The project is based on BIM technology, and the cost capital budget The combination of project construction progress effectively shortens the construction period of the project and saves the construction cost of the project.

At the same time, with the continuous in-depth research and development of Internet plus, Internet of Things technology and artificial intelligence technology, the application function of BIM technology is not limited to the two-dimensional building model of parameters.

By adopting the precast construction policy mode of steel structure, It is more in line with people’s demand for new building construction mode at this stage.

It is easy to ignore the delay of the construction period caused by the construction site, construction machinery and construction procedures, In addition, the construction period is usually speeded up by increasing labor or extending operation time after problems are found in the process of on-site construction, which is easy to lead to construction delay and additional cost expenditure.

Therefore, the selected construction scheme is more feasible, economical and applicable, which avoids the waste of building resources and the expenditure of construction period compensation and rework cost caused by unreasonable construction scheme.

At the same time, in the deepening design stage of precast buildings, the BIM technology was used to correlate the production, transportation, hoisting and other processes of components, so as to maximize the construction management efficiency of precast buildings.

At present, BIM technology has been widely used in modern construction engineering practice.

The precast building with steel structure is adopted, and through precise prefabrication and on-site installation of industrial steel structure components, the building construction is more safe, efficient, green and reliable.

Based on the powerful data processing and analysis functions of BIM technology information platform, It can not only accurately calculate the bill of quantities, bill of materials and other details of the project, but also summarize and analyze the relevant data of the project information according to the component type, time and space dimensions, realize the sharing and collaborative work of information data in all participating departments, and provide data support for project managers in capital cost planning, construction material planning and other aspects of decision-making, Further reduce the construction cost of buildings.

① Before the construction of modern cast works, the project cost management has used BIM technology to simulate the construction sequence and hoisting scheme of concrete formwork support arrangement, component hoisting works.

Before construction, relevant factors that may affect the site construction are found in a timely manner, and then relevant measures are taken to solve the problem, and the site construction scheme is improved to improve the rationality and enforceability of the construction schedule, so as to avoid unnecessary rework and construction period errors, Further improve the lean management level of on-site construction progress…

Adding time and schedule management mode can also build a four-dimensional model, and adding cost control can build a five-dimensional model.

② Management of construction design scheme In the construction design of precast buildings in the parking lot, through the use of BIM technology to manage the building construction, the building model, structural model, on-site construction and other visual models have been established, and the collision detection has been carried out for the on-site component installation construction of the same profession and different professions.

The shortcomings of traditional construction projects, such as high safety risk pressure at the construction site, serious pollution such as dust and noise, and long construction period, have some contradictions with the expected effect of people on the preparation of construction products at this stage.

③ In the traditional construction project management, the construction schedule mainly depends on the manual preparation of the construction schedule by referring to the relevant quantities and the construction efficiency of the unit personnel.

The information platform established by BIM technology simulates and optimizes the traditional two-dimensional construction drawings, and the derived drawings include the pipeline layout drawing, pre processed casing drawing and corresponding bill of quantities after construction collision detection and optimization, which further improves the construction management efficiency and effectively reduces the construction cost.

Later, through the on-site construction collision detection report, the B1M technology information platform was used to process and analyze the data, optimize and improve the on-site construction scheme, and provide guarantee for the orderly construction of precast buildings.

For example, In the process of component production and hoisting, BIM technology is used to build models, and then BIM technology is used to build models of reinforcement engineering and hole reservation engineering, collect information data of each component, and use the visualization features of BIM technology information platform to complete intelligent management, so as to prevent the collision between precast components and cast-in-situ connection points, minimize the construction cost and shorten the construction period, Ensure that the interests of relevant construction enterprises are maximized.

However, the manual preparation of the construction schedule is inefficient and the reference quantity is not comprehensive.

Modern precast buildings, with their unique construction mode, avoid the disadvantages of traditional buildings, such as long construction period.

In this regard, BIM technology is used to simulate and rehearse the construction process of component hoisting, and the whole process of component installation is demonstrated intuitively and completely.

With the rapid development of China’s social and economic construction, the construction technology and methods and the level of construction technology in the construction engineering industry are also constantly improving.

At the same time, people’s demand for construction products is increasing rapidly.
