First episode: from our establishment until World War II
In 1928 Tauw was established in the city of Haarlem as the Technical Consultancy of the Union of Water Boards in the Netherlands, as the Water Boards increasingly needed independent and technically high-quality advice in Water Board issues. Especially the transfer from steam-engined pumping stations to electrically engined pumping stations was the main driver. The three main divisions were: Civil Engineering, Electrical & Mechanical Engineering and Construction. Due to the construction of a new polder, the first branch office was established by the end of the thirties in the province of Groningen. The number of staff increased during this episode from 5 to 40.


Second episode: from WW II - 1954
During WWII activities were low, but after the war the large reconstruction programmes initiated a sharp growth in the activities of Tauw. From 1947 Tauw secured a lot of reconstruction orders for pumping stations. The scope of activities was expanded with geodetical services, based in Utrecht. In 1950 Tauw became involved in its first international projects in Canada. The large amount of work in the Dutch market after the big flood in 1953 created a strong focus on the Dutch market. All resources were needed for reconstruction work.


Third episode: from 1954 - 1967
In 1954 Tauw started its activities in environmental engineering: waste water engineering and laboratory facilities were added to the spectrum of Tauw’s activities. In addition to the opening  of a laboratory in The Hague, new project offices were installed in Steenbergen and Almelo.
Shortly after a second laboratory was opened in Haarlem. In 1955 the legal structure was changed: the partner structure was converted into a Ltd. In 1964 a new branch was opened in Lochem to improve our services towards our regional clients. During the sixties a two-year project was implemented in South Korea and Tauw became involved in more international projects around the globe.


Fourth episode: 1967 – 1980
In 1967 a subsidiary was established under the name of Infra Consult. As Tauw was working more and more for other clients than water boards, these projects were implemented under the flag of Infra Consult. In the international market, projects were carried out in the Caribbean, Africa and the Middle East. A large project in 1970 for the urban development of the city of Utrecht resulted in a branch office in Maarssen. In 1975 the branches in the eastern part of the Netherlands merged and the new headquarters consequently transferred from Haarlem to Deventer.
In addition there were three branches in Haarlem, Tilburg and Maarssen.


Fifth episode: 1980 – 1990
The Lekkerkerk case was the starting point of the legislation on contaminated land in the Netherlands.  From the start Tauw was also involved in projects related to soil contamination. This led to a sharp growth of our environmental activities during the eighties: the size of Tauw expanded over this decade from around 120 to 650 employees. New services were initiated in waste, air monitoring and environmental management. In 1985, Tauw bought its shares as held by the Union of Water Boards and brought the shares into the Foundation: ‘Stichting Aandelenbeheer Tauw’ (Tauw Share Management Foundation). In 1987 the employees were offered the opportunity to buy Tauw share certificates, a new phenomenon in the Netherlands! During the eighties Tauw became involved in projects from the industry as well as in international projects in Europe. We gave assistance to the Federal State of Baden Württemberg to develop their soil policies.


Sixth episode: 1990 – 1998
Tauw expanded during the nineties because of a large number of take-overs: the acquisitions of DSBV (1990, Rotterdam), De Haan Consult (1990, Nieuw Vennep), Nagtglas Versteeg (1991, Nieuwegein), Van Steenis (1995, Utrecht), Intron (1995, Sittard and Houten), Centrilab (1995, Soest), MABEG (1996, Utrecht, Assen and Eindhoven). Over the first half of the nineties, branches were established in Germany (1992), Belgium (1994) and France (1995). In 1995 Wadinko, a regional investment company, entered with 10% in the share capital of Tauw. Shortly after (1997) this participation was enlarged to 40%. In 1996 Tauw secured its first ISO 9001 certificate. In 1997 the activities of Nagtglas Versteeg were terminated by means of a management buy-out.


Seventh episode: 1998 – 2000
In 1998 the civil and environmental engineering activities of Tauw merged into a new organisation. A new strategy was developed, shifting from a financial holding with a division structure to a strategic holding with a country oriented structure and a strong focus on synergy. Integrated services in urban and rural development were the new basis for our services towards authorities. In addition Tauw enforced its activities in the (multinational) industry. Activities that did not fit in this new strategy, were terminated through the sale of Intron (1999) and Centrilab (2000). In the international market Tauw entered into cooperation with COWI (Denmark) and Enviros (UK) in the field of Environmental Due Diligence Assessments in 1999. This cooperation has since been expanded into a worldwide partner network.


Eighth episode: 2000 - date
By the start of the 21st century Tauw realised take-overs in Italy (EcoAppraisal, 2000 / 2001), Spain (Covitecma, 60%, 2003) and in 2004 entered into cooperation with Agrolab (Germany) in the field of laboratory developments. By the end of 2006 the laboratory activities were completely sold to Agrolab. In 2005 Van Steenis (geodetical services) was declared bankrupt and was continued as a self-supporting company with the assistance of Tauw. In the same year Tauw’s new strategy was developed: putting a strong focus on the European market by enforcing its international activities. That year the activities of LUBAG (Bavaria) were added to the German organisation, followed towards the beginning of 2007 by the take-over of Wohlfarth consultancy near Cologne. Tauw has increasingly been working for international client groups: the multinational industry, private equity and real estate sectors.
