AutoCAD drawings and BIM security models
Contractors build from drawings, not concepts. We produce coordinated, layered AutoCAD sets and BIM models that survive tender queries, site changes and as-built handover.
In short
BIM & AutoCAD Engineering — Production-ready AutoCAD security drawings and Revit BIM models at LOD 200/300, including device layouts, risers, details and clash coordination.
Service overview
Design intent is only as good as the drawings that carry it to site. We produce coordinated AutoCAD and BIM documentation to a consistent layer, block and titleblock standard so security packages read cleanly alongside architectural and MEP sets.
Models are used actively — clash detection against ceilings, structure and services, mounting-height verification, cable-route validation and camera field-of-view placement in 3D — so issues are resolved before installation, not during it.
Every package is issued with a revision history and drawing register, keeping consultants, contractors and clients working from a single controlled source.
What this service covers
Layered CAD sets
Consistent layers, blocks, title blocks and revision control.
BIM LOD 200/300
Revit security families coordinated with architecture and MEP.
Riser and detail sheets
Riser diagrams, mounting details and typical installation sheets.
Clash coordination
Device and containment clashes resolved before site.
Key capabilities
- AutoCAD security and ELV layouts to client CAD standards
- Revit / BIM modelling with security families and LOD-appropriate detail
- Clash detection and multi-discipline coordination
- Mounting details, riser diagrams, wiring schematics and typical details
- Drawing register, revision control and issue management
- As-built and record documentation on completion
Drawing discipline that holds up
Every drawing set carries a device schedule tied to the same tags used in the BOQ, so quantities, drawings and specification stay in agreement through revisions.
Deliverables
- Device layout drawings per floor or zone
- Riser diagrams and single-line schematics
- Mounting and installation detail sheets
- Revit models at agreed LOD with security families
- Revision-controlled drawing register
- Coordinated AutoCAD / BIM drawing set with full titleblock and revision history
- Typical detail and schematic sheets for installation
- Drawing register and clash / coordination report
Typical environments
Frequently asked questions
Which file formats do you deliver?
DWG, PDF and, where BIM is in scope, RVT and IFC exports.
Can you work to our CAD standard?
Yes. We adopt your layer, block and title block standard, or apply a documented one if none exists.
Do you produce as-built drawings?
Yes, as-builts can be produced from contractor red-line markups at project close.
