Core Access Service
Track-mounted monorail scaffold and building maintenance unit (BMU) systems for high-rise curtain wall installation and long-term facade access. Self-powered platforms that reposition across the full elevation without repeated re-rigging. Engineered and DOB-permitted.
Large-scale curtain wall towers need a platform that can reposition across the full elevation without constant re-rigging. Monorail scaffold and BMU systems solve that.
Skybridge Access designs, permits, and installs monorail scaffold and building maintenance unit (BMU) systems for NYC high-rise curtain wall installation, facade work, and long-term maintenance access. A fixed track mounted to the building carries a trolley-mounted suspended platform that travels the length of the elevation under its own power — no repeated anchor changes as the crew moves across the building. We support both temporary monorail installations for active construction and permanent BMU systems for ongoing building maintenance after construction wraps.
Single-track systems for standard elevations; dual-monorail configurations suspend a wider platform from two parallel tracks for added stability on complex curtain wall runs.
Self-powered platforms that move continuously along the track, keeping pace with curtain wall installation crews on tall towers without rig re-anchoring.
Track systems installed for the duration of a construction or facade project, engineered to the building's specific elevation and schedule.
Building-integrated systems designed to remain in place for ongoing window washing and facade maintenance after construction is complete.
Monorail and BMU systems require engineered track and anchor design filed with NYC DOB, distinct from standard suspended scaffold permitting. We manage the full engineering package and permit filing process, from temporary construction monorail through permanent BMU installation.
Every job fully permitted, no surprises mid-project.
Track layout and anchor design matched to your building's elevation.
Emergency deployments and accelerated timelines when you need us now.
10+ years suspended access experience per team member.

A monorail scaffold system uses a fixed aluminum or steel track mounted to the building, with a trolley-mounted suspended platform that travels along the track. It allows a single platform to reposition itself across a full elevation without repeated re-rigging at separate anchor points.
Monorail scaffold is typically a temporary track system installed for the duration of construction or a facade project. A BMU is a permanent, building-integrated system left in place for ongoing window washing and facade maintenance after construction is complete. We work with both, including transitioning from temporary monorail access during construction to permanent BMU systems.
High-rise curtain wall towers and complex facade buildings where a traditional suspended rig would need constant repositioning. Monorail and BMU systems are common on large-scale new construction and Class A commercial/residential towers.
Yes — dual monorail configurations suspend a single wider platform from two parallel tracks, giving more stability and coverage for complex curtain wall and facade installation work.
Monorail systems require engineered track and anchor design filed with NYC DOB, distinct from standard two-point suspended scaffold permitting. We manage the full engineering and filing process for track-mounted systems.
Tell us your building's elevation, curtain wall scope, and timeline — we'll engineer the right monorail or BMU configuration and get the permit process moving.
