Peter W. Hahn


Peter represents commercial contractors and project owners in all facets of a construction project, from procurement through dispute resolution. His substantial experience and understanding of the industry, as well as his knowledge of general business disputes, allow him to modify his approach for each client, carefully crafting a strategy to meet their individual needs and goals. 

His understanding of the construction industry allows him to advise clients-both public and private-through disputes and liability avoidance at every phase of a construction project, from the drafting and negotiation of initial contracts all the way through to post-project issues such as construction defect claims. He also brings a knowledge of construction reform law, allowing him to guide clients through the complex and evolving legislation that continues to impact the industry. In addition to drafting custom-made construction documents and advising clients on appropriate modifications to standard construction contracts, he has also represented clients through a variety of matters, including:

  • State and federal prevailing wage law, 
  • Mechanics’ liens, 
  • Project delivery methods, 
  • Payment and delivery performance bond claims, 
  • Publicly-bid projects, 
  • Change orders and directives, 
  • Differing site conditions, 
  • Delay and acceleration claims, 
  • Project safety concerns, 
  • Problems with coordination of work, and 
  • Construction defect claims.

Peter also remains active in construction-related organizations, allowing him to stay advised of developments that will impact the industry. He is a member of the Builders Exchange (BX) of Central Ohio, and a participant in the BX Rising Leaders Program. Additionally, he also is a member of the Associated Builders and Contractors of Central Ohio, the Columbus Bar Association’s Construction Law Committee and the American Bar Association’s Forum on the Construction Industry. Understanding the ever-changing developments, legislation and regulations around the construction industry allows Peter to provide his clients with unique insight and perspective, enabling them to mitigate their risk as they move forward.
