5,000㎡ Renovation Project of Shenyang Railway Station West Rolling Stock Depot

Case Background
As a core supporting facility for railway transportation, Shenyang Railway Station West Rolling Stock Depot undertakes important functions such as train inspection and maintenance. Its architectural appearance is not only related to the overall image of the railway hub but also needs to take into account durability, stain resistance and safety in industrial scenarios. After long-term use, the exterior facade of the existing buildings in the rolling stock depot has experienced problems such as fading, damage and weathering, which not only affect the appearance but also pose certain safety hazards. To improve the overall style of the rolling stock depot and extend the service life of the buildings, the customer launched a 5,000-square-meter renovation project for the exterior facade of the buildings, clearly selecting real stone paint as the core coating material. It is required to balance decorativeness, durability and adaptability to industrial scenarios, while ensuring efficient project construction and stable delivery. With rich experience in industrial building renovation and full-process service capabilities, we successfully undertook the project, providing one-stop services from sample confirmation, on-site construction guidance to production and delivery, and finally obtained high recognition from the customer.

Core Customer Needs
Combined with the industrial attributes and renovation needs of Shenyang Railway Station West Rolling Stock Depot, the customer put forward the following core demands, providing clear guidance for the project service direction:
•Decorative Demand: The real stone paint coating effect should fit the solemn and clean style of railway facilities, with uniform color, natural texture, restore the texture of natural stone, improve the overall appearance grade of the rolling stock depot, and be coordinated with the surrounding railway hub environment.
•Durability Demand: The rolling stock depot is a high-frequency operation area. The wall surface needs to withstand sun and rain, industrial dust erosion, slight collision, etc. It is required that the real stone paint has excellent weather resistance, stain resistance and wear resistance, avoiding fading, peeling, falling off and other problems in a short period of time, and extending the service life of the renovated wall surface.
•Service Guarantee Demand: The project construction should take into account the normal operation of the rolling stock depot, avoid affecting the core work such as train inspection and maintenance, and require standardized and efficient construction processes; at the same time, it is necessary to provide full-process services from sample confirmation to production and delivery, ensuring stable material quality, standard construction technology and full-process controllability.
•Compliance Demand: The real stone paint materials used should meet national environmental protection standards, without pungent odor and harmful volatilization, adapt to the environmental protection requirements of industrial buildings, and the construction technology should comply with the relevant specifications for railway facility renovation to ensure construction safety and project quality.

Full-Process Service Implementation Plan
In response to the core needs of the customer, we have established a full-process service system of "sample first, construction escort, stable delivery", focusing on every key link of real stone paint application to ensure the high-quality implementation of the project. The specific implementation plan is as follows:

(I) Sample Confirmation: Accurate Matching to Lay the Foundation for Quality
Sample confirmation is the primary link in the control of real stone paint coating effect and quality. We strictly follow the principle of "sample guidance, construction after acceptance" to ensure that the final coating effect meets the customer's expectations. First of all, combined with the industrial attributes of the rolling stock depot and the customer's aesthetic needs, we selected suitable types of real stone paint, carefully selected natural colored sand and high weather-resistant emulsion, and provided a variety of sample schemes with different colors and textures for the customer to compare and choose. Secondly, according to the standard construction process, we made samples of 800*800mm specification, completely presenting the full-process section from base treatment to topcoat protection, and clarifying the real stone paint application rate (controlled at 2.5-3.0kg/㎡) to ensure that the sample effect is consistent with the actual construction. Finally, we organized the customer and design representatives to participate in the sample acceptance together, checked the key indicators such as color, texture and adhesion one by one, patiently answered the customer's questions, and made fine adjustments and optimizations according to the customer's feedback until a consensus was reached. A sample confirmation form was signed to set the standard for the subsequent large-area construction, avoiding rework and shutdown caused by inconsistent samples and reducing project costs.

(II) On-Site Construction Guidance: Standardized Construction to Ensure Project Quality
Considering the particularity of the rolling stock depot's operation and the professionalism of real stone paint construction, we set up a professional technical guidance team to provide one-on-one on-site construction guidance throughout the whole process, ensuring standardized construction processes and up-to-standard technology, while minimizing the impact on the normal operation of the rolling stock depot.

Before construction, the guidance team conducted special training for construction personnel, detailedly explaining the key points of real stone paint construction technology, safety specifications and precautions, focusing on the operation standards of key processes such as base treatment, primer brushing, real stone paint spraying and topcoat protection. During the construction process, in strict accordance with the sample standards and construction specifications, we supervised every process throughout the whole process: in the base treatment stage, we guided the construction personnel to clean the floating dust and oil on the wall with high-pressure water guns, and repair the weathered, hollow and cracked parts with waterproof and anti-crack mortar to ensure that the base is flat and firm, laying the foundation for the adhesion of real stone paint. In the primer brushing stage, we controlled the uniformity of brushing, avoided missing brushing and sagging, and enhanced the adhesion between the base and real stone paint. In the real stone paint spraying stage, we guided the construction personnel to control the spraying thickness and uniformity, ensuring uniform color, natural texture, restoring the texture of natural stone, and avoiding sagging, pinholes and other problems. In the topcoat protection stage, we selected high weather-resistant topcoat agent, brushed it evenly, improved the stain resistance and weather resistance of the wall, and extended the service life.

At the same time, combined with the operation arrangement of the rolling stock depot, we reasonably planned the construction area and construction time, adopted the phased construction mode, avoided the peak period of train inspection, did a good job in the protection of the construction area, prevented construction dust and material pollution from affecting the normal operation of the rolling stock depot, and realized non-interference between construction and operation.

(III) Production and Delivery: Stable and Efficient to Ensure Project Progress
The stable supply of real stone paint materials is the core guarantee for the project to be completed on schedule. Relying on the standardized production base and improved supply chain system, we have realized full-process controllability of material production, testing and delivery. In the production stage, in strict accordance with the formula standards confirmed by the samples, we selected high-quality raw materials and adopted standardized production processes to ensure that the color, texture and performance of each batch of real stone paint are consistent. At the same time, we established a strict quality inspection system to test the adhesion, weather resistance, stain resistance and other indicators of each batch of products. Unqualified products are resolutely not allowed to leave the factory to ensure stable material quality.
In the delivery stage, combined with the construction progress, we formulated a precise delivery plan and adopted a special vehicle delivery mode to ensure that the real stone paint materials are delivered to the construction site on time and in quantity, avoiding the impact on the construction progress due to material shortage. At the same time, we arranged special personnel to connect with the delivery matters, check the quantity and specifications of materials, and provide relevant materials such as product test reports and certificates of conformity to ensure the standardized and efficient delivery process and provide guarantee for the smooth progress of construction.
