The documents say one thing. The field says another. We surface every gap.
We read every document on the job and compare it against the field. Substitutions, undocumented changes, and completion gaps surface as flags with the evidence next to the document, while there is still time to fix them.
Your documents and your field stop agreeing the moment construction starts.
Two records, one asset
Every large project starts with two records of the same asset. The physical one in the field, and the document one that defines what should exist: models, specs, approved submittals, certs, test records, change orders.
Construction breaks the match
When construction starts, lead times force substitutions that never make it into the submittal log, drawings get revised but crews work off the old set, and completion sign-offs drift from what is actually installed. Within weeks, the documents and the physical project are telling two different stories about the same job.
The cost of finding it late
Closing that gap has always fallen to senior people walking the site by hand on a fraction of the work. The errors that slip through get found at hydrotest, at commissioning, or at startup, when the same fix costs ten to a hundred times more than it would have at install.
We compare what the documents say to what is actually there.
Landex starts with your project documentation: the model, the submittal log, the equipment list, the line specs, the completion records, the change orders. That is the description of what should exist. We then look at the physical project through whatever your team is already capturing, including laser scans, 360 walkthroughs, and drone footage. That is the description of what does exist.
Where the two records disagree, we generate a flag with the photo evidence next to the governing document, so your team can resolve it before the cost of fixing it multiplies.
By handover, every element on your project carries a verified record of what it is and what governs it. The as-built is true for the first time.
A sample of what shows up in the report.
Fisher approved. Crane installed. No record of the change.
The submittal log lists Fisher for FCV-2034. The field shows a Crane valve installed at that location. No change record exists in the RFI log, the submittal revisions, or the change order register. Two additional substitution flags this week, both involving motor model differences on equipment in the P-100 series. Each flag includes the source submittal page, the field photo, and the absence of any documented approval.
Signed off Thursday. Still open Monday.
The completions database shows System 7B as fully signed off as of last Thursday. The capture from Monday shows two block valves in the open position, one flange unbolted, and the temporary blind still in place on the south header. The opposite case also shows up: System 9A is physically complete in the field, but no ITR has been signed.
A line moved. No MOC, no RFI, no inspection record.
A diff between the capture from two weeks ago and the capture from this week shows a 4-inch line on the east rack has been rerouted. The displaced pipe support has been removed and two new welds added. No MOC, no RFI, and no change order on file. The new welds carry no inspection record because none was scheduled.
600# specified. 300# installed. Full pressure at startup.
Line 12-P-114 is specified as 600# in the piping class. The flanges on the run between FCV-2034 and the pump skid show an 8-bolt pattern, which corresponds to 300#. The wrong pressure class is installed on a line that will see full operating pressure at startup.
847 of 894 verified. Here is what we still need.
847 of 894 elements on this week's report were verified against the documents. 47 remain unverified, mostly insulated components and six with no readable identity from current capture angles. The report includes the list of unverified elements and the targeted shots needed to close coverage in next week's walk.
Documents in. Field in. Disagreements out.
Your documentation comes in.
Drawings, models, submittals, schedules, change orders, line lists, completion records. Whatever your team is already maintaining as the project's source of truth.
Your capture comes in.
Phone video, 360 cameras, drone footage, laser scans. Whatever your team is already capturing in the field. No new hardware, no new field behavior.
We compare the two.
For every element the documents describe, we check the field. For every element the field shows, we check the documents. Substitutions, undocumented changes, wrong specs, completion gaps, and missing change orders all surface as flags with the source documents cited.

Built for anyone responsible for getting a project built right.
If your project gets built, gets inspected, and gets handed over, Landex fits.
Industrial and process facilities
Plants, refineries, petrochemical, LNG, chemical manufacturing. Element-rich projects where document linkage to physical work is the difference between a clean commissioning and a six-month closeout. This is where substitution catches alone pay for the system.
Energy and utilities buildouts
Substations, generation, pipeline construction, distribution upgrades. Projects where regulatory inspection trails matter as much as the physical work.
Civil and heavy infrastructure
Roads, bridges, transit corridors, water and wastewater. Long-duration projects where the record has to stay honest across phases and through crew turnover.
Commercial and institutional construction
Office, healthcare, life sciences, data centers, education, mixed-use. MEP-heavy work where the gap between design and as-built is most expensive.
Tell us about your project.
Let's do a 20-minute call. We will walk you through what Landex would do on a project like yours, and what a pilot looks like.
We can start on a small section of one project, whether it is one room, one module, or one system. You see what we find, and you decide whether it is worth expanding to a whole site.
