The complete AEC software stack for small firms
6 min read Jun 2026
From structural calc to project management, here's the toolkit every small firm should consider.
Build the stack around one core tool
A small firm does not need ten tools — it needs three or four that talk to each other. Start from the core deliverable (structural calculations) and build outward only as far as it pays for itself.
The core layers
- Structural calculation software. The non-negotiable. Choose one with current code libraries and live support.
- CAD / BIM authoring. Match your market: many structural firms still run 2D CAD efficiently alongside a BIM seat for larger projects.
- Project and document management. A single shared folder structure with version control beats five disconnected tools.
- Invoicing and time tracking. Even a lightweight tool keeps utilization honest.
What to skip early
- AI assistants until your volume justifies the license.
- Separate takeoff software if your CAD tool exports quantities.
- Custom integrations — favor native connectors before paying for middleware.
A budget benchmark
A three-person structural firm can run a full, professional stack for under $12,000 per year by applying member discounts and avoiding redundant seats. The same stack at list price often exceeds $20,000 — the difference is not the tools, it is the pricing you accept.
