Construction and
Expansion Joints
The size and placement of Construction and Expansion Joints are critical components to the design and cost of a
seating installation. The following descriptions of these joints are taken from The Architectural Graphics Standard.
Expansion (Isolation) Joints:
These allow movement between the concrete slab and
xed parts of the building such as columns or walls.
Construction Joints:
These joints provide stopping places during the oor
construction. These elements must be taken into
consideration in order to have a successful seating
layout. Each of these joints has a signicant impact on
the particular cost and design for installation.
Horizontal Construction Joints:
These joints are in the concrete riser and are a concern
with riser mount chairs. The concrete is usually pre-cast
(but not always). The location of the joint or the height
of the riser from the deck to the joint are the critical
dimensions. When working on a job with this type of
joint, the riser height and the location of rebar have cost
implications. Special anchors may be required.
(Note: Our cast iron riser mount standards come in
3 sizes to accommodate a low, mid and high rise
situation. Due to cost of materials, the low rise standard
is the most expensive and thehigh rise standard is theleast expensive.) Details of this joint are critical at time
of pricing!
Hussey Seating uses an oset plate to anchor the chairs
without altering the seating plan. The oset plate osets
the anchors enough to clear the joint. There is the
possibility that if one chair is oset, all chairs in that row
may be oset.
Vertical Construction Joints:
There are several options available to accommodate
joints that span a deck of seating.
The most cost eective method is with a carrier plate.Usually only one chair is aected by this anchoring
method. This permits movement of the building without
damaging the chairs.

Products for
ADA Compliance
Hussey Seating Company oers several responses to the requirements for handicap accessibility and seating.
Flip-Up Armrests:
This adaptation is designed to eliminate a barrier for
disabled patrons. The armrest is actually hinged near
the rear to swing up and become parallel with the back.
Each chair with a Flip-Up Armrest is denoted by the
universal handicap symbol for identication purposes.
This option is available on all three plastic chairs
models. It is not available on the Sentinel automate or
semi-automate. A removable armrest is a similar option,
which is available on the (steel) Olympiad.
Armless Chairs:
Some of our chairs do not accommodate the
modications listed here as well as others. To comply
with the requirements of ADA and to meet the needs
of handicap patrons, some chairs are available without
armrests. This option is available on all three plastic
chair models.
Swing Away Companion Chair
This chair is a single, xed chair that rotates 90 degrees
from the ambulatory spectator position to allow for a
patron seated in a wheelchair. Essentially, the xed
chair swings away to provide room for the wheelchair.
There is a lock mechanism, which locks the chair inboth the fore and aft positions. Presently, this option is
not available with the Medallion.

Requirements/Guidelines
General Design Notes:
All oor, slabs and Risers constructed of concrete (pre-cast or poured) must meet the following criteria:
All concrete must have a minimum strength of 3000 P.S.I. or 20,684 N/M Sq. for proper anchor attachment.
All oors constructed of wood must be 1 " (3) thick minimum.
All anchors are supplied by Hussey Seating Company unless otherwise noted. If anchors are to be sup-
plied by someone other that Hussey Seating Company, notication must be made during the submittal
process.
Hardware and Drill Hole Requirements:
The minimum radius of 25 (762) is the primary limitation for a radius project. A smaller radius will require
the use of individual chairs.
ADA - American Disabilities Act:
Maximum length of a sloped oor is 30" (914) after which there must be a level of 5" (152)

Chair Sizing
The chart assists in determining the chair sizes needed in a seating arrangement. The dimension for end spaces
has been factored into these calculations. However, the following chart will provide these dimensions.
Chair Series End Dimension
Fusion 2" (5)
Legend 2" (5)
To use the Chair Size Chart, follow these procedures:
1. Determine the space available for each row. [The chart automatically calculates a 2" (5) spacing at each
end of the row. If you require 3" (8), you must factor the dierence in.]
2. Read down the column marked "feet" and then across the top marked "inches" and nd the appropriate
dimension.
3. Select the chair sizes from the suggested combinations.
4. Staggered seating may be achieved by using varying chair size combinations in alternate rows.
NOTE: Reference applicable building code to determine the maximum number of seats allowed in a row.

Sightline Formula
Principle of Visibility
Line of Clear View for Spectator on Tiered
Seating:
Angle A: Angle of Perfect visibility; looking over allheads.
Angle B: Angle of Good visibility; shifting position to
look between heads on the row immediately in front of
the spectator and over all heads.
Angle C: Angle of Fair visibility; shifting position to
look between the heads of two rows immediately in
front of the spectators and over all other heads.
Denition:
The lower angle of angle C is approximately 5" (13)
above the eyes of the spectators in the third row in
front of the spectators. This angle C is called the angle
of clear view. The tangent of the angle of clear view =
3R-5"[13cm] / 3D, where R is the rise and D is the depth
per row (row spacing).
Head Level from the Floor 4'1" (124)
Eye Level from the Floor 3'8" (112)
Application:
The nal analysis being the perpendicular dimension
from the court line or the line of play to where the angle
of clear view intersects (focal point) should be as smallas possible.

Principle of
Visibility
Angle B is commonly used in determining oor
slope for auditorium, performing arts or theatre type
seating congurations. When angle B prole is used
in conjunction with staggered seating arrangement
(chair staggered or alternated in arrangements of sizes
opposite every other row) it allows unobstructed view
of spectators to a determined focal point at the screenor stage. The nal analysis is to have all sight lines
intersect at the desired focal point.
Angle C is most commonly used in determining riser
or stepped applications for gymnasiums, arena or
stadium type seating congurations. When angle B
prole is used (generally associated with an aligned
seating arrangement) it allows for unobstructed view of
spectators to a determined focal point at court line or
line of play. The nal analysis is to have all the criticalsightlines intersect the focal point or line of play at
generally a maximum elevation of 4' (122).

Dimensions & Calculations
Step 4: Solve for Distance E
Using Trig function: Tangent = Opposite / Adjacent
Tangent of Angle C = Distance E / Distance B
Distance E = Tangent of Angle C x Distance B
Step 2: Solve for Distance A
Using Trig function: Tangent = Opposite/Adjacent
Tangent of Angle C = Distance D / Distance A
Distance A = Distance D / Tan Angle A
Step 3: Solve for Distance B
Distance B = Distance A - Distance
