A unified approach to the construction of weighing matrices and certain symmetric designs is presented. Assuming the weight p in a weighing matrix W(n,p) is a prime power, it is shown that there is a W(\fracpm+1-1p-1(n-1)+1,pm+1) for each positive integer m. The case of n=p+1 reduces to the balanced weighing matrices with classical parameters W(\fracpm+2-1p-1,pm+1). The equivalence with certain classes of association schemes is discussed in details.
