D. Tendering and Technical Documentation

- Study tender documents, specifications, drawings, P&IDs;, single-line diagrams (SLDs), and BOQs.
- Prepare technical compliance statements, deviation statements, equipment schedules, and tender submissions.
- Identify missing items, technical discrepancies, and scope gaps in tender documents.
- Prepare technical clarifications and support pre-bid meetings.
- Ensure all estimated items comply with tender specifications and applicable standards.

E. Commercial Estimation and Vendor Coordination

- Obtain quotations from OEMs, panel manufacturers, instrument suppliers, cable suppliers, and automation vendors.
- Prepare comparative statements covering price, specifications, delivery, warranty, payment terms, and taxes.
- Negotiate with vendors to obtain competitive prices and suitable commercial terms.
- Calculate freight, insurance, installation charges, overheads, contingencies, and profit margins.




- Prepare customer quotations, techno-commercial offers, and final bid price summaries.
- Coordinate with procurement, engineering, finance, and project execution teams.

F. Project Budget and Handover

- Prepare the final project cost sheet after order receipt.
- Hand over approved BOQs, estimates, technical specifications, and vendor quotations to the execution team.
- Support project budget monitoring, variation costing, extra-item estimates, and change orders.
- Maintain an organized database of vendor quotations, equipment rates, and estimation records.
