Computer Evaluations for an Architecture Firm

A practical buying guide for a modern architecture practice — CAD/BIM workstations, a cheaper drafting tier, shared file server & backup, network, large-format plotter support, and the 10-million-color Mimaki 3D printer — organized by firm size so you buy for the office you have (and the one you're growing into).

Prepared by Yu & Associates for a multi-site architecture practice. Hardware figures where shown are drawn from four vendor quotes already gathered for the firm (2× Autodesk / Dell) — see How your quotes map to the tiers below.

How to read this. Pick the tier that matches your seat count. Each tier lists a full BIM/render seat, a cheaper drafting seat, the server/NAS + backup for multi-site sync, network, and what it takes to drive a plotter and the Mimaki 3DUJ-553 color 3D printer.

Rule of thumb: Revit and AutoCAD reward high CPU clock speed first, then RAM; rendering, point clouds, and color 3D-print prep reward a big-VRAM GPU. Don't overspend on cores for drafting; don't underspend on GPU/RAM for production BIM.

Tier 1

🪑 Solo & Small Studio — 1 to 5 seats

A principal plus a few staff. One shared drawing set, light coordination, mostly one or two people in the heavy 3D model at a time. Keep infrastructure minimal; put the money in one or two strong seats.

Full BIM / render seat

CPU: 8–14 core, high clock (Core Ultra 7/9, Ryzen 7/9)
RAM: 64 GB
GPU: RTX 4000 Ada 20 GB / RTX 2000 Ada 16 GB
Storage: 2 TB NVMe SSD

Drafting / CAD seat cheaper tier

CPU: 6–8 core (Core i5/i7)
RAM: 32 GB
GPU: RTX A1000 8 GB / T400 (AutoCAD-certified)
Storage: 1 TB NVMe SSD

Server / NAS	No server needed. One desktop or 2-bay NAS (e.g. Buffalo TeraStation 16 TB or Synology) as the shared project drive.
Backup	3-2-1: local NAS copy + cloud offsite (Autodesk Docs or Dropbox/Backblaze). No offsite copy = one theft/fire from losing the firm.
Multi-site	Not applicable yet. If a second person works remotely, use Autodesk Docs for the model rather than syncing files by hand.
Network	Gigabit switch, one good business router/firewall, business Wi-Fi (UniFi). UPS on the main seat + NAS.
Plotter	Drive a 24–36" plotter directly from a workstation over USB/network. No print server required.
Mimaki 3DUJ-553	Usually outsource color 3D prints at this size, or let one full seat double as the prep/RIP station (see the Mimaki section).

Tier 2

🏢 Growing Practice — 6 to 20 seats

Multiple project teams, live model coordination, in-house rendering and plotting daily. Now worth standardizing hardware and putting shared storage and backup on real infrastructure.

Full BIM / render seat

CPU: 16-core high-clock (Ryzen 9 / Core Ultra 9 / Xeon w)
RAM: 128 GB
GPU: RTX 6000 Ada 48 GB (or RTX 4500 Ada 24 GB)
Storage: 4 TB NVMe SSD

Standard BIM seat

CPU: 8–14 core high-clock
RAM: 64 GB
GPU: RTX 4000 Ada 20 GB
Storage: 2 TB NVMe SSD

Drafting / CAD seat cheaper tier

CPU: 6–8 core (Core i5/i7)
RAM: 32 GB
GPU: RTX 2000 Ada 16 GB / A1000 8 GB
Storage: 1 TB NVMe SSD

Mobile seat (principals / site)

CPU: Mobile 16-core (Core Ultra 9 HX)
RAM: 128 GB
GPU: RTX PRO 5000 24 GB
Storage: 4 TB NVMe SSD

Server / NAS	Dedicated 8-bay NAS (Synology/QNAP), ~40–80 TB usable in RAID 6, 10 GbE uplink. Add a small server if you want a local Autodesk license/print host.
Backup	NAS snapshots + a separate backup target + cloud/immutable offsite. Test a restore quarterly.
Multi-site	Use Autodesk Docs / BIM Collaborate for live model sync between offices — don't try to mirror a NAS over the WAN for active Revit files.
Network	2.5/10 GbE to the NAS and heavy seats, managed switch, VLANs (staff / guest / devices), UniFi or Firewalla firewall. UPS on server + NAS + core switch.
Plotter	Networked 36–44" plotter; host the print queue on the NAS or a small print server so every seat prints without a driver babysitter.
Mimaki 3DUJ-553	One dedicated prep/RIP workstation at the full BIM/render spec (48 GB GPU, 128 GB RAM, 4 TB) drives the printer for the whole office.

Tier 3

🏛️ Multi-Site Firm — 20 to 50+ seats

Several offices, shared federated models, heavy rendering/reality-capture, and centralized IT. Now infrastructure — servers, WAN, backup, license and print management — matters as much as the seats.

