ZURICH — Registrations in the 3rd International Holcim Awards competition to promote sustainable construction will close on March 23, 2011. The competition encourages building solutions and visions that go beyond convention to address the challenges of sustainability.

The Holcim Awards (main category) is open to architects, planners, engineers, project owners, builders, and construction firms with current projects that showcase sustainable responses to technological, environmental, socioeconomic, and cultural issues of contemporary building and construction. Projects must be at an advanced stage of design, but construction/production must not have not started before July 1, 2010.

In addition, the Holcim Awards competition seeks visions and ideas for the "Next Generation" (student category), open to projects created within any university program at final year bachelor level or above (including master’s and Ph.D.).

A step-by-step guide to entering the competition is available for download in seven languages, covering the conditions of entry, adjudication process, and tips on completing the online entry form. Entries must be registered by March 23, 2011, in English only, at www.holcimawards.org.
