The Scope Of Materials Management Construction Essay
The Scope Of Materials oversight Construction EssaySite textile counsel is a scientific technique. Materials Management is the process of planning, implementation and control of field and office activities in manifestation.The genuines worry goal is to ensure that building substantials in their perspective when you need to.Materials worry system attempts to ensure that the correct case and quantity of somatic is appropriate, purchase, pitch shot and on- lay processing in a punctual manner and at a reasonable cost.Materials solicitude system attempts to ensure that the correct reference and quantity of worldly is appropriate select , purchase, delivery and on-site processing in a timely manner and at a reasonable cost.So Materials management is an Coperni apprise element of despatch management. The corporeal shows a study cost in the construction, thus reducing procurement costs to improve the opportunity to inhibit the cost of the entire contrive.Construction pr ojects, building materials fees accounted for 60 to 70% of the project cost. A reasonably organized planning, supply and use of building materials, construction materials from the production companies enter a construction according to the variety, quantity, shade, duration, reducing the reassign of authority ofprevent the backlog of waste, littleen the construction period, accelerate the construction speed, turn bulge the cost of the project is important.2.1 Scope of Materials ManagementIt was referring to the contrasting functions of materials management of the materials management coordination of various departments of manufacturing enterprises. Once the material procurement and brought by the organization, its value continues to increase contrary costs of materials required for the sorting, carrying materials in inventory, maintenance and management costs must be allocated to the cost of materials before entering into a product or converted to other form. In order to sa ve the cost of all the materials management come with has taken a clear method to determine the summation of material is ordered, the number is interjectd as inventory and in-process inventory. In order to reduce the cost of materials and other costs, there must be effective and efficient management of materials technology, it must be dynamically adjusted with changes in demand and production.Materials management efforts to ensure that the material cost component of the total product cost is the least. To achieve this goal, the control is in the exercise of the following fields.1. Materials Planning.2. Purchasing.3. in taut observeing.4. Inventory Control.5. Receiving, Inspection and Despatching.6. Value Analysis, normalisation and Variety Reduction.7. Materials Handling Traffic.8. Disposal of Scrap and Surplus, Material Preservation.The function of the planning department of the material for future plans to purchase the required materials according to the production plan. In materials planning, budget allocation will also be critical to the materials research progress, for better control.Materials planning, procurement must be done. Purchasing department to purchase materials ground on purchase requisitions from user departments and store departments and production plan for the year. There be four basic procurement activities.a) Selecting suppliers, negotiating, and the issue of the purchase order.b) to hasten the delivery of the goods from the supplier.c) as a liaison between the suppliers and other companies.d) looking for new-made products, materials, and suppliers piece of tail help comp either objectivity.At the time of purchase, the right quantity and quality of the materials must be purchased on time, the lowest scathe and choose effective procurement system, and draw maximal benefits. The procurement is based on the make or buy decision, and also using PERT / CPM effectively.When the project is the purchase of goods, must provide enough storage facilities, so the waste is defamed. Sometimes, to be doubly careful in order to protect the quality during storage.Of these tariffs inventory control department to decide on the type of sorting system, to solve the safety stock influence fixing up the reorder levels and maximum / minimum inventory levels.Responsible for receiving, limited review and shipping department receives material suppliers delivered. In receipt of it, the quantity and quality must be checked. Production of parts and materials specification blueprints and inspection. Non-production items were reviewed. Once it is given according to the specification, the goods will be accepted.Value analysis and standardized to provide maximum range, reducing the cost of materials. It also reduces the range of varieties, but also to help find alternatives to lower-cost materials.Material treatment part responsible for the transport of materials in different departments. There are four basic transport activities.Ch oose the ordinary or chartered carriers and routings to send / shipment requirementsTracing in-bound shipments of material in short supply as requested by production control or purchasing, To assist customers in tracking outbound shipments when asked.audit invoices refund excess charges from operators and finish needed for damaged shipments.Development of technology to reduce menu costs. This may include negotiating with competition the shipper, special study, the position of the dominant plants of the latest products, analysis of the tariff, and negotiations of any number of special arrangements to deal with specific traffic.activities including trading of finished packaging, labeling, and loading the final product.Finally, the processing of waste and surplus must be done to ferment the capital locked in those projects on a regular basis.2.2 Objectives and Functions of Materials ManagementPrimary objectives Which can be classified as(i) Efficient materials planning(ii) Buying or Purchasing(iii) Procuring and receiving(iv) Storing and inventory control(v) Supply and distribution of materials(vi) Quality assuranceSecondary objectives there can be several secondary objectives of materials management. Some of them are given below(i) Efficient production scheduling(ii) To take make or buy decisions(iii) Prepare specifications and standization of materials(iv) To assist in product design and emergence(v) Forecasting demand and quantity of materials requirements(vi) Quality control of materials purchased(vii) Material handling(viii) Use of value analysis and value engineering(ix) Developing