Scope of application:

To be applied to all signals which have been marked at a depth > 1-3m from the water bottom (in calm waters).

Contents of work:

- Preparing, inspecting and taking safety measures, divers with diving equipment and engineering equipment to poke, using sand and mud blower and sucker to dig at the point where signals have been marked in accordance with technical requirements at a depth > 1-3m until the signals come out.

- Inspecting and identifying signals: if they are magnetic objects or boms, mines and explosive objects which are safe for collection and transport, handle them safely, lift them ashore and take them to the prescribed place. If they are boms, mines and explosive objects or strange explosive objects and unsafely for collection and transport, they must be destroyed by explosion on the spot. The destruction of underwater boms, mines and explosive objects on the spot shall have specific norm.

Unit: 1 signal

030.0800. ON-THE-SPOT DESTRUCTION BY EXPLOSION OF UNDERWATER BOMS, MINES AND EXPLOSIVE OBJECTS

Scope of application:

To be applied to on-the-spot destruction of detected boms, mines and explosive objects but unsafe for lift and collection (in calm waters).

Contents of work:

- Preparing destruction equipment, shelter, detonating and guarding stations; wrapping, laying explosive amount and installing fire equipment.

- Preparing, inspecting and taking measures to ensure safety, guarding and providing for signals.

- Carrying out detomation of boms, mines and explosive objects in accordance with the approved techniques and plans.

Unit: 01 bomb, mine or explosive object

ANNEX

NORM OF COST OF INVESTIGATION AND SURVEY TO PREPARE PLAN AND ESTIMATE; INSPECT QUALITY OF DETECTION AND DESTRUCTION OF BOMS, MINES AND EXPLOSIVE OBJECTS

Scope of application:

- Investigating and surveying to prepare plan and estimate for detection and destruction of boms, mines and explosive objects.

- Assessing plan and estimate of detection and destruction of boms, mines and explosive objects.

- Inspecting and appraising quality of works of detection and destruction of boms, mines and explosive objects.

Contents of work:

- Investigating and collecting data on topography, geology, hydrology, population and reality of bombs and mine in the areas. Surveying signal density, types of boms, mines and explosive objects in the basic areas to prepare plans and estimate (practicing the detection and destruction of boms, mines and explosive objects at surveying locations, each location usually has a size (20x20)m. The total surveyed areas account for 1% of the total area of works of detection of boms, mines and explosive objects

- Preparing and assessing plan and estimate of detection and destruction of boms, mines and explosive objects for works or works items.

- Inspecting and appraising quality of works of detection and destruction of boms, mines and explosive objects.

Unit: percentage over value of approved estimate of building and installation

Note: The cost for appraisal of plan and estimate is prorated as per value of total estimate:

1. When the total value is less than 1 billion dong, then the cost is 0.5%

2. When the total value is less than 3 billion dong, then the cost is 0.3%

3. When the total value is from 3 billion dong or more, then the cost is 0.2%
