Construction Site Excavation Safety Steps

Excavation and trenching are naturally hazardous construction operations, and contractors need to take all the appropriate steps to ensure worker safety. The Occupational Safety and Health Administration (OSHA) defines an excavation as “any man-made cut, cavity, trench, or depression in the earth’s surface formed by earth removal.” A trench, in particular, is defined as “a narrow underground excavation that is deeper than it is wide, and is no wider than 15 feet (4.5 meters).”

When we approach any excavation, drilling or demolition job we keep safety first, starting with the planning for the job. It is not just the possibility of the sides of an excavated plot or trench collapsing. Safety planning also must accommodate the interaction of our people and the machines they need to employ to carry out the job, and the terrain on which those machines must operate.

Piles and Footers: Types of Foundations

Foundations vary in structure relative to the depth to which the foundation must be established in the ground. Small structures might only require a shallow foundation, which involves excavating between three and eight feet into the ground, before pouring a concrete footing.

Helical Anchor Installation Relies Upon Accurate Torque Measurements

Helical anchors enjoy widespread use today to help stabilize and secure above-ground structures, especially when that structure is built on ground that may be or has become unstable. The anchors themselves are steel shafts with helical coils or plates welded on at an angle. The shafts are screwed into the soil beneath the foundation to a depth that enables the coil to support the load. When foundation drilling calls for helical anchors, the depth of the anchor is drilled into the ground is determined by precisely measuring the torque it takes to turn the anchor. Generally, the higher the torque value the more stable the soil. This gives soil and structural engineers an accurate indication of the load-bearing capacity of the helical anchors.

Common Residential Home Foundations

Homeowners don’t often think about the foundations of their home, but those foundations are critical components of any home, as they bear the entire load of the structure above. Foundations also have another critical function, in that they must prevent groundwater and soil vapors from penetrating into the home’s interior. When you’re trying to decide what kind of foundation your new home should have, there are four choices available to you, and each has advantages and disadvantages.

Excavation Contractor – What Does the Business Involve?

What seems like a straightforward business, drilling and excavating, actually has a lot of parts to it that all have to work together. Here are some of the key aspects of running a business like ours.

Soil Improvements Provide Strength and Control Groundwater for Excavation

Before excavation and construction can begin at a construction site, ground improvements must be done to manage groundwater and improve soil strength. Otherwise the site may not be able to provide adequate support for the planned foundation. There are several methods which can be used to accomplish this, depending on the conditions of the soil. To determine the need to make soil improvements prior to the work of the excavating contractor, it may be necessary to consult with a civil engineer.

Foundations: Building a Strong Base for Your Building

The long-term structural stability of any building depends on having a well-built foundation in place. In a region subject to earthquakes, it is especially important for a highly reputable Bay Area excavating company to set the stage for that strong foundation. It is easy to build something passable, but it takes a well managed, well supervised and well executed excavation to build a foundation that will stand the test of time.

The Five Steps of Excavation

Construction site excavation can be a very difficult process sometimes, in the Bay Area and elsewhere, whether it’s for a home, an office building, or for public construction projects like road buildings. Soil conditions can cause problems, close quarters with other buildings can create logistical issues, and any number of other obstacles can pop up to hinder the process.

Preparing Your Site for Excavation!

Before any Bay Area home or office building can be constructed on a given site, excavation and site preparation must take place. Without this important precursor to construction, it would be impossible to install an appropriate foundation upon which any permanent structure should be built.
