An in-house BIM Manager is one of the most important and valuable business decisions one can make at any stage of a company's Revit adoption/implementation period. They are specialists in their fields, have expert knowledge of a wide range of software solutions, and most of all, vast industry experience.
It so often happens that a company provides the BIM Manager role to one of their staff members, assuming that their company will now instantly experience an increase in performance, have less coordination issues, and meet unrealistic deadlines. Unfortunately, companies often expect the staff-based BIM Manager to also actively work on a project.
There are 24 hours in a day. In our industry, we need at least 6 hours of sleep. At least an hour or two of rest. Two hours of travelling to and from work. This leaves the average staff member with 14 theoretical hours in which to be productive. Studies (and common sense) have shown that a 9 hour working day is "optimal" for the average worker.
Will it really be productive and realistic to expect one staff member to fit two job descriptions into a 9 hour day (or 14 hours some)?
The benefit of contracting a BIM Manager to be part of your team is that they do not get pulled into projects. Yes, a big part of their responsibilities are to coordinate all drawings etc., but they typically do not assist with designing a building, nor do the typical "CAD Monkey" work. Another huge benefit is that they are impartial to office politics (Every office has office politics). Thus they can focus on what they do best: Managing your projects, ensuring that best practices are applied, and coordinating hundreds of drawings, to name but a few.
The responsibilities of a BIM Manager does not end with the few points I have listed above.
