present market Difference
in % Remark
1 Guinting on Concrete 1057.00 p/sqm 1477.00 p/sqm 39.73 Higher rate due to distant location and
specialized nature of work
2 25mm Mastic Asphalt 420.00 p/sqm 504.00 p/sqm 20.00 Due to increase in cost of mastic
asphalt and remote location of bridge
3M-30 Grade concrete for jacketing
