Local conditions
Forensic conditions in Maricopa County
Maricopa County's combination of expansive desert soils, extreme summer heat, and one of the fastest-growing construction pipelines in the United States creates conditions where distress in concrete, foundations, and pavements is not uncommon. Reactive soils common to the Sonoran Desert basin can shift with seasonal moisture variation, putting slabs, footings, and flatwork under stresses that may not appear until years after construction. When distress occurs — whether it is pavement delamination on a commercial site, foundation cracking in a tilt-up structure, or settlement in a parking structure — the investigation must be methodical and defensible from the first site visit forward. Our Phoenix-area hub dispatches ACI- and NICET-certified field technicians for evidence preservation, concrete coring, pavement sampling, and soil sampling. Laboratory analysis is conducted under a documented quality system with full chain-of-custody protocols. Licensed engineers are engaged for the technical evaluation and, where required, expert opinion and testimony.
Maricopa County soils frequently include caliche layers and expansive clay pockets that can influence foundation performance and make post-distress borings and sampling essential to distinguishing material failures from subgrade-related causes. Arizona's sustained high temperatures during summer months also raise questions about concrete placement conditions and curing histories that forensic investigators commonly need to reconstruct.
FAQ · Maricopa County
What does chain of custody mean in a forensic investigation, and why does it matter for our Maricopa County project?
Chain of custody is a documented record of who collected each sample, how it was stored, transferred, and tested. In litigation or dispute resolution, opposing counsel will scrutinize every gap in that record. Our technicians label, seal, and log cores and samples at the time of collection, and the laboratory receives them under a continuous custody record, so the physical evidence remains defensible from field to report.
What pavement distress conditions do you investigate, and which ASTM methods apply to sampling and analysis?
We investigate delamination, reflective cracking, premature surface raveling, and structural failures in asphalt and concrete pavement. Field sampling follows ASTM D5361 for asphalt cores and ASTM C42 for concrete cores. Laboratory analysis can include gradation, asphalt content, air void structure, and compressive or splitting tensile strength — selected based on the distress mode and the questions the engineer of record needs answered.
Can your technicians extract cores from post-tensioned slabs, which are common in Maricopa County commercial construction?
Yes. Post-tensioned slab coring requires locating tendons before cutting to avoid severing tensioned cables, which would cause immediate structural and safety consequences. Our technicians use ground-penetrating radar (GPR) scanning to map tendon layout prior to any core extraction. Core locations and GPR findings are documented photographically and included in the field evidence package delivered to the licensed engineer performing the evaluation.
Which office covers forensic in Maricopa County, AZ?
