We have been equipped to install jacked underpasses since 1978. Over the years, albeit with additional implementation improvements and variations, we participated in part of the jacking work for the Rome Metro (having constructed most of the relevant structures themselves). An image illustrates work performed on 200 m of the B Line under the Tiburtina railways station in Rome. Other relevant projects include the bridge on the Lamasinata river in Modugno (province of Bari) with a crossing width of up to 70 m, all the underpasses of the doubling of the Pontremolese line and many others.
The system we adopt is characterised by a number of particular methods:
This system is unique in the market and its adoption avoids the need for temporary concrete artefacts (which would in part be abandoned in the ground and in part demolished at the end of jacking operations) and above allows for opposing elements to be fitted during the curing phase of the final castings (with appreciable savings in terms of safety overheads and lead times).
We have erected several private and public buildings, independently or by participating in a Contractor Group [Association of Contractors].
Images show the Nascimbeni nursery school in Flero (province of Brescia), for which we were awarded the construction tender contract and for which we also developed the complete project design (architectural, structural, plant) with the collaboration of selected technical consultants. This nursery school is composed of eight sections, each complete with sanitary facilities, a dedicated kitchen area and classrooms (with toilets) for teachers. The school building plant (the air conditioning system in particular) features state of the art energy-saving technology and the use of renewable energy sources (photovoltaic and geothermal).
We have built plant facilities for the production and distribution of electricity, including thermal and hydroelectric plants, power stations and substations.
The images show a number of these works by way of example:
We have performed the civil works related to a number of hydroelectric plants.
The images illustrate two of these:
