Allied Builders System

1717 Akahi Street, Honolulu, HI 96819

Allied Builders System is a firm that has been consistently recognized as one of Hawaii’s top 250 companies as well as a top 20 construction company in the state. Its establishment in 1970 has contributed to this recognition, creating long-lasting relationships with owners, developers, designers, architects, and other stakeholders. Over the years, Allied Builders System has built projects for the hospitality, healthcare, education, retail, specialty, and light industrial sectors.

The firm has also been featured in the 2019 issue of Hawaii Business Magazine. 

ICC Group

1001 Bishop Street, Suite #2925, Honolulu, HI 96813

ICC Group is a familiar name in the brewing industry. In 1986, four electrical engineers from St. Louis’s Anheuser-Busch Brewery established the firm. Since then, ICC Group has become the go-to contractor for the brewing and distilling industry. Over the years, it has extended its work to other markets including the hemp and CBD, food and beverage, pharmaceutical, chemical, and petrochemicals industries. It’s also taken a place in the health, beauty, and consumer manufacturing markets. In its primary market—breweries—its most notable work was complete for Saranac, an installation of a new Carbon dioxide recovery system. This system also allows for the reuse of gas for carbonation and packaging. Since this system generates 100% of Saranac’s carbon dioxide, there is no longer a need to purchase and transport from outside suppliers. Doing so reduced cost and the firm’s environmental footprint. ICC Group completed more projects for other well-known names including Coca-Cola, Carlsberg, Pfizer, Heineken, and Novo Nordisk. All these projects have turned the firm into a powerhouse for strategic engineering and manufacturing.
