  Floors
Above Ground
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

Hotel

Structural Material
All-Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered an “all-steel” structure as the concrete elements are not acting as the primary structure.

All-Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars and/or steel reinforced concrete which has been precast as individual components and assembled together on-site.

All-Timber
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from timber. An all-timber structure may include the use of localized non-timber connections between timber elements. Note that a building of timber construction with a floor system of concrete planks or concrete slab on top of timber beams is still considered an “all-timber” structure as the concrete elements are not acting as the primary structure.

Mixed-Structure
Utilizes distinct systems (e.g. all-steel, all-concrete, all-timber), one on top of the other. For example, a Steel Over Concrete indicates an all-steel structural system located on top of an all-concrete structural system, with the opposite true of Concrete Over Steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used within a composite building’s primary structural elements.

About Baiyoke Tower II

Rising from the Pratunam area of Bangkok, Baiyoke Tower II is Thailand’s first supertall building and Bangkok’s tallest building for 19 years until the completion of MahaNakhon in 2016. It was developed through the Baiyoke Group of Hotels following upon their success with Baiyoke Tower I, located one block to south and completed in 1987. The first Baiyoke Tower was the tallest building to rise in what was at the time, primarily a garment district full of low-rise buildings aligned to narrow streets doubling as open-air markets. The second Baiyoke Tower from the onset was to be even larger and was designed to not only be the tallest building in Thailand, but also the tallest hotel and tallest reinforced concrete building in the world. Initial planning begins soon after the completion of the first tower and construction then began in 1990.

The design was inspired by the traditional architecture of Thai temples with triangular rooflines accented with gold color. These features were to be included on what was initially proposed as a red colored exterior, envisioned as a block of red sandstone ascending from the earth skyward while sculpted and hallowed out for human occupancy. While the red color was not included in the finalized design, the tower’s form does adhere to the idea of monolithic block of stone rising from the ground. The exterior is largely made up of a grid of small windows on a tower form which begins as a large podium base and then becomes more slender through a series of terraces and upper level setbacks marked by golden triangles.

Economic downturns stalled completion of the tower until 1997, after which it became a redefining feature of the Bangkok skyline. The tower’s first four floors and the basement are dedicated to retail use while parking assumes the role of the next 10 floors of the large podium base. The hotel spaces are then allocated to the tower as it rises above the large base with the podium roof featuring an outdoor deck and swimming pool. The uppermost floors include restaurants, lounges and public observatories on the 77th floor and the 84th floor.
