One of the Best in Fire Sprinkler Design Services

Un-Leaded Design Inc., ULD, is a premier fire sprinkler design services firm providing high-quality integrative design to local, national, and international markets. Owner & Founder Ronnie Fujikawa NICET Level IV is a third-generation fire sprinkler designer. He grew up in the shop, following in his father and grandfather’s design steps, learning the integrative skill of design by hands-on experience. From the age of thirteen on he spent his summers working in the fabrication shop. At sixteen, he added a draft table to his bedroom decor. Never one to let an opportunity to learn to pass by, he watched closely as his mother and father designed with a pencil in one hand, eraser in the other. Hands covered in “lead” learning the precise skill of accurate fire sprinkler design.

At Eighteen, he started an apprenticeship program called FAST, and by twenty-one, he became a licensed Journeyman. He spent his twenties fitting fire sprinkler pipe in the field, hands-on, wrench in one hand, pipe in the other. His experience in all areas from the draft table, to the fabrication, to the installation perfectly positioned him for his greatest endeavor- putting down the pencil, pipe, and wrench and moving into the next generation of fire sprinkler design services – the “Un-Leaded Design”. He completed two years of night classes to learn “Computer-Aided Design” or CAD and Un-Leaded Design Inc. was born.
