Book Three of the Waterwheel series — construction and engineering, written by a teacher with over 30 years with working professionals.
English for construction and engineering
The village is building its first waterwheel mill, and you are on the job. Nadia wants to know why the levels differ by 180 millimetres. Peter has forty cubic metres of concrete booked and rain coming. You'll be on site, in English, in about ninety seconds.
Setup takes two minutes. No questionnaire, no placement test.

No chapters. No exercises. You walk onto a site where the levels don't agree, an excavator is standing idle, and everyone is waiting for your answer.
The same late delivery of oak asks a site manager, a quantity surveyor and a design engineer three completely different questions.
Mr. McArthur never interrupts the meeting. Call him when you're stuck, and afterwards he tells you the three things worth fixing.
“I wasn't doing an English exercise. I was doing my job, in English.”
