Abstract: The economy of all structures is being impacted by the current cost of building materials. It has a significant impact on the global environmental housing system. Conventional aggregates, such as gravel, and fine aggregate, such as sand in concrete, will be utilized for control. Robo sand (stone dust) will be used as fine aggregate to replace the sand in concrete, while natural material such as coconut shell will be researched as a coarse aggregate. In this study, sample specimens are prepared and tested using M25 grade concrete that has a combination of natural material coconut shell content as coarse aggregate in the proportions of 0%, 5%, 10%, 15%, 20%, and 25%, and Robo sand (stone dust) as fine aggregate with a complete 100% replacement of natural sand. for workability, compressive strength, split tensile strength and flexural strength for 7,14 and 28 days respectively and also showing the comparative results with Conventional M25 grade concrete. By this project investigation, concrete may be less dense, light weight concrete by coconut shells and good quality of concrete by Robo sand.

Abstract: Building Information Modeling (BIM) has emerged as a transformative digital technology in the construction industry by enabling intelligent 3D modeling, improved collaboration, and efficient information management throughout the project lifecycle. However, successful project execution not only depends on accurate design representation but also requires effective project planning, scheduling, and resource control. Primavera P6 is widely recognized as a powerful project management software that supports detailed planning, time scheduling, cost estimation, and progress monitoring for complex construction projects. The integration of BIM with Primavera provides a highly efficient platform for developing realistic construction schedules, improving project visualization, and ensuring better decision-making during project execution.This study focuses on BIM-integrated project planning and scheduling using Primavera to enhance the effectiveness of construction project management. BIM models developed using software such as Revit are linked with Primavera schedules to establish a strong relationship between project activities and building components. This integration supports 4D planning, where the time dimension is combined with the 3D model to simulate construction sequencing and visualize the progress of project execution. Through BIM-based scheduling, construction stakeholders can identify logical activity sequences, detect clashes in time and space, and optimize the use of labor, materials, and equipment. The integrated approach improves coordination between architects, engineers, contractors, and project managers, thereby minimizing scheduling conflicts, reducing rework, and improving productivity.

Abstract: Understanding the behaviour of bolstered concrete is vital for properly predicting future earthquake loading consequences on reinforced concrete systems and designing the structural gadget to undergo seismic pressures. Accurate seismic load consequences on the structural device are vital no longer just in multi-story buildings but additionally in usual residential constructions. This research examines the results of slab kinds at the performance of load-bearing systems in multi-tale reinforced concrete systems underneath seismic hundreds, in accordance with the modern-day Turkish Earthquake Code (TEC). This research conducts a comparative analysis of a flat slab gadget with 4 beam versions for a seven-story structure. The examine is conducted with pushover evaluation with the assistance of the ETABS software program application. The beam variations are labeled as follows: a structure with a completely flat slab (no beams), a shape with a flat slab and perimeter beams (apart from indoors beams), a shape with a flat slab and all beams, and a structure with a flat slab, whole beams, and brick walls. The examine findings, including base shear, storey drift, time period, and frequency, are tested for the G+8 building model.

Abstract: The disposal of waste tyres has emerged as a significant environmental challenge due to their non-biodegradable nature, large volume generation, and associated fire and health hazards. In the context of sustainable infrastructure development, the utilization of waste tyre rubber in pavement base and sub-base layers presents a promising alternative for both waste management and performance enhancement of flexible pavements. This study investigates the feasibility, engineering behavior, and structural performance of pavement base and sub-base materials modified with waste tyre rubber in various forms such as shredded rubber, crumb rubber, and rubber chips. Laboratory experimental investigations were conducted to evaluate key geotechnical and mechanical properties including compaction characteristics, California Bearing Ratio (CBR), unconfined compressive strength (UCS), resilient modulus, permeability, and durability. The influence of rubber content on density, stiffness, deformation characteristics, and energy absorption capacity was systematically analyzed. Results indicate that controlled incorporation of waste tyre rubber improves ductility, fatigue resistance, and resistance to cracking while contributing to reduction in material brittleness. However, excessive rubber content leads to reduction in load-bearing capacity due to lower stiffness and density. The study identifies optimum rubber content ranges suitable for base and sub-base applications based on performance criteria. Environmental and economic benefits, including reduced landfill burden, conservation of natural aggregates, and lifecycle cost savings, are also discussed. The findings support the potential of waste tyre rubber as a sustainable geomaterial for pavement applications, contributing to circular economy principles and resilient road infrastructure.

