The upgrade of the KLOE detector at the DAFNE Phi-factory foresees the insertion of a new Inner Tracker device around the interaction region, composed by four tracking layers with diameters from 260 mm to 410 mm and an active length of 700 mm. Each layer is realized as a cylindrical triple-GEM detector, a solution that allows to keep the total material budget under 2% of X0, of utmost importance to limit the multiple scattering of low-momentum tracks at KLOE-2, and to minimize dead spaces. The peculiar readout pattern with XV strips provides a spatial resolution of about 200 um on both views. A dedicated readout system has been developed within the KLOE-2 collaboration. It is composed by a digital readout front-end card based on the GASTONE ASIC and a General Interface Board with a configurable FPGA architecture and Gigabit Ethernet. The three innermost layers have been built and extensively tested with a beta source and cosmic-rays, and the construction of the fourth layer has started. The insertion inside the KLOE apparatus is foreseen in spring 2013. The construction procedure and the results of the validation tests will be reported.
