PARTNERS

ERNST² has worked on large-scale projects for new buildings and general refurbishments throughout Germany. It has successfully completed projects in a wide variety of sectors, such as health, research and teaching, industry, administration, housing as well as specialized buildings.

Our company is well versed in the planning and execution of conversions and refurbishments of large building complexes, which are fitted with various technical installations. Many projects were performed while the buildings were still in use.

The Klebl Group is a leading medium-sized business in the German construction sector, which manufactures and sells precast concrete elements. Klebl manufactures the precast concrete elements at six different sites within Germany. With a 1,400-strong workforce, the company is a specialist in turnkey construction for medium-sized and large construction projects.

Role in project
Klebl was assigned as the general contractor for turnkey building elements for the buildings 3.1, 3.4, 4 and 5 at the new site.
The prefabricated reinforced concrete elements are manufactured at three of our six production sites, but mainly at the Gönnern site in the state of Hesse.
Klebl is confident that all the precast elements will be delivered according to schedule.

Keller Grundbau GmbH belongs to the Keller Group plc, which is listed on the London stock exchange. The company specializes in geotechnical engineering.
Our services include ground surveying, ground improvement and excavation work. We operate in eight different market segments combining methods and products to always find the best geotechnical solution.
In many cases, the best and most cost-efficient solution involve a combination of several ground-improvement techniques depending on the site conditions.

Role in project
SAMSON contracted us for the construction of 2,500 CFA piles to create deep foundations for the buildings at the new SAMSON site in Offenbach. Continuous flight auger (CFA) piles are constructed by rotating a hollow-stem continuous-flight auger into the soil to a designated depth. Concrete or grout is pumped through the hollow stem to fill the cylindrical cavity created as the auger is slowly removed. The reinforcement cage is placed through the freshly placed concrete. These piles transfer loads from the structure (e.g. hall supports) to the ground, which help support it.
The contract work also involves geotechnical calculations, survey work, checking for unexploded bombs and the installation of steel sheet piling.

The demolition company Zeller was founded over 70 years ago. Our family-run business now in its second generation has many years of experience in demolition projects. We pride ourselves on our reliable, on-time performance.

Demolition: Robert Zeller GmbH & Co. KG offers all relevant services from one single source, regardless of whether a single house or a large industrial complex is to be demolished. The company can provide a complete package comprising all services.

Earthworks: Thanks to its state-of-the-art construction machinery and experienced staff, we can reliably perform all types of earth-moving operations.

Controlled blasting: Controlled blasting is a technique often used during demolition operations. Depending on the structure being demolished and the on-site conditions, controlled blasting is often the safest, most economic and environmentally sound method of demolition.

Werner Hartwig GmbH is an engineering company founded in 1962. It specializes in wastewater management and construction of roads and special structures. It has many years of experience in all service phases according to the official German regulations governing the fees for services by architects and engineers (abbreviated to HOAI in German). It offers consultation services in all the service phases. It also specializes in survey work and coordination services for health and safety measures at construction sites (abbreviated to SiGeKo in German). Numerous private investors as well as more than 150 public local authorities figure among its customers. This opens up the way for synergies and has a beneficial effect on future projects.

The company is run across the generations by two engineers Björn Hartwig and Robert Pücko. They are members of the Chambers of Engineers in the German federal states of Hesse and Rheinland-Palatinate as well as qualified engineering consultants. A team of 25 professionals work together on the engineering projects. The company belongs to the Chambers of Engineers of Hesse and Rheinland-Palatinate, DWA (German Association for Water, Wastewater and Waste), DVGW (German Technical and Scientific Association for Gas and Water) and BWK (German Association of Engineers for Water Management, Waste Management and Land Improvement). It is also registered as a pre-qualified company by the German chamber of commerce and industry.

Role in project
Werner Hartwig GmbH is responsible for the planning, tendering and coordination of civil engineering and road construction activities for the MainChange project.
These activities include the laying of around 3,000 m surface and sewage water pipelines and the construction of three rainwater retention basins with upstream pre-treatment installations. The rainwater retention basins with an overall storage volume of around 4,500 m³ are designed to hold back rainwater before it is pumped into the public wastewater network. Furthermore, planning and coordination of the underground construction work for the utilities pipelines (gas, water, district heating, hydrogen, electricity etc.) is underway.
An area of around 37,000 m² for roads, paths and parking lots is also being planned. These planning activities involve the efficient layout of on-site traffic and the optimal connection to the public road network. The goal is to optimize site logistic operations and maximize the site accessibility for staff and visitors.

The fundamental transformation of the work environment starts with office space. As our past experience clearly demonstrates, a new era of the workplace can only succeed in offices designed specifically to meet the latest requirements.
We are contributing to this transformation by modernizing the workplace. We create spaces, which positively influence the motivation, productivity and well-being of the workforce.
For over 40 years, we offer consultation and planning services to take office design to the next level.
The aim of our cooperation is to match the building structure, installations and office design to employees' needs.
As part of a workspace analytics process in close cooperation with SAMSON, we performed a survey to find out staff requirements. The survey results are used as a basis to create a new work environment at the new SAMSON site.
