Soil liquefaction is a geological phenomenon that changes the structure of the Earth’s soil. External stressors loosen the soil particles, changing the ground into a less stable base for buildings and other structures. Soil liquefaction presents risks to construction companies building in high-soil liquefaction areas, such as California. If builders construct on top of loose…
A geologist ensures the safety of the ground you are building on by testing for groundwater, percolation, soil gas, and other government-required tests. Hiring a geologist saves construction projects time and money by creating scientifically-backed design recommendations for anything from a septic tank to the foundation of a large building. If you want to…
Accessory Dwelling Unit (ADU) refers to a secondary dwelling unit found on the same lot as a primary unit (a home). Examples include house extensions, garages, and garage conversions, either attached to or detached from the primary unit. If you live in the Los Angeles or Glendale areas, a critical part of the permitting process…
If you’re planning any construction project, chances are you’ll want to consult an engineering geologist. From geological hazard assessments to soil liquefaction, the work of engineering geologists ensures that your new construction, public works project, or engineering venture is on solid ground. What is the Main Goal of Engineering Geology? Engineering geology seeks to…
The California Geological Survey has brought to light new information about Hollywood quake faults that reminds many of Sylmar in 1971.
If you’re involved in a construction project or building rehab, chances are you’ve heard an important phrase floating around: methane barrier installation. These three words hint at a specific problem that the Los Angeles Department of Building and Safety takes incredibly seriously. Methane soil gas intrusion poses an extremely dangerous risk to occupants of a…
On the eastern slope of the Sierras, just three hours north of Los Angeles, lies the deceptively-named “Alabama Hills” — a wonder of geology and Earth science. Sitting around 5,300 feet in elevation, this rolling vista of rock formations, classic Western landscapes, and spectacular natural weathered arches is a treat for anyone who visits (not…
Wildfires have a significant impact on the properties of the soil. The heat of the fire burns away all of the vegetation and organic matter on the surface of the soil, which makes some nutrients more readily available to the soil while turning others into gases that are lost (chiefly nitrogen). In addition, the heat…
Without a solid foundation, your property is in danger of collapsing or moving in place. No one likes losing an investment, which is why it’s important to use foundation investigations to determine the overall health of your property. In most cases, foundation engineering reports come along with soil engineering reports, and most geotechnical engineers can…
Builders everywhere rely on environmental engineers to make sure their building sites are safe and up to code. Learn all about these skilled professionals and what makes environmental engineers so special. Examples of Environmental Engineering Duties Environmental engineers take years to learn the ins and outs of the trade, and these professionals end up…
