Photo documentation on the construction site: from paper to app

A photo shows what was actually in place at a given moment in a way that words rarely can. That matters most for work that is covered up by the next trade: reinforcement before the pour, fixings before cladding, membranes before backfilling. Once it is hidden, the photo is often the only evidence of what lies behind.

It also matters when questions come up later. If the client, a structural engineer or an insurer asks whether something was done correctly, a dated photo of the right detail settles the matter far faster than anyone's memory. Without it, or if the photo can't be placed in time and location, the case usually becomes slower and more expensive to resolve.

Most construction firms already take plenty of photos. The problem is what happens to them afterwards:

• Photos sit on several employees' phones, mixed in with everything else in the camera roll.
• Comments are written in separate notes, in text messages or not at all.
• The report is assembled by hand, often days later, when the details have started to blur.
• Documentation disappears when a phone is replaced or an employee changes jobs.

None of this says anything about the quality of the work. It is about context: a photo without a date, a place and a clear link to what it documents is hard to use six months later.

Whatever tool you use, the same basic rules apply:

• Link to a control point or task: the photo should show one specific thing that was checked.
• Date, time and place: so it can be placed precisely afterwards.
• A responsible person: who carried out the work or the control.
• A short note: what the photo shows and why it matters, written for someone who wasn't there, such as a structural engineer reviewing the case months later.
• Good light and a clear angle: ideally with a fixed reference such as a folding rule or a grid line in frame, so scale and placement are obvious.

You don't need maximum resolution; what matters is that the subject and the control point are easy to recognise. With paper or the phone's ordinary camera, you have to remember to add all this context by hand every time. That is exactly what a dedicated app does for you.

In Lite Report, the project manager sets up the report on the web: report type, participants, drawings and the tasks to be carried out, built from the control plans and control points for the relevant trade. Workers then carry out their assigned tasks on site from their phone: photograph, comment, mark up and submit. The report is assembled from those registrations, so nobody has to gather photos from several sources afterwards.

• Photos are taken with the app's own camera, not picked from the phone's gallery, so each photo is captured on site when the task is registered.
• Every photo carries the date, time, GPS position and place name stamped on the image.
• Photos and PDF drawings can be marked up to show exactly where the detail is.
• Several people can contribute to the same report, each carrying out the tasks assigned to them.
• An activity log records who did what, and when.

Imagine a site where three trade contractors work at the same time. Each team keeps its photos on its own phones, and a combined report is only put together when the client asks for it, perhaps a week or two after the work was done. By then, it is hard to reconstruct exactly when, and by whom, each control point was carried out.

If each team instead registers its tasks in the same report as the work is done, the photo, the comment, the time and the person are recorded together from the start. When the work is finished, so is the documentation. It only needs to be reviewed and generated.

Be aware that the app needs an internet connection today to register tasks and upload photos. Offline mode is on our roadmap, but it isn't available yet. On most sites mobile coverage is not a problem, but if parts of your site have a weak signal (a basement, for example), check the coverage before you rely on registering there.

A Lite Report export can serve as photo documentation in a DS 1140 case, for example as supporting evidence for the B3 control report. It doesn't replace the project's control plan or the formal DS 1140 documentation and approval, which remain separate. Read more in our article on DS1140 control plan templates. If you want an expert to prepare or check the structural documentation, our sister company KS Danmark does exactly that.

Creating an account, setting up projects and documenting on site is free. You pay only when you generate a finished report: 149 DKK excl. VAT (186.25 DKK incl. 25% VAT) per report. There is no subscription, no minimum and no lock-in, and no extra charge for users or photos. See pricing for the details.
