Historic Buildings

As well has heavy foundation and retaining wall projects, we are known for the sensitive and delicate work of underpinning, renovation and upgrading of historical or sensitive buildings such as Chijmes or the National Art Gallery.

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

As 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.
