Front-End Engineering & Design (FEED) Capabilities

Clients rely on Alir Constructions to adequately define their project requirements before initiating a capital investment. Alir Constructions's front-end engineering and design (FEED) teams, with experience gained providing FEED services to clients in diverse industries, prepare documentation to support clients' future investments.

Alir Constructions has provided FEED services for thousands of major projects, including first-of-a-kind technologies, world-scale mega projects and licensor design packages. We have extensive experience preparing lump sum bid packages, as well as reference packages to facilitate completion of work in an expeditious timeframe.


Front-end engineering and design is the work required to produce quality process and engineering documentation of sufficient depth, defining the project requirements for detailed engineering, procurement, fabrication and construction of facilities and supporting a ±10 percent project cost estimate. This distinct project phase is typically used to:

  • Conduct hazardous operations reviews
  • Develop the engineering design packages that can be used to bid a lump sum EPC scope and / or provide the foundation for the detailed engineering phase
  • Evaluate options that will improve the return on assets (ROA)
  • Prepare cost estimates for scope definition and for project funding
  • Support internal funding requirements

We know that every decision has an impact.

As industry leaders, we model the highest standards of corporate social responsibility with uncompromising commitment to diversity, inclusion, sustainability and innovation. We do this in collaboration with our clients, partners and communities to build a better future, together.
