Did you know that, according to McKinsey, almost 80 percent of large construction projects encounter delays or cost overruns? For those in the construction industry, these concerns aren’t new, they’re an endless challenge. But there’s actually a proven method to cut through wastefulness and keep a project on track. It’s called Lean Construction.
Lean construction stands out from conventional approaches by adding practical tools such as Just-in-Time delivery. Unlike traditional tactics that often consider each phase as distinct, insulated processes, lean construction delivers a holistic view, bringing together every team member, contractors, designers and tradespeople, into a cohesive planning process.
In this blog, we’ll include most everything you should know about lean construction, from its fundamental principles to everyday tools and techniques, so your company can produce results that set you apart from the competition.
What is lean construction?
Lean construction is a cohesive project delivery method that emphasizes collaboration among teams to maximize stakeholder value. Developed from lean production, the goal of this approach is to boost profit, innovation and productivity within a construction project.
The lean philosophy traces its beginnings in the work of Henry Ford and the production of the Ford Model T in the early 1900s but was firmly established especially by Toyota and their legendary efficient production system after World War II.
The success of Toyota and others led to lean production being implemented in other industries, with construction being just one on many to duplicate this method. Lean systems have also been embraced by companies across numerous other industries including retail, printing and customer service.
What are the foremost lean construction principles?
Lean construction is created on several key principles focusing on eliminating waste and improving processes. These principles include:
Value generation
At a high level, value generation is about providing a high-grade product or structure that meets or exceeds the client’s requirements and lasts a long time. More than simply delivering to specifications, lean construction attempts to uncover significance in projects so stakeholders can work toward a common goal.
Perhaps an example would make this clearer. Building a children’s cancer center is much more than putting up walls; it’s about delivering a healing space to treat defenseless members of society.
Streamline workflow
The principle of “flow” takes aim at a smooth, uninterrupted work progress throughout the project lifecycle.
A construction project comprises several processes, and each step must progress without interruption, for the project to be completed on time, on budget. To develop an efficient workflow in construction projects, the sequencing is crucial. For example, you can’t build a wall with columns without first building concrete footings.
To realize flow, everyone concerned needs to communicate openly with one another. It’s essential to inform everyone when a component of the project is running late or ahead of plan so that appropriate adjustments can be made to reduce incidents such as waiting and unnecessary inventory waste.
Waste reduction
Waste is a huge concern in construction projects with familiar forms including excess materials, uncalled-for motion, waiting times and mistakes requiring rework. One key reason for this waste is the misalignment between the design team and trade contractors working on the project. Lean construction confronts this problem by fostering early cooperation between these two groups.
Lean construction also pinpoints eight basic kinds of waste – defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion and over-processing. By tackling these issues, lean teams streamline work activities and concentrate on what really adds value.
Respect for people
Respect for people involves having faith in the know-how and skills everyone brings to the job. It’s shifting the viewpoint from blame to ensuring managers deliver the right information. Respect for teamwork and collaboration reinforce all the principles of lean construction.
Continuous improvement
True, these principles can have an enormous effect on an organization’s operations, production and profit, but they simply won’t make a difference if they’re not constantly applied and executed throughout a firm’s corporate culture.
Lean construction is not stationary. For it to be successful it will involve continuous monitoring and execution to pinpoint areas for improvement. It’s an endless process, and lessons learned are to be applied to future projects to enhance performance and foster continuous improvement.
Benefits of lean construction
Okay, you understand what lean construction is about. But you still need to know what benefits it can provide for your construction firm.
Here, then, are the chief paybacks of lean construction.
Efficiency and cost savings
Investing in lean construction principles can set in motion considerable efficiency and cost savings. Cutting material waste and worker time leads to lower costs while still providing a high-quality project on time, on budget. For a company applying lean construction for the first time, there will be costs, but the outcomes include a boost in productivity, reduced rework and waste and more effective working relationships.
Improved construction site safety
By its very nature, construction is an industry with major health and safety risks. While attentiveness and training have progressed in recent years, there are yet, on average, approximately 60,000 non-fatal injuries to construction workers every year. Yes, the fatal injury rate for the sector is 1.62 per 100,000 workers, but this is still four times higher than the general rate across all industries.
As a process focused on clear-cut communication and enhanced proficiency, lean construction can substantially upgrade the onsite safety of employees considerably by simply producing a safer work environment. By involving all stakeholders, promoting monitoring and endorsing risk management, applying lean construction principles can help construction firms keep their workers safer.
