The first elevator in the United States was installed at Harvard University in 1874. It was not a passenger elevator as we typically think of today, but rather a freight elevator used to move heavy items within a building. The installation of this elevator marked an important development in building technology and transportation within multi-story structures. It was based on the design of Elisha Otis, who is famous for inventing the safety elevator with a safety brake system that prevents the elevator from falling if the hoisting cable fails. Otis’ innovation played a pivotal role in making elevators safe and practical for everyday use, leading to their widespread adoption in buildings around the world.
Elevator design by the German engineer Konrad Kyeser (1405)
Education communities are stewards of 100’s of lifts, elevators and moving walks. At the University of Michigan, there are the better part of 1000 of them; with 19 of them in Michigan Stadium alone. The cost of building them — on the order of $50,000 to $150,000 per floor depending upon architectural styling — and the highly trained staff needed to operate, maintain and program interoperability software is another cost that requires attention. All building design and construction disciplines — architectural, mechanical and electrical have a hand in making this technology safe and sustainabile.
We start with international and nationally developed best practice literature and work our way to state level adaptations. Labor for this technology is heavily regulated.
Its a rarefied and crazy domain for the user-interest. Expertise is passionate about safety and idiosyncratic but needs to be given the life safety hazard. Today we review o pull together public consultation notices on relevant codes, standards and regulations today 11 AM/EDT.
At the 1853 New York World’s Fair Elisha Otis amazed a crowd when he ordered the only rope holding the platform on which he was standing cut by an axeman. The platform fell only a few inches before coming to a halt; thus proving the safety locking mechanism he had invented will work. These elevators quickly became the type in most common usage and made vertical living possible.
Most large research universities have 100 – 1000 elevators that are highly regulated, maintained by highly regulated service personnel and inspected by highly trained conformance operatives; thus our primary interest in state-specific regulations. We have a secondary interest in innovation in the technology generally. Many sustainability goals urged in academic circles — which include greater population density in smaller areas — are challenged by mobility issues.
From the project prospectus:
“…The main feature of these products is that they are an integral part of industrial, residential or public buildings. Consequently, they should be adaptable to the technical and architectural constraints of such buildings. They must also meet the capacity requirements imposed by the intended use of the building. These products are considered as means of transport and therefore represent an essential component of the functional life of the buildings in which they are installed. Contrary to most public means of transport, they are intended for free use and operation by their passengers, which makes the integration of safety an essential concern…”
We maintain the work products of this committee on the standing agendas of our Mechanical, Elevator and Global colloquia; open to everyone. See our CALENDAR for the next online meeting.
Michigan Stadium — the largest collegiate stadium in the world — has 19 elevators.
Any multi-story building requires inspection and maintenance of structural steel framework. The steel supports the building’s weight and resists environmental forces like wind and seismic activity. Over time, corrosion, fatigue cracks, or connection failures can weaken the structure, risking collapse. Inspections detect these issues early, while maintenance, like repainting or replacing damaged parts, preserves steel integrity. For student housing, occupant safety is critical, and compliance with building codes reduces liability risks. Neglecting these practices can lead to structural failure, endangering residents and causing costly repairs or legal issues. Regular upkeep ensures safe, long-lasting buildings.
During today’s session we examine the relevant standards with proposed revisions open for public comment. Use the login credentials at the upper right of our home page.
No single universal code or standard guarantees that buildings will never crack or fail structurally, as structural integrity depends on various factors like design, materials, construction quality, environmental conditions, and maintenance. However, several widely adopted codes and standards aim to minimize the risk of structural failure and ensure safety, durability, and serviceability. These provide guidelines for design, construction, and maintenance to prevent issues like cracking or catastrophic failure.
φ
Key Codes and Standards:
International Building Code (IBC): Widely used in the United States and other regions, the IBC sets minimum requirements for structural design, materials, and maintenance to ensure safety and performance. It references standards like ASCE 7 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) for load calculations (e.g., wind, seismic, snow).Maintenance provisions require regular inspections and repairs to address issues like cracking or deterioration.
ACI 318 (Building Code Requirements for Structural Concrete): Published by the American Concrete Institute this standard governs the design and construction of concrete structures.Includes requirements to control cracking (e.g., reinforcement detailing, concrete mix design) and ensure durability under environmental exposure.Maintenance guidelines recommend periodic inspections for cracks, spalling, or reinforcement corrosion.
AISC 360 (Specification for Structural Steel Buildings): Published by the American Institute of Steel Construction, this standard covers the design, fabrication, and erection of steel structures. Addresses fatigue, connection design, and corrosion protection to prevent structural failure. Maintenance involves inspecting for issues like weld imperfections or coating degradation.
Elevator, escalator and moving walk systems are among the most complicated systems in any urban environment, no less so than on the #WiseCampus in which many large research universities have 100 to 1000 elevators to safely and economically operate, service and continuously commission. These systems are regulated heavily at state and local levels of government and have oversight from volunteers that are passionate about their work.
These “movement systems” are absorbed into the Internet of Things transformation. Lately we have tried to keep pace with the expansion of requirements to include software integration professionals to coordinate the interoperability of elevators, lifts and escalators with building automation systems for fire safety, indoor air quality and disaster management. Much of work requires understanding of the local adaptations of national building codes.
Some university elevator O&M units use a combination of in-house, manufacturer and standing order contractors to accomplish their safety and sustainability objectives.
In the United States the American Society of Mechanical Engineers is the dominant standards developer of elevator and escalator system best practice titles; its breakdown of technical committees listed in the link below:
As always, we encourage facility managers, elevator shop personnel to participate directly in the ASME Codes & Standards development process. For example, it would be relatively easy for our colleagues in the Phoenix, Arizona region to attend one or more of the technical committee meetings; ideally with operating data and a solid proposal for improving the A17 suite.
All ASME standards are on the agenda of our Mechanical, Pathway and Elevator & Lift colloquia. See our CALENDAR for the next online teleconferences; open to everyone. Use the login credentials at the upper right of our home page.

