Opening new Horizons for liveable Cities
Finding eco- and climate-friendly infrastructure solutions for liveable cities, where space and financial resources are limited, poses huge challenges. If these are to be tackled effectively engineers need to think outside the box and explore new horizons.

Innovative Vinyl Sheet Piles protect Climate and Environment
Innovative sheet piles made of plasticizerfree polyvinyl chloride (PVC-U) are regulated in the German standard DIN 16456. They are an economical solution in various applications as an alternative to conventional steel sheet piling. They also make an important contribution to climate and environmental protection, particularly in the rewetting of moors.

Over 1,200 Meters per Month at the Bheri Babai Diversion Multipurpose Project in Nepal
Bheri Babai Diversion Multipurpose Project (BBDMP) is one of Nepal’s 11 National Pride Projects-prioritized plans sanctioned by the Government of Nepal to further develop the mostly rural country. The BBDMP TBM excavation was a success. Nepal’s first tunnel boring machine broke through in April 2019 – about one year ahead of the project schedule.

Plug-in Crosscut Element – How standardised pre-manufactured Crosscut Wall Systems improve overall Tunnelling Effectiveness
The Plug-in Crosscut Element (PCE) is a highly standardised, high precision pre-manufactured and fully assembled ready-to-install concrete wall system. It is designed to close cross connecting galleries in a tunnel in one step. This article explains the remarkable advantages of the innovative PCEs as less manufacturing cost, installation and commissioning time saving, increased safety, and high system reliability.
