Quality control (Topic II)
1. Introduction
Quality means conformity of a product to specifications and standards stipulated for the
product either by the manufacturer or the consumer before going into actual production of the
product. Quality is a relative term and varies from place to place and user to user for the same
product; perceptions of quality differ from person to person and his ability to pay.
Definition of the Quality Control
According to Bethar and Stackman, Quality Control refers to the systematic control
of those variables encountered in a manufacturing process which affects the excellence of end
product; such variable result from the application of materials, men, machine and
manufacturing condition.
Quality control is where finished products are checked by inspectors to see if they
meet the set standard. Products are inspected at the start and the end of the production
process. Any product not meeting the standards of quality set by the business will be:

Sent for rework

Discarded completely (Rejected)
Quality control ensures that no faulty product reaches the consumer as all finished products
are checked thoroughly.
2. History and Evolution of Quality Control
The concept of quality control can be traced back to medieval Europe when craftsman guilds
developed strict guidelines for how products were inspected for defects. These guilds were
responsible for creating strict rule for products and services .This craftsmanship model with
an emphasis on inspection and quality control extended through the early years of the
Industrial Revolution. In the late 19th century mechanical engineer Frederick Winslow
Taylor broke away from traditional European quality practices and developed a new
approach, which focus on increasing productivity and profitability without increasing the
number of craftsmen or strain on workers. In 1910, Taylor went on to publish "The Principle
of Scientific Management" which lay the foundation for how manufacturers should optimize
operational efficiency. In the 1920s, Engineer Walter Shewhart developed statistically
quality control method to help business improve their production processes by reducing
variation. Engineer and statistician William Deming collaborated closely with Shewhart’s
methods to the production of military good during World War II. This enable armed forced to
speed up inspection without compromising product safety or quality.
After the devastation of the word war II, Japan started to focus on quality in an effort to
rebuild its economy with the good of producing higher quality consumer goods and
minimizing raw material waste, Japanese manufacturer enlisted the help of Deming and
Joseph Juran for their quality expertise. In coming decades, manufacturers continued to
refine quality management methods, going beyond inspection to focus on strategies that also
incorporated processes and people for an end-to-end quality management system. Instead of
Page 1 of 13
Quality control (Topic II)
relying solely on product inspections, Japanese manufacturer adopted a total quality strategy
which hell all workers accountable for improving operational process. This new total quality
approach enables Japan to produce increasingly higher quality product at lower prices and
resulted in an economic boom in the decades that followed. The Toyota Production System
was developed during this period, focusing on minimizing inventory and waste. This
development represents one of the earliest modern forms of a quality management system. By
the 1970s, Japan was out-competing the U.S. in automobiles and electronics manufacturing.
As consumers bought up Japanese goods, U.S. companies began losing market share, leading
to cost-cutting and import restriction strategies .Japanese manufacturer began increasing their
share in American market. The American economy suffered from its inability to compete
with japan. This led business leader to emphasize an approached that embraces the entire
organization called the Total Quality Control (TQC) which focus on promoting quality,
setting the stage for a flourishing of quality and operational excellence strategies in the U.S.
In 1987, the first official version of ISO 9000 was published, leading to slow but steady
adoption by American companies. Today, quality control is an integral part of manufacturing.
3. Quality Control standards and symbols
Quality standards are set by the industry or the government and can be awarded to
organisations whose products meet certain standards or criteria. For example:
CE Marking
BSI Kitemark
 The CE mark shows that a product meets EU safety, health or environmental standards
and that it complies with EU legislation.
This mark proves that the product meets the requirements needed to sell within the
European market.
 The Kitemark shows that a product has met the minimum standards of safety and quality
according to British Standards Institution (BSI).
The Kitemark is a UK-based quality trade mark operated by British Standards Institution.
BSI checks and test products to ensure they meet minimum standards of safety and quality
These standards always need to be maintained or the quality standard will be removed from
the business. This may generate bad publicity.
Businesses that achieve recognised quality standards often gain a competitive advantage over
other businesses.
Customers perceive the products provided by these companies as superior. This may lead to
customer loyalty and the ability to charge higher prices.

