Project management of road and bridge construction business problems and solutions

Our road and bridge industry in the late 90s of the last century really implement project management, through 10 years of development, we have made great progress, but the overall management level is still not high. In recent years, roads and bridges engineering quality accidents of more delays in the construction period is more prevalent, construction profits generally not high, it is not standardized and project management, operations can not say no formal relations, including construction site management confusion, the construction process waste larger, project procurement management and other issues behind particular.

One problem: the construction site management confusion

Road and bridge construction site workers and other management personnel directly engaged in construction activities, create value and social value of place, productivity carrier. Construction progress of speed, quality of the pros and cons, the level and efficiency of the quality costs are closely linked with the construction site management.

Many of road and bridge construction enterprise project management is very confusing, the prevalence of unplanned construction, operating without standards, rules and regulations are not perfect, job responsibilities are not implemented and so on. At the same time, management of road and bridge construction business machinery and equipment is relatively backward, high failure rate; materials, machinery, equipment at the construction site of dumping of both led to waste, but also easily lead to quality and safety incidents. Therefore, strengthening the construction site management, at the construction site construction workers to improve conditions, strengthen the construction site of the standardized operation of enterprises is particularly important for road and bridge construction.

The second problem: the construction process, there are more waste

Construction process refers to the processes of construction, ie multiple sets of continuous activity. According to the definition of the value stream, value stream is an enterprise run from the beginning to the end of the plurality of sets of continuous activity, these activities work together to create value for customers. Customers may be external customers, it may be worth the flow inside the end user. If the process of an activity does not create value for the external or internal customers, it is considered waste.

In road and bridge construction, the construction process there are more such waste: First, because the process design is unreasonable, resulting in the presence of a large amount of waste material in the actual construction process, waste material is particularly serious, business and therefore increased the number of additional costs; Secondly, the irrational process makes use of mechanical equipment efficiency is not high; in addition, the process also results in irrational waste of human resources.

Three of the problem: behind Project Procurement Management

Procurement management of road and bridge construction projects generally lag behind, which is an important factor to improve project profitability constraints, specifically in the following three points:

(1) Bulk purchase less, no economies of scale, greater procurement costs;

(2) The construction project is not formed strategic alliances with suppliers, more short-term behavior is not conducive to sustained reductions in commodity costs;

(3) construction project with suppliers in the process of cooperation, mainly in the price of the center, so easily lead to vicious competition suppliers, engineering products to legacy risks.

Lean thinking that in order to reduce production costs must first rule out all kinds of waste, lean core production is to eliminate waste. Lean about the theory and method of construction, that 5S, JIT, flow concept, pull production control system, standardization of production, production methods such as equalization can effectively solve these problems.

Method One: Implementation of 5S management method

5S method is an order (Seiri), rectification (Seition), cleaning (Seeso), clean (Seiketsu), literacy (Shitsuke). "Finishing" refers to articles divided into useful and useless, and will get rid of unwanted items. "Rectification" means reasonable arrangement where and items placed in, and make the necessary mark. "Cleaning" means the elimination of waste, dirt and stains in the workplace. "Clean" means the continued implementation of the order, straighten, clean-up work, and make it standardized and institutionalized, to keep the workplace clean, comfortable and reasonable. "Literacy" means require staff to establish self-discipline and develop the habit in the 5S work that requires daily work 5S becomes conscious behavior.

Method two: the implementation of JIT production system

JlT: Core (Just in time for real production systems) to pursue the following two aspects: first, the pursuit of zero inventory or make inventory to achieve minimization; second, the pursuit of rapid response, which respond quickly to market changes. Implement JlT, production time as the first target, which requires suppliers to supply can not advance, can not be late, or in the production process, a process of production of the product happens to be the next process needs. Of this it is that inventory, delivery on time, thereby reducing the number of warehouses, reduce storage costs, reduce capital used to reduce the company's management and production costs.

Method three: a "flow"

The so-called "one-piece flow" production refers to the work sites, personnel, equipment and reasonable configuration, so that products in the production of, at most, one in each process or finished products to produce before the start to finish, there is no place at the venue of the product operations. "A flow" production also requires strict procedures in accordance with certain beat production. If the procedures are inconsistent tact, there will be product backlog and stagnant, unable to form "a stream."

Four: pull production control system

This method means that from the perspective of the owners, in the construction of the allowable range is determined by the needs of the information needs of owners of the sub-projects in each sub-project decided to demand of each process, every procedure, every departments are in accordance with the then need to move a process, a sub-project put forward demands to issue a directive on procedures, sub-projects according to these instructions completely before term construction.

Five: the establishment of standardized production

Standardization is the basis for continuous improvement and employee empowerment construction process is an important way to improve productivity. The standardization work to avoid defective products, operational errors, and other unexpected situations recur, reduce management costs, improve process quality.

Further standardization should continue to be refined in order to adapt to changing environments.

Six: Production equalization

Equalization is fully synchronized construction schedule requirements and market demand, namely from ready to purchase building materials, allocation of funds, equipment, and any link provided, have been allotted the interface should work in harmony with the market demand. Both are not allowed to prepare in advance, but does not allow delay. Construction equalization mainly rational use of corporate funds, the rational allocation of personnel to ensure the supply of construction materials at reasonable.
