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