What we do
Transforming the approach to Riser Management
By taking a holistic approach during early stages of design, incorporating a versatile and lightweight riser unit overcomes the multiple challenges faced by contractors throughout the construction process. This is the beginning of a journey that reduces risk, minimises waste and drives efficient construction processes.

Welcome to AlphaRiser
The integrated and versatile approach to Riser Management.
Eliminate the creation of a floor void
AlphaRiser systems are incorporated into the construction process from the beginning of the programme. As the core and frame is assembled.
Eliminate temporary concrete shuttering
AlphaRiser is built into the structure. The unique outer frame of the unit integrates into the floor slab and provides the shuttering for the slab edge.
Eliminate temporary edge protection
The finished surface is safe to walk on and eliminates the need for temporary protection throughout the remainder of the build programme.
Simple adjustable system to position and fix MEP services
Once MEP works commence, penetrations can be marked up and cut out through the lightweight GRP grating to allow services to pass through.

Off-Site Fabrication: The Future of Riser Installations
Riser floor systems are an important part of a building because they connect several disciplines at once, including structure, building services, and fire performance. These systems affect the project from the very...
Modern Methods of Construction: What They Mean for Riser Design
Modern Methods of Construction (MMC) are radically changing the UK high-rise construction industry, prioritising off-site production and assembly, efficiency, and sustainability. For riser design, these methods mean a...
The Customer Success Map: From Design to Certification
Riser floor systems are often treated as a defined scope within a project. In reality, they span multiple stages of delivery, from early design through to installation and final sign-off. They bring together structure,...
Avoiding Rework: The Hidden Cost of Late Design Changes to Risers
In the fast-moving environment of modern construction, change is inevitable. The design and positioning of MEP services evolve, client requirements shift, and coordination between trades must continually adapt. But few...
GRP vs Steel: Embodied Carbon and Sustainability in Riser Systems
Embodied carbon targets are now front and centre for developers and Tier 1 contractors working on large commercial schemes. The UK Net Zero Carbon Buildings Standard has set upfront embodied‑carbon benchmarks in the...
Fire-stopping in service risers – what you need to know
Service risers are critical vertical shafts that carry vital building services such as electrical cabling, plumbing, communication cabling, firefighting water pipes, and HVAC systems.
Why Early Design Coordination Is Critical for Successful Riser Management
In the early stages of a construction project, coordination between disciplines is often fast-paced and fluid. Structural elements are being fixed, M&E layouts are still evolving, and the riser voids – the vertical arteries of the building – are often overlooked until late in the design process. Yet these spaces are essential to the safe and efficient routing of services throughout the structure.
Understanding and Navigating the Risks in Riser Management: An Outlook by Comtec
Riser shafts are often overlooked in early construction design, leading to delays, added costs, and safety risks. With effective planning and riser management, these issues can be prevented to ensure a building’s safety and long-term performance.
Rethinking Riser Management in Modern Construction
Riser zones often cause delays and added costs in construction. AlphaRiser by Comtec simplifies riser management with an integrated system that reduces risk, cost, and waste while improving project efficiency.
