Case · Construction · Construction company running six sites at once
The delay showed up in the monthly progress certificate, a month later. Now it shows up on Friday. And the site's client gets it too.
The site manager sends the daily report by WhatsApp. The system checks it against the schedule and every Friday builds an alert when a trade drifts and a one-page report for the site's client.
Sample data This case is built with sample data until the client's written permission exists. Real numbers get published with name, period and method.

weeks of lead time before a deviation shows up
How it was measured Difference between the date the report shows a deviation and the date of the monthly progress certificate, sites from May–August 2026.
The context
Buenos Aires · 70 people · 6 sites at once · schedule in MS Project, daily reports by WhatsApp, Google Drive.
Integrated with WhatsApp · construction schedule (MS Project) · Google Drive.
The capability Construction site tracking
- 01
What nobody knew
How far each site had drifted from the schedule, week by week. It was known at the certificate, when there was no room left to fix it.
What was looked at, and what wasn't
The site manager knew how his site was going, from memory. Management found out at the monthly meeting, with the certificate.
- 02
What showed up when we looked
In the first week, two of the six sites had a deviation of more than 10% in one trade: concrete in one, installations in the other. The installations one was a supplier that wasn't delivering, and nobody outside the site knew.
- 03
What decision changed
The supplier was changed three weeks before the site would have stalled. And something that wasn't in the plan: the weekly report with photo and deviation started going out to each site's client. Two months later, the construction company put it in the sales pitch, and two private tenders named it as a differentiator. Clients who get the report: 6 of 6. New sites where the report was part of the pitch: 2.
- 04
What we built
The site manager sends the daily report by WhatsApp, with photos. The system checks it against the schedule (progress by trade, against date) and every Friday builds two things: an alert to the site manager and management when a trade drifts more than 5%, with the cause the report states; and a report for the site's client, with progress, photo and deviation, on one page. What to do about the deviation is decided by the site manager with management.
How it works

How it's measured from here on
Deviation by site and by trade every week, alerts with action taken, reports sent. Management looks at it Friday afternoon.
