Baseball Lighting

“Baseball at Night” | Morris Kantor (1934)

 

 

 

“Baseball is ninety percent mental

and the other half is physical.”

– Yogi Berra

 

After athletic facility life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

 

During the spring baseball season the document linked below provides guidance for illumination designers, contractors and facility managers:

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We cover the objectives of the energy conservation advocates in separate posts; notably advocates using the International Code Council and the ASHRAE suite to advance their agenda to press boxes and the entire baseball experience (interior and exterior) site in separate posts.

We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next Sport colloquium.   We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

Water Safety & Sustainability

The American Water Works Association is one of the first names in accredited standards developers that administer leading practice discovery in backflow prevention consensus documents; usually referenced in local and state building codes; and also in education facility design guidelines and construction specifications.

The original University of Michigan standards enterprise gave highest priority to backflow standards because of their central importance of backflow management to education communities; especially large research universities nested within a municipal water system.  Backflow prevention; an unseen technology that assures a safe drinking water supply by keeping water running in one direction by maintaining pressure differences.  Analogous to the way we want electrical current to run in one direction, failure of backflow prevention technology poses a near-instantaneous health risk for the contamination of potable water supplies with foul water.  In the most obvious case, a toilet flush cistern and its water supply must be isolated from the toilet bowl.  In a less obvious case, but at greater scale, a damaged backflow prevention technology at a university research building can contaminate an host-community potable water supply.

There are other ANSI accredited standards developers in the backflow prevention technology space — the International Code Council, the IAPMO Group and ASSE International — for example.

Steeplechase Water Jump

The steeplechase event requires a combination of speed, endurance, and jumping ability, as athletes must clear the barriers while maintaining their pace and negotiating the water jump. The rules and specifications for the steeplechase event are set by the International Association of Athletics Federations the governing body for the sport of athletics (track and field) worldwide; with minor adaptations by the NCAA for intercollegiate competition.

Emma Coburn | University of Colorado Boulder

The steeplechase is a distance race with barriers and a water pit that athletes must clear during the race.  According to the NCAA Track and Field and Cross Country rulebook, the standards for the steeplechase water jump are as follows:

  1. Length: The water pit must be at least 3.66 meters (12 feet) long.
  2. Width: The water pit must be at least 3.66 meters (12 feet) wide.
  3. Depth: The water pit must have a minimum depth of 0.7 meters (2 feet 4 inches) and a maximum depth of 0.9 meters (2 feet 11 inches).
  4. Slope: The slope of the water pit must not exceed 1:5, meaning that for every 5 meters in length, the water pit can rise by no more than 1 meter in height.
  5. Barrier: The water pit must be preceded by a solid barrier that is 91.4 cm (3 feet) high. Athletes are required to clear this barrier before landing in the water pit.

These standards may be subject to change and may vary depending on the specific NCAA division (Division I, Division II, or Division III) and other factors such as venue requirements. Therefore, it’s always best to refer to the official NCAA rules and regulations for the most up-to-date and accurate information on the steeplechase water jump standards in NCAA competitions.

ASTM F 2157-09 (2018) Standard Specification for Synthetic Surfaced Running Tracks
This specification establishes the minimum performance requirements and classification when tested in accordance with the procedures outlined within this specification. All documents referencing this specification must include classification required.

ASTM F 2569-11 Standard Test Method for Evaluating the Force Reduction Properties of Surfaces for Athletic Use
This test method covers the quantitative measurement and normalization of impact forces generated through a mechanical impact test on an athletic surface. The impact forces simulated in this test method are intended to represent those produced by lower extremities of an athlete during landing events on sport or athletic surfaces.

ASTM F 2949-12 Standard Specification for Pole Vault Box Collars
This specification covers minimum requirements of size, physical characteristics of materials, standard testing procedures, labeling and identification of pole vault box collars.

“The Boys in the Boat”

The Boys in the Boat is a true story based on the struggles and sacrifices made by the University of Washington rowing team to compete at rowing at the 1936 Summer Olympics – Men’s eight.

