Temporary Overlay Work
The Tokyo Organising Committee of the Olympic and Paralympic Games (Tokyo 2020 Organising Committee) will construct and install temporary overlay, including prefabricated units, tents, lighting for broadcasting purposes, spectator seating, security fencing and competition space, for eight new permanent competition venues, 22 existing competition venues, and nine temporary competition venues.
Details of temporary overlay work
Temporary overlay work can be largely separated into two main categories: architectural work and installation of equipment and amenities. Of the overall temporary overlay work required, 50 percent is architectural work, 30 percent is installation of equipment and amenities, while the remaining 20 percent consists of various other types of work.
Scale of temporary overlay work
Additional construction and installation of temporary infrastructure for the Tokyo 2020 Games includes prefabricated units and tents for Games operations purposes covering a total area of 300,000 square meters, lighting for broadcasting purposes at 25 different venues, 150,000 seats (spectator seating), 110 kilometres of security fencing, and Games competition space.
The estimated cost for the construction and installation of this temporary overlay is approx. 280 billion yen (separate budget for electric power supply).
