ARE 4.0 has 7 divisions, and for those who are looking to get the process started, the amount of information can seem overwhelming and intimidating. When they are trying to figure out their exam orders, they often want to know which exams overlap most so they can schedule those back to back or study both at the same time. While I was procrastinating instead of studying last night, I thought, maybe I can visualize it with a venn diagram. I have only taken 5 tests (passed SD, PPP, BS and SPD, failed SS), but I think I’ve read enough to make a summary. Here you are- all 7 exams and their contents in one poster. You can click on the division to access NCARB’s official exam guides. You can also click on the links at the bottom for my blog and pinterest page with additional ARE info.


The Multiple Choice
There is a general consensus that CDS, SPD and PPP belong to one group (left half of the diagram), while BS, SS and BDCS belong to another. In my opinion, BS and SPD actually also have some significant overlaps, as illustrated above.  Unfortunately I could NOT get the sizes of the circles to correspond to the amount of materials in each test– SPD and PPP are definitely much “lighter” tests. As you can see in the diagram, these two have minimal exclusive topics and a whole lot in common with others. SS is almost the opposite.

Now I am not saying they can’t ask you how elevators work in CD or test your structural concepts in PPP… because they can. But as far as studying goes, this is pretty much it. Most people take all three of the same group and then move onto another group, but I personally chose something that looks more like a heavy-light-heavy-light order.

SD is a stand-alone satellite, it has NO multiple choice questions, and is the easiest (although of course, one should by no means underestimate it). People either take it first, because it can boost their confidence; or they take it right in the middle, so they get an easy pass through the mid-way hump; or they take it last, because there’s nothing worse than failing your last test and waiting for 6 months without doing anything.

In the center of the diagram is ADA, IBC and zoning. They matter more to some exams than others, but in general they are sprinkled throughout. You can really get any code-related questions in any test. So, no matter which test you are taking first, start by getting your hands on the codes and you will benefit from it. You will find yourself going back to it for every single test.

The Vignettes
Vignettes are generally easier than MCs. Most of them can be prepared for within a week. Out of all 11 vignettes, I’d say SD’s interior layout, BS’s M&E plan, as well as SPD’s site design are a little trickier than the rest, mostly because of the time limit you are given. Anyway, all it takes to pass the vignettes is a little patience, the ability to follow directions, and attention to detail. Practice, develop a strategy for each type, be careful, and you will be fine.

I have 3 more test to go, so I am somewhere between seeing light at the end of the tunnel and having a long way to go (I have to RE-take SS for crying out loud!) So far I think getting started is THE hardest thing to do. Once you get your feet wet things will pan out one way or another, and so I hope this article will give you an overall idea of what it’s like and make the first step a little easier. Please feel free to share it and/or leave me some comments. Good luck fellow ARE-takers!

Difference between Malleability and Ductility

“The difference between malleability and ductility is that malleability is the ability to deform easily upon the application of a compressive force, and ductility is doing the same with tensile force.

*Ductility is a mechanical property used to describe the extent to which materials can be deformed plastically without fracture.

In material science, ductility specifically refers to a material’s ability to deform under tensile stress; this is often characterized by the material’s ability to be stretched into a wire.

Malleability, a similar concept, refers to a material’s ability to deform under compressive stress; this is often characterized by the material’s ability to form a thin sheet by hammering or rolling. Ductility and malleability do not always correlate with each other; for instance, gold is both ductile and malleable, but lead is only malleable. “

Difference between Laitance & Efflorescence

Laitance and efflorescence are really two completely different things, but they are both white, powdery substances, which can be confusing.

In short, laitance is formed when there’s too much water in the concrete mix, while efflorescence is the deposit on masonry surfaces caused by soluble salts in the units or in the mortar.

Laitance can be avoided by controlling the amount of water in the concrete mix. Efflorescence can be prevented, or at least minimized, by selecting materials free of harmful salts and by preventing water from penetrating the masonry. This may be accomplished by the use of solid and tight mortar joints, capped walls, effective flashing, and adequate weather protection of the masonry during construction.

Both laitance and efflorescence can present both cosmetic AND structural problems.

Air Entrainment

Air-entraining agents is a type of admixture.

Air entrainment is the intentional creation of tiny air bubbles in concrete. The bubbles are introduced into the concrete by the addition to the mix of an air entraining agent, a surfactant (surface-active substance, a type of chemical that includes detergents). The air bubbles are created during mixing of the plastic (flowable, not hardened) concrete, and most of them survive to be part of the hardened concrete. The primary purpose of air entrainment is to increase the durability of the hardened concrete, especially in climates subject to freeze-thaw; the secondary purpose is to increase workability of the concrete while in a plastic state.

Origami Christmas Tree

“Architect’s Christmas Tree” made from architectural drawings

As the holiday season approaches, I decided to take a little break and have some fun. Every year I try to make something architecture-related by recycling some of the paper from work. This year I made an origami Christmas tree with some drawings. I call it “the architect’s christmas tree”. I like the sculptural yet structural quality of it. It’s not super easy, but it’s also very forgiving. The print on the paper gives it some texture and any imperfection just makes it more organic. You can of course also use any other paper- renderings, magazines, sheet music etc.

You can make your own by clicking on this link or watching this youtube video:

The one I made last year (in the background) can be found here.
Have a witty, classy and environmentally-friendly christmas. Enjoy!
