Adjustable Precast Stair System – Scissor Type

Reusable Adjustable Precast Stair Formwork System

Reduce Stair Forming Labor & Reset Time on Repetitive High-Rise Projects

This field-tested adjustable double-flight stair formwork method was developed and reused across multiple multi-storey concrete projects.

Designed specifically for repetitive high-rise construction, this system allows rapid floor-to-floor adjustments by swapping pre-cut rise/run inserts between reusable nosing units — eliminating the need to rebuild stair forms from scratch when floor heights change.

If you are pouring repetitive concrete floors, this method can reduce reset time, improve consistency, and eliminate custom one-off stair forming for every level.

What Problem This Solves

Traditional stair forming on high-rise projects often means:

• Rebuilding forms for each floor

• Time lost adjusting for minor height differences

• Labour-intensive layout

• Limited reuse across projects

This adjustable system allows:

• Double-flight pours in a single reusable setup

• Fast rise/run adjustment using saved insert pieces

• Repeatable, controlled workflow

• Practical reuse from project to project

System Overview

This method demonstrates:

• Reusable double-flight stair form configuration

• Interchangeable rise/run filler insert system

• Efficient reset workflow between pours

• Field-proven jobsite setup used on real high-rise projects

Reusable Core Components (Long-Term Advantage)

Primary components that carry forward from job to job:

• Reusable nosing units (plastic or steel)

• Saved rise/run insert sets

Remaining formwork components (side forms, bulkheads, platform framing) can be adapted to suit each project.

This makes the system scalable and economical — without requiring expensive factory mould systems.

Material Recommendations

Nosings: Powder-coated steel or heavy-duty molded plastic

(Plastic preferred long-term for stripping and durability.)

Rise/Run Inserts: Custom-cut reusable plastic filler boards saved and reused throughout the project.

Who This Is Designed For
