Detailed engineering design and tender preparation for the 40 m Mitomoni Bridge and its 8.2 km bitumen-standard approach roads crossing the Ruvuma River in Tanzania.
Scope
The project covers the detailed engineering design and tender document preparation for the Mitomoni Bridge (three spans totaling 40 m) and its 8.2 km bitumen-standard approach roads crossing the Ruvuma River, linking the Songea and Nyasa Districts in southern Tanzania.
Approach
Hydrological Analysis
Calculated discharge volume to determine correct structural sizing and bridge height.
Alignment Selection
Reviewed satellite imagery, topographic maps, and aerial photographs to identify the optimal crossing location.
Structural Modeling
Undertook detailed structural design in MIDAS Civil software, complying with TANROADS design specifications.
Outcome
Technical Packages
Prepared complete engineering drawings, technical specifications, Bills of Quantities (BOQ), and engineering cost estimates.
Bidding Documents
Prepared the full set of draft bidding documents in accordance with TANROADS standard bidding guidelines.
