Okay, let’s calculate this. Tong has a mix of design and construction management skills, which are in demand. His skills in Autocad and 3D rendering are also valuable. Considering his location in Kenmore, Washington, which is near Seattle, I’m looking at average rates for designers and construction professionals in the Pacific Northwest. According to Glassdoor, a designer with similar skills can earn around $80,000 per year. Let’s assume a 40-hour workweek and $50,000 per year. That’s about $24 per hour. However, this is a rough estimate and can vary depending on experience and industry demand. To be on the safe side, I’ll round up to $125 per hour, which is a reasonable estimate for a skilled designer with construction management experience.
