Engineering Surveys refer to the various surveying tasks that are done on a construction site in support of engineering needs. As construction surveyors, we gather data to enable planning of construction activities. These various stages of building and construction require some survey measurements and output.

We assist in activities such as design of a projects, collecting data enabling sewer line designs, storm water designs and the design of the physical dimension of buildings and civil structures.

Our expert skills also help in the design of elevations and levels of structures in building and construction projects.

Professional engineering surveying in the construction phase means accurate setting out of design elements. This refers to the actual placing of structures on the ground, placing correct levels on structures and marking out positions of each civil structure or building. Therefore we ensure accurate positioning, making sure the design shape and size is achievable.

Typical Projects For Construction and Engineering Surveys

Our services offer excellent solutions to dimensional aspects of engineering projects of various forms

Construction of Roads and railways – topographical surveys for design, as well as setting out of road curves and routes. We survey through-out the project directing levels for different layers and ensuring compliance with project specifications

Construction of Bridges and Civil Structures

Redshadow Engineering Surveyors provide accurate surveying services for the construction of bridges and other civil projects such as tunnels and pipeline projects

On site surveys for power station activities – the setting out of steel structures, civil structures and other buildings in the power station construction projects

Dam surveys – setting out and monitoring surveys

Similarly, we perform surveys for recreational facilities. Such surveys enable the planning and design of recreational facilities and well as game reserves

Alignment surveys for such equipment like overhead cranes. We therefore make use of specialized equipment to ensure the crane rails are accurately erected

A construction surveyor works in many civil construction projects as well as other engineering projects, such as mechanical machines. Let us look at what a construction surveyor is expected to offer and what he/she should do to get the desired results.


Data furnished to civil engineer for design purposes

Sometimes known as engineering surveyors or topographical surveyors, construction surveyors normally begin work well before site  establishment. A topographic survey usually precedes any form of work on a site. Before a civil engineer can come up with a design, he or she requires certain information about the topography of the area of interest.

The single most important product of a topo survey is the contour map. Engineers need contour maps for them to design how the finished structure and ground should look like. Such finished structures such as drainage systems and structure relationship with other utilities. Therefore a topographic survey forms part of the initial data requirements for design. So an engineering surveyor goes out to survey the land first, for two primary reasons. The first one is to map the positions of existing features, such as trees, rivers, streams and any existing man made feature like roads and buildings. The second one is to produce contours to show the existing ground undulations for design purposes

Construction surveyor services on site

Once a civil engineer has completed his or her designs and drawings, construction surveyors can proceed with setting out surveys. Setting out survey refers to the measurements taken by a surveyor to transfer drawing positions to the ground with precision. Let us say, for instance, a drawing suggests that the finished ground levels should slope at 1% gradient, from a certain position to another. The engineering surveyor should survey and mark out positions on the ground that should guide contractors to achieve that.

Setting out surveys are done for ground preparations during earthworks, and during erection of structures to guide contractors with levels and positions of structure. For a steel structure, setting out might involve marking out the positions of holding down bolts, for which steel columns will be fixed. A surveyor on site will typically set out positions of concrete columns and bases, from the position of shuttering to the actual concrete position. Most engineering drawings come with grid lines. Surveyors on site can mark out grid lines to give the contractors a point of reference. All that is part of setting out.

Construction Surveyor : Other Services on site

Site surveyors also provide alignment survey services. These surveys can be either for structural steel, mechanical or civil structures. A good example is the alignment of crane rails on site. It is crucial for erection teams to work closely with engineering surveyors in order to get positional guidance. Surveys also enable to achieve high accuracy and avoid re works due to errors in positioning. Absence of surveyors on site results in unwanted demolitions of portions of structures due to misalignment. Clash of positions of structures is also common or even malfunction of design features. It is more costly to run a construction site without surveyors than to employ surveyors, especially for large projects.

As built surveys

As built surveys are done as the final record of measurement of structures, as a final record keeping. It is important to record and maintain the positions of structures and have a comparison with the design positions. Sometimes it happens that, while erection teams are busy with their work, there can be unwanted movement. Examples are the movement of shuttering during concreting. Such a movement can alter the position of a concrete structure as it dries. An engineering surveyor should record the final positions for analysis. Sometimes it may be necessary to break a portion and have it redone if the engineers sees it fit.

Distinction between professional land surveyor and engineering surveyor

For the general populace, an engineering surveyor can be loosely referred to as a land surveyor. However, this may be misleading in the scope and extent of duties.

In South Africa, a professional land surveyor is a surveyor who is so registered with the South African Geomatics Council (SAGC) formally known as PLATO. Land surveyors in South Africa have a license to perform demarcation surveys and sign off for lodging at the Surveyor General’s Office. These surveys, known as cadastral surveys, form a legal basis for title of properties. Land surveyors therefore, can perform any survey be it engineering or cadastral surveys. On the other hand, however, a construction surveyor may not perform cadastral surveys without supervision by a registered land surveyor.

Construction Surveyors Pretoria – What We Do

If you are wondering how builders contractors manage to transfer the information from drawings to the ground without error? The answer lies with the use of technical personnel called construction surveyors. Construction surveyors are responsible for transforming positions and levels from the drawings to the ground with guaranteed precision and accuracy.

This process of transferring positions and levels from the drawing to the ground is known as setting out. Therefore it is common practice that before any construction works actually begins, a site surveyor or construction surveyor should mark out the extent of the structure on the ground. In fact, setting out precedes any construction works.

Engineering surveyors/site surveyors also monitor the positions and levels of buildings as construction progresses until the finish. Imagine that a civil engineer has a design of a concrete base on which a large water storage tank should sit. And supposing that the concrete base is circular, and that it follows a cone shape, the slopes following a specific gradient that should be met to a certain degree of accuracy. It is then the duty of a surveyor to give guidance and ensure the following,


(a) The center of the base is exactly in position and has exact coordinates from interpolation or calculation from the drawing

(b) The radius of the base is of a dimension in the design specification of the drawing

(c) The final finish level and the slope is as per drawing

(d) The final structure’s measurement is comparable to its design positions


Where do construction surveyors work on site

A construction surveyor or site surveyor may work on all or one of the following broad construction sub sections

  1. Civil structures such as concrete columns, bases and slabs
  2. Structural steel frames , such as main primary steel, secondary steel or other steel frames attaching to secondary frames.
  3. Overhead crane rail surveys, alignment and leveling
  4. Piping
  5. Machinery alignment and positioning
  6. Earthworks – determining volumes of masses of sand or raw minerals
  7. Dam structures
  8. Bridges
  9. Roads
