The Role of a Surveyor in Skyscraper Construction

Definition of a Surveyor

A surveyor or (land surveyor) can be defined as a professional who determines positions on or near the Earth’s surface.

Surveying can be defined as a profession, technique, art and science of defining the terrestrial or three-dimensional positions of points as well as the distances and angles between them. A professional who deals on land surveying is known as a land surveyor. These points are commonly on the surface of the Earth, and these points are usually used to create maps and boundaries for ownership, locations, such as building corners or the surface location of subsurface features, as well as other purposes which are required by government or civil law, such as property sales.

Surveyors generally work with elements of geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, as well as the law. Surveyors make use of the following equipments while surveying.

  • robotic total stations
  • theodolites
  • GNSS receivers
  • Retroreflectors
  • 3D scanners
  • Radios
  • Clinometer
  • handheld tablets
  • digital levels
  • subsurface locators
  • drones
  • GIS, and surveying software.

Definition of a Skyscraper

A skyscraper is a continually habitable high-rise building taking over 40 floors and usually taller than about 150 m (492 ft). A skyscraper is also under a first class survey construction. The skyscraper construction is best on a raft foundation Historically, the term initially referred to buildings with 10 to 20 floors in the 1880s. This definition moved with advancing construction technology during the 20th century. A Skyscraper might host residential spaces, retail spaces and offices. The term supertall skyscrapers can be used for buildings above a height of 300 m (984 ft), while skyscrapers which reach beyond 600 m (1,969 ft) are can be called megatall skyscrapers.

One feature of skyscrapers which is common is that it should have a steel framework that supports curtain walls. These curtain walls bear on the framework below or suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers possesses a steel frame which makes the construction of load-bearing walls taller than of those which are made of reinforced concrete.

What are the Duties of a Surveyor in skyscraper construction

Let’s look carefully at the duties a surveyor in skyscraper construction

  1. The first duty of the surveyors is that he/she have to measure the distance and the angles between specific points on the earth surface.
  2. Prior to the reference points, some important features points are located by traveling.
  3. Detailed research is usually carried out on records associated to the land, survey, and the titles of the land.
  4. The boundary lines should be located by searching for the previous boundary present in the site.
  5. The surveying should be conducted and the obtained results must be recorded. The results are later verified for accuracy and corrections.
  6. Centered on the surveyed records plots, maps, the respective reports of the surveyed site should be prepared.
  7. The findings gotten from the surveying should be presented to the clients and the government agencies respectively.
  8. The official land needs and water boundaries should be established. These land needs and water boundaries are established either for lease or deeds.

Work Characteristics of Surveyor in Building a Skyscraper

The works performed by the surveyor in the construction of a skyscraper can be divided into three different parts. They include:

  1. Field Work
  2. Office Work
  3. Instruments Care and Adjustments

Steps in Building a Skyscraper

The steps involved in the construction of a skyscraper is highlighted below.

  1. Locate a clear piece of land with stable ground and a good location.
  2. Dig a hole to bedrock level to support the building; this can be up to 200-plus feet deep.
  3. The footings (which are like big pads that spread out the weight) should be placed at the bottom of the hole. The footings should be placed on stable ground, which is often the bedrock.
  4. Concrete should be poured over the footings.
  5. The vertical support beams should be constructed and well placed using large cranes. These are used to support the vertical load.
  6. The horizontal steel girders should be placed between the vertical beams which are used to bind the building together.
  7. The outside walls, which act like curtains, should be placed and the building is finished off.
