J.R.

This project presented many challenges, the largest of which was the sheer quantity of material that required exporting through a residential neighborhood. J.R. Vinagro designed a project plan that involved large amounts of blasting, which produced 200,000 CY of regulated soil export and 600,000 CY of rock export. The plan also included more than 36,000 linear feet of utility installation. The project scope, combined with the site location in a residential area, posed a considerable challenge for both phases of site preparation.


J.R. Vinagro set up the project with enough staff to manage export trucking as though it was its own quarry operation, so that a loaded truck left the site on average every 1.4 minutes. Our teams were equipped with a large fleet of heavy machinery including a Cat 6015B, Komatsu PC 1100, Cat 988K, (3) 374s, 10 rock drills, 150 on-highway trailer dumps, and 30+ pieces of other equipment including off-road trucks, hammers, excavators, loaders, crushers, dozers.
