What is the Purpose of Surveying in Construction?

Surveying plays a crucial role in the construction industry. It involves measuring and mapping the land to gather essential information for the planning, design, and construction of buildings and infrastructure. This article aims to provide a brief overview of the purpose of surveying in construction, highlighting its positive aspects, benefits, and suitable conditions for its use.

I. Purpose of Surveying in Construction:

  1. Accurate Planning and Design:

    • Surveying helps architects, engineers, and construction professionals obtain accurate measurements of the land, ensuring precise planning and design.
    • It helps determine the boundaries, elevations, and contours of the site, allowing for effective decision-making during construction.
  2. Site Analysis and Feasibility Studies:

    • Surveying provides vital information about the site's suitability for construction.
    • It helps identify potential obstacles, such as uneven terrain, natural features, or existing structures, enabling developers to assess the feasibility of their projects.
  3. Construction Layout:

    • Surveying aids in the accurate positioning of structures, utilities, and infrastructure during construction.
    • It ensures that buildings are correctly aligned, levels are maintained, and foundations are properly established.
  4. Quantity and Cost Estimation:

Theodolite Surveying: It uses a theodolite. Theodolite is a precise instrument used to measure angles and distances. Chain Surveying: It uses chains or tapes to measure distances and angles. GPS Surveying: This method utilizes Global Positioning System (GPS) technology to determine accurate positions using satellites.

What is the main purpose of surveying?

The main objectives of surveying are as summarised below: To determine the relative position of any objects or points on the earth. To determine the distance and angles between various objects. To prepare a map or plan to represent an area on a horizontal plane.

Why is surveying useful?

Surveys provide researchers with reliable, usable, primary data to inform business decisions. They are important because the data comes directly from the individuals you have identified in your goal. And surveys give you a detailed, systematic way to view and analyze your data.

Why are surveyors necessary?

Importance of a Property Survey

A property survey will explore the house to discover any potential defects, floors, or potential risks to the structural integrity of the building. It can also be used to negotiate the price of the property.

What is the meaning of surveying in construction?

Construction surveying or building surveying (otherwise known as "staking", "stake-out", "lay-out", "setting-out" or "BS") is to provide dimensional control for all stages of construction work, including the stake out of reference points and markers that will guide the construction of new structures such as roads, rail

How do you conduct a construction survey?

Conducting a Site Survey. A site survey identifies any design, construction, or environmental limitations at a potential construction site. It involves a comprehensive examination of the site's topography, soil type, vegetation, climate, existing structures and utilities, and surrounding land use.

What are the steps of surveying?

To conduct an effective survey, follow these six steps:
  • Determine who will participate in the survey.
  • Decide the type of survey (mail, online, or in-person)
  • Design the survey questions and layout.
  • Distribute the survey.
  • Analyze the responses.
  • Write up the results.

Frequently Asked Questions

What are the 4 main ways to conduct a survey?

Conducting the Survey. The four main ways to conduct surveys are through in-person interviews, by telephone, through the mail, and over the Internet. As with other aspects of survey design, the choice depends on both the researcher's goals and the budget.

What are the basics of surveying?

Surveying is the science of determining the relative positions of objects or points on the earth's surface. These points may be any physical thing: a highway, culvert, ditch, storm drain inlet, or property corner. Distances and directions determine the horizontal positions of these points.

What is a site survey in construction?

Site surveys are inspections of an area where work is proposed, to gather information for a design or an estimate to complete the initial tasks required for an outdoor activity. It can determine a precise location, access, best orientation for the site and the location of obstacles.

What is the most important role of a surveyor?

Surveyors make precise measurements to determine property boundaries. They provide data relevant to the shape and contour of the Earth's surface for engineering, mapmaking, and construction projects.


What are the steps in surveying?
The Land Surveying Process (In 8 Steps)
  • Obtain existing deeds and property information.
  • Prepare a base boundary plan.
  • Do the field survey.
  • Prepare the existing conditions plan.
  • Resolve any boundary issues.
  • Obtain any other required survey information.
  • Prepare the construction stake-out survey.
What is the basic method of surveying?
Triangulation Surveying Method

The Triangulation method is a basic surveying method and is adopted when the surveyed area is large. The entire area is divided into a triangulation of networks by the surveyor.

What are construction surveying tasks?

The job role of a surveyor involves the following duties: Surveying properties to identify structural damage and make recommendations for repairs. Inspecting buildings for insurance purposes and advising on relevant legal requirements. Advising on energy efficiency and environmental impact.

What is the 3 4 5 method of surveying?

To get a perfectly square corner, you want to aim for a measurement ratio of 3:4:5. In other words, you want a three-foot length on your straight line, a four-foot length on your perpendicular line, and a five-foot length across. If all three measurements are correct, you'll have a perfectly square corner.

What is the purpose of surveying in construction

What are basic principles of surveying?

Two basic principles of surveying are: • Always work from whole to the part, and • To locate a new station by at least two measurements ( Linear or angular) from fixed reference points. area is first enclosed by main stations (i.e.. Control stations) and main survey lines.

What is the basic knowledge of surveying?

Surveying is the science of determining the relative positions of objects or points on the earth's surface. These points may be any physical thing: a highway, culvert, ditch, storm drain inlet, or property corner. Distances and directions determine the horizontal positions of these points.

How important is a building survey?

It will tell you any obvious major problems – obvious rot, subsidence, etc. It includes a valuation and an insurance reinstatement value (how much you would receive were the building to burn down).

  • Why surveyors are important in a site?
    • Whenever an individual or company purchases a property to develop it, land surveyors play an essential role. Land surveyors are responsible for mapping and measuring a property's land to establish property boundaries. They also provide information about the property's topography and existing buildings or improvements.

  • What are the three purposes of site surveying?
    • To determine the required areas and volumes of land and materials needed during construction. To ensure that the construction takes place in the correct realtive and absolute position on the ground. To record the final position of the construction, including any design changes.

  • What are the steps of the site survey?
    • Consider these 8 essentials for conducting a site survey.
      • Start With a Floorplan When Possible.
      • Conduct a Site Visit or Walkthrough.
      • Know Before You Go.
      • Learn What Every Space Is Used For.
      • Catalog Existing Infrastructure (If Any)
      • Document Everything in a Central (Cloud-Backed) Location.
      • Verify Access Control Needs.
