A HISTORY OF SPECTATOR SEATING

T

he history of stadiums extends from the mythological era when people would gather to witness heroes such as Heracles (or Hercules according to Roman mythology) prove how strong and powerful they were. Even the term stadium – originating from the Greek word “stadion” for a unit of measurement equaling the length of 600 human feet – comes from ancient Greece where Olympia stadiums grew in popularity. It has been said that the first stadium originated in the 8th Century B.C. Stadiums in ancient Greece could welcome up to 45,000 spectators while the Coliseum in Rome, built in the 1st Century A.D., could accommodate over 50,000 spectators.

The earliest stadiums involved stands built in a horseshoe around a field. Romans are credited with building stands into hillsides while others used stone – or even marble – to provide spectators a stair-stepped view on an elevated level; Romans are said to have given stadiums a monumental shift to what we know today starting with amphitheaters used for performances. While the amphitheater provided maximum seating by utilizing seats fully enclosing the field, the circus style of stadium featured seats in a horseshoe configuration with one end open in order to focus on chariot racing. In the 4th century A.D. the church abolished the Olympic Games stating the Games were pagan rites contrary to 3

religious rites, causing many sports buildings to be abandoned.

Following this development and during the Renaissance, running events and equestrian events were reintroduced and held in open spaces fitted with wooden tiers and temporary structures to seat the most important spectators. Stadium design remained largely unchanged for over 1,000 years, although jousting fields generally used a design open at both ends to facilitate access and the egress of horses.

The late 1800’s saw a rise in wooden stand construction, and with the increase of sporting events in America (i.e., horse racing and boxing) and after the Civil War, there was continued growth of wooden high capacity bleachers, mostly at horse racing arenas.

In the early 1900’s, modern stadiums continued to host large amounts of spectators in an age where there was no television. At this stage, stadiums were uncomfortable and facilities only offered basic amenities such as standing areas, small seating stands, and small roofed-areas for key audiences.

The evolution of stadiums and high capacity bleachers developed through the years. In the 1930’s, wood platforms gained popularity especially in football stadiums, however, it is important to note that as early as the first decade of the 1900’s concrete stadiums

began to emerge. In 1903, Harvard Stadium opened, and is now the nation’s oldest permanent concrete structure for college sports. In the 1930’s, the Works Progress Administration built 2,500 high capacity bleachers with a combined seating capacity of 6,000,000. Most were concrete and are still in use today.

By the 1950’s, stadium design was leaning toward more multiuse design with the goal of attracting a variety of event types. A good example is O.co Stadium in Oakland, CA, one of the last remaining venues to host both NFL and MLB teams. With the rise of suburbia in the 1950’s, bleacher seating began to find its way outside the city. During this same decade, steel high capacity bleachers with wood planking were introduced. The 1960’s saw the birth of the first domed stadium, the Astrodome, which created the need for artificial turf, as grass would not grow in the enclosed environment. The first aluminum seat board was also invented, providing a way to replace rotting wood seats on existing high capacity bleachers. With the welcoming of broadcasting and new amenities such as food and beverage, crowds at stadium events started to increase. By the 1970’s, the industry was building permanent I-beam high capacity bleachers with aluminum decking and seats, and the 1990’s witnessed further improvement with the introduction of welded decking systems and interlocking

decking systems that required less maintenance and were a more economical option compared to concrete high capacity bleachers.

By the 2000's, the interlocking deck system was introduced as the new technology for the industry.

Interestingly, until the 1990’s, wood plank stands were still quite common. Unfortunately, several catastrophic fires in wooden stadiums killed hundreds of people, changing the view on spectators’ safety and promoting recommendations to change the materials used. It was concluded that all stadiums needed to be constructed of non-flammable materials. As a result of the new safety regulations, which also specified that stadiums should provide seating for all attendees eliminating “standing only” sections, facilities became more accessible, safe, and comfortable, drawing a more diverse and heterogeneous spectator group. The process of upgrading stadiums gave the opportunity to introduce even more new and improved amenities, such as merchandise sales, museums, boxes, and restaurants.

In the new century, we continue to see improvements like one-piece platforms, beveled thresholds, hardware that doesn’t penetrate through decking, seat upgrades that don’t require changes to the structure, and leading edges on stairs.

A HISTORY OF SPECTATOR SEATING Today, spectator seating comes in all shapes and sizes – from the single bleacher at a local park to large professional sports venues, but they all have one goal in common – to provide a comfortable place to watch a favorite event.

Mitered bleachers feature angled seating sections designed to optimize sightlines and seating capacity. The angled, or "mitered," configuration allows for better viewing experiences and more efficient use of space, making them ideal for sports venues, auditoriums, and other large gatherings. These are most often seen at baseball and softball stadiums and fields.

High Capacity Bleachers, defined as those over 33’ long, provide an efficient and cost-effective solution to the challenge of seating large crowds in stadiums, arenas, and outdoor event spaces.

These bleachers are designed with safety and comfort in mind, featuring sturdy construction and optional enhancements like backrests and contour seats to ensure a secure and enjoyable experience for spectators. Incorporating a press box on one side of the high capacity bleachers is ideal for high school and college football fields. Press boxes offer an unobstructed view for essential game day operations, including media coverage, coaching, commentating, timing, scoreboard controls, and lighting. They provide a convenient workspace for managing teams and deliver numerous benefits to schools and organizations.

