Fitting cleanliness in with I

nstalling a cleanroom into an existing facility with its inherent dimensional, access and other constraints was never likely to be an easy undertaking and certainly not cheap if using a bespoke construction project. The notion of using modular cleanroom constructions reduces the

cost somewhat but how can large modular rooms and space sensitive locations find an appropriately harmonious marriage? One approach, as used by modular cleanroom specialist,

Connect 2 Cleanrooms, is to make use of the latest construction industry software and technology and apply it to contamination control facilities. The software and approach used by Connect 2 Cleanrooms is Building Information Modelling (BIM) and this was instrumental in the success of the company’s largest off-site cleanroom construction project to date, the installation of a Monobloc panel system for global medical products and

communication and coordination between departments and clients provides a greater understanding of the design intent and allows for any errors to be identified and changes to be made at an early stage, thus reducing waste and saving money. Spanning 951m2

8, the cleanroom incorporates a separate change area suitable for up to 60 operators and a material transfer area. The main cleanroom area, which was constructed to house ConvaTec’s stitch bonding processes, has a footfall of 870m2 designed to achieve 21 air changes per hour.

ALIGNING STRUCTURES To meet the increasing demand for controlled environments for its products for advanced wound care, critical care and infusion devices in the healthcare industry, ConvaTec required a new cleanroom to be aligned with their current facility, where the corridors incorporate windows and doors. The company also needed the ability to expand further in the future. To ensure an accurate design in an already space-sensitive

facility, the use of Building Information Modelling (BIM) assisted the design stage for Connect 2 Cleanrooms. The Point Cloud 3D design software allows for a more accurate design, shorter lead times and a more cost effective approach. Improved

2 /// Cleanrooms & Contamination Control 2017

The cleanroom design incorporates high speed and hinged interlocking doors between the transfer and change areas to aid the flow of materials and personnel, whilst reducing the risk of contamination entering the cleanroom and in keeping with the aesthetics of the existing sensitive layout. At nearly 900 square metres, the cleanroom is at a scale similar to being able to house a couple of dozen large buses so the monitoring of critical parameters and the control of air flow is crucial, particularly during high usage and other potentially contaminating events such as staff shift changes.

AIR HANDLING The cleanroom has 60 variable speed controlled HEPA ceiling fan filters, which are all accessible externally via a suspended walkable ceiling to enable non-disruptive maintenance.
