What a knock through with steel quote should include

  • Engineer's calculations (who arranges and pays)
  • Temporary support
  • Steel size per design
  • Building control sign-off
  • Making good and what finish is left

Common mistakes

Pricing without the calcs

Steel size drives the price. Quote subject to the engineer's design.

Making good left vague

Say whether you leave it ready for decorating or not.

Does it need building control?