Transportable bleachers are the ideal solution for fairgrounds and similar venues that require flexible seating arrangements across multiple areas at different times. These bleachers offer the convenience of mobility, allowing event organizers to quickly and efficiently relocate seating to accommodate various events and

crowd sizes. Designed with durability and ease of transport in mind, transportable bleachers ensure a comfortable and safe experience for spectators. Their versatility makes them perfect for accommodating diverse events, from concerts and shows to sporting events and exhibitions, enhancing the overall functionality of fairgrounds.

3, 4, or 5-row aluminum bleachers are the perfect seating solution for multi-field venues such as soccer complexes. Their compact design provides ample seating while maintaining a low profile, ensuring unobstructed views of the action on multiple fields.

Lightweight and durable, these bleachers are easy to install and reposition as needed, making them ideal for dynamic environments.

Stadiums today can seat between 15,000 to 100,000 people, with some, like the Indianapolis Speedway, accommodating up to 250,000 spectators. They serve as architectural and technological hubs for communities, often designed for multiple sports such as football, soccer, and track. For example, Washington State’s Qwest Field & Event Center hosts not only sports but also job fairs, concerts, trade shows, and more. While traditionally open-air, modern stadiums may feature dome roofs or movable roofs to protect against weather, and smaller venues may use independent shade structures.

No matter the design style, building a spectator venue can be a substantial undertaking in planning, funding, building, and promotion to help the venue generate revenue. Additionally, these spaces have evolved from the simple u-shaped track to more complicated structures with a wide range of facilities. Modern designers take into account the following when planning for a new venue: • Long-term financial viability by designing the stadium as a multipurpose facility • Aesthetics and architectural interest • Reduced energy use • Minimal disturbance to ecology • Environmental sustainability • Retractable roofs to be used in any weather • Security and anti-terrorism measures • Providing an environment that will include individuals of all abilities

Bleachers and grandstands bring people together, build a sense of community, and are a valuable asset to a venue, team, or school.

GRANDSTAND AND BLEACHER APPLICATIONS B

leacher designs vary by location, so it is certainly accurate to say that there are bleacher designs for a variety of locations and/or purposes. From the large structures found at racetracks and major sports stadiums to the small tip and roll models used to cheer on the local little league team, bleachers have taken spectator seating to a new level when it comes to watching a favorite pastime.

Most people can easily recall a favorite memory about a game or event where they cheered along with the people seated around them, united in a common cause. Bleachers bring people together, build a sense of community, and are a valuable asset to a venue, team, or school.

a view of a stage or event is an important part of the gathering.

Bleachers are a great way to create camaraderie among spectators, uniting them in a common event.

Go to any game or event, and it is often as much fun to watch the people in the stands as it is the game itself. They cheer together, shout together, and express dismay as a unit when their team fails to score or is beat. They make huge posters to hold up, they do the “wave,” and other fun activities meant to unite the people seated as a whole. If you have an event where people come to watch, the appeal of bleacher seating as a unifying force cannot be denied.

Beyond these super-facilities are countless schools and universities, gyms, recreation facilities, sport fields, pools, and parks which are also utilizing bleachers, depending upon their needs and available space.

The use of spectator seating is growing in municipalities, which often have the need for transportable bleachers that can be used for parades, public concerts, and pop-up events throughout the community. One myth of spectator seating design is that if a venue cannot afford large permanent structures to augment their facility, there are no affordable options.

From small sporting events to daylong festivals in parks, there is often a need to provide temporary seating that assembles quickly and moves into storage after the event. While many events encourage people to bring folding chairs and blankets for seating, providing a bleacher can offer additional comfort, as well as accommodate more people in a smaller space, especially if having

As this guide will demonstrate, there are a number of both transportable and permanent bleacher options that can seat people for smaller events, and a variety of seat styles and material options to consider as well. The best option is to contact a supplier, discuss your project needs, and let them offer recommendations that will accommodate both your needs and your budget.

Bleacher seating is a common feature at children’s centers, golf courses, and other venues that need to provide "seating with a view" for gatherings.

According to the 2024 State of the Managed Recreation Industry Report, bleachers and seating continue to be a top priority for facility planning. The report indicates that bleachers and seating are among the top 10 planned features, with an increasing number of respondents planning to include them in their facilities.

This trend underscores the significance of spectator seating across various applications beyond the traditional stadium setting. From temporary bleachers for parades and park events to permanent structures for open-air venues and sports gatherings, the demand for spectator seating in public spaces is undeniable.

STANDARDS AND CRITERIA T

o help ensure project success, it is critical to understand and address a variety of federal, state, and local guidelines, as well as considerations for safety and performance. Since state and local recommendations may vary, it is best to check with government agencies in your area to obtain a complete list of applicable codes and standards.

Building Codes and Related Considerations The codes applied to the design for spectator seating are determined by the governing body of that specific location. It could be at the state, county, or city levels. Furthermore, the assembly could be ruled by other types of governing agencies such as a school board that will have jurisdiction. That leading body is responsible for establishing what code (and what edition of that code) will apply in their jurisdiction.

persons with disabilities. Some governing agencies will be specific to how they want to apply this law and will provide plans for review during the approval/permitting process accordingly, while others will rely on the design professionals to incorporate ADA. In either case, each new facility providing assembly seating in the United States should comply with the ADA and its guidelines. The ADA has several items addressing assembly occupancies and what must be provided to accommodate those with disabilities.

For decades, the major regional building codes have been used to evaluate the safety of various building components making up the primary elements of means of egress to include stairways, ramps, small changes of elevation, and level surfaces.

However, the last Standard Building Code (SBC) was published in 1994, the last Uniform Building Code (UBC) was published in 1996, and the last BOCA National Building Code was published in 1997.

