Membership in the RAL Quality Association “decontamination”

Posted on 6  August 2024.

We are pleased to announce our new membership in the RAL Gütegemeinschaft Schadstoffsanierung e.V.. As a reliable guide for companies and public clients, the RAL quality mark stands for high-quality, safe and reliable services as well as for neutrality and transparency. The “Schadstoffsanierung im Bestand” (decontamination in existing buildings) certification mark defines quality standards for remediation companies as well as for planning offices and expert activities and ensures compliance through annual inspections.

We are particularly pleased that our colleague Dominik Kisskalt was elected second chairman of the Quality Association at the general meeting on June 19, 2024.

On 29 July, the initial inspection for the assessment group of specialist planners/appraisers took place. We are currently awaiting the results and will report here when they are available.

Successful recertification according to ISO 9001

Abbruch von acht 33 m hohen Kohlesilos am Kraftwerk Nürnberg-Sandreuth der N-ERGIE AG

Posted on 16 April 2024.

In order to create space for new facilities at the Sandreuth site of Nuremberg’s N-ERGIE AG, eight silos from the former coal-fired power plant were to be dismantled. The 33 m high reinforced concrete structures posed particular challenges for the planning and execution of the demolition work, especially due to their immediate proximity to parts of the plant that were still in operation.

LGA Institut für Umweltgeologie und Altlasten GmbH was commissioned with the preliminary investigation of contaminants as well as the ongoing construction supervision. This also included health and safety coordination and an accompanying measurement program for dust and noise immissions as well as vibrations by LGA Immissions- und Arbeitsschutz GmbH.

Fire dampers containing asbestos – New VDI guideline

Posted on 18 March 2024.

Almost all fire dampers produced up to 1988 contain components containing asbestos. Millions of these old dampers are still in use. We have already reported on this several times (see articles from April 2021 and December 2021).

The new version of the asbestos directive (November 2020) now clarifies that an individual assessment of the condition must be carried out by the builder/owner. In March 2021, the German Association for the Restoration of Hazardous Substances (GVSS) initially published “Recommendations for handling fire dampers containing asbestos”. Ms. Weiblen, Mr. Malkmus and Dr. Kisskalt from our company were involved in the drafting process.

Based on this publication, the VDI founded a committee to draw up a VDI guideline on “Asbestos-containing fire dampers” (VDI 6202 Sheet 3.1). Our colleagues were again represented here. Dr. Kisskalt took over the deputy chairmanship of the committee (Chairman: Mr. Olaf Dünger). In a very short time – for guideline committees – a draft was prepared and finished in a final reading in the committee on 28.11.2023, which is to be published shortly as a green print (probably in April 2024).
