A Group Divisible design (v, b, r, k, , ; m, n) is said to be Semi-Regular when r- > 0 and rk – v = 0. In this paper it is proposed that starting from Semi-Regular Group Divisible (SRGD) design with k = m, = 0, many series of Group Divisible (GD) designs are constructed without disturbing its Semi-Regular property. Such design are useful in the formation of different plats of same size reinforced Cement concrete, by having choice of different iron bars of different gauges by civil engineers.
