Pursuant to the Government's Decree No. 209/2004/ND-CP of December 16, 2004, on quality management of construction works;
The Ministry of Construction guides geo-technical surveys in service of selection of construction locations and designing of works as follows:
I. GENERAL PROVISIONS
1. Scope of regulation.
This Circular provides guidance on geo-technical surveys in service of selection of construction locations and designing of works irrespective of their investment capital sources, and defines responsibilities of organizations and individuals involved in those surveys.
2. Interpretation of terms.
In this Circular, the terms below are construed as follows:
a/ Geo-technical survey (hereinafter referred to as survey) means part of construction survey conducted to assess the geo-technical conditions, anticipate their changes and impacts on construction works in the process of their construction and use.
Geo-technical survey includes geo-technical survey and geo-technical observation.
b/ Geo-technical conditions include topographical and geo-morphological characteristics; geological structure; tectonic characteristics; hydro-geological characteristics; hydro-meteorological characteristics; petrological composition; physical-mechanical features of soil and rock; and unfavorable natural and geo-technical processes.
c/ Survey site means the place where, during a survey, drilling, excavation and field test (penetration, cut, static compression, transversal compression, permeation experiment, etc.), geo-physical measurement' are carried out.
3. Survey tasks shall be drawn up by design contractors or construction survey contractors at the request of investors. Separate survey tasks shall be drawn up for the selection of construction locations or the designing of works.
Investors who fully meet relevant capability conditions under regulations on construction survey or construction designing of works may themselves draw up survey tasks.
4. Contents of survey tasks shall comply with Article 6 of the Government's Decree No. 209/2004/ND-CP of December 16, 2004, and Points 2.2.1 and 2.3.1., Section 2, Part II of this Circular. Survey tasks are subject to approval by investors and serve as a basis for making plans on survey techniques.

Plans on survey techniques must be compatible with the approved survey tasks and conformable with applied standards and must take into account the volume and nature of survey jobs, the extent of research and complexity of the natural conditions of the survey area or site.
7. Major contents of a plan on survey techniques:
- Grounds on which the plan is made, such as characteristics of the to be-constructed work, survey tasks, geo-technical characteristics, and the extent of existing research on the geo-technical conditions of the construction site;
- Composition and volume of survey work;
- Methods and equipment to be used;
- Applied standards;
- Organization of implementation;
- Implementation schedule;
- Methods of protecting technical infrastructure facilities and related construction works;
- Measures of protecting the environment: water sources, noise, exhaust gas, etc.;
- Cost estimate of survey work.
The contents of the approved plan on survey techniques must be reflected in the survey contract.
During the survey process, if detecting abnormal factors, the survey contractor may propose adjustments or supplements to the contents of the plan on survey techniques without changing the approved survey tasks. Proposals of the survey contractor are subject to approval by the investor.
8.
