Beam structure
Storyboard 
The problem arises because the preliminary design defines the general structure of the beams, while the SIP structure design does not specify how they should be assembled. Therefore, it was necessary to define the assembly according to the SIP design, ensuring that it corresponded to the house plans generated in the preliminary design. This required making some adjustments as the structure was being built, ultimately achieving a final result that reflected the original design.

Lack of clarity in design
Description
On May 16th, the construction manager mentioned that he was unclear about how the beams should be mounted and sent an interesting photo showing the central beam mounted on top of the SIP panels. Additionally, another beam can be seen on top of the SIP, with others protruding:
Clearly, the assembly does not align with the plans, although it should be noted that the plans do not clearly define the mounting of the main beam. It is likely that this problem arose because the work proceeded based on the preliminary project, while the final project would have defined this point more explicitly. On the other hand, the SIP panel plans do include the definition, so the structure is fully defined.

Definition of beams according to plans
Description
According to the plans, the beams do not protrude but rest directly on the mezzanine. This is important as it helps stabilize the mezzanine. Additionally, in the center, the original design assumes that the beams support each other without a main beam being visible. However, the idea of using a central beam provides more stability to the structure, making it a highly recommended modification:
The challenge, then, is how to integrate the beam into the section of the SIP walls of the mezzanine.

Center beam solution
Description
If you look at how the SIP panel structure defines the roof, you will notice that the central beam is not considered, but only a connecting beam between the panels:
However, this solution contradicts the design in the plans, where this beam does exist, and in the case of the study module, it must allow for lifting objects to the attic. Additionally, its inclusion helps support the lateral beams and stabilizes the entire roof. Therefore, it must be included as indicated in the plans and made compatible with the SIP system design.

Center beam assembly
Description
The way to integrate the presence of a central beam with the SIP model is to embed it into the mezzanine walls as shown below:
It is important that:
The beam rests on the beam between the panels and not on the pressed wood of the panels, as these could detach from the core.
