Great, found the site. It has listed at least one company my collegue has used.
This site is in Barnsley. We have a great deal of desk top info already as this site has alot of history being in a mined area. It's a new project for us on an existing college and I am still to get my teeth into it. Any new Geo investigation will be on a small scale and taylored around the existing info. There's some research for me to do yet before I can tender this element.
The engineering section to my company is relatively new. Working nationally I hope to establish regional relationships with companies including Geo investigators.
Thanks for the reply.
