Van Hattum en Blankevoort

Van Hattum en Blankevoort is a Dutch infrastructure construction company with roots going back to the early nineteenth century. Its predecessor activities began in 1831, when Arie van Hattum of Sliedrecht signed a five-year contract for maintenance of river groynes in the Merwede and Lek rivers. Ten years later, Cornelis Blankevoort established himself as a contractor in Monnickendam. The two contracting firms first cooperated around 1900 and from 1910 carried out all work jointly. In 1950, Van Hattum en Blankevoort NV was formally established, and in 1968 it obtained a stock exchange listing. Through a series of mergers it became part of larger Dutch construction groups: in 1971 the Stevin Groep was formed by merger, and in 1978, through combination with the Koninklijke Adriaan Volker Groep, Koninklijke Volker Stevin (KVS) was created. Further expansion led in 1997 to a merger with Kondor Wessels into the Koninklijke Volker Wessels Stevin group. Despite all these mergers, the name Van Hattum en Blankevoort survived as the name of one of the operating companies. The company has been active in the market for larger infrastructural projects since its founding in the nineteenth century. It was involved in practically all major works in the Netherlands, including the Zuiderzee Works in the 1930s and the Delta Works after the 1953 flood disaster. Worldwide, the company participated in the construction of large port and canal projects, such as the Panama Canal. Its project list includes the Blauwbrug (1883), the Zeelandbrug (1963–1965), the John F. Kennedy Bridge (1967), the Benelux Tunnel (1967), bridges in the Bijlmermeer (1968), the Bijlmerdreef metro bridge (1971–1975), viaducts at Rottepolderplein (1971–1974), the Kiltunnel (1974–1977), the Oosterscheldekering (1976–1986), the Zeeburgertunnel (1984–1989), the Maeslantkering and Hartelkering (1991–1997), the Museumplein parking garage (1999), the Hollandsch Diep bridge (2000–2004), the Sijtwendetunnel (2003), the Hoge Brug in Maastricht (2003), the Mosae Forum parking garage (2002–2006), the Hubertustunnel (2004–2008), the Ramspolbrug (2009–2010), the Westrandweg (2009–2012), the Máximakanaal (2010–2014), the second Julianasluis (2011–2014) and the A4 Delft-Schiedam (2012–2015). From 1890 the company was based in Beverwijk. In 1993 it moved its head office to Woerden, and in 2017 it relocated to its current headquarters in Vianen, in the same building as VolkerInfra. Today, Van Hattum en Blankevoort presents itself under the slogan "Bouwen met impact" (Building with impact), focusing on water safety, water quality, mobility, energy supply and inner-city construction. Its official website describes work on water safety (keeping feet dry), inner-city building for liveable residential environments, mobility (keeping the Netherlands accessible), energy (working on energy security) and water quality (ensuring clean drinking water). The company states that for nearly two centuries it has worked on ingenious solutions for climate change, population growth and urbanisation, realising concrete and sustainable solutions through smart civil works. Its projects, large and small, new-build and renovation, are said to have tangible social impact, from the imposing Oosterscheldekering to the advanced Echten water treatment plant and from the historic Binnenhof to the contemporary IJboulevard. The company emphasises cooperation with employees, partners and customers to build a liveable Netherlands, working sustainably, safely and with integrity.

The history of Van Hattum en Blankevoort begins with two separate nineteenth-century contracting businesses. In 1831, Arie van Hattum from Sliedrecht signed a contract for five years of maintenance on river groynes in the Merwede and Lek rivers. Ten years later, in 1841, Cornelis Blankevoort established himself as a contractor in Monnickendam. The two firms first worked together around 1900, and from 1910 they carried out all their work jointly. In 1950, the combined enterprise was formally incorporated as Van Hattum en Blankevoort NV. The company obtained a stock exchange listing in 1968. In 1971, a merger created the Stevin Groep. In 1978, a further combination with the Koninklijke Adriaan Volker Groep produced Koninklijke Volker Stevin (KVS). Continued expansion led in 1997 to a merger with Kondor Wessels, forming the Koninklijke Volker Wessels Stevin group. Throughout these mergers, the name Van Hattum en Blankevoort was retained as the name of one of the group's operating companies (werkmaatschappijen). The company has been active in the market for larger infrastructural projects since its nineteenth-century origins. It was involved in practically all major works in the Netherlands, including the Zuiderzee Works in the 1930s and the Delta Works following the 1953 flood disaster. Internationally, it participated in the construction of large port and canal projects, such as the Panama Canal. Its long project record includes the Blauwbrug (1883), the Zeelandbrug (1963–1965), the John F. Kennedy Bridge (1967), the Beneluxtunnel (1967), bridges in the Bijlmermeer (1968), the Bijlmerdreef metro bridge (1971–1975), viaducts at Rottepolderplein (1971–1974), the Kiltunnel (1974–1977), the Oosterscheldekering (1976–1986), the Zeeburgertunnel (1984–1989), the Maeslantkering and Hartelkering (1991–1997), the Museumplein parking garage (1999), the Hollandsch Diep bridge (2000–2004), the Sijtwendetunnel (2003), the Hoge Brug in Maastricht (2003), the Mosae Forum parking garage (2002–2006), the Hubertustunnel (2004–2008), the Ramspolbrug (2009–2010), the Westrandweg (2009–2012), the Máximakanaal (2010–2014), the second Julianasluis (2011–2014) and the A4 Delft-Schiedam (2012–2015). In terms of location, the company was based in Beverwijk from 1890. In 1993 it moved its head office to Woerden. In 2017 it relocated to its current headquarters in Vianen, in the same building as VolkerInfra. Today, as a subsidiary of Koninklijke Volker Wessels Stevin, it continues to work on water safety, water quality, mobility, energy and inner-city construction projects, presenting its work under the slogan "Bouwen met impact".
