Inspecting materials on site — delivery day

Page code P25 · 36 inspection criteria · 3 illustrations

Every stage in this book inspects workmanship, except this one page, which inspects materials. Steel of the wrong grade, cement that has sat in a warehouse too long, pipes that don't meet the standard — these three things make every other criterion in the book meaningless, because no amount of good workmanship can make up for the wrong materials…

This page contains
Delivery day — a hold point nobody schedules for you
Standard marks — shape, position and the point people most often misunderstand
Rebar — four things embossed on the steel
Bagged cement — five things on the bag, and the fourth one people overlook
Table of TIS numbers for materials used in houses — and the cells that can't be filled in yet
Six things you can check by eye without knowing any standard numbers
