Pre & Post Construction Cleaning
3 Phases of Data Center Construction Cleaning
We offer mission-critical construction cleaning and post-construction cleaning in data centers, cleanrooms, and other controlled environments. For most construction operations, there are 3 stages of cleaning in data centers.
Phase I – Maintenance
On-Site Daily Data Center Cleaning
Technicians remain on-site throughout construction to maintain cleanliness
Areas are cleaned to interim industry standards during the process
Assist with commissioning spaces to prepare for customer inspection
Services are billed as standard time and material during this phase
Phase II – 5 Micron Clean
Post Air Handler Activation Cleaning
Complete facility cleaning to 5-micron levels to remove airborne particulates
Perform full testing and inspection, documenting all issues and concerns
Provide a detailed environmental report with action items
Prepare the environment for upcoming final inspection and system startup
Phase III – .3 Micron Clean
Inspection Turnover Cleaning
Final clean performed to 0.3-micron ISO 14644 and ASHRAE standards
Ensure all areas are contaminant-free before equipment installation begins
Deliver a full environmental report to the project or construction group
Confirm facility is compliant, clean, and ready for operational turnover
