Although they are probably the most neglected
forms of architecture, toll plazas form an important ‘every day’ space for
millions of people in cities. In an effort to redefine the design of toll plazas,
Archohm, has attempted to give toll plazas in India, an identity of their own.
With each new design, there is an attempt to create a new experience and
innovate with form.The initial two toll plazas being built by DS Constructions
were at the Delhi - Gurgaon border and a smaller plaza at the entry point to
Dwarka and the IGI international airport. These would be used by millions of commuters
every day travelling to Gurgaon, the upcoming commercial and residential hub of
NCR. Taking off from the client’s brief, ‘Give us our visiting card in the road
infrastructure’, Archohm set itself on a mission to design functional city and
urban spaces that would leave an impact on the city skyline.With sound prior experience in toll plazas,
Archohm defines the functions of a typical toll plaza with three distinct areas.The first is the plaza zone which comprises of
lanes, toll collection booths, an underground tunnel and an over-head canopy
which defines the toll plaza area and provides the required visibility to
approaching commuters.The second is the toll control zone, which begins with the ‘cash up’ area
at the end of the tunnel, a strong room and a money transfer facility to the
bank. These facilities are at the basement level with a ‘control room’ that oversees
the complete operations of the toll plaza. After several brainstorming sessions
between the Archohm design team headed by Mr. Sourabh Gupta and the tolling
team, headed by Mr Allen Le Roux, a comprehensive and holistic design was
achieved.The IGI toll plaza, was intended to be a high visibility plaza. Acting
as a gateway to the city for people flying into Delhi, nationally or
internationally, its design adheres to international standards. Comprising of
attractive and hi-tech frame less glass booths, a glass operations unit and a tensile
canopy structure that punctuates the compact plaza, this design is anything but
the usual.Today, the Delhi – Gurgaon toll plaza has been declared
the largest in Asia. With a twisted floating canopy that sits on seven 7.2 m
high pins of concrete, its form has been declared as a structural marvel. Architecturally,
the bottom of the canopy is lit with changing colored LEDs that allow the daily
commuter to undergo varied visual experiences.Another iconic feature of this project is the
roof of the administration block which doubles up as a parking. Being
associated with flyovers and highways and addressing issues of space
constraints and security, the rooftop parking creates an out of the ordinary statement.
From the surreal aesthetic of seeing the cars parked on the roof, to giving
people a strategic deck to enjoy the plaza view, this toll plaza design has
helped Indian transport architecture graduate to the next level!A plaza
of this nature and scale gave Archohm an excellent opportunity to play and
experiment with urban street lighting in modern city life and show off the ‘power
of power’.The canopy
provides shade as well as keeps the structure light and minimal in design.
Specialized lighting seeps through the fabric enhancing the structural
aesthetics and bringing a sense of dynamism in form and surface.Colour
renderings through changing LED systems provide the canopy with an iconic sense
that is distinctly visible, when approaching from a distance. The all- white
vocabulary of the plaza is in line with the entire urban color scheme of the
expressway, with its slick white streetlights
and reflectors.The IGI
toll plaza was built in record time of six months, marking a new design and
engineering trend in Indian toll plaza construction.
