Generation Construction Inspector

Principle Services is supporting a major utility client in the brownfield installation, start‑up, and commissioning of ten (10) Siemens SGT 800 simple‑cycle gas turbines and associated balance‑of‑plant (BOP) systems. We are seeking an experienced Generation Construction Inspector to provide field oversight, ensure contractor adherence to design and standards, evaluate construction progress, and support successful commissioning of the generating units.

This role extends beyond traditional inspection. The Generation Construction Inspector is expected to evaluate construction activities through a commissioning and operational readiness lens — proactively identifying installation conditions that could pass drawing compliance yet create performance, integration, or reliability challenges during energization and startup.

• Provide continuous field inspection of mechanical, electrical, civil, and structural work associated with Siemens SGT 800 turbine installation.
• Monitor site activities to ensure compliance with IFC drawings, project specifications, permit requirements, applicable industry codes/standards, and safety standards.
• Ability to evaluate work from an Owner’s Representative perspective, prioritizing long-term asset performance, reliability, and schedule protection.
• Inspect civil works such as turbine foundations, access roads, crane pads, structural supports, and site grading for quality and dimensional accuracy.
• Monitor mechanical installations including gas turbine alignment, bolting, welding, piping (fuel gas, lube oil, ammonia), and rotating equipment setup.
• Review electrical installations including medium/high-voltage cabling, transformers, switch gear, control systems, and grounding to ensure proper installation and safety.
• Witness and document key activities such as material receiving, concrete pours, welding, non-destructive testing (NDT), hydrostatic/pneumatic testing, equipment alignment, and pre-commissioning checks.
• Identify and report non-conformances, defects, or deviations; work with contractors and site teams to resolve issues promptly.
• Leverage prior testing and commissioning experience to identify installation deficiencies that could result in functional test failures, rework, or startup delays.
• Evaluate construction activities with consideration for commissioning sequence, energization strategy, and operational reliability.
• Identify latent defects, system interface conflicts, and incomplete installations prior to formal turnover or walkdowns.
• Proactively communicate emerging risks that may impact mechanical completion, first fire, synchronization, or performance testing milestones.
• Coordinate with Siemens representatives, EPC contractors, subcontractors, and third-party inspectors during critical installations and testing phases.
• Mentor junior inspectors on common construction issues and expectations of gas generation projects.

• Maintain daily inspection logs, progress photographs, and quality observations.
• Review contractor work packages, ITPs, test reports, and redlines for alignment with commissioning requirements and turnover sequencing.
• Track, document and escalate non‑conformance reports (NCRs), punch‑list items, and corrective actions that may delay system acceptance.
• Provide weekly summaries to the Owner’s Representative team and participate in progress meetings.
• Support turnover package compilation, including as-built documentation and QA/QC records for handover to operations.
• Partner with Siemens and contractor’s commissioning teams to evaluate construction readiness prior to energization and startup.
• Identify installation practices that may impact turbine performance, protection schemes, emissions compliance, or long-term reliability.
• Support structured system walkdowns, A/B/C punch categorization, and turnover sequencing, and milestone validation (mechanical completion, first fire, synchronization, performance testing).
• Ensure construction quality aligns with commissioning and operational performance objectives — not solely drawing compliance.
• Observe functional testing, walk‑downs, loop checks,…