Quality control (Topic II)
Cameroon’s Standards and Quality Agency (ANOR) read in French as “Agence des
Normes et de la Qualité” was created in September 2009 and became operational in
2011. ANOR is in charge of standardization, conformity assessment, certification, and
training and promotion of standards. It represents Cameroon in international standards
organizations. Cameroon currently has 4,500 building construction norms. These norms
encompass areas such as building materials that are expected to ensure security and durability
of buildings. ANOR is developing norms and standards in other economic sectors.
Quality control in civil engineering utilizes various symbols to communicate
standards and specifications. Some common symbols include:
1. Check Mark (v): Indicates that an inspection or test has passed and the item meets the
specified quality standards.
2. Cross (X): Denotes that an inspection or test has failed, and corrective action or rework
is necessary to meet quality standards.
3. Circle (O): Typically used to mark or highlight critical areas or items needing attention
during inspection.
4. Arrow: Used to indicate the direction of measurements or dimension to quality quality
control
5. Dimension Lines and Arrows: Show the size, shape, and location of components,
ensuring adherence to design specifications.
6. Cloud: Encloses areas requiring clarification, revision, or further attention.
7. Weld Symbols: Specific symbols used to indicate the type and quality of welds required.
8. Surface Finish Symbols: Represent surface finish requirements such as roughness or
smoothness.
9. Quality Control Inspection Symbols: These can include various codes or markings
specific to the project or organization for tracking and documentation purposes.
These symbols aid in ensuring that construction activities adhere to design specifications and
quality standards, protection, safety, durability, and performance in civil engineer
Page 3 of 13
Quality control (Topic II)
Principle of quality control
The quality control system is based on the principle of PDCA (Plan → Do → Check → Act)
cycle. The PDCA cycle also known as PDSA cycle, where ‘S’ stands for ‘study’ or Deming’s
cycle is an iterative design and management method used in businesses, companies and
enterprises for the control and continual improvement of processes and products. The PDCA
cycle is usually represented as on the figure below. Where ’PLAN’ aligns with quality
planning, ’DO’ describes the policies, procedures, and processes for laboratory testing, while
‘CHECK’ involves quality control of the laboratory production processes and ‘ACT’ relates
the actions based on the results obtained such as decisions on the acceptability of production,
root cause identification, and quality improvement.

