After this course

What you'll be able to do yourself.

Wrongly placed steel disappears for good once the concrete is poured. This course teaches how to read reinforcement schedules, why each bar sits where it does, and what to check before a pour. Bar sizes and counts stay with the engineer. You learn to read and inspect them.

  1. 1Read bar notation, grades and spacing on structural drawings.
  2. 2Explain what concrete cover does and its common values.
  3. 3Read beam, column and joint reinforcement from schedules and details.
  4. 4Inspect reinforcement before a pour and record findings properly.
  5. 5Redraw reinforcement details from the engineer's data.

Good for

  • Drafters who draw or check concrete details.
  • Junior architects who are often on site.
  • New site inspectors who have to sign pour approvals.

Slide the value. The drawing follows, just like in the lessons.

Closer near the column, where shear peaks. The final value still comes from the structural engineer.

  • Rizal Maulana

    Site supervisor

    The reinforcement chapter is very clear. I can now read rebar drawings on site.

  • Yohana Simanjuntak

    Junior engineer

    Slide the Parameter makes stirrup spacing feel real. In a book it's just a number.

  • Fikri Hidayat

    Drafter, 2 years in a studio

    As an architect I can now talk to the engineer without just nodding along.
