Timothy F. Hegarty, a Partner at Zetlin & De Chiara, is a construction lawyer who drafts and negotiates complex design and development agreements and resolves high-stakes construction disputes across the United States and internationally.
Mr. Hegarty’s practice spans construction transactions and disputes, including construction and development contracts, claims, arbitration and mediation, and surety law. He advises property owners, developers, institutional clients, lenders, private equity firms, owner’s representatives, architects, engineers, design consultants, design-builders, construction managers, general contractors, and trade contractors. He supports traditional delivery, construction management, design-build, integrated project delivery, and public-private partnerships.
A former civil engineer, Mr. Hegarty brings a keen ability to read and understand plans and specifications, providing a distinct advantage in risk allocation, claim evaluation, and dispute prevention and resolution.
He negotiates contracts, mitigates disputes that arise during design and construction, and resolves large construction claims through litigation, arbitration, and mediation. He has litigated construction cases in Federal and State Courts and advises clients from adjacent property and access license agreements through preconstruction, demolition, construction administration, and post-completion.
Representative matters include adjacent property and license issues for redevelopment; disputes involving change orders, extra work, additional services, liquidated damages, delays, lost productivity, acceleration, and inefficiency; and issues involving payment and performance bonds, surety, and mechanic’s liens. His work covers mixed-use commercial developments; luxury condominium and affordable residential communities; office buildings and universities; healthcare, hospitals, and pharmaceutical facilities; casinos; correctional facilities; and public projects.
Mr. Hegarty is an adjunct professor at Columbia University, where he has taught “Legal Issues in Building Construction” for more than fifteen years.
