Materials management is an activity for planning, executing and controlling field and office activities in construction. the purpose of materials management is to insure that construction materials can be found at their point of use when needed. the materials management system attempts to insure that the right quality and level of materials are appropriately selected purchased, delivered and handled on site regularly and at a reasonable cost. materials management is the machine for planning and controlling every one of the efforts essential to ensure that the right quality and level of materials are properly specified in a timely manner, are obtained at an acceptable cost and most important element in project management. materials represent a significant expense in construction, so minimizing procurement costs boosts opportunities for reducing the overrall project costs. poor management can cause increased costs during construction.
2. Need for materials management
Materials management is the important guarantee of creating construction quality of products or materials management is important to lessen the price of the project hand.
3. Materials management benefits
Effective plans to generate and enhance the system of material management master plan by completing the gaps and production of environmentally responsible and effective results. institution campus, effective management of the office or home can expect from materials program provides an array of benefits. first, the long-term cost benefits, as consolidation, reconfiguring, and better management of the campus core infrastructure to reduce annual operating costs. institution campuses, office or home and get the best and best use of the campus property.
materials management is a highly effective means of a more comprehensive approach to managing material use and emissions, solid waste, hazardous waste, recycling. request today become more environmentally friendly.
Finally, effective management can enhance the aesthetics of materials. remove unsafe and unsightly conditions, will generate the best sight, creating a more pedestrian - friendly environment, enhancing the living and working in the visual and physical sense.
Better accountability on part of materials and also other departments as noone can shift blame to others.

A materials management system is normally controlled through an informationsystem, thus, can assist in taking decisions related to material in theorganization.
One indirect advantage of material management is the fact that good quality materialdevelops the ethical and moral standard within an organization. However, pleasenote there is no study upon this issue.
·Are very important to the management of the building materials materials management is to reduce construction costs and one of the main ways to control construction quality, material management methods correctly can provide high - yield and high efficiency for engineering materials give a guarantee of nature can reduce the construction cost of project on the profitability of construction enterprises play a key role.
·Building material of construction is the basic condition is also an important part in the construction engineering management. management of creating materials from ensure the grade of construction works on the basis reduce the price of construction.
A budget, materials management
Storage of materials management
Project closeout phase materials management
When construction reached the finish of the construction stage most engineering materials have been using also not neglect the management of the material. we ought to carefully check the remainder of the construction site of adjust based on the progress of the construction supplement the shortage of construction material, corresponding processing avoid the extra material on completion of the project a significant amount of material remaining cases decrease the handling for the next time. for engineering construction management of waste, the waste produced in can be used to gather again using.
4. Disadvantages of materials management
·Continuous observation is required.
·. Extra-manpower required.
·Huge investment once and for all infrastructure facilities.
·Building material category of construction site confused, and represent a substantial proportion of the expenses in the price of the project, general civil construction accounted for approximately 70 % of the total cost, materials management and accounting is good or bad, on the control of engineering cost of production, monetary efficiency is good or bad, processing speed of cash flow, cash flow is of great significance such as profit and loss. Beneath the premise of how to guarantee the quality of engineering, acquisition, use and management of various materials in an acceptable manner, to lessen the liquidity of an occupation, to reduce construction costs, it is vital.
·Project partially decentralized purchasing patterns cause confusion for procurement of materials
The material of construction enterprises Department of procurement authority to the project, although has the good thing about flexibility, but there are some problems. First, project the department of in professionals less than situation, non permanent deployed non - professionals engaged in material purchase management work, not only efficiency low, and difficult to guarantee material quality, more may for engineering in the use fake material, caused major engineering quality or personal accident ; second, the project the department of respectively the establishment of warehouse, their own, material difficult to add spice to, will lead to management costs increase, funds working capital slow ; again, dispersed purchase - shaped not scale bulk, difficult to implementation of purchase price poor, enterprise the overall monetary benefits decline in. Therefore, the use of decentralized procurement model, greatly influenced the economical benefits of material procurement management, even to the whole management of construction enterprises bring a degree of confusion, leading to material management of enterprises in a state of disorder.
