Sitemark started with a simple problem: field crews running precision equipment were still managing critical documentation on paper. We built the tool we needed. Then we realized everyone else needed it too.
Sitemark is not a project management tool with a grade field tacked on. It is not a generic construction app that vaguely supports “field documentation.” It is a platform built from scratch for one specific type of contractor: crews running precision equipment — Topcon, Trimble, Leica, and Spectra — on grade-critical work.
That means grading contractors building roads and site pads. Sewer crews running pipe lasers and generating CIPP pre-lining surveys. Survey companies documenting as-builts on underground utilities. Civil firms managing calibration fleets across multiple job sites simultaneously.
Every feature in Sitemark was built with those specific workflows in mind — not adapted from a generic task tracker, not ported from a desktop tool that assumed you’d be at a desk. The grade verification workflow assumes you have a laser level and a rod. The calibration tracker assumes you have a fleet of Topcon and Trimble instruments with manufacturer-specified intervals. The AI assistant knows the difference between an RL-H5A error code and a DG813 grade error.
That specificity is the whole product. If you run a Topcon or Trimble crew, Sitemark was built for you.
Sitemark is built alongside Express Tools — an authorized dealer for Topcon, Trimble, Leica, and Spectra Precision equipment. That direct relationship with the equipment ecosystem means Sitemark is tested against real instrument data and updated as equipment lines evolve. You’re not using software built by people who’ve only read the spec sheet.
The construction industry has adopted remarkable precision equipment — Topcon laser levels that hold grade to ±1.5mm, GPS/GNSS rovers accurate to ±10mm, total stations with 1-second angle resolution. The equipment is extraordinary.
The documentation process surrounding that equipment is often still paper. A spiral-bound field book riding around in a dirty truck. A clipboard with a calibration log that hasn’t been updated since the last service run. An Excel spreadsheet that someone built in 2014 that the whole company still uses for as-built reports — if they remember to update it.
We watched a sewer crew lose three days of pipe laser readings when their field book got soaked in a rain event. We watched a grading contractor fail an inspection because their laser level hadn’t been calibrated in 18 months — they just didn’t have a system to track it. We watched a survey company spend four hours generating an as-built report from paper notes that should have taken twenty minutes.
None of these problems are technically hard. They’re systems problems.
A digital shot log that can’t get rained on. Calibration tracking that sends you an alert before the inspection, not after. As-built PDF generation that takes one click instead of one Sunday night. An AI assistant that knows the difference between a Topcon TP-L6 error code and a Spectra LL300N error code. That’s what Sitemark is.
Half of our team has logged shots, run pipe lasers, and generated as-builts on actual construction projects. We know what it feels like to be out of tolerance at 4pm with an inspector showing up at 7am.
That field experience shapes every design decision — from the size of touch targets on mobile to the exact format municipal inspectors expect on as-built PDFs.
Our development process starts with contractors: we observe workflows, shadow crews on job sites, and work backward to build tools that fit how field work actually happens — not how it looks in a requirements document.
When we add Topcon equipment knowledge to the AI assistant, we verify it against Topcon’s actual service documentation. The work shows in the details.
We build for workflows where accuracy isn't optional. Grade verification has tolerances measured in hundredths of a foot. Our tools are built to that standard.
A tool that fails on a job site is worse than no tool at all. We ship features when they're ready, not when they're scheduled. Field crews can't afford bugs.
Every feature is designed to work at 6am in a muddy field with work gloves and a phone screen that's hard to see. Desktop-first design has no place in field operations software.
Our pricing is public. Our feature roadmap is shared with customers. We don't hide limitations or upsell you features you don't need.
