Civil Engineer Needed for Roof Structure Design

Job ID: 38917349

Budget: $30 – $250 USD

Please see the attached project of the columns and beams of the single story building.

Columns are 25 x 40 cm. Beams are also 25 x 40 cm in dimension.

I want to build a two-slope roof with 33 degree angle. Slopes will be on the short sides of the building.

I'm going to use steel box profiles to build the structure and weld them together.

The sheeting will be 13mm OSB. Then 4 cm thick XPS boards and then concrete tiles to finish.

There are no inner walls in the building. The steel profiles will be placed on top of the outer beams.

I want to use scissor truss style but this can be changed by suggestion.

I need a civil engineer to calculate what kind of structure and what dimensions and thickness box profiles should be used. I also need a drawing of how the roof structure should be.
