Initial set of contractors arrived -  spent all day on the project then at end of day informed me that the materials needed for step ONE of the project had not arrived with the rest of the shed and so they "did what they could" -  but it was not anywhere near competion and now has to be dismantled in order to properly assemble with the appropriate parts.  It might have been better to inform me at the START of the project that the floor kit had not arrived with the shed, so that either replacement lumber could have been purchased at the time OR the project rescheduled.  Additionally "pro" called 2 hours after the requested start time to say that he would be there in approximately 90 minutes.