In most cases, the latest edition of the International Building Code (IBC) is the primary basis of design. In 2000, the IBC launched a stand-alone subsection of its code in order to clarify issues pertaining specifically to assembly seating in accordance with ASTM guidelines in establishing codes.

That document was first released in 2005 and has been updated in 2007, 2012, 2016, 2019, and most recently 2023. The International Code Council (ICC) works hand in hand with the IBC and in some instances may even be redundant. The ICC 300 highlights the standards for bleachers, folding and telescoping seating, and high capacity bleachers.

Inclusion The Americans with Disabilities Act (ADA) is a federal law that administers how facilities provide access and accommodations to

Make A Stand

While it is not the intent of this resource to identify all of the specific requirements of the ADA, there are four prominent issues relating to the design of grandstands that should be understood: 1) quantity, 2) location, 3) access and, 4) sightlines. For more information, refer to the resources section in the back of this guide.

1. Quantity — The number of wheelchair accessible spaces required are based on the following chart.

2. Location — Number and location of wheelchair spaces must be an integral part of the seating plan so people using wheelchairs are not isolated from their companions.

3. Access — Accessible seating must be on an accessible route that provides access from parking and connects to all public areas.

4. Sightlines — Wheelchair spaces shall provide lines of sight complying with the guidelines. In providing lines of sight, wheelchair spaces shall be dispersed. Wheelchair spaces shall provide spectators with choices of seating locations and viewing angles that are substantially equivalent to, or better than, the

choices of seating locations and viewing angles available to all other spectators so that their experience is substantially equivalent to that of other members of the audience.

Ensuring ADA compliance in spectator seating goes beyond meeting legal requirements; it enhances the overall experience for all attendees. Key considerations include providing multiple wheelchair-accessible spaces, integrating these spaces throughout the venue, and including companion seating to avoid isolation.

Good sightlines for wheelchair users are crucial to ensure an equitable viewing experience. Investing in ADA and inclusive seating not only fulfills legal obligations but also boosts community engagement and venue reputation, potentially increasing attendance and revenue.

ADA Ramp Requirements To ensure accessibility, ramps must comply with both the Americans with Disabilities Act (ADA) and the International Building Code (IBC). According to the ADA, ramps must have a slope not steeper than 1:12, meaning for every inch of height, there must be at least 12 inches of ramp run. The IBC generally aligns with this requirement, mandating a maximum slope of

PH: 888-568-9064 FAX: 260-482-7449 WWW.BLEACHERS.NET

Drawing of Top Down Elevated ADA Unit

1:12 for ramps used for wheelchairs. Ramps should also include landings at the top and bottom with a minimum length of 60 inches to provide maneuvering space. Handrails are required on ramps with a rise greater than 6 inches, and they must meet specific height and clearance guidelines to ensure safety and ease of use. Compliance with these standards ensures that ramps are both functional and safe for all users.

EXCEPTION: Wheelchair spaces in team or player seating areas serving areas of sport activity shall not be required to comply.

Life Safety The National Fire Protection Association (NFPA) has issued the NFPA 102 Standard for Grandstands, Folding and Telescopic Seating, Tents, and Membrane Structures to address life safety concerns for spectator seating in relation to fires, storm, collapse, and crowd behavior.

Life Safety is mainly associated with egress and guard railing, the single most critical factor addressed by the codes. Both normal egress and emergency evacuation requirements are used in the process of establishing the code criteria. A life safety plan is

STANDARDS AND CRITERIA

often required during the plan’s review process to illustrate the path of egress and corresponding code compliance with issues such as aisle width, safe travel distance, and exit locations. The criteria required to properly create a life safety plan and additional information on maintenance and safety can be found in the NFPA 101, 102, and 5000.

Loads & Load Combinations Design loads such as Live Load, Wind Load, and Seismic Load and the combinations including Dead Load are also established by the applicable codes. The engineer of record, typically a structural engineer, is responsible for compliance of the grandstand design in accordance with these loads and load combinations. The engineer of record will seal the design drawings in accordance with the requirements of the local agency.

Some agencies may require load calculations to be provided along with the structural drawings. The load calculations will illustrate load paths and load combinations and the material and/or connection capacities used to properly address those loads.

Slip Resistance

Testing for SCOF on Wet Surfaces The National Floor Safety Institute (NFSI) is the expert source for testing walking surfaces, utilizing a state-of-the-art variable incidence tribometer to determine the Static Coefficient of Friction (SCOF). This tribometer, engineered for wet testing, mimics the heel strike of a human walking by using a leg operating mechanism that replicates the angle, velocity, and acceleration of a person slipping.

The NFSI, following the ANSI B101.1 - 2009 standard, categorizes wet SCOF into three levels: "High Traction" (SCOF ≥ 0.60), which significantly reduces slip-and-fall incidents; "Moderate Traction" (SCOF 0.40-0.59), which presents a higher risk; and "Low Traction" (SCOF < 0.40), which requires immediate corrective action.

When specifying a decking system, ensure the manufacturer has undergone NFSI's phase 2 (field) testing and has obtained a "high traction" certification. This certification incentivizes manufacturers to meet high safety standards. Always inquire about the SCOF rating and prioritize products with high traction ratings to minimize the risk of slips, trips, and falls.

Aluminum bleachers are popular for providing maximum seating and visibility at sporting events and outdoor venues. However, wet surfaces can lead to accidents, making bleacher safety a priority.

Understanding standards to reduce slips, trips, and falls is crucial.

