According to the greatest exponent and investigator of this doctrine, Lauri Koskela, the Project Management based on Critical Path analysis (PERT diagrams) has been overtaken by time as an application methodology in respect with customers’ need.
Why to acquire Lean Construction certification?
The solution is called Lean Construction and it is a concept developing in Spain since the beginning of 21st century. It stems from the systems creation need at construction industry that reveal and solve the occuring problems and to spread that information inside the organization itself.
Let us remember that ‘Lean’ methodology applied to any field with their respective features is always based on the same principles: identify, value, correct, improve and repeat. All of that with the only purpose of maximising added value at core activities and delete those that generate few added value or diminish value to procedure.
Lean Contruction follows that same continuous improvement principles of Lean Manufacturing but at construction plans management, with the application of tools and systems such as: Last Planner System (LPS), the 5s, the A3 report, Value Stream Mapping, Kanban, Lean Project Delivery System, accomplishing construction techniques productivity increase and improving the project profitability.
The LPS is a work in building methodology that changes the course of scheduling and control of the project, reducing uncertainty and possible alterations at project’s management.
5s technique
Is a Japanese management methodology based on 5 simple principles, corresponding to the name initials that in Japanese designates each of its 5 phases: Seiri (classify), Seiton (organise), Seiso (cleanliness), Seiketsu (standardise), Shitsuke (habit). The objective is focused on the achievement of better organised workplaces, more ordered and cleaner persistently to reach a higher productivity and improvement at work environment.
A3 report
Is a report on a A3 canvas in which it’s reflected the solving problem procedure that is causing at the advance on planning and graphically helps as a making-decision tool. It has 7 points:
Precedents: context in which the problem is understood.
Current situation: it places the main problem and values it.
Causes’ analysis: detailed analysis and main problems deliberation.
Improvement objectives: according to operational strategy circumstances.
Improvement measures: solution schema with the problems and people implicated.
Plan of Action: measure plan and evaluation plan for these measures.
Results Monitoring: measurements application to not deviate the established objectives.
Value Stream Mapping
Is the value chain mapping, it visually delivers the materials and information flow and quantifies it. It also gives us information to know how each activity is providing added value to the product and which activities could be dispensable or which ones could be accomplished with less resources.
Is an information system based on indicators that control production of required materials at necessary time and quantity in each of the processes. A Kanban card is a permit to produce and/or moving stocks used for controlling them, revealing problems or chances of change. It’s designed to avoid overproduction and to guarantee that components go from a sub-process to the following one in the correct order.
IPD (Integrated Project Delivery)
Is a management projects’ approach based on callaborative contracts that integrate people, systems, organisations and practices into a process that makes use of talent and the points of view from all the parts to enrich projects’ results, adding value for the customer, restricting expenses and optimizing efficiency through all design, production and construction phases.
