There is a free course offered by Construct-Ed called Layout Part One: Establishing Elevations, its a free course that takes you through the whole process of understanding decimals to shooting elevations. There is also a quiz at the end, click this link Layout Part One: Establishing Elevations to start the course!
•Set up tripod
•Set & level
•Find a benchmark
•Place grade Stick on benchmark
•Shoot grade stick to determine elevation above benchmark.
•Determine the height of your instrument (HI)
To find your HI (height of Instrument)
Start from a benchmark-Known elevation point + measurement on grade stick
IE: benchmark 4320 + 5.80 (decimal Stick)
Your HI= 4325.80
If your building datum elevation is 4320 (which is equal to level one finish floor)
then 4320= 100.
If your HI is 4325.80 this equals 105.80, so you are 5.80 above finish floor.
If you are trying to establish elevation, lets say 105.00 on core walls for reference. Then you would shoot a mark on the wall (this is level with your instrument) and measure .80 (9-9/16”) below the mark to be at elevation 105.00.

Using a decimal stick is quicker to convert numbers vs. using feet and inches stick.
A cheap calculator and to know decimals is all you need to make elevation layout a breeze. (need inches to decimal converter: click here)

In this weeks tip we will upload our SketchUp model into Sketchfab which allows you to view in VR. We will be using NOON VR googles to view. It will only get better! Being able to place yourself in the model, to walk and look through VR will give us a whole new experience viewing 3d models. Enjoy!

This week we will be going over a five part series to create a sequence and schedule plan in Bluebeam Revu. This is to help you create a visual sequencing and scheduling plan that's easier to read and understand than a typical schedule in Excel.
This weeks tip we will be adding pictures to your SketchUp model, this can be very useful to add details like reinforcing, specialty or complex design details to create a combined drawing for your crew.
In this weeks tip we will walk through the four types of corner lacing (or as we call it" log cabin ") on a handset wall.
Today we are going to add metal decking as the support for a concrete lid on a tunnel .
