Water cube (beijing national aquatic center)

Water cube 

 Inside view of Beijing national aquatic center in 2008

   The national aquatic center also known as a water cube and beijing national aquatics center.

    That stadium for the swimming compitition of the 2008 summmer olympic. The building is a not actual cube but a cubical(rectangular box). After 2008 olympic turn half of its interior into water park and 8 august 2010 in reopened.

Building knowledge 

 Full name-  beijing national aquatic center

 City- beijing china

Open- 2008

Cons. Cost- USD$140million

Architect- PTW architects

                   CSCEC

                    CCDI

                    Arup group limited

Length of pool- 50m(160ft)

Width of pool- 25m(82ft)

Depth of pool- 3m(9.8ft)

New perspective about that building

- Enclosed within bubble walls are five swimming pools

- restaurants and seating for 17,000 spectators that are somthing more about other 

- that appearance(look design) are soap bubble type.

- in that facad method was Ethyl tetrofluoroethylene (ETFE) are choose  that are there benefits are

    1) on the 1% of glass weight 

    2) better thermal insulator

    3) save 55% lighting energy at daylight

    4) 30% energy consumption resuced in                total

    5) 20% solar energy is trapped and used              for heating.

- that are most seismicall resistant building in the world.

After 2008 olympic use  half portion as a water park

what is the Modular construction ?

Modular Construction

• What is the modular construction?

                   ‘Modular construction’ is a use of pre-engineered building units that are delivered to site and assembled as large volumetric components of a building. The modular units may form complete rooms, parts of rooms, or separate highly serviced units such as toilets or lifts. 

      

                  Modular construction is increasingly popular where a building is constructed off-site using the same materials and designed to the same standards as conventional on-site construction. It limits environmental disruption, delivering components as and when needed, and turning construction into a logistics exercise.

• where are they used?

            Modular buildings may be used for long-term, temporary or permanent facilities, such as construction camps, schools and classrooms, civilian and military housing, and industrial facilities. Modular buildings are used in remote and rural areas where conventional construction may not be reasonable or possible, for example, the Halley VI accommodation pods used for a BAS Antarctic expedition.^[2] Other uses have included churches, health care facilities, sales and retail offices, fast food restaurants and cruise ship construction. 

• Benefits of modular construction?

1. Rapid installation on site (6-8 units per day)
2. Economy of scale through repetitive manufacture
3. Low self weight leading to foundation savings
4. High level of quality control in factory production
5. Limited disruption in the vicinity of the construction site
6. Useful in building renovation projects, such as roof top extensions
7. Excellent acoustic insulation due to double layer construction
8. Adaptable for future extensions, and ability to be dismantled easily and moved if required
9. Stability of tall buildings can be provided by a braced steel core.
10. low waste construction.
11. environment friendly construction process.

• Application of modular construction

1. Suitable for buildings with multiple repeated units
2. Size of units is limited by transport (3.6m x 8m is typical)
3. Open sided units can be created (by changing the floor orientation)
4. Modules are stacked with usually no independent structure
5. Self weight of 1.5 to 2 kN/m²
6. 4 to 10 storeys (6 is usually the optimum)
7. Fire resistance of 30 to 60 minutes provided
8. Acoustic insulation is provided through double layer walls and floors.

•  Types of modular construction

1. 4-sided modules
2. Partially open-sided modules
3. Open-sided (corner-supported) modules
4. Modules supported by a primary structural frame
5. Non-load bearing modules
6. Mixed modules and planar floor cassettes
7. Special stair or lift modules.
