Due to the late start of real estate development in China, there is relatively little experience in delivering finished products for fine decoration of commercial residential buildings. At the same time, homeowners have high requirements for fine decoration delivery, and there is a situation of "making trouble every time" in some cities, which puts Chinese real estate development enterprises in a disadvantaged position in delivering fine decoration houses. How to strengthen the quality of interior decoration projects for commercial residential buildings and improve delivery satisfaction is an urgent problem that real estate enterprises are facing. Keywords: Fine decoration; Real estate; Quality control. 1. Overview of Delivery of Interior Fine Decoration in Commercial Residential Buildings With the increasing regulation of real estate by local governments in 2018 and the saturation of the internal market of the real estate industry, as a typical product of an "inward oriented economy," competition among real estate developers has become increasingly fierce. In order to enhance market competitiveness, real estate enterprises have begun to improve their competitiveness through the delivery of fine decoration of commercial residential buildings, utilizing centralized procurement costs. Therefore, the delivery of bulk refined decoration of commercial residential buildings has gradually become a trend in the real estate industry.[1] However, there are frequent reports of quality issues in the delivery of fine decoration for commercial residential buildings. The complaint rate of homebuyers towards the quality of fine decoration is gradually increasing, and rights protection activities related to fine decoration of commercial residential buildings are also frequently occurring. In 2018, there were particularly frequent rights protection activities for fine decoration of commercial residential buildings in Wuhan. The methods of rights protection were not limited to individual rights protection activities organized by different properties, but more than a hundred properties joined forces to protect the rights of fine decoration of commercial residential buildings. Due to the fact that the standards for high-end decoration houses built by real estate developers far fall short of the requirements of homebuyers,a large number of homebuyers have joined forces to demand that real estate developers refund the price of the fine decoration part of the commercial housing. At the 315 Evening Gala in 2020,a report exposed serious quality problems in the fine decorated real of a Guangzhou real estate enterprise. This report further highlights the issue of quality in the fine decoration of commercial residential properties, such as roof seepage and disorderly pipeline installation.[2] Therefore, as real estate enterprises gradually promote the delivery of fine decoration for commercial housing, how to control the quality of fine decoration for commercial housing is currently an urgent problem that real estate enterprises need to solve. 2. Key Points for Quality Control of Fine Decoration of Commercial Residential Buildings At present, various real estate enterprises have set up fine decoration control points that are suitable for their own enterprises and developed projects. After collecting the delivery situation of indoor fine decoration in the Chengdu market in recent years, the article divides the quality control points of indoor fine decoration of commercial residential buildings into four aspects: indoor space and water&electricity equipment, indoor decoration, doors& windows and railings, installation parts. The key points of various aspects of testing are as follows: 2.1. Key points for indoor space and water&electricity equipment inspection Detection site Key points of detection Entrance door ①Collision between door leaf and wall/ground/opening less than 90° ②Gap at the bottom of door leaf greater than 2cm ③Collision between handle and wall or parts after opening Indoor distribution box ①Short circuit and leakage test protection cannot be used normally ②Turn on the switch, and the corresponding circuit is not powered on Underfloor heating/radiator ①Abnormal switch opening and closing ②Leakage points in the underfloor heating collector, water distributor, and radiator 20 socket ①The grounding protection is ineffective ②It is not installed, and the circuit cannot be powered on due to faults ③The phase sequence test and short circuit protection test are abnormal ④Ordinary sockets should be set in the air conditioning position, and the splash proof cover plate should be set in a location that is not set (balcony washing machine position/bathroom) 2.2. Key points for indoor decoration inspection Detection site Key points of detection wood floor ①There are large and small ends in the paving, which are not square (greater than 1cm) ②Treading and collapsing, resulting in ash emission. ③Bulging, swelling, and blackening coating ①Paint penetration, uneven brushing, and repair of color differences ②Coating bulges and peeling ③Rough and uneven closing of the handover area ④The corners of the yin and yang are not straight or square Wall and floor tiles ①Hollow drum ②Gap height difference, damage ③Uneven gaps Stone ①Uneven and rough closing at the junction of different materials ②Poor mirror treatment and lack of brightness ③Stone alkali reaction and blackening Ceiling (including kitchen and bathroom) ①Wave pattern ②Deformation, paint peeling, rust spots ③Paint sagging ④Uneven buckle plates and uneven seams (in kitchen and bathroom) ⑤Uncleaned garbage in removable ceiling of bathroom, exposed wires ⑥Uncleaned construction garbage in light trough Skirting line (including all functional skirting lines) ①The non nail hole groove part of the skirting line is fixed with nails ②The width of the connection part with different materials is not consistent③The upper mouth of the skirting line is strictly prohibited from being repaired with putty 2.3.

Scoring Method to Obtain Weights A questionnaire was distributed to owners of recently delivered projects in Chengdu, and importance ratings were given to each testing site. The results are as follows: Detection site Weight (%) Detection site Weight (%) Indoor space and water and electricity equipment 15 Entrance door 58 Indoor distribution box 10 Underfloor heating/radiator 22 socket 10 Indoor decoration inspection 30 wood floor 26 coating 10 Wall and floor tiles 27 Stone 15 Ceiling (including kitchen and bathroom) 12 Skirting line (including all functional skirting lines) 10 Doors, windows, and railings 5 Indoor door 75 Railing 25 Installation component 50 Kitchen and bathroom cabinets 12 Kitchen countertop 11 water channel 7 Storage (wardrobe/foyer cabinet) 7 Toilet 15 Toilet basin/countertop 7 Shower screen/bathtub 15 Faucet/Shower 12 Air conditioning/fresh air 12 Floor drain 2 4. Conclusion and Outlook The article investigates the delivery situation of houses in the Chengdu market and identifies the quality control points for indoor fine decoration delivery in four aspects: indoor space and water&electricity equipment, indoor decoration, doors&windows and railings, and installation parts. The article also summarizes the testing points and methods. Later, 22 through the recent distribution of questionnaires to customers of delivered houses (fine decoration) in Chengdu, the weight of each testing part was identified. The article can be used for quality control of fine decoration in real estate enterprises, as well as inspection points for the delivery of fine decoration by homebuyers.
