All services are focused on interpreting, mitigating, and/or managing the risks associated with the winter performance of buildings and structures.  In-short, providing both owners and designers with the confidence that a feasible plan can be developed and implemented addressing both operational and design risk.

Service Types:

As a core service, a Design Review Consultation is a full scope assessment that provides detailed recommendations developed to mitigate and manage potential hazards through a holistic approach to risk management. The service includes a complete drawing review in combination with analysis and interpretation of historical meteorological conditions, producing a site specific prediction of microclimate conditions, and the corresponding relationship with the building envelope. Results of the assessment are communicated through an interactive consultation process structured to assist in a complete and detailed integration of risk reduction strategies.

The Detailed Mitigation Development phase, conducted as part of the Design Review Consultation (above), provides additional consultation and experience based answers to the design teams’ detailed questions, allowing for the successful implementation of mitigation recommendations within the design.

An economical overview of design drawings, at any stage in design, focused on the identification of potential falling ice and snow issues and the offering of expert advice through consultation. The results of this consultation will be communicated in a confidential manner, allowing decision makers to assess the availability and feasibility of potential mitigation options before proceeding with remediation.

Mock-up testing investigates ice and snow formation and behavior on building facades, roofs and exterior features, providing validation and/or refinement to building detailing and mitigation strategies. Tests are conducted in a temperature controlled chamber where a mock-up is exposed to multiple test scenarios of snow, ice, and rain, with calibrated temperature cycling, replicating the characteristics of winter storm conditions that have been known to produce ice and snow release.

Winter Operational Guidelines address design risk by informing building ownership and future operations personnel of the design actions implemented; and, the future need for operational efforts to complete a comprehensive ice and snow management strategy.

Developed in parallel with the Design Review Consultation, Winter Operational Guidelines are project specific, anticipating winter performance of the completed building, recommending procedures and instruction for observation, monitoring, training, and pro-active practices.

As an extension of the Winter Operational Guidelines service, one of our consultants will visit your facility and conduct a training session.  The session will instruct operations personnel in regard to: pre-winter preparedness, winter storm action planning, responsibilities, and implementation of winter observation inspections.

The training session will provide an understanding of the severity and re-occurrence frequency of potential ice and snow accumulations, along with methods and procedures developed to reduce risk of a potential hazard to people and property.

A Snow Deposition Assessment is beneficial for large exposed roof surfaces, sloped wall surfaces, and unique building geometries, which often produce challenging microclimate conditions.  A proposed design can benefit from microclimate interpretation, which can positively influence structural design and ice and snow mitigation assumptions.  If  problematic conditions are not anticipated at the design stage, hazardous consequences in the form of large masses of sliding, moving, or falling ice and snow can result, contributing to damage or injury.

A consultant will travel to your project site and conduct an inspection of installed ice and snow mitigation components.  An inspection is particularly useful to identify potential deficiencies that could negatively impact hazardous ice and snow formation.

With a focus on the need for immediate action, our consultants will review incident reports, along with meteorological and site conditions to determine the cause with respect to sliding, falling, or wind released ice and snow, then respond with recommendations for both intermediate and long-term mitigation strategies.

Our consultants are regarded as leading experts in the specialty field of ice and snow formation, behavior, and release from buildings and structures. Their knowledge has been gained through decades of incident investigations, field studies, mock-up testing, and project design consultation.  Their combined knowledge of building science principles, microclimate analysis, architectural designs, and construction background, allows our consultants to contribute expert and specialized knowledge to your ice and snow related situation.

The Snow and Ice Barrier Development service, included as part of the Design Review Consultation, assists designers in the detailed development of custom ice and snow retention devices and their related details.

In support of a Property Condition Assessment or a Facade Assessment conducted by a third party, our consultants can offer review, analysis, consultation, and expert advice, providing identification and remediation recommendations specific to the potential for falling, sliding, or wind released ice and snow.

 Do you have a sloped facade?

Sloped facades collect significantly more ice and snow than a vertical facade. However, because the total accumulation is nowhere near that found on lower sloped roofs, structural snow load requirements typically do not apply.  This often leads to the incorrect assumption that there will not be enough accumulation to cause a safety hazard from falling ice, snow or icicles.  This is where our expertise can help assess and mitigate any potential issues.

Sloped walls can be challenging issues for ice and snow collection and require specialized knowledge to mitigate potential hazards.

 Do you have a Large Sloped Roof?

We will help determine the most efficient and practical approach to drifting, sliding, and release of snow and ice on large roof surfaces. Specifically our experience includes the investigation of past designs that did not work, along with substantial experience directing design teams through the risks and options of implementing a successful design.  We can help your team avoid the pit-falls that cost time and money without compromising on risk reduction.

Large roofs behave differently than smaller roofs and experience larger issues.

 Do you have Unique Geometry?

Using our microclimate expertise, your building will be evaluated for the influences of site placement, building orientation and geometry, as well as, an assessment of both roof and facade details.  Design challenges with rain screen and double facades, solar shade structures, protruding mullions and fins, can all be assessed and customized or mitigated to reduce ice and snow collection, thereby reducing hazardous falling ice and snow.

Complex building shapes, sloped facades, and roof or facade components tend to influence and increase ice and snow issues.

 Do you have a Tall and/or High Performance Building?

Tall and/or High performance buildings are proving to behave differently in terms of envelope winter performance.  This is thought to be influenced by reduced facade heat loss due to: increased insulation, improved thermal isolation, and/or improved energy efficiency of internal heating strategies.  Using our specialized expertise the potential, severity, frequency, and magnitude of falling ice and snow issues can be assessed and explained in terms of relative risks.  This is followed by the development of recommendations for design and/or management style risk reduction strategies.

Tall and high performance buildings can experience colder exterior skin temperatures, collecting more winter precipitation.