Static Coefficient of Friction (SCOF) Previously termed "slip index" in withdrawn ASTM standards F1677 and F1679, the National Floor Safety Institute (NFSI) now uses SCOF to measure slip resistance.

With no current ASTM standards, the NFSI adopted the ANSI B101.1 – 2009 standard. SCOF measures the friction needed to prevent slippage: a higher SCOF indicates more friction, greater traction, and reduced risk of slips, trips, and falls on bleacher surfaces.

PLANNING AND DESIGN

There are many choices to make in planning a well-designed, efficient facility.

S

pectator safety should be a main concern when planning for bleachers. In addition to finding a manufacturer that can provide you with a design that meets or exceeds all recognized national standards for construction, be aware that there are a variety of options in design and finishes, as well as accessories and amenities to help promote usage and comfort.

Seating Types, Systems, and Finishes There are several seating types, systems, and finishes to consider when planning your project. Choosing the right combination to meet your needs will depend on the number of people to be accommodated, as well as the type of events to be held. In past years, the industry has made several attempts to define the differences between bleachers and high capacity bleachers. Some give consideration to the type of seat – backrest or not, individual chairs or bench seats, portable or permanent. Other assumptions have been made based on the type of support structure, such as structural steel or angle frame.

Some consider high capacity bleachers to be larger roofed structures open to one side with individual seats, while bleachers are open to the sky with seats that consist of planks. Size and venue are other criteria the industry has used to establish a difference. With the variety of options that are available, it is hard to define either by their features. Most commonly today, the industry refers to bleachers as smaller, simple structures while high 13

Make A Stand

capacity bleachers are larger and/or more complicated structures.

Generally, high capacity bleachers are located at bigger venues (e.g., stadiums, racing tracks) and seat a larger number of individuals while bleachers are located in smaller locations (e.g., high school fields and gymnasiums) and seat no more than 3,000 individuals. For code purposes, there is no difference between the two. Life safety and structural integrity are the critical objectives of the codes and the same rules apply in either case.

The International Code Council (ICC) 300 mentioned previously uses the same definition for both words which is ”tiered seating supported on a dedicated structural system of two or more rows high and is not a building element.”

The following is a basic primer on types of systems to consider; your manufacturer can assist with even greater detail to help make your choice the right one.

Spectator Seating Types Bleachers can be either permanent or moveable and come in a variety of sizes to suit your needs.

Permanent High Capacity Grandstands Also known as I-Beam or Beam and Column bleachers, permanent high capacity bleachers are custom-built to specific requirements and considerations such as seating capacity, sightlines, spectator flow, space available, and applicable building codes. They offer the

greatest design flexibility and can be designed to accommodate a number of varying site conditions such as hills or uneven terrain. Often recommended for venues of more than 3,000 seats, permanent high capacity bleachers offer the most options for customization and finishing. This type of seating also provides the most finished and spacious understructure, suitable even for buildings, such as locker rooms. This type of seating is common to racetracks, college campuses, baseball stadiums, and other large spectator venues nationwide.

High-capacity bleachers are considered custom projects, typically taking about 10 to 12 weeks to complete the entire planning process. The process begins with sales drawings, which are preliminary drawings created to generate a quote.

Once the dealer’s purchase order is received based on these drawings and the quote, the 10-12 week cycle begins. Next, submittal documents are used by the customer to verify that the designed product matches the requested specifications and site compatibility. Customer approvals are required on all submittal documents by the date listed on the drawings. For an additional fee, stamp and seal drawings, often done by a thirdparty structural engineering firm, are highly recommended. After structural markups are reviewed and final adjustments made, the bill of materials (BOM) is compiled and sent to production. Finally, production involves purchasing, fabricating, and packaging all parts listed on the BOM for on-site assembly.

Permanent and Moveable Bleachers Bleacher is the generic term given to spectator seating options that do not fit within the “permanent high capacity bleacher” category. There are fewer options to customize, though the

Non-elevated systems are designed so people in the bottom row are seated with their feet on the ground.

systems available in this classification do offer a variety of alternatives. Bleachers can be permanently affixed to the site or remain portable to facilitate movability. See additional information on bleachers in the Resources section of this guide.

Bleacher Systems Non-elevated Systems Non-elevated bleachers are a simple structure with a first row seat height of 17", so people seated here will have their feet on the ground, eliminating the need for additional walkways or stairwells.

They are generally used outdoors and should be anchored in place to protect them against adverse wind situations.

Elevated Systems This structure was designed to elevate the spectators’ line of sight to improve overall event viewing. An elevated system would generally include an elevated front walkway platform with front guardrails, entry stairs and/or accessible ramps, aisle(s) with handrail, a riser plank, and a double foot plank on all rows.

Angle Frame Bleachers Angle frame construction can be a more affordable design for large seating structures. These can be made permanent by anchoring to a concrete slab or left portable for movement on a park property for different settings. Typically, deciding between permanent high capacity bleachers or bleachers depends on the desired seating capacity. Due to the cost associated with the slab foundation for a 1,200+ seat angle frame bleacher, the overall price approaches that of a permanent high capacity bleacher (about a 25% difference in cost).

Elevated systems improve spectators' line of sight and overall event viewing.

PLANNING AND DESIGN Low Rise Systems Created to allow more rows of seating without the need for aisles or guardrails, this structure has a lower first row seat height at 12", a 12" seat plank (deeper than standard 2" x 10" for added comfort), and a 6" rise per row. The 3 and 4 row low rise systems are under the 30" benchmark, and require no aisles and guardrails according to ICC300. Low rise systems are also available in a tip and roll model to allow for flexibility and transport.

