What is BIM?

Building Information Modeling (BIM) is a collaborative work methodology for creating and managing a construction project. The objective is to centralize all the information of the project in a digital model created by all the agents involved.

BIM advantages

It allows multidisciplinary work, integrating and sharing information in real time. In this way, collaboration between clients and designers is improved during the construction phase.
It allows the interference check thanks to a complete model with all the information.
Knowledge of the energy impact of each of the materials that make up the work. In this way, the buildings are more integrated with the environment, sustainable and efficient.
Integration of 2D and 3D, improving
the project vision.

At Calaf Constructora we are specialists in the phases of:


Technical office collaborates with the client and the engineering, making calculations, construction details and adjusting the BIM model to guarantee the construction.


Analysis, documentation and manufacturing; coordination and auditing of the project to guarantee the viability of the construction process and execute the work with the maximum possible agility.


4D / 5D construction, logistics and construction, maintenance and renovation. We do the planning of the work and the economic control to optimize the costs. We coordinate the entry and exit of the work collaborators and the execution of the security plan.

What is LEAN?

“Reducing activities that do not add value means producing the right product, with the required quantity and at the right time. Producing exactly what is needed and nothing more”

Taiichi Onho, Toyota engineer and creator of TPS.

It is a philosophy that is based on a methodology that implies:
Reducing or eliminating activities that do not add value.
Minimizing those activities that do not add value, but are necessary.
Promote activities that do add value.
To carry this out, it is mandatory to have an open mind, a global knowledge of the organization, the ability to detect problems and opportunities, and understand continuous improvement as an endless process.
What is LEAN based on:
1. Implementing and studying the best relationship between people, machinery and materials
2. Identifying and eliminating variability (mura), saturation (muri) and waste (muda).
3. Achieving standardization, simplification and specialization.
Last Planner System:
It is a collaborative project planning tool within the Lean Construction methodology. It allows detecting problems and acting from the root and taking measures to guarantee the best production and quality that each client deserves.
