PCMO Phasing and formwork’s rotation

In this article I will present the work of Ronan LECAVORZIN. He took charge of recovering the model and exporting it so that he could perform the phasing and rotation of 3D panels according to that of the site manager.

➫ Recovery and treatment of the model:

PCMO: Construction Site Software, Methods and Organization, is a software for site preparation. In particular, Site Installation Plans and building phasing can be carried out with integration of formwork methods.

From Revit to PCMO: First of all, the model we have is in .rvt format of the Revit software. To be able to open it in PCMO, it must be exported in IFC format, an exchange format between the BIM software.

Treatment of the model: Once in PCMO, we had to rework the model. Thus, it was necessary (re) indicate to the software, the dimensions of the sails, beams and poles. Also, we checked that the beams, columns and floors of the R + 2 were well designed and appeared at this level.

➫ Phasing of the model:

From the phasing of the site manager, it was necessary to phase the model. That is to say which veils (walls) are made on Day 1, Day 2 etc ... The rotation takes place in 7 phases, ie 7 days:

➫ Formwork’s rotation:

Once the phasage of the model realized, one can realize the formwork’s rotation. A formwork is a vertical formwork element for making the walls (walls) concrete. There are several sizes of formwork. To carry out a rotation of formworks, it is thus to indicate which boards one uses this day and in which place.

➫ The interest of 3D:

3D allows to visualize errors that would not be seen in 2D, for example feet of formworks that would interfere.

In addition 3D is much more understanding by all, as well the workers, by the customers while passing by the chief of building site

➫ Notes:

Formwork rotation could also be performed for the floors, such as a shoring plan.

It is possible to perform a formwork rotation of vertical elements (sails) and horizontal (floors) on Revit but we do not have a library of formwork elements such as formworks or shoring towers.