Abstract: Sustainable pavement design has gained significant attention due to the increasing scarcity of natural aggregates and the environmental burden associated with construction activities. Construction and Demolition (C&D) waste offers a viable alternative material for pavement layers, promoting resource conservation and circular economy principles. This study investigates the feasibility of utilizing processed C&D waste in flexible pavement construction with an emphasis on structural performance, durability, and sustainability. The engineering properties of C&D waste aggregates, including gradation, strength, and stiffness characteristics, are evaluated and compared with conventional materials. Mechanistic–empirical design concepts are adopted to assess pavement response and long-term performance. Non-destructive evaluation techniques are considered to monitor in-service behavior and structural integrity of pavements incorporating recycled materials. Results indicate that, with proper processing and mix design, C&D waste can satisfactorily meet pavement design requirements. The use of C&D waste significantly reduces material costs, landfill disposal, and carbon footprint. This approach supports sustainable infrastructure development while maintaining acceptable performance standards. The findings provide practical guidance for integrating recycled materials into pavement design frameworks.

Abstract: In present day multi-tale structures in urban India, floating columns are a ordinary architectural function. Such functionalities need to not be universally used in systems constructed in seismically lively regions. This remark underscores the importance of figuring out the floating column in structural evaluation. We provide an change method for mitigating the unpredictable behaviour of floating columns. Achieving equilibrium between the principle and superior floors's stiffness is critical to this method. The hazards associated with inadequately constructed edifices and the destruction because of earthquakes are stark realities in several regions worldwide. Floating columns are a exclusive characteristic in numerous present day multi-story structures in India's predominant towns. The floating column exemplifies a vertical element supported by means of a beam at its base. To mitigate the risky inertia forces produced at various floor levels of a large shape, the burden transfer mechanism ought to be directed from the pinnacle to the lowest. Any departure or divergence from this channel will result in poor overall performance. Floating columns need to no longer be used within the design of systems located in seismically active areas. The donation research take a look at the unfavorable outcomes of the building's floating columns. This studies used body fashions to study the effect of unstable excitation on several structural traits in multi-story strengthened concrete systems, inclusive of herbal frequency, base shear, and horizontal displacement. The constructions are in comparison with and with out floating columns.The modern-day observe used ETABS 2018 for seismic evaluation and the layout of floating multi-tale buildings. This examination covers both inner and outside floating. To take a look at the effects on story go with the flow, shear pressure, bending moment, and structural torsion, we compared G+10 models with and with out floating columns.

