Detailed Engineering Services

Assinov’s Detailed Engineering Services convert project intent into buildable, compliant, and cost‑effective designs. We produce coordinated, discipline‑wise deliverables that de‑risk construction, accelerate procurement, and keep site execution predictable.

From design basis and specifications to construction drawings and handover packs, our teams integrate process, piping, mechanical, civil/structural, electrical, and instrumentation into a single, clash‑free engineering model aligned to your codes and standards.

Scope: Multi‑discipline detailed design and documentation from approved FEED/P&IDs, vendor data, and site inputs.
Deliverables: Specifications & data sheets, calculations, 3D/2D drawings (GA/layouts/isometrics), MTO/BOM, cable & I/O schedules, fabrication/shop drawings, and as‑built packages.

Service Offerings

• Process & Piping: line lists, valve lists, tie‑in lists, PFD/P&ID updates, pipe routing, stress analysis (CAESAR II), supports & specialties, isometrics with MTO
• Mechanical: equipment data sheets, specifications, vendor data review, nozzle orientation, GA drawings, skid/baseframe design, fabrication drawings
• Civil & Structural: foundations, pipe racks, platforms & walkways, stairways/ladders, equipment buildings/shelters, connection details, rebar & formwork drawings
• Electrical: single‑line diagrams, load lists, cable sizing & routing, grounding/lightning protection, substation layouts, lighting layouts, BOQs
• Instrumentation & Control: instrument index, I/O lists, hook‑up drawings, loop diagrams, cable tray layouts, JB layouts, control room layouts
• Layout & 3D Model: AVEVA/Plant 3D model, equipment layout, piping layouts, clash detection & resolution, model reviews, 2D extractions
• Procurement Support: MR/SOW, TBE, vendor drawing review & compliance checks, inspection/QC plan inputs
• Construction & Handover: IFC packages, installation details, test packs, red‑line capture, as‑built dossiers and O&M documentation
