"a set of processes [that are] in place to avoid deviating from requirements and standards that would meet the agreed-upon goal."
"the act of measuring—monitoring the work to ensure that the contractor’s processes are working."
QC is aIways the contractor's responsibility.
QA and QC
- Internal processes and accountability
- External inspections and audits
- Identified by QA inspections
- Identified by future occupants
: Balance these costs for
on the bottom line
The Cost of Quality
Support from HERS Rater
On-Site Subcontractor Training
Inspections with Suggestions
New Tools of the Trade
GOAL: Identify, prioritize, and greatly reduce emerging or recurring issues
A temporary task force comes together with management's support in order to create the larger framework for the QC checklist.
Based on clear, measurable requirements and standards
Includes actionable hotspot analysis
Describes integration with other trades
Includes provisions for performance-based language in scopes and contracts
Quality Management Policy
A team drafts an internal QC checklist that serves as the skeleton checklist for all similar projects. Site Managers fine-tune the checklist for their specific project and their specific subcontractors.
Based on significant specific tasks
Includes trade and individual accountability
Used as a self-check throughout construction
Integrated into standard project schedule
Quality Control Checklist
Learn to use the equipment, require subs to pre-test or pre-inspect, and keep records
Exchange information between Project Managers based on job experience
Continue your building science education
Implement Hotspot Analysis, as required
Are you passing every inspection the first time?
How do you track who's doing what?
Assign individuals to specific tasks, then train them on the processes and equipment that are available to help them succeed.
Expectations and Accountability
More insulation/ Higher R-value
More effective Insulation
Increased air tightness
Decreased envelope permeability
Smaller (and more efficient) HVAC
Indoor air quality
Narrower margin of error
New materials and methods
Limits effectiveness or efficiency
Occurs more than once
Requires resources to resolve
Cost and schedule impact
Potential unintended consequences

Trust, but verify.
“Inspection with the aim of finding the bad ones and throwing them out is too late, ineffective, costly. Quality comes not from inspection but from improvement of the process.”
-- Dr. W. Edwards Deming
Become your own expert.
"Quality problems are usually the result of failed processes."
-- John Tooley
If "workers know they won’t be blamed, they
will be more willing to work with management to improve processes and raise quality."
