Site Development | Rock Excavation
Ryangolf’s expertise with rock excavation and handling is superior compared to the standards set by many of the smaller, less experienced firms. In order to be productive in this important phase of construction, hard rock handling requires a different set of operational and managerial skills, equipment fleet and resources to perform this work. Ryangolf offers the experience necessary to transform a challenging site into a finished product built to accepted industry standards.
In many instances, earthwork projects will need substantial site cuts or pond excavations to generate the fill required to achieve the proposed elevations. When rock is present, sometimes as deep as 50 feet below existing grade, rock excavation is required; a task that Ryangolf has performed for many Clients.
The removal process typically begins with blasting operations. The certified blaster drills several holes into the rock layer with a large drill rig, loading these holes with explosives. The explosives are detonated via remote controls allowing the energy generated by the blast to fracture the rock within the surrounding area. This operation facilitates the rock removal professionally and without damage to adjacent structures.
The fragmented rock is removed with excavators and trucks to be used in deep fills buried on-site or used for further processing. If crushed rock is desired, a large crusher is used to grind the rock into smaller material for use in fills and/or the construction of the roadway in the base course.
At times, it may be more economical for the developer if the rock is buried in a hole on-site. In this case, a borrow pit is dug through the sand layer to the rock layer. The excavation is then backfilled with the previously excavated rock and covered with a layer of sand. This procedure generates valuable sand that can be recycled on-site for a variety of uses, including building pad construction and golf course construction.
