The Tuesday Brief, by Rosa Calder (a house pen name). The week’s SketchUp news and what it means for you.
SketchUp has a new subscription tier aimed at the field rather than the studio: SketchUp Pro Civil Contractor, listed in early October 2026. It is SketchUp Pro plus two Trimble extensions, Trimble Site Contractor and Trimble Field Points, which turn a SketchUp model into site-layout and machine-control data. If you do architecture, interiors or woodworking, you can ignore it. If you design foundations, excavations or site grading, read on, because the real cost is not on the SketchUp price tag.
What changed
According to the SketchUp Help Center, Civil Contractor includes everything in SketchUp Pro (Desktop, LayOut, full SketchUp for Web and SketchUp for iPad), Trimble Connect cloud storage, Extension Warehouse access, 150 SketchUp AI credits per month, and the two extensions.
- Trimble Site Contractor exports SketchUp geometry as design files for the Trimble Siteworks ecosystem, for layout and for machine-ready use.
- Trimble Field Points brings geolocated points into SketchUp as design references, so you can model against what the crew actually measured.
The help pages describe the workflow at a high level: model an excavation from a foundation plan, convert it to Siteworks design files, take it to the field for layout or to a machine for excavation and grading, then pull measured points back in to revise. A third-party changelog summarizing the launch lists export of linework and terrain models, import of Siteworks field data, and support for control points and georeferencing. Check the official Site Contractor pages for the exact file types and menu locations before you build a process around them; the overview page itself does not name them.
Site Contractor is not strictly new. The Help Center says it is also available through the SketchUp Pro Advanced Workflows and Studio subscriptions. Civil Contractor is a cheaper, narrower way to get it.
What it costs
The store page lists the annual plan at $499 per year (about $41.58 per user per month billed annually), excluding tax. Enterprise and education pricing goes through sales. Prices vary by region and change, so confirm at checkout.
Here is the catch. The Help Center is explicit that Trimble Siteworks is required to use the subscription, and Trimble Earthworks Grade Control is needed for machine guidance. Neither is included. You buy them separately from a reseller or supplier, and I could not find a public Siteworks price. Budget for the whole chain, not just the $499.
Worth it?
- Time saved: removes the manual re-drawing or re-exporting between a SketchUp site design and field data, if you already work in Siteworks.
- Cost: $499/year for the SketchUp side, plus Siteworks (and Earthworks for machine control), priced separately.
- Who should skip it: anyone not running Trimble field equipment or Siteworks, and anyone who only needs SketchUp Pro. Site Contractor needs SketchUp for Desktop; the supported versions are listed on the Getting Started page, so verify yours first.
Who it matters to
- Site and civil contractors who model excavations or pads in SketchUp and hand them to crews. This is the target audience.
- Landscape designers doing grading who already deliver to a Trimble-equipped contractor. Build the terrain properly first; our SketchUp Sandbox terrain guide covers contours and pad stamping.
- Everyone else: nothing changes in your plan. Your Pro subscription is untouched.
Before you buy
- Confirm your field crew or firm actually uses Trimble Siteworks, and which version.
- Check your SketchUp version against the Site Contractor requirements. If you are on an older release, see our note on SketchUp end of support before choosing an upgrade path.
- Get a Siteworks quote first. It decides whether the bundle makes sense.
- Keep the model clean. Tidy, correctly oriented geometry exports better; our slow model checklist helps with bloated files.
- Pilot on one small pad or footing before committing a live project.
What this means for you
- New Civil Contractor tier: act now only if you already own or plan to buy Siteworks and design site work in SketchUp. Otherwise ignore it.
- Siteworks and Earthworks not included: get quotes before you compare prices with Pro.
- Site Contractor also in Advanced Workflows and Studio: if you already hold one of those, you likely have it already.
FAQ
What is SketchUp Pro Civil Contractor?
A SketchUp subscription that adds the Trimble Site Contractor and Trimble Field Points extensions to everything in SketchUp Pro.
Does it include Trimble Siteworks?
No. Siteworks and Earthworks Grade Control are bought separately from a third-party reseller or supplier, per the SketchUp Help Center.
How much does it cost?
The store page listed $499 per year for the annual plan at the time of writing, excluding tax. Siteworks costs are extra, and pricing may vary by region.
