Indian Oil Corporation Limited (IOCL), India's flagship Fortune 500 national oil company operating under the administrative oversight of the Ministry of Petroleum and Natural Gas, published an open competitive tender on the Government e-Marketplace (GeM) under Bid Number GEM/2026/B/7972865 (Tender Notice No: BN26ES117 / Item Reference: 9819726). This specialized engineering documentation tender solicits bids from competent technical drafting bureaus, CAD/GIS consultancies, and engineering design MSMEs for an "Annual Rate Contract (ARC) for Preparation, Digitization, and Updation of Various Engineering Drawings" at the Bongaigaon Refinery complex, situated in Chirang District, Assam (Pincode: 783385).

With the active bidding deadline concluding on 18 September 2026 at 03:00 PM IST, this procurement represents a prime, high-value technical gateway for specialized engineering drafting agencies, digital archiving startups, and CAD design MSMEs. Operating as a downstream petroleum refining and petrochemical manufacturing facility with a crude processing capacity of 2.35 MMTPA, Bongaigaon Refinery continuously executes plant debottlenecking, piping modifications, instrument retrofits, electrical substation upgrades, and civil infrastructure expansions. Maintaining 100% accurate, digitized "as-built" engineering drawings is a mandatory statutory requirement under the Petroleum and Natural Gas Regulatory Board (PNGRB) and Directorate General of Mines Safety (DGMS) safety codes. In accordance with Central Government Public Procurement Policy, eligible Micro and Small Enterprises (MSEs) holding valid Udyam Registration enjoy complete exemption from Earnest Money Deposit (EMD) requirements. This comprehensive TenderMan procurement intelligence dossier delivers an exhaustive breakdown of the technical drafting scope, layer management protocols, software standards, financial terms, and bid submission strategies.

QUICK TENDER OVERVIEW

In high-hazard chemical processing facilities like oil refineries, engineering drawings are living technical assets essential for plant integrity, process safety management (PSM), and emergency response. Bongaigaon Refinery operates multiple continuous catalytic reforming units, diesel hydrotreaters, crude distillation units, captive power plants, and vast tank farms. Decades of engineering modifications, field red-line markups, and legacy paper blue-prints must be systematically migrated into vector-accurate, standardized Computer-Aided Design (CAD) digital formats.

This Annual Rate Contract covers the drafting of new schematics, field verification of existing piping and instrumentation diagrams (P&IDs), conversion of raster scans to intelligent vector CAD files, electrical single-line diagram updates, and structural civil layout digitizations. For a specialized engineering drafting MSME or CAD consulting startup, securing an IOCL refinery rate contract establishes supreme technical credibility, provides consistent billable drafting hours throughout the year, and opens the door to downstream oil and gas engineering consultancies across India.

Indian Oil Corporation Limited is India's largest commercial enterprise, meeting over 47% of the nation's petroleum consumption needs through an extensive network of 11 refineries, 19,000+ kilometers of cross-country pipelines, and tens of thousands of retail outlets.

The Bongaigaon Refinery, located in Western Assam, was commissioned in 1979 and joined the IndianOil family in 2009. The Enginee
