Our Design Engineering vertical undertakes designing and testing of a wide range of transmission & distribution lattice and monopole structures. We have a well-equipped design facility and a talented team of experienced design engineers and detailers in Mumbai, Nagpur, and Vadodara.
Our design engineers carry out the following activities for the in-house projects and external customers.

Transmission Lines

  • Surveying using latest technologies (GPS, DGPS and total stations)
  • Routing using GPS technology, satellite maps and online application
  • Tower spotting using latest technologies to determine route profile and optimal distribution of transmission towers on route profile
  • Review of geotechnical soil investigation
  • Civil – Design of optimum foundation design
  • Design of self-support structures or guyed structures
  • Electrical – Grounding, clearance, and sag analysis

Lighting Solutions

  • Review of geotechnical soil investigation
  • Civil – Design of optimum foundation design
  • Design of high mast or pole structures
  • Lighting design and optimum lux output to cater to requirements


  • Electrical Engineering: Single line diagram, general layout and relevant sections, control and protection (SCADA), cables calculation, equipment analysis and selection
  • Mechanical Engineering: Gantries and support design structures
  • Civil Engineering: Equipment foundations and cable trenches and building

The Design Facility uses the latest software like PLS CADD, PLS Pole, PLS Tower, STAAD Pro, Auto CAD, BOCAD and i-Tower to design lattice towers and monopoles. PLS-CADD is used for tower spotting, while Method-4 is used to optimise quantity estimation. The design drawing data are automatically transferred to CNC machines at the factory.

Our design team has the competency to design towers compliant to all international standards. Some of their latest achievements include successfully designing extra high river crossing towers as well as towers up to 1200 kV. The core expertise lies in conducting voltage upgrade studies through structural analysis of towers/poles in existing lines as well as strengthening for higher voltages and re-conducting.

We have successfully designed and tested towers for all geographic and climatic conditions ranging from deserts, hilly terrains, river crossings, valleys, swamps, snow, forests, urban lands, and villages.
