Item Comparative Study on Reinforced Concrete Pile Wall -And– Soldier Pile Wall with Timber Lagging (SHORING)(Addis Ababa University, 2017-06) Helen, Workineh; Ameyu, Temesgen (Mr.)In the recent year the construction of high rise buildings are significantly increasing in our country. Those buildings require large parking area, stores and other facilities that can only be fulfilled by constructing basements. For the construction of basements and underground passes have created need to go deep excavations into ground. Deep excavations are supported by shoring systems or pile walls. The project seeks to find out the better option between reinforced concrete pile wall and soldier pile wall with timber lagging in cost savings and feasibility of internal stabilized which have advantage like material availability, construction cost effectiveness, durability, easy construction and corrosion resistance and so on, for our country context. To achieve this objectives design reinforced concrete pile wall and soldier pile wall with timber lagging at different pile spacing (0.6m,0.9m ,1.2m,1.5m and 1.8m)and first anchor level (3.5m,3.7m,4.0m,4.5m and 5.0m) using deepXcav software, excel spread sheet and hand calculation done and based on the outputs form these analysis have been done cost estimation (bill of quantity) preparation for the purpose of cost comparison. Finally, the comparison of the two shoring system is carried out based on safe design and the cost efficient. The cost analysis and the optimum design disclose that the cost of solider pile higher than reinforced concrete pile wall.
