Planning a garage addition? You don’t always need a complicated set of drawings.

We recently helped a Dunlap project move forward using the builder’s existing drawings and hand sketches. We turned that information into a 3D model and a clear set of permit documents, showing how the new garage connects to the existing home.

Sometimes simple is the right answer. Our new case study explains how we matched the level of detail to the project’s needs.

Wondering what 3D laser scanning costs? The answer depends on your project, and knowing what affects the price can help you plan.

Our new guide covers the factors that shape a scanning estimate, including building size, complexity, site access, and the deliverables you need. It also includes a quick checklist to pull together before you request a quote.

Ever tried to picture a finished space from a set of floor plans? Renderings make that easy.

Architectural renderings let clients, contractors, and stakeholders see materials, lighting, and layouts before construction begins. At TWG, we build every rendering on laser-scanned data, so what you see reflects the real building, not guesses.

Curious how it works and where it helps most? Our new blog post walks through it.

Field conflicts during MEP coordination aren't inevitable—they're a sign you're working without accurate site data.

When you start with laser scanning, everything changes. Your coordinated model is built on actual site conditions, not what outdated drawings and error-prone hand measurements suggest. That means faster coordination, confident fabrication planning, and crews who get construction-ready documentation they can trust.

Check out our latest breakdown on how scan-to-BIM eliminates the guesswork during project planning.

Is Your Building Documentation Really Up to Date?

Many teams rely on photographs and drawing sets created for construction as their primary documentation. The problem? Photos don't show precise dimensions and change orders during construction affect the accuracy of construction drawings. By the time you realize the documentation is incomplete, you're already experiencing problems and delays.

This is where as-built documentation supported by 3D laser scanning transforms the picture. Instead of scattered measurements, you get complete information about spatial relationships, dimensions, and final conditions. Your teams can plan with confidence instead of from assumptions.

Whether you're documenting a completed project or managing facility records, accurate as-built documentation gives you the reliable information you need to plan.

Refurbishing the Pekin Dragon Sign

KSA Lighting & Controls needed to install new LED light strips on Pekin's scoreboard sign—but measuring a curved structure by hand can be error prone.

Instead, they used TWG's 3D laser scanning to capture the sign's exact outline in one session. No guesswork. Just verified dimensions they could use immediately for design and installation.

That's how refurbishing projects should work. Discover how laser scanning drives design precision. 👇️

Renovation over budget? Behind schedule?

It usually comes down to one thing: incomplete existing conditions data.

A design conflict nobody caught becomes an expensive mid-construction problem. Work stops. Contractors improvise. Change orders pile up.

The fix? Start from accurate, verified existing conditions before design even begins. Conflicts get caught early — when fixes are cheap. Contractors enter the field with complete information. Fewer surprises. Less rework. Better timelines.

We just published a breakdown of how accurate existing conditions documentation pays for itself.

Designing a theatre expansion? You need stakeholders to see the design before they approve it.

That's why Peoria Players Theatre chose TWG's laser scanning and photorealistic renderings for their new restroom addition. Instead of asking theatre leadership to interpret 2D drawings, we laser scanned the entire building and created Twinmotion renderings showing exactly how the addition would look — from multiple angles.

The result? Laser scanning and photorealistic rendering that brought the renovation concept to life. 👷‍♂️

Revit is more than a 3D drawing tool — it's a unified model where every wall, door, and mechanical system lives in the same digital space. Change something in one view and it updates everywhere automatically.

For renovation projects, that model is only as useful as the existing conditions behind it. TWG laser scans the site first so architects design from verified measurements — not assumptions about what's already there.

We just published a post breaking down what Revit modeling is and how it works with laser scanning. Give it a read 👇

BIM modeling — you've probably heard the term. But what does it actually mean for a construction project?

We just published a straightforward article breaking it down — what BIM is, how it differs from standard CAD drafting, and how TWG uses laser scan data to build coordinated Revit models that give project teams an accurate foundation to design and build from.
