What does lean construction stand for?

Lean construction is a way of designing production systems in a construction environment with the aim of decreasing time, effort, and a waste of materials. Lean construction ensures that a project is quickly done, and lower costs are incurred during the building process.

How do you lean in construction?

6 Principles of Lean Construction

  1. Identify Value from the Customer’s Point of View. The traditional approach to construction focuses on what the customer wants you to build – what’s included in the plans and specifications.
  2. Define the Value Stream.
  3. Eliminate Waste.
  4. Flow of Work Processes.
  5. Pull Planning and Scheduling.
  6. Continuous Improvement.

What are lean construction tools?

In general, lean construction tools are intended to improve the delivery systems and processes by minimizing wastes, increasing productivity and health and safety and overall, achieving client’s requirements (Hannis-Ansah et al., 2016).

What are the 5 principles of lean?

According to Womack and Jones, there are five key lean principles: value, value stream, flow, pull, and perfection.

What are the six principles of lean?

The Key Principles of Lean Six Sigma

  • Focus on the customer.
  • Identify and understand how the work gets done (the value stream).
  • Manage, improve and smooth the process flow.
  • Remove Non-Value-Added steps and waste.
  • Manage by fact and reduce variation.
  • Involve and equip the people in the process.
  • Undertake improvement activity in a systematic way.

Is Lean used in construction?

As a result, lean -based tools have emerged and have been successfully applied to simple and complex construction projects. In general, lean construction projects are easier to manage, safer, completed sooner, and cost less and are of better quality.

What are principles of construction?

The Five Construction Principles have been established so that the five elements: environmental protection, safety, speed, economy, and aesthetics, conform with a balanced regular pentagon.

What is meant by lean concrete?

A concrete with cement content less than about 10 % of the total contents can be called lean concrete. More the aggregate to cement ratio, the leaner is the concrete. As the lean concrete uses a lesser amount of cement, it is used in fillings or under the foundations so that the structure is protected from the soil.

Is SMED a lean tool?

SMED is a tool in Lean used to reduce the amount of time it takes to change from running one process in an operation to running another.

What are the basic lean tools?

Lean Tools and Their Applications

  • Bottleneck Analysis. How many times have your projects gotten stuck somewhere between development and delivery?
  • Just-in-Time ( JIT )
  • Value Stream Mapping.
  • Overall Equipment Effectiveness (OEE)
  • Plan-Do-Check-Act ( PDCA )
  • Error Proofing.

What is not advantage of lean construction?

Some argue against Lean Construction as they believe in order to build so quickly and efficiently, corners are being cut. For example, less than appropriate materials are being used and won’t last as long as traditional materials, meaning the project itself won’t hold the same longevity.

What are the disadvantages of lean production?

Disadvantages of Lean Manufacturing

  • Equipment Failure. Lean has very little room for error.
  • Delivery Inconsistencies. In correlation with equipment failure, lean manufacturing can lead to delivery inconsistencies.
  • Employee Dissatisfaction.

How can prefabrication benefit Lean projects?

Prefabrication of building components is often used by contractors to reduce costs. If employed effectively, prefabrication can enable process standardization, shorten lead times, improve quality control, and reduce material waste.
