Architect Zaha Hadid has abandoned her attempt to enter a new race to build a new stadium in Tokyo for the 2020 Olympics and Paralympics, her office said Friday.

Zaha Hadid decided to withdraw from the new competition to design Tokyo’s Olympic Stadium. Her initial design for the new National Stadium was scrapped in July due to soaring construction costs. However, just a couple weeks ago the Iraqi architect assured her office would submit a new proposal in upcoming second competition.

Hadid’s office and Japanese construction consultancy company Nikken Sekkei Ltd., which had teamed up to enter the new race, said they “have not been able to secure a construction company in their consortium.”

The second competition for a new stadium design would be held within six months with plans to finish the stadium by spring 2020, according to the Wall Street Journal in July, which cited Japan’s sports minister.
