Future BIM will be applied in combination with lean construction

Introduction of BIM (Building Information Modeling) technology we are already familiar with, its main features include visualization, coordination, simulation and optimization. Lean construction is the application of lean concepts and its technical means in the construction industry, applied in the construction of a new production management, focusing on the "lean thinking" and the practical combination of the construction industry, in order to minimize waste, while creating the greatest value for the customer, lean construction and BIM are to reduce waste, improve efficiency, and create more value for the project. Lean construction and BIM are both concepts and construction methods aimed at reducing waste, improving efficiency, and creating more value for the project, and it can be said that the core concepts of BIM and lean construction are similar.

1, BIM for pulling just-in-time to provide synergistic "construction Kanban"

BIM visualization, simulation characteristics of the project planning and implementation stage, to provide the full production elements of the presentation and management of the operation Kanban, to improve the synergy of the project all parties involved. efficiency of all parties involved in the project.

Project schedule planning, project implementation, project processes before the operation, based on the BIM virtual construction pull supporting resource plan input, while verifying the rationality of the plan, timely optimization of the management of multi-disciplinary collaboration between the force, including technology, business, materials, labor, quality and safety, machinery and equipment, and other areas, the plan to pull the standardization of the task to meet the requirements of the task in the latter sequence, thereby achieving The latter task pulls the former task to maximize the value;

During the construction process, the actual progress of the project is fed back to the BIM model in a timely and punctual manner, and the project management can clearly grasp the current progress in real time whether there is any progress deviation, and the handling process of the problem to be solved, and at the same time organize each construction link in a punctual manner, so as to make the construction work process proceed in an orderly manner, and seek to achieve the state of zero interval, without delay or delay, and also to achieve the state of zero interval, without delay or delay.

BIM comprehensive planning simulation is value-driven, realizing the process, process and value of the work task, through a comprehensive planning control system, oriented to customer demand, to realize the pull type, Just-in-time comprehensive lean production management, thus realizing efficient teamwork, improving work efficiency, and reducing waste in unnecessary links.

Efficient flow of information and resource **** enjoyment is the prerequisite for the application of the last planner technology, BIM

technology provides an information platform and technical support for the promotion of the last planner technology, which will greatly improve the operability of the last planner's plan, and at the same time, the BIM

technology can realize the dynamic management of the resource and construction simulation, and y execute the last planner's pull process.

2, BIM for teamwork to provide a collaborative platform

Lean construction requires all the units and personnel involved in the project into the whole process of project management, comprehensive and efficient coordination of the relationship between the main body of the work is also an important work, lean construction to deal with the relationship between the various parties involved in the use of teamwork, teamwork Lean construction uses teamwork to deal with the relationship between the various parties involved, and teamwork should have a collaborative office, no information silos, project collaboration and personnel information *** enjoy the operating platform, and based on the BIM

technology is just such a working platform, BIM technology through the "cloud, big things, mobile intelligence" and other technologies combined to provide an efficient teamwork for teamwork, and at the same time BIM

Technology can be a project of the various divisions, sub-projects, workflow, and even each step of the process into the BIM

model, the application of this BIM has become an important collaborative platform and tools for teamwork applications.

3, BIM for parallel engineering efficient landing

Parallel engineering, as the name suggests, is from the beginning of the project planning to take into account the whole process of project construction of all phases of the management factors, BIM technology as a carrier of information integration, can be integrated into the construction process of the project of all kinds of production and management information, based on the BIM information management platform. The BIM-based information management platform can conveniently allow all project participants to collect, process, analyze and optimize the information related to the construction process.

So BIM can provide an information management platform for the implementation of parallel projects, which enables reasonable, necessary and effective information exchange between departments, and effective information can be fed back to the management platform in a timely manner, so that all project participants can have real-time control over the project development, and a lot of work can be carried out simultaneously to improve the efficiency and greatly shorten the project cycle.

At the same time, BIM also provides technical support for the implementation of parallel engineering, construction simulation, optimization of construction programs, work instructions, change management, quality and safety control and cost control during the construction phase, in order to pursue project management to achieve the purpose of zero waste, zero defects, zero accidents, zero pollution and other management objectives.

4, the synergistic application of total quality management and BIM

Through the BIM model as a carrier, the integration of different levels of quality control standards, construction process requirements, acceptance criteria and other regulatory documents, to provide an important reference for the process of quality control. The quality management objectives of each stage of construction correspond to the pulling control plan at different levels, which can be presented in Kanban management, so that the managers and operators have a clear understanding of the daily tasks;

BIM-based Kanban management provides an efficient and collaborative platform for the quality control of the construction process of the whole project, and constantly narrows down the quality control through the strict control of the whole project on each link, and improves the quality standard requirements. The scope of quality control and improve the requirements of quality standards, so that quality control personnel in different stages responsible for the development of different quality plans, construction process monitoring, acceptance of part of the project and other links, to strengthen the collaboration and communication between the heads of the various business areas, is committed to the overall quality of the project to improve;

Lean construction quality control is based on the end of the plan theory and the combination of BIM technology, Kanban based on the BIM simulation and synergistic to realize the quality control at each level, and to achieve the quality of the project. The Kanban board is based on BIM's simulation and synergy to realize the visualization of the quality control process at each level, and optimize the content of the quality plan and implementation at any time by using the BIM database information, the resource situation and the schedule requirements to achieve the purpose of continuous improvement of the quality, and the visualization of the control process also saves the cost of the quality control and the unnecessary wastage.

Through the establishment of a comprehensive quality assurance system combined with BIM, the construction quality is ensured by parallel production operations, the work tasks are processed, standardized and flowed, and the all-round, all-process, all-participant comprehensive quality management is implemented to achieve the goal of advanced project quality control and great reduction of quality defects.

5, the application of value

Lean construction is an advanced construction and management concept, the core is to reduce the value of the construction and production activities and links, the pursuit of "zero waste, zero inventory, zero waste, zero defects, zero failures, zero stagnation, zero disaster". The core of the company is to reduce the production activities and links without value, and pursue the goal of "zero waste, zero inventory, zero defect, zero failure, zero stagnation, zero disaster" to improve management efficiency and create more value for the project with innovation.

The realization of the lean construction concept requires timely and accurate processing of various project information, and the tasks of pull timing, total quality management, teamwork, parallel engineering, etc. are continuously improved with precision.

From the perspective of the entire construction industry, the synergistic use of lean construction and BIM

reduces waste, lowers costs, changes the construction industry's traditional sloppy management mode, and enables the construction management mode to move toward refinement, realizing the healthy and sustainable development of the construction industry.

BIM is the digital expression of the entity and functional characteristics of the project, while integrating various information of the project, BIM model based on the "visualization" of the three-dimensional digital construction of the project program for the project design, construction and operation and maintenance of the whole participant as well as the technology of the links to provide a collaborative platform to promote the lean construction concept to achieve the goals and application of the ground. The application of BIM model features can assist the entire production elements of a project to provide the right product supply at the right time in accordance with the amount required by the project and according to the work standards, so that the project is optimized globally, with minimum waste and maximum value.