Tip and Roll Systems This system is an excellent option for indoor auxiliary seating. This versatile system can be tipped up and rolled away for convenient storage when not in use. It is available with 2, 3, and 4 rows and can be ordered as a low rise system.

The system comes standard with a lighter aluminum understructure to make lifting to an upright position easier. Heavy non-marring rubber foot pads positioned underneath the frame protect indoor flooring. When tipped up it rests on durable 5" caster wheels for easy movement. A locking rear wheel restricts

movement when it is stored. The 4 row configuration has a folding outrigger for added stability and safety. Because of the height restrictions, the 4 row models are only available in a low rise option.

Transportable Kit Often, seasonal events held at multiple fields located at the same complex do not require permanent bleachers. Transportable kit systems are an affordable and alternative system to permanent bleachers that can be used at multiple fields. They are designed with additional frame bracing to withstand the rigors of movement. A transport kit is required and includes the wheel assembly, tongue assembly, and optional lifting jacks. One transport kit can be used for multiple transportable bleachers.

These structures are available in 5 and 10 row models. The kit is often a good solution for budget minded individuals. It is important to note that transporting speed should not exceed 5 MPH, and use on public roads is prohibited.

Bleacher Models All bleacher models are made up of components, including seats, foot planks, and guardrails, as shown in the illustration below. Each model has its own requirements for safety regulations, and many offer variations to promote comfort and usage.

Please see the Glossary section in the back of the guide for a list of component descriptions corresponding to this illustration.

Standard Bleacher Model Designed to meet guidelines and maximize affordability, this streamlined model offers single foot planks on row 2 and 3, and double foot planks and riser planks on rows 4 and up (excluding low rise bleachers). Guardrails are required when seating is 30” or more above the floor or grade below, as per Section 408 Guards ICC 300. For systems with 4 rows or more, a chain-link or

vertical picket guardrail is available. The standard model is usually available in 2 to 10 row systems in most lengths.

Preferred Bleacher Model Double foot plank on all rows, riser planks on rows 4 and up (excluding low rise bleachers), and chain-link or vertical picket guardrail on systems with 4 rows or more.

Deluxe Bleacher Model The deluxe bleacher model is available in 3 to 10 row systems in most lengths but are not available in low rise or tip and roll.

Bleacher Skirting Options Skirting refers to the covering or fencing that encloses the area beneath bleachers. It serves multiple purposes, including enhancing safety, improving aesthetics, and reducing maintenance. By covering the framing of bleachers, skirting helps prevent unauthorized access, keeps debris and vegetation out, and maintains a clean, orderly appearance. Skirting can be made up of either riser plank, PBU metal panels, or chain-link.

Seat Types: Bench or Chairs Seats can either be benches (seat planks) or chairs. Adding a backrest also promotes comfort. When designing with chairs, it is important to note that individual chairs can be fixed or they can fold depending on needs.

When deciding on the type of seat to be used, there are a variety of questions to address. Plank seats are generally more affordable, and will take up less space than a chair. Chairs provide fewer seats in a linear space, as they are based on a 20" wide calculation, as opposed to 18" for plank seats.

In regards to seating capacity, there are two terms used— “Gross Seats” and “Net Seats.” A seat is defined by 18" of “space” when add a space using a bench or plank seat, or 20" for a chair with armrests.

Chairs also require a greater tread depth (generally 30"), as the tread must accommodate both the chair and the space needed for a person to comfortably pass in the row.

Gross seat count is the capacity of the grandstand without aisles, ADA cutouts, or vomitories where seats would be removed, and is determined by taking the length of the grandstand, dividing by 18" and multiplying by the number of rows.

Fixed chairs will require more tread depth (minimum 33") than folding chairs. Folding chairs can be designed with “gravity lift” or “spring loaded” hardware so that they fold when the person stands. Typically, folding chairs have a deeper seat area for greater comfort. Both chair types typically come with seat number plates and aisle letter plates, and can be ordered with optional cup holders.

Net seat count is the same calculation minus the area where seats would be removed for aisles, ADA cutouts, and vomitory locations.

PLANNING AND DESIGN Finishes There are a variety of options available when considering the finish that is most appropriate for your project.

•

Anodized Aluminum Anodizing is an electrochemical process that converts the surface of aluminum into a decorative, durable, and corrosionresistant anodic oxide finish. This process involves creating a thick, porous oxide layer that fully integrates with the aluminum substrate. Unlike coatings that can flake or peel, the anodized layer becomes part of the aluminum, providing a resilient surface that maintains its integrity even if scratched. The anodized finish has a highly ordered structure that can be further treated for coloring or sealing, offering a range of finish options to suit different needs. Common finishes include satin clear, brite-dip clear, and various colors, tailored to the project's specific requirements and environmental conditions:

•

• • •

15-minute satin clear: An economical choice for costconscious projects.

30-minute anodize: Standard for inland projects, offering several years of durability.

60-minute anodize: Ideal for environments within a mile of saltwater, treatment plants, or other harsh atmospheric conditions.

Benefits of Anodized Finish Aluminum: •

No Staining: The anodized surface resists staining, maintaining a clean look.

•

• • •

Heat Resistant: Capable of withstanding high temperatures without degrading.

Easy Maintenance: The smooth surface is easy to clean and maintain.

Durable: The anodized layer increases the aluminum's hardness and resistance to wear.

Corrosion Resistant: Highly resistant to corrosion, even in harsh environments.

Environmentally Friendly: The anodizing process is ecofriendly and extends the aluminum's lifespan.

Food Safe: Suitable for food contact, making it ideal for kitchen equipment and food storage.

