Wildpoldsried/Munich/Vienna – The SYSTABUILD Soft­ware Group, a BU port­fo­lio company and leading Euro­pean plat­form for soft­ware solu­ti­ons in the cons­truc­tion and trades sectors, is acqui­ring a majo­rity stake in Network Dimen­si­ons GmbH, based in Vienna. Foun­ded in 1997, the company deve­lops MEGABAU, an ERP solu­tion for the cons­truc­tion indus­try, and is one of the estab­lished specia­lists in the commer­cial and opera­tio­nal manage­ment of cons­truc­tion compa­nies in German-spea­king countries. 

Network Dimen­si­ons comple­ments the SYSTABUILD Soft­ware Group’s ERP soft­ware port­fo­lio. MEGABAU combi­nes project manage­ment, resource plan­ning, and finan­cial manage­ment into a single solu­tion based on Micro­soft Dyna­mics 365 Busi­ness Central—tailored to the proces­ses of cons­truc­tion and indus­trial compa­nies, ranging from buil­ding cons­truc­tion and civil engi­nee­ring to wood, steel, and metal fabri­ca­tion, as well as buil­ding services, earthwork, as well as demo­li­tion and recy­cling.

He is over­see­ing the tran­si­tion as part of a struc­tu­red process within the execu­tive manage­ment team. Florian Thur­ner, previously mana­ging part­ner of the subsi­diary ND Projects GmbH in Villach, is joining as a co-part­­ner and mana­ging direc­tor and is reinves­t­ing his previous stake into the new structure.
