4What is Quality?
- Dad and son cycle across US
- Dad keeps recognizing things on the trip
- Used to be philosophy Prof.
5What is Quality?
- Quality you know what it is, yet you dont know
what it is. - But some things are better than others, that is,
they have more quality.. ... - Robert M. Pirsig, Zen and the Art of Motorcycle
Maintenance, p. 163
6What is Quality?
- Obviously, some things are better than others
but whats the betterness? So round and round
you go, spinning mental wheels.. - What the hell is Quality? What is it?
- Robert M. Pirsig, Zen and the Art of Motorcycle
Maintenance, p. 164
7 8Quality Defined
- A quality item is one that wears well, is well
constructed, and will last a long time. - There are a variety of definitions. Three most
commonly used are - Achievement of excellence
- Fitness for purpose
- Conformance to requirements.
9Definition of Quality
- Quality is conformance to requirements
- -- Philip Crosby, Quality is Free 1979
10Importance of Quality
- Lower costs (less labor, rework, scrap)
- Reputation
- Product reliability
- Market Share
- International competitiveness
11Quality Assurance (QA)
- Quality Assurance (QA)
- QA is defined as all those planned and
systematic actions necessary to provide adequate
confidence that a structure, system will perform
satisfactorily when in service.
12ISO - What does it mean?
- ISO is a word from the Greek isos, meaning
equal. - Its not an abbreviation.
13What is ISO certification?
- Does not guarantee a quality product.
- No inspection of the product is involved in
certification. - To get certified
- Have a written set of procedures for every
activity - Have your employees always follow procedures
- Pay someone to come and verify that you always
follow your written procedures - If procedures are followed, your products should
be consistently, uniformly good
14ISO Family of Standards
- ISO 90012000 Basis for certification
- ISO 90042000 to prepare for national quality
award - ISO 10006 for project management
- ISO 10007 for configuration management
- ISO 10012 for measurement systems
- ISO 10013 for quality documentation
- ISO 10015 for training
- ISO 19011 for auditing
15Certification Structure
16Quality Control (QC)
- Quality Control (QC)
- Control is preventing things from getting out of
hand. - QC are those quality assurance actions which
provide a means to control and measure the
characteristics of a material, structure,
component, or system to established requirements.

26Quality Assurance (QA) andQuality Control (QC)
- QA QC
- Assurance gives confidence that a satisfactory
product is supplied to the owner. - Control is part of the process of quality
assurance. - A client must be aware that he/she can only get a
product he is willing/able to pay for.
27Quality Management (QM)
- In order to assure the owner of a good product,
we must manage the design and construction
processes. Quality management is the term most
suitable to our purpose. - All actions, planned and systematic, necessary
to provide the owner with a satisfactory product
when in service under the constraints imposed by
resources.
28Total Quality Management (TQM)
- Top management commitment
- Input from customer
- Involvement of workers at every level
- Emphasis on design quality and process
improvement - Decisions based on information instead of opinion
- Continuous improvement through reducing
variability
29Total Quality Management (TQM)
- Team-work
- Ongoing training, and can be attained by
cascading steps - - Management awareness
- - Strategic planning
- - Implementation, and
- - Employees training
30Total Quality Management
- Continuous Improvement
- Employee empowerment, quality circles
- Benchmarking - best at similar activities
- Quality of suppliers - Just In Time
31TQM Inspection
- Inspection does not add value
- Inspectors distrusted by workers
- Increase quality and reduce need for inspectors
- Have workers do own inspection
- Before are inputs good?
- During process happening properly?
- After conforms to standards?
32TQM QUALITY COSTS GOOD, BAD, UGLY
33W. Edwards Deming
- Statistics professor, specializing in acceptance
sampling - Went to Japan after WW II
- Helped Japanese focus on and improve quality
- System (not employees) is cause of poor quality
- Fourteen Points
34Demings Paradigms
- Motivation
- Management needs to improve and innovate
processes to create results - Optimize the system toward its aim
- Cooperation is better than competition
35Joseph Juran
- Went to Japan in 1951
- Quality begins by knowing what customers want
- 80 of defects are controllable
- Quality Planning
- Quality control
- Quality improvement
36Philip B. Crosby
- In 1960s Quality is Free
- Management must be firmly behind any quality
plans -
- Do it right the first time
37Quality Competitions

40THREE ELEMENTS TO BE CONTROLLED IN A CONSTRUCTION
PROJECT
41Stakeholders
- Quality is the cement holding the owner, the
designer, and constructor together in stable
pattern where each supports the other in
producing the successful project
OWNER
DESIGNER
Quality
CONSTRUCTOR
42What are the causes of deterioration in Quality?
- Quality of design
- Lower quality design results in lower quality
construction and increased variation orders,
resulting in increased cost of the project. - Other contributing factors-
- Corruption
- Incompetent Contractors
- Poor Project Management
- Lack of Resources for Quality Management
43Construction Industry Needs
- Quality standard that is currently available to
the construction industry is the ISO 9000
quality system. - This standard has for the most part been
generally ignored by the construction industry in
Pakistan.
442. Prevention over Inspection
- Build Quality vs Inspected Quality
- The cost of preventing mistakes is generally much
less than the cost of correcting them by
inspection
453. Management Responsibility
- Success requires the participation of all
members of the team, but management is
responsible to provide the resources to succeed
464. Continuous Improvement
The plan-do-check-act cycle is the basis for
quality improvement.
47THREE MAIN COMPONENTS OF QUALITY MANAGEMENT
1) QUALITY CONTROL
2) QUALITY ASSURANCE
3) QUALITY IMPROVEMENT

51Wilfredo Pareto 1848-1923
- Italian Economist
- 80/20 rule 80 of the wealth is controlled by
20 of the people Cours d'économie politique
(1896-7) - 80/20 rule believed to apply much more widely
52PARETO CHART A graphical representation ranking
discontinuities from the most to least
significant. Used to help brainstorm what
discontinuities, if worked upon first, would be
the most likely to produce the greatest
improvement in quality.

