Lawn & Garden Tools

“Le Parc Moncea” 1848  Gustave Caillebotte

The education industry in the United States is steward to large tranches of land assets; either through the Morrill Land Grant Act or municipal set-asides for public schools.  In terms of square footage, the spaces between buildings far exceeds the square footage of the built environment — and the locus of public interest and environmental regulation.   All of that square footage — usually measured in hundreds and thousands of hectares and acres — requires consideration of the competing interests of many stakeholders.

We display the accomplishments of employees devoted to the landscaping and gardening of educational organizations in a dedicated post:

Gardens and Arboretums

Landscape and garden assets have their own set of construction and maintenance tools, many of which are continually improved by global equipment manufacturers, and fall within the scope of Subcommittee 13 under parent Technical Committee 23 Tractors and machinery for agriculture and forestry administered by the Association Française de Normalisation; the French national member body to the International Organization for Standardization.

The Outdoor Power Equipment Institute (OPEI) is ANSI’s US Technical Advisory Group administrator and the Global Secretariat for ISO TC/23/SC 13.  The work program for Subcommittee 13 is linked below:

ISO/TC 23/SC 13 / Powered lawn and garden equipment

Note product standards cover many equipment classes and accessories for engine powered lawn movers, snow blowers, gardening machinery and the like.

ANSI encourages relevant stakeholders to participate in discovering standardization solutions in a broad range of technologies and markets with like-minded experts in other national standards bodies.  The full sweep of ANSI’s participation in consensus documents developed by the ISO is described in the link below:

ISO Programs – Overview

We encourage our colleagues in exterior grounds and landscaping units in the education facility industry to participate directly as a User interest in the OPEI standards development process.   OPEI Standards Staff Contacts are listed on the OPEI Standards home page linked below:

Product Safety Standards Listing

We review the developmental status of consensus products that set the standard of care for equipment used to maintain pathways, lawns and gardens in education communities.   Automation of the maintenance of these spaces is gathering pace; reducing cost and risk.  See our CALENDAR for the next online meeting; open to everyone.

The World Soil Museum hosts a range of educational programs and workshops for students, researchers, and other visitors who are interested in learning more about soil science. These programs cover topics such as soil classification, soil management, and soil conservation, and they are designed to help people understand the vital role that soils play in supporting agriculture, ecosystems, and human societies around the world.

Aggregate Pathways

As cities-within-cities, education communities are a large market for concrete manufacturers and installation contractors.   The pathways built from aggregates (“sidewalks”) are central to the function and character of the campus.   Construction and maintenance of these pathways — the cost of which depends upon the appropriate specification and application of aggregate technologies —  are a significant cost center.  They can also present pathway travel hazards and drainage problems.

The application of permeable pavements in recent years has gathered pace.  Permeable pavements typically consist of pervious concrete, porous asphalt, or interlocking concrete paver units over an open-graded base or subbase layer(s). Permeable pavements are designed to infiltrate stormwater, reduce peak flows, improve stormwater quality, and promote groundwater recharge.  They have become an integral part of low-impact development, sustainable design, green infrastructure, and best management practices for stormwater management. In order to be effective within municipal road networks, permeable pavements must be designed to provide sufficient structural capacity to accommodate the anticipated vehicle loadings while managing stormwater flows into and out of the permeable pavement.

The American Society of Civil Engineers titles are widely referenced in public safety statutes and in construction documents.   It maintains public access to its standard development enterprise at the link below:

ASCE Codes & Standards Home Page

Last year we reviewed the redline of its standard for the application of these materials — Standard for Design, Construction and Maintenance of Permeable Interlocking Concrete Pavements. — most of which dealt with administration, wordsmithing and harmonization with related consensus products.  There were no technical changes that we felt were important that were not covered in installation contractor specifications.

Comments are due January 18th.

As of the date of this post two other relevant titles open for consultation:

  • Public Comment on Supplement 3 for ASCE/SEI 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures – Comment Deadline July 11, 2021.
  • Public Comment on ASCE/SEI 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures – Comment Deadline August 2, 2021.   

The titles listed above are not directly related to Aggregate Pathways and very often the same engineering professionals that guide structural concrete best practice are involved in best practice for aggregates in the pathways.  Different materials and practice; same engineers.  CLICK HERE to key in comments into the ASCE Public Comment facility.

The ASCE catalog is a foundational catalog for all infrastructure in the United States and is continually monitored by our algorithm.  We maintain its best practice titles relevant to our industry on the standing agenda of our Pathway and Bucolia teleconferences.   See our CALENDAR for the next online meeting; open to everyone.

Outdoor Deicing & Snow Melting

Electrical Safety

“Snow at Argenteuil” | Claude Monet (1875)

Today our focus turns to outdoor electric deicing and snow melting wiring systems identified as suitable for the environment and installed in accordance with the manufacturer’s instructions.  They work silently to keep snow load from caving in roofs and icicles falling from gutters onto pedestrian pathways.

While the voltage and ampere requirement of the product itself is a known characteristic, the characteristic 0f the wiring pathway — voltage, ampere, grounding, short circuit, disconnect and control — is relatively more complicated and worthy of our attention.   Articles 426-427 of the National Electrical Code is the relevant part of the NEC

Free Access 2023 National Electrical Code

Insight into the ideas running through technical committee deliberations is provided by a review of Panel 17 transcripts:

2023 NEC Panel 17 Public Input Report (633 pages)

2023 NEC Panel 17 Public Comment Report (190 pages)

We hold Articles 427 in the middle of our priority ranking for the 2023 NEC.   We find that the more difficult issues for this technology is the determination of which trade specifies these systems — architectural, electrical, or mechanical; covered in previous posts.   Instead, most of our time will be spent getting IEEE consensus products in step with it, specifically ANSI/IEEE 515 and IEEE 844/CSA 293.

Comments on the Second Draft of the 2026 NEC will be received until April 18th.

…

454c656374726f746563686e6f6c6f6779

We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones.  Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.

Pathways 100

Today we break down the literature for exterior and interior pathways in education communities.   We limit the term “pathway” to refer to human pathways (as in egress and ingress paths); not wiring or piping pathways.   Maximum distance of travel from within a building and along an egress path toward safety is a core topic in building safety literature.  Starting 2023 we will break down coverage of subject catalogs and bibliographies:

Pathways 100: Survey of all titles for both the exterior and interior environments

Pathways 200: Review of codes, standards and guidelines for building interiors

Related recent research:

Pathways 300: Review of codes, standards and guidelines campus environment outside the buildings; all seasons

Pathways 500: Review of noteworthy litigation.   Campus pathways are rich in possibilities for legal actions so we will refresh our understanding of the landmark decisions.

This breakdown is “somewhat” inspired by recent action by ASHRAE International to expand the scope of ASHRAE 90.1 to heating and cooling environments outside buildings.   The new title of ASHRAE 901. includes the word “Site”, which is another way of saying “the world” outside buildings.   Standards Michigan commented on the consequences of doing this in the proposal stages in 2020-2021.

We might venture onto the minefield of sensitivities about signage: too much, too many, too big, too small?  There are signs everywhere in academia.

Many titles in the foregoing list are inspired by legal requirements of the Americans with Disabilities Act administered by the US Department of Justice
