Jiangsu Action Plan for 2025 (Jiangsu Provincial Department of Housing and Urban-Rural Development)

　　The construction industry is a pillar, a competitive edge, and a wealth-creating sector for Jiangsu Province. Under the high attention and correct leadership of the provincial Party committee and provincial government, the province’s construction industry has set the goal of building itself into a “strong construction province,” vigorously promoting the modernization of the construction sector, accelerating the pace of industrial restructuring, and intensifying efforts to develop both domestic and international markets, thereby achieving remarkable accomplishments. At the same time, the development of our province’s construction industry also faces growing challenges such as increasingly tight resource constraints and an increasingly severe environmental protection situation. The industry still suffers from numerous problems and shortcomings, including extensive development approaches, low production efficiency, inefficient resource utilization, and insufficient capacity for scientific and technological innovation. Today, the rise of the information wave and breakthroughs in a series of widely applicable key technologies have created new conditions and opportunities for the industry. As the application of the Internet and digital technologies continues to accelerate and penetrate various sectors, industry boundaries are becoming increasingly blurred, and cross-sector integration has emerged as a major trend driving the next round of industrial upgrading. In response to the “Made in China 2025” strategy, Jiangsu’s construction industry should actively seize development opportunities, driven by new demands and supported by new technologies and platforms, while leveraging the mutual penetration, integration, and fission of diverse resource elements—including manufacturing and the information industry—to achieve extension and breakthroughs in the industry’s value chain.

　　The “Jiangsu Construction 2025 Action Plan,” based on an in-depth investigation and study of the province’s actual conditions and industry development trends, adheres to a demand-oriented approach and promotes reform and innovation. It outlines the innovative directions and development strategies for engineering construction methods in Jiangsu’s construction industry over the coming period—namely, driving the integration of “four modernizations” in engineering construction: refinement, informatization, greenness, and industrialization. The plan vigorously promotes four new construction approaches—lean construction[1], digital construction[2], green construction[3], and prefabricated construction—and gradually expands their application to key areas such as residential buildings and municipal infrastructure projects. This will foster the healthy and sustainable development of the industry and help Jiangsu maintain its leading position nationwide in the construction sector.

　　Drawing on mature practices of lean construction both domestically and internationally, we will promote and popularize the relevant concepts of lean construction, ensuring that all stakeholders fully recognize that lean construction represents an inevitable trend in the transformation of construction methods. In light of the actual development of the construction industry across the province, we will actively guide enterprises to shift away from their traditional, low-efficiency, high-energy-consumption development model, and commit themselves to minimizing waste throughout the entire construction process, achieving superior product quality, and maximizing customer value. We will organize resources to conduct in-depth research into the core theories and key technologies of lean construction, and provide tailored guidance based on the specific conditions of regions, industries, and individual enterprises. We will also carry out assessments of enterprises’ maturity levels in lean construction and, through pilot demonstrations and other approaches, gradually promote the scaled-up development of lean construction.

　　2. Guide enterprises in establishing a standard system based on lean construction.

　　Guide enterprises to establish a lean construction management standard system tailored to their own development, covering process flows, management procedures, operational standards, enterprise quotas, detailed design, and node standards.

　　Promote precise design. Guide enterprises to refine, supplement, and detail the original construction drawings by integrating enterprise standards and construction process procedures on the basis of traditional design. Through precise design, achieve accurate construction—including the proper reservation and pre-embedding of components—and enhance the scientific nature and rationality of construction operations, thereby establishing a comprehensive system of enterprise design standards.

　　Promote the rational division of work processes. Popularize modularization of process segmentation, using the Work Breakdown Structure (WBS) to decompose all stages of project implementation into smaller, more manageable process-level modules. By refining and standardizing these processes, we can achieve standardized operations. While adhering to national and local standards and regulations, we will integrate corporate culture, processes, and standards to establish a process-level standard system covering both operational and management levels.

　　Promote process briefing and streamlined operations. Guide enterprises to conduct thorough process briefings in areas such as safety, quality, and schedule, thereby enhancing pre-, during-, and post-event controls and establishing a formalized process-briefing system. Encourage enterprises, based on the rational division of processes, to achieve streamlined operations at construction sites through scientifically optimized process combinations.

