The development of prefabricated technology is in full swing. We have compiled a few things that cannot be ignored about "prefabricated" in 2017, which we believe will be helpful for engineering construction. Let's take a look together.

government sector



In the opinion of the General Office of the State Council on promoting the sustainable and healthy development of the construction industry, it is mentioned that, (III) Accelerate the implementation of general contracting for engineering projects. In principle, prefabricated buildings should adopt the engineering general contracting model. Government investment projects should improve the construction management model and take the lead in promoting general contracting of projects. Accelerate the improvement of systems and regulations related to bidding, construction permits, and completion acceptance for engineering general contracting. According to the principle of general contracting taking overall responsibility, implement the responsibilities of the engineering general contracting unit in terms of engineering quality and safety, progress control, cost management, etc. Except for projects that are included in the scope of general contracting and must be tendered according to law in the form of provisional estimate, the general contracting unit may directly contract other professional businesses covered in the general contracting contract

Industry supervisor

At a press conference promoting the sustainable and healthy development of the construction industry, Yi Jun mentioned, "By promoting intelligent and prefabricated buildings, promoting innovation in construction methods, achieving standardized design, factory production, prefabricated construction, integrated decoration, information management, and intelligent application."

The Ministry of Housing and Urban Rural Development held a national symposium on prefabricated building work, which mainly discussed the development technology of prefabricated buildings, exchanged information on the development of prefabricated buildings in various regions, and deployed the promotion of prefabricated building work.

The Ministry of Housing and Urban Rural Development has issued notices on the "Thirteenth Five Year Plan for Prefabricated Buildings", "Management Measures for Prefabricated Building Demonstration Cities", and "Management Measures for Prefabricated Building Industry Bases".

The Ministry of Housing and Urban Rural Development has organized relevant units to prepare the Technical Review Points for Construction Drawing Design Documents of Prefabricated Concrete Structures in accordance with technical standards such as the Technical Regulations for Prefabricated Concrete Structures.

The Ministry of Housing and Urban Rural Development mentioned in the letter soliciting opinions on the "Special Qualification Standards for Construction General Contracting Enterprises" (draft for soliciting opinions) that the construction projects in the enterprise's engineering performance have undertaken construction general contracting or main engineering contracting for three of the following four categories in the past five years, and the engineering quality is qualified.

(1) Buildings with a height of over 120 meters;

(2) Two construction projects for reinforced concrete structures with a single span of more than 30 meters (or steel structures with a single span of more than 36 meters);

(3) Construction projects with a single contract amount of over 500 million yuan undertaken through general contracting;

(4) Prefabricated prefabricated building projects with a height of over 60 meters.

The Ministry of Housing and Urban Rural Development has organized the preparation and issuance of the "Consumption Quota for Prefabricated Construction Projects", which will be implemented from March 1, 2017. The "Consumption Quota for Prefabricated Building Engineering" is used in conjunction with the "Consumption Quota for Building Construction and Decoration Engineering" (TY01-31-2015), and the relevant installation sub items of prefabricated building components (quota numbers 5-356-5-373) in the original "Consumption Quota for Building Construction and Decoration Engineering" (TY01-31-2015) are simultaneously abolished.
