LEAN AND BIM: The changes that construction is experiencing
Construction is currently livingtwo important changes, the first of them is theadoption of a "lean" strategic and operational thinking,focused on the continuous elimination of waste, maximizing the added value to the customer; and thetransformation of processes in organizations towards the use of new technologies such as BIM,seeking to facilitate communication, coordination and transparency of our processes and our projects.
Both changes are aimed at increasing productivity, profitability, improving our quality, facilitating and simplifying projects, among others... Unfortunately, many times the interests of both changes collide due to theconfusion and misunderstanding... On your side,Lean is confused with only applying the Last Planner System and BIM is "translated" as one more software to make plans and renders ("The Revit").Both interpretations far from reality.
Lean is about giving only what is needed (satisfy the needs of our external and internal customers),only when needed(ensuring a flow to achieve the objectives in the planned time), as the customer needs(maximizing the added value, which can be cost, time, quality, functionality, among others)and in the amount needed(taking advantage of resources to avoid cost overruns or unnecessary efforts).
Civil engineer, graduated from Tec de Monterrey (Guadalajara Campus), former collaborator of Grupo Sohersa, founding partner of Kyodai Consultores, specialist in the implementation ofnew technologiesand ofproductivity increasewithin construction with a focus onreal-time control.
I seek to bring the Lean culture and the use of BIM to any company with which I have the pleasure of collaborating.
Presentation
On your side,BIM is an intelligent, multidisciplinary and collaborative processwhose function is to create adigital modelthat encompasses thegraphic information(3D Model) and not graphic (Data) of the architectural, engineering, design, and construction characteristics of a project
.
This digital model serves as an integrating platform for the project from whicheveryone involved is part and can extract the informationfrom the conception of a project to the end of its useful life cycle.
both changes complement each other, especially in the early stages of the project:
Lean helps define, align and quantify Project Success Criteria(Examples: Total cost of ownership, Execution time, Quality / user satisfaction, Energy efficiency / sustainability, A unique design, A buildable, operable, useful and functional property, among others),which will define the Project Design Criteria(what the client finds value from a design perspective in order to deliver a concept to their liking)that will be the basis of our Preliminary / Conceptual Design,in which we seek to achieve the Concept and Feasibility that meets the objectives and requirements of the client.
BIM,through its dimensions and functionalities,allows us to generate and evaluate a greater number of design alternatives (concepts) and determine their feasibility(technical, economic, etc.), thanks to computational modeling (through tools like Revit), design automation (through tools like Dynamo) and generative design (through tools like Project Refinery). In addition to this, by generating tours and virtual environments we can impact and show the client their project, which allows them to understand and analyze it more effectively, which will help us tofind the “champion”the client's.
This and many other interactions, both from thedesign perspectiveas of theperspective of the execution (work),We will be discussing them in detail in future posts, stay tuned to the social networks of Sohersa Group BIM Development and Kyodai Consultantsto find out about the new trends in technology and processes that are revolutionizing the construction industry.

Inclusion of structural engineering in the BIM methodology
The general perspective that exists about BIM is that it is a great project visualization tool, another group of people has the vision that it is useful for this and also to quantify. This very limited vision of BIM is shared by many (if not the vast majority) structural colleagues, at least speaking of Mexico.

Chapter 2: What is BIM?
Today, the notion of BIM has wrong views caused, in my humble opinion, by the interests of the different actors in the AECO sector, which try to bias the global understanding of what BIM is, so it seems to me a good idea to start with try to explain what BIM is NOT.

Chapter 1: Digital Construction
Nowadays when we hear about digitization or virtuality, they are words that we hardly associate with construction, engineering or architecture. This is because we who are dedicated to thebuildingwe continue to build the same as more than two thousand years ago!!! This is when the reader thinks, "This woman has lost her oremus!
