Burj Dubai tier methodology

Burj Dubai tier methodology to help show which direction the terraces face. A 360 degree directional compass was used for the approximate direction the points of the wings face.

Tier 30 Top is a platform 1.5 M diameter with a hatch.
Tier 30 - pinnacle 4 is circular 1.2 M diameter.
Tier 29 - pinnacle 3 is circular 1.35 M diameter.
Tier 28 - pinnacle 2 is circular 1.5 M diameter.
Tier 27 - pinnacle 1 begins with tier 26 terrace facing 180, then rises up circular 2.1 M diameter.

Tier 24, 25, and 26 wings are 1.5 M long.
Tier 26 - spire 5 begins with tier 25 terrace facing 60 then rises up with 1 wing facing 180.
Tier 25 - spire 4 begins with tier 24 terrace facing 300 then rises up with 2 wings facing 60 and 180.
Tier 24 - spire 3 begins with tier 23 terrace facing 240 then rises up symmetrically with 3 wings facing 60, 180, and 300.

Tier 21, 22, and 23 wings are 6 M long.
Tier 23 - spire 2 begins with tier 22 terrace facing 120 then rises up with 1 wing facing 240.
Tier 22 - spire 1/roof 4 begins with tier 21 terrace facing 0 then rises up with 2 wings facing 120 and 240.
Tier 21 - roof 3 begins with tier 20 terrace facing 240 then rises up symmetrically with 3 wings facing 0, 120, and 240.

Tier 18, 19, and 20 wings are 6 M long.
Tier 20 - roof 2 begins with tier 19 terrace facing 120 then rises up with 1 wing facing 240.
Tier 19 - roof 1 begins with tier 18 terrace facing 0 then rises up with 2 wings facing 120 and 240.
Tier 18 begins with Tier 17 terrace facing 300 then rises up symmetrically with 3 wings facing 0, 120, and 240.

They are working on the first level / section of tier 18. We can see the terrace faces opposite of the shot - 300 degrees and the 3 wings of tier 18 facing 0, 120, and 240 degrees. Then tier 18 top (first section of tier 19 terrace) faces 0 degrees (North) or where Ember's 20 is. The methodology can then be followed to get the rest. Also tier 27 to 30 are circular.
