Okay, let’s tackle this. So Mark Koerner has a strong background in project engineering, with expertise in power generation and energy. He also has skills in Six Sigma, which is a highly valued process improvement tool. Location is Houston, Texas, which is a major hub for the oil and gas industry. Industry standards for project engineers in this field typically range from $100 to $200 per hour. Considering Mark’s skills and experience, I estimate his hourly rate to be around $125, which is slightly below the average for this location and industry, but still reflective of his value proposition.
