ISOSISM LRB for LRT Project Jakarta, Indonesia

The synergy among FPC Italia, Freyssinet Total Indonesia and Freyssinet TD scored a great success for the seismic isolation of the Light Rail Train Project in Jakarta, Indonesia. The technical support provided to the local main contractor PT Adhi Karya and the French Consultant SISTRA, to define the best solution for limiting the maximum horizontal force transmitted to the foundation, has played a significant role in the choice of ISOSISM® LRB isolators.

FPC Italia got the order for the supply of the first nos. 2.788 ISOSISM LRB 0.4-10 385x90 and nos. 136 ISOSISM LRB 0.4-10 510x210 produced in natural rubber compound with Nominal Shear Modulus G=0,4 MPa and internal lead core. The Lead Rubber Bearings are designed and quality controlled by FPC Italia and manufactured in FPC Rubber factory.

The first lot of Nos. 600 pcs. has already been shipped to the job site after passing the Type & Production tests carried out at our ISOLAB laboratory in accordance with EN15129 standard. The 20% of the production was tested for delivering the CE certified LRBs.

The isolators are equipped with upper wedge steel plate suitable to adjust the various slopes of the structure.

The project, with more than 40 km length, is the first phase of LRT Jakarta and it is expected to be opened by the middle of 2018.
