Construction tech that survives a real job site

Vendor demos and benchmark theater do not survive contact with mud, inspectors, or a coordination meeting that runs long. This site is the third option: tools and notes from someone who has pulled wire, coordinated models, and shipped automation that actually stayed in production.

Start with the free calculators

Fifteen browser-only tools – NEC wire sizing, voltage drop, conduit fill, box fill, load calcs, concrete, drywall, and more. They run entirely on your phone with no signal, cite the code section behind every result, and never ask for an account. **Most used on site:** – NEC Wire Size Calculator – ampacity from Table 310.16 plus voltage-drop check – Voltage Drop Calculator – 3% branch / 5% total per NEC 210.19(A) – Conduit Fill Calculator – Chapter 9 Table 1 for EMT, PVC, and RMC – Electrical Load Calculator – residential service sizing per NEC Article 220 Browse all calculators →

Honest reviews and field notes

AI tools, BIM software, clamp meters, and layout gear – tested against workflows that have to close by Friday. When something does not earn its keep, this site says so. When it does, you get the specific jobs where it wins. Read the blog for teardowns, worked examples, and coordination habits that reduced rework on real projects.

Guides and model review

Paid downloads fund the free tools. The NEC 2023 Quick Reference PDF ($7) packs ampacity and conduit-fill tables for a tool bag. For federated-model headaches, the BIM Clash Audit ($1,250) is a fixed-price independent review: prioritized report, top-10 fix list, and a 30-minute walkthrough.
