Value engineering is a combination of technical and economic subjects. It is committed to the lowest life cycle cost and reliable completion of the functions required by the client. Value Engineering is an intensive, interdisciplinary problem-solving technique that focuses on improving the value of the required functions to accomplish the goals. It is essentially a process that uses function analysis, teamwork and creativity to enhance value. The International Code Council (ICC) has approved 17 changes to the 2021 editions of the International Building Code (IBC) and International Fire Code, allowing mass timber buildings up to 18 stories. With the addition of three new mass timber construction types (Type IV-A, IV-B, and IV-C). These new types are based on the previous Heavy Timber construction type (renamed Type IV-HT) but with additional fire-resistance ratings. This is the first time in the modern building code history that significantly new construction types have been added (AWC, 2021). This undergraduate research's main objective is to develop a structural design and analysis of an 18-story timber building considering a rational performance-based design approach such as sustainability, environmentally friendly, economy, fire and safety testing, and constructability. The structural systems of the study building are composed of Cross Laminated Timber (CLT) shear walls, CLT floors, glulam columns, and reinforced-concrete link cores. Numerical simulations, such as 3-D finite element model development and non-linear time history analysis, have been used in the design analysis. The application of value engineering to structural design in various design phases has been applied. Further, an analysis of these performance indicators and suggestions of design alternatives have been considered during the value engineering workshops. Finally, the workshop results will be taken into consideration in the design.
