Geo Week 2026 Concrete Laser Scan Flatness Deliverable

Geo Week 2026 Conference, Denver, The Committee Booth
Feb 16-18, 2026

THE COMMITTEE
American Society of Concrete Contractors (ASCC)
American Concrete Institute (ACI) 117-0L – Laser Scanning

PARTICIPANT

AUDIENCE
concrete contractors, designers, owners, flooring contractors, service providers, surveyors, educators, etc.

FORMAT AND REPORTING
• Preload the deliverables from each participant and present at Geo Week 2026 The Committee Booth on Screen
• Live demonstration from participants at The Committee booth (no sales pitch will be allowed)
• User report from The Committee will be produced and free download
• Concrete International Article with acknowledgment to the participants (TBD)

WHAT WILL BE PROVIDED
• One single registered and georeferenced E57 file from the ACI/ASCC laser scan study in 2024 (top 1 from the total 26
dataset, validated with total station, and registration accuracy within 0.003’ (1mm), no filter was applied)
• One IFC reference model
• One CAD reference model
• One Architectural/Structural PDF Drawing
• ACI 117 – Tolerance document (partial, not for distribution)
• ACI 347 – Formwork for Concrete document (partial, not for distribution)
• ACI 303 – Architectural Cast-In-Place Concrete document (partial, not for distribution)

WHAT YOU RETURN
• The best deliverables you can produce in the most efficient way on your platform
• The interpretation of concrete tolerance: slab elevation, slab flatness and levelness (non-F number), wall location, wall plumbness, wall surface irregularity on your deliverable
• Description of your workflow
• The time it took from loading e57 to the end deliverables

DELIVERABLE REQUIREMENT
1. A deliverable to indicate the slab flatness and levelness (non-F-number)
1.1. If in a heat map format, the color needs to be ¼” increment
1.2. If in a heat map format, the color needs to be 1mm increment or less
1.3. Include contour lines, reference lines, background overlay, etc. for your best results if necessary
2. A deliverable to indicate the wall location tolerance
3. A deliverable to indicate the wall plumbness
4. A deliverable to indicate the wall surface void (bug holes) and irregularity
5. Deliverables can be combined if necessary
6. A document to explain your workflow to produce such deliverables, and the time taken from loading e57 file to end results.
