Excavator Digs Walk-Out Basement for New House

Basement Excavation and Site Preparation

• excavator is used to dig a walk-out basement for a new house on a lake lot.
• The house was repositioned 25 ft uphill to accommodate the walk-out design, increasing the basement depth to approximately 5.5 ft.
• The process involves stripping and stockpiling topsoil separately for later use in backfilling.

Excavation Process and Equipment

• A 220 excavator is utilized for the primary digging, chosen over a mini excavator due to the significant amount of dirt to be moved.
• The excavator is equipped with 2D grade control to assist in achieving the correct elevation and a straighter dig.
• Dirt is hauled away using an on-road dump truck, with the majority stockpiled in the front of the property due to limited working space.

Challenges and Material Handling

• The excavation encounters significant roots from previous tree clearing and a layer of clay rock, making digging more challenging.
• The topsoil is noted to be surprisingly abundant and of good quality for backfilling.
• The dump truck is essential for hauling away the large volume of excavated material, with an estimated 50 loads already removed.

Site Management and Future Steps

• A large mountain of dirt is created on-site due to the volume of excavation.
• A portion of the site is designated as a septic field, requiring careful management of dirt stockpiles.
• The plan for the next day includes finishing the excavation, cutting a perimeter footing for concrete walls, and hauling 200 tons of stone.
• The excavated dirt will eventually be spread to backfill the foundation, creating a more natural grade around the house.
