Case Studies and Examples 

Quality control is important for architecture which makes sure that the buildings are safe, durable, and meet the intended design standards. In architecture, quality control practices are essential to identify and rectify potential issues during the design, construction, and maintenance phases. This ultimately ensures the safety, durability, and functionality of built structures. Here are a few examples that illustrate the importance of quality control in architecture. 

1. Fallingwater by Frank Lloyd Wright

Frank Lloyd Wright created "Fallingwater '' as a masterpiece of organic architecture. It was completed in 1939 and is known for its surrounding area covered with nature, particularly the waterfall over which it is built. The initial construction was impeded by inadequate waterproofing and structural support. But afterwards, the cantilevered balconies started sagging, and water penetration became a major problem. To preserve it for long-time, the structure was stabilised, its construction improved and corrected, and also the waterproofing issues were addressed in the 1990s.

2. Millennium Bridge in London 

The Millennium Bridge is a pedestrian suspension bridge which spans the River Thames in London. It was designed to be an architectural masterpiece. However, when it opened in 2000, it experienced unexpected lateral movement under pedestrian roads, leading to its closure shortly after inauguration. The issue was attributed to the bridge's natural frequency coinciding with the footsteps of pedestrians, causing excessive swaying. Subsequent modifications, including installing dampers, helped mitigate the problem, highlighting the importance of comprehensive quality control and testing in structural design.

3. The Leaning Tower of Pisa

The Leaning Tower of Pisa is a historic bell tower in Italy that is well-known for its unexpected tilt. Construction began in the 12th century on unstable ground, resulting in the tower's progressive learning. Despite numerous attempts throughout the years to remedy the lean, but the tower continues to tilt. Extensive restoration operations in the late twentieth and early twenty-first centuries stabilised the building, ensuring its status as a UNESCO World Heritage Site.

4. Taipei 101 in Taiwan
