Precision Land Surveying in Chennai
Resolve boundary disputes, match your physical plot with the FMB sketch, and get accurate topographic data for architectural planning. Whether you're buying a plot in OMR or building an apartment in Anna Nagar, our licensed surveyors use advanced DGPS and Total Station technology to secure your legal boundaries.
When do you absolutely need a Land Survey?
You need a professional survey when: 1) Buying a new plot to ensure the physical dimensions match the sale deed. 2) Before architectural planning to provide exact coordinates and diagonals. 3) To resolve encroachment disputes with neighbors. 4) For CMDA or DTCP plan approval submissions.
Our Survey Methodology
- 1. FMB & Document ReviewWe cross-verify your sale deed, patta, and government FMB (Field Measurement Book) sketch to establish the legal boundaries of your property.
- 2. Equipment Setup (DGPS/Total Station)Depending on the plot size and urban density, we deploy millimeter-accurate Total Station equipment or DGPS rovers to establish ground control points.
- 3. Boundary & Topo MeasurementOur licensed surveyors physically mark the corner points, measure diagonals, and capture elevation data if a topographic survey is requested.
- 4. FMB SuperimpositionWe digitally overlay the physical measurements onto the government FMB sketch to identify encroachments or dimensional mismatches.
- 5. CAD Delivery & MarkingYou receive precise AutoCAD (.dwg) and PDF drawings. We can also permanently fix boundary stones on-site.

Common Mistake: Skipping Construction Layout Marking
Many property owners get a boundary survey but let their local mason mark the column centerlines using threads and tapes. This often results in skewed columns, forcing the architect to alter room dimensions. We provide Total Station Layout Marking to digitally transfer your architect's AutoCAD centerline drawing directly onto the physical site before earthwork excavation begins.
Frequently Asked Questions
Why can’t I just use a measuring tape instead of a surveyor?
Measuring tapes stretch and cannot accurately measure angles or diagonals on irregularly shaped plots. This leads to incorrect area calculations, risking FSI (Floor Space Index) violations and CMDA approval rejection.
What is an FMB Sketch and why is it important in Chennai?
The Field Measurement Book (FMB) sketch is a government record maintained by the Tahsildar office. We superimpose your physical plot dimensions over the FMB sketch to prove legal ownership dimensions before you build or buy.
Do I need a land survey before buying a plot?
Absolutely. A pre-purchase boundary survey ensures you aren’t buying encroached land or a plot that is physically smaller than what is stated in the sale deed.
What is the difference between Total Station and DGPS?
Total Station uses a laser to measure distances from a single point, ideal for smaller residential plots in dense Chennai areas. DGPS uses satellite signals for massive tracts of land or agricultural plots where line-of-sight is impossible.