With a life expectancy of 20 to 30 years with proper maintenance, anodized aluminum offers a reliable and long-lasting solution for a wide range of applications.

Hot-Dip Galvanized Steel – Zinc Finish Hot-dip galvanizing (HDG) is the process of dipping fabricated steel into a kettle or vat containing molten zinc. The process is inherently simple which provides a distinct advantage over other corrosion protection methods. While the steel is in the kettle, the iron in the steel metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to steel.7 HDG Process: The hot-dip galvanizing process consists of three basic steps: 1) surface preparation; 2) galvanizing; and, 3) inspection.

Below, is an illustration of these steps:

Hot Dipped Galvanized surfaces provide durability and minimal maintenance.

Powder coating provides a colorful finish that is more durable than paint.

The array of color choices can match the overall stadium design.

Powder Coated Aluminum Powder coated aluminum involves pre-treating, then applying a dry powder paint, consisting of finely ground pigment and resin, to an aluminum product by way of electrostatically charging the powder and then spraying it onto the product.

PLANNING AND DESIGN Mill Finished Aluminum Mill finish refers to the surface or texture of the aluminum after it exits the mill, extrusion die, or drawing process. It usually lacks luster and can have oxidation spots present.

When exposed to the outside environment, a mill finished plank will generally “oxidize” to a uniform gray appearance. If a mill finished plank is used as a foot board, the coating exposed to foot traffic will wear off over time.

The finish would not be uniform as the plank will not experience the same level of foot traffic uniformly across the plank. The oxidation of a mill finish aluminum plank has no negative impact on the strength of the extrusion.

Mill finish aluminum will stain when moisture is trapped against it. This moisture entrapment can occur at several stages of material delivery to a jobsite. The stages include packaging, shipping, and storage at the site. These stains can occur at any time and, depending on the environmental conditions, can develop rapidly. The stains can be erratic and vary in color from light bronze to black to chalky white. The stains will generally blend in overtime and in many cases disappear

almost completely when exposed to the sun.

All aluminum bleacher manufacturers experience the same challenge with regard to mill finish aluminum and have, in the past, attempted to clean the foot boards after the bleacher has been erected. This has proven to be unproductive as the cleaning process makes the deck of the bleacher look worse than prior to the cleaning since the “cleaned” product is splotchy in appearance.

For that reason, the industry typically recommends allowing nature to take its course and letting the sun “bleach” the plank to a uniform gray appearance. It is also important to note that staining will occur immediately after the first event due to spillage by the spectators. When water becomes entrapped between warps of the aluminum surface, the aluminum can be stained a chalky white color. This may pose problems for the contractor or distributor, who may be surprised to find out that the mill finish aluminum is no longer bright and shiny, but exhibits a white, chalky stain.

Benefits of Anodized Aluminum: •

Inexpensive

•

Low maintenance, but owner must be willing to accept stains and natural appearance of the product

The bitterness of poor quality stays far longer than the sweetness of a low price.

- Ben Franklin

These images help to illustrate the staining common with mill finish aluminum.

While it is an affordable option, the site owner must be willing to accept the weathered look common with this material.

Design Considerations Maximizing Your Space In angle frame structures, space underneath the seating is nonexistent in that the framing and cross bracing required for this type of structure utilizes that space.

Good designers are skilled at maximizing space in sites with tight space requirements, and will know how to make adjustments to meet the needs of each facility.

Seating Capacity As mentioned earlier, seating capacity for the grandstand/bleacher industry is typically identified by 18" per seat. This is an industry standard and not necessarily what customers may view as ideal. In chair seating with armrests, 20" per chair is typically used.

In some states, for high school playoff games, 24" per bench seat is required for seat widths. It is recommended to check the local high school rules association for specific determination of required seat capacity.

ADA Compliance and Accessible Seating To maintain ADA compliance, it’s essential to provide the required number of wheelchair-accessible spaces based on your stadium's total seating capacity: • • • • • •

1 space for 4-25 seats 2 spaces for 26-50 seats 4 spaces for 51-150 seats 5 spaces for 151-300 seats 6 spaces for 301-500 seats For 501+ seats, 6 spaces plus 1 additional space per 150 seats

Additionally, ensure these accessible seating areas are distributed throughout the bleacher system, offering various viewing angles and making it easier for all attendees to find suitable seats.

This not only enhances accessibility but also improves the overall experience for everyone in the community.

PLANNING AND DESIGN Sightlines for (8" x 24") treads

Sightline “Sightline” is a term used in the seating industry to determine the spectator’s ability to see the field of play from their seat over the head of the spectator in the row in front of them.

Sightlines can be enhanced through a steeper pitch of the seating rows, lowering the front row elevation, or increasing the distance of the focal point on the field from the actual seating rows. When selecting a bleacher or grandstand, take sightline into consideration when designing your space.

Knowledge of the factors involved in sightline allows fans to have the ultimate experience and clear viewing at every venue.

Sightlines for (10" x 24") treads

Projects pursuing LEED certification earn points across several areas that address sustainability issues.

Based on the number of points achieved, a project receives one of four LEED rating levels.

PLANNING AND DESIGN Amenities and Accessories There are a variety of site amenities and accessories that should be considered when planning spectator seating venues to help promote function, comfort, transportation, sanitation, and even gathering spaces and family activities to help retain visitors and spectators. Enhancing the overall user experience can greatly impact visits.

Team Benches Team benches come with a galvanized or aluminum angle surface mount frame or a galvanized in-ground mount frame.

