Strutting Technology for Italian Job
Groundforce, has supplied a modular proprietary excavation solution for one of Italy’s most prestigious construction jobs – the new M9 Museum in Mestre.
The area where the M9 is being built covers 9,000 m² and includes a former 16th century Benedictine monastery, the former local police headquarters and a building with offices and businesses.
Groundforce supplied its MP250’s props for the construction of two underground levels, which required excavating to a depth of some 9 metres below the ground level, retained by concrete diaphragms.
Given the considerable excavation depth, it was necessary to construct earth retention works with concrete diaphragms. Installing Groundforce props helped avoid having to create a great number of tension members.
Using a modular hydraulic shoring system also offered significant advantages and cost savings over traditional steel methods by reducing the hours required for the works - the first installation of props at Mestre was completed in just one day.
The MP250’s props were equipped with 1,220 mm “super-extension” that are used where adequate lighting must be covered without intermediate supports. In this particular underground environment, they are 30 metres long. In addition, the modular composition of the tubes greatly facilitates installation, removal and transport.
The second installation of 4 Groundforce struts was delivered to the building site in mid-May for completion of the excavation. Using this technology recommended by Sogen S.r.l. (a Padova consulting company specialising in geotechnical and structural engineering) proved to be a solution that was more advantageous than the initial project that proposed excavating with walls retained by traditional struts and walls retained with tension members.
Delivery of TSHD “Hondarra”
The delivery of the 1.200 m³ TSHD “Hondarra” is the 4th TSHD built in the Spanish-Dutch cooperation between Astilleros de Murueta and Damen Dredging Equipment.
The hopper dredger will perform maintenance dredging duties in the harbour of Bayonne and supply sand to the nearby beaches. The “Hondarra” is the first dredger of the CCI Bayonne Pays Basque.
