FERROBETON is the member of the CRH Group and the middle-east european center of CRH Structural

Ferrobeton Zrt. ’s fields of action Design: Construction plan, shopdrawings, 3D modelling, statical calculations Production: Structural products, railway elements, housing, road elements, electric poles Transport: By road or railways Installation:

-Possible to use higher quality of materials like C60/75 or higher -Controlled and monitored production, consistant quality -Independent from weather conditions -More precise production of reinforcement and concrete shape -Can be pre-scheduled for weeks, flexible in ordering Basic about prefabricating concrete Advantages Disdvantages -Sometimes difficult to transport to site -Shape is often limited by the formwork capacity -Creating load-bearing joints are complicated and expensive -Unit cost is higher Summary and worth to use Recommended to use in complex structures where lots of same elements are repeated Recommended to use to reduce in-situ concrete needs of large projects Recommended to use to decrease construction time

GREEN HOUSE Office building, Budapest Conditions to be known: -The erection time was scheduled to winter time -The construction site was narrow, the location is in the middle of the Capital -Only tower cranes were possible to use -3 weeks was given to complete a floor -The span were between 4,50 and 13,2m -Only a few bracing cores were possible -There are 3 levels for parking in the cellar as monolitic -There are 7 levels up for offices done as precast SPECIFICATIONS: -7 levels of precast flooring -Octagonal shaped columns -Delta-beam for floor support -No column in one corner Story: In Hungary almost all the office buildings are usually built with monolitic concrete structure sometimes combined with masonry. SKANSKA, a nord-european company insisted on that the structure has to be made by precast concrete elements to help FERROBETON completing this project.
