200 Apartments

Planning permission was granted to convert the former Norwich Union (Aviva) offices into 200 apartments.

Acoustic Design and Testing

IEC was commissioned to provide acoustic design and testing services for the project to demonstrate compliance with Approved Document E of The Building Regulations. The range of services provided included advice on separating floor and wall constructions to meet performance standards, calculation of absorption within communal areas to meet Requirement E3 and Pre-Completion Testing (PCT) for Building Control sign-off.

Site Visits and Testing

A number of site visits were carried out during the scheme to review the works as they progressed and carry out testing when sections of the building were at sufficiently complete (2nd fix stage). Testing was often undertaken outside of normal working hours to ensure quiet conditions during the test procedures and not impede site operations during the working day.

Airborne and Impact Sound

The development achieved a high level of airborne and impact sound insulation between flats and easily met the minimum performance standards from Approved Document E. ANC approved sound insulation test reports and certificates were issued by IEC for the development and presented to Building Control as part of the sign-off process.

Calulation Method B

Using calculation Method B which takes into account all surface finishes in each octave band, it was also demonstrated that communal areas adequately controlled reverberant sound and met Requirement E3.

IEC is registered under the Association of Noise Consultants (ANC) Scheme (No. 170) for Pre-Completion Testing.

    Building Bulletin 93 (BB93) Acoustic Assessment

    A new single-storey building to provide additional classrooms was built at Notre Dame Prep School in Norwich. The school is a leading independent preparatory school and the new building was required to comply with Building Bulletin 93 (BB93) “Acoustic Design of Schools”.

    Environmental Noise Survey

    IEC carried out  an environmental noise survey to establish the existing ambient noise levels at the location of the building in order to advise on a façade insulation scheme to mitigate noise ingress. Rain noise was also considered as part of the assessment.

    Sound Insulation Testing

    The airborne sound insulation performance of internal separating walls between classrooms and adjoining offices was calculated, as well noise transfer from circulation spaces. Recommendations for internal separating walls and associated flanking structures were made to meet BB93 sound insulation requirements.

    Reverberation times of each space were considered and the amount of additional sound absorption required to allow good speech intelligibility determined.
