Accurate floor plans, as-built drawings, and existing conditions Revit models for data centers as well as hotels, industrial complexes, and offices. Built for the operational realities of live data centers: continuous uptime, high security, and zero tolerance for accidental disruption. Every project is run directly by Michael Kiernan, GeoMaus’s founder.
Typical projects: Existing data centers and hyperscale facilities, office buildings, hotels and restaurant. Single properties, brand portfolios, and global multi-site programmes.


Ashburn and the surrounding Loudoun County corridor host the densest concentration of data centers on Earth. From the legacy MAE-East peering infrastructure to the hyperscale campuses along the Dulles Technology Corridor, this region powers the internet.
That density creates unique challenges for facilities teams. A single inaccurate dimension in a server hall can cascade into MEP coordination failures, delayed permits, and millions in rework. When you’re planning whitespace expansion, cooling upgrades, or infrastructure retrofits, you can’t afford to work from outdated drawings.
GeoMaus understands the Ashburn ecosystem. We’ve surveyed operational colocation halls, active electrical rooms, and live cooling plants across Northern Virginia – all without a single minute of downtime. Whether you’re documenting one facility or a multi-site portfolio, Michael Kiernan handles every project directly.

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.

Up-to-date floor plans, elevations and sections for existing conditions data centers and other buildings where the original drawings are missing, outdated, or wrong.

Clean 2D as-built drawings produced from laser scan data, ready to hand straight to your architect, leasing team, or facilities manager the day they land.

A working Revit model of your facility as it actually is today, not as it was designed. Critical for capacity planning, infrastructure upgrades, and multi-site portfolio coordination.

A complete record of how your data center is built today. Drawings and models you can rely on for the next 20 years of capital planning, compliance, and asset management decisions.

Coordinated models of the ductwork, pipes, cable trays, and electrical systems running through your building, captured exactly where they actually sit, not where the design said they would be.

A walkable 3D model of your facility anyone on your team can explore from a browser - no software, no training, no site visit and is ideal solution for remote engineering teams and vendor coordination.
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.

Everything you need to know about our data center surveying workflow, accuracy, and deliverables.
Most enquiries get a same-day reply from Michael directly. If your project isn’t a fit for us, he’ll tell you on the call and point you somewhere better.
No sales calls, no automated drip sequences. Michael replies personally to every enquiry usually within a few hours.
