Steel Staircase Installation

Presenter		Project
Location		Date

Steel staircase installation involves lifting, positioning, and bolting prefabricated steel stair flights and landings.
Stair flights are heavy, awkward shapes that require careful rigging and lift planning for crane operations.
Unprotected floor openings at stairwells present serious fall hazards during and between installation phases.
Temporary edge protection or covers must be maintained at stairwell openings until permanent handrails are fitted.
Bolt connections between flights, landings, and supporting steelwork must be torqued to design specification.
Workers positioning stair flights at height need fall arrest equipment and safe working platforms.
The erection sequence must ensure structural stability at each stage as flights are added.
Temporary bracing may be required to stabilise the staircase until all connections are made.
Stair treads may be open mesh or have temporary covers — slip-resistant surfaces must be confirmed.
Installation often takes place inside building cores with limited crane access and tight spaces.

Fall hazards	Open stairwells and unprotected edges create fall-from-height risks throughout the installation process.
Lifting risks	Heavy, awkward stair flights require precise rigging — uncontrolled loads can swing and strike workers.
Structural stability	Incorrect erection sequence or incomplete bolting can cause a partially erected staircase to collapse.

Don't

Prepare a lift plan for each stair flight and landing being craned into position
Maintain edge protection at stairwell openings at all times between installation phases
Wear fall arrest harnesses when working at unprotected edges during positioning
Follow the erection sequence specified by the structural engineer precisely
Install temporary bracing until all permanent connections are completed and torqued
Torque all bolted connections to the specified values and record the results
Provide safe working platforms for operatives making connections at height
Use taglines to control stair flights during crane lifts in confined core areas
Inspect temporary covers and edge protection at stairwells daily
Brief the team on the lift plan, rigging, and connection sequence before each flight
