What Are Grandstands?
A grandstand is a large area of seating for spectators at an entertainment show/event that is sometimes covered by roofing.
It is comprised of rows of seating that are sloped upwards. This could be rows of individual seating or bleachers.
The arrangement of rows will provide a sightline to all spectators to see the main stage or area without an issue.
Grandstands in summary are larger versions of bleachers with continuous rows.
However, grandstands can be designed a few ways with the most common setup as one large grandstand (large bleachers).
They can also be set up surrounding the stage/field/court on three sides or all sides.
This is done in either a continuous arc shape or separate bleachers.
Figure 1 Grandstands Arc Example
What Is The Main Purpose For Venues To Use Grandstands?
Grandstands have been around since ancient Rome.
They look a little different today but have been around in college sports history since sports started. Harvard Stadium is the oldest college stadium grandstand today.
It doesn’t look like today’s traditional grandstands but the structure resembles it dating back to 1903.
This allows spectators to be seated comfortably and no matter where you are position in the stadium, you can see the event with good visibility
Grandstands can also be space-efficient providing restrooms, concession stands, and more underneath and throughout the structure.
Grandstands are also a cost-effective way for venue owners to set-up stadium seating.
This is especially true when you use bleacher-style grandstand seating.
What Are Grandstands Made Of?
Grandstands can be made from a wide variety of materials or used in a combination in order to offer the best product available.
More often than not you will see the combination is what is most popular in today’s options.
This is because certain aspects of grandstand seating have developed and certain materials fare better for certain parts than others.
Harvard Stadium is a great example of grandstand seating that is outdoors and made solely of cement and concrete.
It is a non-tiered grandstand that has concessions, locker rooms, and entry and exit ways underneath the seating and structure.
This is much less common in today’s grandstands though because of the lack of flexibility when maintaining.
Usually, the individual chairs made in outdoor grandstands are made of hard plastic that is weather-resistant.
Most of the chairs are made of high-density polyethylene which is one of the world’s most commonly used plastics.
This is because HDPE is lightweight and durable. It’s also very easy to mold making it perfect for customizing grandstand seating.
Sometimes the entire structure of grandstands may be made out of aluminum or a different type of metal.
If the chairs are made out of hard-plastic then there is a good chance that the base of the chairs will be made out of strong metal.
Grandstands themselves as a structure are often made of some type of metal because it provides a safe and durable structure.
Aluminum is non-conductive and has a weight-strength ratio that is hard to beat. This is why it’s a great choice for safety.
Steel however becomes a popular choice because it is often galvanized adding serious longevity to its lifespan.
The zinc prevents the metal from rusting out and causing any sort of safety violation with regulations.
Galvanized steel is a little heavier than aluminum but is often the best choice for permanent structures.
Some grandstands are made of wooden bleachers or individualized wooden stadium chairs.
Before Fenway in Boston was the all wood-built grandstand The South End Grounds in 1871.
This was one of the many baseball grandstand parks at the time that was built solely from wood.
This beautiful grandstand could seat 6.800 comfortably and be rebuilt twice in its lifetime. Once by choice and the other was necessary.
Figure 2 The South End Grounds
What Are The Different Types Of Grandstands?
Grandstands can either be permanent or temporary.
In a lot of cases, grandstands are permanent for pro sporting events like baseball, the NFL, or the NBA.
In some other cases, the event may only happen once a year or the budget may be lower due to a small crowd. This would be a better scenario for temporary seating.
The Churchill Downs Horseracing Track in Louisville, Kentucky is a great example of a permanent grandstand structure.
They consider the first-floor seating arrangement to be their grandstand area.
However, technically the whole thing can be considered grandstand seating.
The past year the Miami Open professional tennis tournament created a temporary grandstand inside the Miami Dolphins arena.
This is different than their permanent grandstand outside the stadium.
Often the parts made for temporary seating are all similar in order to effectively set up and break down the grandstand efficiently and quickly.
