                                Pier Construction :           Pier is a substructure of viaduct that is supported by closely spaced piles and transfers all the loads from superstructure to ground through pile foundation.           Two types of piers are used in the project : 1.     Station pier (square)           Dimensions being 2400 mm x 2000mm. 2.     Eccentric pier (viaduct)           Diameter of eccentric pier is around 1.8m. Methodology : 1.     Vertical Reinforcement are aligned and supported with concrete blocks. 2.     Other reinforcements like rings and link rods are then tied according to design and bar bending schedule. 3.  ...

                                Pile Foundation:       Pile foundation is a type of deep foundation.      It is  done where shallow foundation is not possible because hard rock strata is not available at upper levels of ground.      Load is transferred to ground through skin friction and end bearing reaction.      In this project depth of piles is around 14m and diameter is 1m. But it can be as deep as 50m.      It is very slow and steady process and high accuracy is required. Methodology:       1.     After the geotechnical survey is done, Survey Coordinate and Control Points are marked. 2.     Boring is done with pile boring machine/rig machine until hard rock strata is found or as per plan. Depth is known by chain sounding method. 3.     If ...
