Efficiency, Safety, and Sustainability through Innovative Technology

Efficiency, Safety, and Sustainability through Innovative Technology

STRABAG leverages innovative technology to make work more efficient, improve worker safety and drive sustainability in urban areas.

Geospatial technologies and surveyors play a crucial role in developing infrastructure and green transportation projects to make cities more inclusive and resilient. Utilising advanced surveying tools, surveyors can accurately and efficiently capture data essential for modernising infrastructure. Geospatial data is key for sustainability projects including making cities safer for cyclists, redesigning bus stops to accommodate longer buses or improving accessibility for individuals with disabilities. The use of geospatial technologies and the continuous innovation in surveying equipment streamlines the urban development process and contributes to creating sustainable, equitable, and resilient cities with improved infrastructure and green transportation systems.

Building more sustainable, equitable, and resilient cities requires planning, constructing, and maintaining infrastructure. This includes a focus on smart mobility and green infrastructure. Across the world, cities are transforming this vision.

How geospatial data helps build resilient, inclusive infrastructure

The transformation of cities into more sustainable, inclusive, and resilient environments requires the collaboration of various stakeholders, including surveyors like Dipl.-Ing. Lothar Lyschik. With nearly four decades of experience, Lyschik leads the surveying activities of the Traffic Route Construction Division of Munich and its surrounding communities at STRABAG AG, the No. 1 traffic route construction company in Germany.

Toward a more inclusive and greener city

Lyschik and his team at STRABAG AG have successfully completed three recent projects in Munich, including the reconstruction of a bus stop, the redesign of public squares, and the conversion of intersections for improved traffic routing.

The bus stop was redesigned to accommodate longer towing vehicles and to provide easier access for individuals with mobility limitations, with an appropriate height for those with disabilities. The team also helped enhance Munich’s public squares by adding more green spaces, comfortable seating, and a more harmonious aesthetic that prioritises pedestrian accessibility. To improve safety, STRABAG also converted intersections to better accommodate pedestrian and bicycle traffic, eliminating barriers and thresholds for individuals with disabilities. Cyclists, on the other hand, will benefit from a level crossing at the intersections.

Big projects, little time

Lyschik, an experienced surveyor with many years of experience, has surveyed numerous large-scale road reconstruction projects. The usual completion times range from a few months to two years, but to minimise the disruption to traffic, the construction work at intersections and other construction sites is conducted in sections with limited time windows. To ensure safety and timely completion, STRABAG AG held weekly meetings to regulate the construction process and collaborate with other units.

We are only given a very, very small time window for certain conversion measures because individual traffic should be restricted as little as possible. Safety is a top priority for us, so securing the construction site is a crucial part of the construction process. We aim to prevent any accidents from happening during construction.

Reliable partners in a dense traffic area

When working in dense traffic areas, surveyors use state-of-the-art surveying equipment that helps them do the job safely within the short timeframes given.

Surveying innovations that did not exist a few years ago are a great advantage, especially for documentation. New surveying technology enables measurements on uneven surfaces, from difficult positions and from any angle. This facilitates and speeds up measurements, for example, in areas around subway shafts or in traffic islands that are equipped with signs or light signalling systems. In places with enough visibility to the sky, surveyors use a satellite-based navigation system to map construction projects without risking line-of-sight interruptions from traffic.

Surveying crews have become smaller over time and technology has transformed how surveyors work.

Field and office surveying software that fits city demands and regulations

Lyschik precisely recorded all details of the traffic surface, including carriageways, footways, cycle lanes, and traffic islands, with the accuracy and format required by Munich’s template catalogue. Complex data processing is enabled by surveying software that collects survey data from different instruments and generates precise 2D views and 3D models. Geospatial office software, meanwhile, enables continuous data exchange between the field and the office, allowing teams to work efficiently with real-time data.

Leveraging geospatial technology

With nearly four decades of experience, Lyschik has witnessed how surveying crews have become smaller over time and technology has transformed how surveyors work.

Surveyors have become lone wolves. When I was a student, the measuring team still consisted of three people. Over time that has been reduced to two, and I would say that with the one-man station, we all work alone now.

Finding coordinates in new areas used to take up to one day or even longer. Thanks to GPS or GNSS positioning, the same can now be done in much less time. Lyschik has personally experienced the advantages of these innovative tools, which have simplified his work by eliminating the need for manual surveys. Utilising cutting-edge technologies like GNSS in combination with image capture has not only saved time for Lyschik and his team but has also made their work more manageable while minimising exposure to potential hazards.

When new innovations emerge in surveying equipment, STRABAG AG proactively integrates them into its daily workflows to improve efficiency, expand its service offerings and enhance safety measures.

Construction firms such as STRABAG play a pivotal role in transforming cities into sustainable, inclusive, and resilient environments. Technological advancements enable surveyors to complete projects with greater accuracy and speed, streamlining the construction process and creating better infrastructure for all.
