King Abdullah Financial District

Today's Architecture

  Parcels 407 and 408 are mixed-use, and are developed as one combined lot with two towers - 88 meters and 133 meters tall. The site has its longest eastern face to the Wadi, and along this edge the design has 3 levels of continuous retail and public space. 

One pedestrian bridge enters the site across the Wadi at the +1 level. The northern edge of the parcel faces a large plaza and a science museum attractor, and the taller tower is situated along this edge of the parcel. The western edge of the site is bound by an access street. The primary vehicular drop off is located along this edge, and the tower lobbies front this main thoroughfare. 

Two bridges enter the site above the access street on the +1 level. The southern edge of the site is a sloped cul-de-sac that provides public access from the street to the Wadi. The shorter tower is situated on the corner of the cul-de sac and the access street. The cul-de-sac is also utilized for access to the garage and service/loading level below grade. Each façade is conceived to adjust to meet the design requirements of its particular orientation while maintaining continuity within the development.

Parcel 209 is a residential development with facades facing a shared cul-de-sac to the north and access street to the east, a public square to the south and the Wadi to the west. The development is connected at the skywalk level to adjacent developments via a pedestrian bridge to the north, and an additional bridge to the south. The access street provides a shared drop-off, as well as access to below grade parking, and a landscaped pedestrian route to the Wadi. At the middle of the combined drop-off is a landscaped pedestrian walkway leading to the residential lobby and beyond, with stair and elevator access to the Wadi below.

Multiple programs for Parcel 214 include office, residential, retail and religious components. A 26-story office tower is located in the middle of the parcel to take advantage of open north and south view corridors through adjoining sites.

The residential building engages the tower within the lower recessed portion as an architectural gesture and becomes part of the tower façade that faces out onto the mosque and its plaza below. The tower in turn inflects its west and east façades to acknowledge the presence of the mosque on one side and the residential terminus on the other.

Open spaces are defined by two public pedestrian thoroughfares that connect the street to the Wadi on the east and west sides of the tower. One is used for residential entry at ground and skywalk level, while the other is for mosque use. Public access occurs at entry lobbies into the office tower, residences and retail.

Landmark Project in Sweden

Today's Architecture


 The softly shaped building symbolizes the human values characterizing the revival of Vällingby Parkstad in Stockholm, Sweden.Danish architect 3XN has won the Landmark Project in Sweden, the construction is planned to begin 2011.

 It was important for us to create a contrast to the traditional and more angular buildings surrounding the site. This building will add human values and scale to the area – and at the same time it will be a significant landmark for the Vällingby Parkstad, says Jan Ammundsen, Partner and Head of Competition at 3XN

The building’s curved design embraces the area and the lively shaped balconies opens up the structure towards the surroundings thus raising the park up in the air. The dense city structure at the base adds activity at eye level and life thrives on active roof tops and flowering balconies.

What are consider selection of equipment cost?

Equipment costs rank second to labor costs in term of uncertainty and in their effect on the outcome of anticipated profit for a construction project. Many factors can influence the selection of equipment in the construction project. These factors are considering equipment selection.

Task Consideration

Nature of work  This cost depends on the size of the job, the distance of transportation, and the means of transportation

Daily or hourly forecast of planned production

Distribution of work at site

Quality of work and tome allowed for completion

Interference expected and interdependence with other operation.

 Site condition:-  

Accessibility to location

Maneuverability at site

primary site condition factors are type of material to be handled. Physical constains onsite, and hauling distances.

The type and condition of the soil is important when choosing the most adequate equipment since each piece of equipment has different outputs for different soils. Moreover, one excavation pit could have different soils at different stratums.  Larger volumes of excavation will require larger excavators, or smaller excavators in greater number.

Equipment characteristics

Type of equipment considered suitable for the task.

Make, models and size of special purpose, and general purpose equipment available that can handle the task

Production capability, serviceability condition and delivery time of each equipment available.

Economic considerations

Owning costs.

Operating costs

Re-sale or residual value after use

Replacement costs of existing equipment

Commercial considerations

Buy second – hand or new equipment

Rent equipment

Hire- purchase equipment

Purchase on lease.

Business School of the Future...Today's Architecture

Business School of the Future

The University at Albany in Albany, New York recently unveiled the architectural design for the new 96,000-square- foot, state-of-the-art School of Business building that evokes the style of its 1960s predecessor.


Designed by Perkins+Will, the building will feature technologically advanced classrooms and meeting spaces, break out rooms for team projects, expanded space for career services, student reception areas, collaborative research centers and additional graduate assistant workspace. It will have a trading room on the first floor with Bloomberg terminals.

The building's interior will have floor-to-floor terracing for maximum circulation and natural lighting, with an exterior represented by both solid and transparent volumes. Other features include including a glass overlooking a sunken garden that will serve as a gathering space for students and faculty. Also the expansive second-floor hall will be opened up with large skylights in the ceiling.. The building also includes a large second-floor hall with skylights at its ceiling.

Capital Gate, Abu Dhabi.

The Capital Gate building in the desert kingdom's capital, Abu Dhabi, has been certified by Guinness
World Records as the "World's Furthest Leaning Man-made Tower."
The 35-story Abu Dhabi building has an 18-degree slope, compared with four degrees for the freestanding bell tower.


But unlike the tower in Pisa, the Capital Gate building has been deliberately engineered to slant.




STRUCTURE
 
From its foundations right through its pinnacle, Capital Gate is a unique building and among the most technically challenging engineering projects in the world. Some key features stand out amongst others:



It’s gravity-defying 18 degree lean, widely believed to be the most inclined in the world The continuous twist of its form which ensures that the tower looks different from every angle The unique nature of the floor plate, each floor is uniqueThe foundation contains an incredibly dense  mesh of reinforced steel that sits above 490 piles, drilled 30 meters underground to accommodate gravitational, wind and seismic pressures.

The core of the building is a pre-cambered, ‘slanting’ core that pulls in the opposite direction to the lean.
 It straightens as the building grows, pulled into a vertical position by the change in the centre of gravity
of the building as concrete was poured onto subsequent floors.

The floor plates up to the 12th level are stacked vertically over one another. Between levels 12th and 29th the floor  plates stagger over each other, in relation to the lean and twist of the shell, by between 800 to 1400mm and then back to 900mm. Between the 29th storey and the top storey, the range is between 900 and 300mm in relation to the line of the façade.

Design


Nothing is standard about Capital Gate. Each room is different. Each pane of glass is different and every angle is different. It was designed to provide no symmetry so it inspires those within and outside the tower. Capital Gate was designed to be the most recognisable icon of the ADNEC/Capital Centre development. Further, it was designed to blend seamlessly with the National Day Grandstand, breathing new life into this historic  landmark for the UAE.
