In the context of rapid urbanization and industrialization, land filling for infrastructure development is the most critical initial step of any project. However, it also brings challenges related to quality control, material quantification, and environmental protection. The service of surveying and assessing the location, area, and volume of backfill solid materials acts as a “technical arbitrator,” ensuring transparency, accuracy, and legal compliance. The assessment results serve as an important basis for state management, dispute resolution, and inspection of compliance with regulations on land, construction, and environmental protection.
SURVEY AND ASSESSMENT OF LOCATION, AREA AND VOLUME OF BACKFILL SOLID MATERIALS
1. IMPORTANCE OF BACKFILL SOLID MATERIAL ASSESSMENT
The assessment of the location, area, and volume of backfill solid materials is conducted for various purposes, including:
- Firstly, to accurately determine the extent of the backfilling area in order to verify whether the activity is carried out within the permitted boundaries. In many cases, backfilling may encroach upon public land, agricultural land, or land owned by other individuals.
- Secondly, to evaluate the volume of backfill materials to determine the actual scale of the activity. This is particularly important in cases involving violations such as illegal mineral extraction, unlawful dumping, or unauthorized land filling.
- Thirdly, to support inspection, supervision, and violation handling. Competent authorities may rely on assessment results to impose administrative penalties, require remedial actions, or handle cases in accordance with legal regulations.
- Fourthly, to serve as a basis for resolving civil disputes related to land, land use rights, or damages caused by backfilling activities.
2. FIELD INSPECTION PROCEDURE
Based on actual site images recorded by on-site engineers, the inspection process is carried out rigorously through the following steps:
2.1. Assessment of Location and Area Using Modern Surveying Equipment
Using equipment such as total stations and RTK GPS systems, SVG Engineering accurately determines the coordinates of boundary markers.
-
Boundary determination: Ensuring that the backfill area matches the design drawings and cadastral survey records.
-
Establishment of control network: Serving as the basis for calculating elevations before and after dumping/filling activities.
2.2. Inspection of Material Type and Impurity Composition
This is the most critical step in determining the nature of “backfill solid materials.” SVG Engineering’s construction engineers carry out the following:
-
Field sampling: Samples are collected from various locations within the dumping site, properly bagged, sealed, and signed by relevant parties.
-
Impurity analysis: Examination of the proportion of waste materials such as debris, decayed wood, plastics, or other components that may be harmful to the environment and subgrade structure.
-
Mechanical and physical testing: Determination of moisture content, particle composition, and compressibility/settlement indices.
2.3. Measurement and Volume Calculation
The volume is calculated based on the difference in elevation between the natural ground surface and the surface after backfilling.
-
Grid method: Dividing the area into small grids for detailed calculation.
-
Cross-section method: Commonly applied in road embankment or dike construction.
-
Use of specialized software: Data collected from RTK surveying equipment is imported into dedicated software to generate the most accurate volume calculations.
3. EQUIPMENT USED IN BACKFILL SOLID MATERIAL ASSESSMENT
To ensure results with high legal validity and reliability, the use of specialized equipment is essential:
-
RTK GPS system: Enables coordinate measurement with millimeter-level accuracy in real time, even in complex terrains such as mountainous areas or large dumping sites.
-
Compaction testing device (K): Used to verify whether the backfill material has been compacted to meet design requirements.
-
Specialized sampling equipment: Ensures that collected samples retain their natural structure for accurate analysis of impurity composition.

The sealing of samples in labeled yellow plastic bags serves as evidence of transparency and objectivity, preventing any sample tampering before they are transported to the laboratory.
- Images of SVG Engineering’s construction engineers using RTK GPS equipment to measure elevations across material stockpiles. This process helps accurately determine the peak elevation and the coverage area of the material mass.
- The assessment of the location, area, and volume of backfill solid materials is a highly technical activity that requires a combination of modern surveying methods and specialized knowledge in land administration, construction, and environmental fields. Through this process, competent authorities can accurately determine the scope and scale of backfilling activities, thereby making appropriate management decisions.
- In the context of rapid urbanization and infrastructure development, strict control over land filling activities is essential. With the support of reputable organizations such as SVG Engineering, this not only ensures legal compliance but also helps protect land resources and the living environment, contributing to sustainable development.
