The hydraulic filling of sea sand should be adopted under the elevation +, which is specified in the tender documents. But based on our site investigation report, we propose to use sweet water sand instead of sea sand for these following reasons: Proposed Design Philosophy, Construction, Installation and Monitoring Method As per of Section of ITB 2 2 (1) Fine grade and high mud content of the sea sand。 Proposed Design Philosophy, Construction, Installation and Monitoring Method As per of Section of ITB 1 1 Proposed Design Philosophy, Construction, Installation and Monitoring Method ( as per of section ) 1. Source of borrows pit indicating the location and quantity We have license given by Vietnam authority to exploit a quantity of 8, 400,000 m3 in Nha Be river and the location is in Nhon Trach district, Dong Nai province. 2. Physical proprieties of proposed fill material The sampling test of sand proposed to use is carried out
