Life cycle of a project

Engineering Services during the whole product life cycle of your assets.

You can call upon PMC in every phase of your project, as we have expertise around the whole product life cycle in our team.

Typically, we distinguish the following phases:


Tender, design, procurement, construction, operations & maintenance, decommissioning

The terminology may vary in different sectors, but the concept remains the same.

These phases as a whole are often referred to as the product life cycle. When people talk about a project life cycle, they usually mean design, procurement and construction.


A tender is a procedure in which organisations make submissions to supply a certain service or product. This tender is normally awarded on the basis of several factors, usually price and/or quality.

What belongs to this phase:

  • Research and Development
  • Drawing up specifications


Design is the process of elaborating upon the specifications of an object so that it can be manufactured.

  • Concept Design
  • Basic Design
  • Detailed Design


Procurement is a whole process of acquiring or purchasing goods and services.

The related processes comprise the preparation and transformation of the requirements into processes, as well as receipt, acceptance and payment.
The following activities are part of the procurement process:

  • Purchase planning
  • Standardization
  • Developing specification
  • Investigating and selecting suppliers
  • Value analysis
  • Financing
  • Negotiations on price
  • Purchasing
  • Contract management and administration
  • Management of stock and storage facilities
  • Management of surplus and waste products


The life phase ‘Construction’ is related to building installations. Important elements of this phase are:

  • Construction management
  • Planning
  • Safety
  • Quality control
  • Inspection

Operations & maintenance

The life phases O&M concern the use and maintenance of constructions, machines and installations. Many engineering activities take place while installations are in use, e.g. re-engineering with a focus on production improvements and preventive maintenance. For certain installations, extensive maintenance or revision needs to happen on a regular basis. In these cases, the aim of engineering is always to disrupt the production process for as short a time as possible. Here we talk of

turnaround management and shutdown management.


Decommissioning is the disassembly or removal or an installation, focusing on safety and the environment, and intervening as little as possible in ongoing production processes.