Figure 3 Temporary Grandstand Seating At The Miami Open
Who Uses Grandstands?
Anyone that needs to seat groups of people, so that they can all see either the presentation or the show, can use grandstands.
It’s very common for places like schools, sporting events, and conventions to use grandstand seating.
Regardless of whether you have a small crowd or a large crowd, grandstands can range from small bleacher grandstands to large grandstand stadiums.
Grandstands for schools
Gymnasiums for schools typically use bleacher grandstand seating because it is an affordable way to seat as many kids as needed.
As mentioned above, it can also be space-efficient by putting in retractable seating.
Grandstands for Sports
Another common use for schools of all levels, elementary through college, is to use grandstands for sporting events.
It is very common to see a grandstand set up around track, tennis, soccer, and many more sports.
This is because oftentimes the school may only set up one or two sides of large bleachers and sections (grandstands) for the expected number of spectators.
Are There Different Sizes For Grandstands?
Grandstands typically cater to medium and large crowds as grandstands count as bleachers and also as stadiums.
When they accommodate smaller crowds this can just be called bleachers.
The Grandstand section of the Miami Open (not the Hard Rock Stadium) is a permanent structure that can host 5,000 seats.
Figure 4 The Grandstand In Comparison To Miami Open Stadium
This is located next to the semi-permanent stadium grandstand located in the Hard Rock Stadium.
The Grandstand here is considered a medium-size capacity.
The Miami Open Grandstand is made up of several sections, encloses the court, and has no roofing.
The center court at The Miami Open is a grandstand stadium with a capacity of 14,000.
This is the beginning tier of a larger grandstand stadium.
Larger grandstand stadiums look similar to Lusail Stadium, which will hold the FIFA 2022 World Cup.
Lusail grandstands can seat a total of 80,000 people with a grandstand on each side of the field.
Figure 5 Lusail Grandstands Large Grandstand Example
What Are The Dimensions Of Different Grandstands?
While all dimensions of grandstand seating can vary, there are some common figures within the size categories that can give or take a little.
The Wuhan National Fitness Center seats 4,000 spectators and is a two-level grandstand
The dimensions of this grandstand center have a height of 13.6 meters or 44’ 7.433” and a seat width length of just under 18 inches per seat.
The Michigan International Speedway has a massive capacity of 132,000 with 40 rows of grandstand seating.
After renovations, the racetrack went from three separate grandstands to one large grandstand.
This means that about 3,300 seats sit in each row spanning roughly a half-mile long to watch the two-mile-long racetrack.
What Is The Range Of Costs For Different Types Of Grandstands?
Grandstands have a number of variables that would alter the cost for a venue owner, designer, or contractor.
For more affordable seating you can expect to pay $50-$150 a seat.
This would not include any upscale features like individual seating. This is most likely planks of steel, aluminum, or wood in a bleacher setup.
For more upscale grandstand seating that looks like the Vogue Series, this may cost you upward of $200 to $500.
The more customization and additions you add to grandstand seating the more expensive it will get.
It also will depend on the type of materials being used and the weight because this will increase the shipping costs.
Figure 6 Vogue Series Grandstand Seating
Are The Replacement Costs Of Grandstands Expensive?
With large grandstand stadiums such as the Michigan International Speedway, renovations can cost multiple millions if you plan on making major upgrades.
This especially applies if you are working with cement grandstands as it is a much more permanent structure and changes cannot be made without drilling and recementing.
However, most replacement costs don’t come anywhere near this.
If you are replacing an entire individual chair, the replacement cost will most likely cost you what you paid per seat or slightly less.
If you need to replace an entire plank (wood/metal) this will also resemble costs per seat.
However, most of the time you can get away with replacement parts which makes it much more affordable.
What Warranties Are You Guaranteed With Grandstands?
Warranties last up to five years with the exclusion of man-made damages.
Man-made damages do not include loose parts or weather damage.
