Hello, I am a Mechanical Engineer with over 16 years of hands-on experience in Oil & Gas EPC, process skid manufacturing, and heavy structural fabrication. My background directly aligns with your requirements for reviewing technical specifications, P&IDs, GADs, and preparing precise material take-offs (MTO/BOM). Throughout my career (including 10 years at 3C Metal Middle East), I have spearheaded mechanical estimation, cost optimization, and vendor quote evaluations for complex modular process packages, piping, and structural skid systems. Here is how I will support your proposal activities: - Thorough P&ID, GA Drawing, and RFQ Review to define exact execution scope. - Preparation of Detailed MTOs & BOMs for structural steel, piping, valves, and mechanical equipment. - Labor & Fabrication Costing (welding, machining, assembly, testing, and painting). - Cost Optimization & Value Engineering to ensure competitive bidding. Assumptions & Exclusions: 1. CAD/2D/3D Drafting excluded (estimates based on provided GADs/P&IDs). 2. Client to provide Approved Vendor List (AVL) for pricing reference. 3. Estimation relies on Client-provided shop norms (man-hour rates, welder efficiency factors, and capacity limits). 4. Timeline/turnaround excludes external vendor quotation response delays and non-working days (weekends). I am well-versed in ASME, API, and ISO codes, proficient in Excel modeling, and ready to start immediately. Arjun Chavan
