The estimated duration of construction is approximately 3 years. The construction of thefoundations takes about 28 months. The steel trusses are fabricated and assembled off-site andtherefore many activities can run in parallel, benefitting the construction program. The erection of thesteel trusses and subsequent placement of the precast top slab panels will be a relatively fast process,particularly if the contractor opts to use a large heavy duty floating crane. The schedule ofimplementation is presented in Figure 2-13. The tentative construction schedule for RTW (Figure 2-14)shows that the work can be built in parallel to the main bridge. It is important to note that two mainworking seasons (dry seasons) are required after one first dry season for stockpiling and mobilization.2-22
