Telescopic Seating Systems Product Warranty 1-Year Guarantee: The entire installation will be guaranteed against faulty materials and workmanship for a period of one year. This guarantee excludes any parts determined to have been subject to accident, alteration, abuse, misuse, or neglect. 3 ITT.HT.02.10

Telescopic Seating System Types: Wall-Attached (Forward Fold) The economical wall attached system is the most typical application of telescopic seating in which the bleachers open in the forward direction. They may be specified with either manual or power operation. The units mount directly to a wall and/or to the floor. Rear cut-outs or truncations may be necessary to accommodate column projections and other obstructions. (For installations over 24 rows, consult factory) Standard sections offer best economy. Individual sections make up banks of seating. For costefficiency, use standard section lengths and minimize the number of sections in each bank. For example, an 100 bank of seating may consist of four (4) 25 sections. Code compliance and all load testing data is based on the longest possible section lengths. Truncations/Notchouts: These are cut-outs of one or more rows to create space for wheelchair access or to allow for obstructions (columns, portable backstops, etc.) Please see ADA Planning page in this section Overhead obstructions: Items such as side court backstops, lighting, building truss and duct work should be out of reach of spectators when they are standing on the bleachers. This will eliminate potentially hazardous conditions and provide an unobstructed view for the spectator. Operating clearance: A distance of 2-1/2 from the end of the bleacher (including rails) to the wall or obstructions is recommended. Wall requirements: Ideally, the walls to which the seating will be attached will not have column projections or other obstructions greater than 1-1/2. When columns extend further than 1-1/2 into the room, it is recommended that the seating be cut-out around the column rather than installing in front of the column and filling the space to the wall or employing back rails. Both of the methods are more expensive and require more space than the cut-outs. Floors: Floors should be able to withstand a concentrated point load, per square inch that varies by the system size and quantity of structural sections. Synthetic floor surfaces should be static load tested to determine suitability. Wood floors should be solid blocked under bleacher supports. 4 ITT.HT.02.10

Telescopic Seating System Types: Free-Standing (Floor Attached) Free-standing systems are similar to wall-attached units, however, they are permanently attached to the floor only. These are typically used in applications where bleachers are required to be located away from walls or when wall construction prohibits attachment. Free-standing system guidelines: 20 rows at 10-1/4 rise, 17 rows at 11-1/2 rise, 12 rows at 16 rise. Please contact the factory for applications requiring higher rows. NOTE: Larger stack dimensions may be required. Back panels and rails: When Free-Standing units are located away from a wall, back panels are suggested and rails are required for safety purposes. Back rails are required for spectator safety. All Interkal back rails contain vertical intermediate members to eliminate the ladder effect. When the units are open or closed, back panels discourage access to the understructure and improve aesthetics with a flat wall surface. Standard back panels are provided 8 high. Floor: Flooring must be suitable to anchor the rear row(s) vertical posts. 5 ITT.HT.02.10

Telescopic Seating System Types: Reverse Fold Reverse-fold systems are typically used in balcony applications to recover floor space for multi-purpose activity areas. The first row is fixed and the entire unit moves in a reverse direction until fully extended. Forward travel (aisle recovery): An aisle recovery system (optional) can be provided that will create a front aisle space when the seating is open and close over the aisle when the seating is in the stacked position. Not available with truncations. 42 max. Longer forward travel will increase stack size. rise: Proper row rise is important to achieve an adequate sight line. 11-1/2 or 16 rise is recommended for optimal sight lines. Less than 11-1/2 rise does not provide wide scope vision of main floor activities. Back panels: Suggested on reverse-fold units, back panels discourage access to the understructure and provide a flat wall surface when seating is in the open or closed position. Standard back panels are provided 8 high. Back rails: Since reverse-fold systems are generally located away from a permanent wall, back rails are required for spectator safety. All Interkal back rails contain vertical intermediate members to eliminate the ladder effect. Overhead obstructions: Be sure to provide for adequate clearance of overhead obstructions. Verify minimum applicable building code clearance required above the last deck or last row seat. 6 ITT.HT.02.10

