Strukton commissioned to renovate and build substations for Utrecht tram line

27 August 2014

Strukton Systems has been awarded a contract by Regiotram Utrecht to renovate four existing substations and construct a new substation for the Utrecht, Nieuwegein and IJsselstein rapid transit line (SUNIJ Line). The contract covers the design, construction, installation and testing of the newly-built substation and the adaptation, installation and testing of the new systems in the existing substations. Work at the various sites will start in September 2014, and the scheduled acceptance date is 1 October 2015. The project represents a total contract value of some € 5.5 million.

The contract was awarded on the basis of the Most Economically Advantageous Tender (MEAT) criterion, in which Strukton achieved the highest score. This means that the submitted price was not the only factor that played a decisive role in the contract’s awarding, but also the adopted approach, which will ensure that the project is realised in a manner that is safe, in accordance with the established quality requirements and with minimal nuisance to local residents and companies.

Four of the total of seven substations along the SUNIJ Line need to be adapted to modern requirements and wishes. The substations are used to transform a high voltage (10,000 volts) to a lower voltage, after which the power can be transmitted to the tram’s overhead line. In terms of structural engineering, the space in the substations needs to be reorganised by creating separate spaces for low voltage, high voltage, a separate space for the supplier (Stedin) and the necessary entrances to these spaces. In the case of the newly-built substation for the Nieuwegein tram depot, Strukton has been contracted to design and construct a new substation as well as the various systems for the substation building.

Utrecht rapid transit network

The high-speed tram line between Utrecht and Nieuwegein/IJsselstein – the SUNIJ Line – is part of the Utrecht rapid transport network, which connects the various areas in and around the city of Utrecht. On 1 December 2013, Strukton Rail started fulfilling the maintenance contract for this tram line, which has a minimum term of five years. The next step in the expansion of the tram network is the construction of the Uithof Line. On a regular week day, some 25,000 people presently take the bus to travel to and from the Uithof area. By 2020, the new tram connection to this area will transport over 45,000 passengers daily – almost double the number of people currently making use of public transport for this journey.
