Before the formulation of the scheme, it is necessary to understand the attribute information of the components, so as to load and place the precast components, and scientifically design the spacing between the precast components.

The government should adjust the VAT rate in light of market conditions.

Specifically, modern science and technology and intelligent mechanical equipment should be fully used to achieve mass production, and at the same time, the waste of resources caused by mechanical downtime, vacancies, etc.

The production process of precast components is complex, and the layout of production equipment and work area is unreasonable, which will inevitably affect the production efficiency and cause waste of resources.

(1) Improve the standardization level of precast building design In the design stage, the standardization level of design should be improved, and the prefabrication rate of precast components with consistent size and specification should be improved to achieve batch production and transportation.

In addition, the layout of production facilities and work areas should be optimized and a reasonable production mode should be selected.

Secondly, we should pay attention to the technical training of construction personnel and improve the comprehensive quality of on-site management personnel.

Finally, advanced technologies such as BIM, GIS and 3D printing should be flexibly applied to improve construction quality and efficiency.

Relevant departments shall regulate and manage according to market demand.

At the same time, reasonable transportation routes and emergency measures shall be formulated according to traffic conditions and construction progress.

For example, the components installed for the first time shall be placed on the outermost or uppermost side of the vehicle and numbered to facilitate smooth transportation.

(3) Strengthening the transportation management of precast buildings In the transportation stage, the transportation scheme should be optimized first.

In addition, UAVs can also be used to conduct aerial survey on the construction site, process the aerial survey data, establish a real 3D GIS point cloud model, import it into the BIM 3D construction planning software, simulate and adjust the layout of temporary facilities, and allocate the mobilization and demobilization time of large machinery in combination with the construction schedule to save the construction period and cost.

During the transportation, the transportation plan shall be strictly followed.

Specifically, designers should design components according to the whole process of precast building construction in the principle of facilitating mass production, and try to unify the shape and size of components without affecting the safety quality.

(2) In the production stage, enterprises should first expand the production scale and improve the mechanization and intelligence of production.

The construction process shall be carried out in strict accordance with the schedule, and the hoisting method of precast components shall be standardized, and the hoisting sequence of components shall be reasonably arranged.

For example, during the production process, the management personnel can focus on the demoulding and maintenance of components, and develop a reward and punishment system for production workers to prevent the failure of component strength.

For example, in the early stage of construction, BIM+GIS technology is used to simulate earthwork balance to reduce earthwork quantities, and accurate estimates are made for vehicles, personnel, etc.

Secondly, the government should deepen the standardization reform and improve the standardized management system that is unified, coordinated, efficient and co governed by the government and the market.

should be avoided.

Secondly, enterprises should pay attention to the cultivation of professional level of production personnel, strengthen the training of technical personnel, and do a good job in relevant management.

Vehicles shall be dispatched reasonably, and components shall be placed reasonably according to the order of use on the construction site.

Secondly, transportation process management should be strengthened.

(5) To strengthen the macro-control of the government, relevant government departments need to strengthen the macro-control of precast buildings.

The mathematical model and optimization algorithm are established, and the optimal production equipment layout scheme is solved by computer to reduce the production cost of components.

(4) To improve the construction efficiency and quality of precast buildings, scientific management and reasonable arrangement of construction steps should be the first step in the construction phase.

At the same time, we should strengthen the professional ability training of designers, improve the professional level of designers, formulate reasonable design standards according to the actual development of precast buildings in China, and promote the development of precast buildings in the design phase towards a more efficient direction.

The improvement of the quality of construction site personnel is not only conducive to reducing cost consumption, but also conducive to the long-term development of the construction industry.

First of all, the VAT rate of precast components of precast buildings is far higher than that of traditional building materials.

This article is excerpted from the “Research on Difficulties and Countermeasures of Cost Control of Fabricated Buildings” in Building Economy, Issue S1, 2022.

At present, the universality of existing building component standards cannot meet the needs of precast buildings, and the standards for collaborative work and refined design, such as pipeline coordination interface standards, are lacking.

Before component transportation, a good transportation scheme can effectively reduce the cost.
