Call for submissions: IASS WG21 Expo

Registration date:


Submission date:




After the success of the 2015 IASS expo in Amsterdam and the 2019 expo in Barcelona, WG21[1] is organising a new exhibition to celebrate this success during the annual international symposium of the IASS and the 7th international conference on Spatial Structures. The expo, symposium and conference will take place in Surrey from 23 to 27 August 2021.

Internationally recognized and celebrated artists, designers, engineers, and researchers in cooperation with top universities from all over the world are invited to participate in a contest and exhibition of innovative lightweight structures. The structures must display a strong vision of structural design and innovation. They should demonstrably be the result of structural engineering focused research projects. It is our ambition to have an exhibition that shows new insights on structural typologies, through the design of a pavilion. The pavilions will be exhibited during the joint IASS - Spatial Structures 2020 symposium in Surrey UK. During the conference the jury of the contest, will award a prize to the most innovative realized structure.

The winning team will be awarded a prize of €1000 and certificate signed by the jury.

The competition brief is to design an innovative lightweight pavilion/structure. The structure will stand outside at the venue of the University of Surrey. There are no maximum external dimensions but it has to be transportable by airplane. Therefore it has to fit into six boxes each with a maximum external size of 1x0.75x0.65m and maximum weight of 32kg (total pavilion 192kg). The structure should reflect structural engineering research of the submitting team. Each structure will be judged by examining the production techniques, materiality, and level of structural innovation, constructability, transportability, architectural expression, overall originality, and transfer with art of the finished pavilion. The choices of materials, manufacturing methods, erection techniques, and so forth are at the entire discretion of each team. Innovative ideas and prototype methodologies that push the boundaries of construction are strongly encouraged.

All entries to the competition are made by completing the online application form available on the WG21 website.

The pavilion contest consists of three phases:

Phase 1: Initial proposals

August 2020: Provision of design rules and other conditions.October 2020: 2D model of the expo venue will be provided on website.31st January 2021: Submission of initial team proposals, allowing safety check by local authorities (it is possible to submit a preliminary design first and the final design later.)14th February 2021: Acceptance of proposals and payment of contribution. WG21(the organizers will send an invoice to the team or sponsor of the team.

Phase 2: Detailed design and construction

February-August 2021: finishing of the Design and realization by each team of their pavilions as a “transportable kit”. This stage will include detailed design submissions to IASS and WG21. Thursday 19th August – Saturday 21st August 2021. Building of pavilions in Surrey, undertaken by each team.

Phase 3: Exposition

Official opening of the exposition Monday 23rd August 2021 Exposition paper session during IASS Structural Membranes Symposium. Award ceremony during closing of the Symposium. Removal of pavilions by each team, 27th August 2021.

During the symposium in Surrey there will be a special session organized by WG21 about the exposition. All participants will be invited to submit a paper about their pavilion. Papers will be reviewed by the scientific committee of the symposium (not by WG21). After acceptance, papers will be published in the symposium proceedings. For the timeline of the paper submission please look at the website of the 2021 Surrey symposium. A special issue of the IASS journal on the 2019 exposition and 2021 expo is planned to be published in spring 2022. All participants are invited to submit a paper for this special issue of the IASS journal.

During the 2021 Symposium the jury will select one winning pavilion. The prize of €1000 will be awarded at the symposium. The jury will judge the structural pavilions against the following criteria:

The jury will be recruited from: • Organizers of the symposium • Symposium scientific committee • Board of IASS • Local officials.

The cost for the exhibited structures and organization of the expo will be covered in full by the participating teams. The teams are allowed to invite participating companies, universities etc. to contribute to the exposition by sponsoring in money or in kind (materials and services).

The designs may be produced and realized in cooperation with the supporting company. Companies will have the opportunity to highlight their contribution by showing logos and by providing information about their activities during the Expo. The fee for the participating teams will be calculated using the following formula:

· Fee = €500 euro minus 0.025 x the distance to London in kilometres[2]. The distance between the cities can be calculated at this website. For instance, the participation fee for a team from Paris, will be €491.40; for a team from Melbourne it will be €77,52. This fee is for entry to the competition only and does not include registration at IASS 2021.

At least one member of every participating team must represent the team at the symposium in Surrey in 2021 by registering as a presenting author and paying the corresponding registration fee.

Practical matters and conditions

This contest is organized by IASS Working Group 21 in close cooperation with the symposium organisers of the University of Surrey. The complete information about the contest, rules, jury, etc. will be announced on our website.
