Second-tier enterprises:It can undertake the construction of curtain wall projects with a curtain wall area of less than 8,000 square meters for single building projects.

First-class enterprise: can undertake the construction of various types of building curtain wall projects.

Since November 1, 2016, in addition to the lowest level of qualifications, the index assessment of registered constructors, personnel with intermediate titles or above, on-site management personnel with post certificates, and skilled workers will be cancelled. (Notice of the Ministry of Housing and Urban-Rural Development on Simplifying Some Indicators of the Qualification Standards for Construction Enterprises, Jian Shi [2016] No. 226).

Precautions for building curtain walls.

Hidden frame curtain wall and semi-hidden frame curtain wall usually use pressure plate (briquetting) to transmit force, and its spacing is generally not more than 300mm, and there are two kinds of fixed distance and non-fixed distance pressure plate. After the fixed-distance pressing plate is tightened by the connecting bolt, the crimping gap is relatively fixed, and the compression force of the glass panel sub-frame is relatively consistent, which is convenient for absorbing the deformation of structure and temperature, reduces friction noise, and can avoid the image distortion of the glass panel caused by uneven briquetting.

The false exposed frame usually adds a decorative strip at the joint of the hidden frame curtain wall to play the decorative effect of the exposed frame curtain wall. This structure should be designed with insulating glass and structural adhesive using the design method of concealed frame curtain wall, that is, the second sealant should be sealed with silicone structural adhesive. If polysulfide glue is used as a second seal for insulating glass, although it may not necessarily be destroyed under UV irradiation, there are still unsafe factors.

It can undertake the construction of building curtain wall with a single contract amount not exceeding 5 times the registered capital of the enterprise and a single project area of less than 8,000 square meters and a height of less than 80 meters.

Second-level qualification curtain wall enterprise: can undertake the construction of building curtain wall projects with a single contract amount not exceeding 5 times the registered capital of the enterprise and a single project area of 8,000 square meters and below, and a height of 80 meters and below.

Secondary qualification: It can undertake the construction of building curtain wall projects with a single contract amount not exceeding 5 times the registered capital of the enterprise and a single project area of 8,000 square meters and below, and a height of 80 meters and below.

The second-level curtain wall qualification can undertake the curtain wall project of a single building project with a curtain wall area of less than 8,000 square meters (including 80,000 square meters). The first-class curtain wall qualification can undertake the construction of various types of curtain wall projects before building old buildings.

The building curtain wall is an indispensable part of the modern city, one of the important structures of contemporary architecture, and one of the main symbols of the modern city. There are many types of building curtain walls, and the technical strength has also developed rapidly with the development of the construction market. Architectural glass curtain wall construction enterprises need to obtain the corresponding curtain wall secondary qualification certificate.

Application for second-level qualification conditions for building curtain wall:

1. To apply for the second-level qualification of building curtain wall, there must be no less than 4 registered architects majoring in architectural engineering.

2. The project leader has more than 8 years of experience in engineering construction technology management: has an intermediate technical title in construction engineering related majors or has passed the professional qualification examination of registered architect (or registered structural technician) in construction engineering. At the same time, the second-level qualification of building curtain wall has requirements for personnel performance, and it is stipulated that the project leader or registered architect has organized no less than 2 projects of flow and killing.

3. Regulations on building curtain wall qualifications and technical personnel: no less than 10 intermediate or above technical personnel who meet the requirements after assessment or learning and training apply for the second-level qualification of building curtain wall. <>