Quality control symbols play a crucial role in manufacturing and engineering
processes. Here are some important reasons for using quality control symbols:
1. Standardization: Quality control symbols help standardize communication about
specific requirements, tolerances, and inspections across different teams and departments.
They ensure that everyone interprets the information consistently.
Page 4 of 13
Quality control (Topic II)
2. Clarity and Understanding: Symbols provide a clear and concise way to convey
complex information related to quality standards, measurements, inspections, and
processes. This helps avoid misinterpretation or ambiguity.
3. Efficiency: By using standardized symbols, teams can communicate more efficiently,
saving time and reducing the chances of errors or misunderstandings during production or
inspection.
4. Internationalization: Many quality control symbols are internationally recognized,
enabling effective communication in global supply chains where different languages and
measurement systems may be used.
5. Quality Assurance: These symbols help ensure that products meet specific quality
standards and specifications. They guide workers in performing tasks accurately and
consistently to maintain quality.
6. Cost Reduction: Using quality control symbols can reduce the likelihood of defects or
rework, ultimately lowering production costs and improving overall efficiency.
7. Compliance: Symbols often represent compliance with regulatory requirements, industry
standards, or customer specifications, ensuring that products meet necessary criteria.
In summary, quality control symbols are essential tools for enhancing communication,
standardization, and compliance within manufacturing and engineering industries, ultimately
contributing to improved product quality and operational efficiency.
4. Quality Control Approach for Civil Engineering
Construction
1 Introduction
The specific construction process of civil engineering is usually affected by various external
factors, and the impact of these factors will seriously hinder the improvement of civil
engineering construction quality. In response to this problem, construction companies should
strengthen the control of civil engineering construction quality according to the actual
construction conditions, and improve the construction efficiency of civil engineering, thus
promoting the long-term development of construction enterprises. To better understand
quality control approaches let’s take a look at some factors affecting quality control in civil
engineering construction
2 The main factors affecting the quality of civil engineering construction
2.1 The overall quality of construction workers needs to be improved
In the actual construction process of civil engineering, the overall comprehensive quality of
construction workers directly affects the construction quality of civil engineering. The
comprehensive quality of construction workers mainly includes: job responsibility, quality
control awareness, construction awareness, safety awareness, work attitude and professional
skill level. However, at present, most construction workers in construction enterprises are
mostly migrant workers. Relatively speaking, migrant workers receive relatively low levels of
education, which not only lacks safety awareness, but also lacks comprehensive
Page 5 of 13
Quality control (Topic II)
understanding of specific construction procedures. It is difficult to accurately grasp the key
points of construction skills, lack of professional construction skills, and poor quality control
awareness, and these factors will have a direct impact on the construction quality of civil
engineering.
2.2 Influence of environmental factors on the quality of civil engineering construction
At present, most of civil engineering projects are open air and it is easily affected by the
climatic environment and geological factors, thus seriously hindering the improvement of
civil engineering construction quality. In the actual construction of civil engineering, there
are some differences in temperature, geological environment, etc., so the overall quality of
civil engineering also has certain differences. Therefore, before the specific construction, the
construction enterprise should strengthen the exploration of the surrounding environment of
the construction site, and combine the results of the construction site exploration to put
forward specific requirements for the quality control of civil engineering construction, and at
the same time formulate a practical and detailed construction plan to realize the civil
engineering improvement of construction quality
2.3 Influence of construction material quality on construction quality of civil engineering
In the civil engineering construction process, the performance and quality of construction
materials directly affect the construction quality of civil engineering. However, some
construction companies usually pursue economic efficiency too much. In the actual
construction of civil engineering, in order to save the construction period, the construction
method is chosen blindly. When selecting the construction materials, in order to save
construction costs, low priced and poor quality materials are chosen. The construction
materials that do not meet the standards will seriously affect the improvement of the quality
of civil engineering construction. Waterproof materials and fireproof materials required for
civil engineering construction that have not reached the corresponding quality standards, will
cause certain defects in civil engineering and seriously affect the construction quality of civil
engineering.
2.4 Influence of construction quality control mechanism on construction quality of civil
engineering
If we want to effectively implement the quality control of civil engineering construction, we
must build a perfect construction quality control mechanism, and with the continuous
development of construction enterprises, endure to innovate and improve the quality control
mechanism of civil engineering construction, so as to promote the ordered civil engineering
construction. At this stage, in the civil engineering construction, there is a lack of perfect
construction quality control mechanism. On the other hand, the construction quality control
mechanism has not been well integrated with relevant laws and regulations, and the relevant
staff members' legal awareness is relatively weak, which has laid a lot of hidden dangers for
the quality of civil engineering construction. On the other hand, the construction quality
control work should run through the whole process of civil engineering construction, so as to
effectively improve the overall quality of civil engineering

Quality control (Topic II)
3 Effectual ways to control the quality of civil engineering construction
3.1 Pay attention to improve the overall quality of construction workers
If you want to effectively control the quality of civil engineering construction, you need to
pay attention to improve the comprehensive quality of construction workers. The specific
approach is shown in Table 1
Table 1. Specific approach to improve the comprehensive quality of construction workers

workers
For existing construction workers, training on their professional skills
and safety awareness should be enhanced to improve the quality of
civil engineering construction and reduce the chance of safety
accidents.
3.2 Strengthening the inspection of the quality of civil engineering construction

