IPD & LEAN Construction
Our IPD process is Lean Construction - The Perfect Marriage
What is lean construction?
LEAN Construction is a production management based approach to project delivery – a new way to design and build capital facilities. Lean production management has caused a revolution in manufacturing design, supply and assembly. Applied to construction, Lean changes the way work is done throughout the delivery process. Lean Construction extends from the objectives of a lean production system – maximize value and minimize waste – to specific techniques and applies them in a new project delivery process. As a result:
- The facility and its delivery process are designed together to better reveal and support customer purposes. Positive iteration within the process is supported and negative iteration reduced.
- Work is structured throughout the process to maximize value and to reduce waste at the project delivery level.
- Efforts to manage and improve performance are aimed at improving total project performance because it is more important than reducing the cost or increasing the speed of any activity.
- “Control” is redefined from “monitoring results” to “making things happen.” The performance of the planning and control systems are measured and improved.
The reliable release of work between specialists in design, supply and assembly assures value is delivered to the customer and waste is reduced. Lean Construction is particularly useful on complex, uncertain and quick projects. It challenges the belief that there must always be a trade between time, cost, and quality.
IPD & LEAN CONSTRUCTION
IPD is uniquely suited to put these principals into practice, because we have solved the contractual issues that prevent true collaboration and the sharing of ideas, materials, and manpower.One of the cardinal principles of LEAN Construction is that when you optimize a single step in a process you de-optimize the whole.
Unfortunately, traditional construction contracts divide all the entities on the project into separate camps with each intent on optimizing its own part of the project, thus de-optimizing the whole. Our cost and profit sharing approach eliminates traditional contract barriers and incentivizes team members to act unselfishly and make “project” decisions rather than “trade” decisions.
We believe utilizing the IPD process and the principles of LEAN Construction that we offer two main advantages over the traditional design-bid and design-build processes.
Reduced Waste: We have reduced waste in the design and construction process by up to as much as twenty percent.
Increased Reliability of Planning: Eliminate the inability to plan work reliably and effectively by removing the unpredictability of the work flow.
Key LEAN TENETS
- Optimizing a part may de-optimize the whole
- Focus on delivering value
- Allow value to flow by eliminating obstacles
- Eliminate things that don’t add value
- Create pull production
- Strive for perfection at every level
- Value engineering is built in from the start
- Work can be managed to optimize project schedule goals rather than trade workforce goals
- Workers can be shared across trades
- Duplicate work/equipment can be eliminated.
- New ideas flow freely