Seats are usually 2" x 10" or 2" x 12" with optional backrest of 7". Standard lengths are 7'-6", 15', and 21' but can be customized as needed.

Press Boxes Press boxes can be custom designed to meet finish and layout needs. They can include HVAC, camera deck, slider windows, security shutters, interior rooms, and custom exterior colors.

The standard depth is 8' with standard widths beginning with a 12' minimum, and growing in 6' increments. These can also be customized depending on needs and space available. There are two framing options, wood or metal studs, while the exterior siding can be vertical vinyl panels or steel rib panels.

Team benches are a great addition to provide teams a place to gather and rest.

Shade For games or events held during the day, shade structures can help protect players and attendees from the sun’s rays. There are two types of shade structures found in the grandstand/bleacher industry.

The first one is a self-supported “fabric” shade structure made up of steel support columns and colored fabric shade materials. This structure type is built for sun protection rather than moisture and may need to be removed in extreme weather.

Another shade structure option is designed to be incorporated into the grandstand. It can be “cantilevered,” with columns only at the rear of the stand to maximize sightlines, or it can have columns toward the front of the structure, depending on the seating area depth.

Typically, supports are made of the same steel as the grandstand structure. The “cover” of this system is typically steel “R” panel and can be finished in Galvalume® or Kynar painted finish. The shade and the grandstand together would be required to meet all wind/ snow/live loads for the area.

Benches are also a great addition for family seating.

Shade structures help provide comfort protect players and fans from weather conditions.

Bike Racks Consider that some attendees may choose to bicycle to the event, so be sure to provide bike racks that provide a way to lock the frame and at least one wheel to the rack. According to a leading bike rack manufacturer, assume 5-10% of attendees will arrive by bike, but this may depend on how bike-friendly the community is. There are also “event racks” available, which can be stored when not in use, and are a great idea if the stadium will host different types of events that have fluctuating interest from bicyclists.

Trash Receptacles It is critical to offer receptacles for trash and recycling to ensure the facility remains clean and to help reduce the cost of onsite maintenance. Locate them near the entrances to the grandstand/bleachers, and around other areas like concession stands, restrooms, and parking lots.

Picnic Tables For events where concessions will be sold, offering picnic tables ensures that guests have a comfortable place to sit and place the food they are eating, as opposed to walking back to the stands and balancing it on their lap. Picnic tables also help control waste, as people can dump their food waste and recycling in containers located near the picnic tables.

Do not forget event attendees who may eat and drink in the grandstands; providing additional waste receptacles near the access/egress points will also help control litter and minimize clean up time after an event.

Offering trash receptacles for trash and recycling ensures the facilities remain clean.

Scorer’s Table These tables are specifically designed to accommodate persons keeping score. Depending on the sport, more than one may be needed for each team, and/or in multiple areas along the sidelines.

Benches Benches can increase accommodation when strategically placed in gathering areas. Consider placing them near restrooms, concession areas, ticket booths, and alongside the playing field to accommodate athletes, coaches, and scorers.

Playgrounds Sporting arenas, especially those that draw large crowds, are increasingly adding fun amenities like playgrounds to help provide additional activities to engage young children. With a variety of theming options available, they can be designed to create an extension of the arena’s theme, sport, or architectural features.

Restrooms While restrooms can be incorporated into permanent grandstands, they need to be considered in all applications to ensure spectators have access to them while attending events. If permanent restrooms are not an option, temporary facilities can be brought in to handle the crowds. A general rule of thumb is one portable toilet for every 50 people attending the event. Do not forget to consider accessibility when planning these facilities.

Bike racks can also be themed to coordinate with the facility’s usage, like the baseball racks shown above.

Offering tables and trash receptacles near concessions helps control litter and post-event maintenance.

PLANNING AND DESIGN Training Rooms In today’s competitive team landscapes, great facilities are an expectation. Facilities with great training rooms elevate their appeal, and they can be designed to meet a variety of budgets and room size specifications.

Turf Fields Synthetic turf systems can help reduce maintenance, increase aesthetic appeal, and optimize the performance of athletes. Look for turf systems made in the USA, in fully integrated manufacturing processes, to help promote quality and serviceability.

Surfacing A variety of surfacing options are available for multiple areas throughout the facility. Besides the playing field, surfacing can be used to create recreation areas, or to provide visual cues to assist attendees in finding concessions, eating areas, or

Themed play spaces like the one shown can provide additional fun for young fans while encouraging sports participation.

other designated areas. Surfaces can be made of compressed rubber, artificial turf, colored concrete, or other materials.

Concessions Concession stands are generally included in permanent grandstands. For bleacher facilities, consider allowing licensed vendors and food trucks to provide beverages and nutrition.

This can also be a great opportunity for a fundraiser for the school, team, or facility.

In summary, there are a wide variety of spectator seating options, finishes, and considerations in creating a facility that is comfortable, accessible, and enjoyable. Utilizing the checklist following this section will help you to identify the basic needs, provide your manufacturer with an outline of your goals to properly align the budget and timeline, and help to ensure a successful partnership!

Planning and Design Checklist When planning for new or replacement bleachers or grandstands, it is a good idea to start with a checklist to help identify needs and priorities. The checklist on the next page is a great place to start, see the Glossary session in the back of the book for definitions of unfamiliar terms. Your bleacher or grandstand manufacturer can be a great asset in this part of the process, as they can assess your site, listen to your

needs, and help design the correct type of structure to meet your particular applications and priorities.

Organizing a committee of stakeholders to help drive the project forward can be very helpful. For larger projects, this may consist of several committees in charge of oversight, planning, steering, funding, logistics, and marketing.

