Built by utility coordinators, for coordinators
Underground utility coordination for data center campuses, and for any site that starts with a trench.We check every utility model against every other and against the ground, and track every conflict until it is closed.Or your team does it with Undersite.
Any 3D model format, we convert Report in three working days Fewer than 10 conflicts found, no invoice
A missed conflict under a campus is found by an excavator.Found on screen, it costs an email.
fewer hours per campus review: 10 to 14 instead of the 40 to 60 it takes by hand.
from your files to a report with every conflict pinned in 3D.
return on coordination in a published design-build project: $200k of coordination, $2.2M of rework avoided.
DBIA case studyData center campus, four buildings
800conflicts worth fixing, found in the final phase alone.
Data center campus, eight buildings
2,700+conflicts found in the final phase, filtered down to the ones that matter.
Four steps, three working days to the report, nothing for you to install or export.
Every review comes with the campus in 3D, in the browser.Your team and your designers open it, find any pipe and follow each conflict to where it is.
A clash test knows two solids touch.A coordinator knows the rules between them.
Clearance by utility pair and by which one is on top.
Horizontal separation, like 10 ft between water and sewer.
The least cover on every run, measured to your ground surface.
Solids that overlap, with the depth of the overlap.
Survey and contractor models against the issued design.
Manholes, handholes and chambers against the runs around them.
Data center campuses are where we work most. The same checks run on any site with buried utilities.
General clash tools were made for buildings.Under a campus the rules are different, and so is the work.
Rules the way civil coordinators write them, not hard clashes between solids.
Every conflict keeps its history from 30% design to as-built.
In the browser, no install, no license server. A link in the report opens the conflict.
Kept on your computers by default. Shared links are encrypted in the browser.
Send the 3D models the designers send you. Converting them is our job.
We coordinate data center campuses for a living. Undersite is the tool we needed, and you get us with it: rules set up, reviews run, your team trained.
| What matters | Undersite | General clash tools | By hand or outsourced |
|---|---|---|---|
| Made and supported by working utility coordinators | Built in: we set it up with you | Software only | Depends who you hire |
| Clearance by utility pair and by which one is on top | Built in | One test per pair, set up by hand | Checklists |
| Cover and depth to the real ground | Built in | Not built for it | Sections drawn by hand |
| Manholes and chambers against the runs around them | Built in | Hard clashes only | By eye |
| Conflicts carried from one revision to the next | Automatic: not found, reopened | Re-run and reconcile | Spreadsheets |
| Coordination report | PDF and online, each conflict linked to the model | Exported, then edited | By hand |
| Files you can send | Any 3D model format, we convert | Format by format | Depends who does it |
| Where models are kept | Your browser, by default | Desktop files or a vendor cloud | Their servers |
| How you pay | Per campus, any number of users | Per seat | Per hour |
Put in your own numbers.The defaults are a typical campus with a model drop every month.
Assumes 75% fewer hours per drop and half of the field conflicts caught on screen. Your results depend on your models and your team.
We do the coordination, or your team does it with Undersite.Clear prices, no seat counting for teams.
If a campus review finds fewer than 10 conflicts worth fixing, you do not pay for it.
Fixed prices, US projects, any 3D model format.

Prices in US dollars, for US projects. Another currency, another kind of site or project, or another way of working together: write to us and we quote it separately.
Campus models are sensitive.Undersite is built so they do not have to leave the computer they are opened on.
Models stay on your coordinators' computers. Conflicts, reports and the revision record are shared with the team.
The campus with its conflicts, locked in your browser with a passcode we never see.
Data center campuses are most of our work, so the rules, samples and defaults start there. The checks themselves work on any site with buried utilities: hospitals, chip and battery plants, airports, logistics hubs, university and corporate campuses, substations and industrial sites.
3D models of the utilities and the ground surface, from any design, survey or modeling tool, in any version. We convert them ourselves. Drawings alone are not enough: the checks need depths and shapes in 3D. If you only have 2D drawings, ask us: modeling them is quoted separately.
Those are general coordination platforms: they find solids that touch and manage conflicts for every trade. They do not know that water needs 10 ft from a sewer side by side but 18 in where it crosses above it, how deep a duct bank sits under the real ground, or what clear space a manhole needs. Undersite is built only for buried utilities, by coordinators who do this work, and it comes with us: we set up your rules, run the reviews or train your team. Many clients keep their platform for the buildings and use Undersite underground; conflicts export to a spreadsheet for any tracker.
Three working days from the day we have the files. You get the report as PDF and online, with every conflict pinned in 3D and linked to the same place in the model, and a one-hour coordination meeting where we go through every conflict with your team.
Yes. Every campus review ends with a one-hour meeting where we go through each conflict with your team and, if you want, the designers and contractors. In coordination plans we run the meeting from the report, every two weeks or every week, and the next report says what was agreed and what changed.
A summary of the open conflicts and who resolves them, what changed since the last report, a page for every conflict with its picture, measurements, the rule it breaks and the action, and the full register. Every conflict links to the same place in the 3D model online. Each new report says what was closed, reopened and changed since the one before.
If a campus review finds fewer than 10 conflicts worth fixing, you do not pay for it. It applies to campuses with at least five utility models between 30% and 90% design.
You send them through your file share or CDE, or a private upload link from us. We work on them only on our encrypted machines. You get the report and a read-only link locked with your own passcode. We delete your files and our working copies within 7 days of the report, the read-only link after 90 days or sooner if you ask, and confirm it in writing. For ongoing coordination we keep them for the length of the contract and delete them within 30 days after it ends.
Not yet. The app keeps models in the browser by default, shared links are encrypted in the browser with AES-256 and a passcode we never see, and we host in the US on providers audited under SOC 2 Type II and ISO 27001. We answer security questionnaires and sign NDAs and data processing agreements. If your procurement needs our own report, tell us early.
Yes. Onboarding sets up your clearance tables and rules, loads a first campus from your models, and trains your team live for two hours, recorded. It is included in yearly Team plans.
No. We check the designed and modelled utilities against each other and against the ground. Before anyone digs, the site still needs its 811 call, locates and, where the project calls for it, a subsurface utility engineering survey.
We reply within one working day with a fixed quote and a start date.
