沙特：拟建2000米高塔

Core Viewpoint - Saudi Arabia is planning to construct the Rise Tower in Riyadh, which aims to become the tallest building in the world, exceeding the height of the Burj Khalifa by more than double and the Shanghai Tower by three times [1][5]. Group 1: Project Overview - The Rise Tower is part of Saudi Arabia's "Project Rise - Lumenis," which aligns with the country's Vision 2030 strategy aimed at economic diversification and reducing oil dependency [5]. - The project is supported by the Public Investment Fund (PIF) and is estimated to cost around $5 billion, making it one of the most notable projects in PIF's expanding portfolio [6]. Group 2: Architectural and Engineering Challenges - The Rise Tower will face significant engineering challenges, particularly in ensuring efficient vertical transportation for its height of 2,000 meters, as traditional elevator systems are inadequate [9]. - Innovative solutions such as magnetic levitation elevators and multi-car designs are being explored to enhance passenger capacity and efficiency [9]. - The building's design must also address environmental challenges posed by Riyadh's desert climate, including extreme temperature variations and occasional sandstorms [10]. Group 3: Urban Development and Sustainability - The Rise Tower will be a key landmark in the newly planned "Arctic" district of Riyadh, which is part of a broader vision for a sustainable and technologically advanced urban environment [7][8]. - The concept of the tower includes a "vertical city" that integrates residential, commercial, and recreational spaces, contributing to the transformation of Riyadh into a leading global city [8][10].
