Hi
In theory you are correct two men should do double one man but lee is right it doesnt seem to work.
I thinl its down to little variables.
1. setting up hoses seems to take the same time with two as one so you loose a bit there especially on spread out work where your moving on after each property.
2. dealing with the customer if one is grabbing the money and keep it friendly with the custie, whats the other doing if he is finishing of fine but having a fAg theres 5 minutes gone.
3. travellling this is the killer i think if its 10 mins between each job your loosing 20 mins of actual work this adds up.
4. if we are talking employees theres the chat factor, on there own they will just get on with it, together they can loose an hour a day chatting.
I think it works when there is a lot of work together so you can be on several houses from one point, or commercial. It can come close if you have it so organised it like a military campaign. so every one jumps out the van, knows what kit there using , whos doing what, whos going where. then you reduce the lost time and you can get close to double.
where it is useful is if you get a young un on board. he can be with an experienced hand so you know work wont get bumped
you wont hit double then but you shouldnt be paying the trainee the same so can work out.
cheers
