Technology streamlines construction of tunnel project in Italian Alps

The construction of the Perca Bypass, a critical infrastructure project underway in the Italian Alps, highlights the increasing role of advanced technology in managing complex builds. Located near the village and commune of Perca — a destination known for its tourism trade — the new 632 m tunnel and supporting road network are designed to improve regional connectivity and enhance commuter safety.

The project, which began in 2023 and is expected to take three years to complete, is being delivered through a joint venture between European construction group Strabag and regional specialist Alpenbau. Once finished, the bypass is expected to relieve the flow of up to 26,000 vehicles that pass through Perca daily during peak periods, easing congestion and opening new routes for both tourism and local commerce.

Given the large number of machines, teams, and partners involved, coordinating the work requires effective management and communication tools. Alpenbau, drawing on a long-standing collaboration with Topcon Positioning Systems, the team is now using Topcon’s Aptix Integration Platform, which enables site managers to monitor and oversee progress remotely, offering real-time insights into workflow and project status without leaving their offices.

Acting with Aptix

“Aptix is a very convenient solution for us to manage our construction sites,” said Benjamin Niederkofler, CEO of Alpenbau. “One of the advantages of Aptix is that you can directly load 3D models onto machines that are equipped with machine control systems. This means that you always have the possibility to monitor the site from the office. This is a very important and fundamental tool for us to remotely monitor a construction site.”

Aptix consolidates data from different contractors and machinery, regardless of the manufacturer or operating system, and provides a comprehensive view of project performance. Senior leaders can access essential metrics in real time, such as work progress, fuel consumption, and carbon emissions, improving the ability to make informed decisions.

Control, Collaboration, Clarity  

Throughout every stage — from planning and design to actual construction — the platform supports automatic workflows that deliver designs to machines and collect telematics data without manual intervention. This automation reduces the risk of missing information and helps maintain clear communication among stakeholders.

A joint effort of this scale requires constant collaboration among contractors, local authorities and other stakeholders. The Aptix platform helps facilitate transparency in workflows by allowing access to daily productivity reports and construction data, supporting open cooperation and oversight for both project managers and crew.

“Recently it has become increasingly important that we create transparency and co-operation on this construction site and share productivity daily with construction management or even with our customers,” said Niederkofler. “Having this transparency across the entire construction site is a decisive advantage.”  

Andrea Marzi, technical director at Strabag Italy, added, “This unique platform allows all parties involved in the project to access all relevant construction information and data.”  

Once completed, the Perca Bypass is expected to generate new economic opportunities for the region. Project leaders say that by adopting innovative digital workflows and centralized data management, they are able to direct complex operations more effectively and deliver the project with increased speed and accuracy.
