IT Guide for Architecture Firms: Revit Specs and Backup

A small architecture firm needs four things from its IT: workstations that meet Autodesk’s published requirements for the model sizes you actually work on, a home for project files that suits how Revit shares work, backups that cover both live projects and the closed-project archive, and tidy control of licenses and logins. This guide covers each one with the vendor’s own numbers, then gives you a checklist and questions to ask any IT provider.

The Software and Hardware a Design Studio Runs

Most small studios run some mix of the following. Each one places a different demand on the computer and the network.

Tool	What it is used for	What it demands
Autodesk Revit	Building information modeling (BIM), a 3D model that also produces the drawings	Memory, fast single-core processor speed, fast local storage
Autodesk AutoCAD	2D drafting and detailing	Moderate, more for 3D and 4K displays
SketchUp, Rhino	Concept modeling	Graphics card
Rendering software	Still images, animations, real-time walkthroughs	Graphics card memory above all
Bluebeam Revu, Adobe Creative Cloud	PDF markups, presentations, boards	Memory, screen space
Microsoft 365 or Google Workspace	Email, calendars, general documents	A well secured account for every person
Large-format plotter (HP DesignJet, Canon imagePROGRAF and similar)	Check sets and presentation prints	A wired network connection and current drivers

What Workstation Specs Does Revit Actually Need?

Autodesk publishes three hardware tiers for Revit and ties each one to a model size. These figures come from Autodesk’s system requirements for Revit 2027, checked in September 2026.

Autodesk tier	Memory (RAM)	Model size Autodesk says it usually handles	Graphics card memory
Minimum (entry level)	16 GB	A single model up to about 300 MB on disk	4 GB
Value (balanced)	32 GB or more	About 600 MB	6 GB
Performance (large, complex models)	64 GB or more	About 1 GB	8 GB

Points that apply to every tier:

• Windows 11, 64-bit. Revit 2027 does not list Windows 10. If any design machine still runs it, read the Windows 10 end of support guide before your next Autodesk upgrade.
• Processor. Autodesk asks for an Intel or AMD processor with a base speed of 2 GHz or higher and recommends the highest single-core base clock speed you can get. Revit uses multiple cores for many tasks, but a very high core count with a slow clock speed is the wrong trade for modeling work.
• Storage. 30 GB for the install, and Autodesk recommends 100 GB free for temporary files. A solid state drive (SSD) is the practical choice.
• Graphics. A DirectX 11 capable card with Shader Model 5.

How to use the table: open the project folder, sort by size, and look at your largest .rvt files, including linked consultant models that load alongside yours. Buy for that size plus growth over the life of the machine. Autodesk notes that models vary, so treat the figures as a starting point.

What about AutoCAD?

AutoCAD is lighter. Autodesk’s system requirements for AutoCAD 2027 list:

	Basic	Recommended
Processor	2.5 to 2.9 GHz, 8 logical cores	3+ GHz base, 4+ GHz turbo
Memory	16 GB	32 GB
Graphics card	2 GB, DirectX 11	8 GB, DirectX 12
Disk	10 GB, SSD suggested	Same

AutoCAD 2027 also requires 64-bit Windows 11, and Autodesk notes that DirectX 12 with Feature Level 12_0 is required for the “Fast” visual styles.

And rendering?

Rendering is where the graphics card matters most. GPU and real-time renderers publish their own requirements, and they are usually well above Revit’s. Check the current requirements page for the renderer you use before choosing a card, and size the card’s memory to your heaviest scene. If only one or two people render, it is often more sensible to build one strong rendering machine than to buy a high-end card for every desk.

Where Should Project Files Live?

This is the decision that causes the most trouble, because Revit’s multi-user feature (called worksharing, where several people work in one central model) was designed for a local network.

Autodesk addresses this directly in its article on using cloud-synced services with Revit files. Its short answer to whether file-based worksharing works on Dropbox, OneDrive, SharePoint, Google Drive, or Egnyte the way it does on a local network is no. The problems it lists include corruption of the central model and lost work when two people synchronize at the same time.

That leaves three sound patterns:

Option	Fits	Trade-offs
File server or NAS (network-attached storage, a small storage appliance) in the office	Everyone works in the office on a wired network	Needs its own backup and secure remote access
Revit Cloud Worksharing (Autodesk’s paid cloud collaboration service)	Hybrid staff, outside consultants in the same model	Per-user subscription cost. Autodesk says to allow local disk space of three times the size of the cloud workshared models each user opens
SharePoint or OneDrive	Everything that is not a live workshared model: PDFs, specs, contracts, images, single-user files	Not for central models

For archives in Microsoft 365, the limits are generous but real. Microsoft’s OneDrive and SharePoint limits allow files up to 250 GB, and Microsoft recommends syncing no more than 300,000 items in total for best performance. A long-running firm’s archive can pass that count, so archive libraries are better left online than synced to every laptop. The SharePoint guide explains how to structure libraries.

People who need files from home or a job site should come in through a secured method, not an open port on the router. The options are covered in secure remote access for small businesses.