skills of workers in materials management(x) Smooth flow of materials in and out of the organizationAchieve all these goals, it is necessary to establish harmony and good coordination between all employees of the materials management department.2.3 Components of material management2.3.1 Material supply and managementThrough market research, and look for the qualified material sThe scope of inspections, investigations should first production and management vendors. One is the audit inspection material production and operation of the main body of all kinds of production and operation procedure is a complete range The second is on-the-spot investigation enterprise production scale, management concept, sales and after-sales service, etc. The third is mainly studies the enterprise of quality control system, whether it has national and industry product quality authentication, material quality in the similar products is to belong to the superior general, intermediate or high-grade, etc.Another study visits range is building industry. Through the understanding of the building industry, information obtained a more accurate, more careful, more comprehensive. Generally speaking, really good quality materials will get architectural recognition, inferior quality of materials will be commonwealth spit on. By understanding building industry, can be more accurately m aster the material manufacturer enterprise reputation, product quality, price condition, the post-sale service, etc.The material the approach testAcceptance warehousing must ask the supplier of building materials security record to prove. The material inspection units must do the appropriate testing facilities and capabilities.Materials management in the construction processThe central task is to check the use of the materials management process to ensure the quality of the material entering the construction safekeeping of materials approach, strict, reasonable use of a variety of materials, reduce consumption, to ensure the realization of the management objectives.2.3.2The price of materials management1. Control of the market, reduce the price of materialsControl of the market, the market price is the extensive collection of materials. Material price information-gathering process, price information collection is in the building materials market, the material origin, the flow of t he investigation. The acquisition price information must be appropriate to the actual situation of the market to reflect the general level of prices of materials. Investigation and collection of price information for engineering materials, covers a wide range, heavy workload, is a complex information system.2.Make full use of the market, reasonable arrangements for transportationFreight expenditures are important factors that constitute material procurement costs, save on shipping costs, reduce material procurement costs. Therefore, to consider the following aspects should consider the problems of the transport distance transportation cost savings material when ordering. In the case of material quality, performance can meet the material procurement program, and almost equal to the price of materials, it should go to the nearest location away from the construction site procurement material as a transport in place, to reduce secondary unlucky and handling costs.Take reasonable mode of procurementDoing so supply, storage, integration, reducing both parties arguing back and forth owner can reduce material prices, reduce the project cost course reasonable supply mode according to specific circumstances.2.3.3 Material storage issue managementSpecifically the Treasury, proper storage. identify clearly, classified storageIn addition to the release of the material, whether by the Ministry branch or the issuance of project department warehouse supplies, should implement the principle of first-in, first-out project materials consumed should be read in conjunction with the segment and sub-project accounting, strict implementation of quota / fixed picking system must be opened by the project construction personnel before construction sign limits pick lists limit pick lists must fill part requirements essential items. Valuables and a volumedr amount of items, multiple payment based on usage, with picking small ticket points. Easily damaged goods, the material need for more detailed experience transfigure members issued by the recipients of the two sides to sign off on the certificate.Material need generated from siteMaterial ordered in the storeIndents is generatedCheck availability in the storeCheck for the balance itemsVendor selection from the approved list of vendors from the clientMaterial inspection from the received stockRejection of the unacceptable stock unblock of material to the concerned departmentFig.1 process of material managementSources National Conference on Recent Trends in Engineering Technology2.4 Benefit of Materials ManagementMaterials management to create a niche in many organizations, which have achieved a comprehensive materials management. These organizations often enjoy the following advantagesThe better accountability part of the material, as well as other departments and no one can blame others.As materials management by a single authority, which can persist to better coordination, because it became the central point o f any substance- associate problems.Materials management departments to ensure a better quality materials provide a request in a timely fashion department. This can lead to a better performance of the organization.A materials management system is usually controlled through a system, therefore, can help decision-making related to the material in the organization.An indirect use of materials management is the development of good quality material, ethical and moral standards in an organization.Comment and evaluate the existing site layout relation to the positioning of the material on the construction site and identify viablesConstruction site materials should be placed according to the requirements of safe and civilized construction program to be trimmed and decorated. Temporary construction water, electricity, roads, completed construction requirements of the standard. For field use reasonable construction plane layout should be structured to minimize occupied by construction land, the layout is compact and reasonable, and at the same time do field capacity neat and clean, the roads are wider, in distinguish with the requirements of fire safety and civilized construction. The construction process to avoid multiple trades in the same venue, the same area for construction and mutual restraint, mutual interference.