Measurement technology

Our core measurement technology competencies cover both planning and carrying out static and dynamic pile tests. Our dedicated employees put our expertise into action to guarantee optimised pile tests for our internal and external partners. Our tests are based on accepted national standards (Empfehlungen des Arbeitskreises Pfähle, or EA-Pfähle) and customised schemes.

Using our range of steel girders and calibrated presses, we can match the specific requirements for your individual construction project and structure. We carry out static pile tests up to 20 MN and can increase the test load up to 24 MN using load crowns.

We don’t just carry out the pile tests: we can also provide instrumentation, in the form of vibrating wire sensors and fibre optics. We can also carry out long-term monitoring for combined pile-raft foundation.

Clients nowadays often request a paper trail from the execution stage of a construction scheme, so they can store evidence about any negative effects on the urban surroundings. We carry out vibration measurements, including monitoring existing buildings for negative effects of vibration related to the construction site.

The client can use this evidence to counter any unjustified claims. We can also test for specified threshold and alarm values, so that countermeasures can be implemented before any harm occurs to buildings or people. Any necessary safety measures can be introduced at an early stage. 

We have been using fibre optic instrumentation since 1990. Two of our early measurement technology projects were Denmark’s Great Belt Bridge and the permanent anchors for the Edersee Dam.

Fibre optic technology experienced a renaissance in specialist civil engineering in 2014, thanks to distributed strain sensing and distributed temperature sensing.

Following the success of distributed strain sensing in the specialist civil engineering domain, PORR has established itself as one of the top providers of fibre optic instrumentation in the specialist civil engineering sector. We have also produced two key publications about distributed strain sensing for construction technology.  

When your construction includes installing narrow piles or large bored piles, it’s essential to carry out prior checks. We carry out integrity tests to identify any misalignments at a stage when you can still correct errors, before the piles are covered by the building structure. That way, you avoid damage to buildings and can arrange any necessary corrective measures at an early stage.

Our experienced team carry out low-strain and cross-hole integrity tests, guaranteeing the safety of your structure and enabling you to optimise quality.

Environmental protection and occupational safety requirements often stipulate that noise monitoring is carried out during construction projects. Sound emissions are measured, using appropriate technology, in the area where the construction work is in progress. 

Short-term measurements are then evaluated against threshold values in order to ensure the environment remains suitable for humans and animals.

In order to meet the requirements of environmental protection and occupational safety, many construction schemes monitor dust pollution. This involves measuring emissions around the construction activity using measurement technology to determine dust volumes, particle counts and particle sizes.

The measurements are then evaluated against specified thresholds to ensure atmospheric pollution is kept within appropriate limits and to avoid harmful effects on people and planet. 

Ensuring quality requirements is a top priority at PORR. This is also evidenced by our certificates and approvals. In order to always be up to date, our certificates and approvals are reviewed and updated on a regular basis through external audits and independent certification companies.

In addition, independent companies, such as Deutsche Bahn AG, confirm our skills and actions through prequalifications and special recognition.
