Taipei deep trench excavation and piling works
Visitation and evaluation of various dealer companies, steel manufacturing factories, harbors and power plants in cooperation with Caterpillar of Taiwan.
On the Taipei site we investigated some problems arising in equipment due to very harsh, wet conditions and a mixed ground structure where various intermingling layers of clay, rock and sand delivered challenges to the equipment in operation.
Deep trench excavation
refers to the process of digging a trench or excavation that is significantly deeper than the average depth of a standard trench. It is often required for various construction, infrastructure, or utility projects where deeper foundations, pipelines, or structures are needed. Here’s some information on deep trench excavation:
- Purpose: Deep trench excavation is typically undertaken to install underground utilities such as sewer lines, water mains, gas pipelines, or electrical cables. It can also be necessary for building foundations, basement construction, or tunneling projects.
- Planning and Design: Deep trench excavations require careful planning and engineering design to ensure safety and stability. Factors such as soil conditions, groundwater levels, adjacent structures, and any existing utilities must be considered. Professional engineers and geotechnical experts analyze the site and develop a detailed excavation plan.
- Safety Measures: Due to the increased depth and potential risks involved, strict safety measures are crucial during deep trench excavation. These may include shoring, bracing, or sheet piling systems to prevent cave-ins, as well as proper sloping or benching techniques. Adequate ventilation, lighting, and access points for workers are also essential.
- Equipment: Specialized heavy equipment is typically used for deep trench excavation. Excavators, backhoes, or trenchers are commonly employed to remove the soil. In some cases, specialized equipment such as clamshell buckets, hydraulic breakers, or rock saws might be necessary depending on the ground conditions.
- Soil Excavation and Support: The soil or rock removed from the trench is usually stockpiled nearby or transported off-site for disposal. In deep trench excavation, the sides of the trench need support to prevent collapses. This can be achieved through various methods like sloping the sides at a safe angle, using protective trench boxes, or installing temporary shoring systems such as soldier piles, sheet piles, or trench sheets.
- Dewatering: Deep trench excavations often encounter groundwater. To work in a dry environment, dewatering techniques may be employed, such as well-point systems, sump pumps, or deep wells. These methods help lower the water table to facilitate construction activities and maintain stability.
- Inspections and Monitoring: Regular inspections and monitoring are conducted during deep trench excavation to ensure the stability of the trench and adherence to safety standards. This includes checking for any signs of ground movement, monitoring groundwater levels, and inspecting the integrity of support systems.
- Backfilling and Compaction: Once the required utilities or structures are installed, the trench is backfilled with suitable materials. Proper compaction methods are applied to ensure stability and prevent settling over time. This is done in layers to achieve the desired density and minimize the risk of future ground movement.
Deep trench excavation requires experienced professionals and adherence to relevant safety regulations. It is essential to consult with engineers, geotechnical experts, and local authorities to ensure compliance with applicable codes and standards for a successful and safe excavation project.
What is piling?
Piling work in construction refers to the process of installing piles, which are long, slender columns typically made of concrete, steel, or timber, into the ground to provide structural support for buildings, bridges, and other types of structures. Piling is commonly used when the soil or ground conditions are weak or unstable, or when the load-bearing capacity of the soil needs to be increased.
Here are some key points about piling work in construction:
- Purpose: Piling work is primarily done to transfer the load of a structure to a deeper, more stable layer of soil or rock beneath the ground. Piles can also be used to resist lateral forces such as wind or water pressure.
- Pile Types: There are various types of piles, including driven piles and bored piles. Driven piles are hammered or vibrated into the ground, while bored piles are created by drilling a hole into the ground and then filling it with concrete or other materials.
- Pile Materials: Piles can be made of different materials depending on the specific requirements of the project. Common materials include concrete, steel, and timber. The choice of material depends on factors such as load-bearing capacity, soil conditions, and environmental considerations.
- Pile Installation: Pile installation involves several steps. First, the site is prepared by clearing the area and, if necessary, excavating the ground. Piles are then positioned and driven or bored into the ground using specialized equipment. Once the piles are installed, they are typically cut to the required level and capped with a pile cap or a pile cap and a pile cap beam.
- Testing and Verification: Piles are often tested to ensure they meet the required load-bearing capacity. Common testing methods include pile driving analysis, dynamic load testing, and static load testing. These tests help verify the integrity and performance of the piles.
- Piling Contractors: Piling work is usually carried out by specialized contractors who have the expertise, equipment, and experience to handle the complexities of pile installation. These contractors work closely with engineers and architects to design and implement the piling system based on the project’s requirements.
Piling work is a crucial aspect of many construction projects, especially when dealing with challenging ground conditions or heavy structural loads. It is essential to engage experienced professionals to ensure the successful installation of piles and the overall stability and safety of the structure being constructed.
The Bauer heavy duty construction machines were designed and consigned for piling works in a construction site in Taipei.

Taipei 101 is an iconic skyscraper located in Taipei, Taiwan. It is one of the most recognizable landmarks in the city and has become a symbol of Taiwan’s economic success and modernity. Here are some key features and information about Taipei 101:
- Height and Architecture: Taipei 101 stands at a height of 508 meters (1,667 feet) and held the title of the world’s tallest building from 2004 to 2010 until it was surpassed by the Burj Khalifa in Dubai. The building has 101 floors above ground, and its design combines elements of traditional Asian culture with modern architecture.
- Sustainable Design: Taipei 101 is known for its sustainable design and has been awarded LEED Platinum certification, which recognizes its environmentally friendly features. The building incorporates features such as double-pane, low-emissivity glass to reduce heat and energy consumption, rainwater recycling systems, and efficient air conditioning and lighting systems.
- Damper System: One of the notable engineering features of Taipei 101 is its tuned mass damper (TMD) system. Located near the top of the building, the TMD is a massive steel pendulum that helps to stabilize the tower and reduce the impact of strong winds and earthquakes.
- Shopping and Dining: Taipei 101 houses a vast shopping mall with a wide range of international luxury brands, designer boutiques, and local retailers. The mall also offers a variety of dining options, including restaurants serving Taiwanese cuisine and international flavors.
- Observatories: Taipei 101 has two observation decks located on the 88th and 89th floors. These decks provide visitors with stunning panoramic views of Taipei City and its surroundings. The outdoor observatory on the 91st floor offers an even higher vantage point, allowing visitors to enjoy the fresh air while taking in the scenery.
- New Year’s Fireworks Display: Taipei 101 is famous for its annual New Year’s Eve fireworks display, which attracts thousands of spectators. The synchronized fireworks show is a highly anticipated event and has gained international recognition for its grandeur and creativity.
- Transportation: Taipei 101 is well-connected to the city’s transportation system. It has its own MRT (Mass Rapid Transit) station, Taipei 101/World Trade Center Station, which is part of the Xinyi Line. The building is also easily accessible by bus and taxi.
