Overview
Designs based on a deed sketch or a tape measurement often go wrong. A boundary is a metre off, the road is narrower than assumed, or the plot falls a level toward the back. A digital survey fixes these facts before the plan is drawn, rather than after the foundation is dug.
Every design and approval drawing starts from the plot. A digital land survey measures the land as it actually is, including its boundaries, area, road widths, levels, existing structures, and trees. It then produces a CAD drawing that the architect, the structural engineer, and the approving authority can all work from. In Bangladesh, it is also how the physical plot is compared with the mouza map and the deed.
When you need it
- Before architectural planning on a new plot.
- A survey-based site plan is needed for a building plan application.
- You want to confirm the area and boundaries of land before buying it, or while a dispute is being settled.
- The site has level differences, or flood levels matter for the plinth height.
- Columns and grid lines need to be set out accurately on site before construction.
What's included
- 01
Boundary and area survey
Plot corners, boundary lines, and area measured and calculated from the field data.
- 02
Topographic survey
Spot levels and contours, drainage, roads, and existing features across the site.
- 03
Mouza map comparison
The surveyed plot compared with the CS, SA, RS, or city survey mouza map and dag boundaries.
- 04
Road and setback measurement
Abutting road widths and distances measured for setback and access calculations.
- 05
Setting out
Grid lines and column positions marked on site from the approved drawings.
How it works
- 01
Collect documents
The deed, mouza map, and dag and khatian details are collected for the plot.
- 02
Field survey
The plot is surveyed with a total station or GNSS equipment.
- 03
Drafting and comparison
The survey is drafted in CAD and compared with the land records.
- 04
Handover
Drawings and the area statement are issued, and any discrepancies are explained.
What you receive
- CAD survey drawing
- Survey plan in DWG and PDF formats, ready for design use.
- Area statement
- Measured plot area, with a comparison against the area stated in the deed.
- Level and contour plan
- Ground levels and contours for plinth, drainage, and earthwork decisions.
- Setting-out record
- Coordinates and reference points used to set out the building on site.
Codes & inputs
- Land recordsDeed, khatian, dag numbers, and mouza map for the plot.
A survey measures and records the land. It does not settle legal ownership, which is determined by land records and, where necessary, by the relevant land authority or court.
Questions about land survey
What if my plot does not match the mouza map or the deed?
Differences between the deed area, the mouza map, and the land on the ground are common. The survey records what is actually there and shows the differences clearly on the drawing. Resolving ownership or boundary disputes is a legal matter for the land authorities, but an accurate survey gives you reliable facts to take to them.
Why use a digital survey instead of a chain or tape survey?
Total-station and GNSS equipment measure angles, distances, and levels precisely and record them digitally, so the survey can be drawn directly in CAD without manual transcription. The result is more accurate, includes levels, and can be used immediately by the architect and the structural engineer.
