TL;DR
An elevation survey is the floor-level mapping a foundation contractor or engineer performs with a zip level or rotary laser, recording heights at a grid of points across the slab or framed floor to quantify how far and where a structure has settled. The readings become a contour-style map that distinguishes original construction tolerance from active movement and pinpoints where piers are needed.
What it means
An elevation survey is the floor-level mapping a foundation contractor or engineer performs with a zip level or rotary laser, recording heights at a grid of points across the slab or framed floor to quantify how far and where a structure has settled. The readings become a contour-style map that distinguishes original construction tolerance from active movement and pinpoints where piers are needed. Repeating the survey after underpinning documents how much lift was recovered.
