• About Us

    We are a nine-lawyer Construction Law boutique. Our senior partner, William Allensworth, helped found the Construction Law Section of the State Bar of Texas and was the founder and first Chairman of the Construction Law Section of the Travis County [Austin] Bar Association. All of our lawyers have devoted their careers to the practice of Construction Law, and we have handled countless construction disputes and helped negotiate and draft contracts on a wide variety of construction projects.


  • Scholarship

    Our firm has been deeply involved in establishing Construction Law as an area of academic and professional scholarship. Two of the members of our firm are Adjunct Law professors at the University of Texas School of Law, teaching courses in Construction Law and in Construction Litigation, and all of the firm’s attorneys author papers and speak at professional seminars on Construction Law.


  • Relationships

    Our clients include many of Central Texas’ most prominent architects, engineers, contractors, and specialty contractors, together with their insurers, and a number of owners (both public and private), developers and homebuilders.


Mission Statement

Since 1995, our mission has been to provide cost-effective legal services to the construction industry, from the negotiation and drafting of contracts to the mediation, litigation, and arbitration of construction disputes. In fulfilling that mission, we have grown to be one of the largest Austin-based construction law firms, representing clients throughout the State of Texas.
