About Andrew

Andrew Guess is a construction attorney, advising owners, general contractors, major trade contractors, design professionals, and suppliers. He works with clients to achieve their goals on public and private construction and development projects through deliberate contract drafting, pragmatic project closeout negotiations, and result-focused litigation. Andrew represents clients in claims related to delay and impact, mechanic’s liens, payment disputes, bid protests, and public and private bond issues. He is experienced in drafting and reviewing construction contracts, including master service agreements, subcontracts and purchase order agreements, change orders and contract modifications, tolling agreements, and project closeout agreements.

Andrew’s practice is guided by his experience as a construction project engineer. In this capacity, before earning his law degree, he helped manage the development and construction of large-scale multifamily projects. Effective construction litigation requires an understanding of project planning and estimation, preconstruction, execution, and project closeout. Andrew’s experience in construction management has provided him with a deep understanding of how business issues such as cash flow, labor concerns, supply-chain management, technology, safety, and overhead costs are as critical at the project level as they are during contract negotiations and litigation.
