Careers Building, Lansing Community College (LCC)
Originally designed as a 3-story
building, with a fourth floor expansion planned in the future, this modern
structure had a price tag of $2.7 million. Partnering with the fabricator/erector
to deliver the steel structure of the building, Ruby+Associates applied
value engineering principals and completely redesigned the structural
steel component of the building. This redesign saved enough money to enable
LCC to construct the fourth floor and still bring the project in several
hundred thousand dollars under budget.

The
Ruby redesign eliminated over 700 members, beams and braces, as well as
11,000 shear studs from the floor system, eliminated cantilever perimeter
framing, substituted steel columns for concrete-filled columns and moved
to a completely field bolted structure. The resulting floor system (including
a thicker slab) added minimal dead load to the structure, but increased
the strength of the composite floor system. This redesigned structure
was easier to build, stiffer and much more efficient – the number
of floor beams were reduced by 78 percent and over 300 tons of structural
steel were eliminated! Based on AISC calculations, this amounts to a savings
of over 280 tons of CO2.
