About Us

Life outside the tick box.


At the heart of the building and construction industry is the need to design buildings and infrastructure assets such that they can be built, operated, maintained and modified without harming anyone affected by such works. It’s all about success, client delight and pride in a job well done.

SID empowers professionals, specifically those working for clients, designers and principal designers to achieve legal compliance without compromising creativity. CDM2015 training is at the core, but our offering is so much more.

We empower by providing information, training and advice. By high level networking, collaborating and research across the construction sector we stay at the top of our game, so you can trust what we share with you. 

We are big fans of the GIRI Initiative, Project 13 and the Health in Construction Leadership Group.

We also love collaboration and work with, or recommend, selected professional organisations and groups because we love the high quality of what they do. We also signpost you to resources of interest. See our knowledge hub page for information.
