The accompanying drawing shows ground contours at five-metre vertical intervals. AB is the line of a proposed roadway and CDEF a proposed parking area. The roadway AB has the following specification:-

(i) formation width from A to B is 15 m, from C to F the road is widened as shown to form the parking area CDEF;
(ii) formation level at A is 35 m;
(iii) gradient A to B is 1 in 15 falling;
(iv) side slopes for cuttings 1 in 1.5;
(v) side slopes for embankments 1 in 2.

In the parking area CDEF the sides CD and FE are level and the gradient from C to F is 1 in 15 falling.
The side slopes for cuttings and embankments are the same as for the roadway.

On the drawing supplied show the earthworks necessary to accommodate the roadway and parking area.
