It's been my privilege to have known the construction industry's senior statesman, WBHO chairman Mike Wylie, for many years. During this time I've seen him quietly contributing to those less privileged, including a watershed donation that helped St Joseph's HIV clinic near Bronkhorstspruit save many lives. In this interview Wylie explains why he answered UMSO Construction CEO Tollo Nkosi's challenge to get involved in the Nelson Mandela CEO SleepOut, who he is bringing along on 11 July and why he has challenged the CEOs of Raubex and Stefanutti Stocks to join in at Liliesleaf.
