space truss structure construction should be the independent branchsteel structure disgn ersonnel, engineering and technical personnel and skilled workers gap is very big, especially the construction division (project manager) and technicians, technicians has become the bottleneck of development, there are a lot of policy issues, operation, need to study.
First, the qualification access system is not perfect. The original qualification standard, the paper put emphasis only on enterprise's registered capital, project manager and engineering and technical personnel, engineering performance, to the enterprise have steel structure manufacture base no provisions, many with civil construction company is very easy to review to the steel structure of the additional work. In fact, most of them do not have a certain scale of steel structure manufacture base, relatedsteel structure engineeringTechnical staff and technicians. The company is responsible to civil primarily tosteel structure engineeringAfter the project subletsteel structure supplier; Some companies in order to reduce the cost, and even will besteel structure engineeringSublet no qualification of steel structure of small, to the project quality, people's life and property to bring the security hidden danger. The society for some people, a few pieces of steel plate welding together form components, then put these components like as building blocks together, can make money. Little imagine, steel structure is a high content of science and technology of system engineering. At the end of the twentieth century, a heavy snow overriding a batch of light steel plant, in the society caused great repercussions. Cause the cause of the accident is the construction of the does not pay attention to science and technology, ignore the existence of laws and regulations, make no card design and unlicensed construction. It is a comfort, at present a lot of civil company have seen steel structure good prospect, has started construction steel structure base, the introduction of steel structure talents.
In addition, the JiXieYe into construction steel structure enterprise often with no project manager and related construction personnel, no project performance and can't get the qualification certificate, also some due to the low level of qualification restrict its development. Sichuan province steel structure association has issued a to these enterprises by temporary qualification policy, the effect how? Wait and see.
Second, largesteel structure supplierNo general contracting qualification. At present,steel structure supplierOnly the steel structure specialized contracting qualification. A lot of steel structure engineering need to give priority to construction general contracting company, a project based part is only in reinforced concrete and the construction company control, this kind of phenomenon often appear, leading to a largesteel structure supplierTo a low level of civil engineering company working phenomenon emerge in endlessly. The author thinks, appear this kind of phenomenon is very reasonable, also can give the construction industry, steel structure industry has brought a lot of negative consequences.
Capital, schedule, quality, time limit for a project general all by project total contractor control make thesteel structure supplierVery passive, steel structure of the advanced nature tend to be backward management and system flooded. Many civil company managers because do not understand steel structure technology, in order to catch the progress of the projects, leading to accidents occur frequently. Steel structure production efficiency is higher, there should be a higher profits, based on a variety of reasons, the steel structure has become a small profit industry, can only rely on amount of growth to develop their own, in the long run, is not conducive to the development of the industry.
The author thinks that, in order to steel structure is given priority to project,steel structure supplierThere should be a corresponding general contracting qualification. The problem we have called on for many years, in our calling and strive to, some local part adopted. The good news is that, in the new qualification standards, said the level of qualificationsteel structure supplierSecondary civil company can contractsteel structure engineering, can the contracting, and we hope that this problem can be solved as soon as possible.
Third, industry classification is not clear. At present,steel structure supplierIn the process of construction project, the construction as a part of the provinces to housing and urban and rural construction supervisor, in safety and quality, qualification evaluation, personnel training, tax management are integrated into the construction sequence. In the provinces and cities, and the competent department in charge ofsteel structure supplierVest in manufacturing enterprise. Ownership is not clear, bull management, bull charging status letsteel structure supplierAt loose ends, burden.
At present, the relevant departments will steel structure into civil system in qualification evaluation, personnel training and steel structure, make out the training out of the construction crew, quality engineer and librarian, safety officer, materials can not adapt to the steel structure of the corresponding work, also can not adapt to the project managersteel structure engineeringManagement, to the steel structure industry talent reserve, growth and development to bring a lot of disease.
Fourth, the corresponding institutions not professional steel structure. Steel structure enterprise existing main technical personnel by the transformation of the former enterprise's technical cadres from outside and the technical staff, most of them familiar with diploma and mechanical engineering. From the current situation look, introduced from outside is most fresh college graduates, from design, construction and mechanical company has certain ability of technical personnel. Whether the original or the technical personnel, construction steel structure in this new industry can quickly adapt to the steel structure of the technical work, after a long run and to learn to work better. Civil engineering professional technology personnel lack of manufacturing process knowledge, don't understand welding, makes the refining chart does not comply with the process requirements; Mechanical professional technology personnel lack of building construction and construction mechanics basic knowledge, although their member clear, but for the whole assembly form construction lack of understanding. We hope that relevant colleges and universities can in the cultivation of the steel structure in professional work.
Fifth, the market is not standard and vicious price competition. Start from the bidding, and in many projectssteel structure supplierMust be tied together with civil company, this limits thesteel structure supplierThe subjective initiative. Bidding for enterprise qualification setting conditions, also along with the owner of the different change. Is housing and rural construction is concerned, steel structure specialized contracting grade a qualification for the highest level. becausesteel structure supplierComponent production manufacturing characteristics, housing and urban and rural areas in the ministry of construction contracting qualification of manufacturing no demands, China steel structure association that is set up manufacturing qualification, contain premium quality. Current situation is: housing and rural construction steel structure specialized contracting qualification and China steel structure association manufacturing qualification with many enterprises unable to agree.
Without a doubt, the steel structure design of concrete structure than more precise and quantities of discrete sex more small, in practice the price change is not big. Based on the market is not standard, the cause of manysteel structure supplierBut with the lowest bid, but still are interacting competition, this will inevitably to the engineering quality cause potential safety problems. The author thinks that, steel structure should be highlighted more the technical content, more should pay attention to high quality cheap, to promote the industry to improve, to ensure the right margins, and promote the application of steel structure in our country.
Six, steel structure should be independent in construction became an independent genre a rookie
The above restriction steel structure industry development fast lane on some problems, investigate its reason is steel structure is between the construction field and manufacturing industry of between a special industries, can not get the attention of the relevant departments and care, not government policy support, can not get the attention of teaching institutions. The author thinks that, steel structure belongs to the construction, become one of the independent branch.
First, the steel structure should be clearly belong to the competent administrative department of construction, which is responsible for housing and urban and rural construction of the government at all levels.
Second, steel structure construction should be as a separate categories for industrial statistics, industry training, industry planning and qualification assessment, including registered construction division and related construction crew, quality engineer and librarian, safety officer, materials and key type of work.
Third, the colleges should set up professional steel structure, cultivate the ability to work independently, applied talents forsteel structure supplierCultivate and transport the corresponding management personnel and technical personnel.
Fourth, the unified tax, take is beneficial to the development of steel construction industry preferential policy.
Fifth,steel structure supplierUndertake to steel structure is given priority to engineering, the issue should be the general contracting qualification.
Sixth, the party awarding the contract should be putsteel structure engineeringA single, the steel structure enterprise for bidding. (China construction news)
