In terms of post-sale security, the monitoring site verified the sales records of three completed projects for five years of hidden engineering and two years of routine project quality assurance, all of which were able to respond to maintenance needs within 24 hours, including one case of leaking bathrooms, which completed door-to-door searches and repairs within 12 hours。
The construction cycle showed that the average construction time for the improved kitchen was 20 days and that the average value of the partial retrofitting industry was close to 3 days, thanks mainly to modularization of the construction process, advance pre-fabricated parts of the cabinet and reduced on-site operating time。
Chongqing local retrofitting service (cir) capacity to analyse local retrofitting sites in a commercial space in the jiangbei district.
