Paris Aéroport (Paris Airports) is the airport authority that owns and manages the fourteen civil airports and airfields in the Île-de-France (Paris) area. Groupe ADP is a world leader in airport design, construction and operation.


Painful certified mail processes, delayed notifications, deferred actions and lots of wasted time. These are the main issues that Groupe Aéroports de Paris faced when trying to communicate and collaborate with other stakeholders to manage the Jonction project in the Paris-Orly airport.


By using one comprehensive mobile construction app solution to run all aspects of project management of the airport extension project, ADP was able to increase productivity, eliminate unnecessary “certified mail” processes, and provide the group and shareholders full visibility and transparency into their project portfolio.

Currently, Groupe ADP uses (70) ŷAV licenses for their team of 120 engineers to manage the progress and the Operations-Prior-to-Acceptance (OPA) of their construction sites on the Orly and Roissy CDG Platform.

Certified Mail Communication

For Charles, Project Executive at Groupe ADP, the success of a project hinges on communication and organisation. Working with different shareholders and various subcontractors on “certified” communication contractual agreements made sharing information between shareholders time-consuming and unnecessarily delayed their workflows.

Contractual agreements with subcontractors involved communicating with “certified mails” between parties. Sometimes, it took three weeks to officially notify other parties about defects encountered in a site visit. Charles often found himself spending more time waiting around for replies than managing actual work in the project. The process usually starts off with ADP sending a certified mail to a subcontractor to inform of a defect or problem wherein the recipient contractor would reply by certified mail that they have received notification within two days. The said contractor would then propose and send a solution by certified mail again within the next five days, in which ADP would have two days to accept or reject. That’s a total of 9 days for one defect to be addressed.

To create a more efficient workflow, Charles needed to replace this time-consuming process with one solution that could successfully enable transparent project collaboration from start to finish. They needed software that could offer project shareholders visibility into the activities and tasks that concern them, provide a high-level overview to project owners and managers, and give subcontractors the right tools to communicate without having to manually certify by mail and pull out the pen and paper before sending solution proposals by email.

Keeping Everyone in the Loop

“A tool is only as useful as it is usable,” Denise, ADP’s CIO quips. To accurately complete a quality project, Denise considers clear communication of daily activity logs and punch lists as highly necessary. The “certified mail” process took forever to create, review and share information. With ŷAV, ADP’s shareholders and different teams are now able to complete daily logs, punch lists, and quality inspection reports at the time of the walkthrough.

A Time-Saving and Transparent Solution

Prior to using ŷAV, ADP relied on manual tracing of activities through certified mails. ADP wasted lots of time waiting for subcontractors’ replies to complete one task. Charles, Denise, and the whole ADP team are now confident that information pulled into and exchanged within ŷAV is accurate because it’s synced directly within the app in real-time. There is no need to waste effort on unnecessary administrative task as there is no need to edit or alter information along the way. Every activity is now traceable and all accounted for.
