Groundworks in readiness for the construction of the Stadium for Cornwall are due to begin next week.
Preparatory works at the Threemilestone site, near Truro, are starting just four months after Cornwall Council approved £3m of public funding towards the project.
The partners behind the Stadium for Cornwall - the Cornish Pirates, Truro City FC, Truro and Penwith College and GLL Ltd - have appointed Cormac Solutions to carry out the initial groundworks.
Excavation and drilling work will commence on August 13 for four weeks to confirm ground conditions. Once that work is complete, there will be testing and analysis of the soils and water, which will be reported on by October.
