• Thank you, Rebekka.

Actually, I have been participated in booth camp even though I do not have to attend any more since I passed too fast. I saw your website (Step Up ARE Prep) which is well organized with high quality contexts & believe many ARE prep designers will greatly benefit from it too. When I started ARE 3.0, it was really no help but Ballast. So I am so happy to see this movement of online supports.

Thank you again for your compliment & good luck for your endeavor to share your know-how with others thru Step Up ARE prep!

• I am impressed by your very inspiring story. Now you are a happy camper. Congratulations!

• Thank you & Good luck for your exam, Tamiko!

• Hello Hang,

Congratulations on your well deserved success, impressive will power!

I have one last hoop (PDD) to jump, but certainly want to jump on  LEED AP & BC+D as a next step. Wondering if you'd be interested in partnering on LEED resources this study?

• Hi All,

I was reviewing a cost estimating questions on cost escalation brought about due to inflation, the solution per WeARE is as below; can someone help me understand where the (1.02)⁴ came from? How did a 2% inflation/year become (1.02)⁴? Thanks in advance.

The Wright family wants to build a new museum in Phoenix. This new space is almost identical to another museum built 4 years ago in Chicago by the same Wright Foundation, for a total cost of \$3,123,000. If the construction cost index of 104 for Chicago and 92 for Phoenix, and assuming an annual inflation of 2%, how much will the new museum cost?

0 / 1 points

Construction Cost Estimates

• \$2,983,666

• \$2,990,385

Clarification:

Correct answer is A - \$2,990,385

First thing we should do is calculate how much it would cost to build the new gallery 4 years after the original one, based on an annual 2% inflation:

\$3,123,000 x (1.02)⁴
= \$3,123,000 x 1.08243216=
\$3,380,435.63568

Then we need to calculate the cost of building the same gallery in Phoenix, based on the cost index of both cities.
(92 ÷ 104) x \$3,380,435.63568 = \$2,990,385

question on WE ARE

Dear Bankole

1. Thank you, but I am already studying LEED.

2. It is because 4 years ago. (you have to multiply 1.02 four times).  I think it is a shortcut.

• I thought that too at first, but...2% = 0.02, multiplied by 4 is 0.08, not 1.02. Or am I missing something?

• (Edited )

shortcut

\$3,123,000 x 1.02 (1st year) = \$3,185,460 x1.02(2nd year) = \$3,249,169 x 1.02(3rd year) = \$3,314,152 x 1.02(4th year) = 3,380,436 (total cost after the increase due to 4 years annual inflation)

longway

\$3,123,000 x .02 = \$62,460 (1st year increase) so total cost after 1st year inflation is \$3,185,460

\$3,185,460 x .02 = \$63,709 (2nd year increase) total cost after 2nd year inflation is \$3,249,250

\$3,249,250 x .02 = \$64,985 (3rd year increase) total cost after 3rd year inflation is \$3,314,235

\$3,314,235 x .02 = \$66,285 (4th year increase) total cost after 4td year inflation is \$ 3,380,519 (very close)

By the way, in real exam, better to use shortcut ....

• Did you feel the complexity and detail of Elif's Questions are similar to the content in the exam?

• Congrats on passing! This is one of the most difficult exams, so it definitely is a big accomplishment! If anyone else is look for study tips and tricks for the PDD exam, I made a YouTube video explaining everything I did in order to PASS this exam. Check it out and be sure to subscribe to my channel so you don't miss out on any future videos. https://youtu.be/hXHFKlN-Bx4

Note: I made a video for each of the ARE 5.0 Exams, check them out on my channel.

• Congrats Hang!  It IS a big accomplishment!

Just curious, why are you mentioning 'boothcamp' in your post if you didn't use it to study?  Who specifically told you to include that??  I don't usually recommend products I haven't used.  Do you??
