You’ve probably heard about a space ship hitting badly Venus or Mars, I don’t remember, because of miscalculations, right? Well, that’s everywhere. When you do your taxes, when you calculate your retirement or when you receive an inheritance. All are miscalculation errors. In construction, there are everywhere. In 1970, during the construction of the Kadena Air Base Bridge in Okinawa, Japan, engineers made a slight miscalculation. As usual… Two teams started building from opposite sides of the river, expecting to meet perfectly in the middle. But when they finally got close... one side was 2 meters higher than the other! I mean… not 1 cm, not 2 cm, not 10 cm… just 2 meters. The error? One team had used metric measurements, while the other worked in imperial units. If you think that this is impossible today, you’re absolutely wrong. If you don’t believe me, check this list of lessons learnt from my last project.

Some of the worst PPPs in the world come from capital cities trying to look impressive. Huge buildings. Architectural statements. Politicians cutting ribbons. And budgets exploding. But some of the best PPPs? They come from places nobody talks about. Take Ferguson Place Recreation Centre PPP. It sits in Fort St. John, Canada… Oh Canada! Population: about 21,000 people. Not exactly Tokyo. The city needed something simple: A recreation centre. Swimming pools. Ice rinks. Fitness facilities....
A toll road. In one of the richest regions of Europe. Northern Italy. Lombardy. Industrial powerhouse. Traffic everywhere. What could possibly go wrong? The project was called the Autostrada Pedemontana Lombarda. A massive motorway designed to connect cities north of Milan and relieve congestion around the region. On paper, it looked like a dream. Economic powerhouse region. Millions of inhabitants. Constant truck traffic. Banks were queuing to through their money to the asphalt plant. Making...
The system worked perfectly. The satellites tracked the trucks. The software calculated the tolls. The invoices were ready. The gantries were already installed across France. 173 of them. Steel structures over highways, quietly waiting for trucks to pass and pay. The project cost almost €1 billion. It was called the Écotaxe Poids Lourds. The idea was simple. Heavy trucks should pay for using the roads. Especially foreign trucks crossing France. Elegant. Who would say no to such a great idea?...
