Foundation stone laid for Cube One of UTN

Foundation stone laid for Cube One of UTN (University of Technology Nuremberg)

Posted on 21 November.

Since the purchase of the land by the State of Bavaria, the LGA Institut für Umweltgeologie und Altlasten GmbH has accompanied the formation of the UTN – the new Technical University of Nuremberg.

On November 18, 2022, Prime Minister Dr. Markus Söder then laid together with the Science Minister Markus Blume, Construction Minister Christian Bernreiter, the founding president at Nuremberg University of Technology, Prof. Dr. Dr. h.c. mult. Hans Jürgen Prömel, and the Mayor of the City of Nuremberg, Marcus König, the foundation stone for the first building on the campus – Cube One.

The LGA Institut für Umweltgeologie und Altlasten GmbH contributed to the quick realization of the building project with the investigation and remediation of contaminated sites, with the supervision of the site clearance and with the preparation of a contaminated site and subsoil expertise (in cooperation with LGA Baugrund GmbH). Even the radon concentrations in the subsoil were measured by the LGA Institut für Umweltgeologie und Altlasten GmbH investigation department and the radon activity concentrations for the future building were estimated – harmless.

The LGA Institut für Umweltgeologie und Altlasten GmbH was also allowed to participate in the structural planning and in the framework planning for the UTN. Their greatest concern, to prevent senseless soil disposal with gigantic emissions of CO2 and waste of diesel fuel through intelligent soil management, found its way into the planning and was laid down in a progressive soil management concept together with the environmental protection office of the city of Nuremberg. For the construction of Cube One, therefore, only a few hundred tons of soil from a fuel spill had to be disposed of via biological cleaning – a great success for the environment!

Mantelverordnung: introduction of EBV, adaptation of BBodSchV, DepV and GewAbfV

New Mantelverordnung: introduction of EBV and adaptation of BBodSchV, DepV and GewAbfV

Posted on 04 October 2022

In July 2021, the legislature published the new Mantelverordnung (“Regulation on the Introduction of a Substitute Construction Materials Regulation, on the Revision of the Federal Soil Protection and Contaminated Sites Regulation and on the Amendment of the Landfill Ordinance and the Commercial Waste Ordinance”).

Although the regulations of the Mantelverordnung will only come into force on 01 August 2023, the new requirements may already have to be taken into account in current tenders and in construction projects whose execution begins before this date. Among other things, the scope of testing (parameters) and testing methods will be changed, so that old analysis results (e.g. according to LAGA M20) will only be comparable to a limited extent.

Classification of mineral waste

Processing of crushed concrete

Substitute Construction Materials Ordinance (EBV)

The most important item is the introduction of the Substitute Building Materials Ordinance (EBV), which for the first time sets out nationwide and legally binding requirements for the production and use of mineral substitute building materials (including recycled building materials from construction and demolition waste, soil and dredged material, gravel for railway tracks). The EBV thus replaces, among others, the LAGA M20 leaflet.

Further information on the new regulations can be found here.

To give you an overview of the most important changes and help you prepare in good time, we have produced a brochure that you can download here:

3D laser scanner measures and visualizes rock cellar in road embankment

3D laser scanner measures and visualizes rock cellar in road embankment

Posted on May 10, 2022.

Determining the exact position of rock cellars or caves in relation to the ground surface requires precise surveying techniques. The smallest angular errors can “warp” the entire model and cause several meters of positional deviation above a certain corridor length, which is an unacceptable inaccuracy, especially for questions concerning building and traffic infrastructure.

With a high-precision survey using a 3D laser scanner, we were once again able to record three rock cellars, whose entrances are located in the street embankment, with centimeter accuracy and visualize them under city ground. Not only the location in relation to the above-ground use (building, open space, traffic area), but also the cover of the cellars could be reliably determined. In addition to the geological recording of the vaults, the cover and its structure is one of the decisive parameters for evaluating the geological stability of the cellars.

However, the all-clear was given for the recently inspected basements. Besides a few structures in need of monitoring, the basements were mostly in good condition. The monitoring program is used to determine whether the monitored structures need to be rehabilitated or technically secured in the long term if their condition deteriorates.

Successful participation in various round robin tests

Successful participation in various round robin tests

Posted on 07 March 2022.

The quality of sampling determines the accuracy of expert statements. Errors made here can no longer be cured in the subsequent steps.

For this reason, we attach great importance to quality assurance in our company (more information hier). Interlaboratory tests and comparative measurements are also an important part of this. On the one hand, interlaboratory comparisons offer testing laboratories the opportunity to compare the results of their testing procedures with those of other testing laboratories under standardized conditions. In this way, their own performance can be reliably checked. On the other hand, monitoring authorities use the evaluation of the interlaboratory comparisons to decide on the compliance with qualitative approval requirements of individual testing laboratories. In 2021, we participated in the following round robin tests and comparative measurements:

Sampling on a property contaminated with explosives in Kempten, Germany

Round robin test on explosive residues in soil     The Federal Environment Agency had invited engineering companies to this round robin test in Kempten. A plot of land contaminated by explosives was to be representatively sampled according to the rules of the “art of contaminated sites” (area composite sample of topsoil, effect pathway soil – man). Dr. Kunibert Eberlein and Simon Landgraf from our company were represented.

 

Round robin test for soil sampling from trenches
At this event, organized by the Bavarian State Office for the Environment (LfU), all testing laboratories approved in Bavaria according to §18BBodSchG were present. Both walk-in trenches and non-walk-in trenches (from the excavator shovel) were sampled. Dr. Kunibert Eberlein and Hendrik Belz participated for the LGA..

Comparative measurement of groundwater sampling from a measuring point
In cooperation with four other offices or laboratories, we organized a comparative measurement at a groundwater measuring point. The analysis results (5 samples each for heavy metals and further inorganic parameters, 10 samples for LHKW), were comprehensively statistically evaluated. Fabian Ziegler, Hendrik Belz and Gerold Neumann participated from our office.

The results of the round robin tests on explosives residues are still pending.
The round robin tests for sampling at accessible and non-accessible excavations will be presented on 30.06.2022 within the framework of the GAB’s contaminated site symposium.
The statistical evaluation of the groundwater sampling was carried out by AIR – Analytik Institut Rietzler GmbH using the round robin evaluation software A45 from AQS Baden-Württemberg. In addition to the standard deviation of the on-site parameters, the zu-scores were determined for the individual samplers for the investigated organic and inorganic parameters. The results were made available to all test participants in a final report.

DAkkS supervisory audit confirms the high quality of our sampling

DAkkS supervisory audit confirms the high quality of our sampling

Written on February 05 2022

On October 21, 2021, one of the regular supervisory audits by experts from the DAkkS (German Accreditation Body) took place at our company.

The report now available attests to our staff’s very high level of competence in sampling soil, soil gas, building substances and waste.

Our accreditation according to DIN EN ISO/IEC 17025 as well as our admission as Examination Center according to § 18 BBodSchG are thus confirmed.

Our services around sampling and measurements you will find here.