Ensure that the public is involved in the process to promote community engagement, buy-in, and long-term support.

Using a checklist for planning and design will help ensure the finished project aligns with the vision for design and functionality.

Inspection and Care Inspection A general guideline for bleacher inspections is to perform them at least quarterly or seasonally, or if available, to the manufacturer’s specification. The checklist on the next page may provide a good starting place, but before undertaking an inspection and maintenance schedule, it is a good idea to check with your local building inspector to learn which building codes the city follows and if they have specific guidelines in regard to inspections. The frequency may depend on state laws, local ordinances, or the manufacturer’s warranty specifications. According to the ICC300 standards, existing tiered seating shall be maintained structurally sound as follows: Structural 1. Components or fasteners shall not be broken, damaged, badly deteriorated, or missing.

2.

dequate bearing shall be provided. The structure shall A bear uniformly on the floor or ground in a manner so as to safely support the structure.

3.

Case Study: A Study in Design and Community Collaboration Kiggens Bowl, Vancouver, Canada

Original Kiggins Bowl before renovation.

A 95 Year Tradition Kiggins Bowl stands as a cherished symbol of Vancouver's sporting heritage, tracing its roots back to the vision of Mayor JP Kiggins, who, in 1930, transformed a plateau within the newly donated Leverich Park into a thriving athletic complex. By 1933, it had become a sprawling venue capable of accommodating three football fields, surrounded by a half-mile running track and a baseball diamond, nestled within a natural amphitheater. The ambitious construction of the stadium commenced in 1937 and culminated in the grandstand's completion in 1939, a project costing $200,000, equivalent to $4 million today.

Despite its grandeur, Kiggins Bowl faced initial skepticism, with a National Recreation Association Representative branding it a "monstrosity" ill-suited for sporting events. Yet, through perseverance and community support, the stadium underwent successive rounds of renovations. In November 1945, lights were installed, and the bleacher section received an extended roof, transforming the stadium's amenities. However, challenges persisted, such as inadequate drainage, earning the venue the notorious nickname "the soup bowl" by 1967. Yet, the resilience 39

of the community shone through in April 1968, as a grassroots fundraising effort revitalized the stadium, installing new lights and a modern drainage system.

The evolution of Kiggins Bowl continued into the modern era, marked by milestones such as the installation of artificial turf in the summer of 1997, making it the country's first artificial turf field.

Later renovations, including replacing turf in 2008 and renaming the stadium to "Boggs Field" in 2011 in honor of Coach Boggs who led the local high school team the “Trappers” from 1965 to 2000, further cemented its status as a cultural landmark.

“Once I learned about the scale of renovation that was planned, I said, ‘Why don’t we just tear it down and start from scratch,’” Chuck Stiller, Vancouver Public Schools Projects Manager, said, “And the reaction I got was like I had just killed someone’s dog.”

While renovating historic sites like Kiggins Bowl may not always be the most cost-effective solution, it is crucial for preserving community heritage and maintaining cultural landmarks.

Following decades of service, Kiggins Bowl recently underwent a monumental transformation, representing the most significant

Case Study: Updating or Replacing? That is the Question Grove City High School, Grove City, OH

The transformation of the Grove City High School stadium resulted in a destination that is the central location of all community events. Photo courtesy of www.grovecityohio.gov.

A Safe Stadium for Everyone The South-Western City School District is the 6th largest public school district in the State of Ohio covering 119 square miles including urban, suburban, and rural settings.

This is one of the most unique districts in the state of Ohio.

Grove City High School is one of six high schools in their system. Formerly known as Jackson High School, Grove City High School offers a music program with over 300 wind, percussion, and string musicians, which has received over 30 Grand Champion awards over the last 10 years in the Ohio Music Education Association (OMEA) competitions. In addition, the high school hosts football games throughout the year.

building requirements, the railing was not up to code, and the structure was not accessible. Furthermore, the structure was particularly unstable when at full capacity. South-Western City Schools decided it was time to update the district’s facilities but needed help deciding to either upgrade or replace completely the visitors’ football bleachers structure. They enlisted Schorr Architects, Inc. to help made the decision.

A comparison study was made to gather information on the cost for a new structure versus upgrading the existing one.

The district decided to replace the bleacher with a new 2,000 seat structure while the architectural firm developed a cost effective angle frame bleacher assembly solution for the new project. In February 2015 the project was advertised and went to bid. The district hired a contractor that was able to provide them with a turnkey bleacher project. They completed the removal of the original bleachers, the extensive concrete site work, did the landscaping, installed the fencing and railing, and even took care of the electrical site work. They were able

Replacing our bleachers was a better investment for us than updating the existing structure.

We are happy we did! We are now able to serve our high school as well as the community by hosting events opened to the public while knowing everyone is safe.

to work around an existing structure behind the bleachers that houses another facility and a nearby a cell tower. The demolition phase started and was complete in February 2015.

Weather did not help thanks to heavy snow through the area, as there was a waiting period until the ground thawed and dried out enough to complete the concrete site work.

Today, Grove City High School offers their guests a new 15 row x 235'-6" elevated bleacher, including ADA accessible seating, appropriate entrances and exits, code compliant railing, and a stable and safe environment for everyone to enjoy. With a total net seating capacity of 1,988, the bleacher was shipped in early May 2015 and was completed by early June 2015, ahead of the project deadline. The project was such a success that they have even opened the space to others in the community; for example, for 4th of July weekend the adjacent community will display fireworks and the school has graciously allowed members of the community to use their bleachers to enjoy the view.
