The question of modular versus conventional clean room construction is increasingly common in high-tech industries, and one that may have a different answer depending on each individual project. Speed to market, however, is critical for almost all manufacturing companies, and it’s particularly important for the pharmaceutical and biopharmaceutical industries, which need to maximize the patent protection period after what is usually a long and expensive product development cycle. It’s also crucial for the microelectronics industry where technology changes on a near-daily basis.
Facilities are also being designed and constructed for maximum adaptability and to provide for minimal operational disruption or downtime. In order to meet this need, facilities must be constructed of components that not only allow change but provide the utmost flexibility as needs change in the market. Moving forward, it will be important to fully understand a project’s requirements and to separate required functional needs (must-haves) from aesthetic preferences (nice-to-haves). This article will examine critical selection criteria for determining the most efficient and cost-effective clean room construction technique, with a particular emphasis on the potential benefits offered by modular construction.
Construction activities invariably result in disruption to areas surrounding the construction site. For example, dust generation, increased personnel, noise and vibration, access restrictions and accidental damage can negatively impact any job site. Pharmaceutical and semiconductor facilities are particularly sensitive to the dust and debris generated by conventional construction, which can be carried by personnel into other areas or drawn into ventilation inlets.
Availability of skilled labor is another consideration. Adherence to a construction budget can be greatly affected by labor instability and poor availability of construction materials. For example, after hurricane Katrina, resources for sheet rock were scarce since all available materials were being purchased to rebuild affected areas. And, constrained laydown areas can also be a challenge. Lack of storage space can potentially delay the build process and impose additional costs.
