Representative Experience

Since joining the firm shortly after its founding in 1986, Mr. Hanson has represented construction contractors, owners, trade and specialty subcontractors, sureties and design professionals involving significant claims for delays, acceleration, inefficiencies, changes, differing site conditions, defective design, and in default and convenience terminations.

Advice and counsel on government contract matters has become a major part of Mr. Hanson’s practice, including false claims allegations and investigations related to project progress submissions; Buy America obligations; Nationality, Source and Origin requirements; and small business set aside regulations; and issues associated with prime and subcontract agreements in the energy services industry involving the Federal Government or state or local government entities.

Representative projects have included large, complex federal and federally-funded works in the U.S. and overseas in heavy civil, nuclear, building and institutional, lock and dam, bridge, commercial, industrial, power generation, tunneling, process plant, telecommunications, water/wastewater treatment, environmental remediation, and aerospace and aviation construction. Mr. Hanson has litigated in federal and state courts, the Boards of Contract Appeals and in domestic and international arbitrations involving both government and private contracting parties, and has successfully resolved such claims through mediation.

Mr. Hanson has been listed in Chambers, USA as among America’s Leading Lawyers in Construction, and in Best Lawyers in America in Construction and Alternative Dispute Resolution.
