Introduction
Bangladesh, a country susceptible to a myriad of hazards including earthquakes, floods, and windstorms, has recognized the critical role that safe building codes play in disaster resilience (Sarkar, 2018)[1]. This awareness becomes particularly pivotal in the aftermath of catastrophic events like the Rana Plaza building collapse, underscoring the urgency of effective building code enforcement (Dey, S., & Basak, P., 2016)[2]. Unlike their counterparts in developed nations, Bangladesh faces challenges in seamlessly integrating building codes into regulations, especially within the informal building sector where limitations in affordability and access to codes persist (HBRI, 2015)[3].
In response to these challenges, the government initiated the “National Hackathon on Frontier Technologies” (TBS News, 2023)[4]. Spearheaded by the Innovation Design and Entrepreneurship Academy (iDEA) project under the ICT Division, this competition aimed to harness the ingenuity of the nation’s innovators. The overarching goal was to derive citizen-centric solutions to address the ten most pressing challenges faced by Bangladesh, with a focal point on the construction sector.
Government’s Role: Identifying Challenges and Organizing the Hackathon
The government’s proactive stance in organizing the hackathon underscores its commitment to overcoming challenges within the construction sector. The competition served as a platform for 51 teams, comprising approximately 150 innovators, to present novel perspectives and cutting-edge technologies. From a pool of 349 innovative solutions, the top teams were selected, showcasing the government’s dedication to leveraging the nation’s brightest minds.
Emergence of Innovative Solutions: Identifying Challenges and Crafting Responses
Within the hackathon participants, a standout team exemplifies the potential impact of this innovation-driven initiative. Comprising skilled professionals in architecture and engineering, this team directed their efforts toward addressing technical complexities inherent in construction code violations. They pinpointed the core problem hindering sustainable development as the absence of real-time monitoring and deviations from approved building designs.
The team’s proposed solution, termed the “Real-Time Building Construction Monitoring System,” harnesses machine learning algorithms, big data analysis, and experiments on classified data. This holistic approach aims not only to streamline the approval process but also to enhance monitoring capabilities and ensure strict compliance with regulations. Their vision seamlessly aligns with the government’s commitment to revolutionize the construction industry in Bangladesh, specifically targeting challenges related to land use clearance verification, architectural design approvals, and coordination complexities within the Rajdhani Unnayan Kartripakkha (RAJUK)[5].

Identification and Critical Analysis of the Core Problem
Sustainable Development Challenges in Bangladesh
Bangladesh confronts formidable challenges in the pursuit of sustainable development, compounded by the looming specter of climate change that disproportionately affects South and Southeast Asia (Sarkar, 2018). In the urban epicenter of Dhaka, where the population surpasses 20 million, the imperative for sustainable urban development intensifies. The unbridled pace of urbanization, however, poses a multifaceted risk spectrum, encompassing seismic vulnerabilities, fire hazards, and structural fragility. This demands the establishment of a robust framework to fortify urban safety and resilience, especially in the face of evolving climatic uncertainties (Dey & Basak, 2016). The intricate interplay of urbanization, demographic dynamics, and environmental considerations underscores the necessity for innovative strategies that harmonize development goals with environmental stewardship.
RAJUK’s Role and Challenges
The Rajdhani Unnayan Kartripakkha (RAJUK) emerged as a linchpin in shaping Dhaka’s intricate urban infrastructure. Despite its pivotal role, RAJUK grapples with substantial challenges in the effective enforcement of building codes and regulations. The labyrinthine process of obtaining building construction permits becomes a focal point, riddled with complexities such as fraudulent documentation and deviations from approved plans. This necessitates a paradigm shift towards innovative solutions that align the trajectory of urbanization with imperatives of safety, compliance, and sustainable development (HBRI, 2015). The suggestion of incorporating a QR Code for occupancy certificate verification underscores the pivotal role of technological interventions in enhancing transparency, streamlining regulatory processes, and fortifying accountability structures within the urban development landscape (Choudhury). RAJUK’s challenges thus catalyze a call for transformative approaches that navigate the delicate balance between regulatory stringency and facilitation of urban development.
Real-Time Construction Monitoring Necessity
The imperative for real-time construction monitoring crystallizes as a linchpin in addressing critical lacunae within the prevailing system. The conventional approval process, while comprehensive in design, grapples with inherent limitations in effectively monitoring deviations during the construction phase. Real-time monitoring emerges as an indispensable tool, acting proactively to rectify issues and ensuring seamless alignment with approved designs and building codes. This approach stands as a bulwark for risk mitigation, offering a dynamic response mechanism that reduces delays and augments overall efficiency in the construction sector. The integration of real-time data analytics, machine learning, and monitoring technologies becomes imperative for ushering in an era of construction practices characterized by precision, compliance, and adaptability to evolving urban dynamics.
The use of real-time monitoring and data analytics can revolutionize the way we design, construct, and maintain buildings.
