A message from our founder
“Every project starts with one question: can the site team build from these drawings?”
I started Hashtech Consultancy in 2021 to be the BIM partner I would want to hire myself: one that understands how buildings actually go together on site, not just how they look in a model.
We coordinate early, check our work before it leaves our office and stay with you until handover. You deal with me and a small team who know your project inside out.
Thank you for considering Hashtech. I would be glad to hear about your next project.
