The placement of roof requires the completion of rough wall works. The start of the exterior plumbing work is dependent on the completion of rough wall work. Interior plumbing cannot start until the exterior plumbing is complete. Exterior siding cannot start until the roof is in place. The start of exterior painting requires the completion of the exterior siding and the exterior plumbing works. The electrical work can start once the rough wall is in place. Wall board can be placed only after the interior plumbing and electrical works are complete. Flooring and interior painting cannot start until the wallboard work is complete. Exterior fixtures can be installed only after the completion of the exterior painting work. Interior fixtures cannot be placed until flooring and interior painting are complete.
