▷ What is lean construction, methodology and principles

Lean Construction in the sector

The term lean construction or construction without losses is a philosophy that appears as an alternative to improve the competitiveness of construction companies. The productive market is strengthened based on the optimization of processes.

This model is focused on changing the philosophy of the construction sector market.

Lean construction encourages the development of new strategies in the way of working in the construction field to give value to the final product.

Principios de lean construction

When it comes to the principles of lean construction, tools are proposed to eliminate the sources of losses and methodologies so that increases productivity taking advantage of all available resources and optimizing time.

Among the losses that are established in lean construction are:

  1. Transportation
  2. Timeout
  3. Talent not used or misused
  4. Overproduction
  5. Inventory
  6. Defects
  7. Overprocessing

Principles of lean construction

The main thing for this type of tool is customer satisfaction giving value to optimized processes by continuously improving based on its principles.

The client

It is the goal in the entire lean construction philosophy. The solution to the problem presented by the client is provided by giving them a desired product in the agreed conditions and time, with the quantity and quality specified in the order.

When applying lean construction in Spain, the client’s requirements are valued to guarantee their satisfaction.

At the same time, the market is investigated by making evaluations after the delivery of the final product.

Unnecessary activities

Everything that does not add any kind of value to the final product must be eliminated: activities without value must be stopped or changed, alternative processes must be optimized and the reduction of waste in the process must be equal.

Minimizing the number of steps in a process can be done with the lean construction philosophy implanting production cells, or having prefabricated elements in advance.

Steady improvement

Every process can be improved by optimizing time and acquiring new methodologies in some or all of the phases that comprise it. This is beneficial both for the working structure of the business and for the final product.

In addition, the process must be continuous, flowing in such a way that the deadlines for compliance are within the stipulated time. Wait times are considered a waste of opportunities and a waste in the construction lean methodology.

Time

The optimization of the time cycle involved in a work in lean construction Spain, solves the production process and its standardization in many ways, reducing the actions that do not add significant value to the project so that deliveries are on time.

Value added

When applying lean construction in Spain, it is important to give a little more to the customer without compromising costs. One way may be by customizing the final product that is offered.

Allowing more value to be added to the process with constant updates, training and new information motivates everyone involved to improve to reduce execution time.

Methodology of lean construction

With the application of the lean construction methodology the design and operation process of a project is done together to work on the processes reducing losses and improving the control system.

The final objective of the lean construction methodology is to reduce the time invested in actions that do not add value to the final product to the maximum.

Waiting for materials or lack of equipment, or having delays due to some poorly executed activities are some of the inconveniences that are avoided by applying lean construction. In the same way that there are problems in the planning of the work site or the transfers.

metodologia lean construction

To apply this methodology a diagnosis must be made of the activities and how they are executed, the effective time and what it contributes to the product.

Having these data is statistically analyzed to know the magnitude of the losses before effectively applying lean construction.

With this information, actions are carried out to reduce losses and increase productivity, applying the strategies directly on site.

Lean construction in Spain

Another process within the methodology applied in lean construction in Spain is when the activities carried out between the different companies are compared. This serves to be able to identify process improvements and apply them in future actions within the work itself.

With lean construction you need to be focused on efficiency, as well as on collecting the necessary data to later analyze and improve processes.

Since lean construction has been used in Spain, productivity has increased in many projects at the same time that costs are reduced and delivery time has been saved by eliminating work stoppages.

This allows companies to be more competitive by applying the lean construction methodology from any of its phases, engaging workers in the improvements obtained.

Benefits of relying on Lean construction

Among the benefits obtained with this philosophy in construction is avoiding extra costs and unexpected expenses.

The waiting time is controlled, whether for materials, information logistics or equipment delivery. It is also possible to anticipate the problems that arise or the restrictions that you may face, avoiding unnecessary delays.

There are no stagnant or blocked resources or money that are not being used for the production and profitability of the work.

Detecting failures from their source prevents them from recurring. From this learning each process grows and improves.

They even incorporate all the entities that are part of the process, builders, suppliers, teams, who share information, benefits and decisions in a fluid way for the benefit of all.

beneficios lean construction

As far as possible without compromising quality, the components of a product are reduced, as well as the number of steps to flow the amount of materials or information required.

For competitiveness to be within the standards and be productive for investment, process efficiency must have excellent quality, quantity and price.

The transparency of the process lies in improving the organization and quality of production removing obstacles, clearly using the tools and visual control of the project.
