Built for AEC.

You shouldn't be wasting time on tasks a computer can handle.

Valley CTC automates the grind of AEC work — compliance checking, specification writing, cost estimating — so you can focus on the work that actually needs your expertise.

Seriatim

Free Revit Plugin — Automatic Viewport Numbering
Automatically numbers all Revit viewports across every sheet — left to right, top to bottom — so you never have to worry about view numbering again.

For Revit versions 2025 & 2026

Revisa

AI Construction Drawing Reviewer

Reviewing a project against the Building Code is one of the most time-consuming — and high-stakes — tasks in any design workflow. Review changes that. Upload your project documentation and let our AI reviewer cross-reference it against the current Building Code, flagging potential compliance issues and drawing completeness before they become costly problems. Whether you're in early design or heading toward permit submission, Review gives your team a faster, more reliable second set of eyes — every time.

Speq

AI Specification Generator

Writing specifications is tedious. It doesn't have to be. We have created an AI to generate accurate, project-specific MasterFormat specifications based on your project parameters — in a fraction of the time it would take manually. Output is delivered as a clean, formatted Word document ready for your review and submission. Less time writing specs means more time refining the design that actually matters.

Appr-AI-se

AI Integrated Estimator

Estimating is never just about numbers — it's about understanding what you don't know yet. Appr-AI-se generates detailed trade-level cost breakdowns while simultaneously surfacing risk factors that could affect your bottom line. It's designed for early-stage budgeting and client conversations, giving teams the confidence to commit to a direction without waiting for a full quantity takeoff. Know your numbers. Know your risks. Move forward.

Schema

AI Structural Member Sizer

Early design decisions have structural implications — and waiting on a structural engineer for every preliminary sizing question slows momentum. Schema gives your team rapid structural member sizing guidance referenced against CSA and NBCC standards, right when you need it. It's not a replacement for your structural engineer — it's the tool that makes your conversations with them faster and more informed.
