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 .”
