1. Introduction
The construction industry plays a key role in the development and economic growth of any nation by providing the infrastructure necessary for daily life and progress [,]. However, in developing countries, this sector often faces significant challenges that limit its potential. These challenges include rising inflation, declining commodity prices, and fluctuating exchange rates [].
One of the most pressing issues is limited funding, which affects various aspects of construction projects. Insufficient financial resources restrict project scope and reduce access to high-quality materials, skilled labor, and modern technology. This financial constraint often forces compromises in critical areas, leading to poor construction conditions, a decline in the quality of the built environment, and frequent maintenance problems.
Poor transportation networks make it difficult to deliver materials to construction sites, causing delays []. Similarly, unreliable power supplies disrupt the operation of equipment and machinery, slowing down progress []. Another major issue is the unavailability of advanced technological integration due to cost or expertise barriers. While advanced tools and systems can improve project planning, management, and execution, many construction firms in developing nations continue to rely on traditional methods. High costs, limited technical knowledge, and resistance to change hinder the adoption of modern technologies.
Quality management is another critical area that is often neglected. A lack of understanding about its importance leads to frequent errors during construction, many of which are only identified after project completion. These errors increase costs and, in severe cases, require structures to be rebuilt entirely [,,]. Poor quality control in the construction industry causes significant problems, increasing risks and wasting resources. Mismanagement often results in substandard structures that compromise safety and require costly rework. These quality issues arise from preventable errors, leading to unnecessary waste of time [,,], money, and raw materials [,].
This challenge is especially common in developing countries, where limited financial resources and a lack of technology hinder effective quality control and cause a shortage in the level of expertise available on-site. The risks go beyond individual projects, affecting society by reducing the quality of infrastructure and hindering sustainable development goals [,,]. These challenges, limited funding, inadequate infrastructure, insufficient technological integration, and poor-quality management negatively impact productivity, safety, and efficiency in the construction industry.
Funding limitations reduce the availability of expertise on-site, as well as material and labor quality; substandard infrastructure causes delays, and the lack of technology and quality management prevents the industry from achieving optimal efficiency and safety. This creates a substantial gap between the industry’s potential and its actual performance []. The gap widens as technological advancements remain underutilized [].
To address these issues, there is a clear need for cost-effective and easily deployable technological solutions that balance affordability and functionality. This study introduces an affordable, real-time, camera-based safety and quality management framework designed specifically for the construction industry in resource-limited environments. The proposed system uses affordable camera technology integrated with a structured web-based platform to systematically identify, document, and resolve safety and quality concerns. By focusing on affordability, scalability, and adaptability, the framework offers a practical solution that addresses the unique challenges of developing countries. The system aims to improve safety, reduce defects, and enhance project timelines to ultimately improve economic growth and support sustainable development. Finally, it is worth noting that there is no validation of the proposed system in quantitative terms, but rather the suitability and applicability of the proposed system was tested through the use of a case study in Iraq.
2. Literature Review
2.1. Traditional Quality Management Systems in Construction
Quality management in construction is a continuous process involving careful inspections, monitoring, and addressing any identified defects or irregularities []. Historically, this process has relied heavily on manual observations and professional evaluations, often requiring the presence of a skilled quality inspector on-site to assess the work. A standard practice in these inspections involves using a systematic checklist []. This checklist ensures that on-site work complies with established quality standards, promoting consistency and maintaining expected levels of quality.
Traditional quality management methods also involve extensive paper-based documentation. These records include quality plans, project standards, control measures, and notes on any detected discrepancies [,]. While commonly used, such systems have notable limitations. Manual inspections are time-intensive, labor-heavy, and susceptible to human error or subjective judgment []. This can lead to variability in quality assessments depending on the inspector. Paper documentation, while thorough, is vulnerable to loss, damage, or misplacement, making it difficult to retrieve records and track project progress. The absence of real-time reporting in traditional methods often delays defect rectification, extending timelines and increasing costs.
These challenges are even more pronounced in developing countries, where limited resources and insufficient training exacerbate the issues. Poor construction quality in such regions often leads to catastrophic structural failures, causing loss of life and significant property damage. Beyond immediate consequences, this results in recurring maintenance costs, placing financial strain on economies and undermining the long-term viability of infrastructure [].
The concept of safety management originated in the 1930s when Heinrich identified that most industrial accidents stemmed from unsafe actions rather than physical hazards. This understanding formed the basis for addressing both worker behavior and environmental risks []. Petersen expanded on Heinrich’s work, emphasizing the human element in occupational safety []. Research has linked successful safety programs to factors such as management commitment, employee relations, better training, improved work environments, and stable workforce practices []. These align with OSHA’s “Safety and Health Program Management Guidelines”, which emphasize leadership, employee participation, workplace analysis, hazard control, and training [].
Advancements in safety management have introduced perspectives such as behavioral safety [], safety culture [,], safety climate [], and human error theory []. Among these, behavior-based safety (BBS) has gained significant attention since the 1980s because of its effectiveness in accident prevention. BBS involves identifying unsafe behaviors, observing them over time, providing feedback to encourage safer practices, and sharing performance insights with the organization []. This method shifts safety performance indicators from lagging to leading measures, focusing on proactive strategies.
Proactive Comprehensive Management Systems (PCMSs) integrate advanced technologies to enhance communication and safety awareness on construction sites. These systems provide features such as position tracking, danger detection, safety training, and real-time hazard alerts. PCMSs include two primary components: the Real-Time Location System (RTLS) and the Virtual Construction Simulation System (VCS).
