Structural Engineering is a highly specialized field within the broader scope of Civil Engineering. It deals with physical objects or systems whose main function is to resist loads or dissipate energy. The practice of Structural Engineering can involve designing or supervising construction; or enlarging or altering structures or portions of structures. The purpose of Structural Engineering is to determine safe design and construction proven by mathematical calculations based upon scientific principles and engineering data that determine size and strength of parts based on loads and stresses.

Forensic Engineering seeks to locate causality in the case of materials, products, or structures that fail or do not function as intended, resulting in personal injury or damage to property. Webster's Dictionary defines forensic as "relating to or dealing with the application of scientific knowledge to legal problems." Forensic data is most frequently used in civil law cases. However, insurance companies regularly use forensic engineering reports to understand and resolve property and casualty loss claims.

An Expert Witness is one who has specialized education, training, skills, or experience such that their official testimony regarding evidence within the realm of their expertise may be relied upon by others in determining a judgment in a court of law. Expert Witnesses are expected to have scientific or technical knowledge beyond that of the average layperson, yet have the ability to communicate this knowledge in a way that is understandable to the general public.

Risk Management involves reviewing structures and operations of an organization to identify and reduce or eliminate potential threats to the organization. This results in reduced liability and lower insurance rates for the organization. With the recent increase in employee and consumer related litigation, Risk Management is especially important in today's corporate environment.

A due diligence report is a study of a business or product conducted by a third party with experience in the industry of that business. In the case of forensic engineering, an expert in the industry of the business or product works under the supervision of the licensed professional engineer and prepares the report upon which the engineer's final due diligence report is based. The final report includes, but is not limited to the name of the party requesting the investigation, the name and credentials of the person(s) performing the investigation, steps taken to conduct the investigation, lists and photos (when applicable) of all locations and items relevant to the investigation, as well as a detailed report of the investigator's findings.

Value Engineering is used in government, construction, defense, and transportation industries. It involves an analysis of the functions of a structure, product, or system performed by qualified personnel with the aim of improving performance, reliability, quality, safety, and life cycle costs. Essentially, Value Engineering seeks to reduce cost while preserving or improving function. Practically, Value Engineering works to identify and eliminate unnecessary expenditures.

Site Surveys include detailed inspection, field measurements, research and data analysis to plan, design, and establish boundaries. They can also involve mapping, construction layout, and precision measurements of length, angle elevation, area, and volume, as well as horizontal and vertical control surveys.

A Feasibility Study systematically determines and documents the viability of a project. Feasibility Studies help a company to avoid wasting precious time and resources on projects that are unlikely to be successful. A Feasibility Study can also be used as the basis for a business plan, offering potential investors evidence that a proposed project will indeed be viable, resulting in a probable return on their investment. Feasibility Studies ultimately decrease field research time and reduce waste by weeding out projects which are not fiscally prudent.
