92 • JuLY 2014 FINAL FORM CONCRETE MASONRY A new Knight Transportation site in North Las Vegas, Nev., earned kudos from the Concrete Masonry Associa- tion of California and Nevada, which showcased the project in its Profiles in Architecture newsletter earlier this year, and the Cemex employees who produced its concrete masonry units. Cemex Operations Manager-Ma- sonry, Nevada Division-Pacifc Region Chris Hill took his staff on a feld trip to the major feet operator's newest satellite business offce and driver lounge. The building is the frst in a series, a second one planned to house feet fueling, truck repair, parts stor- age and dispatch offce. A New York Stock Exchange-traded company, Knight Transportation runs 4,000- plus tractors and 8,800-plus trailers nationally, and has been named to the Forbes Magazine Top 200 Best Small Companies 15 years in a row. Cemex landed the offce and driv- er lounge contract because it was able to satisfy the architect's call for units with three split faces and a honed face. The latter type had to be created with cured, split units, plant crews sawing off split corners and facing them with a honed segment— yielding a custom 8- x 8- x 16-in. product. The units were molded on a Besser Ultrapac four-at-a-time ma- chine, which at the Cemex Nevada line runs alongside another Ultrapac and a V3-12 Vibrapac machine. On the heels of the Knight Transportation project and its unique unit-fn- ishing requirements, Besser representatives conducted a fve-day course for Cemex Nevada and other Pacifc Region site staff. Hands-on, interactive ses- sions between a classroom and the Nevada Ultrapac production line covered machine setup, proper adjustments, maintenance, electrical troubleshooting and mold changes. SPLIT DECISION Honed and split face concrete masonry units contrast with natural sandstone and stucco accents. Steel trellis treat- ments shade the west and south elevations to reduce inte- rior heat gain and sun glare. The offce and driver lounge building will be followed by second and third phases bringing the North Las Vegas site a fve-bay maintenance garage and additional offce space. Phase one project principals are Aptus Group, architect; Halcrow/CH2M Hill, engineer; R&O Construction, general contractor; Diamond Masonry, subcontractor. PHOTOS: Aptus Group
