The market for large architectural and engineering firms is healthy, with a few exceptions. The buildings market for architects and engineers continues to grow at a measured pace, and the passage of the federal Fixing America’s Surface Transportation (FAST) Act, as well as progress in Congress on other federal infrastructure funding initiatives, have many engineering firms in the infrastructure markets optimistic. While low oil prices have depressed the markets for big-ticket oil and gas work and the power market seems sluggish, most U.S. architectural and engineering firms are in a good frame of mind.

However, there is concern about the future. The U.S. economy is not robust, and there are concerns about what impact the outcome of the presidential election will have on regulations and the market. Also, economic and political turmoil abroad could have a significant impact on the domestic market. And within the architectural and engineering professions, there are trends that have many firms concerned about their role in the construction process.
