Hasselmann: Paving the way.

Platform construction requires expertise in both conventional construction methods and modular system solutions in order to ensure the satisfaction of rail passengers through attractive design with contemporary accents and innovative implementation services. The impression made by stations and platforms is seen as essential for pleasant rail travel. All services involved, from construction site planning to final implementation, are provided by the company's own highly trained and experienced specialists. This avoids difficulties at the interfaces between different trades and ensures consistently high quality with minimum construction time. > OVERVIEW OF SERVICES New construction, repair and modernization of platforms, staircases, lighting systems, public address systems, floor coverings (paving, bituminous coverings) and staircases New construction, repair and modernization of platforms, staircases, lighting systems, public address systems, floor coverings (paving, bituminous coverings) and staircases Installation of wayfinding systems and platform equipment (showcases, weather shelters, platform roofs, benches, litter garbage cans, etc.) Corrosion protection work, cleaning work and coating work - Retaining walls and access routes, ramps

Hasselmann GmbH's civil engineering services include all conventional civil engineering services required for the conversion or new construction of track systems. Track civil engineering forms the basis for the subsequent track construction services. Experienced and continuously trained skilled workers carry out these services, supported by state-of-the-art and constantly updated machinery. OVERVIEW OF SERVICES Dismantling of old facilities Soil replacement, soil improvement/soil stabilization Installation and renewal of subgrade and frost protection layers, laying and tamping gravel New construction, repair and modernization of drainage systems Longitudinal track shoring and ballast maintenance Foundations for auxiliary track bridges

The complete construction services for underground cable construction in the railroad sector are also among Hasselmann GmbH's areas of expertise. Here, solid craftsmanship techniques are combined with the use of state-of-the-art technologies. In this sector, all preparatory and installation work is also carried out by our own staff, who are constantly undergoing further training. - OVERVIEW OF SERVICES - All associated civil engineering work - New construction, repair and modernization of cable trough systems, underground pipe routes, cable shafts and open and controlled track crossings - Cable pulling and laying work - Foundation work and installation of switch houses and signals

Hasselmann GmbH also offers a wide range of services in the field of electrical engineering in railroad construction, which our clients have relied on for years and trust that our expertise guarantees a high level of quality. OVERVIEW OF ELECTRICAL ENGINEERING SERVICES Supply and installation of electrotechnical systems for the power supply and lighting of DB InfraGO AG and DB Energie GmbH transportation stations, e.g. 16.7Hz/50Hz point heating systems Track field lighting Platform lighting<br> Earthing systems Hot rotor detection systems NS/MS Cable systems for power supply MS stations New construction, repair and modernization of public address systems

Hasselmann GmbH has its own department for the planning, manufacture and assembly of special steel constructions. This enables the efficient and professional realization of contract work involving complex steel construction services. OVERVIEW OF SERVICES SIGNAL MASTS, SIGNAL BRACKETS, SIGNAL BRIDGES, LIGHTING MASTS Planning, production and assembly including foundations for lighting poles Planning, production and assembly of standard and special constructions (signal booms, signal bridges, signal masts, signal umbrella brackets including special fastenings for platform roofs, walls, etc.) Existing certifications: Conformity of factory production control (production of load-bearing components up to EXC3 according to EN1090-2) Welding certificate in accordance with 1090-2.00547.GSIDu.2021.001 DIN EN ISO 9001:2015

Bridges and culverts are important components of the infrastructure in road, rail and path networks. Maintaining and expanding the performance of an economic area requires constant maintenance as well as the planning and implementation of necessary extensions to such traffic arteries. As a result, there is also a need for the construction or renovation of bridges and culverts. Hasselmann GmbH carries out such projects itself while maintaining ongoing traffic. The engineering structures created or refurbished in this way impress with their individual design, state-of-the-art construction and harmonious integration into the respective surroundings. - OVERVIEW OF SERVICES - New construction, modernization and renovation of bridges in reinforced concrete construction - Formwork, reinforcement work and concreting - Associated steel construction (e.g. fall protection, handrails, extinguishing water pipes, etc.) and civil engineering (e.g. construction of excavation pits, shoring, etc.)

Civil engineering structures also include stairs, elevator shafts and ramps for connecting underpasses. Hasselmann GmbH's range of services includes the planning and implementation of such partial construction measures as well as the handicapped-accessible expansion of transportation stations. OVERVIEW OF SERVICES New construction and modernization of elevator shafts, staircases, supporting structures and disabled-accessible ramps Formwork, reinforcement work and concreting Associated civil engineering (e.g. construction of excavation pits, shoring, etc.) and steel construction (e.g. railings, handrails, etc.) Execution of surfacing work (e.g. paving, bituminous surfacing, etc.) Installation of components of the wayfinding system

Passenger underpasses are required in many stations. In conjunction with stairways, ramps or elevator systems, access routes are created to the individual platforms, which can then be safely accessed independently of rail operations. Pedestrian underpasses are particularly suitable as underground connecting routes from streets and squares. OVERVIEW OF SERVICES New construction and modernization of elevator shafts, staircases, supporting structures and ramps for the disabled Formwork, reinforcement work and concreting Associated civil engineering (e.g. construction of excavation pits, shoring, etc.) and steel construction (e.g. railings, handrails, etc.) Execution of surfacing work (e.g. paving, bituminous surfacing, etc.) Installation of components of the wayfinding system
