The MIL-SPEC catalog and its evolution have had a significant impact on various industries beyond the military sector. Many civilian industries have adopted military standards as a benchmark for quality, reliability, and compatibility in their products and processes.

World War II Era:

The MIL-SPEC system traces its roots back to the World War II era when the U.S. military faced challenges in coordinating manufacturing efforts across multiple suppliers.  To address these challenges, the military began developing specifications and standards that detailed the requirements for various equipment and materials, including dimensions, materials, performance criteria, and testing procedures.

Post-World War II:

After World War II, the MIL-SPEC catalog expanded significantly to cover a wide range of military equipment, ranging from electronics and aircraft components to clothing and food supplies.  The standards were continuously updated and revised based on technological advancements, lessons learned, and evolving military needs.

Evolution into MIL-STD:

In the 1950s and 1960s, the MIL-SPEC system evolved into the Military Standard (MIL-STD) system to provide even more comprehensive and detailed specifications.  MIL-STD documents incorporated a broader scope of requirements, including design criteria, quality control processes, and test methodologies.  The MIL-STD system aimed to ensure consistent design and manufacturing practices across contractors and suppliers.

MIL-STD Transition to Commercial Standards:

Over time, the reliance on MIL-STDs started to decline, and there was a shift towards adopting commercial standards whenever possible.  This transition allowed the military to benefit from the advancements and cost efficiencies of commercial technologies.  However, certain critical military-specific standards, such as those related to security and specialized equipment, continued to be maintained within the MIL-STD framework.

DoD’s Transition to Performance-Based Specifications:

In recent years, the DoD has been moving away from prescriptive specifications (MIL-STDs) towards performance-based specifications. Performance-based specifications focus on defining the desired outcomes and performance requirements while allowing contractors greater flexibility in meeting those requirements. This approach encourages innovation, cost-effectiveness, and broader industry participation in military contracts.

Campus Rail Transit

The West Virginia University PRT (Personal Rapid Transit) system is a unique and innovative form of public transportation that serves the WVU campus and the city of Morgantown, West Virginia. The PRT system consists of a series of automated, driverless vehicles that operate on an elevated track network, providing fast and convenient transportation to key destinations on and around the WVU campus.

The PRT system was first developed in the 1970s as a solution to the growing traffic congestion and parking demand on the WVU campus. The system was designed to be efficient, reliable, and environmentally friendly, and to provide a high-tech, futuristic mode of transportation that would appeal to students and visitors.

The PRT system currently operates five different stations, with stops at key campus locations such as the Mountainlair Student Union, the Engineering Research Building, and the Health Sciences Center. The system is free for all WVU students, faculty, and staff, and also offers a low-cost fare for members of the general public.

The PRT system has been recognized as one of the most advanced and innovative public transportation systems in the world, and has won numerous awards for its design, efficiency, and environmental sustainability. It has also become an iconic symbol of the WVU campus, and is often featured in promotional materials and advertising campaigns for the university.

Performance Monitoring for Power Plants

“A View of Murton Colliery near Seaham, County Durham” (1843) / John Wilson Carmichael

The American Society of Mechanical Engineers (ASME) has registered a Project Initiation Notification with ANSI to launch a revision to its consensus product ASME PM-202x, Performance Monitoring for Power Plants.  This product should interest stakeholders in involved in college and universities with district energy plants — facility management staffs, consulting engineers, operations and maintenance staff.

From the project prospectus:

These Guidelines cover fossil-fueled power plants, gas-turbine power plants operating in combined cycle, and a balance-of-plant portion including interface with the steam supply system of nuclear power plants.  They include performance monitoring concepts, a description of various methods available, and means for evaluating particular applications.

Since the original publication of these Guidelines in 1993—then limited to steam power plants—the field of performance monitoring (PM) has gained considerable importance.  The lifetime of plant equipment has been improved, while economic demands have increased to extend it even further by careful monitoring.  The PM techniques themselves have also been transformed, largely by the emergence of electronic data acquisition as the dominant method of obtaining the necessary information.

These Guidelines present:

• “Fundamental Considerations”—of PM essentials prior to the actual application, so you enter fully appraised of all the requirements, potential benefits and likelihood of tradeoffs of the PM program. 

• “Program Implementation”—where the concepts of PM implementation, diagnostics and cycle interrelationships have been brought into closer conjunction, bringing you up-to-date with contemporary practice.

• “Case Studies / Diagnostic Examples”—from the large amount of experience and historical data that has been accumulated since 1993.

Intended for employees of power plants and engineers involved with all aspects of power production.