Plotters and the Office Network

• Wire the design desks. Opening and synchronizing large models over Wi-Fi is slow and uneven. Gigabit Ethernet to each workstation is the baseline. Faster links between the server or NAS and the network switch help when several people sync at once.
• Treat the plotter as a computer. Give it a wired connection and a reserved network address, install the manufacturer’s current driver, update its firmware, and change the default administrator password.
• Keep guests separate. Visitors and personal phones belong on a guest network that cannot reach the server or the plotter. See network segmentation.

Licensing Housekeeping

Autodesk subscriptions are assigned to individual people by an administrator in Autodesk Account. That makes licensing part of hiring and departures: assign the seat on day one and reclaim it on the last day, along with email and file access. Autodesk also sells Flex, prepaid tokens for occasional use, which can suit someone who opens a product a few days a month. Keep one list of every subscription (Autodesk, Adobe, Bluebeam, rendering tools, Microsoft 365), its renewal date, and who holds each seat. An onboarding and offboarding checklist keeps this from depending on memory.

How Long Should You Keep Project Archives, and How?

There are two separate jobs here: backing up live work, and preserving closed projects.

Live projects. Follow the 3-2-1 pattern: three copies, on two kinds of storage, one of them off site. For ransomware (malware that encrypts your files and demands payment), the important detail is that at least one copy cannot be changed or deleted from the office network, either because it is offline or because the backup service locks it for a set period. Test a restore of a real project file on a schedule. The business data backup guide walks through the choices.

Closed projects. California’s statute of repose, Code of Civil Procedure section 337.15, bars most actions for latent (hidden) deficiencies in design, specification, planning, or supervision of an improvement to real property more than 10 years after substantial completion. That is one reason to talk with your attorney and your professional liability insurer about a written retention period before deleting anything. This is IT guidance, not legal advice.

For the archive itself:

• Save final deliverables as PDF alongside the native files.
• Record which software version each project was last saved in. Newer Revit versions upgrade older models when they open them, so keep an untouched copy of the original.
• Store the archive read-only, with a second copy in a different place.

The Risks Specific to Design Firms

• Deadline pressure. Losing access to files the week of a submittal is the costly scenario. It is an argument for tested restores, not only for having a backup.
• Central model corruption from unsupported sync setups, described above.
• Email fraud around invoices. Design fees and consultant payments move by email. Turn on multi-factor authentication (a second proof of identity beyond the password) for every mailbox. CISA’s ransomware guide and the post on ransomware protection cover the wider basics.
• One person holding the keys. If a single employee is the only administrator of the Autodesk account or the NAS, document those logins in a business password manager.

Checklist You Can Copy

1. List every workstation with its processor, memory, graphics card, and Windows version.
2. Find your largest Revit models and compare them with Autodesk’s tiers.
3. Confirm no central model lives in a synced Dropbox, OneDrive, or Google Drive folder.
4. Wire every design desk and the plotter. Update plotter firmware and change its admin password.
5. Put guest Wi-Fi on its own network.
6. Turn on multi-factor authentication for email, Autodesk, and Adobe accounts.
7. Confirm backups include the server or NAS, cloud files, and the archive, with one copy that cannot be altered.
8. Restore one project file as a test and note how long it took.
9. Write down a retention period for closed projects after talking to your attorney and insurer.
10. Keep one list of licenses, renewal dates, and seat holders.

Questions to Ask Any IT Provider

• How would you size a workstation for our largest model, and which Autodesk tier are you matching?
• Where will our central models live, and is that arrangement one Autodesk supports?
• Which backup copy is protected from deletion, and how often will a restore be tested?
• How will staff reach files from outside the office?
• Who will hold administrator access to our Autodesk, Microsoft, and storage accounts, and how is that documented for us?
• What happens to licenses and access when someone leaves?

When You Do Not Need All of This

A sole practitioner working in AutoCAD and SketchUp does not need a server. A good workstation, cloud storage for documents, and a backup with one protected copy cover it. A two-person studio whose models stay under 300 MB can run on Autodesk’s entry tier for a while. Spend first on backup and account security, then on hardware as models grow.

Common Questions

How much RAM does Revit need?

Autodesk lists 16 GB as the minimum, usually enough for a single model of about 300 MB. It lists 32 GB for models around 600 MB and 64 GB or more for models around 1 GB. Check your largest file sizes, include linked models, and leave room for the projects you expect over the life of the computer.

Can we keep Revit central models on OneDrive or Dropbox?

Autodesk advises against expecting file-based worksharing to behave on cloud sync services the way it does on a local network, and lists central model corruption and lost work among the risks. Use a local server or NAS for file-based worksharing, or Revit Cloud Worksharing for cloud collaboration. Sync services remain fine for PDFs and other documents.

Does Revit run on a Mac?

Revit is a Windows application. Autodesk’s requirements page describes running it on Apple computers through Parallels Desktop, a virtualization product, with its own recommended configuration. For daily production modeling, a Windows workstation that meets the tier you need is the simpler route.

Is a gaming PC good enough for Revit?

It can be, if it meets the published requirements: a high single-core clock speed, enough memory for your model sizes, a DirectX 11 capable card with enough memory, and Windows 11. The practical differences with business workstations are usually warranty length and on-site repair options, so compare those before you decide.
