Throw a Wrench In Your Plans
Tools for the trades,
built by a plumber.
Workforce development, done the practical way: a fourth-generation plumber using SI to build the tools the plumbing and mechanical trades actually need — free where it helps the most people, and built to make the next generation of tradespeople sharper, faster, and better equipped.
What we do
One brand, one mission: develop the workforce with SI-built tools.
Estimators, policy trackers, and practical apps — built from real trade experience and given away, because a sharper trade lifts everybody in it.
Regular writing on the trades, the codes, the technology, and where the work is headed — in plain language, from someone who has done the work.
Walkthroughs, demos, and tool tours — so you can see a tool work before you ever open it. The newest videos live in the Watch section below.
The tools
Everything below is a ConTech Consulting product, presented under the Throw a Wrench In Your Plans brand.
A free plumbing and mechanical estimator — build an estimate, print it, and get on with the job.
A state-by-state map of water-energy policy — what is enacted, what is pending, and what it means for the work.
The governed library of printable plumbing interface parts and field tools — safety-checked before a file ever reaches your printer.
The Ask John™ platform — SI code strategy, estimating, submittals, and scheduling — licensed as a company's own branded instance.
The field capture protocol for the trades — capture the work, build the labor record, own the data.
Ask John™ on Ray-Ban Meta glasses — hands-free TradesIP™ capture and voice code-strategy Q&A, free during the soft launch.
Watch
The tools, working — not just described.
Ask John™ portal walkthrough — a tour of the platform itself: code strategy answers, estimating, submittals, scheduling, and safety talks, as a working contractor would use them.
PlumbPrint™ library tour — problem, search, card, print. The screens are the real product; print files roll out part by part after review.
TradesIP™ protocol trailer — field capture, side by side: installation footage on the left, the portal labor record building in sync on the right. The public teaser; the full protocol lives behind the licensing NDA.
