The Sea Wall That Saved a Nation | Summary and Q&A

TL;DR

The Osijl Dike, an engineering marvel constructed over 85 years ago, is being reinforced to withstand rising sea levels and stronger storms.

Key Insights

• 🥳 The Osijl Dike was constructed over 85 years ago and has been credited with saving large parts of the Netherlands from flooding.
• 🤢 Rising sea levels and stronger storms necessitate a major reinforcement project for the dike.
• 😒 The reinforcement involves the use of concrete blocks, new drainage systems, and the implementation of advanced technology.
• 📽️ The project involves the collaboration of over 500 professionals, including architects, civil engineers, and contractors.
• 😒 The use of technology, such as Autodesk's BIM 360 and assemble software, has greatly improved design coordination and efficiency.
• 🛄 The upgrade aims to protect the Netherlands from flooding until at least 2050.
• 👷 The dike's construction in the 1920s did not consider the impact on local habitats, but the upgrade includes measures to encourage biodiversity and restore fish populations.

Questions & Answers

Q: Why is the Osijl Dike being reinforced?

The dike is being reinforced due to rising sea levels and stronger storms, which pose a threat to its ability to protect low-lying areas from flooding. A 1 in 10,000 year storm is being prepared for.

Q: How was the Osijl Dike originally constructed?

The construction of the Osijl Dike was a massive undertaking that required more than 36 million cubic meters of material. Ships dredged material and deposited it onto the seafloor until it breached the surface, and rocks were used to strengthen the dike.

Q: What is being done to reinforce the dike?

Rather than raising the height of the dike, engineers are adding a layer of concrete reinforcing blocks along its length. Microchips will be embedded in each block for future maintenance. New pumping stations, expanded locks, and a widened causeway are also being constructed.

Q: How has technology aided in the upgrade of the dike?

The project team is utilizing Autodesk's BIM 360 model coordination platform to coordinate and detect clashes in design models before construction. Autodesk's assemble software is also used to track and manage changes between models, improving efficiency.

Summary & Key Takeaways

• The Osijl Dike, built 85 years ago to protect the Netherlands from flooding, spans 32 kilometers and holds back the Wadden Sea.

• Due to rising sea levels and stronger storms, the dike is undergoing a $617 million upgrade to withstand a 1 in 10,000 year storm.

• The upgrade includes adding concrete blocks for reinforcement, constructing new drainage systems, and utilizing advanced technology.
