Site material management is a scientific strategy. Materials Management is the process of planning, execution and control of field and office activities in construction.
The materials management goal is to ensure that building materials in their point of view if you want to. Materials management system endeavors to ensure that the correct quality and level of material is appropriate, purchase, delivery and on-site handling in a timely manner and at an acceptable cost. Materials management system attempts to ensure that the correct quality and quantity of material is appropriate select, purchase, delivery and on-site handling in a timely manner and at a reasonable cost. So Materials management is an important factor of job management. The materials shows a major cost in the structure, thus lowering procurement costs to increase the opportunity to reduce the expense of the entire job.
Construction assignments, building materials fees accounted for 60 to 70% of the project cost. A moderately organized planning, supply and use of creating materials, development materials from the creation companies enter into a construction in line with the variety, volume, quality, duration, lowering the copy of part ofprevent the backlog of waste, shorten the engineering period, speed up the construction swiftness, reduce the price tag on the task is important.
2. 1 Range of Materials Management
It was discussing the many functions of materials management of the materials management coordination of various departments of manufacturing enterprises. After the material procurement and brought by the organization, its value is constantly on the increase other costs of materials required for the sorting, transporting materials in inventory, maintenance and management costs must be assigned to the price tag on materials before entering into a product or converted to other form. To conserve the cost of all the materials management company has taken a clear method to determine the amount of material is ordered, the quantity is stored as inventory and in-process inventory. To be able to reduce the cost of materials and other costs, there has to be effective and efficient management of materials technology, it must be dynamically modified with changes in demand and development.
2. 2 Goals and Functions of Materials Management

2. 3 The different parts of material management
2. 3. 1 Material resource and management
Through general market trends, to check out the skilled materials
The range of inspections, investigations should first production and management sellers. One is the audit inspection material production and operation of the primary body of all types of production and operation procedure is a full range; The second is on-the-spot investigation enterprise production scale, management theory, sales and after-sales service, etc; The third is mainly studies the business of quality control system, whether it has countrywide and industry product quality authentication, material quality in the similar products is to participate in the general, intermediate or high-grade, etc.
Another study appointments range is building industry. Throughout the understanding of the building industry, information obtained a more appropriate, more careful, more comprehensive. Generally speaking, excellent quality materials will get architectural recognition, inferior quality of materials will be people spit on. By understanding building industry, can become more accurately excel at the material maker venture reputation, product quality, price condition, the post-sale service, etc.
The material the procedure test
Acceptance warehousing must ask the company of creating materials "security record to prove". The materials inspection units must have the appropriate screening facilities and capacities.
Materials management in the structure process
The central task is to check the utilization of the materials management process to ensure the quality of the materials entering the building safekeeping of materials methodology, strict, acceptable use of a variety of materials, reduce ingestion, to guarantee the realization of the management aims.
2. 3. 2The price of materials management
1. Control of the marketplace, reduce the price of materials
Control of the market, the market price is the comprehensive assortment of materials. Materials price information-gathering process, price information collection is in the building materials market, the materials origin, the course of the inspection. The acquisition price information must be appropriate to the actual situation of the market to reflect the general level of prices of materials. Research and assortment of price information for executive materials, covers a wide range, heavy workload, is a intricate information system.
2. Use the market, reasonable plans for transportation
Freight expenditures are important factors that constitute material procurement costs, save on delivery costs, reduce material procurement costs. Therefore, to consider the following aspects should consider the problems of the transfer distance transportation cost benefits: materials when ordering. In the case of material quality, performance can meet up with the material procurement program, and almost equal to the price of materials, it will go directly to the nearest location away from the engineering site procurement; materials as a travel in place, to lessen supplementary unlucky and handling costs.
Take reasonable function of procurement
Doing so source, storage, integration, reducing both people arguing backwards and forwards; owner can reduce material prices, decrease the project cost; course reasonable supply mode relating to specific circumstances.
2. 3. 3 Materials storage concern management
Specifically the Treasury, proper storage. Identified clearly, categorised storage
In addition to the release of the material, whether by the Ministry branch or the issuance of project department warehouse products, should implement the concept of "first-in, first-out" job materials consumed should be read in conjunction with the segment and sub-project accounting, tight implementation of quota / set picking system must be opened up by the job construction workers before construction sign limits pick and choose lists limit go with lists must fill up part requirements essential items. Valuables and a larger amount of items, multiple payment based on usage, with picking small solution points. Easily destroyed goods, the material need for more descriptive experience exchange members issued by the recipients of the two sides to signal off on the qualification.
Material need made from site
Material purchased in the store
Indents is generated
Check availability in the store
Check for the balance items
Vendor selection from the approved set of suppliers from the client
Material inspection from the received stock
Rejection of the unacceptable stock
Issue of material to the worried department
