Supply Chain Management in Construction Industry

March 19th, 2012

tosviol.com - Generally the construction industry life cycle starts from the idea, planning, design, implementation, operation and maintenance, and end with the reconstruction / demolition.

At each stage of the construction life cycle is supported by a typical supply chain system. Supply chain involving multiple stakeholders dominates the idea stage. Supply chain expertise and support services are widely used investigative tools at the planning and design. At the stage of implementation, maintenance, and reconstruction / demolition involves a lot of material supply, technology, equipment, and construction workers.

Typical of Construction Supply Chain Systems

Generally the structure of the construction supply chain system consists of two parts, namely the organization on the “demand” and the organization on the “supply”. Both sides of the organization are linked by a contract between the principal in charge of construction activities with service providers.

Primary responsibility activities can be the owner of the project, representatives of the owner, or developer. The use of project funds are financed by external funding sources or project not directly from the owners must be accountable to the donors. For infrastructure projects whose products will be used by the public, and the building sold or leased to tenants, in charge of the construction project should be accountable for the product to users, residents, the new owner, and / or the public.

Provider of construction services that directly relate to the person in charge of activities is a provider of construction services that the contractor, construction manager, or developer; provider of consulting services that architects, engineers, cost analysts, and / or project manager.

The next tier supply chain consists of suppliers, agents, providers of specialist services and / or supporting manufactured the tier above it.

Typical of construction supply chain system can be described in the following scheme;

Materials and Construction Equipment

tosviol.com – Input resource constructs consisting of equipment, material, time, technology, human resources, costs, provider of construction services, suppliers of construction inputs, and the guarantor of the construction.

Today the management of construction resources is more focused on controlling costs and time to produce a product with quality construction that has been set. Organizers of construction have been very adept in making a proposal of activities which in the main substance is the cost and time.

In the implementation, cost and time well-controlled so as not to exceed a predetermined limit. Implementation has been prepared in good control system so that costs can be accounted for professional use.

Development of national construction organization that so rapidly has demanded the organizers pay more attention to the construction for other construction resources. In the past, the value of construction activity is relatively small compared with the input of available construction resources. Materials, human resources, technology, and equipment are considered abundant to support the construction of investment each year.

Problems encountered in the field due to the lack of more cost and time delays of implementation. However, along with the continued construction that become larger but on the other hand the material availability, human resources, technology, and equipment are limited make a maintenance construction critical path is no longer just in the aspect of cost and time. Therefore, the command of material chain and construction equipment in the future will more and more important is no longer just an idea but a necessity.

Implementation of Supply Chain System

tosviol.com – Manufacturing has grown along with the development of human civilization. The development is faster after the industrial revolution in the 18th century in England.

The results of the industrial revolution reached its peak in the 20th century, after World War II, which is characterized by the occurrence of very intense competition in the marketing of manufactured products. To meet the increasingly stringent requirements of the product in accordance with market demands, manufacturing control system implementing the supply of raw material input system and manufacturing process. The supply system is a network of interrelated, forming a supply chain. Implementation of supply chain systems in manufacturing has been able to improve process efficiency and better ensure product quality.

Based on the results of a study of the Lean Construction Institute, manufacturers have managed to achieve the level of value-added of the products by 62%, and suppress byproducts such as waste disposal to 26%. The achievement was very high compared to the field of construction, namely the achievement of value added is only 10% and the level of exhaust waste production by 57%.

An inefficient construction industry, and the waste disposal is relatively large due to the construction industry is fragmented. Another impact of this condition is common in the construction industry increased implementation costs, delays and disputes.

Based on experience in the manufacturing, supply chain management system sought to be applied in the construction industry in order to increase value-added products and reduce product waste disposal. Efforts are made by way of organizing lean construction. Of course, the implementation effort is not easy because of the characteristics of the construction industry is much different from manufacturing.
