Working throughout the UK and overseas, Severn Partnership uses the latest robotic survey equipment, 3D laser scanning technol- ogy and 3D modelling software. They offer profes- sional services in geomatics, railway survey services, utilities survey to 3D and building information model- ling (BIM), and mixed in a wealth of survey expertise and experience. In 2014, Severn Partnership made a significant investment in the Leica Pegasus:Two, the new mobile mapping solution from Leica Geosystems, becoming the second company worldwide to adopt this new technology. The Leica Pegasus:Two enables Severn Partnership to scan an impressive 1 million points per second with 120 metre (390 foot) range, resulting in survey grade data being captured in a fraction of the conventional survey time.

If it is not properly addressed, fire in a tunnel can result in loss of life to both tunnel users and the fire and rescue services. The result- ing economic losses for both the tunnel owner/operator and to the local economy and environ- ment can be catastrophic. This document is the result of a co-operative effort between the World Road Association (PIARC) Technical Committee on Road tunnel Operation (C 3.3) and its Working Group 6 Fire and Smoke Control, and the International Tunnelling Association (ITA) Working Group 6 Re- pair and Maintenance of Underground Structures. The purpose of this co-operative effort is to develop guidelines for resistance to fire for road tunnel structures.

  • 5. Noise Pollution
    5. Noise pollution 1. Please describe the present situation and development over the last five to ten years in relation to (max. 1,000 words): Within the scope of implementing “Directive 2002/49/EC of the European Parliament and the Council of 25 June 2002, relating to the assessment and management of environmental noise”, the proportion of Hamburg’s population subjected to noise emanations from road, railway and air traffic sources as well as industrial, commercial and port facilities has been determined in terms of the noise indicators L den, for noise levels during the day, evening and night, and L night, for noise levels at night. The assessment was calculated on the basis of national provisional computation methods; namely, the “Provisional computation method for environmental noise on roads – VBUS”, the “Provisional computation method for environmental noise on railways – VBUSch”, the “Provisional computation method for environmental noise at airports – VBUF”, the “Provisional computation method for environmental noise from industry and commercial facilities – VBUI”, and the “Provisional computation method for determining the number of individuals exposed to environmental noise – VBEB”. In terms of the industrial, commercial and port sector, in addition to plants located in the port area, only those industrial or commercial zones with one or more plants as per Appendix 1 of the “European Council Directive 96/61/EC of 24 September 1996 concerning integrated pollution prevention and control” are afforded consideration. The period of reference is 2006. Accordingly, the number of individuals affected is as follows: Affected by L den > Affected by L night > 55 dB(A) 45 dB(A) Road traffic 363600 420900 Rail traffic 56200 38900 (L night > 50 dB(A)) Air traffic 43700 5000 (L night > 50 dB(A)) Industry/commercial 4200 10200 /port facilities In line with the requirements of the EU directive, the analyses are updated at least every 5 years, from which commensurate developments regarding issues of concern can be ascertained.

  • Read the Executive Summary of the Bottleneck Analysis Here
    STRING bottleneck analysis for the stretch Oslo – Hamburg Prepared by KombiConsult GmbH (lead partner), Ramboll Norway, Ramboll Sweden and Ramboll Denmark Summary February 2021 Seamless transportation is a prerequisite 1 for growth A high-quality transport infrastructure with sufficient capacity and which is managed efficiently is fundamental for the competitiveness of the economies of the Member States of the European Union (EU). The EU has been contributing to ensure the goal above, amongst other instruments1, through the trans-European transport network (TEN-T) policy. The primary objective for The EU “is to establish a complete and integrated trans-European transport network, covering all Member States and regions and providing the basis for the balanced development of all transport modes in order to facilitate their respective advantages, and thereby maximising the value added for Europe”. The STRING stretch is an integral part of the TEN-T Core Network Corridor Scandinavian-Mediterranean (Scan-Med)2 and already shows a high quality, today. However, and in particular with view on the envisaged completion of the Scan-Med corridor by 2030, still some gaps are expected to remain from today's point of view. Transport and infrastructure bottlenecks can affect the normal flow of transportation, causing unnecessarily long travel times, delays, congestions, costs etc. KombiConsult GmbH and Rambøll have analysed the existing bottlenecks in the STRING - geography outlining future recommended priorities. This paper is a summary of the main findings of the analysis. 1 The White paper 2011 “Roadmap to a single European Transport Area – towards a competitive and resource efficient transport systems with the goal of “A 50% shift of medium distance intercity passenger and freight journeys from road to rail and waterborne transport”.

During operation, a large diameter tube allows for stacked deck configuration with shafts dropped to platform level (no station caverns). The extensive information has been compiled on innovative TBM tunneling projects such as the Barcelona Line 9, where the concept of continuous station has been used for the first time, stormwater management and roadway tunnel in Malaysia, where the floodwater bypass tunnel and the road tunnel are incorporated in a single bore tunnel.
