BIM A cleanroom of this size would typically use an Air Handling


Unit (AHU) to supply HEPA filtered and temperature controlled air. However, Connect 2 Cleanrooms proposed the use of localised air conditioning and dehumidifier units to supply processed air to fan filter units. This approach meant a significantly lower initial investment and it is more energy efficient when operational than an AHU.


MONITORING AND CONTROL ConvaTec uses Connect 2 Cleanrooms’ ECO loop control system with temperature and humidity control for monitoring crucial environmental parameters within the cleanroom. The ECO loop control system provides greater energy efficiency over conventional cleanrooms by continually monitoring contamination levels and pressure, adjusting airflow dynamically to ensure that energy usage is kept low without taking the room out of classification. A bespoke touch screen control system was installed to continually log all these data parameters, which integrates with ConvaTec’s current BMS. The integrated alarm alerts operators when these parameters vary beyond a specific threshold such as pressure differential and temperature and humidity. Following the installation, a

detailed commissioning process was carried out to ensure the cleanroom is functioning as it should. Extreme testing of all


elements, alongside the design against resilience, ensures the room continues to operate around the clock without a break even if a unit fails.


APPLYING BIM TO CLEANROOM DESIGN With increasing business demands and the ever growing need for a less disruptive construction and more efficient design process, Connect 2 Cleanrooms is consistently looking for new processes to offer more accurate and effective designs coupled with a reduction in installation time for its modular cleanrooms. The company does the design and manufacturing of its hard and soft wall cleanrooms in-house and delivers ISO 14644-1:2015 standard compliant products.


❱ ❱ Point clouds within the Building Information Model provide crucial reference points for the final cleanroom design


The introduction of Building Intelligence Modelling (BIM) is another investment added to the company’s design portfolio, offering customers a more efficient and accurate service. Through BIM, the UK construction industry is experiencing


its very own digital revolution, combining efforts of people, processes and technology and Connect 2 Cleanrooms decided to apply this to its own operations. According to Joe Govier, Managing Director of Connect


2 Cleanrooms, the use of BIM allowed the company to think beyond CAD drawings and more towards data to help it understand the building to be occupied, so Connect 2 Cleanrooms could apply its technology more efficiently. “By analysing historic data and understanding the length of time to complete our cleanroom installations, we could forecast our activities and the time taken from inception to installation of the cleanroom, which meant we could optimise our people and processes more effectively, making cost and time savings,” said Govier. “The offsite construction method and the Point Cloud 3D scan adopted for this installation ensured that the clients’ cleanroom was brought in on time, on budget, resulting in a happy client,” he concluded Connect 2 Cleanroom will be showcasing its modular cleanroom systems at Advanced Engineering on 1 and 2 November at the NEC, Birmingham on stand B50.

BIM AND THE CONVATEC POINT CLOUD


Building Intelligence Modelling is a process for creating and managing information across a project’s lifecycle. One of the key outputs of this process is the Building Information Model, the digital description of every aspect of the built asset. This model draws on information assembled collaboratively and updated at key stages of a project. Creating a digital Building Information Model enables those who interact with the building to optimise their actions, resulting in a greater whole life value for the asset. At ConvaTec, a point cloud 3D scan of the entire building


was conducted within the initial stages of the project to provide a virtual view of the space the facilities occupied. A Point Cloud is a collection of data points defined by a given coordinates system. In a 3D coordinates system, for example, a point cloud may define the shape of some real or created physical system. The point cloud was then used within the overall model


created for the project to ensure all aspects of the current facility were taken into account in the final design.
