Grontmij designs winning CrommeLijn consortium tender for Spoorzone Delft

Up until 2016, Grontmij and the contractor consortium CrommeLijn will cooperate on the project Spoorzone (railway area) Delft, commissioned by railway infrastructure manager ProRail (in collaboration with the municipality of Delft). Grontmij is drawing up the designs for doubling the current track, the 2.3 km long train tunnel, the underground station, a car park and the organisation of public space. The CrommeLijn consortium is responsible for the realisation of the designs, schedules and budget.

The current railway track in Delft runs over a flyover and an earth ramp. It  is very intensively used by both passenger and goods trains. This causes a lot of noise and vibrations in the surrounding area. Additionally, the current flyover forms a visual barrier in the historic and tourist city of Delft. In short, the need for extending the railway and improving the situation around Delft has become increasingly urgent over the past decades.

“Building in a city, particularly in the busy centre of the old fortified town of Delft, sets very high demands for the design, construction methods, phasing, diversions and communication with the environment. We are proud to have provided the winning design for this complex project and to have supported the drafting of the contract,” according to Gert Dral, member of the Executive Board of Grontmij. “The assignment fits within our activities and is in perfect keeping with our ambitions and competencies in the area of urban development. We are also involved in comparable integrated inner urban projects such as the project A2 Maastricht, The Hague Central Station public transport terminal, the urban railway in Frankfurt, the Aarhus harbour project in Denmark and the Oosterweel connection in Antwerp.”

The Spoorzone Delft project has been set up as a design & construct contract and is according to the innovative Systems Engineering process, which means that the right balance between economic results, social interests and the environment is investigated for every step taken. Sustainability and a minimum of inconvenience are basic principles.

The assignment means a turnover of approx. EUR 13.5 million for Grontmij.

SHARON technology now also used in Paris

One of the wastewater treatment sites of Paris, the one in Seine-Grésillon, is to apply the innovative, cost-effective SHARON technology for its wastewater treatment.

SHARON (Single reactor system for High activity Ammonia Removal Over Nitrite) is a purification process patented by Grontmij, which allows nitrogen to be removed from waste water in a most efficient manner.
SHARON is different from other waste water treatment processes in that it includes no manner of sludge collection and/or separation whatsoever.

Having designed and developed no less than six SHARON installations in the Netherlands over the past years, Grontmij has recently been Commissioned for the design, engineering and realisation management of waste water treatment on the basis of the SHARON technology in New York, Geneva, Manchester and Whitlingham. And this ‘success story’ now also includes Paris.

The recently acquired assignments for SHARON installations have a completion time of several years (some run through to 2015) and will yield a turnover of several million Euros for Grontmij.
