BUSINESS conditions in the building remain tough for at least the next six months, the Bureau for Economic Research at Stellenbosch said on Tuesday. The BER, attached to Stellenbosch University, said it anticipates that the overall construction cycle will reach a low in the last quarter of the year before general conditions improve. The survey, done during the first quarter of 1999 shows that work done by respondents declined further and the lack of new work made tenders more competitive.