3.3 Strengthening the control of the quality of civil engineering construction materials
There is a close relationship between the quality of civil engineering construction materials
and the overall quality of civil engineering. Under such circumstances, construction
enterprises should strengthen the control of the quality of civil engineering construction
Page 7 of 13
Quality control (Topic II)
materials. In combination with the specific requirements of civil engineering construction,
special personnel are arranged to purchase materials, and the purchased construction
materials must meet the corresponding quality standards. For example, in the process of
purchasing materials, it is necessary to comprehensively examine the material market and
conduct a comprehensive analysis of the actual situation of the material suppliers. Inclusively
compare the type, specification and quality of the construction materials, and strictly check
the materials entering the construction site to strictly control the quality of the construction
materials. After the construction materials enter the construction site, special personnel are
required to manage the construction materials. It should be noted that the construction
materials should not be stacked in the exposed air to avoid the construction materials being
affected by climatic factors thus reducing the quality of the materials. Thereby the quality of
civil engineering construction is improved.
3.4 Strengthening the improvement of civil engineering construction management system
During the civil engineering construction, the construction enterprise should combine the
actual construction of the civil engineering project and strengthen the improvement of the
civil engineering construction management system, so as to effectively manage the whole
process of civil engineering construction. In the process of perfecting the civil engineering
construction management system, we should pay attention to improve safety awareness, do a
good job of safety precautions, and avoid accidents, so as to ensure that all aspects of civil
engineering construction can pass the inspection, thus ensuring the smooth progress of civil
engineering construction. In addition, we should pay attention to strengthen the overall
control of the key links in civil engineering construction, and the special personnel should
strictly monitor all aspects of civil construction, so as to effectively improve the construction
quality of civil engineering.
3.5 Strengthening the innovation of civil engineering construction technology
In the civil engineering construction process, it is necessary not only to strengthen the
management of construction equipment, materials, staff, etc., but also to focus on
strengthening the innovation of the construction foundation. This is because, in addition to
construction equipment, materials and staff and other factors that will affect the quality of
civil engineering construction, construction technology will seriously affect the construction
quality of civil engineering. New construction techniques are created by removing many
shortcomings in traditional construction techniques Comparison between traditional
construction techniques and new construction techniques is shown in Table 3.

