EscaTEQ Case Study – WTC Amsterdam (Class C)

Case Identification

Facility: WTC Amsterdam (Office Tower)

Escalators: 18 indoor

Operating: ~16 hours/day

Traffic: ~750 riders/day

Starting Condition: Class C (based on observable surface contamination characteristics at time of service)

Photo Documentation

Before Cleaning – Class C surface condition (17-04-2026)
After Cleaning – Post-cleaning condition after 6 cycles (17-04-2026)

Cleaning Cycle Definition: One complete rotation of the escalator step band, during which each step passes the operator once and receives one cleaning pass.

Total Cleaning Cycles Executed: 6

Observed Active Cleaning Duration (step-band contact time): Approximately 6 minutes (field timed)

Traffic & Cleaning Frequency

Traffic Level: Moderate

Recommended Frequency (EscaTEQ Method): Monthly

Actual Frequency (Applied at Site): Biweekly

Condition vs Frequency

Starting Condition (Observed): Class C, based on observable surface contamination characteristics including surface coverage, embedding within step grooves, contamination type, and distribution across exposed step surfaces.

Recommended Frequency (EscaTEQ Method): Monthly

Actual Frequency (Applied at Site): Biweekly

Interpretation: Weekly is the EscaTEQ Method™ recommended starting point for this traffic classification. Biweekly was the actual site-applied frequency during the documented period and maintained observed condition at this site. Final frequency should remain subject to contamination rate, facility profile, OEM guidance, and consultant judgment.

Executive Summary

Executive Summary

– Office tower environment with moderate traffic.

– 18 indoor escalators operating approximately 16 hours per day.

– Starting condition documented as Class C.

– Actual site-applied frequency: biweekly.

– EscaTEQ Method™ recommended operational starting point for this profile: Monthly.

– Documented outcome: observed condition was maintained during the review period.

Site Profile

Office tower environment.
18 indoor escalators.
Approximately 16 operating hours per day.
Approximately 750 riders per day.
Known constraints: None documented.

Before Condition Assessment

Observed surface contamination consistent with Class C at time of service.
 
Contamination Type: Residual surface-level particulate with minor oil presence.
Embedding Within Step Grooves: Light, non-compacted presence within grooves.
Step Definition Visibility: Clearly visible across full width.
Overall Condition Statement: Surface-level soiling consistent with Class C – light contamination, no heavy compaction, no deep embedding, and clear step definition.

Work Performed

Method: EscaTEQ Method™
Application type: surface-only, low-moisture cleaning applied only to exposed step surfaces.
Operator configuration: single operator.

Inputs & KPIs

Application Parameters

Duration: ~6 min/escalator.

Liquid usage: ~120 ml/escalator.

Pads: 1 per escalator.

Number of cycles performed: 6.

Actual cleaning frequency applied: Biweekly.

Outcomes

Observed reduction in surface soil.
Observed condition during review period: maintained.
No known or reported operational disruption identified within the documented site record for this case study.

Outcome Narrative

Cleaning maintained observed condition during the documented review period using low resource input.
No condition escalation was observed within the documented period.

Lessons Learned

Low resource usage was documented for the applied cleaning cycle.
Preventive surface-cleaning frequency should remain subject to contamination rate, facility profile, OEM guidance, and consultant judgment.

Verification

Photographic documentation before and after cleaning.
