Okay, let’s tackle this. So James has a broad range of skills, including construction management, architecture, and sustainable design. He's also worked on mixed-use projects and historic preservation, which are in demand. However, his role is more specialized than a typical construction manager or architect. He's also worked as an expert witness, which can command higher rates. Considering his skills and experience, I'd estimate his hourly rate to be around $125, which is slightly below average for a construction expert with similar qualifications. This is because his role is more niche and he may not have the same level of demand as some other construction professionals.
