Earth movement
Storyboard
Today, January 25, 2023, we have started the earthmoving work. The work will be carried out by Andrés Naguil, who is locally considered one of the most experienced.
We began by creating the access and will then proceed to fill in so that the access is not too steep. Finally, we will continue to develop the large platform where the house will be built.

View at start
Description
This is the view of the plot from the road on the day of the intervention. In other words, the field is still in its natural state, and during the day, it will begin to transform into the platform where the house will be built (which can hardly be seen from this point) and the area from which earth will be extracted to create the entrance.

Developing the access road
Description
The first step takes place on the outer part of the parcel. We begin the process of reclaiming the old road, which, at this point, descended into a depression that was likely filled in due to the construction of the current highway.
Since part of the road already existed, the initial task involves clearing away the vegetation (blackberries) and slightly widening the path that had been covered by earth movements, probably associated with the filling of a higher area within the fiscal strip.
When working in areas like the fiscal strip, it's important to be aware of potential buried infrastructure. In this case, the machine operator had been involved in the water supply project and was familiar with the pipeline layout to prevent any damage.

Developing access
Description
At this point, several considerations must be taken into account to operate without causing damage. On one hand, the drainage network of the hill's water collector and the road are in close proximity to the work area, and any damage or modifications to these elements could compromise drainage in higher areas. On the other hand, the stacking of soil and its movement can potentially harm the roots and trunk of the tree located in the area. Therefore, the work was carried out in small stages, with careful observation of the elements (the drainage system and the tree) from the outside to ensure that no damage was caused.
In summary, special care should be taken with the following aspects:
Any modification to existing drainage systems could affect unrelated systems in higher areas.
Caution is required when dealing with vegetation intended for preservation, both due to the piling of soil in its vicinity (as the weight of the soil can damage the plants) and the weight of the operated equipment, which could potentially harm the roots.
Once the main descent was completed, it was necessary to lower the equipment to begin stacking soil and creating the embankment. The operator used the excavator's bucket to lower the equipment, facilitating its entry without issues.

Developing the inner path
Description
Once inside the parcel, the access road is developed to complete the entry curve. This involves excavating earth from the designated adjacent area for this process.

Obtaining earth from the hillside
Description
With the access road in place, the construction of the access ramp begins. To achieve this, the earth extraction zone is further developed. This area is also planned as a parking space, material storage area, and potentially even for the construction of a guest house.
At this stage, it's crucial to:
Have a clear understanding of the required volume of earth for the development of the necessary structures and its source.

Continuing the inner path
Description
Once the basic earthwork for shaping the entrance and the start of the ramp is completed, earth is further moved from the extraction area to the ramp area, following the baseline defined between the two key trees marking the edge and orientation.
This phase involves one of the most complex tasks, which is to create a ramp with a constant slope that ends at the level of the esplanade. Therefore, it is crucial to highlight the elevation of the esplanade's centerline and the upper limit marked by the line between the neighbor's cellar and the southeast corner of the parcel.
It's essential to take care to ensure that:
The ramp is constructed with a constant slope that must reach the elevation of the esplanade's centerline when it reaches its edge.

Arriving at the esplanade
Description
The arrival at the esplanade area is marked by crossing the imaginary line between the neighbor's cellar and the southeast corner of the parcel. At this point, the ramp filling must come to an end, as there should be a seamless transition between the ramp and the esplanade.

Beginning to develop the esplanade
Description
Upon reaching the level of the esplanade, it is crucial to emphasize the southern edge, where the wall will be located. This wall must be constructed with precision, as it is difficult to reconstruct once completed.
Therefore:
Special care must be taken when excavating the earth to form the esplanade wall, as it cannot be easily reconstructed, unlike the northern edge, which is formed through stacking and can be adjusted.

Deepening the esplanade
Description
Continuing along the central line of the esplanade to establish a reference for the level, it is important to note that not only is a footprint created at this level, but the soil is also mixed to create a layer of sufficient depth that can be compacted properly.
Therefore:
The soil is lifted and mixed to create a layer with the required elevation, which can be compacted and will maintain the original elevation.

Widening the esplanade
Description
In the process of widening the esplanade, material is gradually removed along the imaginary line at the southern edge (between the neighbor's cellar and the southeast corner of the parcel) and the northern edge, bounded by the line between the rock and the neighbor's cabin.
In this case, there is an additional danger related to loose material that could encroach upon the wetland area. Therefore, it is essential to:
Exercise caution with the material that may roll into areas where material is being piled, as it could invade areas where topography modification is not desired.

Removing rocks
Description
One of the challenges in the compaction process was dealing with large stones, with a diameter of more than 60 cm. Therefore, these stones were removed as they were encountered in the displaced soil.
In this case, it is important to:
Remove large rocks that may affect the compaction of the esplanade or the ramp.
Overall, the movement was nearly perfect, except that one of the rocks rolled and ended up in the middle of the wetland area, which was not the intended outcome.

General view
Description
After 10 hours of work, the shape of the access, ramp, esplanade, and the transformation of the earth extraction zone into a small upper esplanade can be largely observed.
Following this, 5 hours were spent refining the contours and compacting the entire area using heavy machinery.