Therefore, construction enterprises should strengthen the continuous innovation of civil
engineering construction technology to make up for the deficiencies in the traditional
construction technology, thereby improving the construction quality.
4 Conclusion
In summary, the factors affecting the quality of civil engineering construction mainly include:
the comprehensive quality of construction workers, construction materials, construction
environment and the perfection of construction quality control mechanism. The quality of
civil engineering construction not only affects the overall efficiency of civil engineering, but
also affects the long-term development of construction enterprises. Therefore, construction
enterprises should strengthen the control of civil engineering construction quality.
5. Types of quality control documents on site and in civil
engineering field.
1. The site plan is a drawing that shows the layout, dimensions, and features of the site,
such as the boundaries, elevations, utilities, drainage, landscaping, and structures. It is
used to guide the site preparation, grading, excavation, and construction activities, and to
ensure that the site conforms to the design and the zoning regulations. The site plan
should be updated regularly to reflect any changes or modifications that occur during the
project.
2. Material test reports; are documents that certify the quality and performance of the
materials used in the site development, such as soil, concrete, asphalt, steel, and
aggregates. They are issued by accredited laboratories that conduct various tests on the
samples of the materials, such as compaction, strength, durability, and composition. They
are used to verify that the materials meet the specifications and standards required for the
project.
3. Inspection reports; are documents that record the results of the inspections conducted on
the site development, by the contractor, the client, or a third-party inspector. They are
used to check the quality and compliance of the work done on the site, such as the
installation, alignment and levels
4. Change Orders; are documents that authorize and document any changes or deviations
from the original contract or scope of work for the site development. They are used to
adjust the schedule, budget, specifications, or design of the project, due to unforeseen
circumstances, client requests, or contractor suggestions. They are also used to
communicate and agree on the terms and conditions of the changes, such as the cost, time,
and quality implications, and to avoid any disputes or conflicts that may arise from the
changes.
5. The quality assurance plan; is a document that outlines the policies, procedures, and
standards for ensuring the quality of the site development project. It is used to define the
Page 9 of 13
Quality control (Topic II)
roles and responsibilities of the parties involved in the project, such as the contractor, the
client, and the quality manager. It is also used to establish the quality objectives, criteria,
and methods for the project, such as the quality control activities, tests, inspections,
audits, and reviews.
6. As-built drawings; are drawings that show the final and actual condition of the site
development, after the completion of the project. They are used to document any
differences or variations between the design and the construction of the site, such as the
location, size, shape, and orientation of the elements and features. They are also used to
provide accurate and updated information for the operation, maintenance, and future
modifications of the site.
Concrete Mix Design Reports
The Concrete Mix Design Report is a comprehensive document detailing precise ingredient
proportions and procedures for creating concrete suitable for a specific construction project.
It ensures the resulting concrete meets structural and performance requirements. Typically
prepared by qualified civil engineers or concrete technologists, these reports are submitted to
project stakeholders for approval before concrete production. They serve as blueprints for
producing consistent, high-quality concrete meeting design and performance specifications.
Reinforcement Inspection Reports
The Reinforcement Inspection Report is a detailed record of inspections on reinforcement
materials in civil engineering and construction, especially in reinforced concrete structures. It
ensures that elements like steel bars or mesh meet design specifications and are correctly
installed per industry standards. Typically prepared by qualified inspectors or engineers,
these reports document the quality and integrity of reinforcement materials and installations.
They provide assurance that project structural elements meet safety, durability, and
performance standards.
Soil Compaction Test Reports
Soil Compaction Test Reports document test results assessing soil compaction during
construction. They ensure soil beneath structures is properly compacted to prevent settlement
or failure. Prepared by qualified geotechnical engineers or technicians, these reports record
compaction efforts, ensuring compliance with project requirements. They are crucial for
ensuring stability, performance, and longevity of structures built on compacted soil.
Daily Inspection Reports
Daily Inspection Reports document observations, findings, and activities during daily
inspections at construction sites. They ensure compliance with safety regulations, quality
standards, and project specifications. Prepared by site supervisors, construction managers, or
safety officers, these reports are submitted to project managers, contractors, and regulatory
authorities. They provide a detailed record of site conditions and progress, promoting
transparency, accountability, and adherence to project requirements and safety standards.

Welding Procedure Specifications (WPS)
Welding Procedure Specifications (WPS) are detailed documents outlining instructions and
guidelines for welding operations, ensuring adherence to established standards. Developed by
qualified welding engineers or technicians, WPS ensures consistency, repeatability, and
quality in welding. It provides a standardized framework for planning, executing, and
documenting welding activities, aiming to minimize errors, defects, and safety hazards
associated with welding processes.
Non-Conformance Reports (NCRs)
Non-Conformance Reports (NCRs) document instances where work, materials, or processes
fail to meet specified requirements or standards. They're created during inspections or audits
when deviations from established quality standards are found. NCRs are vital for quality
management systems, identifying deviations promptly and facilitating corrective action. They
aid continuous improvement by pinpointing areas needing attention and preventing
recurrence of similar issues. Additionally, they serve as records of quality-related incidents
and actions taken to uphold or enhance quality standards.
Asphalt Mix Design Reports
Asphalt Mix Design Reports detail the specific proportions and characteristics of asphalt
mixtures for road construction and pavements. Prepared by qualified civil engineers or
pavement specialists, these reports outline methodologies, materials, and testing procedures
to meet project requirements. They serve as the foundation for producing asphalt mixes that
meet performance and regulatory standards, ensuring durability and safety. These reports
provide a systematic approach for designing, testing, and evaluating asphalt mixes, aiming
for optimal performance and cost-effectiveness in construction projects.
