The data has been updated from the reports of project as approved including dimensions of the engineering works, size of channel, barges lower case designed and calculated, system of signing buoys and slope protection. The technical design has also been updated and based on the barges as calculated and specified in the local waterways standard TCVN 5664-2009. The proposals regarding the barges calculated and channel regulations compliant with natural conditions and exploitation on the sections of river and canal that are invested and upgraded. The specific content of design: + Calculation of water level of transportation; + Calculation of size and channel elevation; + Statistics of land clearance area, estimation of cost for both site clearance ; + Proposed construction method, the construction schedule of dredging waterway; + Proposal for the method of transporting waste soil, location and scale of dump area and waste water drainage; + Proposal for the method of safety of waterway transport during the execution; + Construction of bridges and roads at rural area at site clearance for the purpose of enlarging the channels. The following work items are not shown in the design of dredging channel (which is to be shown in another separate document): + Removed obstacles from the way-leave of the designed channels; + Navigation signs for local waterways; + Report of site clearance for the purpose of executing widening of channels + Detecting and disarming unexploded mines and bombs (UXO); Mekong Delta Transport Infrastructure Development Project (MDTIDP) Main Waterway Corridors Improvementphase 2 Plus Supervision Of Phase 1+2 General Report of Dredging Waterway of Corridor No 2&3 Page 8 + Assessing the environmental impact, managing the environment during and after dredging and excavation works 1.5. WORKS LEVEL In accordance with the scope of civil works involoved, this project component belongs to the Classification IV…or belongs to the category IV as per the Appendix 1 – Chapter 5: Classifications and Grading of Construction Works – the Decree 209/2004/NĐ-CP issued by the Vietnamese Government. In accordance with the design of the civil works, the dredging channel works to level Category 3 , Table C1 – Appendix, Specification of National Engineering regarding Vietnam Building Code on Classifications and Grading of Civil and Industrial Buildings and Urban Infrastructures ) QCVN 03: 2009/BXD issued with the instruction Circular 33/2009/TT-BXD dated September 30 th , 2009; Works on dredging of waterway channels may be increased in quantities due to the slow process of deposition of fine sediments along the channels. In accordance with the regulations of Vietnam TCXDVN285:2002 concerning irrigation works, the main specifications of design of the works put out of exploitation for more than 10 years are likely to de downgraded with 1 level in the categorisation system. In conclusion, the class of waterway will be designed as class IV. 1.6.
