A Heavy Civil Contractor Lands Job-Site Photos on Its Own Servers Through a Files.com Pass-Through

A US heavy civil contractor builds highways, airports, tollways, stadiums, mining operations, and large-scale data centers.

Almost none of that work happens in an office. The contractor's crews operate on dispersed job sites, carrying tablets and phones rather than workstations, and the company builds its own field applications in-house to run the work. The photos, survey data, and documents those crews capture are the office's record of what was found and done on site. All of it has to travel from the job site back to the contractor's servers.

Field Data Needed a Secured Way In

For years, crews relayed photos and documents back through an on-premises file server. Because crews are wherever the work is, the way in has to be reachable from any job site, on a phone or a tablet.

When the contractor scoped a replacement, IT set the bar for that entry point: SSH-secured transfer and two-factor authentication on every account, for a field workforce that connects from job sites rather than from desks on the corporate network.

Cloud Storage Could Not Be the System of Record

The obvious fix was to point field uploads at a hosted file service and shut the old path down. The contractor's IT directive ruled that out before it started. Cloud storage at the company is reserved for non-critical data. Anything critical has to be recoverable on the company's own on-premises servers in a disaster. A project's field record is critical, so a cloud service could never be its only home.

That left a bind. A cloud entry point was the right front door for the field, and the directive said the cloud could never be the record. The fix had to do three things at once: give field crews and field applications an easy, secured entry point in the cloud, hold that entry to IT's bar of SSH and two-factor authentication, and land everything on the contractor's own servers automatically, so the cloud copy was never the copy that mattered.

The contractor selected Files.com to be that layer: a cloud entry point for the field, with the landing on-prem.

A Pass-Through, Not a Destination

Files.com became a new route between the field and the contractor's data center, rather than a place where data lives.

On the intake side, the contractor's in-house Microsoft PowerApps applications write field data directly into Files.com, and crews upload job-site photos through the Files.com mobile app. System transfers run over SFTP, and two-factor authentication applies to accounts, which is the security bar the project was scoped against.

On the landing side, the Files.com Agent runs inside the contractor's network and syncs everything that arrives in the cloud down to the company's on-premises servers. The Agent makes only outbound connections to Files.com, so the contractor's destination servers do not have to accept any inbound connection for the sync to work. The public-facing surface belongs to Files.com, while the contractor's servers remain the system of record.

A Day's Photos in One Action, and Everything Lands On-Prem

With the pass-through in production, the contractor's Files.com field-capture path runs from the phone to the data center. Photos and application data captured in the field land on the contractor's on-premises servers with no one moving files by hand. The crew uploads, and the Files.com Agent brings everything home on its own.

Each field application the in-house team builds can write into the same Files.com pass-through, inheriting the same secured entry and on-premises landing without new infrastructure to stand up.

Bulk mobile upload is what made the path practical at field pace.

Field Data Comes Home on IT's Terms

A crew member can select the day's photos on a phone and upload once. Files.com then delivers those files to the contractor's own servers through a path that never asks the company's network to accept an inbound connection.

The contractor did not have to choose between a cloud front door for the field and its on-prem system of record. Files.com is the pass-through, not the destination, and that is exactly what made a cloud layer acceptable to an IT organization whose first rule is that critical data comes home.
