Project Description
Euler Engineering was engaged to undertake a non-intrusive as-built capture of the existing stair void and surrounding structure to support the design and construction of a new three-storey staircase. The project required accurate documentation of the existing setup and available void where the new stair would be built up, with no reliable as-built drawings available.
The facility remained operational throughout the works, requiring a fast, non-intrusive data capture approach.
Scope & Methodology
-
Performed non-intrusive 3D laser scanning of the existing stair void and adjacent areas
-
Captured floor edges, slab soffits, beams, columns, walls, and interfaces surrounding the void
-
Recorded existing stair elements, temporary works, and access constraints
-
Captured vertical clearances, level-to-level heights, and spatial relationships across three storeys
-
Registered all scans into a single, high-resolution point cloud representing true site conditions
-
Developed a coordinated 3D model of the void and surrounding structure to support stair design
Outcome & Value
-
Delivered an accurate digital as-built of the existing setup and stair void
-
Enabled designers to confidently develop a new three-storey stair within the available space
-
Reduced risk of clashes with existing structure during design and construction
-
Eliminated the need for repeated site visits and manual measurements
-
Achieved all outcomes through non-intrusive capture with minimal disruption to operations
Accuracy
-
Millimetre-level accuracy achieved through laser scanning
-
Data suitable for structural design, architectural coordination, and construction planning