Improved resource allocation
Another of the major principles of lean construction is the effective application of resources. By using just-in-time delivery and other such resource management methods, lean construction helps make sure that materials and equipment are there when needed, reducing any unnecessary stockpiling. This not only cuts costs related to storage and handling but also reduces the possibility of material wear and tear or even loss.
Enhanced project scheduling
Lean construction methods encourage the employment of thorough and accurate project scheduling which is critical for making sure that all tasks are completed on time, on budget. By closely keeping an eye on the project’s progress and making adjustments as required, project managers can sidestep delays and keep the project on its intended timetable.
Early issue detection and resolution
One of the other significant advantages of lean construction is its emphasizing early detection and solution of problems. By including all stakeholders in the project from the very beginning and promoting open communication, would-be issues can be recognized and addressed before they become bigger problems. This constructive approach helps to avoid costly rework and make sure that quality is sustained throughout the entire project lifecycle.
Improved sustainability
Embracing lean construction can also help the industry deal with its role in the climate crisis. Cutting down material waste is a pivotal rule of lean projects, and by focusing on tweaking collaboration, constantly looking out for opportunities to get better and only producing what’s needed will help lower the environmental harm created by a company’s construction project.
Improved customer and employee satisfaction
As highlighted by the principle of value generation, the final result is key to the successful implementation of the lean construction model. By working closely with both customers and stakeholders, construction managers help make sure the project is completed and meets their expectations. It’ll also help keep everyone on time, on budget, something that should please all involved.
It's not simply project stakeholder and customer satisfaction that you stand to earn from the lean method – employees engaged in the project will have a better experience, too, thanks to improvements in health and safety and a drop in project delays.
Steps to implement lean construction methods
Great, you’ve been convinced that you should look into the lean construction method. What steps do you need to consider to make this happen?
Adopting lean construction methods may seem intimidating, but construction firms can begin with incremental changes. Here are some practical steps to get started.
1.) Engage your team
Lean construction demands a cultural shift and buy-in from your team. It’s both a method of business and a philosophy.
Begin by educating team members and subcontractors about these lean principles and how they benefit all involved. Promote open communication and teamwork, establishing an environment where team members feel empowered to recommend improvements.
2.) Identify and eliminate waste
Conduct a detailed investigation of your operations to detect areas of waste; this could include:
Once waste is recognized, employ measures to tackle these inefficiencies. For example, adopting just-in-time (see #3 below) material delivery can slash storage costs and reduce waste.
3.) Implement just-in-time delivery
As mentioned, Just-in-time (JIT) delivery is one of the main features of lean construction. JIT delivery entails ordering and receiving materials only when they are needed. This method lessens the need for sizeable on-site inventories that can tie up capital and enhance the threat of material waste due to damage or theft.
4.) Standardize production processes
Standardizing processes is another technique to cut costs and tweak efficiency. Standardization is a lean practice that includes creating uniform processes and systems for repetitive tasks to help reduce errors, minimize rework and accelerate construction.
Construction managers can employ standardization by designing specific procedures for each task and making sure all team members receive proper instruction on these processes.
5.) Use Building Information Modeling (BIM)
Building Information Modeling (BIM) is a digital tool that offers an all-inclusive 3D model of a construction project, allowing improved visualization, coordination and forecasting. BIM can help construction managers pinpoint would-be problems before they surface, enhance material usage and increase teamwork among all project stakeholders.
6.) Employ technology to streamline processes
Employing construction management software can also help businesses apply lean practices more successfully. These tools can help with scheduling, measuring progress, managing subcontractors and overseeing resources in real time, lowering the chances of postponements and cost overruns.
7.) Focus on continuous improvement
Embrace a mindset of continuing refinement, often referred to as Kaizen (Japanese for change for good). Routinely examine project performance to uncover areas for improvement.
Foster an environment of ideas and feedback from employees and stakeholders to identify new prospects for efficiency.
Overcoming challenges
Obviously, transitioning to lean construction is not short of its challenges. Opposition to change, inadequate resources and a shortage of know-how can hamper progress. Businesses can speak to these issues by:
Keep in mind that implementing lean construction principles can provide a great approach for improving profitability and enhancing long-term success and it is frequently a far better approach than focusing on just a boost in revenue.
By cutting back on waste, cultivating teamwork and fostering a culture of continuous improvement, businesses can offer greater value to their customers while slashing costs and boosting efficiency.
The pathway to lean construction will demand effort and commitment, but the paybacks -- improved profitability, better project results and a more robust business -- are well worth it.
