About CivilTech

CivilTech is a static reference site for engineers and contractors: short topic notes, formulas, and on-page calculators for rough checks and teaching—not a substitute for full project modelling or statutory sign-off.

What we cover

  • Structural — load analysis; steel and reinforced concrete design; dynamics; stability; other and high-performance materials; earthquake and special structures; connections; failure and life-cycle topics; structural fire engineering.
  • Geotechnical — soil classification; bearing capacity; settlement; retaining walls and earth pressure; slope stability; seepage.
  • Hydraulics & hydrology — open-channel and pipe flow; rainfall–runoff; stormwater; basic groundwater.
  • Transportation — traffic; geometric design; pavements; planning; safety and operations.
  • Construction / project — quantities; cost; scheduling; resources; progress; risk and productivity.

Where it matters, pages reference SANS and South African regulatory context. Always verify against the code edition and design basis on your job.
