If you read the Chinese text, it did say that they had to dismantle certain structure because it is blocking the fire truck. And it explain those are entrance and exit gate and railings for traffic control of vehicle moving in and out of the compound. It also say they have to remove some concrete block because of the large turning radius of the firetruck.
It is specifically the forth question that the gov't answer or the last 2 paragraphs.
Additionally I also read from weibo that some are mentioning vehicles blocking the road because of illegal parking, and it took sometime to remove them probably because difficulty in finding the resident owner in the building, some even mention vehicle not being able to start, but this is not mentioned in the report so I don't know how true.