·To manually manage the difficult to adapt to certain requirements of modern enterprise development
At present the majority of the material management of construction enterprises still stuck in the manual management of the State. Materials from the library to the library to undergo lots of links, manual management is not only inefficient and prone to human error. Much like management to inventory information exchange between the Treasury, will easily lead to inventory backlog affect cash flow. Furthermore, a wide variety of building materials, manually will cause data summary and analysis of difficulties, and real-time, dynamic control for material difficult to achieve.
·Materials management personnel's quality should be improved
At present, the grade of building materials in construction enterprise management personnel is generally not so high, most are not professionals, and some have even not received professional training, it is difficult to meet the needs of building construction enterprises. In fact, materials management on personnel requirements are extremely high, in addition to good ideological and political quality, compliance with national regulations, and to know about building materials market, flexible use of various procurement methods, have an increased contract negotiation skills and an enthusiastic market sense of smell. Question for now is a lot of people who have experience in materials management, often the theory of literacy and professional level is not high, and having less management capacity of the machine, and students with a higher degree of theoretical knowledge and lack of working experience because of insufficient experience. Good thinking, consciousness is high, the style is, both with theoretical knowledge and practical experience of compound talents of a significant.
·Material management system is not sound
Some of the construction of no importance to material management system of Construction Enterprise, lead to unsound system, materials management is very haphazard. There is absolutely no strict verification, head of site construction materials Request Form, granted approximately you want to. Some material led the task is not complete, leading to physical and Book of engineering materials, and materials management information untrue. Many can recycle and reuse of waste management, leading to material waste. Materials bring that around, bad bad corrosion, low effective utilization, even if the materials have been stolen too little, virtually increases the total cost of the project.
5. Material management system in construction site
aterial acceptance and storage systems Site Materials required by the customer purchases back again to back, acceptance of the material should be completed.
·Material acceptance of custodians and materials, and acceptance of material should be received by the bill of materials for acceptance into the material name, the number of a column, And carried out checks on the grade of materials for the library, acceptance than to the principle of applications to come back the excess quantity, But if necessary, approved by the leadership approved the approval can be appended after the procurement procedures of storage.
·Acceptance of materials will be conducted in approaching the location of materials, and the opening of the storage invoices, On storage of materials should fill in the name of the storage material specification make of storage time information by sponsor. And should indicate the purchase order number in storage, to lead the review, therefore of the amount of quality, specification discrepancies should be used in non permanent storage of forms.
·All material storage, must be strictly acceptance, to ensure its quality on the basis of the Measured quantity, According to the several material properties of objects, take points, measured, weighed, the number of parties like the approach to acceptance, the prohibition around.
·For bulk materials, ask for high quality materials, special materials, such as three certificates.
·Because the amount of material large packaging or therefore relations, was unable to be acceptance of the material acceptance. Can number, weight or level of packaging, packaging cases for the preliminary acceptance, After serious tidy up after no more formal acceptance and, if possible, after uncontrollable in the acceptance.
·After the material Library, when deemed necessary by the competent leadership or departments in any way levels, to reinspect to the storage of materials, If it's found that does not match the storage conditions, will pursue relevant personnel responsibilities, leading to the loss, by personnel compensation.
·Is unable of material, such as working capital for the library shelf material, Entry acceptance of the material must be used by warehouse management and construction team designated officer of the next joint participation in and sign the delivery note.
B. Materials used and the utilization of any materials out of the library system of the material must be led with formalities, Material administrators should not be issued without picking process materials except for special circumstances to receive a small amount of material, but must be a replacement after the procedure.
6. Enhance the quality of materials management at the scene
·First, choose a high-quality team of subcontracting is the first rung on the ladder to reduce costs. comparison of subcontracting team on the parties, on the recommendation track to " pick up " better quality than quality than price. work force is site specific production operator, level of service quality will directly influence the grade of construction, in a way concerns a project's success or failure.
·Therefore, employers should first select in select services team who tend to be familiar with, pay attention to reputation, high comprehensive quality of labor force, not only the high or low prices or by virtue of the relationship as the basis for selection, to the first contact, and lack of know services team select use, to from are side two regard to its personnel constitute, and economic of, and social credibility, and business quality, and do engineering such as regard serious investigation, to the by must be relationship introduced services team also not relax investigation, by investigation to services team situation do known, as select services team predicated on the, to the by investigation heart still not the end of which is you want use services team, can be use trial way investigation again do decision.
