Robert S. Marconi


Since joining Ashbaugh Beal in 1989, my practice has been devoted to construction law and litigation, with a focus on public and private contracts, bid disputes and claim and dispute resolution. I’ve been the Chair of the firm’s Construction Law Group since 1999.

I’ve helped clients resolve construction disputes throughout the Western United States and have successfully handled multi-million dollar claims against a variety of public and private owners. My practice emphasizes mediation and alternative dispute resolution. I regularly conduct seminars and presentations on a variety of construction-related topics.

In city, state and federal projects, I’ve successfully handled hundreds of bid disputes that have resulted in millions of dollars of work awarded to my clients. Recently, I successfully defended a client’s $130,000,000 bid and another client’s $200,000,000 bid against two bid protests on two major public projects.

I am extremely active in construction industry trade associations, including AGC of Washington and NUCA of Washington. I am a board member of the AGC of Washington’s Education Foundation and NUCA. I am also the Chair of NUCA’s Legislative Committee. I am a past board member of the AGC of Washington.

I have handled hundreds of construction issues and disputes, and enjoy working with clients to help solve their problems quickly and effectively. And if litigation is required, I have the tenacity and experience to get great results.
