Civil Engineering on a Mount Washington Hillside

Civil Engineering on a Mount Washington Hillside #CivilEngineer

Today is time to play catch up with some Civil Engineering projects. Catch up if you count we just got these projects to start a few hours ago.

First on the list are some revisions to the apartment project we are working on in Glendale near the Americana. It wouldn’t be too much but the developer is trying to have this turned around fast. What fun, I get to speed through the changes the Architect made while adding more notes and details that the Civil Engineering plan checker wants. We will also be starting on the plans for another project with the same developer for a project in Venice on the same rush schedule. Now all we need is that updated survey.

As I try to plan out the day I try to go in some order of what needs to be done and what will take the shortest to longest to complete. Right now everything is in an extreme rush. Also none of the projects are a quick slamdunk to finish. But there really is nothing that puts my brain into gear better than some hillside grading. This project in Mount Washington is going for an alternate design. The original grading plan showed a future lot line adjustment so we end up grading less of the lot. The alternate design will focus on grading the entire lot as is up to the existing property line. One we reach the property line we will transition from a 1:1 cut slope into the existing terrain. Things are never as easy as they appear.

First I had to find where the existing slope goes from 1:1 to steeper. That sets the toe of slope. Then I grade upwards until daylight is reached. Going smooth so far. This is only going smoothly because I already graded this previously and see where the toe most likely will be. In fact it looks like the general grading just about works out as I throw a bunch of proposed contours and trim where the daylight occurs. Next is figuring out how to smoothly transition the 1:1 cut slope to the existing contours. I then make an imaginary transition area and things look good. Next I will create the 3D model to get the earthwork cut and fill numbers. That is the final test to make sure the entire slope is adhering to the Soil Engineer recommendations of only a 1:1 cut slope and absolutely no fill onsite. The model is also a good double check to make sure the 1:1 cut slope actually works.

Nothing like some Civil Engineering on a nice Southern California day.
