During the foundation and excavation phase of building a home, several crucial steps must be followed to ensure a strong and stable foundation.
1. SITE PREPARATION -
Prepare the construction site by clearing vegetation, debris, and obstacles, ensuring a level and stable base. In mountainous areas, address tree mitigation within required zones by cutting down trees or pruning the tree canopies. Conduct a survey to identify property boundaries, elevation changes, and potential obstacles. The contractor then marks the foundation layout using stakes and strings, aligning with architectural plans and building codes.
2. EXCAVATION -
The contractor will excavate the foundation trench to the specified dimensions and depth using heavy equipment like excavators or backhoes. After pouring the concrete foundation, they'll backfill the area around the foundation walls with compacted soil or gravel, ensuring stability. Finally, they'll grade the landscape away from the foundation to prevent water pooling near the structure.
3. CONCRETE -
Construct the foundation walls using concrete, masonry blocks, or poured concrete, ensuring proper reinforcement with steel rebar and alignment with the layout plan. Before pouring the basement slab or floor, install rough plumbing and electrical lines, including drainage pipes, water supply lines, and electrical conduit, to be concealed within the finished basement walls and floors. Finish any remaining preparations, such as installing termite barriers, insulation, or vapor barriers, before advancing to the next construction phase. Typically, a foundation, concrete, and/or excavation inspection occurs at this stage.
