About

RIJA
RIJA was originally established in 1975 as Ray I. Juachon & Associates. Since its inception, the firm has been providing engineering and consulting services to commercial, institutional, and private sectors throughout the San Francisco Bay Area.
RIJA's focus is to provide top tier Engineering and Consulting services to their clients. We consider client requirements, understand project constraints, and deliver high performing - healthy buildings.
Integrated Project Design and Delivery is at the heart of the firms philosophy. We believe client Project Requirements are the foundation which informs Design, Cost, and Constructability; and in todays fast paced environment of construction, it is imperative to establish a cyclical relationship between these three factors to provide the most value to the project. The firm thrives on the interactive design process and collaboration within the design team and contractors. The company was founded on sound engineering principals and strives to contribute to innovative, cost effective solutions for the built environment.
RIJA has experience in all project types, including multi-family, hi-rise, critical facilities, hi-performance buildings, civic, corporate, healthcare, higher-education, and K-12 schools. We provide power, lighting, and low-voltage design services to many local architects and developers as well as direct-to-client consulting services.
