Vietnam: Layout of economic – technical norms for dredging of marine works

Specifically, economic – technical norms for dredging of marine works are arranged into groups, types of work, are numbered and organized into 02 chapters:

- Chapter I: General provisions

- Chapter II: Economic – technical norms for dredging of marine works.

+ Submarine grab dredge;

+ Transportation of dredged materials by self-propelled barges;

Each norm comprises a summary of work components, technical conditions and construction conditions, and is measured in an appropriate unit for dredging and transportation activities.

Concurrently, Circular No. 44/2018/TT-BGTVT also stipulates that components which are consumed within a specified norm shall be defined according to the following principles:

- Main and marginal labor consumption rate shall be determined by the number of working days specific to the average ranks of direct construction workers;    

- The construction equipment and machinery operation rate shall be determined by the number of shifts on which construction equipment or machinery is operated (construction equipment or machinery which are those incurring a large proportion of costs to total equipment or machinery cost per a workload unit, a work item or a construction structure. For the purposes of this Circular, construction equipment or machinery include construction barges, grab dredge, self-propelled barges with open decks, etc.);

- The operation rate of other construction equipment and machinery shall be determined by the ratio (in percent) of operation of these equipment and machinery to total cost of operation of main equipment or machinery (these construction equipment or machinery which are those incurring a small proportion of costs to total equipment or machinery cost per a workload unit, a work item or a construction structure. For the purposes of this Circular, these construction equipment or machinery include towboats, motor boats used for installing buoys, construction site positioning equipment, etc.).

More details can be found in Circular No. 44/2018/TT-BGTVT of the Ministry of Transport of Vietnam, which takes effect from October 01, 2018.
