We are toying with the idea of putting a 6 man crew together next year. Bit of info... Currently we have 4 -3 man crews ( + 2 maintenance crews that do some small jobs ) and will add either another 3 man crew for a total of 5 or go with 3 - 3man and 1 - 6man. Although we tried it on a couple of jobs this year with great success, I found that I had to be onsite most of the time to make sure things were rolling ... Some concerns - a large crew can go over on projected hours by having one bad day - keeping enough material available to them, because in residential it is not always possible to store materials onsite ahead of time. IM not sure our one truck driver can keep up with all the crews and may be stuck supplying the one. - I think you need a different caliper of foreman then we have to keep everyone working. Some good points - a large crew can do allot of work fast ... 600 hour job in a couple of weeks. - possibly less trucks needed ... our labors get to job site themselves so our trucks are not people movers and generally each crew has either a one or two ton dump and truck driver(for all crews) delivering and hauling away with a tandem..... So ...4 trucks instead of 5 - less equipment??? IM not sure about this ... machine on site may work more hours in the day OR may need 2 machines on site. It has been my experience that the first day on a new jobsite can be kind of slow starting out ...figuring everything out.. marking shrub beds, getting heights etc etc .. this would mean that you would not want 6 the first day. We could send a "start up" crew the first day consisting of 2 or 3 and put the other 3 elsewhere until day two of the job. What am I missing guys/gals???? Any and all comments would be appreciated.
