Removable steel piles will be driven into the ground with reused pipeline incorporated to reduce the need for new materials.
The result is that the temporary structure will touch the ground much more lightly than if the venue was conventionally built.
The venue in southeast London will host the Shooting and Paralympic Shooting competitions, in addition to Paralympic Archery.
Sisk is set to complete the site ahead of international shooting test events next spring.
ODA Project Sponsor for the Shooting venue, Richard Arnold, said: “The Shooting venue is the ODA’s final venue to start construction and will be ready to host test events next year.”
Immediately after the Games, the venue will be dismantled as quickly as possible and the site returned to its original condition, after which it will be handed back to the Ministry of Defence.
