If you happen to check in on the live feed this week you will see a LOT of activity on the site. We have dug down for the lower level of the education/youth/office part of the building, and, of course, encountered rock there. But, we are making much faster progress on removing it since we have a wide open area to work in – faster than the rock in the trench for the piping going down to the stormwater pond that we have been working on for the past few weeks. We are also seeing dirt from the excavation being moved up the hill to form the base for the chapel and connector sections.
A lot of dirt and rock is being trucked out, too. One of the tasks of the site engineers during the design process is to quantify the amount of soil that will be removed from one area, and the amount of soil that will be needed in another area, and balance the two as much as possible. We don’t want to purchase soil and also truck soil away if there is any way to simply move it from one part of the site to another. Another factor is whether the soil that is being removed is suitable for the place where soil is needed – there are all kinds of characteristics that need to be taken into account. Sometimes we can’t tell until we dig into it whether soil will be suitable to be re-used on site or not, so there is a lot of knowledge and experience going into the decisions as each area is excavated.
