DIWI has contributed to the development of the Botswana road network extensively since 1993 when we undertook the design review and construction supervision of a 217km section of the Trans-Kalahari Road corridor. Since then, we have provided similar services on an additional 255km of essential trunk roads. Our in-depth knowledge of conditions and materials in the country has greatly contributed to the successful completion of several projects with a construction value of approximately US$136 Million. We continue to apply our wealth of experience to ongoing projects in the country.
