(SEM IV) THEORY EXAMINATION 2024-25 UNIVERSAL HUMAN VALUES & PROFESSIONAL ETHICS

The uploaded document is the B.Tech Semester IV Theory Examination Paper (2024–25) for the subject BOE414 – Building Science and Engineering. This official examination paper is designed to evaluate a student’s understanding of the essential principles of building construction, building components, water supply and quality, earthquake-resistant construction techniques, sustainable building practices, and smart-city infrastructure. It carries 70 marks, the exam duration is 3 hours, and every question is provided in both English and Hindi, clearly visible on Page 1 and Page 2 of the document, making the paper accessible for students from all linguistic backgrounds.
 

The paper begins with Section A, a compulsory set of seven short-answer questions, each worth 2 marks, intended to test fundamental knowledge. The section asks students to list five essential components of a residential building—components that typically include foundation, plinth, walls, floors, roof, and openings such as doors and windows. It then requires definitions of foundation and plinth, along with their functions, ensuring clarity on the roles they play in load transfer and protection of the building structure. Students must mention two methods of energy conservation in buildings, demonstrating awareness of sustainable construction techniques such as proper orientation, insulation, shading devices, and efficient lighting systems. The paper proceeds by asking for four acceptable physical characteristics of potable water, highlighting parameters like clarity, odorlessness, colorlessness, and absence of suspended impurities. A key question in this section asks about the lintel band, an important earthquake-resistant feature provided in masonry buildings to improve structural integrity. The section also checks conceptual understanding of a smart city, requiring students to define it in their own words. Finally, it asks students to mention two modern applications used in urban water billing or property tax systems, referring to digital tools like GIS-based billing, online property tax portals, and automated metering.
 

Section B consists of five descriptive questions of 7 marks each, out of which students must attempt any three. This section requires explanations, sketches, reasons, and examples. The first question asks students to explain the roles of beams, columns, and slabs in framed structures using a simple sketch. This tests the student’s understanding of how loads are distributed from slabs to beams, then to columns, and finally to the foundation. Another question explores how building orientation helps reduce energy consumption by allowing maximum daylight, cross-ventilation, and reducing heat gain. The section also includes a question about the importance of fluoride and hardness levels in drinking water, emphasizing both public health and water-quality management. Another question asks how earthquake-resistant bands and vertical reinforcements help reduce structural damage in masonry buildings by improving ductility and ensuring better load transfer during seismic events. The final question in Section B requires a description of digital tools used in smart cities for public service management, such as digital grievance redressal systems, city surveillance networks, smart water metering, and online utility dashboards.
 

Section C, the final and analytical section of the paper, contains long-answer questions grouped into multiple subsections (Q3 to Q7), where students must choose one question from each group, with each question worth 7 marks. The first subsection (Q3) asks students to discuss common bathroom fittings used in urban housing—such as taps, mixers, showers, wash basins, and flushing systems—and explain their functions. The alternate question requires an explanation of how recycled waste materials such as fly ash, crushed concrete, plastic fibers, and recycled aggregates can be used in construction, promoting sustainability and reducing environmental impact.
 

The next subsection (Q4) includes a question comparing the GRIHA and IGBC green building rating systems, focusing on their features, sustainability goals, energy-efficiency parameters, and assessment methods. Alternatively, students may explain how window placement and room orientation can enhance daylighting and ventilation, reducing dependence on artificial lighting and mechanical ventilation systems.
 

In the subsection (Q5), students may be asked about bacteriological indicators of water quality, such as E. coli and coliform bacteria, and how these indicators help assess water safety. The alternative question covers the causes and prevention of waterborne diseases, requiring explanation of illnesses such as typhoid, cholera, or dysentery.
 

Subsection (Q6) deals with earthquake-resistant construction. One question requires describing general guidelines for making masonry houses earthquake-resistant, such as provision of plinth bands, lintel bands, corner reinforcements, and controlled size/position of openings. The alternate question requires a detailed explanation, with neat sketches, of gable bands and vertical reinforcements used in masonry walls for seismic strengthening.

The final subsection (Q7) focuses on smart-city technologies. One question asks students to explain the role of the Integrated Command and Control Centre (ICCC) in smart-city management, detailing how it centralizes real-time monitoring of traffic, water supply, waste management, emergency response, and city services. The alternative question deals with the role of GIS (Geographic Information System) and data analytics in enhancing smart-city infrastructure and urban services by enabling better planning, spatial mapping, predictive maintenance, and efficient decision-making.

Overall, the examination paper is a comprehensive and well-structured evaluation tool that covers traditional building science concepts, environmental considerations, public health engineering, structural safety, sustainable construction practices, and emerging smart-city technologies. With its bilingual formatting, combination of theoretical, descriptive, and analytical questions, and complete coverage of both foundational and modern concepts, the paper effectively assesses a student’s understanding of Building Science and Engineering in both academic and practical contexts.