From ANSI’s PINS registry:

Project Need: This document is being developed in order to address performance monitoring and optimization techniques for different power generating facilities. The latest trends and initiatives in performance monitoring as well as practical case studies and examples will be incorporated.

Stakeholders: Designers, producers/manufacturers, owners, operators, consultants, users, general interest, laboratories, regulatory/government, and distributors.

This document will cover power generation facilities including steam generators, steam turbines, and steam turbine cycles (including balance of plant of nuclear facilities), gas turbines, and combined cycles. The guidelines include performance monitoring concepts, a description of various methods available, and means for evaluating particular applications.

No drafts open for public consultation at this time.   The PINS announcement was placed on October 11th*.   The PINS registry is a stakeholder mapping platform that identifies the beginning of a formal process that may interest other accredited, competitor standards developers.   Many ASME consensus products may be indirectly referenced in design guidelines and construction contracts with the statement “Conform to all applicable codes”

The landing page for the ASME standards development enterprise is linked below:

ASME C&S Connect

Note that you will need to set up a (free) account to access this and other ASME best practice titles.

We maintain all ASME consensus products on the standing agenda of our periodic Mechanical and Energy teleconferences.   See our CALENDAR for the next online meeting; open to everyone.

We break down our coverage of laboratory safety and sustainability standards thus:

Laboratories 100 covers a broad overview of the safety and sustainability standards setting catalogs; emphasis on titles incorporated by reference into public safety laws.

Laboratories 200 covers laboratory occupancies primarily for teaching

Laboratories 300 covers laboratories in healthcare clinical delivery.

Laboratories 400 covers laboratories for scientific research; long since creating the field of environmental health and safety in higher education and a language (and acronyms of its own: CSHEMA)

In the most recent fiscal year, the National Institutes of Health had a budget of approximately $47.7 billion. A substantial portion of this budget is allocated to research at colleges and universities. Specifically, about 83% of NIH’s funding, which translates to roughly $39.6 billion, is awarded for extramural research. This funding is distributed through nearly 50,000 competitive grants to more than 2,500 universities, medical schools, and other research institutions across the United States​

The cost to build a “standard” classroom runs about $150 to $400 per square foot; a scientific research laboratory about $400 to $1200 per square foot.

Laboratories 500 is broken out as a separate but related topic and will cover conformity and case studies that resulted in litigation.  Both Laboratories 200 and 400 will refer to the cases but not given a separate colloquium unless needed.

Today we break down action in the literature governing the safety and sustainability of instruction and research laboratories in the United States specifically; but also with sensitivity to similar enterprises in research universities elsewhere in the world.  “Everyone” has an iron in this fire:

International Building Code Chapter 38: Higher Education Laboratories

ASCE Structural Engineering Institute (so that the foundations and “bone structure” of laboratories survive earthquakes, floods and other Force majeure mayhem)

National Electrical Code Chapter 5: Special Occupancies

ASHRAE Laboratory Design Guide

NFPA 45  Standard on Fire Protection for Laboratories Using Chemicals

IEEE Electrical Safety in Academic Laboratories

…and ISEA, AWWA, AIHA, BIFMA, CLSI, LIA, IAPMO, NSF, UL etc. among ANSI accredited standards developing organizations…

..and addition to NIST, Federal code of Regulations Title 29, NIH, CDC, FEMA, OSHA etc

…and state level public health regulations; some of them adapted from OSHA safety plans

Classroom and offices are far simpler.  Laboratories are technically complicated and sensitive area of concern for education communities not only responsible for the safety of instructional laboratories but also global communities with faculty and staff that must simultaneously collaborate and compete.  We have been tip-toeing through the technical and political minefields for nearly 20 years now and have had some modest success that contributes to higher safety and lower costs for the US education community.

Design Considerations for Hot Water Plumbing

Baseline Standards for Student Housing

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

Indoor plumbing has a long history, but it became widely available in the 19th and early 20th centuries. In the United States, for example, the first indoor plumbing system was installed in the Governor’s Palace in Williamsburg, Virginia in the early 18th century. However, it was not until the mid-19th century that indoor plumbing became more common in middle-class homes.

One important milestone was the development of cast iron pipes in the 19th century, which made it easier to transport water and waste throughout a building. The introduction of the flush toilet in the mid-19th century also played a significant role in making indoor plumbing more practical and sanitary.

By the early 20th century, indoor plumbing had become a standard feature in most middle-class homes in the United States and other developed countries. However, it was still not widely available in rural areas and poorer urban neighborhoods until much later.
