Bachy Soletanche Singapore

What Bachy Soletanche Singapore does

Bachy Soletanche Singapore Pte Ltd is a specialist geotechnical and foundation engineering contractor that has delivered underground and structural works in Singapore since the mid-1970s. The company is a wholly-owned subsidiary of Soletanche Freyssinet (itself part of the VINCI group), positioning it within one of the world's largest geotechnical networks spanning approximately 60 countries and 80 subsidiaries. Its core capabilities include deep diaphragm walls (to 75m depth), tunnel boring (CR116 machine), pipe jacking, deep soil mixing, jet grouting, and barrette pile construction, supported by proprietary Hydrofraise® hydraulic cutting equipment with grippers and roller bits that enables low-vibration excavation adjacent to live MRT tunnels.

The business operates on a project-based, competitive-bid model serving Singapore government infrastructure programs — primarily the Land Transport Authority (LTA) for MRT stations, expressways and the North-South Corridor, with select commercial and residential foundation work. The company executes contracts either as lead general contractor for design-and-build packages or as a specialist subcontractor through joint ventures with major contractors including Penta Ocean, Gammon Construction, Taisei Corporation, CSCEC and Wai Fong Construction. Notable delivered projects include T303 Tanjong Rhu Station (TUCSS Project of the Year 2024), the NSC 105 tunnel diaphragm wall (8.37 million LTI-free hours), and ongoing work on P103 Riviera and CR116 Ang Mo Kio for the Cross Island Line.

Commercially, Bachy Soletanche Singapore generates revenue from professional-services construction contracts on a quote-based, bespoke basis — there are no public pricing tiers or recurring SaaS-style revenue. The customer base is concentrated almost entirely within Singapore government infrastructure, creating a pipeline-dependent revenue model tied to LTA's multi-decade capital program. The company's value proposition rests on its 45-plus year local track record, its safety record (multiple WSH SHARP Awards in 2023), its proprietary Hydrofraise® technology, and its ability to mobilize within the Soletanche Bachy Group's global equipment and engineering resources.
