About the Engineering Office
Ingenieurbüro Lorenz GmbH was founded in 1990 in Rostock as an engineering office for steel structures. Its field of activity covers engineering services in the areas of hydraulic steel structures, movable bridges, special steel constructions and marine equipment. The structures handled include lock gates, gate and circular slide gates, weir flaps, stoplog panels and beams, bridge bearings and bridge drives for swing, bascule and sliding bridges, ferry flaps, steel bridges, masts, walkways as well as hatch covers and hull openings. Autodesk products (AutoCAD, Inventor) are used for design and drawing creation, and PCAE software is used for structural calculations; the conversion of CAD files into the Microstation format required by the waterways and shipping authorities is carried out in-house. The services cover all design phases including structural stability verifications, bills of quantities as well as draft, execution and manufacturing drawings; in addition, condition surveys with wall thickness and coating thickness measurements as well as fatigue strength and classification calculations are offered. Customers include, among others, waterways and shipping authorities, engineering offices as well as construction and steel construction companies.
