Most lawsuits against engineers and architects don’t start with “bad work.”
They usually start with something like:
- a project goes sideways
- money gets lost
- timelines blow up
- people get frustrated
…and then everyone starts looking for someone to blame.
Here are the top 5 reasons we see A&E firms pulled into lawsuits (even really good firms).
1) A Detail Gets Missed (Errors & Omissions)
This is the classic one.
A small plan mistake can become a big deal fast:
- a wrong dimension
- a missing structural note
- inconsistent sheets
- a spec that creates a downstream issue
And once construction begins, fixing it gets expensive — which is when attorneys show up.
2) Someone Wants to Recover Delay Costs
Delays are one of the fastest ways a project turns adversarial.
Even if you didn’t cause the delay, it’s common for:
- owners
- GCs
- subs
to point fingers.
If an RFI sits too long, plans change late, or revisions keep coming… design professionals often get pulled into the mess.
3) Construction Admin Turns Into “You Should’ve Caught This”
This happens all the time.
A lot of claims come from jobsite conversations like:
- “You approved this.”
- “You should’ve rejected that.”
- “You were responsible for inspection.”
- “You signed off.”
But here’s the issue: many people on the project assume the engineer/architect is the quality control department — even when your contract doesn’t say that.
4) Scope Creep + Informal Advice
This one is sneaky.
It starts with “can you just take a quick look at this?”
Then there’s a short email. Or a quick call. Or a text.
Later on… something fails, something delays, or something costs money — and that “informal advice” becomes a formal allegation.
If it isn’t in the contract and it isn’t documented properly, it’s a lawsuit waiting to happen.
5) The Project Type Is Simply High-Lawsuit Risk
Some project types just attract litigation — even when the work is solid.
Examples:
- condos / multifamily (especially for-sale)
- structural and stamped design
- hillside work
- pools, retaining walls
- renovations (unknown conditions)
These projects have more complexity and more parties — which usually means more disputes.
