The synergy among FPC Italia, Freyssinet Total Indonesia and Freyssinet TD scored a great success for the seismic isolation of the LRT Project in Jakarta. The technical support provided to the local main contractor PT Adhi Karya and the French consultant SYSTRA, 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 of the first nos. 2 788 ISOSISM® LRB 0.4-10 385×90 and nos. 136 ISOSISM® LRB 0.4-10 510×210 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 isolators are equipped with upper wedge steel plate suitable to adjust the various slopes of the structure. The first lot of 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 EN015129 standard. The 20 % of the production was tested for delivering the CE certified LRBs.