Specifically, promote the use of value process maps—diagrams that depict the flow of work, information, funds, materials, and human resources for a given project—to conduct comprehensive value analysis across all stages of project construction. Strive to minimize waste and maximize user value.

　　Promote the establishment of a planning and control system. Actively encourage enterprises to set up a rational planning and control system during the construction phase, integrating logistics, cash flow, and information flow into the work processes to comprehensively enhance the precision of operations. Focus on promoting the Last Planner System (LPS), which, through decentralization of authority, enables operational personnel to develop the most appropriate work plans for engineering projects based on site resource and environmental conditions, thereby optimizing workflows and achieving zero schedule delays and zero quality defects in projects.

　　Promote just-in-time production. By implementing refined workflows based on the planned control system, we can minimize project waiting times and material stockpiling periods, thereby achieving just-in-time production. We will place particular emphasis on promoting pull-based production, where each process is driven backward from downstream to upstream according to actual demand, ensuring that products are delivered on time and in the right quantities. This approach eliminates the material buildup and time delays inherent in traditional production processes. We will also foster team collaboration based on concurrent engineering, enhancing coordination among construction work areas, reducing human-induced uncertainties and conflicts, and maximizing the assurance of zero handover delays and zero material backlogs.

　　Promote the “5S” [8] management approach. Guide enterprises to divide construction sites into designated areas, categorize and organize materials and items, establish reasonable storage locations, and clearly mark and label them. Conduct regular cleaning and sanitation of the site; promptly clean up and tidy up work areas for each process; enhance the professional competence of on-site personnel; strengthen management of partners and suppliers to ensure timely and quality deliveries; and make rational use of relevant information provided during the handover between processes, thereby laying a solid foundation for the smooth flow of subsequent processes and the overall construction workflow.

　　[1] Lean Construction is a comprehensive production management theory that involves fully applying the principles of “Lean Production” (originating from Toyota Motor Corporation in Japan) to construction projects. It is a systematic approach that focuses on the entire lifecycle of construction products, continuously reducing and eliminating waste while maximizing the fulfillment of customer requirements, thereby maximizing value throughout the entire construction process.

　　[2] Digital Construction: Generally refers to the integration of new information technologies such as BIM, big data, and the Internet of Things, leveraging various information management platforms to achieve digitalization of the construction process.

　　[3] Green Construction: Integrating green, energy-saving, and environmentally friendly principles throughout the entire lifecycle of a project—from design and construction to operation and maintenance—thus achieving green development in engineering construction. This article focuses on green construction practices and green building materials.

　　[4] BIM: Building Information Modeling is an engineering data model based on 3D digital technology that integrates various relevant information about construction projects. It provides a digital representation of the physical and functional characteristics of project facilities. This model can link data, processes, and resources across different phases of a building project’s lifecycle, offering real-time engineering data that can be automatically calculated, queried, combined, and decomposed. It can be widely used by all parties involved in construction projects.

　　[5] Digital Construction Site: By leveraging technologies such as BIM, VR, and AR, digital models of construction objects—including buildings and construction sites—are established. Moreover, attribute and temporal information elements are input into these digital models, thereby achieving digitalization of the construction site.

　　[6] Work Breakdown Structure (WBS): A method of grouping project elements around deliverables, whereby a project is decomposed according to certain principles. The decomposition process can be carried out in a top-down manner: the project is broken down into tasks, tasks are further decomposed into specific activities, and these specific activities are then assigned to individual team members. The level of detail in WBS decomposition can be determined based on the characteristics of the engineering and technical system as well as the requirements for control and management. Because this approach allows project work to be defined at an appropriate level of detail, it helps in making accurate estimates of project duration, costs, and resource requirements.

　　[7] Last-Level Planner System (LPS): This system emphasizes decentralization. The lowest level of traditional planning—such as construction teams—develops short-term construction schedules that fully take into account site-specific constraints and make the most rational work arrangements.

　　[8] “5S”: An abbreviation in Japanese for five words: SEIRI (Sort), SEITION (Set in order), SEISO (Shine), SEIKETSU (Standardize), and SHITSUKE (Self-discipline).

　　[9] Collaborative Management: A management theoretical framework that primarily involves the rational arrangement and combination of individual forces to accomplish specific tasks and projects. Its goal is to achieve synergy in information, business processes, and resources.
