Title: | Site facilities on contract SBT 3.1 / Die Bauinstallationen im Baulos SBT 3.1 |
Abstract: | On contract SBT3.1 of the Semmering Base Tunnel, the intermediate access point at Grautschenhof had to be relocated late in the tender design phase due to new geological findings. One consequence of this was the limited space available on the new construction site area. A number of complementary measures were considered by the client in the tender. Supplemented by innovative technical solutions from the SBT 3.1 Grautschenhof joint venture, it was possible to establish a functioning logistics system for four conventional excavations in the tightest of spaces. Für das Baulos SBT3.1 des Semmering-Basistunnels wurde aufgrund neuer geologischer Erkenntnisse spät in der Ausschreibungsplanungsphase eine Neusituierung des Zwischenangriffs Grautschenhof erforderlich. Eine Folge hiervon waren deutlich beengte Platzverhältnisse auf der neuen Baustelleneinrichtungsfläche. Daher hat der Bauherr eine Reihe von ergänzenden Maßnahmen in die Ausschreibung aufgenommen. Ergänzt durch innovative technische Lösungen der Arbeitsgemeinschaft SBT 3.1 Grautschenhof konnte so auf engstem Raum eine funktionierende Logistik für vier zeitgleich laufende konventionelle Vortriebe errichtet werden. |
