These plans provide conceptual information. Periodic changes in the National Design Specifications for Wood Construction, changes in building materials, snow load variations and the serious impact of deviations from the plans make it imperative that professional services be utilized to tailor these plans for your situation. Suggested services include but are not limited to: structural design, assurance of compliance with codes and regulations, supervision of site selection and construction, and provision for utilities, waste management, and access. North Dakota State University, the Midwest Plan Service, the United States Department of Agriculture, and none of the cooperating Land-Grant Universities warranty these plans.
