Acoustic Comfort in Laboratories - Horsham

Client: Novartis
Project Managers: Arcadis

Scope: To provide world-class acoustics inside the laboratory areas of Novartis' UK research facility to give excellent working environments inside what can be challenging environments containing large quantities of noisy test equipment. This involved detailed survey work and computer modelling of the existing laboratories and extensive consultation with Novartis staff to establish how acoustic treatments can be incorporated without interrupting workflow or rediucing efficiency. The bottom photo shows a screenprint of the impulse dispersion pattern inside one of the laboratories.

Pharmaceutical Plant Cooling Compound - High Wycombe

Client: Johnson & Johnson
Project Managers: Modus Unitech

Scope: To design the acoustic treatment required to achieve the stringent planning noise limits for a new cooler compound. Due to the proximity of dwellings and a care home, extensive acoustic treatment was required to the equipment together with screening/bunding. The new compound can be seen in the bottom right hand corner of the photograph.

New Medical Centre and Library - Clapham, London

Client: United House
Architects: Studio Egret West and DLA Architects
Mechanical Consultants: Scott Wilson

Scope: To carry out the detailed acoustic design of the scheme to achieve the Employers Requirements and Planning Conditions. The Health Centre was designed to the new HTM 08-01 acoustic criteria, to ensure suitable speech privacy and acoustic insulation throughout the facility. The main library area doubles as a performance space for music and theatre and so detailed 3D modelling was carried out to determine the optimum compromise between the conflicting requirements.

New Laboratories - Cambridge

Client: Kilby & Gayford

Scope: To assist in achieving the stringent Home Office noise criteria for these new laboratories which form part of the Genome project. The photograph shows commissioning tests in progress for the extensive mechanical services required for this type of project .

Special Education Needs (SEN) School - Milton Keynes

Client: Milton Keynes City Council
Architects: Architecture MK
M&E Consultants: AMK

Scope: To acoustically design this new school specifically for pupils with ASD (Autistic Spectrum Disorder). This required several specialist acoustic environments to be created to achieve the required theruputic environment, in addition to the standard BB93 criteria. Full details of the project can be read in School Building Issue 10. Walnuts is one of several SEN school projects that Cass Allen have advised on .

New Care Homes - Kent PFI Project

Client: United House
Architects: Calford Seaden
Planning Consultants: Calford Seaden

Scope: To assist with achieving noise-related planning conditions for the site and also carry out Sound and Air Pressure testing to demonstrate compliance with parts E and L1A in this series of care homes built as part of the 'Better Homes Active Lives' PFI project for Kent County Council. The above photographs show the Morgan Stanley and Hopkins Field care homes.

New Health Centre - Wooton Vale, Bedfordshire

Client: NHS
Contractors: Terrapin Construction

Scope: To assist with achieving appropriate speech privacy between treatment areas and waiting areas. The photographs show sound insulation and reverberation tests in progress. In view of the low ambient noise levels surrounding this rural health centre it was necessary to specify electronic sound masking systems throughout the waiting areas.
