Cleanroom Design

When you partner with Coombs Contracting for your cleanroom project, you gain the advantage of a single source for every aspect of the project cycle, starting with world-class design services.

We begin with a thorough analysis of your process requirements and site needs, and then our technical specialists create a cleanroom design that suits your exact specifications, budget, and schedule.


  • Modular cleanrooms are available in hardwall, softwall, or stretchwall configurations.
  • Cleanroom structures are either self-supporting or conversions of existing spaces.
  • Advanced air-handling and filtration systems prevent contamination from airborne pollutants such as dust, microbes, and other particles.
  • The operator maintains strict control over the interior environment, including airflow rates and direction, air pressure, temperature, and humidity.
  • Each cleanroom is tested and certified to ISO, FDA, USP, and/or cGMP standards.

Project Management

Once the design is approved, your cleanroom project is assigned a project manager who will serve as your single-point of contact throughout the project’s entire lifecycle. Your project manager leads a team of Coombs Contracting professionals who oversee each step of the construction and installation process.

The project manager is responsible for every detail, including…


  • Ensuring that all project specifications are followed.
  • Managing all material procurements.
  • Site staging.
  • Onsite supervision.
  • Coordination of cleanroom build inspections.
  • Final balance, testing, and certification tasks.