Telescopic Seating System Types: Recessed For seating units in a recess generally under a balcony overhang. Typically a recess is created by extending the balcony over the main floor and using this space as storage for the retracted telescopic units. The purpose is to achieve more balcony seating and more usable main-floor space when the system is fully retracted. Understructure: A recessed system utilizes extra rows of understructure linkage or scissor mechanisms in order for the bleacher to stack under the balcony. NOTE: Recessed system stack dimensions are larger than Wall-Attached systems. Recess opening: The clearance between the top of the last row seat and the under side of the recess is recommended to be approximately 3 to 4, but can be as small as 1-1/2. Balcony access: Since the recessed units can serve as access to the balcony seating, it is necessary to coordinate the balcony height with the height of the last row of seating. Recent building code changes allow for all step heights to vary as you transition to adjoining construction if properly marked with contrasting step colors. These tolerances may be unachievable and code variances may be required. Please see Balcony Access Chart in the Design Guide/Codes section. Consult Factory for design assistance. 7 ITT.HT.02.10

Telescopic Seating System Types: Mobile Units (Portable) Mobile seating units may be moved from location to location on the same floor level. These are independent, self-supporting units that do not require anchorage to either wall or floor. Typically used in the gymnasium, music room, cafeteria and classrooms, they provide the ultimate in flexibility along with easy manual operation. Choose 10-1/4 or 11-1/2 row rise and 22, 24, 26, 30, 32 or 33 back to back seat spacing. Hydraulic trucks: Required to move mobile units, hydraulic trucks can be either free-standing or selfcontained. Free-standing trucks are recommended for cost-savings whenever two or more sections of mobile seating are required. Self-contained mobile trucks are not recommended on higher rows. limitation: On wood or concrete floors, a maximum of 12 rows with an 11-1/2 rise, or 14 rows with a 10-1/4 rise is recommended (9 to 11 rows on synthetic floors) for convenient handling. With proper planning the desired seating capacity can be achieved without oversize mobile units that can be difficult to handle. Back panels / back rails: Back rails are required, Back panels (standard 8 high) are required on mobile units above 8 rows for safety purposes and not required on units less than 8 rows. Back rails are required for spectator safety. All Interkal backrails contain vertical intermediate members to eliminate the Ladder effect. When the units are open or closed, back panels provide a flat wall surface and discourage access to the understructure. 8 ITT.HT.02.10

Vari- is a flexible system which can be provided in wider sizes than standard notchouts. The width is governed by the understructure layout. Recoverable Truncation. A recoverable truncation allows flexibility with layout options. Special engineering is required for power operation. Step assemblies will be required if aisles fall in truncations. Front Rails are available as an option for one row deep and required for two row deep. 10 ITT.HT.02.10

Typical Details: Sections Round building Rectangular building Tapered Sections. Used in radius corner applications, a tapered section is essentially a standard section with angled ends. This may be used with Wall-Attached, Free-Standing, Recessed or Mobile Units. (With free-standing trucks only). While this option adds cost and complexity to the project, use of tapered sections provide optimum sight lines and can produce a dramatic arena look to the installation. General Guidelines/Limitations: Even row alignment requires equal angles between sections. Maximum angle is 22.5 degrees. First row width is required to be a minimum of 5-0, or 1/2 the width of the last row, whichever is greater. Operating Clearance Between Sections. On manually operated banks, space is required between sections to assure adequate operating clearance. This helps eliminate binding and damage to the system if sections are not opened in straight alignment. Operating Clearance To Wall. Space is required between the end of sections or rails and any wall or obstruction. In case sections are not opened in straight alignment, this helps eliminate binding and damage to the system. The space required varies by number of rows and type of operation. 11 ITT.HT.02.10

Typical Details: Definitions Section: The deck assembly, seating options and understructure are the three major components that make up a section. Standard section widths vary from up to 26 depending on number of rows and the bleacher type. Bank: A bank is comprised of a number of sections grouped to function as one, not necessarily tied together. Bank lengths can vary up to 16 feet to hundreds of feet. / Tier: With chair seating, each full deck (tier) counts as a row. In bench seating, each row of modules counts as a row. These diagrams each illustrate 3 rows of seating. 12 ITT.HT.02.10

