Detailed Engineering builds upon the foundation established in Basic Engineering/FEED, providing the most comprehensive and detailed engineering deliverables necessary for construction and project execution. The services encompassed within Detailed Engineering typically include:
Detailed Engineering Drawings: Engineers prepare detailed engineering drawings for all disciplines, including piping and instrumentation diagrams (P&IDs), mechanical equipment drawings, civil and structural drawings, electrical schematics, and instrumentation diagrams.
Piping Design and Stress Analysis: Detailed piping layouts are developed, considering routing, supports, and stress analysis to ensure safe and efficient operation.
Mechanical Equipment Design: Detailed mechanical equipment designs are prepared, including fabrication drawings, material specifications, and installation procedures.
Civil and Structural Design: Comprehensive civil and structural designs are developed for foundations, buildings, and other structures, ensuring structural integrity and compliance with building codes.
Electrical Design and Power Systems: Detailed electrical designs are prepared for power distribution, lighting, grounding, and control systems, ensuring reliable and safe operation.
Instrumentation and Control Systems Design: Detailed instrumentation and control system designs are developed, including wiring diagrams, control logic, and software programming.
Procurement and Vendor Management: Engineers manage the procurement process for all equipment, materials, and services, including vendor selection, bid evaluation, purchase orders, and expediting deliveries.
Construction Support and Coordination: Engineers provide technical support during construction, including site visits, clarifications, design changes, and coordination with contractors to ensure proper implementation of the design.
Quality Assurance and Quality Control: Engineers implement quality assurance and quality control procedures throughout the detailed engineering phase, ensuring that all deliverables meet project specifications and industry standards.
Construction Drawings and Specifications: Detailed construction drawings and specifications are prepared for all disciplines, providing clear instructions for contractors and ensuring accurate construction according to the design.
Bill of Quantities (BOQ) Preparation: A comprehensive bill of quantities (BOQ) is prepared, detailing the quantities of materials, equipment, and labor required for construction, enabling accurate cost estimation and project budgeting.
Construction Procedure Specifications: Detailed construction procedure specifications are developed, outlining the specific methods, techniques, and sequences for various construction activities, ensuring safe and efficient execution.
Construction Schedule Refinement: The project schedule is refined based on detailed engineering deliverables and construction requirements, providing a more accurate timeline for project completion.
Construction Cost Estimating: Detailed construction cost estimates are prepared based on the BOQ, construction drawings, and specifications, providing a more precise project budget and identifying potential cost-saving opportunities.
As-Built Drawings and Documentation: As-built drawings and documentation are prepared to reflect any changes or modifications made during construction, ensuring an accurate record of the final project configuration.
