Optimization of Projects and Design Reviews

The optimization of construction procedures, construction costs and operating expenses are a significant aspect of our work. Thanks to our decades of experience in the development of "special proposals" within the HOCHTIEF acquisition projects, along with countless design and engineering tasks in close cooperation with the construction sites, we draw on an extensive knowledge and understanding of construction projects that we can enhance your projects with. Naturally, we are also experienced in the checking of other aspects such as quality, feasibility and conformity with standards. 

BIM based Design

Due to our many years of activity in the energy and industry sector, we are extremely familiar with 3D design. About 30 years ago, we started working with object-oriented CAD and developed the UniCAD program system up to market maturity. Today we are able to provide our design services as BIM based with all common CAD software products. All our engineering design services - architecture, structural design and technical building services – are BIM-based. Our employees are not only proficient in the software used; we are also experienced in integrated design from other involved parties and are practiced in dealing with BIM regulations, such as AIA and BAP.

In the energy and industry sectors, the alignment of the structure with the plant and process equipment, by means of exchanging models, is a standard procedure for us. Upon customer's request, we also model the components of the plant and process equipment therefore creating the overall model.

Energy / Power

The entire team in the energy / power project sector has a comprehensive know-how in the structural engineering design of power generation plants. The field of activity of energy / power includes design services for the new construction of nuclear facilities, such as storage and logistics buildings for radioactive waste, the maintenance and retrofitting measures of existing plants and the structured dismantling of nuclear power plants. For each activity, the specific and specialized technical needs of plant and process equipment are of focal importance.

The decommissioning and dismantling team within this sector is active at almost all nuclear power plant sites in Germany and carries out the design tasks for the decommissioning and dismantling from shutdown to "greenfield". In doing so, this group provides comprehensive structural engineering services for deconstruction, dismantling, packaging, transport and logistics as well as for occupational safety and fire protection. In addition, our engineers also draw on extensive expert and specialist knowledge in the field of dismantling the actual plant. 

Following many years of experience in structural engineering design for the construction of new coal-fired power plants, combined cycle power plants and waste incineration plants, a new business segment was also developed in light of the German energy turnaround regarding the design of on-shore converter stations. In close cooperation with the client and the plant designer, and as part of the international design team, we provide comprehensive constructional design services for the various trades, through the draft, approval and implementation design phases up to the preparation of the BoQs and specifications. A vital component in the process is the use of BIM for the design, coordination and quality assurance. In addition to the preparation of the ready-for-construction drawings, the parameters for future use and maintenance are also addressed.

For offshore wind farms in the North and Baltic Seas, we provide design services for special components of the wind turbine foundations, we advise clients on manufacturing issues and we coordinate interfaces with manufacturers. Our experts are familiar with the relevant regulations; they prepare quality control plans and carry out monitoring at the manufacturers premises.
