Residential Beam Calculation

I need precise calculations for a wooden beam, specifically engineered wood like LVL or glulam, intended for a second floor decking on a garage project. The garage footprint is 30'W by 28'D with a 18'W by 10'D workshop. We will have 10" poured concrete rebar reenforced foundation walls. We would like the right-hand bay of the garage to have a second floor with decking to store items. In addition, we will have decking above the workshop. Attached are the current plans from our architect.

Key requirements include:
- Structural integrity and safety
- Compliance with local building codes
- Detailed calculations and supporting documentation

Ideal skills and experience:
- Structural engineering background
- Expertise in wood and engineered wood materials
- Experience with residential building projects
- Proficiency in relevant software for structural analysis
