What we investigate in Grand Forks
Grand Forks measures loss against the Red River of the North and the April 1997 flood that emptied most of the city, still the reference point for what water, frost, and soft lakebed clay can do to a building here. We document what actually failed, and a licensed engineer responds within 24 hours with no travel charges.
The conditions we see in Grand Forks
The Red River flows north across a flat glacial-lake plain, so downstream ice and frozen ground back the spring melt up into the city. The 1997 flood crested at 54.35 feet, forced the evacuation of roughly 50,000 people from Grand Forks and East Grand Forks, and ran into the billions in damage. Deep frost, near 6 to 7 feet, with FEMA-rated cold-wave and ice-storm exposure, heaves footings and loads roofs through a long winter.
The ground itself moves. Grand Forks sits on Lake Agassiz lakebed, and the Brenna Formation beneath it is a soft, highly plastic glacio-lacustrine clay the North Dakota Geological Survey flags as poor foundation material, with shrink-swell movement and low bearing capacity. The historic riverfront downtown is largely pre-1930 brick and masonry, hit hard in 1997, ringed by wood-frame housing and post-flood rebuilding on that same clay over deep frost.
How we help in Grand Forks
The evaluations Grand Forks cases usually call for
- Foundation, frost, and lakebed-clay evaluation
A cracked wall, a heaved slab, or a separated footing here can trace to deep frost, to shrink-swell in the soft Brenna Formation clay, to flood saturation, or to a construction defect. Our licensed engineers evaluate the structure and how the ground and frost behaved together, then document which cause is responsible.
Our structural engineering services- Flood and water loss investigation
After a Red River flood, an ice-related loss, or a plumbing failure, we determine what the water did to the foundation, framing, and finishes, and whether the damage traces to the flood, a pre-existing condition, or a defect. Each conclusion rests on the physical evidence at the property.

Fire origin & cause
Fire origin and cause in Grand Forks
As the 1997 flood peaked, fire broke out April 19 in the downtown Security Building and spread across three blocks, damaging or destroying eleven historic structures while hydrant pressure failed and crews fought it standing in floodwater. Aged masonry and a heating season that keeps furnaces, wood stoves, and space heaters running for months still shape fire risk here, and proving which system failed takes a real investigation.
Our NAFI-certified investigators work to NFPA 921. We examine the scene methodically, trace burn patterns back to the area of origin, and evaluate the heating, electrical, and mechanical systems to separate an accidental cause from an incendiary one. We preserve the evidence early, document the finding, and testify to it in deposition or at trial when the loss is contested.
Fires we investigate
- Residential and commercial fires
- Heating-system fires
- Electrical and appliance fires
- Historic masonry building fires
- Industrial fires and explosions
Common questions
Forensic engineering in Grand Forks, North Dakota
A different question about your case? An engineer, not a call center, answers within 24 hours.
Is foundation movement in Grand Forks from frost or from the clay?
It can be either, and often both. Deep frost and the soft, highly plastic Brenna Formation lakebed clay each move footings. We evaluate the crack pattern and the site conditions to determine the actual cause rather than assume it.
Can you assess flood damage after the water recedes?
Yes. Much of the structural evidence remains after a Red River flood. We evaluate the foundation, framing, and finishes to document what the flood caused and separate it from any pre-existing condition or defect.
Do you charge travel to reach Grand Forks?
No. We work Grand Forks-area cases from our Omaha lab and Los Angeles office with no travel charges, and a licensed engineer responds within 24 hours.
