We would always prefer to be involved in facility concept and layout at the earliest stage possible as we can bring valuable experience to the overall design-development process.

During design we will consider:

• Overall physical rooms and plant space layout
• Method of structural support of the rooms and plant
• Confirmation of required room environmental parameters of room
• Confirmation of client process equipment services
• Load estimation for the different services systems
• Selection and layout of plant and systems to produce the required environments
• Consideration of control philosophy
• Detailed sizing and features required in each system
• Production of schematic system drawings
• Production of plant and equipment schedules
• Production of detailed installation layout drawings
• Checking at each stage of design

CRC stands out from many cleanroom companies since we have a very strong in-house design capability. CRC’s directors normally set the broad layout and design philosophy whilst all CRC project engineers are qualified and experienced for involvement in the design process.

Controlled Environments almost always have a high density and complexity of services, particularly building services including HVAC, electrical, piping, control and telemetry. All of CRC’s engineers have built their careers on a foundation of building services engineering. Extensive use is made of CAD and CAD drawing and building services software design and selection packages.

Selection and application of cleanroom structures and finishes is traditionally learnt by experience and CRC has the significant experience of both traditional site-built and contemporary pre-manufactured rapid-build structures. An example is CRC’s prefabricated CMP fast-track Cleanroom partition and ceiling system, now used on the majority of projects.

CRC maintains links with experienced and qualified associates, providing detailed design-input for steelwork, architectural, civil and building work and high-purity process plant and distribution systems. We have successfully completed numerous projects with their involvement.

Most of CRC business is undertaken on a design and build basis and even where an external consultant’s design is provided by the client, we expect to retain a responsibility for the successful operation of the design.

Naturally, we operate our core design processes in accordance with all of the applicable design codes and standards and these include:

• All applicable BSI and ISO standards and codes of practice
• EN ISO 14644 cleanroom standard
• IES recommended practices
• HVCA specifications
• CIBSE technical design guides
• IEE Regulations
• ACDP recommendations
• ACGM recommendations
• CGMP recommendations
• CGLP recommendations
• ISPE/FDA Baseline Pharmaceutical engineering guides
• Home Office Veterinary Codes of Practice
• BRE guides BCGA codes of practice
• BSRIA technical notes and application guides
• DOE/PSA technical specifications
• HSC advisory publications
• The Building Regulations
