ITALIA DEMOLIZIONI Chooses Doosan DX380LC-7
Published: 10/10, 2022
Newly formed demolition contractor Italia Demolizioni purchased several Doosan machines for use on a number of new contracts, the first of which is the demolition of the former Piero Pirelli Institute in Milan.
Founded in January 2022, Italia Demolizioni is owned by A.C.M., a leading regional road construction firm. This connection has allowed Italia Demolizioni to deal immediately with an important investment plan and to build a technologically advanced fleet of Doosan machines.
The company’ Doosan DX380LC-7 crawler excavator, a DX380DM-7 demolition excavator, three additional crawler excavators (DX300LC-7, DX350LC-7 and DX210-7), two DX85-7 mini excavators, and a DL250-7 wheel loader.
“We chose the Doosan brand because it is a guarantee of reliable, durable and productive machines,” says company director Ivano Perego. “They are true allies for ensuring efficiency and success on every site.”
Within a few months of opening its doors, Italia Demolizioni had won several major contracts. “That made it essential to have a fleet capable of providing maximum productivity on each site,” Perego adds.
The Doosan DX380LC-7, customized in the blue and orange colors that distinguish the Italia Demolizioni fleet, was chosen for the demolition of the former Piero Pirelli Institute which was built in the 1950s to provide training, workshops, seminars, and other events for Pirelli employees. Now abandoned, the Institute consisted of a 2-story classroom building and an adjacent structure for practical training. That comprising of a sequence of covered spaces averaging 23 ft (7m) height.
The DX380LC-7, equipped with a standard arm and a demolition grapple, was used for the entire primary demolition of the structure, producing more than 18,000 yd3 (14,000m3) of waste material. In the first phase, the DX380LC-7 tore down the central span structure adjacent to the main building. Then the perimeter walls of classroom building were taken down. This made it possible to produce enough rubble on which to elevate the excavator to easily reach the second floor.
The roof panels were then removed and the perimeter eaves were demolished. Next, the DX380LC-7 broke through the top of the roof to lighten the rafters. These were unhooked one by one from the pillars and then demolished to allow the excavator to enter the building and to proceed with the demolition. Subsequently, the slab between the first floor and the ground floor was demolished in order to completely cross the structure from side to side and complete the entire demolition keeping only the perimeter pillars on the ground floor.
The DX380LC-7, was then joined by the DX300LC-7 excavator armed with a crusher and hammer to take care of the secondary crushing of the demolished sections and a first selection of the various materials. Once this was all complete, the DX380LC-7 took care of preparing the ground for subsequent construction works. The DL250-7 wheel loader completed the work by handling and removing debris, unloading it onto a truck for transportation from site. The efficiency of the Doosan equipment allowed Italia Demolizioni to complete all demolition work in just 17 days.
