About ISP
ISP Ingenieurgesellschaft für Stahlbauplanung mbH is an engineering office based in Gelsenkirchen that specializes in structural design for steel construction. Founded in 1981 by 20 former employees of the steel construction department of the Denzinger Group, the company has been providing engineering services for over 35 years, from project design through structural design and static calculations to workshop drawings. Its service portfolio includes frame analyses as well as detail and connection statics for steel, timber and solid construction, seismic verifications, vibration studies, buoyancy verifications for tanks, feasibility studies, construction in existing structures, and the preparation of bills of materials and NC data. All design work is carried out entirely in 2D and 3D CAD technology, including TEKLA Structures, FrameWorks, Speedikon, AutoCAD and Microstation. Customers come from industries such as chemical plant construction, power plant construction, steelworks, coking plants, cement works, mechanical and plant engineering, conveying technology, and sports and assembly buildings. The project-dependent steel tonnage of the designed structures ranges from 1 t to 5,000 t and more; the office employs up to 20 engineers and technicians and trains technical system planners in the field of steel construction.
