Total	12.637	12.637

Note:

The disposal quantity of surplus filling materials provided by Resident Site Staff is in tonnes (for Contract No. HY/2013/03: 29,065 tonnes). In order to convert the disposal quantity from tonnes to m³, a conversion factor is used and shown as follows:

Volume (in m³) = Mass (in tonnes) / 2.3 (in tonnes/ m³)

Where 2.3 (in tonnes/ m³) is the density of surplus filling materials provided by the Contractor

7.2.4 1.440 (in‘000m³) of excavated marine sediment (from Contract No. HY/2013/03), 12.682 (in‘000m³) of Inert C & D Wastes and 1.321 (in‘000m³) of Non-inert C & D Wastes were generated (from Contract No. HY/2013/03) in this reporting period. 12.637(in‘000m³) of Inert C & D Wastes were reused in other projects and 0.045(in‘000m³) of Inert C & D Wastes was disposed as public fill.
