With the development of construction enterprises from labor-intensive to technology intensive management, transformation, project management mode is changed, and the interests of project manager's earnings are closely linked, more autonomy of the project manager, project manager in the choice of labor force when to focus on the price level, resulting in difficult and labor service company individual labor contractor labor competition, affiliated, layers of subcontracting phenomenon repeated.

In the choice of labor force, it is difficult to regulate the bidding process, some owners or local officials in various ways to intervene labor subcontracting bidding activities, resulting in the construction of the system, measures and new technology, new standards of ineffective implementation, the level of construction quality is difficult to guarantee the production safety accidents have occurred, some labor subcontracting engineering contractor after the project will be two times, three times the subcontract.
Secondly, the construction labor subcontracting enterprises in short supply situation is grim, labor subcontracting enterprises more low profit, can not afford the insurance, staff skills and training as well as the tax, and keep technical ability and compound talents, there are many service enterprises law concept, the lack of a sense of responsibility, once the problem is to the general contractor, the owner and the government responsibility.
He fled, and after the re registration, enter the construction labor market make only superficial changes, safety and quality consciousness, and because of labor flow is large, most general contracting and professional contracting enterprise not willing to take on labor skills training, the majority of enterprises have not the strength of labor skills training for service personnel, service personnel quality and safety awareness occupation skill level needs to be improved.
The majority of migrant workers are in no other suitable jobs into a situation of the construction industry, pick up the lost sickle cleaver, without the necessary professional knowledge and occupation skill training, resulting in the lack of high level technical workers, in addition, there are also some shehei phenomenon of labor service enterprises, to discuss the wages of migrant workers as an excuse, organization of social nature people, even the evil forces, and usury company colluded to illegal and violent forced contracting enterprises, owners, government departments.
On the other hand, the general construction contractor enterprise lack of binding on the labor service personnel, service personnel only obey his command and direct employer does not obey the general construction contractor enterprise personnel management, stable industrial workers can not be formed, enterprises are difficult to grow, at present, truly meet the requirements of national standards for the qualification of construction labor subcontracting enterprises less quantity, there supply situation.
In this way, the labor force under the guise of bidding to become as a mere formality, it is difficult to guarantee the labor force business skills, what is more, the subcontractor on labor relations with the owners, government officials, do not obey the general contractor's management in the construction process, coordination is difficult, the general contractor is very passive, resulting in management cost and span execution is too large, on the one hand, the development of decline, labor subcontracting enterprises control the size of the construction labor subcontracting enterprises.
On the other hand, labor enterprises access threshold is low, the majority of migrant workers with low level of education, lack of occupation skill training, usually the construction contracting enterprises have a complete system of project management system and management system, but after implementation of labor subcontracting, the management system and the corresponding measures to carry out labor only team, but are not very good in the implementation of labor service personnel.
Especially the quality management system, safety management system, technical operation, enterprise management system is difficult to penetrate into the depth of each operating post, technical disclosure form, construction log deletion, security management, serious waste of materials. The main reasons are: on the one hand labor workers lack of systematic training, comprehensive ability and the quality is low, difficult to accept and understand the substantive requirements of the enterprise management system.
Only their own understanding and experience to do the operation, team organization slack, the overall quality is not high, can not meet the needs of the market economy and the development of enterprises, some of the "labor contractor" in order to obtain profits, take various means deduction of wages, or in order to get the project progress, incite migrant workers Taoxin collective organization, the construction enterprise itself cash flow difficulties exist problems in the payment of wages is not in place, not timely communication conditions, which lead to mass incidents.
This to a certain extent has become the rural surplus labor to the construction industry output of the "bottleneck" problem, which also hindered the construction service enterprises to improve the overall quality of the package, the engineering quality is affected, production safety accidents, the majority of labor service enterprises, registered capital of small scale, resist the risk faced by the lack of capacity, and because the artificial fixed fee standards and market the real wage gap, increasing labor costs, gas bearing received labor subcontracting tasks, makeshift migrant workers, while the majority of migrant workers lack of organization, low education level, without occupation training into the construction industry, occupation skills and overall quality is not high, it is difficult to to ensure the construction quality and safety of construction.
