The construction industry is continually undergoing further development, and in so doing places new requirements on planners and those in charge of construction projects. Whether this be the size of a project or its complexity.

Measurements are the basis of all projects, because literally every millimetre matters.
Whether this be engineering surveying, precision measurements, laser scanning, tunnel surveying or control measurements – with our level of measurement accuracy, we create the basis for your projects.

Using state-of-the-art electronic tools, technical plant, buildings and relevant topography are recorded and represented.

With these precise results, for example, unstable natural circumstances can be calculated and suitable measures for changing the previously hazardous or even life-threatening situations can be initiated. Human life and nature can then be effectively protected.
The expected requirements placed on machines and the materials used also necessitate reliable calculations in advance, in order to ensure their permanent use also under extreme conditions. This is not possible without have exact measurement data.

Precision measurements are to be found everywhere. They are needed in the construction of or when maintaining a tunnel (surveying the tunnel cross-section) and when monitoring construction to establish differences in the weight of columns. Precision measurements are used to determine building and ground elevations or during the construction phase to check that the center line conditions are observed. These are also essential for working out the entire assembly logistics of large-scale building facades.

The field of engineering surveying is always a focal point and has to provide exact measurement data in order to guarantee an effortless assembly and the sustainability of the materials used for the project. In this way, each phase of construction is monitored and documented exactly by us. When planning large-scale plant buildings such as, for example, power plants, a multitude of installation parts, formwork, openings, lines and pipes have to be calculated before the final concrete is poured and their positions defined.

The global interest in German surveying technology and in particular the trust placed in us time and again by many well-known customers shows that our spectrum of services and our competence not only complies with the needs of the market, but also more than fulfils the expectations of our customers.

This competence is based on 120 years of experience and the philosophy to always be at the forefront in developments in the construction industry. Whether this be new measurement methods, more exacting instruments or improved presentation of results – we possess the latest technology for data compilation and evaluation.

Thus, we are in a position to undertake highly precise data recording according to deadlines, with a clear and calculable amount of effort as well as reliable cost calculations.

Because competence also has to take both logistics and economics into consideration.

Naturally our employees are always up-to-date with the latest developments and continue to pursue their further training. Because not only technology keeps on developing.


Continuity means for us in the Heitkamp family not only the successful continuation of the surveying division.

Above all, continuity also constitutes for us the continued and long-term support of projects from the first draft to completion and beyond. Because our responsibility does not just simply come to an end upon completion of in particular large-scale projects.

Besides terrestrial surveying, the calculation of material requirements up to storage, static load calculations or accessibility and infrastructure planning, we also therefore provide monitoring. For example, sensors control any subsidence during construction, if applicable.

Sensors also monitor the finished buildings and constructions later on, for example, for subsequent subsidence and deformation such as for facades or in tunnel construction. The checking of changes to the terrain can also be necessary in certain cases in order to safeguard the building site.

We will accompany your project from the initial idea to when it goes into usage. That is what we call continuity.



Laser scanning is one of the most important fields of activity in engineering surveying. Because whenever surveying measurements have to be undertaken on very large construction projects, extensive terrains or complex building sites, laser scanning is the method of choice. By scanning the surface with a laser beam, multi-dimensional images can be produced which correspond to reality.

The areas of use of the laser scanning procedures are manifold: whether for surveying complex building architecture, when planning facades, in bridge construction, in road construction, when planning landscapes, in complicated roof construction (football arenas), this procedure is even used in boot construction to achieve exact measurement results.

The altered use, new planning, refurbishment or rededication of e.g. parts of buildings, roadways or open spaces always requires a comprehensive review of the previous usage. A multi-dimensional image simplifies and supports planning of the new requirements for the respective object. Thus, possible weak points which are critical to the project can be analysed and included in the planning in advance.

Laser scanning is the method of choice when the altered usage of parts of buildings makes new static load calculations necessary or if a profile of the terrain has to be prepared to facilitate weight calculations. With the help of a scatter plot

exact, very exact and  detailed images of the real structure of the object can be created.  Even poorly accessible building areas can be surveyed and reproduced in 3D to a realistic scale.
The combination of the comprehensive review of the previous object and the new planning for this object augment one another as an optimal planning tool.

Detailed measurement and presentation of complex structures cannot be achieved with other measuring procedures. Huge buildings such as for example the Cologne Cathedral or the Eiffel Tower can be depicted with the help of the laser scanning procedure in order to plan repair or maintenance work. And at the same time in a significantly shorter period would normally be required with conventional methods!

Compared to conventional measurement methods, the time saved in erecting scaffolding for the objects to be surveyed in combination with the significantly lower time needed for the actual measurement make an objective cost-benefit assessment appear almost without a reasonable alternative.
