I hope the dates have been chosen as it is to be 7 day working, with the dates set to include 3 weekends.
Even more ideal would be if it includes multi-shift working where this actually assists progress (sometimes it's unavoidable that work has to pause for material to set, or it's prohibitively expensive to get the materials out of normal working hours of concrete/bitmac etc plants.) Availability of workforce being a genuine constraint. too - it's not just bus comapnies that can struggle for staff.
