The ETFE was supported by a cable net to accommodate the larger spans. These were inserted through pockets on the underside of the fabric and the intertwining of the lateral and longitudinal cable mesh helps the fabric resist snow loads and wind uplift. Additionally, a study was carried out on the support cable locations which found that additional cables were needed in certain
locations again to avoid problems with ponding.
