increased optimism in the property industry, which should lead to an increase in enquiries and an upturn in construction business confidence. Chapman adds:“ It has been a difficult time during the slowdown, but it is positive to hear that there has been a pickup in the market. There are a lot of players in our industry and the pricing is becoming increasingly aggressive,” he notes. This price war has led to a different approach when awarding tenders, Du Plessis says:“ Where before we would have put numerous contractors on tender lists for say, the bulk earthworks, we have substantially reduced the number of companies invited to tender to ensure only companies with the required skills, integrity, and financial backing are considered, with the goal not to jeopardise quality over cost.” As the two metropoles of Johannesburg and Pretoria edge slowly towards each other, developments such as the new Deloitte HQ will ensure that the merge is smooth and hopefully, not too big a culture shock to either city.
“ We had to be sensitive to the environmental impact of the construction on the wetland area and so too, to our LEED rating.”
