Agree with sentiments in many of above posts. It is not at all easy to make a living as a consulting structural engineer. Most of my office’s clients are Architects and they typically request not-to-exceed proposals on a project-by-project basis. When something happens during the project that requires more of the Engineer’s time, that kind of agreement puts the onus on the Engineer to convince the Architect (and indirectly, the Owner) to pay more. Its usually an uphill battle from the start, since even getting paid on time for the base Scope of Work can be difficult.
Have heard several Engineers that have been practicing since the 50's comment that there has been a distinct, continuing downturn in the respect accorded the profession, and in particular how structural engineers are treated in a sub-consultant relationship. Is this somebody's fault? I don't know. I began working as an engineer in the late '80s, so from my perspective there has not been that big a change- just "more of the same old same old".
It would be great to work for an hourly rate on all projects and not have to bid or propose, but the reality is that none of our clients would hire us if that is all we offered. Some of you may be thinking that we should get better clients. Agreed. Easier said than done though. Anyway, that type of client if not extinct is definitely on the Endangered Species list.
Some of our clients shop around for a lower price on each project. My office, which is pretty efficient and has a relative low overhead, more than once has been grossly underbid by big firms who need to keep their large staffs busy. Sometime I think Architects ask for a bid from us just so they can use it to beat down the price of a consultant they really want to use.
On the other hand, my office has also been guilty of knowingly proposing a lower bid just to get a project, particularly as one poster said, when trying to get a foot in the door with a new client. Its very tempting to do.
Here's what I propose to remedy this. Its not the clients that is the problem, really. Engineers must appreciate their own value and skills. They must more consistently require fair compensation from clients while continuing to hone their efficiency and knowledge. Whyun's advice seems best. Figure out want you need to charge to cover your costs and make a living, and stick to it.
Whenever you are tempted to undervalue your services, either by charging too little, not speaking up when the Scope changes etc., remind yourself why you are an Engineer. For me it is the sense of accomplishment when a thorough, complete set of drawings goes out the door, and as I see the structure go up in the field. For others it might be the opportunity to work in one of the professions, compensation, enjoyment in using mathematics, problem solving etc etc.
Now remind yourself that in the long run, you will not be able to continue doing this work you enjoy if you undercharge. If you do try to stay in the field and undercharge, you will end up either doing poor quality work (The heck with that!) or going out of business.
Enough said. God bless all structural engineers.
