The document describes the Science City complex in Kolkata, India. It is divided into zones for public, semi-public, and private areas. The centerpiece is the Dynamotion hall, a 38-meter high ziggarat structure housing a display of rolling balls demonstrating physics principles. Lighting comes primarily from a central skylight, with additional fluorescent and halogen lights. The complex aims to educate visitors through interactive exhibits while maintaining clear circulation routes. Overall the document provides an overview of the layout and design of the Science City complex.

1. Introduction-:
• The science city was conceived by the National Council of science museum and its first of its kind of an
educative and entertainment park set up in India.
• The site is located at the junction of eastern metropolitan bye pass and park circus connector with ITC
Shonar Bangla Sheraton and towers in the front and energy park on its eastern side.
• Almost a rectangular shaped site is formed on the barren garbage dump land with degraded soil on top 6m
layer of the site.
• Architects- Development Consultants pvt. Ltd.
• Completed- 1997
Zones-:
The complex is divided into the following zones:
1. Public:
• Gate Complex- 1352 sqm.
• Space Odyssey Hall and Dynamotion- 9200 sqm.
2. Semi Public:
• Convention Centre- 23117 sqm.
• Main Auditorium- 2232 sitting capacity
• Mini Auditorium- 392 sitting capacity
• Seminar Halls- 6 in number
3. Private:
• Administrative Areas
• Service Areas
One entry is from the Park Circus- East
Metropolitan Bye Pass
The secondary entrance leads to the Gate Complex of
Science City through a landscaped plaza and the other
to the convention center.
The internal roads are 15m wide to the
entrance and the parking.
An internal lane 7.5m
wide forms a loop
around the site and exits
at the rear gate.
Parking is available for 500 cars and 5 buses.
A network of sandstone
paved lanes connect the
various buildings on site.
Built and Open Space Relationship:
F.A.R. provided- 0.34
Ground coverage provided- 16.62% i.e. 33426.38 sqm
Total built up area provided- 68,284 sqm.

2. Architectural Form-:
A variety of shapes is chosen for different blocks gives each block a separate identity but does not complement the site.
The domical form of the space Odyssey and the descending spiral of the Dynamotion hall resemble a massive ziggurat.
The convention centre is in the form of two split spheroids depicting a titled saucer and a huge truncated spherical cone
rising one behind the other.

The science park is square in nature.

3. Dynamotion
• The word Dynamotion is derived from dynamic motion.
• It is a structure that houses a 28 meter high exhibit called the rolling ball which shows the dynamics of a
large number of rolling balls moving in different trajectories proposed by mechanical, pneumatic and
hydraulic forces to demonstrate various aspects of physics in a fascinating manner.
• It is 38 meter high structure with a spiral shaped ramp around a central atrium.
• The form is a ‘Ziggurat’ 38m high with a spiral shaped ramp around the center.
Architectural Form:
The descending spiral of the Dynamotion hall resemble a massive ziggurat.
It is planned as inward looking building with a closed atrium.

4. •The central atrium houses the exhibit.
•The ramp around the atrium allows a continuous
view of the Rolling Balls from all directions at all
levels.
•The atrium and ramp create a transparent interior
space which is visually connected at all levels:
making the space more active and dynamic.
The hall has two symmetrically placed galleries to
the longitudinal axis of the building containing insect
model displays and water based experiments and
exhibits. Opposite corner of the rectangular hall
have services rooms such as electrical room and
store.
The ground level plan consists of a
huge 5 storey descending atrium;
containing a huge energy conservation
ball display rising up to the full height of
the atrium with water exhibits at the
base.
 The ramped gallery contains exhibits like illusions, world of insects and
fishes on the left hand side of the ramp for convenient watching.
 The outer wall of the ramp is used as display area for various displays.
The continuous display of the energy ball in the center appears to the right of the visitor in
whole journey to the podium level of 4.96m.
Fire escape ramp having slope of 1:12 runs parallel to the main ramp and ends with
staircase to the podium and then 2 staircases from podium to the ground.
Right opposite to the entry, two 16 passenger lifts
takes you up to the top level of 24.6m high ramp.
From here a visitor descends his journey down on
a spiral ramp 4.5m wide ramped gallery.
Dynamotion Floor Plan-:
• Structure system is bulk active.
• The complete structure is supported on two non concentric rows of 16 columns each on a spiral base.
• The top of the atrium is together with steel joists and glass on the top for provision of light.
• The structure is finished with stone grit all around.
Structure and Material-:

5. Circulation-:
• The circulation pattern offers a memorable experience inside the minds of general visitors and imparts a clear sequential character of the building.
• Unidirectional flow of visitors is maintained from entry to exit.
• The exit to the main building is through the staircase which leads the passenger to the ground from the 1st
floor.
• The ramp is 38 m high spiral shaped and 4.5 m wide.
• The spiral ramp provides uninterrupted view of ‘Rolling Balls’ at all levels and sides.
• Service entry is common with the visitors entry and in the ramp it continues on the outer ramp.

ascending circulation ramp 5’-0” wide is followed throughout
the exhibition area.
The terrace provides a breathtaking
view of the surrounding landscape.
Once the visitors has viewed the ground floor exhibits; he takes the
elevator to the top floor at a level of 24.6 m.

6. • As the major buildings are exhibition spaces, so lighting needs to be carefully analyzed to meet the requirements of these spaces.
• A large expense of natural lighting provided from the central atrium by a steel and glass sky light which gives a glare free and enough lights to lit the whole building. However,
deeper areas and galleries especially insects and aquarium are provided with fluorescent tubes and halogen lights wherever required.
• Due to the inward looking, demand of enclosed nature and giving the outer façade of the building a window free surface due to extra ordinary forms. A system of lights that is
followed is:
Skylights:-
Provided in the central lobby which connects the Dynamotion hall and the space odyssey and hence lights the
whole area with blue light.
A skylight is also provided in the main atrium of the Dynamotion hall which avoids the wastage of displaying area
and lit the whole building.
Artificial Lighting:-
Done by fluorescent tubes in the halls.
Further the exhibits are provided with fluorescent tubes and halogen lights.
Structural Glazing:-
The ramp in the Dynamotion hall is lit with structural glazing provided at various distances which
provides glare free light and also serves as a point for the overall view of the science city.`
Lighting-:
•These methods of lighting not only lit the interiors but also provide a sense of openness within the building.
•The skylight in the buffer zone provides ample light to the common entrance of the Odyssey and Dynamotion