The earliest installation of a passenger elevator in a university building in the United States was at the Massachusetts Institute of Technology in Cambridge. In 1861, Otis Brothers & Co., the company founded by Elisha Graves Otis, installed the first passenger elevator in this three-story structure that housed laboratories, classrooms, and offices for faculty and students.
This early installation of a passenger elevator marked an important milestone in the history of vertical transportation on college and university campuses, and it paved the way for the adoption of elevators in other educational institutions as they expanded in size and height over time.

Water is essential for sanitation and hygiene — and proper sanitation is essential for protecting water sources from contamination and ensuring access to safe drinking water. Access to safe water and sanitation is crucial for preventing the spread of waterborne diseases, which can be transmitted through contaminated water sources or poor sanitation practices. Lack of access to safe water and sanitation can lead to a range of health problems, including diarrheal diseases, cholera, typhoid, and hepatitis A.
On the other hand, poor sanitation practices, such as open defecation, can contaminate water sources, making them unsafe for drinking, bathing, or cooking. This contamination can lead to the spread of diseases and illness, particularly in developing countries where access to clean water and sanitation facilities may be limited.
We track the catalog of the following ANSI accredited standards developers that necessarily require mastery of building premise water systems:
American Society of Heating, Refrigerating and Air-Conditioning Engineers: ASHRAE develops standards related to heating, ventilation, air conditioning, refrigeration systems — and more recently, standards that claim jurisdiction over building sites.
American Society of Mechanical Engineers: ASME develops standards related to boilers, pressure vessels, and piping systems.
American Water Works Association: AWWA is a standards development organization that publishes a wide range of standards related to water supply, treatment, distribution, and storage.
ASTM International: ASTM develops and publishes voluntary consensus standards for various industries, including water-related standards. They cover topics such as water quality, water sampling, and water treatment.
National Fire Protection Association: NFPA develops fire safety standards, and some of their standards are related to water, such as those covering fire sprinkler systems and water supplies for firefighting within and outside buildings. We deal with the specific problems of sprinkler water system safety during our Prometheus colloquia.
National Sanitation Foundation International (NSF International): NSF International develops standards and conducts testing and certification for various products related to public health and safety, including standards for water treatment systems and products.
Underwriters Laboratories (UL): UL is a safety consulting and certification company that develops standards for various industries. They have standards related to water treatment systems, plumbing products, and fire protection systems.

* The evolution of building interior water systems has undergone significant changes over time to meet the evolving needs of society. Initially, water systems were rudimentary, primarily consisting of manually operated pumps and gravity-fed distribution systems. Water was manually fetched from wells or nearby sources, and indoor plumbing was virtually nonexistent.
The Industrial Revolution brought advancements in plumbing technology. The introduction of pressurized water systems and cast-iron pipes allowed for the centralized distribution of water within buildings. Separate pipes for hot and cold water became common, enabling more convenient access to water for various purposes. Additionally, the development of flush toilets and sewage systems improved sanitation and hygiene standards.
In the mid-20th century, the advent of plastic pipes, such as PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride), revolutionized plumbing systems. These pipes offered durability, flexibility, and ease of installation, allowing for faster and more cost-effective construction.
The latter part of the 20th century witnessed a growing focus on water conservation and environmental sustainability. Low-flow fixtures, such as toilets, faucets, and showerheads, were introduced to reduce water consumption without compromising functionality. Greywater recycling systems emerged, allowing the reuse of water from sinks, showers, and laundry for non-potable purposes like irrigation.
With the advancement of digital technology, smart water systems have emerged in recent years. These systems integrate sensors, meters, and automated controls to monitor and manage water usage, detect leaks, and optimize water distribution within buildings. Smart technologies provide real-time data, enabling better water management, energy efficiency, and cost savings.
The future of building interior water systems is likely to focus on further improving efficiency, sustainability, and water quality. Innovations may include enhanced water purification techniques, decentralized water treatment systems, and increased integration of smart technologies to create more intelligent and sustainable water systems.
The first mover in building interior water supply systems can be traced back to the ancient civilizations of Mesopotamia, Egypt, and the Indus Valley. However, one of the earliest known examples of sophisticated indoor plumbing systems can be attributed to the ancient Romans.
The Romans were pioneers in constructing elaborate water supply and distribution networks within their cities. They developed aqueducts to transport water from distant sources to urban centers, allowing for a centralized water supply. The water was then distributed through a network of lead or clay pipes to public fountains, baths, and private residences.
One notable example of Roman plumbing ingenuity is the city of Pompeii, which was buried by the eruption of Mount Vesuvius in 79 AD. The excavation of Pompeii revealed a well-preserved plumbing system that included indoor plumbing in some houses. These systems featured piped water, private bathrooms with flushing toilets, and even hot and cold water systems.
The Romans also invented the concept of the cloaca maxima, an ancient sewer system that collected and transported wastewater away from the city to nearby bodies of water. This early recognition of the importance of sanitation and wastewater management was a significant advancement in public health.
While the Romans were not the only ancient civilization to develop indoor plumbing systems, their engineering prowess and widespread implementation of water supply and sanitation infrastructure make them a key player in the history of building interior water systems.
These square, spiraled buns originated in early 18th-century London at the Chelsea Bun House, a royal-favored spot selling spiced, fruit-filled yeast buns to Georgian nobility. They cut a foodway path across Britain as an indulgent treat, settling at “Fitzbillies Bakery” on Trumpington Street eventually making first landfall in North America at Penn State University as “Grilled Stickies”.
