Environmental assessments (EAs) are an important component of any civil engineering project. Delgado Engineering has been contracted to design and assess a multibillion-dollar urban rail center in a city, which is divided in the middle by a river. The center will be built on a previously unused island in the center of the river. For each of the four types of civil engineers (construction engineer, geotechnical engineer, structural engineer, transportation engineer), explain why they should be involved in the project—or why they would not be relevant to the project—and what their role would be. Then describe how the EA would proceed, including what might be included in the environmental impact assessment process, such as the use of geographic information systems. Finally, explain what might be in the environmental impact statement or why you think there may be a finding of no significant impact.

1) Geotechnical Engineers; These engineers are responsible for testing the capacity of the soil to safely carry the building load. In cases where the soil is too weak or doesn't meet the engineering requirement for the project, these engineers could carry out soil improvement techniques or even recommend a deep foundation.

2) Structural Engineer; The structural engineer is responsible for ensuring that the structure is safe for it's intended use and that structural members of the structure are designed in such a way that all the load of the structure is safely transmitted to the ground without uneven settlement.

3) Construction Engineer; The construction engineer is the one that is responsible for implementing the working drawings of the urban center through thorough daily supervision of all the construction works.

4) Transport Engineer; The transport engineer is very important because he is the one to carry out traffic studies and come up with a transport design solution that is effective in gaining safe and smooth access to the proposed new urban rail center.

When we talk of Environmental Impact Assessment in Construction works, we are referring to the impact of the construction work on the immediate environment.

Now, in an unused island they will definitely make use of shallow foundations and also make use of a lot of sand which will require lots of dredging from water.

Thus, the EIA will need to be done to know the impact of the vibrations from the drilling of piles and also the effect of the excess dredging that will be required to fulfill the capacity of the sand needed for the construction.
