Structural Engineering in Arkansas: what governs your project

Northeast Arkansas falls within the New Madrid Seismic Zone, so structures near the Mississippi River corridor must be designed for significant seismic forces under the IBC and ASCE 7. Outside the seismic zone, wind loads generally govern lateral design. Expansive clays are present in parts of the state and require careful foundation design, while the soft alluvial soils of the eastern lowlands often push larger buildings onto deep foundations.

Permitting & plan check

Building permits and plan review are handled by city and county building departments, with larger cities such as Little Rock operating their own full permitting offices. The State Fire Marshal reviews certain occupancies, including schools and state-owned facilities. Projects should confirm the applicable building code edition with the local authority having jurisdiction before design begins.

Good to know

• Northeast Arkansas lies within the New Madrid Seismic Zone, one of the most active seismic areas in the central United States.
• Much of eastern Arkansas sits on the Mississippi Alluvial Plain, with deep, soft soils that commonly require deep foundations for larger structures.
• Arkansas spans IECC climate zones 3A and 4A, meaning commercial buildings must handle both significant cooling loads and winter heating.
