ECONOMIC AND TECHNICAL STANDARDS

CONSTRUCTION OF THE NATIONAL GRAVITY NETWORK
(Issued together with Circular No. 09/2010/TT-BTNMT dated July 1, 2010 of the Ministry of Natural Resources and Environment)

Part 1.
GENERAL PROVISIONS

1. Scope of Regulation: The economic and technical standards for constructing the national gravity network apply to the following tasks:

1.1. Selecting points;

1.2. Pouring and burying markers;

1.3. Building retaining walls (pouring concrete);

1.4. Testing machines;

1.5. Measuring gravity;

1.6. Calculating relative adjustments.

2. Applicability: These standards apply to agencies, organizations, and individuals tasked with establishing plans, assigning schedules, calculating unit prices to prepare budgets and final accounts for the construction of the national gravity network using state funds, and other related organizations and individuals.

3. Economic and technical standards include the following component standards:

3.1. Labor technology norms: Labor technology norms (hereinafter referred to as labor norms) are the direct labor time required to produce a product (perform a work step). The content of labor norms includes:

3.1.1. Work content: listing basic operations and main operations to perform a work step;

3.1.2. Difficulty classification: basic factors affecting the performance of a work step;

3.1.3. Staffing: specifying the number of workers and technical levels required to perform a work step;

3.1.4. Norms: specifying the direct labor time required to produce a product (perform a work step): units of measurement are individual hours or group/unit product hours. A day's work (shift) is calculated as 8 hours of work.

a) Non-productive rates are expressed in fractional form, where:

- The numerator is the technical labor rate (calculated in group hours, individual hours);

- The denominator is the general labor rate, calculated in individual hours. General laborers are hired to perform simple tasks such as transporting equipment accompanying the main machine, materials, guiding the target range, communicating, leading the way, protecting, serving measurements, digging marker pits, washing materials.

b) The technical labor rate when work must be stopped due to weather conditions is calculated at a factor of 0.25.

3.2. Material and equipment norms

3.2.1. Material and equipment norms include material usage norms and tool (equipment) usage norms.

a) Material usage norms: the quantity of materials needed to produce a product (perform a task).

b) Tool and equipment usage norms: the number of shifts (time) that direct workers need to use tools and equipment to produce a unit product (perform a task).

3.2.2. The service life of tools and equipment is the expected period of use in normal production activities, consistent with the economic and technical parameters of the tools and equipment.

a) Service life of tools: measured in months.

b) Service life of equipment: as stipulated in joint circulars guiding budget preparation between the Ministry of Finance and the Ministry of Natural Resources and Environment.

3.2.3. Electricity consumption of electric tools and equipment is calculated based on the power rating of the tools and equipment, 8 hours of work in a day shift (shift), and the usage norms of tools and equipment. The electricity level in the norm tables is calculated according to the following formula:

Electricity level = (Equipment power/hour x 8 hours x number of equipment usage shifts) + 5% loss.

3.2.4. Rates for small tools and accessories are calculated at 5% of the tool rate in the tool table.

3.2.5. Rates for minor materials and losses are calculated at 8% of the material rate in the material table.

For the task of pouring markers and building retaining walls, in addition to this rate, an additional 5% material loss rate due to transportation during construction is also calculated.

- Testing level applies for one test of one group of machines and for a measurement period of six months. Testing electronic machines using the relative method, each group consists of four machines. Testing optical mechanical machines using the relative method, each group consists of five machines.

+ When machines are used for more than six months, additional testing levels are calculated according to the above principle.

+ When the number of machines changes, the level is recalculated proportionally.

- In cases where satellite gravity points use old coordinates, the selection point level is determined according to the provisions for the Base Geodetic Network Continuation work at the Economic and Technical Surveying Map Norms issued by Decision No. 05/2006/QĐ-BTNMT dated May 26, 2006 of the Ministry of Natural Resources and Environment.

- In cases where gravity measurements are taken using the relative method with only half the number of machines (four electronic machines or five optical mechanical machines), the level is calculated at a factor of 1.20 times the gravity measurement level.
