Evalation Lab

Now with Trex RainEscape® — design under-deck drainage systems and get full material pricing automatically. Built for contractors who work outside.

Evalation Lab is the design and estimating tool built for outdoor living contractors — decks, pergolas, concrete flatwork, and retaining structures — all in one app on your iPad or iPhone.

DESIGN ON THE JOB SITE Draw your deck or structure to scale directly on the canvas. Snap walls, draw deck surfaces, place footings, railings, and stairs. The 3D view updates in real time so you can walk clients through the design before a single board is cut.

STRUCTURAL CALCULATIONS BUILT IN Evalation Lab runs IRC-compliant beam sizing, joist spans, and footing loads as you design. Every structural result is documented and printable.

PROFESSIONAL BLUEPRINTS — INSTANTLY Generate a full permit-ready blueprint package as a PDF: plan view, section cuts, framing layout, material schedule, and code notes. No CAD software needed.

ACCURATE ESTIMATES IN SECONDS Material takeoffs and labor costs are calculated automatically from your design. Set your own pricing, margins, and framing system — Fortress Evolution, Safco Buildex (Forever Frame®), or Traditional Lumber — and the estimate updates live.

TREX RAINESCAPE® DRAINAGE SYSTEM Add the Trex RainEscape® under-deck drainage system to any deck surface with a single toggle. The app calculates trough count, drain locations, butyl tape rolls, and hidden gutter linear footage per bay — with full line-item pricing in the estimate.
