Labee Labs designs and builds software tools for the construction industry — working design calculators built on real code provisions, free for anyone in the field.
Labee Labs is a software studio founded by a professional engineer. We build digital tools that respect how construction actually works — submittals, code provisions, stamped drawings, and the coordination gaps between them.
Hardware calculators for lag screws, through-bolts, and post-installed concrete anchors — full yield-limit and Chapter 17 checks with printable calc sheets.
The complete AISC steel section database — searchable, filterable, unit-aware, and exportable for use in your own design workflows.
Professional sites and custom web applications for construction firms — from marketing pages to project dashboards, estimating tools, and client portals.
In a structure, the load path carries every force to the foundation. On a project, LoadPath carries every delegated design scope — equipment anchorage, seismic bracing, connections, cold-formed framing — from the design team to a qualified specialty engineer, and back as a coordinated, submittal-ready package.
Architects, EORs, and contractors define the delegated design item — drawings, specs, and seismic design criteria attached.
Qualified designers and specialty engineers pick up the scope, ask questions in-thread, and coordinate against the base design.
Calculations, details, and stamped documents come back as a complete delegated design submittal, ready for review.
Purpose-built workflows for nonstructural component anchorage in seismic regions — ASCE 7 design criteria captured up front, not discovered in review comments.
A vetted network of specialty engineers and designers, matched to scope, jurisdiction, and license requirements.
Every question, revision, and criteria change lives with the scope item — an auditable history from RFP to approved submittal.
Design teams get predictable delivery; specialty engineers get well-defined scopes with complete information. Everyone gets fewer resubmittals.
Working calculators we use ourselves, free for anyone in the industry. Every tool produces a clean, letter-size calculation sheet you can print or save to PDF.
Single-shear lag screw connections in wood or steel-to-wood — withdrawal, lateral yield modes, lead holes, spacing, and combined-load interaction.
Open the tool →Single or double shear bolted connections — wood yield modes plus bolt shear, tension, plate bearing, tearout, and shear-tension interaction.
Open the tool →Post-installed expansion anchors (KB-TZ2, Strong-Bolt® 2, Power-Stud®+ SD2) — tension and shear failure modes, group effects, edges, and seismic options.
Open the tool →Search, filter, and compare every AISC shape. Customize visible properties, apply advanced filters, and export your results.
Open the database →Everything in T-200 is free and always will be. If a calculator saved you a fee proposal's worth of time, a tip helps cover hosting and keeps new tools coming.
Whether you need a website, a custom tool, or engineering software for your firm — send over your scope and we'll respond within one business day.
