Height

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

To Tip:

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).

Floors

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.

Structural Material

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 a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced 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.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/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 in a composite building’s core, columns, and floor spanning separately.

About MahaNakhon

MahaNakhon is a mixed-use development providing residences, retail, hotel and an observatory in the heart of Bangkok. Located in the Silom business district, directly adjacent to the Bangkok Skytrain public transport system (BTS) and Bus Rapid Transport System (BRT), MahaNakhon is Thailand’s tallest building.

The inner city site is irregularly shaped, resulting in a three building program, the main 314m tower, a smaller retail building at the front of the site and an automated parking tower positioned towards the back. The form of the tower has a distinctive sculptural appearance which takes advantage of the tropical climate and views. The three dimensional ribbon of architectural pixels cut away the façade of the tower to reveal the inner core, creating unique one of a kind residences as well as special features such as oversized terraces and skyboxes, protruding out from the main building.

The main structure and life core is wrapped by a series of mega columns, connected at several transfer floors, and the pixelation means 30% of the tower’s floor plates are in cantilever. The building uses 129 piles drilled to a depth of 65 meters capped with a massive 8.75 meter thick mat foundation, to compensate for Bangkok’s soft soils. Construction began in 2011, requiring a design-build approach with construction staged in a manner to allow for a steady delivery of material deliveries working around Bangkok’s high levels of traffic congestion. Seismic design used CTBUH recommendations and the unconventional form has been tested with 36 directions of wind load during wind tunnel testing. The tower was officially completed in 2016.

MahaNakhon means ‘Great Metropolis’ in Thai language, and integrates with the city through its organic form by dissolving the mass as it moves between sky and ground, flowing into the large outdoor retail spaces into a public landscaped square at the tower’s base. The development brings in several international brands including leading restaurants and dining adjacent to the main street, The Bangkok Edition Hotel in the lower section of the main tower, with Ritz-Carlton branded freehold luxury residences in the upper section of the tower. At the top of the tower, a multi storey observatory and bar tourist destination showcases the views of Bangkok.
