CCTV design, access control layouts, and fire alarm drawings — all delivered in one coordinated package, permit-ready. The trial project alone was enough to convince us to sign a long-term contract.
// Frequently Asked Questions
Common Questions
What software does Nextegron use for AV and ELV design?
Nextegron uses AutoCAD, Revit, and BIM tools for engineering drawings. For AV systems we work with Crestron, Q-SYS, Dante, Extron, and Biamp. For ELV and building controls we work with KNX, DALI-2, BACnet, Lutron, and Dynalite.
How quickly can Nextegron deliver an AV or ELV design package?
Nextegron delivers most design packages within 48–72 hours for standard projects, and has completed 32-room AV design packages in under five days. For urgent requirements, a senior engineer responds to enquiries within 4 hours.
Are revisions included in the price?
Yes. Nextegron includes unlimited revisions until you are fully satisfied with the deliverable — there are no separate revision fees.
Does Nextegron offer a trial project before committing?
Yes. Nextegron offers an initial trial project at no commitment so you can evaluate design quality and delivery before entering a long-term engagement. This applies to AV, ELV, Security, ICT, and all other engineering disciplines.
