Some scientific/reconnaissance visits will tentatively be carried out to the following:

 

1.         Research Institute at KFUPM (XRD, SEM, and DTA).

 

2.         Laboratory demonstrations on assessment techniques and procedures.

 

3.         A fusion-bonded epoxy-coated rebar factory.

 

4.         A construction site where foundations are being protected against deterioration.

 

5.         A construction site where assessment of a structure is being conducted.

 

6.         A construction demonstrations on assessment techniques and procedures.

 

 

Each student has to make the necessary arrangement for one field trip.