55FLOW CHARTS Flow chart is graphical
representations of the steps involved in a
process. Constructing a flow chart helps in
better understanding of the systems involved.
56Control Charts
- The control chart is a graph used to study how a
process changes over time. Data is plotted in
time order. A control chart always has a central
line for the average, an upper line for the upper
control limit and a lower line for the lower
control limit. These lines are determined from
historical data. By comparing current data to
these lines, you can draw conclusions about
whether the process variation is consistent (in
control) or is unpredictable (out of control,
affected by special causes of variation)
57(No Transcript)
58When to use a Control Chart
- When controlling ongoing processes by finding and
correcting problems as they occur. -
- When determining whether a process is stable (in
statistical control). - When analyzing patterns of process variation from
special causes (non-routine events) or common
causes (built into the process).
59PROBLEM SOLVING STEPS WITH QUALITY CONTROL
TOOLS
60Result of Good Quality
- Produces quality designs.
- Quality designs produce quality projects.
- Quality projects have fewer variation orders
during construction. - Fewer variation orders result in lower
construction costs. - Quality designs and lower construction costs
result in lower life-cycle costs. - Quality is in the Owners best interest.
61Result of Poor Quality
- High maintenance costs.
- Projects fail, e.g., road pavements collapse.
- Cost and time overruns.
- Disputes and litigation.
- Contractor defaults and does not complete the
project.
62Developing and implementing a quality system
- Definitions (BS 4778)
- Quality system
- Quality Manual
- Quality procedures
- Quality plan
- Quality audit
63Developing a Quality System
- STAGE 1
- Chief executive of the firm should commit to
quality assurance by declaring quality policy
e.g. Towards total customer satisfaction - Make formal statement of the objectives e.g. To
achieve ISO certification in 18 months - Organize management structure and define
responsibilities
64Developing a Quality System (Cont)
- STAGE 2
- Preparation of quality manual and quality
procedures i.e. quality system - STAGE 3
- Apply quality procedures to specific contracts
when the quality system is completed and approved
internally. - Staff should be familiar with quality assurance
and understand their roles but training is
required.
65Developing a Quality System (Cont)
- STAGE 4
- Prepare quality plans and additional quality
procedures for specific contracts. - STAGE 5
- Apply quality plans to specific contracts.
Training may be necessary. - STAGE 6
- Internal and external audit of quality system
review periodically all quality manuals and
procedures.
66RESEARCH -QUALITY MANAGEMENT
- The quality of civil structure depends on the
quality of - workmanship as well the quality of materials
used in it. - Naeem Ali (2005) reported 60 of block masonry
buildings were demolished by the earth quake. - What was the reason?
- The low quality of masonry blocks
67Development phases of quality management
- Paliska (2007) presented a flow chart on how
the quality management developed in the history.
Quality control, reactive
Quality assurance, proactive
Quality management system

68The quality management divided into two categories
- Technical system
- Technical system includes the tools and
techniques used for - managing the quality.
- II. Managerial system
- Managerial system includes the QM
factors and - for those company management is
responsible - (Evans and lindsay 1999)

75Research methodology
Sample Selection The Board of investment Govt.
of Pakistan reported 29 cement companies
operating in Pakistan in 2007. These 29 companies
was taken as target population Data
collection At least two responses were taken
from each company, one from top quality control
managers and one from middle line quality control
management. Data Analysis Analysis of data
collected is done through Statistical Package for
Social Sciences (SPSS-16) Microsoft excel
(2007). Frequency distribution statistics was
used for interpreting results.
- Questionnaire Design
- The questionnaire includes four sections
- Personal information
- Company information
- Quality awareness
- This section includes the questions on the
basic terminology (i.e., QC, QA, etc.) being
implied in quality management. Responses are
taken on three scale, yes, no, or dont know - 4. Quality application
- Within this section there are three
subsections - a. Quality documentation
- This section contains the questions
about quality documentation (i.e. Quality policy,
ISO certification, etc.). The responses are taken
on three point scale, yes, No, or Dont know - b. Quality tools and techniques
- The quality tools techniques are
enlisted in three groups , tools techniques
used in quality control phase, tools techniques
used in quality assurance phase and tools
techniques used in quality improvement phase. The
responses are taken to prioritize first four
tools techniques from each category in the
sequence , always used, very often used, sometime
used, rarely used. - c. Questions on critical factors of quality
management. - The questions on 8 famous critical
factors as give by the Kanapthy (2008) are
included in this subsection and responses are
taken on 5 point likert scale, Strongly disagree
to strongly agree. -

well aware with the new terminologies (i.e. ISO
9001, TQM) of the quality management in
comparison to the terminologies (i.e. Quality
control, Quality assurance). - Eighty percent (80) respondents think that ISO
practices are essential for TQM implementation.
It showed trust on ISO practices that it can
improve the processes leading to TQM.
94Concluding Remarks
- The Pakistan standard and quality control
authority is responsible to keep an eye and is
striving for implementation of quality
management. - The study recommended that employees may be
trained for in quality management.