You can expect to have constant communication with the sales team during this five-year period.
When the guarantee period is over you can still ask for after-sales services to maintain your grandstand structure.
Do Grandstands Have Personalized Seating?
Some grandstand venues may have personalized sections dedicated to high-ticket holders.
This may come in form of boxed seating, premium seating, or even standard seating with dedication labels if a seat has been bought.
Not all seats in a grandstand have to be the same even though the majority of them are.
To What Level Can Grandstands Be Personalized?
Grandstands can be personalized in a number of ways.
While you can buy standard grandstand seating, this is for more basic orders that would go to a small school gymnasium.
Larger grandstand orders are typically customized in colors, a number of seating, additional amenities, and measurements to accurately surround the entertainment area.
Parametric design is the system used that is calculated on the computer to provide the best sightline possible and may stray away from traditional geometric shapes.
Essentially, this provides the customization you need that will best suit your spectators and provide the most logical solutions for your grandstand seating.
How Do You Set Up A Grandstand?
This depends on whether you are setting up a temporary or permanent structure.
Guidelines and regulations will apply to both types of a grandstand but the size is really what makes a difference here.
Larger orders have a much different type of setup.
This will require a crew to follow the safety standard and guidelines of a grandstand stadium setup.
If you have bleachers without personal seating this will be an easier set up than installing each individual chair.
What Is The Difference Between Grandstands With Individual Seating Verse Bleachers?
Grandstands can come in many varieties but the main two forms are grandstands with individual seating and without.
More upscale grandstands usually have individual seats attached to bleachers or rows.
This may be a plastic chair with backing or a seat without.
Grandstand bleachers can just remain bleachers not having any distinguished space between spectators.
What Are Bleachers?
Bleachers are a type of grandstand seating but are more commonly referenced on a smaller scale.
They function in the exact same way a grandstand structure does as the model is the same.
They are comprised of rows of benches that raise in a tiered-fashion.
This is to ensure everyone has a good sightline without obstructed views no matter where your seat is.
Figure 7 Bleacher Example
Is Grandstand Seating All Economy Seating?
A grandstand can have all different types of seating depending on how advanced the structure is.
The majority of seating will be made up of economy seating but a grandstand is likely to offer premium seating as well as box seating.
Premium seating most likely will be towards the front of the grandstand offering up-close views.
VIP seating is either in the middle of the grandstand if divided into two tiers, or at the top of the grandstand.
VIP seating offers completely private rooms and sections as a stadium would for exclusive seating additional features like private bathrooms and kitchenettes.
How Many People Can Grandstand Seating Accommodate?
Grandstands serve a wide-range of accommodated seating options from medium-size orders to world-class large grandstand stadiums.
The Bristol Motor Speedway is one of the largest racetracks accommodating 146,000 spectators.
Working its way down from here, you can find all sorts of capacity seating numbers.
A few thousand spectators can be accommodated at the Miami Open Grandstand, while gymnasiums may need just a few hundred spots or less.
Figure 8 Bristol Motor Speedway
How Long Does It Take To Manufacture Grandstands?
Grandstands typically can be made within 30-45 days for general orders.
General orders will be grandstands ordered with minimal alterations or the need for major-specific dimension customizations.
For orders that exceed 40,000, this timeframe will be extended closer to two months and beyond.
A good measuring order for a timeframe is to account for 6,500 stadium chairs to be mass-produced a week.
For bleachers without individualized seating, the timeframe is much quicker due to standard and simplistic parts being mass-produced over and over again.
What Would Affect The Timeline Of Manufacturing Grandstands?
The more customization a project requires the more time should be added to the manufacturing period.
This can be factors like the color of seating. How many colors are being used and in what layout based on the design.
Also customized seating measurements for different types of seating like the economy, premium, and boxed seating will have an impact on the general timeline.
What Is The Expected Timeframe To Set Up Grandstands?
Grandstands are not only cost-effective but are easier to set up than most types of seating.
