Landbase Surveying

Land Survey And Mapping

To achieve higher standards of Structural Designs and Project Management Consultancy Report parameters, it’s always necessary to enhance the quality of Land Surveys and Soil Investigation methods which are basic needs of any Project Management Consultancy in India. For every infrastructure construction project, carrying out a survey of the proposed site and furnishing the detailed engineering report is a very much essential task.

Dhrumik Land Developers Private Limited uses all the latest technologies and equipment’s for the purpose of land survey and mapping to ensure high quality is maintained in work. Technology has helped Dhrumik Land Developers Private Limited to grow and bag elite clients. To know more about our survey & mapping work.

Survey Methodology:

We follow below mentioned Topographical/ Land Survey methodologies

1. Mobilization: This includes inspection of land survey site boundary and collection of secondary data. It covers collection of latitude and longitudes of points shown in land survey map. Fixing of a tentative location of baseline, start off meeting with a client to convince the methodology, constraints, and requirements from client.

2. Control Points: Inland/ Engineering survey it is a vital role of control points/ baselines/ traverse survey to achieve control on large surveys in roads, railways or areas. Application of high-end instruments is necessary to achieve benchmarks like DGPS or 1’ (one second) accuracy total stations.

3. Spot leveling/ L-section/ X-section/ Area Survey: Grid survey, spot level interval mentioned in the contract, future land survey would be carried and with the help of digital level, auto level, dumpy level, total station, instruments and noted in electronic field bosh or in hard copy.

4. Collection of Details: Collection of details would be existing structures like buildings, temples, mosque, huts, utilities like water supply pipeline, sewerage network, storm water line, electric line, telephone line, gas line. Mapping of underground utilities is a major aspect of a land survey which has a key role in the implementation of the project as well as project management consultancy.

5. Preparation of drawings: Drawing with the help of AutoCAD or similar software is prepared after downloading data from survey instruments like a total station, digital level or GPS with layer management and consideration of client’s requirement. Area volume and lengths are worked out as per nature of the project and the digital terrain is developed on the basis of contours and elevation.

6. Quality assurance and quality control measures: To ensure quality, it is essential to verify the drawing at a site to check the accuracy of the land survey, checking of a traverse, baseline, benchmark, and control points is a vital role in checking accuracy.

7. Final submission of report & drawings: At the end of the survey work and analysis we provide detailed engineering reports of a land survey to our clients. We make sure all the guidelines and standards are met while preparing such important report.

Soil Investigation and Geotechnical

Dhrumik Land Developers Private Limited is one of the leading geotechnical companies in Rajkot, Gujarat, India. We have a technologically advanced soil testing laboratory in Rajkot, Gujarat. We also provide geotech services in all over parts in Gujarat. We follow below steps for soil investigation to ensure accurate & reliable test results.

Field Work:

Drilling and sampling in soil & rock are carried out using rotary drilling rig. The borehole in soil is advanced using rotary drilling method, while NX size core barrel is used to drill in rock, Water is circulated to cool the drilling bit. Groundwater table is recorded after 24 hours of completion of drilling. On completion of drilling, soil samples are packed in plastic containers with proper identification tags. Rock cores are numbered and kept in core boxes.

Field Tests & a collection of Soil Samples: Standard Penetration Test (SPT) & Collection of Undisturbed Samples (UDS), Preparation of Bore-logs.

Laboratory Testing:

On completion of drilling, samples are sent to the soil testing laboratory for further testing. Samples are classified in the geotechnical laboratory and representative samples are selected for testing. Following tests would be performed.

  • Dry Density
  • Soaked unconfined Compression Test
  • Percentage absorption and porosity
  • Mechanical analysis
  • Atterberg limits
  • Differential free swell
  • Proctor Density Test
  • CBR Test
  • Direct Shear Test
  • Triaxle Tests

After getting the laboratory soil test report & bore-logs, the recommendation report is prepared by geotechnical expert, which would be helpful to decide the type of foundation on the basis of safe bearing capacity.
