Laser Floor Flatness Survey
Summary
Freelancer Client is hiring: Laser Floor Flatness Survey.
Location: Remote
I have an existing 1,100 sq ft residential concrete slab that must meet the National Wood Flooring Association tolerance of 3/16" over 10 ft before I lay engineered hardwood. To pinpoint every dip and crown accurately, I need someone who can arrive with a calibrated horizontal rotary laser (or equivalent set-up) and document the slab’s flatness in detail.
A full laser sweep of the entire surface, recording elevations at a spacing tight enough to capture subtle variations.
A clear, professional report that highlights all low and high spots, includes elevation maps or grids, and states how far each variance falls outside the 3/16" guideline.
Practical recommendations—grinding, self-leveler, feather edging, etc.—so the slab can be brought into spec for engineered hardwood.
All findings referenced to NWFA requirements and the flooring manufacturer’s literature.
Skills: Project Management, Engineering, Report Writing, Civil Engineering, Data Analysis, Construction Engineering
Budget: $30–$250 USD

Here’s what I expect once you’re on site:
• A full laser sweep of the entire surface, recording elevations at a spacing tight enough to capture subtle variations.
• A clear, professional report that highlights all low and high spots, includes elevation maps or grids, and states how far each variance falls outside the 3/16" guideline.
• Practical recommendations—grinding, self-leveler, feather edging, etc.—so the slab can be brought into spec for engineered hardwood.
• All findings referenced to NWFA requirements and the flooring manufacturer’s literature.
You’ll probably be in and out in a single visit, but the measurement accuracy and clarity of the report are critical. If you’re an engineer or inspector who regularly verifies concrete flatness with laser equipment, I’d like to hear how you approach a job like this and see an example page or two from a past report.
