5 Advantages of Applying Lean Principles in Integrated Project Delivery

Commercial buildings are inherently interdisciplinary structures. Achieving high-performance outcomes and positive occupant experiences requires architectural design, construction, engineering systems, and interior design to work together cohesively. Yet many architecture and construction firms today operate from a hyper-specialized and fragmented approach to building development. This mindset stifles innovation and creativity, slows project timelines, and often results in unplanned costs and risks.

 At TONO Group, we are transforming possibilities within the design-build process guided by the straightforward belief that collaboration creates superior outcomes.

From small-scale fit outs to expansive developments, our process is rooted in an Integrated Project Delivery (IPD) approach. The American Institute of Architects (AIA) defines IPD as a process that integrates people, systems, business structures, and practices to collaboratively harness the talents and insights of all participants.[i]

Our IPD process revolves around five integrated in-house family of businesses. These include real estate consultation (RELO), development (RETRO), architectural and interior design (TONO), construction (PROTO), and curated (FF&E) furniture, fixtures & equipment (DECO).

Every team works together using lean principles to guide their workflows, ensuring each project is optimized for value and quality. In practice, construction management, design, and engineering coordinate from day one to maintain alignment and momentum.

Enhancing IPD with Lean Principles

Lean principles in architecture and construction are developed around six guiding philosophies[ii]:

1. Respect for people
2. Optimize the whole
3. Eliminate waste
4. Focus on flow
5. Generate value
6. Continuous improvement

Implementing these philosophies into the Integrated project delivery process brings significant improvements throughout the entirety of a project’s lifespan. Improved collaboration ensures faster project delivery, better cost savings, and higher quality outcomes. Combined, this integrated approach delivers the ultimate outcome: meaningful client partnerships and truly inspired placemaking.

Here are five advantages of applying lean principles in integrative project delivery.

Improved Collaboration

For successful commercial building projects, it’s essential to involve the right experts from the start and keep them engaged through each phase.

Traditional construction management and project management approaches leave teams and stakeholders in silos. This fragmented process often means each team only begins work once the previous component is complete.

For example, construction leaders start their tasks after architectural planning is finished, and interior design comes into play once the building is done.

This often results in overlapping work, change orders, unexpected costs, and missed opportunities to enhance the project. A unified process breaks down these barriers and invites all teams to communicate and share their expertise holistically as they work toward a common goal.

This approach helped bring the vision for The Lititz Shirt Factory, a multi-level entertainment venue, to reality. TONO Group was selected to transform the abandoned 90,000-square-foot, historic warehouse into a modern, community gathering space. Working as an integrated entity, in tandem with the project’s proprietor, TONO Group provided consultation on real estate development while leading architectural design and construction.

By using a well-organized method, the project was successfully carried out to truly capture the owner’s vision of restoring and transforming the historic building.

Faster Project Delivery

Better collaboration leads to quicker decision-making and earlier issue resolution. The IPD process and lean principles ensure that all team members are aligned on expectations, tasks, and timelines. This can reduce and even eliminate rework, duplicate activities, and downtime that slow the progress of commercial building projects.

The Lean Construction Institute estimates that 70% of commercial building projects are completed past deadlines when traditional delivery methods are used. With interdisciplinary teams working together, information and expertise are shared early and throughout the process. Work is initiated in parallel to minimize disruptions, and issues can be identified sooner to prevent downtime.

This benefit was realized during the building transformation of Eye Check Health & Vision. The boutique optometry practice needed to embody the brand’s luxury retail experience while maintaining adequate workflows for patient care.

By providing a single-source experience that combined all areas of architecture, construction, and design, TONO Group was able to unburden the client from day-to-day project management and successfully complete the fit out within the constraints of a short deadline. The result is a distinctive environment where patients’ needs can be served in comfort and with warm reception.

Cost Savings

Lean construction practices are rooted in waste reduction. Teams can do more with less by optimizing resources and collaborating early across construction management and design disciplines. Centralized tools like Building Information Modeling (BIM) platforms provide transparency and allow teams to evaluate cost implications as decisions are made. This allows conflicts to be identified early, reducing costly change orders and preventing problems before they happen.

Recently, TONO Group worked with CrossNet Ministries, a non-profit organization that provides transitional housing, career counseling, youth programs, and resources for those facing food insecurity. Maintaining their budget was key to transforming a 27,000-square-foot former manufacturing warehouse into a meaningful space designed to meet the needs of the community. Using an IPD approach, TONO Group provided property evaluation, architectural design, construction, and interiors to drive value through every aspect of the project.

Higher Quality Outcomes

Ensuring high-quality outcomes depends as much on collaboration as it does on technical expertise. When lean practices are combined with an IPD process, they establish a framework where all stakeholders are engaged early and continuously throughout the lifespan of the project. This engagement fosters clear communication, transparency, and accountability to ensure that every decision is aligned with the objectives and goals of the project.

Through a structure of continuous feedback, teams contribute their expertise and actively participate in problem-solving. Challenges are addressed collaboratively using focused experimentation and iterative refinement. Instead of relying on siloed knowledge, the collective insight of the entire project team drives solutions that are both functionally accurate and meaningful.

Increased Client Satisfaction

Occupant experience is central to a building’s value. Similarly, we believe that the client experience is central to a successful design-build project. Combining our interdisciplinary expertise with a framework of lean principles, we’ve engineered our IPD process to not only deliver inspired places but also enhance client relationships.

 At TONO Group, we follow these practices because we believe it’s the right thing to do: clear and honest communication, maximized resources that maintain budgets, and innovative thinking that delivers your vision on time. We’re humbled by each opportunity to grow in partnership and develop buildings that elevate communities and neighborhoods around the country.

Through thoughtful practices, a strong reverence for place, and a people-first commitment, we’re on a mission to reimagine the built environment. And we can’t wait to learn about your vision. Contact us to start a conversation about your vision for your next project.
