Structural Detail

I seek a structural engineer to expertly design drawings and calculations for a domestic extension eliminating two load-bearing pillars. The project entails devising a structural solution to remove the pillars upholding exterior walls on the first floor per preliminary drawings, yielding an unobstructed open floor plan with the structural support situated discreetly above the ceiling. The optimal design should specify load redistribution through inserted steel beams to safely substitute the pillars whilst adhering to construction codes. Proficiency in residential structural analysis and technical illustration of engineered solutions is required to skillfully resolve this architectural challenge.