Full BIM / render seat

CPU: 16–24 core high-clock (Threadripper / Xeon w)
RAM: 128–256 GB
GPU: RTX 6000 Ada 48 GB
Storage: 4 TB+ NVMe SSD

Standard BIM seat

CPU: 8–14 core high-clock
RAM: 64 GB
GPU: RTX 4000 Ada 20 GB
Storage: 2 TB NVMe SSD

Drafting / CAD seat cheaper tier

CPU: 6–8 core (Core i5/i7)
RAM: 32 GB
GPU: RTX 2000 Ada 16 GB
Storage: 1 TB NVMe SSD

Mobile seat (principals / site)

CPU: Mobile 16-core (Core Ultra 9 HX)
RAM: 128 GB
GPU: RTX PRO 5000 24 GB
Storage: 4 TB NVMe SSD

Server / NAS	Rack server at HQ (e.g. Dell PowerEdge R570, 24C/48T Xeon, 128 GB) for file/license/render/print services, plus a NAS at each site. Size storage well past the 2×3.84 TB base — BIM + laser scans grow fast.
Backup	3-2-1-1-0: local + NAS + cloud + one immutable/offline copy, monitored restores. Per-site NAS backs up to HQ nightly.
Multi-site	Autodesk Docs / BIM Collaborate Pro for live models across offices; site-to-site VPN or SD-WAN for shared services and admin; central Autodesk account/SSO for seat control.
Network	10 GbE backbone at HQ, per-site managed switching + UniFi/Meraki, redundant WAN at HQ, QoS for cloud model sync. UPS + generator-ready rack.
Plotter	A plotter at each site; central driver/preset & print-queue management from the server so sheet output is identical firm-wide.
Mimaki 3DUJ-553	Dedicated color-3D prep seat + fast storage for the color-model library; printer lives at HQ and serves all sites. Confirm RIP/color workflow & service plan with the Mimaki reseller.

🖨️ Large-format plotter support

A plotter is undemanding on the host — it needs a reliable spooler and enough disk for big plot files, not a fast GPU. What machine drives it depends on how many people print:

Solo / small: Drive a 24–36" plotter directly from a workstation over USB or network. Install the plotter's HP-GL/2 or PostScript driver on that seat.
Growing / multi-site: Put the plotter on the network and host the print queue on the file server or a small print-server VM. Every seat prints to a shared queue with standardized page setups — no per-machine driver drift. Add a RIP only if you plot color renders/presentation boards, not just line-work sheets.
Hardware (not in the current quotes): HP DesignJet T-series (T950 / T1700) or Canon imagePROGRAF TX — 24" to 44" roll-fed. Budget a service/consumables plan separately.

🎨 Mimaki 3DUJ-553 — 10-million-color 3D printer

This is the demanding peripheral. The 3DUJ-553 is a full-color UV-inkjet printer that produces physical models in up to 10 million colors from textured CAD — the standout "wow" deliverable for client presentations. The printer itself is separate; what your computers need to do is prepare and RIP the color models, which is CPU-, RAM-, and storage-heavy.

What the host machine needs

Class	Match a full BIM / render seat — this is the most demanding prep task in the office.
GPU	Big-VRAM pro GPU (RTX 6000 Ada 48 GB) for previewing large textured/color models.
RAM	128 GB — color voxel models balloon in memory during slicing.
Storage	4 TB+ fast NVMe; keep a separate library volume — finished color models are large.
OS	Windows host, per Mimaki's driver/RIP requirements.
Software	Mimaki 3D LINK + the 3DUJ RIP: import OBJ / PLY / VRML / 3MF with vertex colors & textures exported from Revit, Rhino, 3ds Max, or SketchUp, then color-manage and slice.

⚠️ Confirm before you commit

The plotter and the Mimaki-class color 3D printer are not covered by the current Dell/Autodesk quotes. The quoted workstations can absolutely drive them, but you still need the vendors to confirm:

Exact Mimaki 3D LINK / RIP software version and the ICC/color-managed workflow.
The plotter's driver + optional RIP and where the print queue lives.
Service & consumables plans for both devices — these are ongoing costs the hardware quotes don't include.

🧾 How your four quotes map to the tiers

You already gathered four vendor quotes. Here's where each one fits — all four are Tier 2 / Tier 3 grade, which is the right ambition for a multi-site firm:

Quote	Spec	Best used as
Autodesk AEC Collection + Forma $27,610 / 3 yr	2 seats · Revit, AutoCAD, Civil 3D, 3ds Max, Docs + Forma	The software foundation for every tier. Start at 2 seats; add seats as headcount grows. Forma covers early design + collaboration.
Dell Pro Max Tower T2 $22,038 / 2	RTX 6000 Ada 48 GB · 128 GB · 4 TB SSD	Your full BIM/render seats — and the ideal Mimaki 3D prep/RIP station. The strongest hardware buy here.
Dell Pro Max 18 Plus $23,518 / 2	RTX PRO 5000 24 GB · 128 GB · 4 TB SSD	Mobile seats for principals & site work. Great for field review — don't let them replace fixed seats for daily heavy rendering/printing.
Dell PowerEdge R570 $29,288.70	24C/48T Xeon · 128 GB · 2×3.84 TB NVMe	HQ file / license / render / print host for Tier 3. Buy if you want local infrastructure; expand storage — the base is modest for BIM + scans.

The Dell bundle also included 4× Dell U2724D monitors, 2 dual-monitor arms, a Xerox C325/DNI color laser all-in-one (check-prints), and a Buffalo TeraStation 16 TB NAS — a sensible Tier 1/2 shared drive.

Bottom line. Standardize on Autodesk AEC + Forma for software and Dell Pro Max Tower T2–class machines for production seats and Mimaki prep. Fill out the rest of the office with standard BIM seats and cheaper drafting seats, size shared storage and backup to the tier, and treat the plotter and 10-million-color 3D printer as a confirm-with-vendor line item on top of the compute.
