Lloyd Worrall BIM Objects

Our generic Interspec Doorset COBie compliant BIM objects are free to download from the links below. Available in user-friendly Revit format, our Interspec doorset components have been created to simplify the specification process and assist the user when placing the BIM components. Several additional features and user selectable tick boxes are included:


Our doorset BIM objects are available in both single and double swing variations. A 3D swing zone has also been included to allow users to visually see the swing zone and assist with clash detection.

Fire Rating

A range of fire rated options are available. Choosing a fire rated door will automatically impact on the door leaf thickness and will also add the relevant fire signage and door closer.

Acoustic Rating

We also offer a range of acoustic options. Choosing an acoustic rated door will automatically impact on the door leaf thickness.

Ironmongery Sets

Our Interspec Doorset BIM objects are the first of their kind to offer user selectable ironmongery sets. Simply select your desired ironmongery set based on the purpose of the space.

Architraves, Drop Seals and Extension Linings

Our BIM objects also have several useful features for finishing off and scheduling your doors. Tick box options allow architrave detail to be added around the door frame. Tick boxes for drop seals and extension linings are activated when the door is set-up in a particular way.


The range also comes complete with a Materials Library for the following elements: Glazing bead material, frame material, door facing material and door edge lipping material.
