Differential elevation can develop when one slab settles or heaves, supporting soils expand or contract, tree roots displace the slab, support beneath the pavement is disturbed, or earlier repairs alter adjoining surface elevations. Field measurements can document the height, location, and geometry of the change. Photographs, soil and drainage conditions, repair history, nearby vegetation, and evidence below the slab can help assess which mechanisms are most consistent with the observed displacement.
Post-incident documentation can include measurements of elevation differences, joint widths, running and cross-slopes, cracks, depressions, surface wear, and the surrounding route, together with photographs or video showing the condition from multiple viewpoints and with appropriate scale. Those observations document the sidewalk when inspected; they do not necessarily establish that the same condition existed at the time of an earlier incident. Contemporaneous photographs or video, prior inspections, repair records, earlier measurements, and evidence of later alterations can help reconstruct how the condition changed before or after the event.
Water and poor drainage can change moisture conditions in the soils and materials supporting a sidewalk and, depending on the site, contribute to erosion, loss of support, frost effects, or localized movement. Poor grading can also allow water to pond along the walking surface or repeatedly move through the same area. Elevations, drainage paths, staining, soil or subgrade conditions, joint conditions, and observed movement can help assess whether water-related conditions contributed to the deterioration.
Running or longitudinal slope describes the change in elevation along the direction of travel, while cross-slope measures the inclination across the walking surface. Localized settlement, previous repairs, driveway crossings, grading, or construction irregularities can produce geometry that differs from adjoining sidewalk sections. Field measurements document the actual condition and can be compared with design documents and any accessibility or construction requirements applicable to the location.
Prepares clear, well-supported expert reports outlining methodology, analysis, findings, and opinions.
Provide Deposition Testimony
Explains findings and opinions under oath and responds to questioning during deposition testimony.
Testify in Court
Presents specialized findings and opinions clearly to judges, juries, arbitrators, or other decision-makers.
Repair records may show that cracking, settlement, displacement, or another condition had previously been identified at the same location. Grinding, patching, slab replacement, overlays, or repeated work can also alter the geometry of adjoining surfaces. Comparing repair records and historical photographs with later measurements can help reconstruct whether the disputed condition appears new, recurring, progressive, or modified by previous work.
