5 things you can learn in the Build It zone?

1. The Lagan Weir in Belfast

Found in the heart of Belfast is The Lagan Weir. A total of 5 weirs can be found here with gatehouses between them. There is even a tunnel running under the River Lagan so engineers can get to the gatehouses. The weir keeps water levels in the city centre stable and protects against tidal surges. It even aerates the river which raises oxygen levels and makes the water a better home for wildlife!

2. How do buildings stay standing?

There are an array of different forces that work together to ensure a building remains standing. The weight of the roof pushes down while the foundations work against this, pushing back up with an equal and opposite force. Foundations need to be very stable. If not, the building can collapse.

3. The Leaning Tower of Pisa

Did you know the Leaning Tower is the bell tower of Pisa's cathedral? Soon after it was built, the foundations shifted in the soft ground, causing its leaning appearance. Despite the building's alarming angle, it's still standing more than 600 years later.

4. The strength of an arch

Despite an arch's delicate appearance, it is structurally strong and rigid. Curves are stronger than straight lines as any weight above an arch is spread evenly around the curves so there's no single point taking the strain.

Designed by a Danish Architect called Jorn Utzon, the modern expressionist design comprises of unique shell structures made of concrete but still manages to look light and delicate. The building covers 4.4 acres of land and is supported by 588 concrete underground piers.
