Article Peer Review
Hi Monica,

I've read through it a couple of times and have the following comments. I hope they’re helpful.

Best, Adrian

++++++++++++

1.	(minor thing) you can use the “Format” tab to put the section headings in a larger font

2.	I think you could expand on the introductory/overview paragraph to give a better sense of why someone would use a Waffle Slab (e.g. lower cost, ease of construction, added strength). That would put the rest of it into perspective. Maybe just merge the first two paragraphs together. If you know, you could give some examples of other types of flooring that could be used for the same job, but aren’t as good as it as the WS is.

3.	For the Construction Process section, I think you could skip the list of forms needed if you can provide a general description of how they’re used. Something like “Waffle slabs are constructed by arranging generic forms in the desired shape and then filling them with concrete.” Or, maybe provide some sort of description of what the forms are and do? It just seems like a list with no description doesn’t provide much help to the uninformed reader (i.e. me).

4.	Why are there three ways the slabs are manufactured? Does one some have benefit over the others?

5.	In Rules of Thumb, what does “Slab/24” mean? 1 inch thick for every 24 inches wide?

6.	I’d rewrite the second bullet as: “Ribs are typically 5 inches to 6 inches wide and have steel rod reinforcements.”

7.	Advantages/Disadvantages: I think these sections would be clearer if you set them up with a general intro sentence (“Waffle slab construction has several advantages:” and then follow it with bullet points.

8.	Grammar: there are a lot of minor grammatical errors, e.g. A Waffle Slab or Two way joist slab is a reinforced concrete…; The Waffle Slab is flat and thin on top while joists create a grid-like surface…; The system is composed by of intricate forms… Give it a good review to be sure you catch them all.

9.	“Other Considerations”--I think you want this to be “Sources”, instead.

Hi Adrian, Thank you for all the pointers, for sure will use them! Monica! Moniortz (talk) 21:03, 28 November 2018 (UTC)

Instructor comments
This is a good start that covers the basics of waffle slabs, but as your peer reviewer noted, it could use a good copy edit.

Your plan for the article included finding examples of structures with waffle slabs (e.g., the Washington Metro shown in the Constructor reference), which would help tie this article into the rest of Wikipedia.

Finally, it would be useful to compare waffle slabs to other structural systems such as ordinary concrete slabs, voided biaxial slabs, etc.Elizabeth Linden Rahway (talk) 12:28, 1 December 2018 (UTC)

Outdated?
The article states "Waffle slabs are preferred for spans greater than 40 feet (12 m), as they are much stronger than...". However my observation is that all new buildings are using post-tensioned slabs, which are much thinner yet strong. I'm not an expert on the subject and haven't found a source listing the prevalence of each type. - SCEhard T  19:31, 16 February 2022 (UTC)
