Bilfinger’s phase 2 Söğüt Gold Mine expansion: construction and tie-in notes for engineers

30 Second Briefing
Bilfinger has secured a major contract from Gübretaş Maden Yatirimlari A.S. to deliver phase 2 expansion works at the Söğüt Gold Mine in Bilecik, Türkiye, using its newly acquired subsidiary Teknokon Endüstri Tesisleri İnşaat ve Montaj A.S. Up to 650 personnel will execute the full mechanical expansion scope, signalling a substantial brownfield construction effort on an operating gold asset. The scale of the workforce points to intensive plant installation and integration, with implications for construction sequencing, contractor coordination, and maintaining production during tie-ins.
Technical Brief
- Scope explicitly includes full mechanical works, implying extensive process plant, piping and equipment installation.
- Industrial services framing suggests Bilfinger will also manage construction interfaces with existing utilities and services.
- Large mechanical expansion on an operating gold plant will require detailed shutdown planning and staged tie-ins.
- Similar brownfield gold expansions often see mechanical scope on the critical path for ramp-up schedules.
Our Take
Bilfinger’s role at Söğüt adds to its recent visibility in our database on large industrial builds, including the Johnson Matthey hydrogen gigafactory in the UK, signalling that its process-plant skillset is being applied across both energy-transition and precious metals assets.
A 650-strong phase 2 construction workforce at a single gold asset in Bilecik suggests a build-out scale more typical of mid-tier greenfield plants in our Mining coverage, implying notable temporary pressure on local labour, accommodation and logistics capacity in this part of Türkiye.
