If you’re out erecting marquees at the moment then it’s a bit cold but you should avoid using heaters to warm you up, at least until the flooring is down.
Putting marquees up in bad weather isn’t the greatest but we do work in an industry that means once the marquee’s up we’re effectively working indoors for the rest of the time whilst finishing off the interior of the marquee.
If you put the marquee up on frozen ground and then put the heater on you risk working in a bit of a quagmire as the ground thaws out and the mud gets spread around the marquee.
Simple solution -don’t put the heaters on until the flooring is down, that waterproof barrier under the flooring will keep the flooring sound as the ground thaws out.
