Binishells are reinforced concrete thin-shell structures that are lifted and shaped by air pressure. They were invented in the 1960s by Dante Bini, who built 1,600 of them in 23 countries.Colour photograph of a distinctive architectural feature known as a Binishell on the Gippsland campus. The large reinforced concrete dome is shaped and lifted by air pressure. Its inventor, architect Dr. Dante Bini, directed the construction of the Binishell in December 1979. The eleven metre high binishell, used 300 tons of concrete and reinforcing steel, was inflated by a large membrane in around one hour, using Dr. Dante Bini's ferrocement method. The Binishell was used as a place for exams and graduations. Reactive clay in the soil caused the footings of the binishell to twist, subsequently causing the shell to crack. The resulting damage diminished structural integrity, resulting in the Binishell not being used in 2004 and early 2005 while a new structure support was installed. Normal use of the building was resumed in Semester 1 2005. Eventually the external thermal membrane started to fail, and on 14 February 2009, the Binishell was demolished, with new auditorium built at the campus for classes, graduation ceremonies, exams and conferences.gippsland campus collection, binishell

Diamond Creek Bini Shell Community venue Built in 1979 in Diamond Creek opposite the hotel using a construction method invented by Dante Bini. A net of flexible steel rods were laid on the building’s circular base, on the top of a fabric bladder. Concrete was poured onto the mesh and a sealed cover laid over the concrete making a sandwich of cover, bladder and mesh. Compressed air was pumped into the bladder and the sandwich slowly began to rise and become a massive self-supporting dome. The inflation of the dome attracted crowds of onlookers many from various technical schools, VIPs and the famous football doctor, Donald Cordner. An opening night dinner was held to celebrate the construction and the Diamond Creek Bini Shell was used as a community venue for over ten years including for the Town Fair. The Shell was closed for safety reasons after a Bini Shell in another State had chunks of concrete fall off the dome due to a construction fault. At the Diamond Creek Town Fair in 1991 the demolition of the Bini Shell was an item on the Town Fair’s program.

In 1978 Diamond Valley Shire recognised the need for a new public hall in Diamond Creek. Council considered the Bini shell form of construction which was in operation overseas and in use in New South Wales as libraries, gymnasiums, sports centres and multi-purpose centres. The Council gave the go-ahead. A site was chosen opposite the Hotel and close to the railway line. One day in - the following year, in 1979, activity stood still in Diamond Creek as school children and other excited spectators watched the one-hour inflation of the Bini Shell. This unusual method of construction was invented by Italian industrial designer and architect Dante Bini. The construction pneumatically raises a level of reinforced concrete from ground level which has not been set, using an internal balloon. The inner membrane inflates and compresses the mesh and concrete against the outer membrane. A net of flexible steel rods was laid on the building’s circular base, on the top of a fabric bladder. 300 tonnes of reinforced concrete were poured onto the mesh and a sealed cover laid over the concrete making a sandwich of cover, bladder and mesh. Compressed air was pumped into the bladder and the sandwich slowly began to rise and become a massive self-supporting dome. After inflation and removal of the outer membrane workmen filled in any holes. It was some days before pneumatic drills pecked out the first opening. The ceiling of the concrete dome was lined with fluffy insulating material. The dome was 36 metres in diameter at the base and 12 metres high in the centre with a usable floor space of 670 square metres. An opening night dinner was held to celebrate the new facility on March 12, 1980. Shire President Ron Pata made a speech and unveiled a plaque. It was the first public building in Victoria to be erected using the Bini Shell design method of construction The facility could cater for up to 400 people and in 1980 a fee for use was $100 for up to 200 people, $150 for up to 300 people and $200 for up to 400 people. For the next ten years or so, locals attended the hall for marital arts classes, basketball and netball games and school discoes and various other activities. After pieces of concrete fell off a Bini shell interstate due to a construction fault, the Council closed the centre. Demotion took place during the Diamond Creek Town Fair in 1991, as part of the annual Town Fair’s program. Research by L.P.
