If a task should last less than a day, such as an inspection that may last one hour, you can set the "Work Days" value to 0 days. The start and finish dates will both be on the same day.
Setting the "Work Days" value to 0 or 1 really only matters if other tasks are dependent on this task. For example, let’s say you have a task of "Pour slab" that is dependent on "Footer inspection." If the inspection is set for Monday and is set for 1 work day, CoConstruct will schedule the slab for Tuesday, since the assumption is that the inspection will take all day on Monday.
However, if the inspection is set to 0 work days, then CoConstruct will schedule the slab to also start on Monday. Here the assumption is that the inspection will not take all day, so the slab work can also begin on the same day.
If you need to specify a time of day for the inspection to occur, you can add the time into the task name. For example, "0800 Footer Inspection". This will provide additional context for your team and trade partners assigned to the task that there is a particular time frame associated with that item.
