The project phase is where the risk is highest, and where the discipline is most often underestimated.
The final months of a build carry the greatest risk
The final three to four months before handover are the most critical window in any data centre programme. Electrical, HVAC, civil, plumbing and multiple OEM teams are all working to close overlapping scopes. Movement is at its peak, dust generation is at its peak, and small items like cable ties and insulation offcuts are routinely left behind when cleaning is not engineered into the programme.
“During this phase cleaning has to be maintained because dust levels from the ongoing work are high and people movement is at its peak. If this phase is not managed properly, in the long run it impacts the life of every asset inside, whether it is engineering or IT.” –Girish A Sharmaa
Contractors on site wear PPE for their own scope, not for contamination control. Cleanliness is not their core deliverable. That responsibility sits with the facilities management partner brought in specifically for the environment.
What happens when particle control is treated as an afterthought
The operational consequences of poor pre-commissioning cleaning are not visible on day one. They appear months later, at first shutdown or first maintenance cycle.
Dust settles on the internal components of switchgear and inside cooling systems. Cable ties, cable offcuts and insulation debris have been found inside electrical panels months after handover. On the cooling side, dust chokes filters, reduces return air, and forces the system to consume more power to deliver the same cooling output.
“This directly impacts the life of the asset. Dust on filters chokes return air into the air conditioning system, which pushes up power consumption to maintain the same cooling output.” – Girish A Sharmaa
The cost is not only energy. It is asset life, warranty risk, and unplanned downtime inside a facility whose entire value proposition is uptime.
