Operation & Maintenance

On track to modernize operations at one of France’s largest airports

From an operational point of view, we often compare the operation of an airport to that of a miniature city. The diversity of services, most of which are invisible to the majority of travellers, are in fact as varied and vital as the services provided by cities to their residents. In addition to the mobility, catering, accommodation, lighting and air-conditioning services required for passenger comfort, there are the highly regulated functions of air transport. Maintaining all these services in good […]

Extending the life of a viaduct in the Middle East

A veritable feat of engineering, a colossal bridge in the Middle East plays a vital role in the region’s economic development. Every day, tens of thousands of vehicles use this strategic route. Renovate rather than rebuild As the structure has reached the mid-point of its projected life cycle, an extensive assessment and maintenance program has been launched.Egis was entrusted with the project of securing the structure by proposing the installation of a digital twin with two objectives: Diagnose every disorder […]

Using digital models to operate an urban highway in Australia

Between 2016 and 2023, a 33 km motorway network, including 22 km of tunnels and numerous junctions, was opened in a major metropolis. This project has significantly reduced urban and suburban traffic congestion, while improving air quality by shifting surface traffic to underground tunnels. The network operator is responsible for maintenance, incident management, and the replacement and upgrading of all equipment, including tunnel equipment. To optimize operations, Egis set up an interconnection between the BIM models used to build the […]

Maintenance support platform for urban road tunnels in Switzerland

Located in the heart of a major European city, this 235-meter-long, two-tube tunnel is a critical node for the flow of road traffic. It was built using BIM methodology and designed from a 3D digital model. Egis has developed a preventive and curative maintenance platform for the tunnel operator. This platform takes full advantage of the digital models created during the construction phase. One of the main challenges in managing this tunnel is to keep the lighting, signalling and ventilation equipment […]

Satellite remote sensing of pavement disorders on a freeway in Turkey

Egis is co-operating on a 428 km freeway, including one of the world’s four largest suspension bridges (3 km) and more than 6 km of tunnels. The infrastructure will be commissioned progressively between 2016 and 2019. One of the main challenges in operating this motorway network is to establish a sustainable organization to guarantee user safety and the smooth flow of traffic, based on : efficient traffic management, rapid response to incidents and ongoing maintenance. Egis has developed and implemented […]

Platform for secure maintenance & operation of an urban highway in Australia

An operator of a complex 24 km urban motorway network consisting mainly of critical infrastructure and 15.5 km of tunnels is responsible for traffic and incident management, as well as network maintenance. EGIS has set up a digital operating twin, a single geolocated repository representative of the entire infrastructure. The aim is to plan and monitor maintenance operations, manage traffic and simulate critical events such as flooding. This digital twin is based on a web platform that aggregates geospatial data […]

Supervision platform for a sensitive structure in the Philippines

A 5.3km-long double bridge, opened in 1977 and designed to withstand extreme seismic events, underwent a detailed assessment of its condition and the defects affecting each of its components. Egis produced a functional model of the bridge, which was then integrated into a digital operating twin. This technology makes it possible to supervise the overall condition of the bridge, analyze defects in several parts, and plan maintenance operations on each element. A dynamic 3D synoptic of the bridge, combined […]

Implementation of the Smart Vigie tool to operate a digital twin

Egis has been active in Ireland’s transport sector for over thirty years, and is involved in the operation and maintenance of rail, road and mobility services throughout the country. A mobility company that has worked with Egis has already implemented new processes for rolling stock, and now wants to focus on infrastructure. The main challenge concerns the cleanliness and condition of the infrastructure, with the aim of reducing financial penalties, improving collaboration with the subcontractor, and reassuring the transport authority […]

Point clouds for freeway operations in the UK

Egis has been operating one of Europe’s busiest freeways since 2009. This infrastructure is the subject of a major annual investment program to renew and improve the quality of service provided by this network. A critical network 440 km long, it carries 15% of all UK motorway traffic and, on its busiest section, is used by over 250 000 vehicles a day. A complex infrastructure The operated network comprises: 5 tunnels, nearly 2,500 structures, including bridges, culverts and overhead gantries, and […]
