Trimble Business Center vs SitesAI Estimate
Two ways to get earthwork quantities from plans: a civil office suite that also builds models for machines, or a browser-only cut and fill takeoff tool with published per-user prices. Trimble Business Center (TBC) turns field and design data into 3D constructible models, estimates and bids and delivers data to machines in the field; SitesAI Estimate calculates cut and fill from PDF, DWG or DXF plans in the browser, with an optional AI auto-takeoff plan. Not like-for-like. Desk research from vendor pages read Oct 19, 2026; not tested, no winner.
In short: Trimble Business Center (Earthwork takeoff & civil data prep; no public prices (quote / sales)) vs SitesAI Estimate (Earthwork takeoff; vendor publishes prices). Facts last checked Oct 19, 2026. No winner declared; not tested.

| AI role (our label) | AI features added to established product | AI features added to established product |
| What it does | Civil construction office software that turns field data into 3D constructible models, estimates, and bids. It adds CAD/drafting tools and data delivery to machines in the field. Release notes for TBC 2026.10 mention a beta AI Assistant and AI-driven curb ramp and pavement inspections. Re-checked Oct 19, 2026: the civil construction product page still describes CAD/drafting, takeoff designs, construction models and data delivery to machines; no public prices on the page. | Browser-based earthworks takeoff and estimating that calculates cut and fill from PDF, DWG or DXF plans, with an AI auto-takeoff plan. You load a PDF, DWG or DXF, calibrate scale, trace work areas and set existing/design levels; it calculates cut and fill, shows 3D terrain for levels and batters, and exports quantities to Excel or PDF. The AI plan adds AI auto-takeoff (draft for human review) and an MCP connector so Claude, Codex or ChatGPT can drive the same tools. Runs at takeoff.sitesai.net with Google or Microsoft sign-in. Re-checked Oct 19, 2026: the estimate page still lists Free (markup and 3D terrain on one sheet, no cut/fill volumes), Pro and AI plans, and states a 30-day money-back guarantee on paid plans and a 14-day free trial of the AI plan with no card (one per account). |
| Who it's for | Survey and civil construction professionals. | Civil and earthmoving contractors pricing cut and fill from plans. |

Earlier note (Oct 13, 2026): a 21-day free trial is offered. Confirm current pricing with the vendor. | Free: markup and 3D terrain on one sheet (no cut/fill volume figures). Pro: $39/user/month or $390/year (volumes, unlimited sheets, Excel/PDF export, cloud sync). AI: $99/user/month or $990/year (adds AI auto-takeoff and MCP connector; 14-day free trial of AI plan, no card, one per account). USD.

Where the vendor descriptions differ
- Scope: TBC's civil construction product page describes CAD and drafting, takeoff designs, construction models and data delivery to machines in the field, so the office model can also feed the field. SitesAI Estimate is narrower: you load a PDF, DWG or DXF, calibrate scale, trace work areas and set existing and design levels, and it calculates cut and fill, shows 3D terrain for levels and batters, and exports quantities to Excel or PDF.
- Where it runs: SitesAI Estimate runs in the browser at takeoff.sitesai.net with Google or Microsoft sign-in. TBC is Trimble's office software for survey and civil construction professionals, offered as a trial download (a 21-day free trial was listed at our Oct 13, 2026 check).
- AI: TBC 2026.10 release notes mention a beta AI Assistant and AI-driven curb ramp and pavement inspections. SitesAI's AI plan adds AI auto-takeoff, which drafts a takeoff for human review, and an MCP connector so Claude, Codex or ChatGPT can drive the same tools. Both carry our AI features added to established product label.
- Pricing (checked Oct 19, 2026): SitesAI publishes prices: Free (markup and 3D terrain on one sheet, no cut and fill volumes), Pro at $39 per user per month or $390 a year, and AI at $99 per user per month or $990 a year, with a 30-day money-back guarantee on paid plans and a 14-day free trial of the AI plan with no card. TBC has no public prices; its call to action is Get a quote.
- Who each names: TBC names survey and civil construction professionals; SitesAI names civil and earthmoving contractors pricing cut and fill from plans. Neither tool has been tested by Means & Methods Lab.

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.
Questions to ask in your review
- Whether both give the same cut and fill on one plan set, checked against a surface-to-surface answer you already trust
- How SitesAI handles plans with sparse spot elevations or contours, compared with a TBC surface built from survey data
- What a TBC licence costs for one estimator seat; Trimble does not publish prices
- What did you use it for, on what kind of work and project size?
- How long did setup and training take, and who on your team did it?
- What does it cost you in practice, compared with what the sales call said?