This is generally because of their simplistic design setup. The length required for setup will depend on the order size.
With medium orders usually being around a few thousand, this may seem like a tall order, these grandstand orders can typically be installed from a few days to a week.
This can take longer depending on how large the order is as there is a wide-range from tens of thousands to over 100 thousand.
This will largely depend on the complicity of the order along with the design layout.
As noted, large orders have a lot of customization with measurements and design for the most optimal functionality.
This means the implementation of this design will take a few weeks to maybe a month and a half depending on the crew size installing it.
How Many People Do You Need To Set Up The Grandstands?
Orders that make their way to accommodating thousands can certainly have a handful or two of crew members to get the job done faster.
It’s important to have more people on board if there is individualized seating in the grandstand rather than just a bleacher set up.
These orders need to have a dozen to two-dozen worker’s hands for transporting and installing the materials.
The more customized a grandstand stadium is the more hands you need on deck as well.
The installation of premium seating will be different than those of boxed seating and the general economy.
Having a person dedicated to a specific type of seating is more efficient than having one person do all of it.
What Regulations Do Grandstands Need To Follow?
There are different regulations for different types of grandstands.
Outdoor aluminum bleachers will have a different set of requirements than indoor hard-plastic retractable grandstands.
However, the National Fire Protection Association has a set of standard guidelines that all grandstands need to follow.
They cover a range of safety issues such as life safety, weather safety, fire safety, and more. There are more than 300 codes.
Here are the more common ones for a small sense of what you need to know.
- The grandstand needs to meet the fire code which includes fire-resistant materials and efficient pathways for exit in case of fire.
- Sizing per grandstand section should meet safety requirements which should remain less than 10,000 square feet and remain 20 feet apart from each other should there be multiple sections.
- Annual inspections must be done in order to maintain safety by ensuring all structures are intact and functioning properly.
- Freestanding structures must provide safety structures to open areas of bleachers like the top where backing should be placed and the stairs/sides, where there must be railing.
- Outdoor bleachers (aluminum) must be environmentally safe from storm weather conditioning. They should not be conducive to lightning.
As mentioned, these are just some of the many codes grandstand and bleacher seating must follow.
Are Grandstands Lower-Maintenance Compared To Other Types Of Stadium Seating
Besides the five-year guarantee and warranty, grandstands are typically a low-maintenance type of stadium seating.
The more simplistic a grandstand is the less maintenance will be required.
For grandstands that have individualized seating, the more you will have to take care of it.
Individualized seating naturally has more parts and can be broken more easily than a long plank.
How Do You Properly Care For Grandstand Seating?
Whether your grandstand seating is low-maintenance or not they need to be adequality looked after for a multitude of reasons.
There are many reasons but safety, cleaning, and updating your grandstand seating to follow protocol and ensure a proper environment for your guests are the most important things.
Regardless of size, the grandstand needs to be checked frequently for any safety hazards that may come up.
If a part is loose or the part is not functioning the way it’s meant to be, this can later become a safety hazard and needs to be immediately fixed.
It’s a good idea to go through a maintenance checklist that covers every part of the grandstand once a year.
In order to increase the longevity of your grandstand, it needs to be cleaned often.
This is not only for hygienic purposes for your customers but also because dirty seating can cause wear and tear on the seats.
This is especially true for leather and fabric seating.
While bleachers and grandstands have come a long way since Ancient Rome, they are still constantly adapting to modern standards.
For instance, with the inclusion of technology in everything, the electrical work for any charging stations must comply with electrical and fire codes.
Are Grandstands Only Meant For Outdoor Seating?
Grandstands can be an indoor or outdoor structure.
Often traditional grandstand structures are outdoor grandstands with roofing covering some of all of the seating.
Grandstands were originally created with outdoor sports in mind such as horse racing, car racing, tennis, etc.
Most grandstand seating materials were also designed in mind to brave the weather such as galvanized steel, hard plastic, and durable wood.
