There are several critical reasons why experienced structural engineers are essential for building design:
Safety and Life Protection
Structural engineers ensure buildings can safely support their own weight, occupants, furniture, equipment, and withstand external forces like wind, earthquakes, and snow loads. Mistakes in structural design can lead to catastrophic failures, collapses, and loss of life. Experience helps engineers anticipate potential failure modes that less experienced professionals might miss.
Complex Load Calculations
Buildings experience multiple types of loads simultaneously - dead loads (the building's weight), live loads (occupants and contents), environmental loads (wind, seismic, snow), and dynamic loads. Experienced engineers understand how these interact and can accurately calculate the combined effects, which isn't always straightforward.
Material Behavior and Selection
Different materials (concrete, steel, timber, masonry) behave differently under stress. Experienced engineers understand real-world material performance, including factors like creep, fatigue, corrosion, and thermal expansion that go beyond textbook knowledge.
Code Compliance and Jurisdiction Knowledge
Building codes are complex and vary by location. Experienced engineers know how to interpret and apply codes correctly, understand which edition applies, and can navigate jurisdictional requirements efficiently.
Problem-Solving and Value Engineering
Experience brings the ability to develop creative, cost-effective solutions. Seasoned engineers can often design more economical structures by knowing where savings are possible without compromising safety, whereas inexperienced designers might over-engineer (wasting money) or under-engineer (creating hazards).
Construction Feasibility
Experienced engineers understand what can actually be built in the field. They design with construction methods in mind, avoiding details that look good on paper but are impractical or impossible to construct properly.
Risk Assessment
With experience comes better judgment about where to be conservative and where flexibility is acceptable, how to handle unusual conditions, and when to seek specialist input.

Foundations can appropriately be described as a necessary evil. If a building is to be constructed on an outcrop of sound rock, no foundation is required. Hence, in contrast to the building itself which satisfies specific needs, appeals to the aesthetic sense, and fills its matters with pride, the foundations merely serve as a remedy for the deficiencies of whatever whimsical nature has provided for the support of the structure at the site which has been selected. On account of the fact that there is no glory attached to the foundations, and that the sources of success or failures are hidden deep in the ground, building foundations have always been treated as step children; and their acts of revenge for the lack of attention can be very embarrassing.-Karl von Terzaghi
