QualIty MANAGEMENT
Definition of Quality
Quality in the constructed project is achieved if the completed project conforms to the stated requirements of the principal participants (owner, design professional, constructor) while conforming to applicable codes, safety requirements and regulations.
CIVL 493 CONSTRUCTION MANAGEMENT

4. CIVL 493 CONSTRUCTION MANAGEMENT
QualIty MANAGEMENT
Management of quality normally involves three steps:
Quality planning – determining the relevant quality standards
Quality assurance – planning the quality activities
Quality control – keeping errors out of the process
CIVL 493 CONSTRUCTION MANAGEMENT

5. QualIty Control/QualIty Assurance
Quality Assurance……. ….encompasses both quality engineering and quality control Quality Assurance is……. …..the application of standards and procedures to ensure that a product or facility meets or exceeds desired performance criteria
CIVL 493 CONSTRUCTION MANAGEMENT

6. QualIty Control/QualIty Assurance
Quality Assurance is…….
…..documentation to verify the results obtained
Quality Engineering describes procedures to ensure the design for a structure proceeds according to recommended and mandatory criteria set by:
related trade and professional associations
building code authorities
federal, state, and local government entities
CIVL 493 CONSTRUCTION MANAGEMENT

7. QualIty Control/QualIty Assurance
Quality Control includes:
setting specific standards for construction performance, usually through plans and specs
measuring variances from the standards
taking action to correct or minimize adverse variances
planning for improvements in the standards
The architects and design engineers set the criteria for construction, QC ensures that the physical work conforms to those standards
CIVL 493 CONSTRUCTION MANAGEMENT

8. QualIty Control/QualIty Assurance
THE ISO 9000 SET OF STANDARDS
The frame of reference for quality assurance is the ISO set of standards. The emergence of the ISO Quality Systems standard greatly increased the interest in formalized quality and certification. The role of ISO has also been important in coordinating the various national systems (Euronorm EN, TS, etc.) ISO 9000 registration, or certification, is increasingly essential for anyone wishing to supply large corporations or to tender for public contracts.

9. QualIty Control/QualIty Assurance
Elements of Quality include:
Quality Characteristics
Quality of Design
Quality of Conformance
CIVL 493 CONSTRUCTION MANAGEMENT

10. QualIty Control/QualIty Assurance
Quality Characteristics……
dimension
color
texture
strength
CIVL 493 CONSTRUCTION MANAGEMENT

11. QualIty Control/QualIty Assurance
Quality of Design…….
Defines tolerances or ranges of acceptable variation for attributes such as:
size, spacing, clearance, strength, finish, etc.
Designers must understand the impact that higher standards and tighter tolerances have on cost
standards of quality should be appropriate to the intended function and appearance
CIVL 493 CONSTRUCTION MANAGEMENT

12. QualIty Control/QualIty Assurance
Quality of Conformance…….
The degree to which the physical work conforms with the standards.
Often measured in terms of “rate of rejection”
Example:
“x” rejects per 100 or 1000
Often applies statistical concepts and techniques

“Quality in the Constructed Project”
a comprehensive manual published by the ASCE
includes guidelines and recommendations for owners, designers, and constructors on how to provide quality in constructed projects
addresses peer reviews

NON-CONFORMANCE REPORTS
A non-conformance report (NCR) is an important instrument to register works that have been performed not in accordance with specifications. The finding of improperly done site work causes a NCR to be ‘raised’ and signed by both contractor and Engineer. The procedure for an NCR can be simplified as follows:
A non-conformance is observed on site  NCR is raised and registered
NCR is reviewed, typically by Engineer in collaboration with designer and contractor, etc.
Engineer decides the disposition (action to be taken), these are typically one of the following: Demolish/Rework, Repair or Accept-as-is.
Contractor carry out the disposition
Works are checked to be in conformance with Engineers disposition
Contractor takes appropriate steps to avoid recurrence

16. QualIty Control/QualIty Assurance
A Quality Manager may have the following duties:
Setting up the quality system
Writing procedures
Staff training
Monitoring performance of QA system
Coordinate sampling of construction materials
Ensure compliance with ISO9001 through internal quality audits
Ensure that subcontractors QA system conforms with contract requirements
Working with external assessors
Revising and continuously improving the system
