Snow Management

“A Morning Snow–Hudson River” 1910 George Wesley Bellows | Smithsonian American Art Museum

This time of year in the Northern Hemisphere we keep an eye on snow management  standards; among them titles developed by the Accredited Snow Contractors Association.  The barriers to entry into this domain are relatively low and, arguably undisciplined; hence the need for standards setting.  Even when only partially adopted, use of ANSI accredited standards reduces the “wheel reinvention” that is common to the business side of the education industry when new initiatives, or continuous improvement programs are undertaken without consideration of already existing leading practice discovery by ANSI-accredited technical committees.  Start here:

ASCA Standards Home Page

The parent title for the emergent ASCA bibliography is System Requirements for Snow and Ice Management Services; free to ASCA members.  The current version is dated 2014 and will likely be updated and/or re-affirmed.  The circumstances of the pandemic has slowed the work of many standards setting committees.  The safety and sustainability concepts remain intact, however.  Among them:

  • If snow can be removed from a lot or hard surface and appropriate room exists, always push the snow as far back as possible beyond the curb or lot edge to make room for additional snow.
  • If snow cannot be removed from a lot or hard surface, always place snow piles on a predetermined spot approved by the client and marked on the snow contractor’s preseason site report.  
  • Do not pile snow in a handicap parking space.
  • Do not bury or plow snow onto a fire hydrant, post indicator valve, or fire hookup along the building wall.
  • Avoid placement of snow piles where thaw/melt off can run across the parking lot surface. Try to place piles near drain grates to avoid icy situations during thaw-and-refreeze periods.
  • Do not push snow against a building.
  • Do not block building doorways or emergency exits.
  • Do not block pedestrian walks or paths with snow piles.
  • Do not push snow onto motor vehicles.
  • Do not plow snow in front of or bury trash containers. Sidewalk labor must shovel inside trash container enclosure for access to the doors. If the container is not in an enclosure, create a clear path to the access doors or panels.

"Liberty, when it begins to take root, is a plant of rapid growth" - (Letter to James Madison, March 2, 1788)“The cold was our pride, the snow was our beauty.” — F. Scott Fitzgerald ('Wiinter Dreams' 1922)

ASCA has more recently released another title — Standard Practice for Procuring and Planning Snow & Ice Management Services — that seems (by its title alone) to be a companion consensus product.  From its prospectus:

This standard of practice covers essential procuring and planning for snow and ice management services. Standards for procuring and planning are essential for business continuity and to improve safety for patrons, tenants, employees, and others in the general public. Knowing how to describe service requirements in a snow and ice management request for proposal (RFP) is an important component to providing effective services, particularly where winter weather is a variable. This standard practice provides guidance on the snow and ice management procurement and planning process to aid in the creation of RFPs, contracts, agreements, and monitoring procedures. This standard will not be submitted for consideration as an ISO, IEC, or ISO/IEC JTC-1 standard.

Apart from these titles, we do not see any recent happening in the ASCA standards setting enterprise.  We will pass information along as it becomes available.  Alternatively, you may communicate directly with ASCA, 5811 Canal Road  Valley View, OH 44125, Ph: (800) 456-0707.  Most education communities employ a combination of permanent and contract staff for these services.

We maintain the ASCA bibliography on our Snow & Ice colloquia  See our CALENDAR for the next online meeting; open to everyone.

Electrical heat tracing: international harmonization-now and in the future

 

Electrical heat tracing: international harmonization-now and in the future

Abstract:  In the past, electrical heat tracing has been thought of as a minor addition to plant utilities. Today, it is recognized as a critical subsystem to be monitored and controlled. A marriage between process, mechanical, and electrical engineers must take place to ensure that optimum economic results are produced. The Internet, expert systems, and falling costs of instrumentation will all contribute to more reliable control systems and improved monitoring systems. There is a harmonization between Europe and North America that should facilitate design and installation using common components. The future holds many opportunities to optimize the design.

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.  Without electric heat tracing; much of the earth would be uninhabitable.

Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.

There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:

  1. Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
  2. Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
  3. Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
  4. Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
  5. Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.

Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.
