Today, we want to discuss an often undervalued lean construction technique鈥攖he 5S methodology. Organisations worldwide are adopting 5S because it:

• Is relatively simple to implement and doesn鈥檛 require complicated training
• Helps reduce and eliminate waste on construction sites
• Increases everyone鈥檚 involvement in projects
• Improves safety and reduces uncertainty
• Lays the foundation for implementing other lean building techniques

Let鈥檚 explore the lean 5S technique and how to implement each step at your worksites.

The 5 Ss of lean construction management

Sort, set in order, shine, standardise, and sustain鈥攔eferred to as 5S鈥攊s at the core of every lean building technique. By following the 5S lean construction management workflow, project managers and contractors can reduce on-site waste, increase productivity, and instil a quality culture.

Let鈥檚 break down the steps of lean 5S.

1. Sort

The first 5S principle focuses on identifying unneeded or unwanted items before they become an issue. It follows the 鈥渏ust-in-time鈥� mindset: Only keep the materials and equipment that you need, in the quantity you need, when you need them.

This means asking three questions about every item on your worksite:

• Do we need it?
• Do we need this much of it?
• Does it need to be right here, right now?

After answering those questions, there are four possible outcomes for each item:

• Tag and date it鈥攊f the item goes unused for a month, it鈥檚 probably not necessary to keep on-site
• Discard, sell, or recycle the item
• Move it to a different location
• Leave the item in its current location if deemed necessary

2. Set in order

This 5S lean building technique is all about organisation鈥攕etting every item in order so that anyone who needs it can find and use it easily.

Set in order is so simple that we can define it in a single sentence: Create a place for everything, and keep everything in its place.

After sorting your materials and equipment to remove unnecessary items, it鈥檚 time to put them in order by:

• Identifying appropriate locations to store them
• Determining each one鈥檚 ideal location
• Placing (and keeping) each one in that location in their necessary quantity

3. Shine

Next, we have shine, which helps keep worksites clean by focusing on the health and safety of both the construction site and the people working on it.

Keeping each work area clean and orderly consists of:

• Determining what areas need to be cleaned
• Dividing up those areas and assigning different workers to each one
• Creating a plan for when and how those areas should be cleaned
• Using the previous step (set in order) to store cleaning supplies in a way that makes them easy to find, use, and return
• Incorporating a cleaning inspection schedule

4. Standardise

The fourth step of the lean 5S techniques focuses on creating a set of processes to maintain the three previous steps. A standardised state exists when you properly maintain sort, set in order, and shine.

There are two necessary components for creating standardisation:

• Make it clear who鈥檚 in charge of maintaining the conditions of the first three steps
• Implement daily maintenance routines to avoid setbacks

The person in charge of 5S maintenance should also work on preventing disruptions to sort, set in order, and shine by asking questions like:

• Why are we bringing unnecessary items on-site?
• Why aren鈥檛 equipment and materials being returned to their proper locations?
• Why are certain areas of the worksite repeatedly getting dirty?

5. Sustain

The final step of 5S in lean construction management consists of forming habits to maintain the previous four processes. It鈥檚 also the step where most organisations fail: It鈥檚 easy to create new procedures and tell everyone to follow them, but the challenge comes from instilling the discipline to sustain them.

To sustain these good habits, you can implement:

• A to support sort
• Posters or other visuals to support set in order
• A clear, accessible schedule to support shine
• Regular inspections and reviews to support standardisation

3 Tips for implementing 5S lean building techniques

You can apply lean 5S to your project at any time, but it鈥檚 important to implement the steps in the order listed above鈥攅ach step builds upon the previous one.

Follow these three tips to make applying the 5S techniques to your next project go smoothly:

1. Start with yourself

Respect is a huge part of lean principles, and it鈥檚 just as important when starting a 5S program. Take some time to learn the 5S process yourself so that you fully understand each step鈥攊t will make teaching your team and implementing the techniques successfully much easier.

2. Go for small wins

When you onboard your team to the 5S process, answer their questions, ask your own, show examples of each step, and focus on teamwork and communication. Each project and person will have nuanced differences鈥攚hen you start implementing lean 5S, it won鈥檛 go perfectly; focus on each small win to encourage continuous improvement.

3. Be patient

People are imperfect. Projects are imperfect. Don鈥檛 expect a flawless 5S program on the first day or even in the first year鈥攂e patient, listen to your team, and find opportunities to turn mistakes into a learning experience for everyone involved.
