Detailed investigation and a full assessment of the conditions of a number of structures. These structures include bridges and underpasses that are located along different parts of the Qatar road network and they vary in age, type, size and condition. The following is a list of these structures and their locations:
(i) Northern Relief Road Bridge 1;
(ii) Northern Relief Road Bridge 2;

Phase 1:
a) detailed inspection and full structural assessment of the structures;
b) preparation of a report documenting the assessment and identifying the required repairs;
Phase 2:
a) Preparation of engineering drawings and tender documents and cost estimates for the required repair works separately for each structure.
Phase 3:
a) Site supervision and construction management of the repair works.
