Exploring complex hotels, resorts, and casinos: Codes and standards

Casinos and resorts are designed for fun and relaxation, but with such projects becoming increasingly complex and high-tech, engineers charged with tackling these structures have challenging work ahead of them in regards to complying with codes and standards.

CityCenter, located in Las Vegas, is a mixed-used development totaling 17 million sq ft stretching out over six high-rise towers. Courtesy: JENSEN HUGHESCSE: Please explain some of the codes, standards, and guidelines you commonly use during the design process. Which codes/standards should engineers be most aware of?

Grove: The majority of the United States uses various editions of the family of codes developed by the International Code Council (ICC). These include the International Building Code (IBC), International Fire Code (IFC), International Mechanical Code (IMC), International Plumbing Code (IPC), etc. The IBC and IFC reference a wide variety of standards developed by different organizations, such as the NFPA, ASTM International, American National Standards Institute (ANSI), etc. For example, NFPA has various fire and life safety installation standards, such as NFPA 13: Standard for the Installation of Sprinkler Systems, NFPA 72: National Fire Alarm and Signaling Code, NFPA 14: Standard for the Installation of Standpipe and Hose Systems, and NFPA 20: Standard for the Installation of Stationary Pumps for Fire Protection, to name a few.

Regan: The IBC is the primary code, followed by  NFPA 101: Life Safety Code and NFPA 70: National Electrical Code. Most recent designs have included a resiliency requirement as set forth by the National Infrastructure Advisory Council in 2009. This requirement is most often seen in coastal and Caribbean locations that have experienced massive natural disasters warranting the requirement. LEED certification is a requirement in nearly all domestic and offshore requests.

CityCenter features include a 2,000-seat theater, a 150,000-sq-ft casino, an ultra-high-end retail and entertainment district, an underground parking garage, and a convention center. Courtesy: JENSEN HUGHESWhite: The IBC is the main code in the United States. Users need to be aware of the specific edition adopted in their particular jurisdiction, as well as any and all amendments to the IBC. Many additional codes and standards are referenced directly in the IBC and form an integral part of the overall governing code. NFPA standards are commonly adopted in part or in whole to supplement the IBC requirements. Furthermore, ANSI, ASTM, and the American Society of Mechanical Engineers (ASME) are commonly recognized testing authorities that govern quality and compliance of products of construction.

Dolan: Current codes include the 2012 IBC and associated mechanical/plumbing (IMC and IPC) and energy codes (International Energy Conservation Code (IECC), Uniform Mechanical Code (UMC), Uniform Plumbing Code (UPC), ASME 17.1: Safety Code for Elevators and Escalators , ASHRAE 62.1: Ventilation for Acceptable Indoor Air Quality, and ASHRAE 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings. The mechanical and plumbing codes generally alternate between the Uniform or International codes depending on the AHJ, unless a specific state code has been adopted. For projects in other countries, such as Macau, we typically use the International codes (IBC, IMC, and IPC) with the addition of local requirements where applicable, such as in life safety systems or building construction with refuge floors. Related NFPA sections are also used as part of the above codes, including 90A/B, 92, and 101.

Shino: The most common codes for fire protection engineers is the IBC and IFC, which also typically adopt NFPA guidelines for installation of fire protection and life safety. Typically, the IBC and IFC define when specific systems are required and the NFPA standards describe how to install the systems.

CSE: What are some best practices to ensure that such buildings meet and exceed codes and standards?

White: Developing a comprehensive fire and life safety strategy for the project is an important first step. Some jurisdictions, such as Clark County in Nevada, require a fire protection report to be stamped by a registered fire protection engineer. In jurisdictions where this isn’t mandatory, most clients voluntarily require it to clearly inform the entire design team of the building’s approach to code compliance. In buildings as complex as fully integrated resorts, it is a logical first step to ensure all consultants and designers are meeting code and designing toward a common solution. Exceeding code is often an owner-driven decision, whether to meet their corporate level of safety or to satisfy a particular underwriter. The fire and life safety strategy report would document such enhancements and become a contract document that is followed by the building and system designers. Traditionally, where specific directions to exceed code is not written into the contract documents, designers would not normally exceed code minimum as this incurs costs and possibly increased complexity.

CityCenter features include a 2,000-seat theater, a 150,000-sq-ft casino, an ultra-high-end retail and entertainment district, an underground parking garage, and a convention center. Courtesy: JENSEN HUGHESShino: Probably the most important thing to consider is staying ahead of the curve by participating, or at least following, the codes and standards development process. Knowing what AHJs around the country and world are facing in terms of code enforcement, helps shape how codes are developed. New building technologies, such as cross-laminated timber building materials, are advancing the construction industry, but codes and standards must keep up to make sure building occupants and first responders stay safe.

Grove: Designers and engineers need to be aware of the applicable codes and standards at the outset of the project, along with local amendments and guidelines. Having team members with experience in the applicable jurisdiction tends to ease the design and permitting process as well. Designers and engineers for these large projects need to be able to interpret the codes and standards properly and have the creativity to develop various means of meeting the intent of these requirements.

Regan: Design teams are constantly updated on the latest code practices and each branded hotel’s special design measures. This information is kept in a design package for a specified hotel/casino project.

CSE: How are codes, standards, or guidelines for energy efficiency impacting the design of such buildings?

Shino: From a fire protection engineering/life safety standpoint, energy efficiency has not been significantly impacted. However, because our business includes multiple disciplines, we definitely know that the last few code cycles have become more energy-focused. A project that was permitted under the 2009 IBC would have to go through a new energy evaluation to confirm compliance with the 2015 or 2018 IECC.

Regan: The impact of energy efficiency guidelines demands better and more finite engineering, which ultimately makes the project better. When energy efficiency fights resiliency, then steps are taken such that conflicting resiliency requests are in the background and not part of daily use, so their usage in a time of crisis is the only time that energy efficiency is affected.
