Agree to use cast in-situ fence at St.5+570 to 5+590 which under Al-Qadima Bridge instead of precast fence due to the height is not enough and to expedite the work but the decorative part of the walls and columns should be maintained and contractor shall submit samples of different material which will use for decorative parts. The height and length shall be maintained as per architecture requirements. The important part is the strength of the walls, columns and footings should be crashed rated fence. No positive change order.
