Event Marquees

IMPORTANT INFORMATION

The Crest Tents advertised on our website have been designed and approved by our engineers to meet regulations in Australia. These tents have been designed to comply with “Temporary Structures” regulations and cannot be left up for more than 6 months for any one event. Should the time being used at one event exceed 6 months, it is considered to be a permanent structure and we will need to redesign the frame so that it will comply. This means upgrading the aluminium profiles used so that it can withstand stronger wind gusts. We will need to know the size required and the location that it will be erected so our engineer can make sure the structure is compliant. The frame will need further upgrading if it is in an area that has snow.

There are three ways to anchor the tent to the ground.
1) Steel pins ( for use on standard ground i.e grass or soil surfaces). This is the simplest method.
2) Weight plates. Weight plates are attached to each foot and then concrete blocks are placed on each foot. Our engineer will advise the weight required.
3) If erected on a concrete slab, the frame can be anchored by concrete fixing bolts.

Engineers Notes:

The relevant Australian Standards AS1170.0:2002 General principles, AS1170.1:2002 Permanent, imposed and other actions and AS1170.2:2011 Wind actions are used. The design check is in accordance with AS/NZS 1664.1:1997 Aluminum limit state design.

Design Restrictions and Limitations 2.1 The erected structure is for temporary use only and is limited to 6 months maximum at any one site establishment.

2.2 It should be noted that if high gust wind speeds are anticipated or forecast in the locality of the tent, the temporary erected structure should be dismantled.

2.3 For forecast winds in excess of (refer to summary) – all fabric shall be removed from the frames, and the structure should be completely dismantled. (Please note that the locality squall or gust wind speed is affected by factors such as terrain exposure and site elevations.)

2.4 The structure may only be erected in regions with wind classifications no greater than the limits specified on the attached wind analysis.

2.5 The wind classifications are based upon category 2 in AS. Considerations have also been made to the regional wind terrain category, topographical location and site shielding from adjacent structures. Please note that in many instances topographical factors such as a location on the crest of a hill or on top of an escarpment may yield a higher wind speed classification than that derived for a higher wind terrain category in a level topographical region. For this reason, particular regard shall be paid to the topographical location of the structure. For localities which do not conform to the standard prescribed descriptions for wind classes as defined above, a qualified Structural Engineer may be employed to determine an appropriate wind class for that the particular site.

2.6 The structures in no circumstances shall ever be erected in tropical or severe tropical cyclonic condition.

2.7 The tent structure has not been designed to withstand snow and ice loadings such as when erected in alpine regions.

2.8 For the projects, where the site conditions approach the design limits, extra consideration should be given to pullout tests of the stakes and professional assessment of the appropriate wind classification for the site.
