ECONOMIC – TECHNICAL NORMS

FOR DREDGING OF MARINE WORKS  
(Issued together with the Circular No. 44/2018/TT-BGTVT dated August 03, 2018 of the Minister of Transport)

Chapter I

GENERAL PROVISIONS

I.1. Subjects of application:

Economic – technical norms for dredging of marine works are applied to domestic and foreign entities, organizations and individuals related to the dredging and overhaul of shipping channels, internal waters and territorial waters within the seaport’s water area.

I.2. Bases for setting up these norms:

+ The Government’s Decree No. 32/2015/ND-CP dated March 25, 2015 on the construction cost management;

+ The Circular No. 06/2016/TT-BXD dated March 10, 2016 of the Ministry of Construction guiding the determination and management of construction investment costs;

+ The Circular No. 47/2015/TT-BGTVT dated September 14, 2015 of the Minister of Transport prescribing the scope and responsibilities of seafarers, operators and minimum safety requirements concerning personnel aboard the inland watercraft;

+ The Circular No. 04/2017/TT-BGTVT dated January 20, 2017 of the Minister of Transport on amendments and supplements to certain articles of the Circular No. 47/2015/TT-BGTVT dated September 14, 2015 of the Minister of Transport regarding the scope and responsibilities of seafarers, operators and minimum safety requirements concerning personnel aboard the inland watercraft;

+ Reporting and measurement data used for setting up economic – technical norms for dredging of marine works.

+ Certain legislative documents and other documents concerned.

I.3. Contents of these norms:

Economic – technical norms for dredging of marine works shall be constituted by the following components:

- Labor consumption rate:

This refers to the number of working days of direct construction workers and workers providing construction support services.

The number of working days includes those days during which both main workers and marginal workers spend on carrying out and completing a construction workload unit from the preparation stage to the stage of completion and clean-up of the construction site.  

Worker rank refers to the average ranks of workers involved in carrying out a construction workload unit.

- Construction machinery or equipment operation rate:

This refers to the number of shifts during which both main construction machinery or equipment and auxiliary ones are directly operated to complete a construction workload unit.  

I.4. Layout of these norms:

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.

- 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.).

I.5. Instructions for application of norms:

- Economic – technical norms for dredging of marine works are bases for unit construction cost formulation, construction cost estimation and investment and construction cost management.

- In addition to the abovementioned interpretations and instructions, in these norms, there must be specific interpretations and instructions for groups and types of dredge work and transportation in conformity with technical requirements, construction conditions and requirements concerning construction approaches.

Chapter II

ECONOMIC – TECHNICAL NORMS FOR DREDGING OF MARINE WORKS

II.1. Processes:

1. Dredging by using submarine grab dredge:

- Preparation of tools, equipment and signal buoys;

- Positioning of the construction center point and determination of excavation scope;
