(SEE) was retained to design three different new
jumbotron scoreboards for the Spartan Stadium. The south scoreboard was approximately 140 feet
wide by 60 feet high and 60 feet above the ground level. The north scoreboard included two 84 feet
wide by 40 feet high boards (50 feet above the ground level) and a 15 feet high by 430 feet
long ribbon screen. The ribbon screen was over the entire north side of the
The south and north megatron scoreboards were designed as a free-standing
structure with deep caisson foundation. On the other hand, the ribbon screen was attached to the
stadium concrete structure. Therefore, the existing concrete structure and foundation needed to be
checked to make sure that they have adequate structural capacity to support the additional
load. SEE analyzed the
scoreboards for lateral directional wind, earthquake, and snow/ice loads by
modeling them in an advanced structural analysis and design
MSU originally requested the columns for the scoreboard structures
to be reinforced concrete to match the stadium structure with independent caisson foundations.
However, after bidding the contractor purposed to build the columns with steel trusses and the
north scoreboards with helical piers as a cost saving measure. MSU accepted the cost
saving substitute and we worked with the contractor to redesign the north scoreboard foundations
and concrete columns.
the designed bid documents for the scoreboards, assisted the MSU with bidding the
project and oversaw the construction.
