Understanding Basic Engineering vs Detailed Engineering is essential for any industrial project. These engineering phases in projects shape the project from initial concepts to final execution, ensuring smooth progression, cost management, and technical feasibility.
What is Basic Engineering?
Basic Engineering is an essential phase in the life cycle of industrial projects, as it connects concept planning with detailed design. In recent years, traditional engineering tools have been integrated into analysis tools. It converts the initial ideas into detailed plans that meet both technical and economic necessities. The outcome is a blueprint design for a fusion reactor’s principal components, including reactors, pumps, piping systems, control technologies, and waste management, which will guide the ensuing steps in the engineering process.
Engineers shape the overall design, confirming technical and economic requirements. They help provide specifications for key equipment, piping, and control systems, serve as a roadmap for the detailed engineering phase, and ensure seamless passage through to subsequent stages.
What is Detailed Engineering?
Detailed Engineering is the phase of a project that shifts from conceptual and basic designs to a comprehensive set of plans for construction and implementation. It consists of perfecting the original designs and defining the materials, dimensions, requirements, and technical specifications for every aspect of the project.
In this phase, engineering teams develop detailed drawings, layouts, and specifications for equipment, systems, and structures. The construction and procurement plan and these documents are the foundation by which the elements involved are designed, regulated, and ready for actualization. Detailed Engineering confirms the ability to build projects efficiently, safely & within budgets.
Key Differences Between Basic and Detailed Engineering
Basic Engineering
Basic Engineering is all about delivering preliminary designs and checking the economic and technical feasibility. This includes conceptual planning, field studies, and cost estimation. The engineer determines the scope of the project, establishing design criteria, flow diagrams, and initial specifications of materials, equipment, and process stages. These run on unverified data and typically need client endorsement.
Documentation in Basic Engineering:
- Design bases and criteria
- Flow diagrams for processes
- Preliminary P&IDs and plot plans
- Equipment and material specifications
- Cost estimates (+/- 15%)
- Preliminary schedules and man-hour estimates
Detailed Engineering
Detailed Engineering is a level of design that defines and refines the basic design, concluding with execution plans for construction in sufficient detail to allow for procurement. This stage includes client-approved documents like PFDs, P&IDs, and equipment specs. It includes elaborate layouts, vendor details, and 3D models that are crucial for executing the project accurately. These engineering documents are the detailed inputs used through the building and procurement process and ultimately help achieve final sign-off from the client.
Documentation in Detailed Engineering:
- Client-approved PFDs and P&IDs
- Finalized plot plans based on actual equipment sizes
- Detailed structural, mechanical, electrical, and civil plans
- Specifications for materials, equipment, and systems
- Real vendor data for pumps, exchangers, vessels, and piping
- Detailed control system specifications and layouts
Differences in –
Documentation and Design Approach
Basic Engineering designs are conceptual in nature and built on high-level assumptions. Key deliverables during Basic Engineering include system and component failure rates, reliability studies, and preliminary design drawings in ITP format. The flow diagrams, equipment sizing, and other materials have all been prepared as estimates, pending approval from the client. In Detailed Engineering, actual data is used to finalize designs, including specifications for real equipment and construction-ready documents.
Project Scope and Planning
Basic engineering determines the functional requirements for the project, flow diagrams, and first cost estimates. From these, detailed engineering refines them to ensure that all of the designs meet all of the project and client specifications. In contrast, Detailed Engineering generates a clandestine and precise cost estimate, although Basic Engineering provides a rough cost (+/-15%).
Construction and Vendor Information
Basic Engineering is dedicated to estimating equipment and material quantities, including preliminary equipment size and vendor information.
Detailed engineering goes a step further, obtaining vendor information, such as pump specs, vessel sizes, real piping layouts, etc. This ensures everything is available and ready to start building.
Risk and Cost Management
Both steps involve risks and expenses, which are vital in managing the project. Basic Engineering provides an early estimate of costs, while Detailed Engineering provides a more accurate one. An effective Detailed Engineering stage minimizes delays and guarantees that there will be no deviations from the initial cost and period.
Production Engineering
Production Engineering is the next step once the design is finalized and approved by the client. This involves generating the rest of the drawings and documentation required for plant erection based on the completed 3D model or different design techniques.
Role of FEED engineering
Front-End Engineering Design (FEED) bridges the gap between Basic Engineering and Detailed Engineering. It refines concepts from Basic Engineering, providing more detailed designs, specifications, and cost estimates, but not to the level of detail required in Detailed Engineering.
FEED engineering ensures the project’s technical and economic feasibility before moving into the final construction phase. It typically involves defining the project scope and equipment specifications and finalizing designs for long-lead items. While Basic Engineering focuses on the overall project concept, FEED solidifies it further, setting the stage for Detailed Engineering, where actual construction plans are developed.

When to Use Basic Engineering?
Basic Engineering is meant to be utilized in the initial stages of a project, in which the conceptual designs must be elaborated to be more practical, actionable plans. This is also important in assessing a project’s technical and financial viability. Ideal for defining project scope, preliminary specifications, and cost estimates in this phase. It provides a basis for ascertaining the appropriate solutions to a project before entering a detailed design.
Basic Engineering is also a stable foundation for preparing the procurement, construction, and client approvals. It should be used when preliminary feasibility studies are needed to inform the direction of subsequent project work.
When to Transition to Detailed Engineering?
Move on to Detailed Engineering only after Basic Engineering has laid a strong groundwork and after the client has approved the initial designs. This phase follows the validation of the project concept upon verifying its technical and economic feasibility and the validation of all concepts. When project scope, preliminary specifications, and cost estimates have been established, it is time to move forward.
When you require exact designs for procurement and construction, Detailed Engineering is unavoidable. Detailed reports, equipment specifications, and drawings are delivered at this stage. It is crucial before proceeding with construction or buying materials because it ensures that all technical, safety, and operational requirements are within scope.
