Standard, Modular and Custom Building Maintenance Units

At Facade Access Solutions, we deliver complete façade access systems engineered for performance, safety, and reliability across North America. From commercial towers to mixed-use and institutional buildings, our Standard, Modular, and Custom building maintenance units (BMUs) provide efficient façade maintenance throughout your building’s lifecycle.

Standard BMUs — Proven and Reliable

Designed for new construction and existing buildings, our Standard Series offers robust, compliant, and cost-effective façade access solutions. Each building maintenance unit is built for long-term durability and minimal downtime, giving building owners confidence in safe, efficient operations. Standard BMUs are suitable for flat roofed buildings where the roof structure supports a horizontal track system. Engineered for performance. Built for compliance.

Modular BMUs — Flexible and Scalable

Our Modular building maintenance units combine interchangeable components and adaptable configurations, making them ideal for diverse façade layouts and complex facades. Built to meet strict safety standards, they integrate easily into existing structures and evolve with your building’s needs.

Custom BMUs — Tailored to Design Vision

Every skyline is unique. Our Custom building maintenance units are engineered for curved façades, angled rooflines, and distinctive architecture, providing safe, efficient, and compliant access without compromising design. These units are specifically designed for buildings with complex facades, where standard equipment cannot reach every surface. Backed by decades of expertise, each system is crafted to regional codes and long-term performance.

Facade Access Solutions North America – Global Expertise, Local Delivery

As part of the Alimak Group, Facade Access Solutions North America delivers engineering expertise supported by trusted global brands including Tractel, Manntech, and CoxGomyl. These manufacturers have decades of proven success designing and manufacturing building maintenance units, davits, and integrated facade access systems for some of the world’s most complex towers. That global foundation means rigorous international standards back every system we deliver in North America for safety, reliability, and long-term performance.

Across the United States, our work includes high-rise commercial, residential, and mixed-use projects where facade maintenance is critical to lifecycle value. In Canada, we support institutional, healthcare, and educational buildings where compliance and operational safety cannot be compromised. In Mexico, our portfolio extends to landmark towers and modern developments that push the boundaries of architectural design.

Building maintenance units must comply with strict safety requirements and regulations, including OSHA 1910.66 and ANSI/ASME A120.1 in the United States, as well as CSA Z271 in Canada. Engineered safety devices control and monitor all machine functions to provide complete safe access and fall protection for operators.

Operators must maintain detailed logs, perform pre-use checks, and conduct periodic third-party audits to remain compliant. Our systems meet the highest safety standards, with features such as automatic braking, emergency power backup, and overload detection. For inspection, safety, and compliance services, our team supports building owners and operators at every stage.

Frequently Asked Questions

What is a Building Maintenance Unit (BMU) and why is it important for façade access?

A Building Maintenance Unit (BMU) is a permanently installed system that enables safe and efficient façade maintenance on high-rise and complex structures. BMUs provide controlled access for window cleaning, inspections, and façade repairs. At Façade Access Solutions North America, our Standard, Modular, and Custom BMUs are engineered to meet OSHA, ANSI, and CSA requirements, ensuring long-term safety, reliability, and compliance across commercial, residential, and institutional buildings.

How do Standard, Modular, and Custom BMUs differ?

Our Standard BMUs offer proven, cost-effective solutions for common façade layouts. Modular BMUs provide flexibility with interchangeable components that adapt to evolving building needs, while Custom BMUs are fully engineered for complex geometries, curved façades, and unique architectural designs. Across the U.S., Canada, and Mexico, we tailor each system to local codes and environmental conditions to guarantee safe and efficient façade access.

How often should BMUs be inspected and serviced?

Building maintenance units should be inspected at least annually or more frequently depending on usage, environmental exposure, and local regulations. Regular servicing keeps your equipment compliant with OSHA, ANSI, and CSA standards and helps prevent costly downtime. Our qualified technicians perform mechanical, electrical, and safety system checks to maintain optimal performance and worker safety. Contact Façade Access Solutions for a maintenance schedule based on your building’s needs.

Can facade access systems be retrofitted to existing buildings?

Yes. We specialize in retrofitting building maintenance units and façade access systems for existing buildings throughout North America. Our engineers assess your current structure, evaluate load capacity, and design a compliant, efficient system that integrates seamlessly with your building’s architecture. Retrofit and refurbishment solutions reduce disruption, extend equipment lifespan, and bring older properties up to current safety and performance standards.

Other Important Info

BMU Technical Resources and Specifications
Supporting Design Teams
Installation and Support Services

We provide detailed technical documents related to equipment and machinery to support architects and engineers, including:

  • Load capacities and outreach specifications
  • Track design and compatibility details
  • Compliance certifications

Integrating building maintenance unit planning early helps streamline approvals, reduce conflicts, meet local safety codes, and maintain horizontal alignment. Our integrated design services support architects and engineers through every phase of the construction process.

A façade access system is only as effective as the service behind it. Our approach covers the full lifecycle of your building maintenance and cleaning system.

End-to-End Consultation

We collaborate with architects, engineers, and contractors from the outset to evaluate constraints and requirements. Early consultation during the construction phase leads to innovative solutions that suit your building’s shape and structure.

Precision Design and Engineering

Our in-house engineers translate project needs into safe, efficient building maintenance unit designs with control mechanisms suited to each building. We account for loads, roof space, rail configurations, and the specific complexity of every facade.

Expert Installation

Technicians install systems with precision, coordinating with site teams to minimize disruption and meet schedules. Each unit is installed and tested for safe operation before being handed over to the building’s maintenance team.

Operator Training

We provide hands-on training for building staff, covering safe operation of automatic and manual machines and systems, inspections, and emergency procedures. Training covers the full range of user responsibilities, from daily pre-use checks to maintaining detailed operation logs.
