Diameter-inch and progress measurement — the unit piping is paid in
What a diameter-inch is and how it is counted, why it under-represents small bore, the difference between claimed and earned progress, the measurement rule that has to be agreed before work starts, and why the last ten per cent of a piping package takes months.
Construction productivity factors — why the same weld takes three times as long
Why a norm measured in the shop does not survive contact with a live unit, the conditions that multiply the hours without changing the work, crew composition and what a waiting welder costs, and the difference between a crew that is busy and a crew that is producing.
