The South African National Roads Agency Limited (Sanral) has awarded four major construction tenders collectively worth nearly R7-billion for projects in KwaZulu-Natal and the Eastern Cape, which will help boost the construction sector and should be seen as part of the broader national effort by government to invest in economic infrastructure, it said. Additionally, in line with its commitment to the economic development of black businesses, at least 30% of the contract value of each tender will be subcontracted to small, medium-sized and microenterprises (SMMEs).
