While procuring diamonds for its stock, Al-Sarraj's qualified diamond experts always look for excellence in cut, clarity, colour, fluorescence, proportions and finish grades
These elevations are obtained by subtracting the required topsoil layer, pavement and pavement base, or other nonsoil subgrade improvements from finish grade
. Subgrade establishment does not require the precision of finish grading, but should be as accurate as possible to reduce grading work later in the project.
Caterpillar has introduced the D6K track-type tractor, which is the first in a new line of crawler dozers designed to deliver best-in-class productivity and performance from first cut to finish grade
. The D6K comes standard with a new hydrostatic drive train, durable SystemOne[TM] undercarriage, and seat-mounted electro-hydraulic controls ready for easy installation of the AccuGrade[R] grade control system.
Additional smoothing and shaping of the finish grade
may be undertaken before establishing turf areas.
