Challenges Faced in High-Rise Constructions

A high-rise structure has a compact footprint, a tiny roof area, and a massive facade. High-rise structures have the ability to decongest urban sprawl as they can deal with high-density difficulties and a shortage of sufficient space for development.

The construction of a high-rise skyscraper is a lengthy procedure., and it necessitates careful consideration of a number of elements. This article discusses some of the issues in architectural, structural, and MEP design, investigations, construction, and maintenance.

Many structural design courses on high rise buildings state the following challenges faced while construction of the skyscrapers. 

Because high-rise structures are supposed to be lightweight, choosing materials for structural and non-structural parts can be difficult during planning and construction. High-performance concrete (HPC), pre-stressed concrete, composite construction with steel, high-strength ASTM A36 steel which is perfect for constructing buildings, lightweight masonry for walls and partitions, and other materials are becoming increasingly important.

  • Wind & Earthquake resistant design

Wind and earthquake forces are the most common loads that necessitate lateral structural design. Furthermore, in the event of high deflections and vibrations, inhabitants may experience nausea; hence, buildings must be constructed for both earthquake protection and comfort. 

In the case of high-rise structures, wind loads are usually the deciding element in structural design. Because the design of a building is so important in reducing wind pressures, circular, chamfered corners square, or nearly circular and square-shaped structures are recommended.

  • Geotechnical Investigations

High-rise structure foundations require special consideration during both geotechnical research and construction. The main premise of geotechnical research is to dig as far as the building’s height into the ground. 

  • Provision of Basements

Because of the increased demand for parking services in high-rise buildings, basements are almost a must. For designers and engineers, all of the tasks related to basement building, such as retaining walls, diaphragm walls, and subsurface waterproofing, represent a problem.

  • Efficient Vertical Transportation System

In high-rise structures, vertical transportation systems must be exceedingly efficient and quick. It is better to employ contemporary technology or super-light rope technology with a carbon-fibre core and a high friction coating.

  • Construction and Fire Safety

Structural safety, worker safety during construction and maintenance, safety from falling components, and fire safety are all important aspects of high-rise building safety. Because fires in high-rise structures may cause significant damage, safety is a primary issue for high-rise construction. 

  • Speed of Construction

Another issue is the rapidity with which high-rise structures are constructed. For speed, new building technologies are constantly implemented in high-rise projects, ensuring quality, safety, and economic stability. Concrete pumping, lifting materials and equipment, and working at higher heights in towering structures are just a few of the key problems.

  • Repair and Maintenance

The repair and maintenance of high-rise buildings and services is another issue. In such buildings, the costs of maintenance and repair are also high. Providing accessible access for service maintenance is also a challenge for architects and engineers. These are a few challenges faced by civil engineers while constructing high-rise buildings.
