Technical tools and apps

There are lots of great web tools and apps that can help a Technical Officer perform his day-to-day duties. Here’s a list of some of our favourites, but if you have any other suggestions please let us know.

CDM Wizard

Strictly speaking the CDM wizard from the CITB helps to generate a construction phase health and safety plan, but it can also help to consider designers to consider health and safety issues. There is a desktop version, and also apps for IOS and Android.


The website also has guidance for smaller construction projects, including interactive guides for both the designer, the principal designer and a domestic client.

The Planning Portal

The Planning Portal has a Professional Portal with lots of useful resources, including downloads of the Building Regulations Approved Documents, and online applications for Building Control and Planning.

There’s also an interactive guide that shows how big you can make an extension without needing planning permission.

The LABC (Local Authority Building Control) website has even more resources including, a step-by-step checklist for level access thresholds, a Foundation Depth Calculator and a free Technical Manual that is also available for IOS and Android.
