Langdon & Seah is a leading construction consultancy firm in Asia operating independently in 13 countries from 39 offices and a staff resources of nearly 3,000.

In April 2012, Langdon & Seah merged with Arcadis, an international consultancy, design, engineering and management services company.


Langdon & Seah has its roots traced to a successful Quantity Surveying practice in the United Kingdom of Horace W Langdon & Every dating 1919 which had bought over the Singaporean set-up of Waters & Watson in 1936, to form "Horace W Langdon & Every incorporating Waters & Watson".

The advent of war in Europe (1939) and South East Asia (1941) saw a severe setback in operations but the Singapore office remained open up manned by a skeleton staff headed by Seah Mong Hee before the island was finally occupied by the invading Japanese troops in January 1942.

Following the Japanese surrender in 1945, original partner Eric Watson restarted the firm in early 1946 and soon operation expanded with branches in Kuala Lumpur (1947) and Hong Kong (1949), encouraged by extensive post-war reconstruction work in the region.

In 1949, Seah was made a Partner and later Senior Partner in 1956 prompting a name change in the firm to Langdon & Every (Far East).

The firm continued it growth in South East Asia and by 1969, the words "Far East" were dropped to reflect the firm's expansion beyond the region and the practice became "Langdon Every & Seah".

In 1988, Langdon & Every in the United Kingdom and the Gulf countries amalgamated with Davis, Belfield & Everest (a firm formed in 1931 by Owen Davis who was joined in 1935 by John Belfield and in 1944 by Bobbie Everest) to become Davis Langdon & Everest. Following the swapping of shares, “Langdon, Every& Seah” thus became “Davis Langdon & Seah”. Recognizing the advantage of a global partnership, Davis Langdon (operating in Europe, Middle East, the United States of America, Africa, Australia and New Zealand) and Davis Langdon & Seah, established Davis, Langdon & Seah International which enabled the independently operated practices to tap on each other resources and experience.

In 2010, Davis Langdon was acquired by Aecom and with the expiry of the Swiss Verein in June 2012 for the global collaboration under DLSI, Davis Langdon & Seah reverts to Langdon & Seah.


The group offers a host of construction consultancy services including the core services of cost management and quantity surveying, cost engineering, project management and monitoring, management consultancy, due diligence, research studies, legal support, insurance valuations, sustainable construction and capital tax allowances.

The group’s experience is extensive across all segments in the construction sector from infrastructure works, retail, residential, industrial and commercial, as well as specialists work in the oil and gas industry.
