Group 1 - The giant white dome in Jinan, Shandong, is a "gas-supported foundation membrane" designed to minimize dust and noise during the construction of a large commercial complex [4][2] - The dome, approximately 50 meters high and covering an area equivalent to 2.5 football fields, can block 90% of dust and reduce construction noise by 80% [4] - The dome's structure allows for a spacious interior without the need for load-bearing beams or columns, facilitating the entry of large construction machinery [6] Group 2 - The internal control system of the dome continuously monitors air pressure and temperature, ensuring a safe working environment [9] - The membrane material used is PVDF (polyvinylidene fluoride), which blocks 90% of UV rays and has a high thermal reflectivity and dissipation rate, along with a B1 fire rating [9] - After the project completion, the dome will be dismantled, but this eco-friendly construction model is expected to be promoted in municipal engineering and historical district renovations in Jinan [11]
