Okay, let’s tackle this. So William Langton has 46 years of experience in construction, which is a long time. He’s a contractor and owner of his own company, which suggests he’s self-employed. Location is Waltham, MA, which is a relatively affluent area. Construction professionals with his level of experience and in this location might charge lower rates compared to urban areas or those with more specialized skills. I’ll use the median hourly rate for construction managers in the US, which is around $40–$75 per hour. Considering his experience and location, I’ll estimate his rate to be around $75 per hour.
