Sidian
our story
Built to close the gap between advising and executing
Sidian is a specialist construction capability consultancy that partners with engineering organisations to design, build and lead world-class project delivery teams, helping EPCM houses evolve into fully capable EPC execution businesses by embedding the people, systems and controls required for safe, compliant and efficient project execution.
Sidian was founded to solve a critical gap in the construction industry: organisations have projects, but not the capability to execute them. After 14 years building construction teams, systems and controls inside major contractors and mining houses, founder Andreas Kolbe, PMP, established Sidian to deliver that capability as a specialised consulting service.
His track record spans high-risk, high-value industrial and mining projects across South Africa, Namibia and the DRC, including the R1.8bn Time Square Casino, the R840m Husab Uranium plant, the R642m Medupi SMPP and Anglo Platinum’s charge floor rehabilitation. As operations director he has delivered more than 200 projects, with teams of over 220 personnel under his management.
Today Sidian brings that experience to its clients directly: the people, processes and project leadership required for safe, compliant, high-performance execution.
People choose Sidian because we deliver high-risk industrial and mining projects with discipline, clarity and control. We don’t just advise. We build. Sidian embeds the teams, systems and project controls that let organisations execute for themselves.
