Aggregate Expert Witness & Litigation Support

Aggregate Consulting, LLC provides expert witness and litigation support services for legal matters involving aggregate mining, mineral reserves, royalty disputes, and construction materials operations. Led by John M. Pitts, Jr. — with over 36 years of direct ownership, design, construction, and operational experience — the firm offers attorneys and their clients technically grounded, credible, and independent analysis rooted in real-world mining practice.

Whether your case involves a royalty dispute, a contested reserve valuation, an eminent domain proceeding, alleged operational negligence, or other construction materials litigation, our expert analysis provides the substantive foundation needed to support or challenge technical claims.

Cases We Support as an Aggregate Expert Witness

Mineral Rights & Royalty Disputes

Disagreements over royalty calculations, underpayment claims, lease interpretation, and production accounting are among the most technically complex disputes in aggregate and mining law. We provide independent analysis of production records, lease terms, tonnage calculations, and reserve data to establish what was owed — and what was paid. (See Royalty & Lease Advisory for the standalone royalty practice.)

Eminent Domain & Condemnation Proceedings

When aggregate-bearing land is subject to condemnation or a taking, accurate reserve valuation is critical to establishing just compensation. We provide defensible, data-backed reserve estimates — including 3D GPS/GIS modeling and, where the geology of the deposit is in dispute, geophysical interpretation by consulting geologist and geophysicist David Hale — to support landowners, operators, or government entities in determining the true economic value of mineral assets.

Deposit Acquisition & Purchase Disputes

Disputes arising from the acquisition or sale of aggregate properties often hinge on whether reserve estimates and due diligence representations were accurate. We provide technical review of pre-transaction reserve reports, drilling data, and site assessments to evaluate whether disclosed information met professional standards. (See Due Diligence for Quarry and Aggregate Acquisitions for the standalone pre-acquisition practice.)

Operational Negligence & Standard of Care

Claims involving alleged negligence in plant design, dredge operations, production management, or safety practices require a qualified expert who has actually operated these facilities. With decades of direct operational experience across sand, gravel, crushed stone, and dredge-based sites, we are positioned to evaluate whether industry-standard practices were followed.

Lease & Contract Performance Disputes

Mining lease disputes frequently involve questions of whether operations were conducted in a workmanlike manner, whether reasonable production was achieved, or whether a lessee fulfilled their obligations. We evaluate operational records, production data, and site conditions against applicable industry standards.