·Second, the material predicated on the progress of the project plan, timely adjustments to get plan, to balance their material length, turnaround times, using cycles, avoid redundant, blind purchase backlog, modification and just take up space, reduce losses.
·Third, the acceptance of the good material, and rigorous testing of materials to enter the construction site, as well as the original certificate of quality documents and other relevant. to achieve the " medical check, maintain a strict " to remove poor quality material to enter the construction site.
·To no more use or reporting - as - no material with time for the time being, inventory and maintenance. while building material loss account. rental of material cleanup exit regularly, thereby ensuring that minimize the rental fee. material inventory. inventory monthly for usage of and use of materials, to calculate the dosage, interference of the month, and ledger account balances, account should match.
·To strengthen the management of project materials to get rid of low quality material to enter the construction site, must be nurtured to strengthen the management of project materials to remove poor quality material to enter the construction site, must be nurtured high quality materials management team. only in this manner to be able to constantly enhance the quality of materials management personnel to meet up with the needs of the enterprise's construction production.
7. The site materials management
Materials Management in construction site, as its name suggests is through the scientific method, for taking appropriate measures for effective management of creating construction materials at the scene. This is achieved by a management system, rely on scientific control the use of construction materials, supervision of construction quality of recycleables, ensure the grade of construction, reduce the price tag on the project. In order to achieve this for administrative purposes, construction project management should be developed for the materials of construction site management system of rewards and punishments.
Promote the Rational use of shoddy materials, careful reduce material waste, eliminate materials, material loss and loss prevention, reward an acceptable amount of material savings, punishing material waste, reduce project cost, and project management for the Enterprise to produce the most profit. Materials Management in construction site, not merely to lessen construction costs, profit margins create no more than one purpose. In addition, it bears monitoring application materials quality, quantity, for construction projects based on the look requirements, Construction construction see the basis for creating the conditions and specifications.
8. The site materials management features
·according to the construction characteristics of the production cycle, decided to elaborate materials management in construction site wide range of complex and large, liquid, surface keeping more.
·There is a diversity of types of work and procedures for building construction, part of sudden changes, Determines the material at construction site to establish a strict management measures and measures for the Administration to guarantee the smooth progress of the construction.

9. The new site layout
·Thiscase where i believe there are many unreasonable, therefore i made a correction in the following.
10. Aftereffect of materials management
Improvement of enterprise's economic benefit depends upon many factors, one of quite condition is to strengthen the management of engineering materials. Only good material management, is likely to be low priced, high quality, high efficiency, This is in the construction of the importance and urgency of strengthening the management of material is situated. Main problems existing in the management of material a time, in building construction, some projects are high costs, low quality, Low cost-effectiveness, removing multiple reasons, poor materials aren't strict management, is one of quite reasons. Problems in Engineering Materials Procurement. Because the system is not strict, individual procurement officers purchase homes fetch high prices at low prices, although there's a low price to choose the material, but poor material, do not meet the design requirements of the typical. Because of this, poor workmanship, not only caused a lot of waste and damage corporate reputations. Problems in the materials in the library. Some unhealthy or feeding system of construction enterprises and some new traffic controllers low quality, no strict enforcement of the feeding management system, For your material is neither weighed, several, or check the specifications, quality, which bring about high cost, low quality. Problems in the storage and use of materials. Construction materials used are usually bulk material is more, you will need to keep open. Because the system is not strict or keep personnel do not have a solid sense of responsibility, little material deterioration or the material. So in the case should have the above mentioned there is a problem.
Materials management in construction site, so long as the material is required for the project, since the end of to enter the construction site to construction materials to clean the entire process of management, are in scope of material management in construction site. In a nutshell, materials management in construction site, not merely to reduce construction costs, income create a maximum of one purpose. it also bears monitoring application quality and quantity of materials, construction specifications for construction projects based on the look requirements, start to see the basis for creating the conditions and construction.
Strengthening the management of construction engineering materials, it should be good training for managers : strengthening the political and professional quality training of management personnel. in general management ideas, related sector personnel clear own in material cost forecast, and plan the preparation of, and purchase plan the implementation of, and material keep, and material use, and material tidy up process in the essential work program, and method and responsibility ; in business quality regard, to material management employees specific business operation skills training, improve material management workers business procedure ability, and regular rather than regular work effect evaluation, material management staff in competition in the play the major potential
