Policy Framework and its technical notes, along with British Standards like BS 4142 for commercial and industrial noise and BS 8233 for building sound insulation and noise reduction, are usually followed when submitting noise assessments as part of planning applications in England. An experienced acoustics firm conducting a noise survey for planning purposes should have no trouble outlining the specific regulations and guidelines that are relevant to your project and why they are important.
Get References and Work Samples Requested
If you are looking for a reliable acoustics firm, ask to see some of the noise survey for planning reports they have prepared in the past. You can get a feel for their work quality, depth, and presentation by looking at sample reports; however, due to confidentiality concerns, certain identifiable details may be withheld. In addition to being technically correct, a well-structured report should be prepared in a way that a planning officer who isn’t an acoustic expert can easily comprehend and use.
If at all feasible, see if you can get in touch with a reference from a client who, say, hired you to conduct a noise survey for planning purposes. The decision-making process can be greatly aided by first-hand descriptions of the company’s communication style, process management methods, and responses to planning authority requests.
Evaluate Their Strategy Regarding Tools and Procedures
The tools and rigorousness of the monitoring methods utilised greatly impact the quality of a noise survey for planning purposes. Enquire about the frequency of equipment calibration to industry standards and the brand of sound level meters used by any potential acoustics firm. Class 1 sound level meters that have been correctly calibrated are typically required for tasks connected to planning, and documents of calibration should be made available upon request.
Ask them when exactly they intend to monitor the noise levels at your site and for how long. In order to conduct an accurate noise survey for planning purposes, it is common practice to monitor the area during the day, evening and night, or at other times of day as may be appropriate based on the receptor’s sensitivity and the noise source’s characteristics. A business needs to be thoroughly investigated if it suggests a modest or very brief monitoring program without providing a solid technical basis for it.
Gain a Comprehensive Understanding of the Service
Make sure you know precisely what the acoustics firm’s cost covers before hiring them to conduct a noise survey for planning purposes. Report writing, pre-application meeting attendance, and responses to planning authority inquiry are often charged separately from the physical monitoring portion of the task by some organisations. From the first site inspection all the way to the final approval, other companies provide a more all-encompassing service.
Rarely is a noise survey for planning a simple process. Environmental health inspectors may ask for further information, planning officials may return with questions, and a second round of monitoring may be necessary in some instances. It will be more pleasant and less stressful if you know in advance how these things will be handled and how much they will cost.
Make an Effort for Open and Honest Communication
It is important that collaborating with an acoustics firm feels like a team effort. The consultant doing your noise survey for planning purposes has to be approachable, willing to answer your concerns, and transparent about the technique. They should also keep you updated at every step of the process. Misunderstandings, delays, and reports that fail to accurately reflect the planning authority’s precise requirements can result from clients and acoustic consultants failing to communicate.
Take note of the company’s communication style throughout your first meetings with them before committing to them. Do they answer? When you explain the needs of your project, do they pay close attention? Inquisitive enquiries on the location, intended use, and planning environment should be asked. A consultant’s ability to tailor a noise survey for planning to your specific requirements is directly correlated to how invested they are in comprehending your project.
Evaluate Prices Thoroughly
Although it shouldn’t be the sole consideration, cost is an important consideration when ordering a noise survey for planning purposes. Divergent quotations from different businesses could be due to discrepancies in the project’s scale, the consultant’s expertise, the equipment’s quality, or the time allotted to it. A remarkably low price might be an indication of cutting corners, which could lead to a report that doesn’t meet the planning authority’s standards and ends up costing you more in the long run due to delays and extra labour.
If you want to know what you’re paying for when you compare quotations, make sure to ask each provider to explain their cost in detail. By doing so, you will be able to compare the two sides fairly and find any holes in the planned scope of work.
Put Your Faith in the Method
Investing in a professional acoustics firm to conduct a noise survey for planning purposes is a gamble on the outcome of your planning application. In order to hire a consultant who can provide an authoritative and credible evaluation that boosts your application’s chances of success, it’s important to check their credentials, evaluate their experience, look over their past work, and ask the correct questions regarding methodology and scope.
Instead of being a meaningless formality, a noise survey for planning serves as a technical evaluation that might have an impact on the final decision. Consequently, one of the most crucial choices you’ll have to make early on in your development project is selecting the correct firm to execute it.
