Engineer and Project Manager for a road development project?

Answer 1

2. The different stages of a complete Infrastructure development life cycle as follows:-

Wider Context - It is basically Stage I  When a builder starts to defining project options and evaluating options, it is necessary to identify the potential environmental impact and costs.

Project Startup - Stage 2, the summary of the project, requires a cost-benefit analysis to determine if the project is feasible if it will be profitable and what its environmental impact will be.
In Stage 3, the delivery strategy is established. The government may decide to build the project by itself, give contract it to one of its sub-units, or to the private sector organization. At this stage, it is also important to decide where the funding for the project comes from and where the ownership of assets and risks, including environmental risks, resides.

Project Delivery - Stage 4 of the model is the short design phase, during which technical solutions and plans are developed for the necessary contracts and acquisitions. Environmental requirements can be recognized to encourage pioneering design. After all this, the infrastructure is started to built (Stage 5) and the first physical environmental impressions are made. The quality of the construction determines the extent of future environmental performance.

Operational Service - After the completion of the construction of the infrastructure, the operation begins (Stage 6). This is the lengthiest phase of the process. This is also the place where the greatest environmental impact occurs in certain specific types of infrastructure. During this phase, it is essential to maintain the infrastructure to accomplish sustainability.
          
The last phase of the life cycle of an infrastructure project is the elimination/deactivation phase (Stage 7). The infrastructure generally lasts a relatively long time, but is not, however, eternal. Considerable long-term environmental damage can also occur at this stage.
