METALLIC STRUCTURAL REVAMP ENGINEERING; PROCUREMENT; CONSTRUCTION; INSTALLATION & COMMISSIONING (EPCIC
Structural Assessment and Analysis:
- Condition Survey: Carryout detailed inspection of the existing metalwork, identifying areas of corrosion, cracks, deformations, missing components, or inadequate connections. This often involves non-destructive testing (NDT) methods.
- Structural Analysis: Performs engineering analysis to determine the current load-bearing capacity and identify areas that require strengthening or modification based on intended future use and current standards.
- Material Testing: Analysis of the existing steel’s properties to ensure it’s suitable for modifications and to determine the best approach for welding or bolting new components.
Design and Engineering:
- Concept Design: Developing preliminary plans for the revamp, outlining the scope of work and desired outcomes.
- Detailed Engineering: Creating precise structural drawings, calculations, and specifications for all new or modified metallic elements. This includes selecting appropriate steel grades, connection types (welding, bolting), and corrosion protection systems.
- Foundation Review: Assessing the existing foundations to ensure they can support any increased loads from the revamped structure.
Procurement and Fabrication:
- Material Sourcing: Procuring all necessary materials, including steel, bolts, welding consumables, and coatings. Given your location, considering local sourcing and quality is important.
- New Steelwork Fabrication: Procuring new steel beams, columns, trusses, plates, and other components according to the detailed designs.
Construction and Installation:
- Demolition/Dismantling (Selective): Carefully removing existing damaged or obsolete metallic elements.
- Structural Strengthening: This can involve:
- Adding new members: Bolting or welding new beams, columns, or bracing.
- Plate strengthening: Adding steel plates to existing members to increase their cross-sectional area and strength.
- Casing/Encasing: Using concrete or other materials to enhance the load-bearing capacity and fire resistance of steel members.
- Replacing components: Swapping out severely corroded or damaged elements.
- Welding and Bolting: Executing connections with precision and quality control to ensure structural integrity.
- Corrosion Protection: Applying protective coatings (paint, galvanization, fireproofing) to new and existing metalwork to prevent future corrosion and enhance durability.
- Erection: Installing new and reinforced metallic components
Quality Control and Testing:
- Regular Inspections: Throughout the fabrication and construction phases, strict quality control measures are implemented to ensure adherence to design specifications and industry standards based on agreed client procedure.
- Non-Destructive Testing (NDT): Methods like ultrasonic testing, magnetic particle inspection, and radiographic testing are used to verify the integrity of welds and connections.
- Load Testing (if required): In some cases, load testing might be performed to confirm the structural integrity of the revamped facility.
