"Only half a year after the house was handed over, more than 300 owners in the community complained about the cracking of the house and bought a heart plug."
Recently, Huang Yu (a pseudonym), a citizen of Xichang, Sichuan Province, asked for help through the cover news national help reporting platform.

More than 300 owners' houses in the community have cracks of varying degrees.

In this regard, the developer Xichang Bangtai Real Estate Co., Ltd. entrusted a third-party testing company for appraisal. The identification results show that the cracking is mainly caused by the inconsistent shrinkage deformation of concrete materials and infill wall materials under the combined action of the external environment and temperature, which does not affect the safety of the main concrete structure. The site problem is a common engineering quality problem in the construction industry.
However, the owners of the community do not agree with this conclusion. On May 17, the cover reporter learned from the Xichang Construction Engineering Affairs Center that, in response to the owner's demands, the relevant departments will actively cooperate with the owner's representative and entrust a third-party housing safety appraisal agency to carry out the safety appraisal again.

"There are cracks on the wall and ground. We first reported to the property, but the developer only sent people to repair the problem, and even continued to crack after the repair." The owner representative of the community said that since the end of September last year, the owners found cracks in the house, including floor cracks and wall cracks, More than half of the houses in the community are registered to have cracks. "We asked the developers to identify the safety of the houses, and the developers said that the safety would not be affected after the identification. The cracks are still increasing, and they have been evading when they came to the developers later, which has now been pushed from March to May."

The appraisal results are as follows: the cracks in the floor slab are mainly caused by the concrete shrinkage, and the atmospheric temperature changes have a certain impact on the development and expansion of the cracks, which belong to the temperature shrinkage cracks, and there are cracks under no force, which does not affect the safety requirements of the slab under the design normal service load; Among the wall cracks, the vertical cracks at the interface between the concrete shear wall and the infilled wall in the living room and the interface joints between the structural column at the corner of the windowsill and the infilled wall of the windowsill are mainly caused by the inconsistent shrinkage and deformation of the concrete materials and the infilled wall materials under the combined action of the external environment and temperature, which belong to shrinkage cracks and non stress cracks, It does not affect the safety of the main concrete structure.

Official response
Relevant departments will organize housing safety inspection again
On April 25, in response to the previous complaints of the owners of the community on the platform of "asking politics in Sichuan", the Xichang Construction Engineering Affairs Center replied that the staff of the center went to the site on April 23 to verify that there were cracks of varying degrees on the middle wall of the living room wall, and organized the person in charge of the construction unit and the buyer's representative to coordinate. At the consultation meeting, the construction unit arranged the property company to register the households with problems one by one and report to the head office. After the May Day holiday, the construction unit negotiated the rectification process with the owner's representative again, and promised to rectify the relevant problems of each household according to the rectification plan reviewed and approved by the design unit.
It was mentioned in the reply that the Xichang Construction Engineering Affairs Center once urged the construction unit to entrust the qualified Sichuan Academy of Building Sciences Co., Ltd. to detect the cracks on the middle wall of the living room wall on April 10. The official report concluded that the cracks were caused by uneven shrinkage of different materials, which did not affect the safety of the main structure.

However, the owners of the community did not agree with the test conclusion, and questioned "how much wind and temperature difference can make more than 300 houses crack?"
Huang Yu said that the owners' representatives of the community had also consulted with the developers for many times, but no consensus was reached. "Now we want to make a new appraisal to understand the real security situation of the house; if it is safe, we hope the developer can compensate for the cracks in the house; if it is unsafe, we want to apply for compensation after returning the house."
On May 17, under the coordination of relevant local departments, the developer and the owner's representative of the community held another negotiation. On the same day, the reporter learned from the Xichang Construction Engineering Affairs Center that at present, Xichang has set up a special work team for this situation, and will actively cooperate with the owner's representative to entrust a third-party housing safety appraisal agency to carry out safety appraisal again. In addition, authoritative experts will be hired separately to conduct a comprehensive investigation and analysis of housing quality problems and analyze the causes.
