As many as 20 units of Komatsu PC210-8M0 Hydraulic Excavators worked arduously in this inhospitable terrain making it happen. Some of these machines, fitted with Rammer Rock Breakers, were used for breaking and excavating blasted hard rock, often disrupted by snowfall, landslides and flash floods. Komatsu PC210 machines played a critical role in the construction despite engaged for only six-seven months in a year owing to snowy conditions for the balance period. The project was executed by Garg & Garg, based in Ropar-Punjab, and was engaged by BRO to complete a major portion of this road construction project. L&T supplied the Komatsu machines and provided the service support to the customer at site.
