As-Built Surveys & Laser Scanning for Chicago Commercial Buildings

Chicago’s building stock ranges from historic downtown properties and office towers to large industrial, logistics, and manufacturing facilities across Chicagoland. GeoMaus provides measured building surveys, 3D laser scanning, as-built documentation, Scan-to-CAD, and Scan-to-BIM for projects where accurate existing conditions matter.

We serve Downtown Chicago and industrial corridors across Northern Illinois, including Rockford and Belvidere, supporting renovations, tenant build-outs, adaptive reuse, facility upgrades, and complex commercial projects.

Typical projects: Office Buildings | Industrial Facilities | Warehouses & Distribution | Tenant Build-Outs | Healthcare |  Manufacturing | Data Centers

The Problem

Chicago Projects Often Start With Incomplete Information

A renovation may begin with a set of drawings that no longer reflects the building. Tenants have changed layouts, mechanical systems have been modified, walls have moved, and years of alterations may never have made it onto the original plans.

That becomes especially important during Chicago tenant build-outs, industrial retrofits, and adaptive reuse projects.

GeoMaus captures your property as it exists today, providing architects, engineers, contractors, developers, facilities teams, and property managers with a verified existing-condition baseline before the next phase of work begins.

WHY CHICAGO

From Downtown Towers to Northern Illinois Industry

Chicago is a large and diverse commercial market, with active demand across office, industrial, retail, data center, and multifamily properties. CBRE’s 2026 outlook highlights continued demand for prime office space and significant activity across Chicago’s industrial and data center sectors.

The industrial footprint extends well beyond the city. Chicago’s I-80 and I-55 corridors, Joliet, O’Hare, the western suburbs, and the Fox Valley form a major network of logistics, manufacturing, and distribution properties. Recent market data shows substantial leasing and construction activity across these corridors.

At the same time, Chicago continues to adapt older buildings for new uses. Historic Loop properties are being considered for adaptive reuse, while existing commercial buildings are being renovated rather than replaced.

That mix creates very different survey requirements within the same region. GeoMaus supports projects from Downtown Chicago through Chicagoland and into Northern Illinois, including industrial areas around Rockford and Belvidere.

WHAT WE DELIVER

Existing-Condition Documentation for the Next Stage of Your Project

We work on buildings 50,000 sqft and above including data centers,, offices, warehouses, distribution centres, and multi-site portfolios where accurate documentation is non-negotiable.

Every deliverable is built from verified 3D laser scan data, captured within your facility’s security and operational protocols. Delivered in DWG, PDF, or Revit, whatever your engineering team already uses.

Measured Building Surveys - Geomaus Services

Measured Building Surveys

Up-to-date floor plans, elevations, sections, and existing-condition information for commercial, industrial, and historic properties where original drawings are missing, outdated, incomplete, or no longer reflect the building accurately.

Scan to CAD

Clean 2D as-built drawings produced from laser scan data, ready to hand directly to your architect, engineer, contractor, facilities manager, or property development team.

Scan to BIM Models - Geomaus Services

Scan to BIM

A working Revit model of your property as it exists today. Useful for warehouse expansions, industrial redevelopment, adaptive reuse, commercial renovations, MEP coordination, facility planning, asset management, and multi-site portfolios.

As-built Documentation

A complete record of your property's current physical conditions. Drawings and models your team can rely on for refurbishment, expansion, redevelopment, tenant improvements, compliance, asset management, and future capital projects.

MEP documentation - Geomaus Services

MEP documentation

Coordinated documentation of ductwork, piping, cable trays, electrical systems, refrigeration infrastructure, equipment, and other building services, captured where they actually exist rather than where outdated drawings suggest they should be.

Matterport 3D Virtual Tours - Dollhouse View -GeoMaus Service

Matterport 3D Virtual Tours

A walkable 3D model of your property that your team can explore remotely from a browser. Useful for facilities management, property operations, leasing, vendor coordination, remote teams, and portfolio documentation.

HOW IT WORKS

From First Call to Delivered Drawings

On every project, you’ll work directly with Michael Kiernan, GeoMaus’s founder, from the first call through to delivery. No project coordinators, no handoffs, no relayed messages. When something changes onsite or a deadline shifts, you’re speaking to the person who can make the call that day.

Michael Kiernan | CEO, Founder | GeoMaus
Michael Kiernan - Founder of GeoMaus
No account managers, no handoffs. When you need a decision, you're talking to the person who can make it.
1
The First Call - Straight to Michael
You'll spend 30 minutes on a call with me, not a salesperson. We'll talk through your building, your timeline, and what you actually need at the end. If your project isn't a fit for us, I'll tell you on that call and point you somewhere better.
2
Onsite - Built Around Your Operations
We plan every scan day around how your building runs. Out of hours for retail and hospitality, around shift changes for warehouses, security-cleared teams for sensitive sites. You'll know exactly who's onsite, when, and what they're doing.
3
Processing & Verification
Once we leave site, your data is processed by one team and quality-checked by another. By the time anything reaches you, two people have signed off on it. You don't have to be the quality control.
4
Delivery - Exactly How You Ordered It
You'll receive your drawings and models in whatever format your design team, facilities manager, or asset manager already works in. Revit, AutoCAD, PDF & Matterport. Plus a project handover call so nothing gets lost in translation.
