Land, DGPS & drone surveying
Service detailsWhat is the difference between a DGPS survey and a total station survey?
DGPS uses satellite signals to fix positions over large areas and long routes quickly. A total station measures angles and distances from the instrument and is ideal for precise layouts and detailed site work. Most projects use both.
When is a drone survey the right choice?
For large or hard-to-reach areas — rivers, barrages, open land. We fix ground control points with DGPS so the drone data is accurate, then deliver contour maps and drawings.
What do I receive at the end of the survey?
AutoCAD drawings, grid and contour maps, KMZ files for Google Earth and, where needed, quantity reports.
Solar foundation works
Service detailsHow are solar piles marked on site?
Pile points are set out from the approved layout with a total station and DGPS, then pegged and checked for alignment and level before concreting.
Do you work on large solar plants?
Yes — including peg marking for 32,000 solar piles and survey work for a 300 MW SECI solar project in Andhra Pradesh.
Irrigation & shotcrete works
Service detailsWhat is shotcrete canal lining?
Concrete sprayed at high speed onto the canal slope. We apply it in two layers of about 38 mm with weld mesh fixed between them, which strengthens the slope and reduces seepage.
Which canals have you worked on?
The TGP main canal near Allagadda (about 11,000 m²) and the HNSS Punganur Branch Canal near Madanapalle, among others.
Railway surveys
Service detailsHave you surveyed railway projects?
Yes. For APIIC we marked the railway centre line with DGPS and prepared digital land-profile sections and quantities for the Gati Shakti cargo terminal at Kopparthy, completed in about a month.
Transmission lines & substations
Service detailsWhich line surveys have you done?
Surveys for 14 km and 12.8 km 33 kV double-circuit lines and the 295 MW project line in Kurnool district, among others.
Do you also build the foundations?
Yes — HT line foundations and substation-yard foundations for transformers, CT, PT and VCB equipment.
Buildings & boundary walls
Service detailsAre you a registered contractor?
Yes — a Class-V civil contractor registered with the Public Health & Municipal Engineering Department, Government of Andhra Pradesh.
