The American Association of State Highway and Transportation Officials is a standards setting body which publishes specifications, test protocols, and guidelines that are used in highway design and construction throughout the United States. Despite its name, the association represents not only highways but air, rail, water, and public transportation as well. Its technical committees are responsible for route numbering recommendations.
Although AASHTO sets transportation standards and policy for the United States as a whole, AASHTO is not an agency of the federal government; rather it is an organization of the states themselves. Policies of AASHTO are not federal laws or policies, but rather are ways to coordinate state laws and policies in the field of transportation.
One of its consensus products — the so-called “Green Book” — is heavily referenced in campus design guidelines and construction contracts because most education communities exist within municipal infrastructure. Power, water supply, sewers to schools and campuses large and small all tend to follow transportation pathways. The Green Book is revised periodically, the 2018 Edition the most recent.
We do not advocate in this product at the moment but follow the movement in concepts relevant to education communities; notably the recent reorganization that emphasizes transportation of people, rather than focusing primarily on moving vehicles. A new chapter discusses multimodal level of service and puts greater emphasis on lower-speed, walkable, urban zones in which new mobility technologies are emerging (such as micro-scooters on campuses)
We maintain the AASHTO catalog on our Pathways, Zoning and Mobility colloquia. See our CALENDAR for the next online meeting, open to everyone.
Founded in 1904 in Farmington Hills, Michigan, the ACI has the most widely adopted catalog of consensus-based standards for design, construction, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best use of concrete — the most widely used construction material in the world.
Q. How is brickwork different from masonry? A. Brickwork and masonry are related terms in construction, but they are not exactly the same.
Masonry refers to the broader practice of building structures using a variety of materials like stone, brick, concrete blocks, or tiles. It encompasses all forms of stonework, brickwork, and blockwork. Masonry is a general term for the craft and the materials used in creating walls, structures, and even decorative elements in construction.
Brickwork, on the other hand, is a specific subset of masonry that involves the use of bricks as the building material. It focuses solely on the techniques and practices of laying bricks to build walls, arches, and other structural or decorative elements.
While all brickwork is masonry, not all masonry is brickwork. Masonry can also involve stone or other materials, whereas brickwork is specifically about bricks.
Q. What is the difference between cement and concrete? A. Cement and concrete are two different materials, although they are often used together in construction projects. Cement is a powdery substance that is used as a binder in building materials, while concrete is a composite material made up of cement, water, and aggregates (such as sand, gravel, or crushed stone).
Cement is produced by grinding clinker (a mixture of raw materials such as limestone, clay, and iron ore) with gypsum and other additives, to produce a fine powder. This powder is then mixed with water to create a paste that can be used to bind building materials together, such as bricks or blocks, or to create mortars and grouts for masonry work.
Concrete, on the other hand, is a mixture of cement, water, and aggregates. The aggregates are typically added to provide strength and bulk to the concrete. The type and size of aggregates used can vary depending on the desired strength, texture, and other properties of the concrete.
Q. What skill standards are required of certified practitioners? A. Concrete work requires knowledge of materials, tools, techniques, safety practices, and local building codes. The specific skill standards may vary depending on the scope and complexity of the concrete work, as well as the location and applicable regulations. Some of the common skills and knowledge required for managing or installing concrete include:
Knowledge of materials: Understanding the properties of cement, aggregates, admixtures, and other materials used in concrete, as well as their interactions and effects on the final product.
Ability to read plans and specifications: Being able to interpret blueprints, drawings, and other project documents to understand the scope of work, the required concrete mix design, and any special requirements or constraints.
Concrete mixing and placement techniques: Knowing how to properly mix concrete ingredients, and how to place and finish concrete using various techniques and tools, such as screeds, trowels, and floats.
Safety practices: Understanding and following proper safety practices when working with concrete, such as wearing personal protective equipment (PPE), using proper lifting techniques, and ensuring proper ventilation.
Knowledge of local building codes: Being familiar with local building codes and regulations related to concrete work, such as minimum thickness and strength requirements, reinforcement specifications, and other standards.
