When Clients Ignore Advice: Lessons from Case History #2

In the latest episode of the GBA Podcast’s Case History series, hosts Elizabeth Brown, P.E. (JLT Consultants), and Abi Corbett (SME) explore a cautionary real-world scenario that underscores a central truth for geoprofessional consultants: risk often increases when sound engineering judgment is dismissed.

The episode examines GBA Case History #2, involving a geotechnical investigation for a custom home built along the flank of a ridge. The GBA member firm identified expansive clay soils and provided clear recommendations to mitigate potential damage, including avoiding slab-on-grade construction and implementing proper drainage controls. However, the project proceeded under a handshake agreement, and critical guidance was not followed.

As Brown notes, the situation ultimately resulted in preventable failure: “The builder would create a risk of significant damage if it opted for a slab on grade basement floor.” That risk became reality when the basement experienced cracking, buckling, and water infiltration shortly after construction.

The discussion brings the case to life with practical insights, including the risks associated with residential projects, the importance of written agreements, and how overlooking construction-phase observation can leave firms exposed. As Corbett puts it, “Ignoring your geotechnical engineer is… pretty much a terrible idea.”

Rather than simply revisiting what went wrong, the hosts emphasize actionable lessons geoprofessionals can apply immediately—from identifying high-risk clients to reinforcing “confirmation-dependent recommendations” and knowing when it may be prudent to settle disputes and move forward.

This episode offers a valuable reminder that even routine projects can evolve into high-risk situations without proper controls, documentation, and client alignment.
