Erection
Erection in construction and engineering refers to the process of assembling and installing structural components at the project site to create the intended structure. This term is commonly associated with the installation of steel frameworks, precast concrete components, or large machinery used in buildings, bridges, industrial facilities, and other infrastructure projects.
Key Aspects of Erection​
Preparation
- Site inspection and preparation to ensure it meets design and safety requirements.
- Delivery and staging of structural components.
Assembly
- Components are lifted, positioned, and aligned using cranes, hoists, or other lifting equipment.
- Connection techniques like welding, bolting, or riveting are used to secure elements together.
Stability and Alignment
- Temporary supports (like scaffolding or braces) may be used to maintain stability during the process.
- Precision tools ensure proper alignment and leveling of components.
Safety
Workers use safety gear and follow strict protocols to prevent accidents during lifting, handling, and assembly.
Inspection
Structural integrity and compliance with design specifications are checked before proceeding to the next phase of construction.
Applications of Erection
Building Construction
Installing steel or concrete frameworks for skyscrapers and factories.
Bridge Construction
Placing girders, trusses, and other components together for structural construction.
Industrial Projects
Setting up equipment, pipelines, or large-scale structures like power plants.
Towers and Masts
Installing communication towers, wind turbines, and similar vertical structures.
Erection is a critical phase in construction that transforms prefabricated or pre-assembled components into functional, on-site structures.
