KEY ROLES Monitor and verify all construction activities (e.g civil, structural, electrical) against approved drawings, specifications and conduct physical measurement of work done against progress report. Ensure all construction works meets CLIENT ’s engineering practices and applicable international codes. Work closely with construction supervisors and planners to validate quantities. Evaluate and price site-driven changes such as unforeseen ground conditions, scope changes or safety related adjustments. Ensure robust documentation of site instructions, early warnings and change orders. Work closely with HSE teams to integrate safety- especially in critical civil structural operations like excavation, formworks piling, lifting. Participate in TBT and site walkdowns if needed to understand scope impact. Support weekly and monthly cost and progress reports to the site leadership team. Collaborate with planners and schedulers to integrate earned value data. Provide input into value-of-work done (VOWD) reporting to project control team. Indentify, quantify and document claims from contractors or suppliers. Support defense or negotiation of claims through proper records and contract interpretation. Track labor and equipment productivity, Identify where low productivity is causing cost overruns or schedule delays and flag any areas of concerns raise to Construction Lead. Develop productivity improvement support by suggesting work sequencing adjustments, workforce allocation or subcontract strategy based on productivity finding BASIC SKILLS Strong numerical and analytical skills for accurate measurement and cost analysis. Understanding of construction methods and sequencing (Civil, structural, mechanical and E&I). Strong understanding of civil structural engineering principles related to construction. Familiarity with CLIENT  engineering standards and industrial codes like ACI, ASTM, BS, ISO and ASME. Ability to interpret technical drawings, specifications and contracts. Proficient in cost estimation, budget tracking and forecasting. Skilled in record-keeping, including site diaries, variations logs. Ability to prepare interim valuations, final accounts and change order documentation. Clear and professional verbal and written communication. Ability to coordinate with site teams, contractors and internal departments. Ability to identify cost or productivity issues early and recommend corrective actions. TECHNICAL QUALIFICATIONS Minimum bachelor’s Degree in Civil Engineering or related discipline (e.g Structural engineering, construction engineering)Desired – previous experience on quantity surveying and proven track record delivering required role or similar within the Oil & Gas Industry. EXPERIENCE Minimumum 5-10 years of quantity surveying experience in construction, preferably in oil &gas petrochemicals, or energy sectors). Site-based experience managing construction works (civil, structural, mechanical, E&I, piping on Brownfield or greenfield projects. Familiarity with project specifications and drawings review. Experience with cost tracking, remeasurement, change control and final account preparation RESPONSIBILITIES & OBJECTIVES Track and manage construction cost against the approved budget. Conduct on-site quantity measurement and verify work done (VOWD). Manage site instructions, change orders and variation orders. Monitor labor and equipment productivity against baseline benchmark. Analyse cost per unit outputs and flag inefficiencies to project control. Support early warning notices and maintain commercial risk registers. Identify and quantify scope changes cost/time impact and maintain change logs. Objective: Deliver accurate and timely commercial management of site construction activities. Ensure all site works are measured, valued and paid for in accordance with contract terms. Proactively identify and manage commercial risk and opportunities raised at execution of site works. Maintain excellent communication and collaboration with site stakeholders