- Keep work areas free from rubbish and obstructions- Maintain all nucleotide surfaces safe, suitable and free from slip or trip hazards- Ensure floor openings covered or otherwise fenced off-Materials are properly stacked and stored safelyKeep all passageways in good conditions- Unobstructed and clearly defined- Provide adequate lighting- Ensure clear sightline at breaks and cornersStacking of all materials- Ensure the proper heights and correct stacking- Allow sufficient space for moving stock- Store materials in racks/bins- Keep shelves free of rubbish- Keep floors around stacks and racks clear- Check drums and ensure pallets in good repair- Heavie r items stored low and without risk of falling objects- Avoid sharp edges and provide safe means of accessing high shelvesSite manager may face the following problemsConstruction site fugitive building (office) located in work area and near the waste materials faced with many unsafe factors and noise pollution.The area of construction waste, stored waste can not be transported out of the site.such as all solvent waste, oily rags, and flammable liquids,Scrap wood or chips, saw dust waste, and paper bags or cartons. If you perchance cause a fire, then there will be heavy casualties.Most construction workers are exposed to excessive construction noise. One can gettinnitus, a ringing sound in the ears, or a temporary loss of hearing. Exposure tolonger period can cause fatigue duty and nervousness.Concrete batching plant away from the material stores. It should be set in a near vertical transport machinery, as much as possible to reduce the concrete, mortar horizontal transport distan ce. Reduce transportation costs and save time.Store settingConcrete store should choose the higher ground, drainage, close to the batching plant.Inflammable and explosive materials shall not be mixed with other material.Inflammable and explosive materials warehouse layout should comply with the fire and explosion safety distance requirements.Proposed new site layout to improve the existing site layoutmess halltemporary building(office)Workers DormitorytoiletWater SupplySite Entrance trope storey terraceSemi-detached housesPowersupplySite exitTimber storeReinforcementSteel storeScaffoldstoreCement storeConcrete batching plantMaterial storeWaste materialSuggestion/recommendation that will give strong impact on the material management process in the future based on the case studyResponsibilitiesProvide guidance, interpretation and direction to Major Projects staff regarding the Major Projects Procurement material standards and procedures.Assist in Procurement orientations and on-boardi ng of Major Projects staff.Review and provide advance recommendations for Project Procurement Strategies and Plans.Lead the development, implementation and management of policies, procedures and templates supporting the continuous improvement of material management within Major Projects.Collaborate with Business Unit Procurement, Project Controls, Accounting, Construction, Engineering and Project Execution personnel to accurately understand capabilities in terms of systems and processes.Outline material management procedures through the development of process flow maps.Prepare draft and final assessment reports of material management findings.First, the general requirements1. Stacking of construction material should be based on the amount of size, duration, supply and transportation determine dosage, use a long time, supply transportation is convenient, it should be phased in. approach to reduce the yard and warehouse space2. Construction site of a variety of tools, components, mat erials piling must be placed in conformism with the provisions of the position of the planar four Figure3. Position should select appropriate, easy to transport and handling, minimize secondary transportation4. Higher ground, solid, flat, backfill compaction in layers, have drainage measures to comply with the requirements of safety, fire5. Should be stacked according to the varieties, specifications, and set up the obvious signs to indicate the name, specification and origin6. Various material items must be stacked neatly.Second, the main material semi stacked1. Large tools, should one side get holdment put2. Reinforced should be neatly stacked, square wooden paving should not be placed in a wet and exposed to rain shower3. Brick should be small computer code into the stack, are not allowed to ultra-high from trench not less than 0.5m, to prevent collapse4. The sand piled mental block, stones should be different diameter sizes are stacked into a cube5. Various templates should be stacked neatly classified according to specifications, the ground should be flat solid, stack height generally should not be the ultra-high 1.6m the large template stored specifically designed to save shelf should be placed two large template should be used for face-to-face storage when stored floor construction, shall meet the homeostatic angle and reliable anti-dumping measures6. Concrete component stacking space should be solid, smooth, specifications, models stacked skids position to be correct, to be up and down to align the the multilayer components of skids, the pile position are not allowed to ultra-high the concrete blocking plate should be established insertion of frame interpolation put frame to be welded or lashing firmly to prevent collapse.ConclusionConstruction site materials management is one of the important link. To strengthen the management of the site layout, according to the different construction stages, materials and supplies changes, design changes, and ad just the position of the stockyard site in a timely manner, and keep the roads open, reducing the second out of luck. Strict union with the arrangement of stacked material with a flat-screen piles into the line, always clean up debris and garbage, and maintain the site, roads, tools and containers clean. The construction site must be carried out by the allied materials on-site materials management, material must pass the examination certificates member of the staff of the material running configuration to enable the production and management of working prevail.Materials management for the enterprise has an extremely important significance.In a certain period of time, material resources and funds are always wired, good materials science management can promote cost reduction.Which time the minimum material consumption, to the maximum economic benefits.
