60 years on the road
one direction
the future

From post-earthquake reconstruction to major international infrastructure, Unimpresa is the partner that turns territories' vision into lasting works.

Infrastructure works for public bodies and major clients

Unimpresa's roots lie in a family story that began in 1961, when Guido Rainone and his brother Ciro founded Impresa di Costruzioni Rainone. Since then, entrepreneurial courage, technical strength, and vision have guided every step, on site and beyond.

METHODS AND PROCESSES

Deep pavement
investigation
technologies

The rehabilitation of the Bole Airport New Runway in Addis Ababa involved the use of advanced technologies for structural pavement diagnosis, including the Heavy Weight Deflectometer (HWD) and Ground Penetrating Radar (GPR), used by Unimpresa S.p.A. in partnership with Dynatest Italia and under the scientific supervision of Prof. Alessandro Marradi. When cracking or deformation is present, the runway condition is verified through an on-site investigation campaign in which the HWD plays a central role: a mobile lab applies an impulse load that simulates the passage of an aircraft wheel and measures, via geophones, the surface deflection at various distances from the load axis. Analysis of the deflection basin makes it possible to estimate the Dynamic Elastic Moduli of the various layers, including subgrades, a crucial piece of information for runways subject to very high vertical, tangential, and torsional stresses.

Geomechanically
reinforced earth walls

Reinforced earth, made up of reinforcement geogrids and fill soil, are retaining structures (NTC 2018) used in geotechnical and road engineering to build embankments with sub-vertical slopes, i.e., with much steeper gradients than normal earth embankments (<= 45 degrees). On the new Epheson-Ataye-Mehal Meda road this technology was chosen to solve two critical issues: very steep natural slopes and the strong cantilever of the road embankment beyond the slope profile. The use of reinforced earth made it possible to limit the embankment extension toward the valley, avoiding excessive cut on the uphill side and the need for enormous volumes of fill material to reach the design road level.

concrete
monoliths

Throughout the first decade of the 2000s, the scale and complexity of the road works entrusted to CO.GE.R, part of the Unirainone group, required procedures for building "box" structures, i.e., concrete monoliths cast on site off-line and then inserted into the road and/or motorway embankments to be crossed, by pushing with hydraulic jacks, to allow the traffic in service to be maintained. The same technology was also adopted for road and/or motorway underpasses and to allow the passage of water supply lines.

A3 NAPLES
POMPEI SALERNO

During the first ANAS lot for the construction of the third lane of the A3 Napoli-Pompei-Salerno, an off-line reinforced concrete box structure about 60 m long was built, configured as a "micro tunnel," to ensure the continuity of the Circumvesuviana railway line near the Pompei interchange (Naples direction). The monolith was built on site and then pushed into the motorway embankment using hydraulic jacks (oleodynamic thrust), allowing the A3 vehicular traffic to remain in service throughout all launching phases.

VIEW PROJECT

concrete
monoliths

During the long urbanization works at Parco Talenti in Rome, to protect the 2 m diameter steel water pipeline that crosses Via di Casal Boccone, a large reinforced concrete box structure was built. At the end of that road, before entering the roundabout where Via Ojetti joins, a structure known as the "Cecchina Bridge" was built to cross the "Fosso della Cecchina," part of the stormwater collection system for Parco Talenti. This structure, whose abutments rest on large-diameter piles, has an 11 m span and a width of about 25 meters, including service tunnels and sidewalks. - The Parco Talenti works required complex excavation phases during which archaeological findings emerged, concerning the wall perimeter of a Roman-era villa. CO.GE.R. carried out a targeted and detailed survey and the related drawings for the Works Management, for the design of protection works for the site and for its location. - These protection works executed by CO.GE.R. consisted of backfilling the excavations, proper compaction, and the construction of a reinforced concrete slab of adequate thickness to safeguard the finds, as the area is subject to vehicular traffic.
