5. Testing & Handover
Structural inspections and as-built documentation for commissioning.
Benefits of Our Steel Structure Fabrication & Erection Services
1. Integrated Engineering + Construction Execution
Most contractors require separate coordination between engineering consultants and fabricators. We provide in-house design, PE/QP submission, shop drawings, and direct execution — ensuring faster turnaround, fewer errors, and better control.
2. Specialized in Process Industry Requirements
Others may come from general building or warehouse structure backgrounds. We specialize in process plants, with structural designs that consider: Equipment loads and vibration, Pipe and cable tray integration, Explosion-proof compliance (Zone 1/2), Maintenance access and safety.
3. Modular & Preassembled Delivery
Typical fabricators deliver loose components requiring full assembly on site. We deliver modular or partially preassembled units, reducing: On-site hot works by up to 40%, Erection time and manpower, Safety risks during installation.
4. Proven Performance in Live & Flammable Plants
Many contractors avoid working in live plants or hazardous areas. We have completed multiple projects in operating chemical and coating plants, executing: Night-shift installations, Work in flammable environments, Strict permit-to-work and gas-free protocols with zero LTI (Loss Time Incident).
5. Total Package Delivery
Others may only do fabrication or installation. We cover: Foundation and civil works, Steel design, fabrication, and erection, Mechanical support frames, platforms, walkways, Final as-built documentation and compliance testing.
6. Fast Response & Flexible Execution
Big contractors often lack flexibility or take longer to mobilize. We offer: Quick response and quotation turnaround, Close coordination with your engineers, Adaptability to site constraints and changes.
Frequently Asked Questions
1. How long does it take to fabricate and erect the steel structure?
The timeline depends on the size and complexity of the structure. As a guide, a 50–80 ton steel structure typically takes 4–6 weeks for fabrication and 2–3 weeks for erection. We optimize schedules based on site conditions and coordination with other trades.
2. Can you work during live plant operations or shutdown periods?
Yes. We frequently operate in live plant environments, including during night shifts or planned shutdowns. Our team follows strict safety procedures to avoid disruption to production and maintain compliance with plant-specific protocols.
3. Is your steel structure suitable for installation in explosion-proof or hazardous zones (Zone 1/Zone 2)?
Yes. Our steel structures are engineered and installed to comply with hazardous area classifications, including Zone 1 and Zone 2. This includes: Proper earthing and bonding of all steel components to prevent static discharge, Coordination with Ex-rated equipment such as cable trays, light fittings, and supports, Strict control of hot works, including permits, gas checks, and fire watches, Use of pre-assembled modules to minimize on-site welding, Handover documentation including earthing continuity test reports and compliance records.
4. What codes and standards do you follow?
We typically follow BS5950, EN 1993 (Eurocode 3), and AWS D1.1 for structural design and welding. Client-specific or regional standards can be incorporated as required.
5. Do you provide shop drawings and PE/QP endorsements?
Yes. Our in-house engineering team produces detailed shop and fabrication drawings, and we can coordinate PE or QP endorsement and authority submission if required for local compliance (e.g., Singapore BCA/SCDF).
6. What finishing options do you provide for corrosion protection?
We offer various surface treatments, including: Hot-dip galvanizing for outdoor or coastal applications, Epoxy or PU paint systems for chemical or food environments, Stainless steel (SS304/SS316) for cleanroom or high-humidity areas.
7. Can your steel structure integrate with existing plant infrastructure?
Yes. We conduct on-site measurements or 3D scanning to ensure alignment with existing structures, equipment foundations, pipe racks, and platforms. Retrofitting is done with careful structural tie-in and load transfer consideration.
8. Do you handle foundation and civil works as part of the package?
Yes. We provide a full turnkey package that includes foundation design, piling, anchor bolt setting, grouting, and structural base preparation, ensuring smooth coordination between civil and steel erection scopes.
9. What QA/QC measures do you follow during fabrication and erection?
Our QA/QC process includes: Material traceability and certification, Welding inspection (visual, UT/MPI if required), Bolt torque and tension checks, Dimensional and verticality checks, Final inspection and sign-off with the client.
10. Do you provide as-built drawings and final documentation?
Yes. Upon completion, we provide: As-built drawings (PDF + editable format), Load test or pull-out reports (if applicable), QA/QC records, inspection checklists, and test reports, Full documentation package for client records and authority submission.
