Prefabrication has been used in building construction for decades. Interest in offsite construction — including prefabrication, modularization, preassembly and offsite multitrade fabrication — has renewed in the face of growing building project complexity, increasing pressure to avoid cost overruns and scheduling delays.
A 2017 survey conducted by the consulting firm FMI provides some insight into the current use of prefabrication in the United States.1 More than 100 owner members participated in the survey, 11% of whom were involved in pharmaceutical manufacturing. Two-thirds of respondents reported that the offsite construction environment is different than it was just three years ago, with this change attributed primarily to labor shortages and increasing cost and schedule pressures. Other factors include access to improved technologies, as well as heightened concerns about safety, risk and increased quality issues.
As a design and engineering firm focused on the pharmaceutical industry, CRB has been leveraging offsite construction for more than a decade. It is a standard practice to evaluate the use of offsite construction for every project. Cleanroom walls and ceilings, mechanical/electrical modules and process and utility skids, among other elements, can be fabricated offsite and then transported for quick installation. Our North Carolina office targets a minimum of 25% of all project construction work to be executed offsite.
Leveraging offsite fabrication offers a range of benefits, including improved safety, schedule predictability and reduced costs. Fabrication of facility components in a controlled, offsite environment is safer than at the job site. Moving the construction/assembly of components offsite also reduces the number and density of laborers working on the job site, which leads to a safer work environment.
Overall project timelines are dramatically reduced because components are fabricated concurrently with construction of the building structure — and do not require a permit to initiate. Offsite fabrication minimizes project schedule risks due to weather or a lack of site resources — which also improves cost certainty.
Cost savings can also be realized by improving labor efficiency, minimizing construction waste and reducing the overall time to manage and deliver a project. Additionally, the standardization of components affords greater flexibility and scalability.2 Production of components in a controlled environment allows for repeatability, reduced rework and more reliable quality.2
Offsite fabrication is a new approach for many pharmaceutical companies. Maximizing the benefits of this approach requires the involvement of architects, engineers, tradespeople and fabricators at the earliest stages of a project — often leveraging the expertise of offsite fabricators early in the design. Some pharma procurement groups struggle transitioning from a traditional design–bid–build process to one of integrated partnerships. CRB has, however, seen that this approach actually provides our clients with much higher levels of cost certainty.
These challenges can be overcome by engaging a design and construction firm with demonstrated success leveraging offsite fabrication. CRB has extensive experience identifying and communicating the best opportunities for offsite fabrication early in the process and applies this knowledge to each new project. We work closely with major trade contractors from the earliest stages of a project to jointly develop a successful build strategy.
Our teams leverage the latest 3D modeling techniques to integrate design efforts from all partners into a single model. The result is a smooth process that helps CRB’s clients realize the huge benefits of offsite fabrication.