Typical Details: Understructure SuperSlide TM This low friction flexible rod system assures positive engagement of vertical supports without binding for smooth operation over uneven floor conditions. It maintains proper vertical column spacing, reduces wear and helps eliminate racking damage. Locks Stabilize the bleacher under load in the extended position by securely locking each support post to an adjacent post. They automatically engage and release for opening and closing operation. Individual row locks make it possible to open any number of rows without opening the entire bank of bleachers. Through-bolt fastening used at all frame, brace and deck locations. SAE-grade 5 or 8 bolts with lock washers and hex nuts provide friction resistance. Deck Supports (also referred to as combo brackets ) help prevent sagging and potential binding during operation. Sway Braces: Sway braces fabricated from steel are essential for bleachers to resist the compression and tension forces created when the bleachers are loaded. The overall number of the sway braces are determined by 2 per row, per section. 18 ITT.HT.02.10

Dimensions: Field Check Checklist Following are some guidelines, critical information, needed to make the engineering process go smoother. Taking the time to verify this information can improve cost-efficiency, processing and installation time for the project. Obstructions: look for and dimensionally locate any: Doors/Windows Pipes/Duct work Drinking fountains Columns Electrical boxes/conduit X-Bracing Floor/Wall vents Divider walls/curtains Fire extinguishers Switches/Outlets Overhead clearances (backboards, light fixtures, acoustic panels, etc ) Wall Information: Is it load bearing? Verify with proper officials that bleachers can be attached to it. Concrete block filled or hollow Solid concrete/ Brick Stud wall wood or steel We need the stud spacing and material over top. Steel or pre-fab building If wall is more than one type we need the height at transition. Floor Information: Is it a finished floor? Is existing floor level? Wood Synthetic Verify type/name. Concrete Tile or Carpet Verify what is under it. If floor has a transition, verify the different surfaces and dimensions. Recess/Balcony Access information: Verify depth and height of recess area, measuring in several places for variations. Obtain lowest and highest measurement between finished floor and underside of the recess. Pipes or other obstructions in recess area Balcony height from main finished floor to balcony finished floor. Thickness and material of balcony face Gate locations and sizes Balcony Rails How they are mounted and dimensions of them Mobile Unit information: Dimensions will be larger than charts due to dollies and rails Determine the storage area. Determine that the door width and height will be sufficient Determine the floor conditions that it is to travel over General information: Bank length should not include rail, available space will include rail Make some notation to all specifies or verifies, even if n/a is the necessary response. If information is to be faxed, please be sure that everything is easily legible and follow up by mailing a full sized copy. Pictures are very helpful 44 ITT.HT.02.10

Typical Details: Court Diagrams Basketball Court Specifications 1. If possible, building plans should provide for a court with ideal measurements as stated in Rule 1-1, ample outof-bounds area and necessary seating space. A long court permits use of two crosswise courts for practice and informal games. 2. The ceiling should be at least 25 feet or higher if possible. 3. Instead of the 2-inch minimum boundaries, it is legal to use contrasting colored floor areas by painting the outof-bounds area, the center circle, and the restricted parts of the free-throw lanes so that the mathematical line between the two colors is the boundary. If such contrasting colored out-of-bounds belt is used, it should be at least 8 inches wide. 4. It is recommended that a belt 8 inches wide or more in width be used to mark the boundaries on all courts which have at least 10 feet of open space between the boundary lines and the seating. This plan is urged for all new construction and for other similar courts when the boundaries are remarked. 5. It is recommended that there be a 2-inch wide broken line consisting of 12-inch segments, 12-inches apart, of a color different from that of the boundary, at a minimum of 6 feet outside the court extending from sideline to sideline and parallel to the end line. 6. Optional coaching box tableside. Bounded by a line 28 feet from end line, the sideline, a line 22 feet from end line, and the team bench. Located off the court, 2 inches wide and color contrasting with boundary line. NOTE: State associations may, on an individual basis, allow alternate bench locations. 7. The court should be uniformly and adequately lighted. Lighting engineers should be placed in charge of this important factor when planning new installations. For information on recommended specifications for lighting, you may contact: Illuminating Engineering Society of North America, 120 Wall Street, 17th Floor, New York, New York 10005, Telephone (212) 248-5000. 60
