: Agile Project Management (APM) approaches are being adopted by the construction sector more often to deal with the complexity and uncertainty that come with large-scale projects. APM is a flexible, iterative method that places a focus on adaptability, continuous improvement, and consumer engagement. This essay examines the development of APM in the construction industry, emphasizing its core principles and benefits while contrasting it with traditional project management (TPM). The report also includes a case study of an infrastructure project for an Indian hospital that illustrates how APM may decrease delays and increase stakeholder satisfaction. The study concludes by outlining the main success factors and difficulties of applying APM in the construction sector and arguing that APM has the ability to completely reshape project management methods worldwide.

: Bio-mimicry is the emulation of nature’s design principles and strategies. It revolutionizes the field of structural engineering by offering innovative solutions that are efficient, sustainable, adaptable and aesthetically pleasing. The aim is to dive into the realm of biomimicry in structural design, specifically focusing on its potential applications, challenges, sustainability and efficiency within the unique context of Bangladesh. Through careful examination, several remarkable biomimetic strategies have been unveiled, including but not limited to the application of fractal geometries for enhanced structural efficiency, inspired from natural forms for increased load-bearing capacity, and the utilization of self-healing mechanisms for improved durability. They offer prospective solutions to address difficulties particular to Bangladesh, such as minimizing the impacts of regular monsoons, guaranteeing resilience against seismic activity, and optimizing material consumption in resource constrained regions. However, this research also emphasizes the limitations associated with turning bio-mimetic concepts practical considerations. The cultural, economic, and regulatory features of Bangladesh represent distinct challenges that must be negotiated to enable successful adoption. Furthermore, the shortage of locally relevant bio-mimetic research and knowledge needs a joint approach, encompassing academia, business, and government authorities. In conclusion, this analysis sheds light on the untapped potential of bio-mimicry in changing structural design methods inside Bangladesh. By implementing cutting-edge bio-mimetic concepts with the country’s particular difficulties and potential, a route emerges toward innovative and sustainable structural solutions that harmonize with both nature and society. This study intends to promote more research, dialogue, and collaboration in the dynamic sector of bio-mimicry and structural engineering, with the ultimate goal of fostering resilient, ecologically sensitive constructed environments in Bangladesh.

: This research studies the prospective of integrating waste polyethylene terephthalate (PET) powder as a limited replacement of sand in steel fiber reinforced concrete (SFRC). The elementary purpose is to develop an ecologically friendly concrete with improved mechanical properties. The study explores the effects of varying WPET powder dosages (3%, 5%, and 7%) and steel fiber contents (1.5% and 2%) on the mechanical properties of SFRC. Results are also analyzed to determine the PET-aggregate’s and steel fiber’s effects on the relationship between the compressive, flexural and splitting tensile strengths to know whether the strength characteristics comply with the given strengths in ASTM and ACI design codes and are applicable to concrete made with PET-aggregates and steel fibers. According to our findings, the compressive strength increased up to 5% PET aggregate and 2% steel fiber incorporation but decreased for further increment in PET percentage. Similar characteristics were found for splitting and flexural strengths for the implemented PET and steel fiber percentages. However, this research aims to contribute to the development of sustainable construction materials through possible optimum application by mitigating the environmental impact of waste plastic and reducing the reliance on virgin sand resources. The findings provided valuable insights into the feasibility of utilizing WPET powder as a viable alternative in SFRC production while contributing to the development of concrete being sustainable and showing high-performance.

: Increased population leads to increased use of materials that, if not properly disposed of, pollute the environment. One of the best construction engineering strategies is to replace expensive building materials with disposable waste resources. Pozzolanic materials, glass powder, and silica fume (SF) have all lately been utilized in concrete as partial fine aggregate/cement substitutions to improve its strength. This study explores the development of an environmentally conscious and cost-effective hybrid concrete solution by integrating waste glass powder and silica fume into the mix. In the initial phase, 20 concrete cylinder molds were made using recycled aggregates, cement, sand, and waste glass powder. The sand content was partially replaced with waste glass powder at varying percentages (0%, 5%, 10%, 15%, and 20%). Subsequently, another set of 20 molds was created with recycled aggregates, cement, sand, and silica fume, omitting waste glass powder. Cement content was partially replaced with silica fume at percentages of 10%, 15%, 20%, and 30%. Tensile and compressive strength tests were conducted on both sets of experiments after 7 and 28 days of curing, along with the determination of flexural strength in concrete beams after 28 days. The results indicated varying strength characteristics based on the replacement percentages of waste glass powder and silica fume. Following the analysis, a hybrid concrete mold was formulated by identifying the optimum strength parameters—10% replacement of sand with waste glass powder and 20% replacement of cement with silica fume. This hybrid solution comprised recycled aggregates, cement, sand, waste glass powder (10% replacement for sand), and silica fume (20% replacement for cement). The synthesis of this hybrid concrete aimed to achieve a balance between optimum strength, cost-effectiveness, and environmental sustainability. The findings of this research contribute to the advancement of sustainable concrete practices, providing insights into the synergistic effects of waste glass powder and silica fume in hybrid mixtures. The developed hybrid concrete presents a promising avenue for reducing environmental impact while maintaining structural integrity and cost efficiency in construction projects.

: This research investigates the integration of Augmented Reality (AR) and BIM for enhanced construction design validation and clash detection. Leveraging Revit, Tekla Structures, Navisworks, and Unity, we are working on to develop a workflow that enables immersive visualization of structural models within AR/VR environments. The study focuses on detecting and resolving clashes between structural components of a multi-storied residential building, offering an interactive platform for pre-construction visualization for stakeholders to validate designs. This approach is expected to improve design coordination, error reduction, and improve project efficiency, while minimizing rework and misspend costs during the construction phase. The research highlights how AR/VR simulation can transform traditional workflows, ensuring more accurate decision-making and seamless collaboration across project teams.
