1. An excavation is to be made for a footing 1.5 m x 1.5 m. However during the excavation you encountered the water table as shown the depth of excavation to be is 2m from the surface but the ground water table is 1m from the surface. How will you be able to pour the concrete mix for the footing if ground water is continuously infiltrating into your excavation and filling up the pit with water. Draw each stage of the excavation up to finishing up the footing with a short explanation for each drawing, include stage of placing formworks and rebar as well as other process to ensure that additional ground water will not mix with your newly poured concrete. Imagine you are already an engineer trying to illustrate to your client or your workers how will you make the footing (the photo shown is just 1m excavation you still have 1m more to excavate) Ground water table level

Question
Transcribed Image Text:1. An excavation is to be made for a footing 1.5 m x 1.5 m. However during the excavation you
encountered the water table as shown the depth of excavation to be is 2m from the surface but
the ground water table is 1m from the surface.
How will you be able to pour the concrete mix for the footing if ground water is
continuously infiltrating into your excavation and filling up the pit with water. Draw each
stage of the excavation up to finishing up the footing with a short explanation for each
drawing, include stage of placing formworks and rebar as well as other process to ensure
that additional ground water will not mix with your newly poured concrete. Imagine you are
already an engineer trying to illustrate to your client or your workers how will you make the
footing (the photo shown is just 1m excavation you still have 1m more to excavate)