Joseph Sutton-Holcomb from The Seattle Times writes that author Daniel James Brown got the idea to write this book when his neighbor Judy Willman said that her father, Joe Rantz, was a fan of his works and wanted to have a conversation with the author. That conversation with Joe Rantz about life during the Great Depression led to an in-depth chat about his time as a rower at the University of Washington.

Recreational sports, athletic competition, and the facilities that support it, are one of the most visible activities in any school, college or university in any nation.  Arguably, these activities resemble religious belief and practice.   Enterprises of this kind have the same ambition for safety and sustainability at the same scale as the academic and healthcare enterprises.  

According to IBISWorld Market Research, Sports Stadium Construction was a $6.1 billion market in 2014, Athletic & Sporting Goods Manufacturing was a $9.2 billion market in 2015, with participation in sports increasing 19.3 percent by 2019 — much of that originating in school, college and university sports and recreation programs.  We refer you to more up to date information in the link below:

Sports & Athletic Field Construction Industry in the US – Market Research Report

Today at the usual time we will update our understanding of the physical support systems for the track and field activity listed below:

  1. Sprinting: Races over short distances, typically 100m, 200m, and 400m.
  2. Middle-distance running: Races covering distances between sprinting and long-distance running, such as 800m and 1500m.
  3. Long-distance running: Races over longer distances, including 3000m, 5000m, 10,000m, and marathons.
  4. Hurdling: Races where athletes jump over hurdles at set distances, such as 110m hurdles (for men) and 100m hurdles (for women).
  5. Steeplechase: A long-distance race that includes hurdles and a water jump.
  6. Racewalking: A form of walking competition where athletes race over various distances while maintaining contact with the ground.
  7. Relays: Team races where athletes take turns running a specified distance before passing a baton to the next runner. Common relay distances include 4x100m and 4x400m.
  8. High jump: Athletes attempt to jump over a horizontal bar placed at measured heights without knocking it down.
  9. Pole vault: Athletes use a pole to vault themselves over a high bar.
  10. Long jump: Athletes sprint down a runway and jump as far as possible into a sandpit.
  11. Triple jump: Athletes perform a hop, step, and jump sequence into a sandpit, with distances measured from the takeoff board to the nearest mark made in the sand by any part of the body.
  12. Shot put: Athletes throw a heavy metal ball for distance.
  13. Discus throw: Athletes throw a discus, a heavy circular object, for distance.
  14. Javelin throw: Athletes throw a javelin, a spear-like object, for distance.
  15. Hammer throw: Athletes throw a heavy metal ball attached to a wire and handle for distance.
  16. Decathlon (men) / Heptathlon (women): Multi-event competitions where athletes compete in ten (decathlon) or seven (heptathlon) different track and field events, with points awarded for performance in each event.

Audio Standards

“A Dance to the Music of Time” 1640 Nicolas Poussin

 

 

“The voice of the intellect is a soft one,

but it does not rest until it has gained a hearing.”

— Sigmund Freud

 

The education industry provides a large market for occupancy classes — athletic stadiums, student assembly spaces, performance theaters, large lecture halls– that depend upon effective audio systems*.   To an unexpected degree the structural engineering, specification of materials and electrical system design and operation is informed by acoustical considerations.  So does the integration of fire safety and mass notification systems into normal state enterprises so it is wise to follow and, ideally, participate in leading practice discovery and promulgation of audio standards.

The Audio Engineering Society — one of the first names in this space — has a due process platform that welcomes public participation.   All of its standards open for public comment completed their revision cycle mid-November as can be seen on its standards development landing page below:

AES Standards Development

Note that AES permits access to those revision even after the comment deadline.  You are encouraged to communicate directly with the Direct communication with the standards staff at Audio Engineering Society International Headquarters, 551 Fifth Avenue, Suite 1225, New York NY 10176,  Tel: +1 212 661 8528

We keep the AES suite on the standing agenda of our periodic Lively Arts teleconference.  See our CALENDAR for the next online meeting.

This facility class is one of most complex occupancy classes in education facilities industry so we also collaborate with experts active in the IEEE Education & Healthcare Facilities Committee. Much of the AES suite references, and borrows from, International Electrotechnical Commission system integration and interoperability standards.   The IEEE E&H committee meets online again four times monthly in European and American time zones.  The meeting dates are available on the IEEE E&H website
