• Proficiency in quantity take-off and BOQ preparation to client methods of measurement and industry norms (inch-dia, inch-metre, tonnage).
• First-principles rate build-up, productivity analysis and resource loading.
• Good knowledge of the Middle East market for pipe.
• Quantity extraction from 3D models (Navisworks, E3D / S3D review).
• Knowledge of piping materials (CS, SS, duplex, GRE) and welding / PWHT requirements.
• Awareness of civil and E&I interfaces with the mechanical scope.

Additional Information

• Competitive salary and benefits package offered.
• Depending on the nature of the position and its associated compliance risk level, a background check may be carried out.
