CUT IT OUT IN SECTIONS. PROTECT THE REST.
A bridge or wharf doesn't come down the way a building does. The structure is mass-reinforced, it usually stands over a live road, rail corridor or waterway, and half the job is protecting what stays — the adjacent span, the services on the deck, the traffic underneath. The safest way to demolish heavy infrastructure is to cut it into engineered sections and lift them out.
That's the method we're built for. Our Hilti DSW 1510-CA diamond wire saw cuts mass-reinforced concrete, steel and stone to unlimited depth in any direction — horizontally through a pier, vertically through a headstock, at an angle through a deck, even underwater. Every cut is planned to the crane's capacity, so piers, headstocks and deck segments come away as clean, liftable pieces with minimal vibration transferred into the remaining structure.
Where breaking is the better tool — abutments, approach slabs, culverts and upstands — the remote-controlled Husqvarna DXR 305 demolition robot works beside live traffic and rail with the operator outside the exclusion zone. Together the two methods cover the full scope: cut, break, lift, clear.
Every infrastructure job runs on engineered methodology — cut sequencing, temporary works, lift plans and full SWMS — the same discipline behind our broader complex demolition service. Night works and possession windows are standard. See what drives wire sawing costs, or request a quote with your drawings.
