信达地产，搞出大事儿了

Core Viewpoint - Residents of the Xinkangyuan community in Shanghai's Jing'an District are experiencing anxiety due to significant structural issues, particularly in Building 4, which has visible cracks attributed to ground subsidence [1][3][5]. Group 1: Structural Issues - The most severe issue is the visible cracks between the first step of Building 4 and the ground, with gaps measuring 10-20 centimeters, indicating ground subsidence [3][7]. - The property management attempted repairs, but the ground remains uneven, and similar issues have been reported in Building 2, suggesting widespread subsidence [5][9]. - A report from August indicated that the maximum subsidence for Building 4 and auxiliary structures was 2.84 mm, which has led to confidence from the developer, Xinda Real Estate, in denying responsibility [9][10]. Group 2: Construction Concerns - Residents suspect that the construction of the adjacent Xinda Xinanli project, located only 10 meters away, is responsible for the subsidence and resulting damage [5][9]. - The construction of a 16-meter deep foundation pit for the Xinanli project may have compromised surrounding ground stability, leading to the observed structural issues [9][10]. - There are concerns regarding the reliability of the third-party report on subsidence, as it may have been influenced by the interests of the paying party [9][10]. Group 3: Developer's Response - Xinda Real Estate has agreed to address safety concerns and provide compensatory repairs, but this does not resolve the underlying issues of potential ongoing subsidence [10]. - The local community committee is involved in facilitating communication between residents and the developer regarding the safety and repair measures [10].
