Function
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 CVU "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.
Hotel / Residential / Office / Retail
Structural Material
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 CVU database breaks out the materials used within a composite building’s primary structural elements.

Owner/Developer
Architect
Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.
Structural Engineer
The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.
The Engineer of Record takes the balance of the engineering effort not executed by the “Design Engineer,” typically responsible for construction documents, conforming to local codes, etc.
The Peer Review Engineer traditionally comments on the information produced by another party, and to render second opinions, but not to initiate what the design looks like from the start.

About Lotte World Tower
Taking inspiration from traditional Korean art forms in the design of the various interior program spaces, the sleek tapered form of Lotte World Tower will stand out from Seoul’s rocky, mountainous topography. The tower is programmed with a greater variety of functions than is normally found in a tall building. It contains retail components, offices, a 7-star luxury hotel, and an officetel. Officetels, common in South Korean real estate, offer studio-apartment-style accommodations for people who work in the building and often feature certain services found in hotels, such as furnishings, a security desk, and gym access. The building’s top 10 stories are earmarked for extensive public use and entertainment facilities, including an observation deck and rooftop café.
The design of the tower melds a modern aesthetic with forms inspired by Korean ceramics, porcelain, and calligraphy. The seam that runs from top to bottom of the structure gestures toward the old center of the city. Elegance of form was one of the prime objectives, following the desire of stakeholders to bestow a beautiful monument to the capital city skyline. Exterior materials will be light-toned silver glass accented by a filigree of white lacquered metal.
Lotte World Tower has been designed and constructed at the same time as a 10-story base that accommodates as much area as its vertical counterpart. Vertical density is linked to horizontal density, and the range of complementary uses is increased. Connections between the two major building components are made via interior pathways at many levels, but also by active outdoor public space. In fact, one of the most effective measures taken to activate the tower and connect it to adjacent buildings is the outdoor plaza. This space forms an “outdoor room,” compressed enough in its dimensions to encourage visual and pedestrian penetration of its boundary walls.
