Travaux de carrière - District Nord

Quarrying works in the north of England (Northumberland) comprise extraction and processing of aggregate from 4 (maybe 5) hard rock quarries, including associated drilling and blasting works. Materials are extracted in relatively small quantities and used in various Forestry England civil engineering applications, mostly for the construction and maintenance of forest roads for the purposes of facilitating timber harvesting. Quarrying operations are therefore undertaken in a number of specific locations, in close proximity to the point of use of the extracted materials. Typically, extraction of materials will take place over a period of a few weeks each year, with material then stockpiled within the quarry, or at other designated locations for use as and when needed. This Framework will be divided in to two Lots: 1. Drilling and blasting 2 . Extraction and quarry development and crushing Lot 1 - Drilling and blasting The Supplier carries out all drilling and blasting operations, in accordance with the Quarries Regulations 1999 particularly Part V and the Explosives Regulations 2014 , and the quarry Health and Safety Document. Blasting activities typically take place at 2 to 5 sites per year, with tonnages between 20,000 and 35,000T per blast.
