About RHEC
Technical rigour.
Grounded judgement.
Led by Chartered Engineer Ryan Hayden, the practice combines structural knowledge with hands-on mechanical and installation experience.
That cross-disciplinary background is especially valuable when a project sits between conventional categories—the unusual frame, one-off lifting device or temporary structure that needs an experienced eye and a practical way forward.
