MEP Design in Sports: Proper Lighting is Essential
It is no secret that Americans are consuming sports entertainment more than ever before causing live sports television markets to skyrocket. With every grant of rights agreement reached, with every broadcasting bid won, the payouts continue to climb at alarming rates for all major sports. So does the pressure to perfectly present these programs.
The staffs of major television networks work painstaking hours to deliver a sublime viewing experience for the audience at home. While these production professionals have plenty of nifty Hollywood camera tricks up their sleeves, if the venue is not up to par, all of their efforts are for naught.
What is the Most Important Component to Sport Facilities? Proper stadium infrastructure has the ability to enable the absolute best for athletic competition broadcasting and one of the most basic, yet most under appreciated aspects in the initial design phase for these venues, is lighting. (more…)
Deflection Issues for Operable Partitions
Operable partitions provide versatility to room layouts. They provide sound separation and aesthetic value. But to a structural engineer, the devil is in the details. These systems must be able to function properly in order to maintain operability and sound retention.
The support of these systems must not only carry the partition weight but also limit the deflection for proper operation. The simplest approach is to place a floor supported system on a slab-on-grade. But this type of system is rarely specified.
All structures deflect. It is an indication of the elastic properties of the affected member or members. Although easier to accommodate in new structures, adding these systems to existing buildings can be problematic.
Different panel systems possess different deflection requirements. The most common system is the folding partition. Their construction depends on the STC rating (sound transmission class) which affects the deflection limitations. Other systems include accordion doors, movable glass panels, self-supporting panels and portable panels. For this article, we will address the needs of the folding panel partitions.

The role of an Engineer of Record (E.O.R.) on a commercial Design-Bid–Build Project is well defined. But when it comes to Fast Track and smaller building projects this is not always the case.
In the interest of “cost savings” and schedule the involvement of the E.O.R. becomes somewhat less defined. At times, too much reliance is placed on the Specialty or Component Engineer by the Owner or Contractor.
