What is a latent condition in a construction contract?
Last reviewed July 5, 2026
A latent condition is an unforeseen issue on site that wasn't obvious during the pre-construction phase. It could be hidden rock or contaminated soil. These conditions can affect costs and timelines, so they usually need to be managed under the contract terms for variations.
Key points
- Unforeseen site issues.
- Not apparent during inspections.
- Can impact costs and timelines.
Latent conditions can create problems if they arise during the project. They often need a formal process to assess the impact and claim for variations. Document everything and follow the contract procedures to make sure you're covered.
