Building, Construction Materials and Technologies Exhibition

42nd Yapı - Turkeybuild Istanbul
18 - 22 June 2019 • Istanbul, Turkey, TUYAP Fair and Congress Center

Day 2 video round-up: watch it here

YAPI Turkeybuild’s second day started where the first left off, with busy aisles, busy schedules, and busy seminar arenas. Watch the second day’s roundup here:
What other highlights did the second day bring?

Hosted buyers

Making an appearance on the second day were the members of the Hosted Buyer programme – buyers from the Middle East, North Africa, Europe, Central Asia and elsewhere came specifically to Istanbul to meet suppliers and make new partnerships among the exhibitors.

One of the fair’s guests was R. Venkatesan, Procurement Manager for the HBK Contracting Company in Qatar. “We have come to YAPI Turkeybuild Istanbul to look for new suppliers and subcontractors, and to expand our business horizons. We have had several meetings already by the second day, both in the YAPI Turkeybuild Hosted Buyer lounge and at the individual stands of the exhibitors,” he said.

Learning from nature with Achim Menges

One of the highlights of the second day was Prof. Achim Menges from the University of Stuttgart’s Institute for Computational Design and Construction. His institute applies fresh thinking to building projects in and outside Germany – taking inspiration from nature as the main principle.

Prof. Menges presented the Landesgartenschau exhibition hall project to YAPI Turkeybuild – a design inspired by the plated skeleton of a sea urchin. The project used interlocking wooden elements to form the entire load bearing structure of the walls and ceilings in a cocoon shape. Taking natural inspiration like this allowed for some remarkable saving in weight and materials – the 605 cubic metre space of the exhibition hall was covered by just 12 m3 of timber – and this produced enough offcuts to build an entire hardwood floor for the hall. The structural precision of this technique allowed for some seriously thin parts – the average thickness of the wooden shell was just 50 mm.

Menges and his institute are not stopping there. Buoyed by this success, he’s applying the learnings of his institute to bigger and more ambitious projects – jobs in the pipeline include a more conventionally-shaped factory ceiling to cover a 30m by 170m area.

As this technique is so lightweight, the real excitement in the building community is what Menges’ idea can offer for extensions. Building on top of existing structures can rest on a knife-edge, but the thinness and precision of this interlocking shell system allows for construction on a much more ambitious scale. The Institute is starting fairly small – they are adding two floors to a multi-storey car park in Germany – but the possibilities and weight savings offered are grabbing the interest of contractors and project owners.
