Architects from the Beijing Institute of Architectural Design used a cable membrane construction and bricks of river ice to create this installation in Qinhuangdao, China, which has been shortlisted for a 2023 Dezeen Award.
A workforce from BIAD, led by architects Xiyan Yang, Guanjia Li and Chenzhi Yan, designed and constructed the Falling Hours pavilion to supply guests a ceremonial means of marking the flip of the yr.
Throughout 2022’s New Yr’s Eve celebrations, passersby have been invited to gather sand from the seashore within the coastal neighborhood of Aranya, the place the set up was constructed.
This sand was poured via a gap on prime of the construction, accumulating in its conical membrane roof, which successfully functioned as an enormous hourglass.
At midnight, contributors pulled on a ribbon to open this funnel, prompting the sand to rain onto the ground, whereas guests wrote their needs for the brand new yr on the hourglass membrane.
The venture drew on the same roofing system to the one which BIAD helped to engineer for Foster + Partners’ Lusail Stadium in Qatar.
However on this case, it consisted of a round metal construction with a diameter of six metres and a top of three metres, supported by a tensioned cable and membrane roof designed to bear the load of two tonnes of sand.
The cable membrane construction resembled a conical hourglass, with its forces anchored in a hoop beam across the perimeter and a pressurised spar on the centre.
“The centre of the hourglass is a pressurised gusset that holds up the roof and on the similar time holds up the membrane on the decrease finish of the spokes,” stated the venture workforce.
The decrease a part of the membrane consisted of a semi-transparent PTFE mesh laminate, whereas the roof masking the higher a part of the spokes was made utilizing an ETFE plastic that allowed mild to enter the inside.
Knowledgeable ice sculptors from the Harbin Ice Festival in Heilongjiang province created an outer wall across the metal framework utilizing river ice that was clear sufficient to be partially see-through.
The set up’s timing coincided with Qinhuangdao’s coldest season and the ice wall was designed to final for round a month earlier than step by step melting within the warming solar.
Sand from the seashore was used to fill the hourglass and was returned to the seashore as a part of the ceremony. BIAD says the metal construction was recycled and the membrane was used as an exhibit to protect the reminiscence of this one-off occasion.
Falling Hours has been shortlisted within the set up design class of this yr’s Dezeen Awards alongside the French pavilion at the Venice Architecture Biennale and a showcase of repaired objects at London’s V&A.
