First pour-through with our Schwing SPB35 placing boom, made possible by a piece of problem solving we are genuinely proud of.
A separate placing boom normally anchors to the building it is pouring: ballasted to the structure, climbing with it floor by floor. At Forster, a late design change took that approach off the table after the job was already planned. The boom still had to go up, and the pour dates did not move.
Working with the project engineers, our team developed a freestanding counterweight ballast frame: a self-supporting base that carries the SPB35 without loading the structure at all. Checked before anything stood on it, the frame let the job proceed safely without redesigning the building around our equipment.
May 2026 saw the first pour-through, with the SPB35 working beside the tower crane exactly as planned. The lesson is one our clients lean on: when the neat answer disappears, a fleet that engineers its own solutions keeps your program alive.
A separate placing boom on the deck, fed by a high pressure pump at street level, is the system behind every multi-storey pour we do. Forster shows the other thing that matters: the engineering judgement around the equipment. More on the system, and where it earns its keep, on the high rise page.
Volume, date, and what the access looks like. We will come back with the right unit for the job, and if the site is tricky we will look at it first.
