1.8 Avoiding Problems through Best Practices & Processes

Avoidance of the problems outlined above and achieving desired project objectives requires good practice to be implemented throughout the mechanical insulation process; it also requires participation of a range of project stakeholders.

1. Example Project Processes

The following flow chart illustrates a typical process followed during a development project, as it pertains to mechanical insulation.

2. Mechanical Insulation Roles and Responsibilities

Following are typical roles and responsibilities needed to achieve successful projects with respect to mechanical insulation objectives. These roles and responsibilities will vary somewhat by project and jurisdiction, and are not intended to replace roles and responsibilities that are required through regulation; rather they are intended to highlight the elements generally needed for good mechanical insulation practice throughout all phases of a project.
Table 1.8.2 - Mechanical Insulation Roles and Responsibilities

Project Participant Key Role Best Practice Elements
Building Developer, Owner, Project Manager Hiring, business case review, overall decision making Understands the importance and value of mechanical insulation to their project.Hires engineers and contractors familiar with, and qualified in, mechanical insulation.
Mechanical Engineer Design and review Understands design objectives, code requirements and applicable standards.Helps developer/owner/project manager understand the business case for mechanical insulation.Develops or adapts up to date mechanical insulation specifications that are appropriate for each project.Conducts informed and timely field reviews to ensure the specification is fulfilled and best practices are implemented, and design objectives are not compromised by “value engineering.”

Ensures inspections have been completed by a qualified party – e.g., 3rd party inspector or registered professional.

Mechanical Contractor Subcontracting or installation If subcontracting: subcontract to qualified mechanical insulation contractors.Familiar with Code objectives and material characteristics.Awareness of performance characteristics of the mechanical systems and implications of “value engineering” or incomplete insulation.Ensure insulation is installed only when the building is ready and dry.

If installing: qualified in mechanical insulation installation best practices.

Mechanical Insulation Contractor, Tradesperson Subcontracting or installation If subcontracting: subcontract to qualified mechanical insulation installers.If installing: qualified in mechanical insulation installation best practices.
3rd Party Inspector Inspection Conducts informed and timely inspections to ensure best practices are implemented.Qualified in mechanical insulation best practices and quality assurance.
Local government building inspector Inspection Qualified in mechanical insulation best practices and quality assurance and conducts informed and timely inspections to ensure best practices are implemented.OREnsures inspections have been completed by a qualified party – e.g., 3rd party inspector or registered professional.
