Every task which we take on for our customers offers a new challenge. Each time the focus is set on different services from our portfolio and different details. With these case studies we introduce you to selected projects which are exemplary for the services we provide.
Project: Line planning for eastern and northern region
By expanding its fibre optic network, Vodafone GmbH aims to significantly increase the capacity of its network. STF Tele Consult is supporting the telecommunications company in the planning and realisation of this highly complex project. Network topology, redundancy requirements and efficiency are the main issues.
With the help of STF engineers, Vodafone is not only able to connect its own locations to the network, but also to connect clients’ locations.
Project: Wireless network planning for shunting radio, analogue wireless train communications and mobile train communications
STF Tele Consult supports Deutsche Bahn in the planning and optimisation of radio networks in shunting radio, analogue wireless train communications and mobile train communications.
The planning and optimisation of the radio planning tool is based on a metrological network analysis. Our approach combined with the specialist expertise of Deutsche Bahn’s technicians ensures that the high demands concerning network availability and security are met.
Project: Quality assurance and network audit
STF Tele Consult assumes planning contracts for Telefónica as well as ongoing quality audits of locations and transmission networks. If errors in the quality audit of locations and construction quality are identified, such as in the antenna positioning, or in technical parameters, such as the transmission and reception range, STF engineers implement measures to eliminate the errors. Complex configurations and deviations between the planned and actual state represent regular challenges. The constant increase in network quality is a clear indication of the success of STF’s services.
In-house and building coverage
To ensure optimum wireless coverage for mobile conversations and data within the entire building complex, STF Tele Consult conducted a coverage and quality survey. The survey results and the client’s coverage targets formed the basis of a coverage concept involving a block diagram, a transmission layout and an antenna positioning plan, which were then incorporated into project management. As a result of the minutely planned implementation, the whole hospital building now boasts an excellent wireless coverage and capacity.
Project: Broadband rollout of a regional network operator
STF Tele Consult is planning and executing regional network operator NeckarCom‘s (www.neckarcom.de) broadband rollout in various districts and municipalities. In the state of Baden-Württemberg, more than 70 communities and municipalities have already been connected. The main challenge is to select the most economic fibre optic-based technology (FTTC, FTTH or FTTB).
Project: Broadband coverage for an industrial park
In order to connect the industrial park of the community of Senden in Westphalia (www.gemeinde-senden.de) to the broadband network, STF Tele Consult carried out a feasibility study and a market survey. STF’s engineers drew up a master plan for the broadband rollout, which then allowed for the initiation of a contract award procedure. For the duration of the project, STF was responsible for infrastructure planning, the supervision of construction and quality assurance of the broadband rollout. A prime concern during the project was – and still is – keeping the risks to the community, as a passive network operator, to a minimum. We succeeded: the companies in the industrial park now enjoy fast internet access.
Project: Project management in fixed network coordination
To ensure that E-Plus (www.eplus.de) meets all its rollout targets in the fixed network segment, STF Tele Consult is responsible for prioritising and coordinating all related activities. STF’s specialists are an interface to external partners, suppliers and E-Plus network planning and take care of the overall coordination of all parties involved.
Project: Introduction of energy-management system
Maschinenbau Lienenbrügger (lidu.de) has been a contract manufacturer for high-quality engineering solutions for over 70 years. At this long-established company, STF Energy introduced an ISO 50001-certified energy management system while production was ongoing. The client‘s priority was to reduce operating costs. Based on extensive metrological inspections and an analysis of the potential tax savings, STF Energy developed an energy-measurement concept.
Project: Introduction of an energy-management system
As a player in the metal processing industry, Härterei Reese (haerterei.com) is a particularly energy-intensive company. STF Energy developed an ISO 50001-certified energy-management system for Reese to help it improve its energy efficiency and lower its energy costs. In order to develop appropriate cost saving measures, we had to create complete transparency in all areas of the company’s energy consumption and use. In view of the complex processing procedures, the analysis was particularly challenging. Thanks to the implemented efficiency measures, the company’s energy targets were met.
Project: Energy-efficiency analysis for a Stadtwerke client
Stadtwerke Düsseldorf (swd-ag.de) is the largest energy provider and energy-service provider in the Düsseldorf region. STF Energy conducted an energy-efficiency analysis for an important client on behalf of Stadtwerke Düsseldorf. The analysis involved an inspection of all relevant equipment and an evaluation in terms of energy consumption. This allowed us to give the client a greater insight into its energy usage.
Project: Introduction of an energy-management system
Rhein-Ruhr-Malz GmbH (schillmalz.com) contracted STF Energy to implement an energy-management system in order to significantly reduce its energy costs for several locations. We conducted comprehensive measurements and drew up an action plan. The consumption analysis of the malting plant proved particularly challenging. The objective was to make the drying process as transparent as possible in terms of energy consumption and usage. Our STF experts successfully implemented an ISO 50001-certified energy-management system, and the subsequent exemption from the EEG levy was particularly appreciated by the client.
Project: Specialist planning of technical building equipment for new facility at Elspermann Großhandels GmbH & Co. KG
The Pietsch Group (www.pietsch.de) is one of Germany’s leading wholesalers in sanitary, heating and air-conditioning technology with over 50 locations nationwide. STF Energy assisted Elspermann Großhandels GmbH & Co. KG, a Pietsch Group subsidiary, with taking advantage of the full energy savings potential at its new building in Bochum. STF carried out the specialist planning for the heating, plumbing, ventilation and air conditioning. With the development of a comprehensive energy concept including an air source heat pump (Monovalent), the project was successfully completed with an EU GreenBuilding-programme certification.
Project: Specialist planning of technical building equipment for construction of the “Fressnapf-Akademie” building
STF Energy assisted Fressnapf, Europe’s largest retail chain for animal food, with its new “Fressnapf-Akademie” building. During planning, STF experts were instructed to take the heating, plumbing, ventilation and air conditioning into account as extensively as possible. STF Energy drew up a comprehensive energy concept taking into account the statutory requirements. Gas-fired heat pumps for heating and cooling to ensure controlled temperature and thermostatically controlled air inlets were integrated into the building. With the help of STF Energy, Fressnapf now boasts a new, modern and energy-efficient Fressnapf academy.
Project: Development, calculation and implementation of a heating facility for the historical Surenburg castle of in Riesenbeck
On behalf of KERKHOFF, STF Energy provided the concept, cost calculation and implementation for a heating system at Surenburg castle in Riesenbeck. The objective was to achieve the client’s energy-efficiency requirements while taking into account the high security standards as well as the specifications for historic landmarks. In addition, the STF planners had to consider the different energy users, such as the castle, the hotel and the swimming pool. With the help of STF Energy, the castle was successfully equipped with a highly energy-efficient and flexible heating system.
Project: New “Exerzierhalle”: New residential construction with 69 housing units with integrated underground garage for 169 parking spaces
