Pöyry, YIT and VR Track have signed an agreement with the City of Tampere for the implementation of the Tampere light rail project. The revised cost estimate for the implementation stage is EUR 238.8 million. The first phase of construction will commence in the first half of 2017 and is expected to last until 2021. During this phase, the new rail line will extend 15 kilometers, from the city centre to Hervanta and to the Central Hospital, and a depot will be constructed in Hervanta. According to the plans, the second phase of construction will take place in 2021-2024. It will expand the rail network from the city centre to Lentävänniemi. The project will be implemented using the alliance model, with YIT, VR Track and Pöyry providing the service ordered by the City of Tampere. In the alliance model, the client, designers and contractors co-operate throughout the implementation. "The representatives of Tampere and the engineers and contractors of the light rail project have worked hard together for over a year to find the best solutions for the project. The implementation decision will realise this work for the benefit of Tampere, resulting in a smooth implementation of the project and a high quality light rail system. We at Pöyry are proud to support the strong development of the Tampere region," confirms Mikko Inkala, President of Pöyry's Infrastructure Design Unit. "Alliance partners' close cooperation and commitment to high objectives of the project from the very beginning have made it possible to implement the tramway. Construction of tramway will be visible in the streets of Tampere, but the implementation plan drawn up together in the development phase and a strongly connected Alliance team will create excellent conditions for the smooth implementation of the project," says Harri Lukkarinen, Managing Director of VR Track. "YIT's revised strategy emphasises project development in growth centres and focuses increasingly on the involvement of partners. The collaborative alliance model adopted in the Tampere light rail project matches this objective very well. The project is significant in terms of size. It also plays an essential role in the development of the Tampere region, in which YIT wants to be closely involved," says Jouni Forsman, Head of YIT's Infra Services business division. The value of the order is undisclosed. The order will be recognised within the Regional Operations order stock in Q4/2016. Did you know?

Head regulator for irrigation canal networks is built at the head of each off-taking canal to admit and regulate the discharge into the off-taking canal from parent canal. IS 6531 : “Criteria for Design of Canal Head Regulator” specifies guidelines for design of head regulator for canal off-taking from river only and guidelines are valid for open channel type head regulator with raised crested entrance with gate over it. The provisions in IS 6531 are not valid for close conduit type or pipe type head regulator for canal off-taking from parent canal. Hydraulic theories of pipes and culverts available in codes and books can suitably be used for pipe type head regulator, considering governing hydraulic and field parameters. But no consolidated literature regarding the use of these theories for pipe type head regulator with the governing parameters is available in codes and books. Hence the designer has to deal with the help of empirical formula and his knowhow. The pipe type head regulator designed with limited theories may lead to failure of hydraulics, and may make the structure uneconomical. Integrated approach considering hydraulic and filed parameters depicted in the technical paper helps to choose precise diameter of pipe for hydraulically functional and economical head regulator for irrigation canal networks. © 2015 Central Board of Irrigation and Power.

The contact fatigue performance of two pairs of case carburised gears with either an as-ground or superfinished surface finish was studied. This comparison test was carried out using a back-to-back gear test rig. Test results showed that superfinished gears provided an enhanced contact fatigue resistance with only the development of minor scratches and light micropitting after running, while as-ground gears failed through a sequence of initial micropitting, progressive micropitting, macropitting and scuffing. © 2011 Trans Tech Publications.
