Planning for the construction of transport pipelines

Under the leadership of igr AG, the ARGE "Regionales Verbundsystem Westeifel" (Westeifel Regional Combined Systems) delivered the authorisation documentation for a pioneering, innovative infrastructure project to the authorisation authorities. In an 83 km long shared trench, from the Belgium border to Trier, a water pipeline, a natural gas pipe, a biogas pipe, a 110 kV and a 20 kV powerline and a high-speed internet fibre optic cable will be laid.

igr prevailed against European competitors in a tender process under VOF regulations, and received a contract award for technical planning as well as for the areas of environmental impact assessment, nature conservation and species protection. In only six weeks, the routes were tacheometrically surveyed and represented as a digital terrain model. This was the basis for establishing the depth of individual utility lines. The short planning period could be successfully met due to a specific geographical information system (GIS). Through intersections problems with private properties, and with existing pipelines, forest clearances, water conservation areas (and other types of conservation areas), and almost 90 road and waterway crossings were quickly recognised and solved.

Bann Pirmasens Studie Flaechenmanagement

Study of threatened and endangered species, federal properties in Bann and Pirmasens, districts of Kaiserslauten and southwest Pfalz

Through the extensive use of the military property and the especially dry and tough local conditions, meadows and wooded areas of high ecological value have evolved on the greater part of the plan area. In addition, the bulk of Husterhöher barracks in Pirmasens is recorded as a "habitat-mapped" area and in part totally protected in line with § 30 Federal nature conservation law (BNatSchG).

The comprehensive examination of the faunistic stock, concentrated primarily on animal genera adapted to the dry and poor local conditions. This mapping documented the biodiversity and the development of the location over a period of 5 to 10 years – for example, the decline of the blue-winged grasshopper (Oedipoda caerulescens) and the growing population of red-backed shrikes (Lanius collurio) due to the increase in scrub areas.

The study also confirmed new indicator species of some very rare and heavily endangered species (German Red List) on dry, partly scrub open locations, such as the purple-shot copper (Lycaena alciphron) and the glanville fritillary (Melitaea cinxia).

igr compiled goals and individual measures of varying priority, such as for example protection of special areas, grove clearing, turf removal, grazing and a variety of gentle technical methods, as well as a monitoring programme to protect and optimise the habitat mosaic, with ca. 65% open land, 25% partly open land and 10% trees/wooded areas.

Services provided by igr

  • Systematic mapping of fauna (birds, butterflies/moths, grass hoppers, dragonflies, amphibians, reptiles)
  • Extensive documentation of the current situation
  • Management planning

Key figures

  • 6 ha Bann A and B Air/Telecommunication Station
  • 60 ha Husterhöher barracks, Pirmasens (and surrounding area)

Car parks planning/all year round design for the Rennsteig in the Thüringer forest

As part of the all year round design for the Rennsteig, five car parks in the Thüringer forest were planned by igr. igr was responsible for the technical specialist planning and the environmental management supplementary plan. In total, the car parks Schmiedefeld, Kalte Küche, Schillerbuche, Neustadt und Hohe Sonne in the Thüringer forest were developed. The car parks are to be upgraded and modified with improvements planned in the asphalt surfaces, so as to improve the tourist facilities at each site. The car parks are sited along the well-known Rennsteig footpath – the oldest long distance footpath in Germany, which has a total length of 170 km and is visited by 100,000 hikers annually.

igr created an environmental management supplementary plan in line with the Thüringer balancing model (encroachment and compensation balancing corresponding to the significance of the biotope types that are present). In addition, the investigation areas were analysed with regard to possible nature conservation areas (FFH zones, Bird sancturies, and other categories). Some car parks are inside the "Vessertal-Thüringer Wald" biosphere reserve and the "Thüringer Wald" nature reserve. These special situations were taken into account accordingly and exemption applications in line with § 67 Bundesnaturschutzgesetz (BnatSchG) were made.

With regard to the encroachment on nature and the environment, with agreement of the lower nature conservation authority in the respective state districts, appropriate compensation measures within and outside of the planning area were implemented. In order to ensure the efficiency of the planned environmental management measures, environmental construction supervision ensured that the construction related encroachments were minimised, and the compensation measures undertaken. The technical and ecological construction supervision undertaken by igr, ensured the smooth implementation of the measures under consideration of the conditions of the authorisation permit.

  • Environmental construction supervision
  • Landscape (environmental) management supplementary plan
  • Exemption applications

Key figures

  • Construction related encroachments: ca. 12 ha
  • External compensation measures: ca. 15 ha

Site development plan for "Hinter der Bahn" in der town of Wörrstadt, district of Alzey-Worms

The municipality of Wörrstadt, in the district of Alzey-Worms, wishes to meet the demand for residential building land, and to designate a 8 ha site as a development site.In order to take sufficient account of concerns about environmental protection in the weighing up process, an environmental report is to be undertaken.

The development area covers farmland and highly structured gardens.Of particular interest in the planning and balancing measures, is the ambitious conservation of existing groves, and the renaturing of the mill races bordering the site.

  • Site development plan
  • Environmental report
  • Encroachment/compensation balancing
  • Storm water management design

  • 8 ha area of interest for the site development plan
  • 1 ha flood plain (HQ 100)

Special area for wind energy farms in the Glan-Münchweiler municipality, district of Kusel

The Glan-Münchweiler municipality has set itself the goal, of meeting the electricity demand increasingly from regionally available renewable energy.So as to make suitable areas available, the municipality has agreed a "wind energy" sub land development plan, in which nine special areas for wind energy use with a total area of 403 ha are to be designated.Together with the already existing special "wind energy" areas, the municipality has now designated a total of 447 ha for wind energy special areas.

In order to address the associated environmental protection concerns, an environmental report was prepared, which, in compliance with the UVPG (environmental compatibility test) considered and assessed the encroachment on protected resources such as:soil, water, air/climate, landscape, animals/plants, humans or other cultural/physical objects.

In accordance with the investigated encroachments on the ecosystem and landscape, extensive avoidance and compensation measures were specified.Through these measures, the negative effects on nature and the countryside could be compensated for, and/or prohibitions as outlined in § 44 BnatSchG be avoided, on the basis ofthe up-to-date database (amongst other things, optimisation suggestions with regard to red kite breeding or crane migration).
