(SEM IV) THEORY EXAMINATION 2024-25 BUILDING SCIENCE AND ENGINEERING

The uploaded document is the B.Tech Semester IV Theory Examination Paper (2024–25) for the subject BOE414 – Building Science and Engineering. It is an official university examination paper created to evaluate a student’s understanding of foundational building components, construction technology, water supply systems, earthquake-resistant construction, sustainable design principles, and smart-city infrastructure. The exam carries 70 marks, has a duration of 3 hours, and is presented in a fully bilingual format — English and Hindi — as clearly visible on Page 1 and Page 2 of the document. This bilingual presentation ensures that students from different language backgrounds can interpret the questions with ease.

The examination begins with Section A, which contains seven compulsory short-answer questions, each worth 2 marks. These questions aim to test the student’s basic understanding of elementary building science concepts. Students must list essential components of a residential building, which typically include foundation, plinth, walls, floors, roofs, doors, and windows. They must define the terms foundation and plinth along with their functions, establishing their understanding of the load transfer mechanism in buildings. Another question requires students to mention methods for energy conservation in buildings, which emphasizes building orientation, natural lighting, ventilation, thermal insulation, and efficient electrical fixtures. Students are also asked to list acceptable physical characteristics of potable water, such as clarity, color, odor, taste, and absence of suspended solids. Further, the section asks for the purpose of a lintel band in masonry structures — a crucial component that helps distribute loads and enhances earthquake safety. The section concludes with questions related to defining a smart city in simple terms and naming modern digital applications used for urban water billing or property tax management, reflecting contemporary technology integration in civic systems. Section A ensures that students possess fundamental conceptual awareness before progressing to more complex topics.

Section B contains five descriptive questions, out of which students must attempt any three, each carrying 7 marks. These questions demand descriptive explanations and often require sketches or examples. One question asks for the roles of beams, columns, and slabs in framed structures, requiring a student to explain how loads are transferred from slabs to beams and then to columns and foundations. Another question focuses on building orientation and how it reduces energy consumption by maximizing natural light, ventilation, and thermal comfort. Students are also asked to explain why maintaining appropriate fluoride and hardness levels in drinking water is important for public health and water quality. Section B further includes questions on the role of earthquake-resistant bands and vertical reinforcements in minimizing damage to masonry structures during seismic events, highlighting the engineering principles of ductility and load redistribution. Another optional question in this section requires students to describe digital tools used in smart cities, such as GIS mapping systems, online grievance portals, e-governance apps, and automated public service dashboards. This section evaluates the student’s descriptive ability and understanding of applied engineering concepts in real-world scenarios.

Section C consists of the long-answer analytical questions divided into multiple subsections (Q3 to Q7). In each subsection, students must attempt one question, with each question carrying 7 marks. These questions assess higher-order thinking, technical understanding, and problem-solving ability. The first part (Q3) requires students to discuss common bathroom fittings used in urban housing such as taps, mixers, showers, flush systems, wash basins, and water closets, including their functions and relevance in modern sanitation. Alternatively, students may answer a question on how recycled waste materials like fly ash, crushed glass, plastic fibers, and construction debris can be used in building construction, promoting sustainability and cost-effectiveness.

The next subsection (Q4) asks students to compare GRIHA and IGBC green building rating systems in India, focusing on their features, sustainability goals, assessment criteria, and rating processes. Alternatively, they may explain how proper window placement and room orientation promote daylighting and natural ventilation, resulting in reduced electricity consumption and improved indoor comfort.

The following subsection (Q5) covers public health engineering topics, where students may be asked to describe bacteriological indicators of water quality, such as E. coli and coliform organisms, and explain their role in determining water safety. The alternative question requires students to explain the causes and prevention of waterborne diseases, discussing diseases such as cholera, typhoid, and hepatitis, along with sanitation practices and preventive methods.

Subsection (Q6) shifts toward earthquake engineering. Students may describe general guidelines for making masonry houses earthquake-resistant, including the use of seismic bands, corner strengthening, proper bonding in walls, controlled openings, and quality mortar. Alternatively, they must explain gable bands and vertical reinforcements in masonry walls using neat sketches, demonstrating their understanding of seismic load distribution and structural strengthening.

The final subsection (Q7) focuses on smart-city technologies. One question asks students to explain how the Integrated Command and Control Centre (ICCC) helps in smart-city management by integrating data from multiple departments such as traffic, water supply, waste management, street lighting, and emergency services. The alternative question requires explaining the role of GIS and data analytics in improving smart-city infrastructure and services, such as mapping utilities, managing assets, planning roads, and responding to citizen needs in real time.

Overall, this question paper provides a complete and comprehensive assessment of the subject Building Science and Engineering. It evaluates fundamental building concepts, structural behavior, water quality standards, earthquake-resistant design, sustainable construction practices, and emerging smart-city technologies. Through clearly structured sections, bilingual formatting, and a blend of conceptual, descriptive, and analytical questions, the paper ensures a holistic evaluation of a student’s understanding of both traditional and modern aspects of building engineering.