Abstract: Concrete is the most widely used construction material; however, its inherent brittleness and low tensile strength limit its performance under dynamic loading conditions such as impact and fatigue. Structures including pavements, bridge decks, industrial floors, airport runways, and protective structures are frequently subjected to repeated cyclic loads and sudden impact forces, which can lead to progressive cracking, stiffness degradation, and premature failure in conventional concrete. To overcome these limitations, Fiber Reinforced Concrete (FRC) has emerged as an effective composite material that enhances the mechanical performance and durability of concrete under extreme loading conditions. Fiber Reinforced Concrete is produced by incorporating discrete fibers such as steel, polypropylene, glass, carbon, or natural fibers into the concrete matrix. These fibers act as crack arresters by bridging microcracks and restraining their propagation, thereby improving toughness, ductility, and post-cracking behavior. Under impact loading, the presence of fibers significantly increases the energy absorption capacity of concrete, delays crack initiation, and transforms brittle failure into a more ductile mode. Experimental studies have shown that FRC exhibits substantially higher impact resistance compared to conventional concrete, with improvements strongly influenced by fiber type, aspect ratio, volume fraction, and orientation. Under fatigue loading, Fiber Reinforced Concrete demonstrates superior performance by enhancing fatigue life and reducing the rate of crack growth under repeated stress cycles. Fibers help redistribute stresses across the cracked sections and maintain structural integrity even after matrix cracking. Steel fiber reinforced concrete, in particular, has been shown to exhibit excellent fatigue resistance, while synthetic fibers contribute to improved durability and crack control. The synergistic use of hybrid fiber systems further enhances fatigue performance by combining strength and ductility characteristics. Overall, the incorporation of fibers significantly improves the resistance of concrete to impact and fatigue loading, making Fiber Reinforced Concrete a promising material for applications subjected to dynamic and cyclic loads. The improved mechanical performance, enhanced durability, and extended service life of FRC contribute to safer, more resilient, and sustainable infrastructure. Continued research on optimized fiber combinations, numerical modeling, and long-term field performance is essential for wider adoption of Fiber Reinforced Concrete in modern construction practices.

Abstract: The layout planning is a part of urban development it includes planning of residential houses, commercial complexes, service roads, primary health centers, school…& other amenities sewerage system for whole layout (includes treatment, sewer line, storm water drains), water distribution system. This project includes design& estimation of residential building in plot of layout planned. Designing involves identifying the loads which act upon a structure and the forces and stresses which arise within that structure due to those loads, perform analysis to get moments and shear forces on different elements of the structure and then design the structure for ultimate loads and moments. The loads can be self-weight of the structures, other dead loads, live loads, moving (wheel) loads, wind load, earthquake load, load from temperature change etc. Estimation includes finding the quantities of materials required for the construction of the structure and requirements of labor etc., finally determining the overall cost of the structure before execution of work by using Auto cad. Structural engineers are facing the challenge of striving for the most efficient and economical design with accuracy in solution, while ensuring that the final design of a building must be serviceable for its intended function over its design lifetime. This project attempts to understand the structural behavior of various components in the multi-storied building. Analysis, designing and estimation of multi-storied building has been taken up for Basement+G+2 Building, thereby depending on the suitability of plan, layout of beams and positions of columns are fixed. Dead loads are calculated based on material properties and live loads are considered according to the code IS875-part 2, footings are designed based on safe bearing capacity of soil. For the design of columns and beams frame analysis is done by limit state method to know the moments they are acted upon. Slab designing is done depending upon the type of slab (one way or two way), end conditions and the loading. From the slabs the loads are transferred to the beams, thereafter the loads from the beams are taken up by the columns and then to footing finally the section is checked for the components manually and for the post analysis of structure, maximum shear force, bending moment and maximum story displacement are computed. The quantitative estimation has been worked out. All the drafting was done using Auto cad.

Abstract: Traffic congestion has become a serious issue in rapidly growing cities, causing delays, increased fuel usage, and environmental damage. Traditional traffic systems rely on fixed signals and limited data, making them ineffective in handling real-time traffic variations. To overcome these limitations, this study introduces a smart traffic prediction system that combines Artificial Intelligence (AI) and the Internet of Things (IoT). The system gathers real-time data from devices such as traffic cameras, GPS trackers, and roadside sensors. This data is then analyzed using machine learning models, especially Long Short-Term Memory (LSTM), to predict future traffic conditions. The goal of this system is to improve traffic flow, reduce congestion, and support better decision-making for traffic authorities. With the help of cloud computing, the system can efficiently handle large amounts of data. Experimental results show that this approach performs better than traditional methods by improving prediction accuracy and reducing delays. Overall, this system contributes to smarter cities and better quality of life.
