The stadium seating design concept
revolutionized the cinema experience by providing patrons with unobstructed viewing sight
lines. The new requirements meant taking the exiting sloped floor prototype design
concept and modifying it to incorporate the new stadium seating elements that satisfied
building codes and operational concerns.
Having developed the LCE sloped floor prototype, the
architect and engineering firm of Fishbeck, Thompson, Carr and Huber (FTC&H) embarked
on creating a new functional design.

Several important challenges immerged as a
result of the new concept, (1) an increase in cost, (2) loss of floor plan efficiency, (3)
accessibility, and (5) construction time. The increase in cost is primarily
attributed to the increase in building height and footprint dimensions. In turn all
the building systems were impacted as well. To address part of the increase in cost
concern, several stadium framing alternatives where investigated, among them:
Each alternative offered advantages
and disadvantages. The impact on construction phasing, ease of construction and
speed, became the focus in evaluating and eventually selecting the best system to
meet the project requirements.
- Cast-in-place concrete stadium risers over
- Precast stadium platform and risers on masonry
- Metal stud framing stadium risers, with
metal deck and concrete platform
- Structural steel framing, with metal deck and concrete
The modular nature of a multiplex
theatre building, lends itself to sequential linear scheduling. Enclosing the
building and completing all overhead work in each auditorium is a primary focus in theatre
construction. The introduction of stadium seating dictated a re-evaluation of that
work sequence. Scheduling consideration narrowed the alternatives to two: metal stud
and structural steel framing system.
Both systems met the cost and work
sequencing criteria. The structural steel framing system was adopted for the new
prototype structural frame system and the metal stud solution was selected for use in
stadium conversion of existing slope floor auditorium projects.
In today's business environment, the
long term success of many projects may depend on being open for business on a specific
date for competitive reasons. Therefore, tight cost and scheduling controls,
innovative designs and team cooperation are essential elements for project success.
