<p>1. Site Execution Work in RCC of Commercial Building<br>During the internship, I was actively involved in on-site execution activities related to Reinforced Cement Concrete (RCC) construction for a commercial building. This included:<br>â— Supervising daily site activities such as formwork installation, reinforcement placement, and concreting.<br>Ensuring proper alignment, level, and dimensions as per design specifications.<br>â— Coordinating with contractors, laborers, and engineers to maintain workflow efficiency.<br>â—Observing quality control practices and safety measures followed on site.<br>2. Study of Architectural and Structural Drawings<br>â—I developed the ability to read and interpret both architectural and --&nbsp; structural drawings:<br>Architectural Drawings:<br>â—Learned layout planning, room dimensions, elevations, and sections.<br>Understood spatial arrangements, aesthetics, and functional design.<br>Structural Drawings:<br>â—Studied structural components like beams, columns, slabs, and footings.<br>Interpreted reinforcement details, bar bending schedules (BBS), and load transfer mechanisms.<br>â—Gained knowledge of how design translates into actual construction.<br>3. Steel Detailing in Columns and Slabs<br>A major part of my learning involved reinforcement detailing:<br>â—Columns:<br>Studied longitudinal bars and lateral ties (stirrups).<br>Understood spacing, diameter, and anchorage of reinforcement.<br>â—Learned about lap length and proper placement techniques.<br>Slabs:<br>â—Observed main reinforcement and distribution steel placement.<br>Understood cover requirements and spacing between bars.<br>Learned how reinforcement resists bending and distributes loads.<br>4. Post-Tension (PT) Slab System<br>I gained exposure to Post-Tensioned (PT) slab technology, which is widely used in commercial buildings:<br>Learned how tendons (high-strength steel cables) are placed within the slab before concreting.<br>â—After concrete gains strength, tendons are stressed using hydraulic jacks, applying pressure.<br>â—This process introduces compressive forces in the slab, improving its strength and performance.<br>Benefits observed:<br>Reduced slab thickness<br>Longer spans without beams<br>Better crack resistance and durability<br>5. Concreting Procedure and Grades of Concrete<br>â—I studied the complete concreting process:<br>Preparation:<br>Checking formwork, reinforcement, and cleanliness before pouring concrete.<br>â—Concrete Grades:<br>Understood different grades like M20, M25, etc., based on strength requirements.<br>â—Learned mix proportions and their applications in different structural elements.<br>â—Pouring &amp; Compaction:<br>Observed proper placement of concrete.<br>â—Use of vibrators to remove air voids and ensure compaction.<br>â—Finishing &amp; Curing:<br>Surface finishing techniques for slabs.<br>Importance of curing (water curing) to achieve required strength and durab</p>
