Bachy Soletanche Singapore arrived in Singapore in the 1970’s and was incorporated in 1982.

Bachy Soletanche Singapore (BSS) is a subsidiary of the world’s foremost geotechnical specialist engineering contractor, Soletanche Bachy.

Involved in some of the country’s most outstanding infrastructure and iconic buildings, we have played a significant role to build the foundations of the Smart and Green city that Singapore is globally-recognised for today.


Our Vision

Our Vision is to be the preferred Geotechnical Contractor to Clients or Main Contractors, working as a partner or a specialist subcontractor.

We strive to provide the highest value solutions to our Clients, bringing leading innovation and global competence to the local Singapore market. As a performance driven company, within a culture of safety, innovation and excellence.

Historic Building


As well as heavy foundation and retaining wall projects, we are known for the historical buildings such as Chijmes or the National Gallery Singapore.

For the National Gallery, the challenge was to convert the former City Hall and Supreme Court, both National Heritage Buildings, into an iconic National Gallery Singapore.

As a specialist subcontractor, we successfully created the retaining walls in and around the historic buildings to construct up to three levels of basements in a very challenging environment with very low headroom and significant space constraints working in the middle of historic Singapore with significant traffic management and geological challenges.
