Basis of Design

Building envelope systems identified in a non-proprietary performance criteria outline with proprietary options. Includes warranty recommendations.
Building code (construction)
A set of regulations established by a governmental body to ensure the safety, health, and welfare of building occupants. These codes typically address the minimum requirements for structural integrity, fire safety, accessibility, energy efficiency, and other aspects of construction.

Building envelope

The physical barrier separating the conditioned interior environment from the unconditioned exterior environment. It includes walls, roof, foundation, windows, doors, and any penetrations through them.
Control layers
Elements within the building envelope that manage factors like air, water, heat, and sound. Examples include insulation, vapor barriers, and air barriers.

Division 7

A type of construction encompassing building envelope waterproofing, thermal, and moisture protection.

Fenestration

Openings in a building envelope, like windows, doors, and skylights, that allow for natural light, ventilation, and views.

Forensic Testing

The meticulous examination and analysis of a building’s control layer components — such as roofs, walls, windows, doors, decks, below-grade, planters, etc. — to identify issues causing leaks, energy inefficiencies, or strucual failures. Utilizing advanced diagnostic techniques and technologies, this process aims to uncover the root causes of failures, ensuring accurate remediation and enhancing the building’s longevity and performance.

Limited Scope Diagnostic Site Analysis

A process that begins with visual observations to identify suspect areas for subsequent targeted and isolated testing. This approach is characterized by its non-invasive nature, relying on expert visual inspection to pinpoint potential anomalies or areas of concern within a site. The primary objective is to delineate specific zones that may require more intensive investigation, thereby streamlining the process towards focused testing.

Quality Assurance (QA)

Ensures consistent quality throughout a project by planning and managing all stages, from design to delivery, to meet set standards. It’s preventative, unlike quality control which focuses on finding and fixing issues in the final product.

Quality Control (QC)

Ensures quality by actively identifying and fixing issues early on, preventing future problems and ensuring a durable final product.

Standard of care (construction)

The level of quality, skill, and diligence that a reasonably prudent contractor would be expected to possess and exercise under similar circumstances in a particular locality. This standard serves as a benchmark for evaluating construction practices and determining potential negligence.
