Dominion Street Improvements- Phase 1 (Retaining Walls)
Zone B
Soil retaining walls and micro piles are essential for stabilizing foundations. These structures provide
support and prevent soil erosion, ensuring the stability and longevity of the foundation.
Soil retaining walls are built to hold back soil and prevent it from collapsing or sliding. They are
commonly used in areas with steep slopes or where there is a significant height difference between
different sections of land. By creating a barrier, these walls redistribute the pressure exerted by the soil,
reducing the risk of foundation movement.
Micro piles, on the other hand, are small-diameter piles that are drilled into the ground to provide
additional support to foundations. They are typically made of steel or concrete and can be installed in
areas with limited access or low headroom. Micro piles transfer the load from the foundation to deeper,
more stable layers of soil, increasing its overall stability.
By incorporating both soil retaining walls and micro piles into foundation design, engineers can ensure
that structures remain stable even in challenging soil conditions. These techniques not only enhance
safety but also extend the lifespan of buildings and infrastructure projects.
The construction of a concrete retaining wall in a stepped manner involves building a series of horizontal
steps or terraces using concrete blocks or poured concrete. This method is used to create a stable and
visually appealing structure that can support soil and prevent erosion on sloped terrain. The steps are
typically designed to accommodate the natural slope of the land, providing a more gradual transition
between different levels. This type of retaining wall construction requires careful planning and precise
execution to ensure structural integrity and long-term stability.

Preservation of surrounding trees and rivers in construction projects
In today’s rapidly developing world, construction projects are essential for urban growth and
infrastructure development. However, it is equally important to ensure that these projects are carried
out with the utmost care and attention to the environment. One of the important aspects of this is the
preservation of trees and nearby rivers.
First, a thorough survey should be done before any construction project begins. This survey identifies the
location of trees and rivers within the project area. By accurately mapping these features, construction
plans can be adjusted accordingly to avoid unnecessary disturbance or damage.
Next, protective barriers should be installed around the trees to prevent any accidental damage during
construction. These barriers can include fencing or signs that clearly indicate that the area is off limits. In
addition, clear paths should be established to ensure that workers do not trample tree roots or disturb
their natural growth patterns.
Soil investigation and study for structural design is an essential process in engineering projects. It
involves conducting experiments and research to understand the properties and behavior of soil in order
to design safe and stable structures.
The first step in this process is site investigation, where soil samples are collected from different depths
using drilling or excavation techniques. These samples are then analyzed in a laboratory to determine
their physical and mechanical properties. Tests such as grain size analysis, moisture content, density,
shear strength, and consolidation are performed to assess the soil’s characteristics.
Additionally, field tests may be conducted to evaluate the in-situ properties of the soil. These tests
include standard penetration test (SPT), cone penetration test (CPT), and plate load test. They provide
information about the soil’s resistance to penetration, bearing capacity, and settlement characteristics.
The results obtained from these investigations help engineers understand how the soil will behave under
different loading conditions. This information is crucial for designing foundations, retaining walls,
embankments, tunnels, and other structures. It allows engineers to determine appropriate foundation
types, dimensions, reinforcement requirements, and construction techniques.
Furthermore, geotechnical reports are prepared based on the findings of the soil investigation. These
reports provide detailed information about the site conditions, soil properties, recommendations for
foundation design, and any potential risks or limitations that need to be considered during construction.
In conclusion, conducting a thorough soil investigation and study is vital for designing safe and reliable
structures. It provides engineers with valuable data about the behavior of soil under various conditions
and helps them make informed decisions during the design process.
