The rip-rap and backfill parts of the project, which started in 2012, have been completed in an average period of 9 months without an occupational accident. In manufacturing of rip-rap, the rock blocks with a minimum diameter of 1 meter from the Marmara island were lined up in a berm position by handling machines and their fortifications were completed. Afterwards, backfilling operations were completed by making the controlled filling with recyclable wastes brought from various districts of Istanbul.
