Lunghezza Plant | Precast Beam Plant

  • Location: Italy – Lazio – Lunghezza (Roma)
  • Section: Urban Stretch of the A24

Prefabrication is the core activity for TOTO S.p.A. Costruzioni Generali. Toto has strategically chosen to integrate the prefabrication activity in order to: manage the entire process on the progress of work , ensure product quality and develop construction techniques for the purpouse of reducing the construction time & costs, as well as logistic equipment. High quality of the product, construction methodology, engineering specialization, R&D investment, use of cutting-edge materials and, last but not least in-house production of prefabricated elements in plants specifically made on site, are the distinctive elements of this business sector. The Lunghezza plant (RM), for prefabrication of reinforced concrete beams, has been created to support the construction of an urban slip road on the stretch of the A24 in Rome. Within the prefabrication plant there are three main production lines; one relating to the construction of reinforced concrete beams, and two related to the construction of retaining walls and precast slabs for bridge decks.

  • Plant area: 3,822 m2
  • Specialized staff: 27 units
  • Planned work shifts: eight-hour shift per day
  • Prefabricated concrete production per day: 50 m3/day
  • Average daily production of beams in prestressed concrete: 1 beam/day
  • Prestressed reinforced concrete beam weight: between 75 and 103 tonnes
  • Length of prestressed reinforced concrete beam: between 13 m and 29 m
  • Average daily production of support walls and deck precast slabs : 20 elements/day

The daily production is one beam per working day.

  • It is guaranteed by the use of accelerated steam curing for accelerating the beam curing process.
  • Same is generated through a special thermal power station located on the back of the plant itself.

Therefore, it makes it possible to reach the minimum mechanical resistance required by the design prior to releasing of the prestressing cables.

Afterwards, the formorks is removed prior to start with the production cycle of the next beam element.

The beams have obtained the CE mark, i. e. the certification of conformity to European standards hence giving considerable value both to the manufactured products and to the construction methodology.
