At A Glance

  • Client needed to monitor construction at a remote site with extreme temperatures
  • Drone based construction analytics provided as-built updates referenced to design
  • Significant savings on manpower, logistics with improved transparency, reporting

 

Problem

One of the leading solar power developers in India was having difficulty in monitoring the construction progress of a 450MW plant in north western India.  The area was known for extreme weather with average temperatures between 46 and 48 degrees celsius accompanied by hot winds and sandstorms. The nearest habitation was a village 50 km away. The client faced challenges in managing construction due to factors such as:

  • Low accessibility and infrastructure on-site
  • Extreme weather reducing field personnel effectiveness
  • Coordination issues with usage of excel/WhatsApp for project tracking 

The client wanted a solution that would reduce the manpower involved in monitoring construction. 

Solution

The client reached out to SenseHawk in early 2019 for a cost-effective, digital method of project progress monitoring. The client wanted regular status updates on civil, mechanical, electrical installation progress in a seamless manner.  Sensehawk team deployed the Sensehawk Eye product which uses drones to help clients monitor the progress of solar plant construction and manage construction better. The client’s senior management COO and VP Projects took a hands-on approach to deploy the technology solution and the Sensehawk team guided the client on deploying their own drone for data collection using RGB cameras for visual imagery. The client’s proposed plant was set up in the SenseHawk system with the digital layout mirrored from CAD and site plan files.

Once the drone imagery was uploaded into Sensehawk Eye, the system analysed the images, constructed a map of the plant and flagged all the components marked in the ‘as-designed’ layout and colour-coded the site for construction progress with green indicating completed, amber indicating in progress and red indicating yet-to-start. The client conducted 11 scans with an RGB camera (each drone scan consisted of around 7-8 flights over the site. Each flight would last around 25 minutes). In the initial phases, a scan was scheduled fortnightly, towards the end of the project, the scans were executed on a monthly basis. 

 

Benefits

The client conducted weekly drone scans to assess the state of construction progress and with Sensehawk platform providing flags for every construction component such as modules, rafters, piles, inverters, combiner boxes etc, it was easy for the senior management to track construction progress and track milestones with the contractors. Generating MIS reports also became easier without need for an MIS team. The project team was also able to flag issues on site by creating tickets attached to specific sections of the plant under construction, so the field team could proceed to the exact location of the ticket using the SenseHawk Mobile App and resolve the specific ticket. Key benefits were:

 

  • Improve transparency and single-source data across design/ contractor/ project managers and site teams
  • Reduce costs of logistics/ manpower on-site / MIS teams for tracking
  • Improve productivity by digitalising site operations
  • Ensure on-time execution of the project
