Building Information Modeling/Virtual Design & Construction
A Skanska-led consortium was responsible for financing, construction, and operation and maintenance of the 61-kilometer, 6-lane highway, Autopista Central, the main artery of the Santiago toll road system. The road is equipped with an advanced free-flow toll system that enables each driver to pass the toll stations without stopping. Tolls are collected by the Special Purpose Company, Autopista Central de Chile, via a 24-hour service centre that monitors the highway and provides emergency and breakdown services as well as collecting tolls for 140,000 journeys a day.
Autopista Central is the largest infrastructure city road project in Chile, and is a part of the Pan American corridor linking Chile with South American countries along the Pacific Ocean. Before the highway opened, crossing the city took more than an hour. Now it’s only 15 minutes.
In 2010 Skanska sold its 50-percent share in the Special Purpose Company. The buyer, Alberta Investment Management Corporation (AIMCo), is one of Canada's largest institutional management firms managing funds on behalf of the Province of Alberta, certain public pension and endowments. Skanska received a total corresponding to SEK 5.4 Billion of proceeds resulting in a net profit of SEK 4.5 Billion.

Sustainability At Autopista Central, Santiago’s urban highway, Skanska has encouraged all the partners in the SPC set up to deliver and operate the road to prioritize sustainability and environmental protection, and to meet the requirements set out in the Environmental Impact Assessment prepared by Chilean EPA ( CONAMA ). Environmental successes fall into four main categories:
Public environment improvementsPublic areas next to the highway have been improved and made safer for local residents by landscaping, maintenance and installing lighting. 110 hectares of parks and gardens have been created on land previously used as illegal dumping grounds. The improvement of nearby residential areas has made inner city neighbourhoods more attractive to live in and may indirectly support the local authority's efforts to limit urban sprawl.
Atmospheric pollution reductionAtmospheric pollution is a serious issue in Santiago and the local authorities have implemented a plan to improve air quality in the city. Autopista Central has helped by reducing vehicle journey times and eliminating traffic jams along the route.
Noise pollution reductionTo minimise disturbance, Autopista Central has bought and customised special equipment and machinery that does not emit noise over a certain level. Other measures include acoustic barriers to reduce the traffic noise.
Learning from good practiceHighway safety, community integration, improving neighbouring environments and minimising the environmental impact of the highway have been vital to the success of the Autopista Central project. All these activities have been integrated into the Autopista Central company’s long-term business strategy, which minimises risk, promotes a good business environment and benefits the local community.
The design and construction of Autopista Central, the urban highway created by a Skanska-led consortium in Santiago, Chile, were major challenges, as the highway runs within metres of hundreds of thousands of homes.Co-ordinating many different bodies – 14 different municipalities, some 15 utility companies and 12 or 13 police departments, plus the ministry of transport – was vital. Within 3 blocks of the highway lived 500,000 people who would be affected by the construction. So managing all of these bodies in a way that allowed the construction team to relocate utilities and divert 70,000 cars a day to meet the needs of construction was also a major undertaking.It was achieved by close communication with local residents and the support of Javier Villanueva of the Ministry of Public Works, who went out to meet local people to consult them about their needs and to reassure them about the benefits of the highway. He says:“It is difficult to build a highway through an urban area. People accepted the disruption because they believed the road would bring a better life.”The importance of the development to the city was recognised by the incoming President of Chile, Michelle Bachelet, who was present at the inauguration of the final sections of the road in May 2006.
Motorway construction was undertaken and managed in a Joint Venture between Skanska LA, ACS Dragados , and two local Chilean construction companies Brotec and Belfi.
• 61 km of motorway • 12 overpasses and 31 underpasses• 6 motorway interchanges• 4 bridges• 2 emergency service areas • 1.2 km of tunnel• 3.1 km of semi-covered and covered trench. The motorway is equipped as follows:• 155 emergency roadside telephones • 900 traffic logging counters• Two high-speed weigh-in-motion sites • One traffic control room, manned 24/7 • One fibre optic-based communications backbone installed along the length of the motorway to carry voice and data • 52 Electronic sign panels• 100 cameras along the road• 150 data collection stations
The highway is one of the worlds most intelligent, supported by advanced systems for both toll collection and traffic monitoring and installed in only the third city in the world.
The highway's cash-less freeflow toll system automatically logs and charges for 140,000 journeys every day via an electronic tag in each vehicle, without having to stop the vehicles. To collect the revenues, Autopista Central issues 300,000-400,000 invoices per month.
Closed circuit TV cameras monitor every centimeter of the highway, checking for a wide range of incidents ranging from breakdowns to accidents and crime, so that help can be sent where it is needed.