Q. What other organizations are involved in standards setting in this domain? A. There are several organizations that develop standards for concrete construction. These standards are used to ensure that concrete structures are safe, durable, and meet the requirements of building codes and regulations.
ASTM International: ASTM International is a global organization that develops and publishes technical standards for a wide range of materials, products, systems, and services. ASTM has published many standards related to concrete materials and construction, including specifications for concrete mix design, testing methods for concrete strength and durability, and guidelines for concrete repair and maintenance.
National Ready Mixed Concrete Association (NRMCA): The NRMCA is a trade association that represents producers of ready-mixed concrete and provides education and resources on the use of ready-mixed concrete. The NRMCA develops standards and guidelines related to concrete mix design, quality control, and sustainability.
International Concrete Repair Institute (ICRI): The ICRI is a professional association that focuses on concrete repair and restoration. The ICRI develops standards and guidelines for concrete repair and maintenance, including guidelines for surface preparation, repair materials, and application techniques.
Dutch student radios (known as studentenzenders or campus radios) are typically non-commercial, educational broadcasting initiatives run by universities or student associations. They operate primarily as cable radio stations (kabelradio) distributed via campus or university cable networks, rather than over-the-air FM/AM transmissions. This avoids the need for expensive ether frequency licenses and aligns with their limited, non-public reach. Over-the-air broadcasting is rare for student radios due to regulatory hurdles and costs, but if pursued, it falls under general broadcasting rules.
Standards are governed by the Dutch Media Act (Mediawet), enforced by the Dutch Media Authority (Commissariaat voor de Media, CvdM) for content and permissions, and the Dutch Authority for Digital Infrastructure (Rijksinspectie Digitale Infrastructuur for technical aspects. For cable distribution, no broadcast license is required if confined to private/university networks, but equipment must comply with EU directives.
Many large research universities have significant medical research and healthcare delivery enterprises. The leadership of those enterprises discount the effect of standards like this at their peril. It is easy to visualize that this document will have as transformative effect upon the healthcare industry as the ISO 9000 series of management standards in the globalization of manufacturing.
Standardization in the field of healthcare organization management comprising, terminology, nomenclature, recommendations and requirements for healthcare-specific management practices and metrics (e.g. patient-centered staffing, quality, facility-level infection control, pandemic management, hand hygiene) that comprise the non-clinical operations in healthcare entities.
Excluded are horizontal organizational standards within the scope of:
quality management and quality assurance (TC 176);
human resource management (TC 260);
risk management (TC 262);
facility management (TC 267), and;

Four years ago Mom made a surprise visit to the ‘Hyacinth Chen School of Nursing’. Was always her dream that young women, especially from poor families, fulfil theirs to become nurses. The students were ecstatic to actually see a lady they only knew as a painting on the wall. pic.twitter.com/LBHHCLVhKy
The American National Standards Institute — the Global Secretariat for ISO — does not provide content management systems for its US Technical Advisory Groups. Because of the nascent committee, inspired by the work of Lee Webster at the University of Texas Medical Branch needed a content management system, we have been managing content on a Google Site facility on a University of Michigan host since 2014.Earlier this spring, the University of Michigan began upgrading its Google Sites facility which requires us to offload existing content onto the new facility before the end of June. That process is happening now. Because of this it is unwise for us to open the content library for this committee publicly. Respecting copyright, confidentiality of ISO and the US Technical Advisory Group we protect most recent content in the link below and invite anyone to click in any day at 15:00 (16:00) UTC. Our office door is open every day at this hour and has been for the better part of ten years.

Evolution of the standards system in Australia is tracking the evolution of the United States standards system administered by the American National Standards Institute. In many economic sectors adherence to Australian Standards is mandated by legislation, however, access to the standards are often cost prohibitive, particularly to small business and sole traders.
Principal petitioner Andrew Gardso, an electrical engineer, states,
“This in essence will force small organisations and sole traders out of business or necessitate services being performed without having access to these standards.”
Access to Standards Australia Construction codes can cost more than $2673 for three years’ access to the National Construction Code set of standards. A petition to the Australian parliament’s House of Representatives seeks free or affordable access to essential standards that govern the safety and consistency of products services and systems, including design and construction.
