LTN Engineering

LTN Engineering is a structural and civil engineering firm in Mankato, Minnesota, not a construction company, which makes it a useful resource for owner-builders and contractors who need stamped plans for a barndominium. The firm reports more than 35 years in business and holds Professional Engineer licensure in Minnesota, Iowa, Nebraska, Wisconsin, North Dakota, and South Dakota, with a working focus on Mankato, southern Minnesota, the Twin Cities, and the wider Upper Midwest. Structural services cover post-frame buildings, foundations, residential and industrial structures, renovations, facades, solar installations, and FEMA 361 storm shelters.

On the site-civil side, LTN handles site planning, topographic mapping, grading, utilities, ADA compliance, and construction staking, and the firm also offers construction administration and project management. Membership in the National Frame Building Association alongside ASCE, AISC, AWC, and ICC signals direct familiarity with post-frame design, the structural system behind most wood-framed barndominiums. For a barndominium project, that means one office can produce the engineered drawings a county building department requires and review the site work that precedes construction.

Contact is by phone or email from the Mankato office, weekdays 8am to 5pm.
