Wb Engineers Consultants
Communicator. Client advocate. Business person’s engineer. These aren’t typical descriptions for engineers, but they are all great ways to describe us. Since our first day of business in October and on the hundreds of projects we’ve completed, we help our clients make good business decisions about their systems and spaces. We take complex engineering information and make it easy to understand – so that they in turn can make smart decisions. We started our business during the height of the dot com boom. The internet age set new industry expectations for design projects: schedules were especially tight; a majority of the overall project cost, the MEP engineering and installation had a direct impact on a company’s bottom line; and clients wanted to be informed about the status their project at all times. With an efficient project approach, and having a team that is both great at communication and thoughtful of our client’s business, we thrived in this new business environment. While the dot com boom didn’t last, it shaped the way we do business – even today – in a very successful way. IMPROVING THE WAY THINGS ARE DONE™ We have a talented team of over 150 professionals, well educated in their respective disciplines and many with great credentials behind their names. Beyond that, Improving the Way Things are Done is important to who we are as a company. We are always thinking about ways to use technology more effectively, design more efficiently, and communicate better.
