Subhead 10.0 covers the specifications and requirements for various types of steel work in construction. Below is a detailed explanation of each section along with examples.
Steel work involves the use of steel for structural and non-structural elements in construction. This includes fabrication, welding, and installation of steel components.
Example: Installing steel beams and columns in a commercial building to provide structural support.
10.1.1 Steel: Steel should conform to specified standards such as IS 2062 for mild steel and IS 8500 for high tensile steel.
10.1.2 Bolts, Nuts, and Washers: Should conform to IS 1363 and IS 1367.
10.1.3 Electrodes: Should conform to IS 814 for manual metal arc welding.
Example: Using high tensile steel for constructing a bridge to ensure it can withstand heavy loads.
10.2.1 Fabrication: Steel components should be fabricated as per design specifications. This includes cutting, drilling, welding, and assembly.
10.2.2 Welding: Welding should be done by certified welders using appropriate electrodes. Welds should be inspected and tested for quality.
10.2.3 Erection: Steel components should be erected as per the design drawings. Temporary supports should be provided during erection.
Example: Fabricating and erecting steel frames for an industrial warehouse.
10.3.1 General: Steel doors and windows should be fabricated as per specified standards.
10.3.2 Frames: Frames should be made from specified sections, free from defects, and properly welded.
10.3.3 Shutters: Shutters should be made from specified sections, with proper joints and reinforcements.
10.3.4 Fittings: Fittings such as hinges, handles, and locks should be of specified quality and securely fixed.
Example: Installing steel doors and windows in a commercial building for security and durability.
10.4.1 General: Steel grills and railings should be fabricated as per design specifications.
10.4.2 Design: Grills and railings should be designed to ensure safety and aesthetic appeal.
10.4.3 Fixing: Grills and railings should be securely fixed to the structure using appropriate methods.
Example: Installing decorative steel grills and railings in a residential building for added security and aesthetics.
10.5.1 General: Stainless steel work should be fabricated and installed as per design specifications.
10.5.2 Grades: Stainless steel should conform to specified grades such as 304 and 316 for different applications.
10.5.3 Finishing: Stainless steel surfaces should be properly finished to prevent corrosion and enhance appearance.
Example: Using stainless steel for handrails and balustrades in a high-end residential project for durability and a sleek look.
10.6.1 General: Steel gates should be fabricated as per design specifications.
10.6.2 Design: Gates should be designed for strength, security, and ease of operation.
10.6.3 Fittings: Fittings such as hinges, latches, and locks should be of specified quality and securely fixed.
Example: Installing a steel gate at the entrance of an industrial complex for security and durability.
10.7.1 General: Steel trusses should be designed and fabricated as per specified standards.
10.7.2 Fabrication: Trusses should be fabricated with precision, ensuring all joints are properly welded and aligned.
10.7.3 Erection: Trusses should be erected with temporary supports until the structure is stable.
Example: Using steel trusses for the roof of a large-span warehouse to provide support and stability.
10.8.1 Surface Preparation: Steel surfaces should be cleaned of rust, scale, and other contaminants before painting.
10.8.2 Priming: A coat of primer should be applied to prepared surfaces to prevent corrosion.
10.8.3 Finishing Coats: Finishing coats should be applied as per specified standards, ensuring a uniform and durable finish.
Example: Applying anti-corrosive paint to steel structures in a coastal area to protect against saltwater corrosion.
10.9.1 General: Includes various steel components such as ladders, handrails, and brackets.
10.9.2 Fabrication and Fixing: Components should be fabricated and fixed as per design specifications.
Example: Installing steel ladders and handrails in an industrial facility for safety and accessibility.
