Temporary and modular seating solutions are the answer
to providing a wide range of stadia and facilities with
greater capacity and flexibility when hosting events
2014 Asian Games, Incheon
The Korean city of Incheon successfully hosted the
Asian Games in September 2014. The Main Stadium,
newly built for the Games, has 60,000 seats, with 32,000
rented seats as a prefabricated temporary structure.
The temporary seating at the stadium sat on the
inner concrete structures and an uneven surface, which
was the challenge that warranted high structural stability.
Unitech System has been working on these issues
throughout the project, from proposing a suitable design
to supplying and implementing the solution. In building
temporary seating units, it chose a unique truss system
instead of the more common scaffolding structure,
which offers a more stable design and a higher-quality
seating solution. It also carefully calculated the loads
several times over to ensure that its solution is both ideal
for the purpose and financially viable.
The prefabricated steel structure and aluminium
platform stays resilient against rusting for 20 years.
This structure comes with chairs that are resistant to
UV discoloration and made of high-strength plastic,
making them all the more suitable for outdoor use.
Following the Games, all of the prefabricated
temporary seats were removed. As the supplier,
Unitech used the same seats for other international
events as part of a mission to reduce the costs for
construction and maintenance while ensuring that the
space can be repurposed as a public park or a multipurpose
facility after the Games, which helps generate
revenue to help maintain the stadium.
Coinciding with this project, Unitech also provided
3,000 seats for the World Rowing Championships 2013
and 9,000 seats for a local festival at the same time
through quick installation of temporary seating and
relocation to other sites. This is a cost-effective solution
to our clients who often wish to organize large scale
events with a tight budget.
or large-scale sporting projects and events,
common seating options include telescopic
and fixed systems. However, prefabricated
temporary seating is one of the most
popular seating options due to its advantage
in large settings.
Grandstand seating manufacturer, Unitech System,
has been working on a number of projects since it was
established in 2002. It has been involved with largescale
sporting events to provide seating solutions. Its
temporary and telescopic seating offers an efficient
solution to maximise the number of available seats
in a multi-purpose space, and can be applied to stadia,
gymnasiums, auditoriums and one-off events at
2019 FINA Swimming
Championship, Gwangju, Korea
Unitech System built spectator seats for the swimming
arena and water polo pool, supplying 7,100 and 4,340
The project boasted a much larger scale compared
to those for ordinary modular grandstands. Seating at
the swimming arena was arranged into 42 rows and
at a height of 98ft (30m), while the water polo pool
stadium seats were arranged into 14 rows and at a
height of 36ft (11m). Both were made using a beam
truss structure and an aluminium platform.
The existing swimming facility did have spectator
seats, but only on one side of the venue. To offer a
larger seating area that can live up to the expectations
of the organizers and guests of an international sports
event, a wall was removed to install the 7,000
temporary seats and a membrane roof in its place.
This type of project usually takes six months-to-ayear
to finish, however, the process was completed
within just three months.
