Use of "as well as"

[Unregistered]

I'm wondering about the use of "as well as" in place of "and" near the end of a list. For example, I recently read the sentence:

Some additional tasks have included providing a market study, supplying a cost analysis and budget breakdown, as well as providing a Gantt chart.

I find the use of "as well as" awkward here, and would be more inclined to put "...budget breakdown, and providing a Gantt chart."

Is there a grammatical or style concern with this usage of "as well as"? This is from a paper that I am marking and I would like to know if I should suggest making changes, particularly since I have been finding this usage very common throughout the papers that I mark.

Thanks for any suggestions.

Hello
as well as is a conjunction word
It means in addition

You could say:

Some additional tasks have included providing a market study, supplying a cost analysis and budget breakdown, and providing a Gantt chart.

However, as well as serves just as well as and, and, as another poster noted, in the aforementioned context it means the same as in addition to.
