The Business of Big Tops
by David Clark, President, BCEM
BC EVENT MANAGEMENT (BCEM) HAS RECEIVED TWO Star awards and two nominations for Best use of Tenting from the CEIA, including one at the 2007 Star Awards. BCEM has also received two Gala awards from Special Events Magazine for Best Tent Installation including the installation for Bill Gates’ wedding reception.
We asked BCEM President David Clark for some pointers to those planning larger tented events. Here is his advice:
Choice, Siting and Installation
There are various categories of tents: Frame, Pole,Tensile and Structure.
The biggest mistake planners can make is to choose a tent that cannot support their production. In other words if you are designing a high end event with the usual suspended production, confirm that the tent you choose can support the weight of your lights, audio cabinets, and video projectors (if applicable).
Don’t choose a windy location. No matter how elegant your event is, it will be compromised by wind noise and billowing walls, or worse, tumbling centrepieces and blowing linens. Make sure you inspect your tent site at the same time of day as your event. Winds often settle down in the evening.
Don’t assume that you can release your tent contractor once the tent installation is complete. If the weather is at all unsettled keep at least one tent crew member on standby during the event to add or remove walls as needed.
Weather Concerns
Water (rain) management is a huge issue with tented events.
The most pristine set up can quickly turn ugly in a downpour, especially if you have not inspected the site in the rain and planned accordingly. Inspect the terrain where your tent is going to sit on a wet day. Note where puddles form and how water drains on your site. Note how quickly the ground absorbs water. The terrain might seem OK when you are at the site inspection in casual shoes but have a staffer try high heels to see how the terrain responds to heels.
Elegant events call for a carpeted floor. The only totally safe solution if rain is a possibility is a raised floor. Even then the water can run down the tent walls and blot into the carpeting. The only bullet-proof solution is to have the tent legs straddle a raised sub floor. In this manner the rain water running off the walls never comes in contact with the carpet. Tents that butt up to each other require gutters to prevent drips between tents.
In hot weather air conditioning is required as walled tents can get very stuffy since they do not have the ventilation systems that buildings do. Clear roofs and walls can exacerbate the problem on sunny days. Chillers (air conditioning units) require a lot of power - more than any site is likely to have unless it is designed for events. Generators therefore have to be provided. Be careful with positioning of the generators as they can be noisy and generate fuel smells. For both these reasons position them downwind. We like to mask them with a row of hedges. This also dampens the noise. Heat is easier to power as it can be propane driven and hence only requires power for the fans.
Budget
Tent prices vary considerably.
Keeping large tents spotless requires large cleaning facilities and much elbow grease to keep mildew absent and water and mud stains at bay. Vinyl has a shelf life and needs replacing periodically. Clear walls are popular but they show their age more quickly than opaque walls. Confirm that clear walls and roof panels are in good shape when you reserve your tent.
This maintenance and upgrading is reflected in your rental price. You get what you pay for. Don’t be surprised if you don’t get sparkling clean, new looking tents, from the lowest bidder.
Utilities and Safety
Kitchen tents are the most dangerous and complicated areas in event tenting.
In many jurisdictions a health inspector is required to sign off on the kitchen set up. If propane stoves /ovens are used a certified pipe fitter may be required to connect the cooking equipment to the tanks and a gas inspector may be required to certify the connections. The gas inspector will also require venting (stove hoods/fans) in any tent housing cooking equipment. Do not assume your caterer has taken care of these issues. Many ignore the red tape as gas inspections are rare. If the weather permits you can avoid this red tape by cooking outdoors.
Anchoring
All tents require anchor stakes and tension tents require especially deep anchors.
The event planner or tent company must determine what lies below the surface that you are anchoring to. Be sure to avoid sprinkler lines. The type if soil is also an issue. Tensile tents require packed soil - any loose or sandy soil will not hold the anchors. Reclaimed sites can also be a problem since old concrete footings might prevent anchors from penetrating. On concrete surfaces concrete anchors can be used. Asphalt cannot be anchored into, as it is too soft, but you can anchor through it. Plan on patching both asphalt and concrete before you leave the site.
The strangest anchoring case we have run into was at Fort Langley National Historic Site where an archaeologist had to certify that our longer anchors would not disturb native burial grounds.
Weights
In areas where anchoring is not possible (e.g. artificial turf fields, tiled plazas) weights have to be used instead.
Weights are usually one of two types: concrete or water barrels. Water barrels are the most practical since they can be filled and drained on site thereby avoiding the requirement for heavy equipment to move them. In certain situations only the increased weight of concrete will do. Unfortunately they require forklifts to move them into place. That in turn creates new problems. Some sites will have limits on the weight of lift trucks allowed on to the site. To avoid marring the surface, or causing depressions on sports fields, plywood sheets have to be laid down everywhere the lift truck moves.
Tent Height
Tents are often available with more than one height of leg.
Most events benefit from the longer legs to accommodate sightlines to projections and to get suspended lighting as high as possible. If planning a fair weather event with no walls, confirm that walls are available to match the longer legs in case you have to add walls at the last minute. With careful planning your tented event will be a huge success.
