Experience
Over 30 years of private practice in construction law and construction litigation. Practice heavily focused on resolution of very large and complex construction disputes throughout the entire U.S. and internationally, including on many mega-projects and with alternative delivery systems, especially for design-build and PPP delivery methods.
Experience spans multiple projects each in many separate construction industry sectors: 1) road, bridge, interstate, and toll road infrastructure projects; 2) major / signature bridge projects (including segmental concrete bridges, suspension bridges, and cable-stayed bridges); 3) light rail commuter train and subway projects; 4) heavy-rail projects and the first U.S. high-speed rail project; 5) vertical construction projects (high-rise and low-rise, both private / commercial and public sector); 6) airport terminal, concourse, runway and taxiway projects; 7) major water infrastructure projects (Third Locks Expansion at the Panama Canal, largest U.S. dam raise project, and water treatment plants); 8) EPC / industrial projects (production facilities, petroleum refineries, high voltage transmission lines traversing an entire state); and 9) residential projects. For at least fourteen projects, the matters in dispute ranged from $100 million to over $1 billion.
A substantial portion of experience has been for very large delay, disruption, and productivity loss claims. Types of disputes have also included claims regarding: extra / additional work; liens and bonds; defective construction / defective design; post-design / construction structural failures; differing site conditions; supply-chain issues including tariffs and taxes; qui tam litigation / False Claims Act allegations; bid protests; performance defaults and project abandonment; business torts (fraud, negligent misrepresentation, tortious interference, civil conspiracy, conversion, R.I.C.O.); contested domestication of foreign country money judgment; consequential damages; cardinal change; adjoining property issues (structural damage, loss of value, trespass, nuisance); suspension and debarment proceedings. Additional experience with criminal investigations regarding material substitutions and billing practices; environmental investigations; OSHA investigations and citations; labor & employment claims and union grievances arising out of construction projects (discrimination, retaliation, hostile workplace, violation of collective bargaining agreement); and catastrophic personal injury / property damage claims from heavy civil construction projects.
Practice has included representation of industry participants with differing viewpoints, including design-builders, design / engineering firms, owners, developers, contractors, subcontractors and sureties. Representation has extended to all phases of legal services - from procurement (contract review, preparation and negotiation, and bid protests) to project counsel services for the development / investigation of claims to the prosecution / defense of disputes in all forms of dispute resolution, including appeals.
Beyond the nearly three decades of construction law / litigation experience, educational background is in construction management, with four years of construction work experience in the field.

Mediator Style & Process Preferences
Mediation is not a one-day event; it is a process that begins well before the mediation session and often continues afterward. Meaningful preparation is essential to successful resolution. Pre-mediation conferences with counsel, clients, insurance adjusters, and other key decision-makers are strongly encouraged as early as practicable to evaluate strengths, weaknesses, risks, costs, and realistic settlement parameters. Early exchange of substantiated demands, damages analyses, and other information necessary for informed negotiation is likewise encouraged to facilitate productive discussions and enable obtaining appropriate settlement authority.
Presentations in joint session are generally preferred, so long as they are respectful, factual and professional, because they allow decision-makers to hear the opposing party's perspective firsthand; however, mediations may also proceed without opening presentations when circumstances warrant or based on the parties' preferences. Depending on the needs of the parties and applicable ethical considerations, both facilitative and evaluative techniques may be employed. Mediations may be conducted in person, remotely, or in hybrid formats, with flexibility in scheduling to accommodate participants across jurisdictions, time zones, and other business demands.
Thorough preparation, attention to detail, persistence, and unwavering commitment to confidentiality characterize the mediation process. Considerable advance effort is devoted to understanding the dispute, contractual framework, underlying facts, and applicable legal principles. When a matter does not resolve on mediation day, involvement continues to assist the parties in exploring every reasonable path toward complete or partial resolution in the days, weeks, or months that may follow.

Familiar with and accustomed to online / virtual meeting platforms like Microsoft Teams and Zoom, among others.