Can Grandstands Work In A Tiered Stadium?
Grandstands technically can be layered as the Wuhan National Fitness Center has two levels of grandstand seating.
Figure 9 Wuhan National Fitness Center Tiered Grandstand
However, in most cases, you might find grandstand seating to be longer rather than taller.
Grandstands are essentially oversized bleachers that may stand alone or wrap around the racetrack or event stage.
The most common example of a tiered grandstand seating is baseball fields like Fenway Park.
Do Grandstands Have Any Amenities Or Additional Features?
Grandstands leave a large portion of the seating to standard seating or economy seating.
In this case, most of the chairs will be exactly the same. However, these chairs may have additional features to make the user experience more friendly.
Because of how large their structure is, there is also ample room for design space under the grandstand.
This space may include several types of rooms such as meeting and locker rooms, concession stands, and gift shops, etc.
Additional Comfort Features
Some stadium chairs for grandstands are basic and standard while others offer features that make the chair itself more comfortable.
Chairs with armrests and backing offer a more relaxed position than having to sit up with no support for either your back or arms.
Most of the time grandstand seating is made up of weather-resistant materials like metal, wood, or hard plastic.
In some cases, indoor seating may have cushioned and fabric seats to offer something a little more forgiving to sit in for long periods of time.
For grandstands that offer individual seating such as stadium chairs, they may come with amenities that will help store the items offered from concession stands.
This will often be a drink holder on the armrest or on the back of the seat in front of you.
Another great amenity is a tray for food that either folds out also from the armrest or from the back of the chair directly in front of you.
Going to see the event is no longer the whole show. This is why updating your grandstand stadium to fit modern tech is important.
This may include charging stations throughout the stadium or even offered at the seats.
For more expensive seats like premium sections or boxed seating more advanced technology features are encouraged to make the experience more exclusive.
This may include heated seating, audio inputs to hear commentary, and other features that smoothly integrate with today’s culture.
Additional Spaces Below The Infrastructure
There is a multitude of different design options for using the space below the seating section of a grandstand.
Normally, the section underneath will include concession stands and gift shops, locker rooms, gyms, meeting rooms, and more.
Restrooms for the public are usually one of the first things to be accounted for in the space below the seating.
This meets public safety guidelines and will offer on multiple levels close to the exit of seating.
These are in close proximity to the concessions stands as they are also scattered throughout the different levels.
A huge part of any grandstand is having concessions stands for food and drink options for the spectators.
Oftentimes there will be several different concession stands built into the permanent setup of grandstand seating.
Even in temporary grandstands concessions can be built under the structure if it opens underneath.
Another important feature that gets built-in is gift shops.
It’s an easy way for venue owners to make money and a convenient spot for the fans to find during an intermission or break from the spectacle.
These are often close to or next to the concession stands and have a similar space and structure.
For permanent grandstands, meeting rooms are an important part of the underneath structure.
There are really two types of meeting rooms that get put into place.
The first is for the executives and business people to meet about running the event, the financials, and so on.
This would include comfortable conference rooms that would be closed off to the public and most likely towards the top floor of a grandstand.
The second type of meeting room will be for the players/coaches if it’s a sporting venue.
Usually, this is where the athletes or teams will go over film and logistical stuff.
This room may have higher tech needs because of this.
Locker rooms are probably the first thing to be considered for grandstands.
This is a must as the athletes need somewhere to go before, during, and after the game.
The rooms will be much larger than other dedicated spaces because they normally include not only a lot of electrical work but also a lot of plumbing.
They have showers, ice baths, therapy rooms, bathrooms, and so many more features depending on how upscale the locker room is.
This is what is common for baseball but for horse tracks or race tracks for cars, the locker rooms may look a little different.
They may just be private rooms with all these features of a standard team locker room.
What Is The Quality And Durability Of Different Types Of Grandstands?
Grandstand quality and durability follow strict code as it is a slightly different seating setup than stadium-seating.