The RTLS relies on a wireless network that is compliant with the IEEE 802.15.4a standard [] for tracking objects in dense construction environments. It achieves location accuracy within one meter using trilateration methods. The RTLS manages location data, calculates positions, and sends danger alarms to workers through wearable tags.
The VCS provides real-time visualization of construction processes, tracking people and equipment in a virtual environment. It integrates a 3D model of the site, hazardous zones, and live object locations. When workers approach dangerous areas, the system triggers warning signals to their helmets. This functionality, supported by an intuitive user interface, helps supervisors monitor safety and generate reports remotely.
2.2. Evolution of Technological Integration in Construction Management
In recent years, the construction industry has experienced a significant shift, with technology becoming a central component of quality management practices []. This shift has largely been driven by advancements in digital technologies, which have transformed numerous sectors, including construction. The initial adoption of digital documentation served as a foundational step in this transformation, offering more efficient ways to manage and share project information []. Moving away from paper-based systems, the industry embraced digital document management systems, which streamlined operations and made data more accessible and organized.
As technology continued to advance, more complex solutions emerged, fundamentally changing the industry’s operational landscape. One notable innovation is Building Information Modeling (BIM), a 3D model-based process that enables professionals in architecture, engineering, and construction to design, plan, and manage projects more effectively [,]. BIM allows for virtual project visualization, reducing errors and enhancing precision during construction [,,,].
The Internet of Things (IoT) has further expanded technological capabilities in the construction industry [,]. Through internet-connected sensors, the IoT facilitates remote monitoring of project elements, such as inventory, equipment performance, and environmental conditions, which improves efficiency and quality management [,,]. Advanced sensors collect real-time data on various parameters, enabling rapid responses to potential issues and maintaining high construction standards [,].
These technological advancements have led to several benefits, including increased efficiency, improved accuracy, and better communication among project stakeholders. This fosters smoother collaboration and reduces misunderstandings, ultimately minimizing the risk of project failures. However, challenges remain. High implementation costs for advanced systems, along with the need for specialized training, can be barriers for smaller construction firms. Furthermore, as digital tools become more widespread, concerns about data privacy and security grow, with potential risks of breaches or unauthorized access posing legal and financial implications [].
Recent advancements in safety management within the construction industry include the application of machine learning techniques such as Grounded Theory (GT), Fuzzy Cognitive Maps (FCMs), and Grey Relational Analysis (GRA) []. GT is a qualitative research method that derives theory from qualitative data analysis, such as interviews. This method includes three main stages: open coding, axial coding, and selective coding []. Axial coding relates categories to subcategories, addressing contextual factors and processes that explain a phenomenon. Selective coding integrates the data into a coherent theory by identifying a central theme.
Another approach, Cognitive Maps (CMs), originally proposed, represents causal relationships graphically. Fuzzy Cognitive Maps (FCMs) were introduced to extend this concept by incorporating fuzzy logic to account for uncertainties in causal relationships []. FCMs combine principles from neural networks and fuzzy sets, making them versatile for applications in areas such as decision making, planning, and predictive modeling [].
2.3. Camera-Based Safety and Quality Management Systems for Developing Countries
In construction quality management, camera-based systems are becoming increasingly popular and reshaping the industry [,]. These systems rely on advanced digital imaging technology to improve the identification and correction of defects and non-compliance in construction projects [,]. At the core of these systems are high-resolution cameras capable of capturing detailed views of construction sites.
The visual data collected, whether as still images or video, offers a thorough perspective of the entire construction process, from minute structural components to broader site overviews [].
The integration of machine learning algorithms with digital imaging technology has significantly advanced construction quality management. These algorithms analyze the captured data to identify deviations from established quality standards []. The complexity of analysis can range from simple comparisons, such as color matching, to more advanced tasks like pattern recognition and anomaly detection [].
Research shows that camera-based systems enhance efficiency and effectiveness in quality management. A major advantage is real-time monitoring, enabling immediate detection and resolution of issues, which helps prevent delays and cost overruns []. These systems also reduce reliance on manual inspections, which are labor-intensive and prone to human error, thereby improving accuracy and saving time []. Additionally, digital records created by these systems support accountability and facilitate future analyses, contributing to continuous process improvement [].
However, adopting these systems involves challenges. Initial costs can be high due to sophisticated hardware, software, and maintenance requirements. Privacy concerns also arise, particularly in residential projects or areas with pedestrian activity, necessitating compliance with privacy laws. Furthermore, managing the large volumes of data generated requires robust infrastructure [,].
Cost barriers and technical capacity limitations are especially significant in developing countries. These regions often face financial constraints and a lack of skilled personnel to implement and maintain such systems [,]. Addressing these issues requires exploring affordable hardware, open-source software, and training programs to build local expertise.
Research should focus on identifying cost-effective solutions, optimizing open-source tools, and designing effective training initiatives. Such efforts could make camera-based systems more accessible and allow developing countries to benefit from improved quality management in construction. These advancements have the potential to enhance efficiency, safety, and quality globally, contributing to industry growth.
Safety is another critical aspect, particularly in preventing struck-by accidents. Traditional manual observations have limitations due to time and accuracy constraints []. Sensor-based methods, such as GPS, radar, and RFID systems, offer automated solutions for proximity monitoring [,]. However, these methods often involve high costs and logistical challenges, such as tagging equipment and workers [].
Computer vision-based techniques provide a promising alternative. These systems rely on object detection and tracking through cameras such as RGB-depth, stereo, or 2D RGB cameras. While RGB-depth cameras may face challenges in outdoor environments, stereo cameras and 2D RGB cameras are more commonly used in construction for surveillance and proximity detection []. Table 1 shows the brief review of camera-based safety and quality management systems for developing countries.
