Roof Snow Deposition and Sliding Impact Assessment
The Design Review or Risk Assessment is the core MI&S service and involves a complete drawing review and an analysis of long-term, historical meteorological data in order to predict site-specific microclimate conditions and their corresponding relationship with the project design.
This microclimate analysis considers multiple variations of winter precipitation that are known to generate ice and snow formations on buildings and structures. These variations are assessed in combination with design geometries, site orientation and the specific architectural details that are identified to be susceptible to ice and snow formation and release.
For clients requiring existing building investigations, this assessment extends to reviewing photographs and incident reports, as well as conducting interviews with operations personnel and building management.
With all service offers, MI&S recommends a consultation session. Typically, the consultation occurs at the completion of the Design Review or Risk Assessment and prior to the issuing of a written report.
The purpose of a consultation session is to present the results and findings, discuss any project-specific evaluation criteria and review available options or recommendations for mitigation.
The goal of this step is to supply the client with enough information to decide on the most appropriate project criteria and mitigation plan for the project. MI&S has found that the consultation step is immensely helpful and important for designers and owners as it helps to communicate our experience and jointly develop economical, practical and aesthetically acceptable mitigation strategies.
Typically, mitigation strategies can take the form of minor design modifications, the addition of commercial or customized ice and snow retention products, and recommendations for observation and operational management of the completed building or structure.
MI&S recommendations are provided through a holistic approach to risk management and are formed by immense expertise in the field of building science principles, microclimate analysis, architectural designs and construction background.
Following the consultation session and subsequent agreement on the most appropriate evaluation criteria and mitigation strategies to be incorporated into the design, MI&S will develop detailed recommendations in a draft report, providing mitigation device locations and layouts, as well as dimensions for design modifications that reduce risk.
This order of events provides an organized and effective process of developing economical, effective, practical and aesthetically acceptable recommendations that can be efficiently implemented into the project design drawings and documents by the design team.
The MI&S report will be issued in a draft format that documents the methodology, analysis and review results, as well as the detailed recommendations for implementation into the design.
A final report will only be issued upon request and will include recommendations for winter operational procedures to observe and manage the building, as any ice and snow mitigation strategy cannot completely eliminate all potential for hazard, and therefore must be supported by informed and responsible operational procedures.
MI&S offers services to work closely with the client to complete additional drawing reviews, respond to questions, assist with product suppliers and participate in subsequent team meetings that pertain to snow and ice mitigation strategies or cost cutting.
This additional support service is offered to ensure the final design accurately incorporates all of MI&S recommended mitigation strategies so they remain effective and practical.
A comprehensive approach to ice and snow risk reduction and management includes responsible practices in both the design and subsequent operation of a building, structure and project site.
Therefore, MI&S recommends that a project-specific Winter Operational Guidelines document be developed in concert with the design review and risk assessment services. This allows clients to evaluate the design response in relation to the corresponding requirements for operational management.
Winter Operational Guidelines are developed for incorporation into the standard operating procedures of the completed project and include specific instructions for winter preparedness, responsibilities, observations, actions, instruction, documentation and management actions, such as snow removal and the deployment of temporary restricted access.
To investigate, refine or validate design or mitigation details, we perform mock-up testing in a large temperature-controlled test chamber where snow, ice, wind and freezing rain can be generated in a repeated and controlled manner to replicate of real-life conditions.
MI&S’s performance mock-up testing is based on expertise and knowledge gained from years of studying building performance, incident investigations, and field studies of many of the world’s most prominent buildings that have experienced problematic winter performance. For your next project MI&S can plan, execute, analyse and report on the installation, instrumentation and testing of a customized Performance Mock-Up, recommending any required design or mitigation strategy modification or refinements.
A MI&S developed test plan will include any required test configurations, that exposing the Performance Mock-Up to a regiment of wind, snowfall, ice generation and melting (e.g. wind, snowfall, windblown snow, freezing rain, wind driven freezing rain, etc.) to evaluate and validate the mock-up under the anticipated typical and extreme winter conditions.
During this service, MI&S will specify the requirements for the mock-up design, develop the test plan, coordinate with the mock-up designers, device suppliers and laboratory staff. This will be followed by the, development of a comprehensive test report that summarizes the test plans, results and final recommendations.
As an extension of the Winter Operational Guidelines service, one of our consultants will work with a separate facilities consultant to develop a customized staff instruction program.
We will then visit your facility to conduct instruction sessions with management and operations personnel on the outlined procedures, which include pre-winter preparedness, winter storm action planning and the assignment of associated responsibilities pertaining to winter observations and inspections.
The instruction sessions will provide education on the severity and frequency of potential ice and snow accumulations, the anticipated behavior of the building or structure under typical and more extreme winter conditions, along with the recommended operational procedures designed to reduce the risk of a potential hazard to people and property.
(OFFERED VIRTUALLY AT THIS TIME)
A consultant from MI&S will travel to your project site to conduct an review of the recommended mitigation components that are either in the process of or already installed to mitigate falling, sliding or wind-released ice and snow.
A review of mitigation is useful to identify potential performance deficiencies in the components that could be contributing to hazardous snow and/or ice formation.

Michael’s extensive experience with ice and snow behaviour has led to collaborations with designers and manufacturers of ice and snow barriers and heating cable and controls. These collaborations within the industry were initially developed to assist with standardization of specifications, and soon led to Michael’s role with ASTM International as a task group co-chair for the Evaluation of Ice and Snow Accretion on Buildings and Structures. Within ASTM he is leading two key areas of work within the task group, first working with barrier manufacturers to develop test standards, and second working with the building design industry to establish standard guides and methods for the evaluation of snow and ice accretion on building and structures.
