Engineering Design

Easton Industrial Air can also offer engineering design working with clients in determining design requirements and problem definition for all their Mechanical HVAC needs. Design requirements assist in design of the process being developed and can include feasibility studies.


  • Feasibility Studies – Purpose of a feasibility assessment is to have an evaluation of the potential of the proposed project and aid in decision-making. The project is assessed and based on an achievable idea that can be executed within cost constraints and proceed into the design phase.
  • Conceptualization – This is the early phase of the design process in which the bigger picture of design is formed and articulated. This often leads into the next phase the FEED.
  • Preliminary Design – This phase is also known as Front End Engineering Design and is the basic engineering, which comes after the conceptual phase. The FEED phase focuses on technical requirements as well as rough investment cost for the project.
    • FEED Deliverables include:
      • Updated Design Base Memorandum
      • Project Schedules Level 1
      • Cost Estimates (+/- 25%)
      • Project Execution Strategy
      • Permitting & Regulatory Compliance Plan
      • PFD & PUD preliminary drawings
      • Preliminary Sizing equipment & Specifications
    • Detailed Engineering Design – Following FEED is the detailed engineering phase and in this phase design is refined and include 2D & 3D models, P&IDs, cost estimates, procurement plans. A spreadsheet below identifies full detailed deliverables per discipline & FEED.
