Quality Management
• Definition – varied
• Mainly – Quality planning, control (QC),
assurance (QA) and improvement
• Overall quality of service or product
• AND – the means to achieve it
• Also called TQM
![Page 8: ENSURING THE QUALITY OF CONSTRUCTION MATERIALS · •No vested interest in the project •Not affiliated with the product, the contractor, owner, government, etc •THUS – fully](https://reader034.vdocuments.site/reader034/viewer/2022051814/6038074e5a14d13446697805/html5/thumbnails/8.jpg)
QM IS CRITICAL
• Longevity of the asset – this is key
• Safety
• Cost effective delivery
• Part of a quality culture – for all aspects
of a municipality’s operations
• To avoid unwanted headlines

QC AND QA IN
CONSTRUCTION
• QC - process control –
responsibility of contractor (or the
contractor’s supplier)
• QA - independent audit function
required by the owner (eg – a
municipality)
![Page 16: ENSURING THE QUALITY OF CONSTRUCTION MATERIALS · •No vested interest in the project •Not affiliated with the product, the contractor, owner, government, etc •THUS – fully](https://reader034.vdocuments.site/reader034/viewer/2022051814/6038074e5a14d13446697805/html5/thumbnails/16.jpg)
CONTRACT LANGUAGE
• MUST – detail the specifications
• MUST – identify roles and
responsibilities
• QA – independent consulting
engineering firm – P Eng oversight
• Testing – number of tests // and
certified & (for QA) independent
![Page 17: ENSURING THE QUALITY OF CONSTRUCTION MATERIALS · •No vested interest in the project •Not affiliated with the product, the contractor, owner, government, etc •THUS – fully](https://reader034.vdocuments.site/reader034/viewer/2022051814/6038074e5a14d13446697805/html5/thumbnails/17.jpg)
WHY INDEPENDENT
• No vested interest in the project

REQUIREMENTS FOR
CERTIFICATION
• BC – MOT - for referee labs (roads)
• Concrete – all work should be by a
certified lab (CCIL to CSA standard)
• Municipalities – growing interest – CCIL
is on MMCD web site
• BUT – profile needs to be enhanced
![Page 30: ENSURING THE QUALITY OF CONSTRUCTION MATERIALS · •No vested interest in the project •Not affiliated with the product, the contractor, owner, government, etc •THUS – fully](https://reader034.vdocuments.site/reader034/viewer/2022051814/6038074e5a14d13446697805/html5/thumbnails/30.jpg)
CCIL POSITION
• All contracts – especially for QA should
specify certified labs
• A definite requirement for all other lab
work – public health, environment,
products, food, etc –
• So – why NOT for construction projects
![Page 31: ENSURING THE QUALITY OF CONSTRUCTION MATERIALS · •No vested interest in the project •Not affiliated with the product, the contractor, owner, government, etc •THUS – fully](https://reader034.vdocuments.site/reader034/viewer/2022051814/6038074e5a14d13446697805/html5/thumbnails/31.jpg)
Benefits of Program
Uniformity in test procedures and
performance – and we can show data
Improvement in laboratory test standards
and quality control
Increased confidence in test results
Reduced potential for disputes
Encourages technician training and
certification
