Challenge
Mirrored curtain walling streaks badly, and the elevation was too large to clean efficiently one drop at a time.
Three technicians rigged in parallel so adjacent drops were cleaned wet-on-wet and the finish stayed even across reflective glass.
Project context
Building described without naming the client. Three simultaneous rope access drops from roof anchors.

Mirrored curtain walling streaks badly, and the elevation was too large to clean efficiently one drop at a time.
We rigged three technicians in parallel from roof anchors so adjacent drops were cleaned wet-on-wet. All three worked to the same pace and descent line to keep the finish even between drops.
A consistent, streak-free finish across the mirrored elevation, with the programme compressed and no access equipment standing at street level.