It really boils down to what type of materials you are using and the type of structure you are using. There are several to choose from.
Steel beams and steel columns have lifespans of 100-200 years depending on the manufacture and how it is galvanized.
Most are made of steel such as the following frames.
Angle Steel Frame:
This is one of the more economical and standard choices for venue owners, designers, and contractors.
The design setup allows for easy-install and durable cross-beams to support the entire structure.
This structure allows venues to add seats as their capacity grows because of how they are installed without losing any quality whatsoever.
In other words, a top row can be added at any time.
This may make one think that they can’t be very durable based on how flexible they are but that’s not true.
They are often made of aluminum and steel with the cross-beam structure providing strength and support in multiple areas under the structure.
Leg Truss Structure:
This is the kind of structure that sits between the angle steel frame and permanent solutions because the leg truss offers a slightly high seating capacity.
Even more cost-friendly than the angle steel frames this structure uses wide-flange stringers, steel angle columns, and bracing at six feet on center.
Typically made of steel for strength and support and often galvanized to prevent any sort of rusting from the weather.
Permanent I-Beam Structure:
These Permanent I-Beam Structures do not move once put in, meaning they will withstand much more abuse from possibly weather and definitely spectators.
The ratio of strength to product blows contractors out of the water and is why it is often the first choice for all grandstands.
It resembles and capital I gave its name with two beams angles horizontally and one become connecting the two through the middle.
The setup plays off any weaknesses steel beams may face (bowing in the center) making it one of the most durable and safe setups possible.
Figure 10 I Beam Steel Structure.
If there is individual seating for outdoor events it is often the HDPE material previously mentioned because of its fire and weather-resistant making it perfect for outdoor grandstand seating.
Depending on the maintenance quality HDPE can last 50 to 100 years without needing to be replaced from weather and erosion.
What Is The Spacing Measurements Between Rows And Aisles Of Grandstands?
Length of Bleacher Seat:
The bleacher seat itself is usually 18 inches which usually cannot take up much or any space of the length of individual rows because of safety reasons.
Length of Individual Rows:
Rows in grandstands with bleachers or elevated platforms with individual seating often leave 22 to 24 inches of room between rows.
The rise between the rows sloping upwards depends on the design needs and the sightline that is appropriate for spectators.
The average rise is around 9.5 inches per row.
This rise is the height difference between the base of the platform and the base of the next platform one row up.
For high-rise bleachers, you may find the base differences anywhere between 11 and 16 inches per row.
Some bleachers known as risers are adjustable and can change their height and sightline depending on the event.
This is usually some form of retractable seating allowing venues to choose how many rows they need and the spacing between rows.
Complying with safety codes typically a minimum of 36 inches or three feet is allowed per aisle for easy movement.
This offset the standard seat measurement by three times its size which should allow two people to pass comfortably moving in opposite directions.
Aisles may be slightly bigger if they offer a guardrail down the middle for spectators to hold onto.
This complies with guardrail safety fall codes.
Is There Any Spacing Between Seats In Grandstands?
Typically, there is little to no spacing between grandstand seats. If there are individual seats you may find two inches between the seats for spacing.
If this is a bleacher setup with no designated individual chairs then you will find no space as it is a continuous beam with first come first serve seating style.
Are Grandstands Accessible To Handicapped People?
Grandstands like stadiums are required to have accessible seating designated for handicapped people.
This is referred to as ADA seating and it follows the rules of The Americans With Disabilities Act.
This law states that equal opportunity must be provided to handicapped Americans at all events such as concerts, sports, presentations, and more where tickets are sold.
Four percent of the total number of seats must be accessible meeting all safety standards and guidelines.
This would require that handicapped seating be placed in areas that have easy exit and entry points.
The areas must also in close proximity to concession stands still following the equal opportunity rules.
Usually, there is a designated handicapped opportunity in each section so they have the same options as non-handicapped persons.
