Marking and layout is the third step in building your deck. The layout is possibly the most important step after you have made the decision to proceed. The placement of the footings is critical to the location of the support posts, which will ultimately make your deck a safe and enjoyable place to enjoy the outdoors, and keep it from falling down!
Even though there is room for error in measuring the location of the footings, success comes from striving for accuracy, therefore measure to the 1/8th of an inch. This layout is simple and can easily be completed by any level of DIYer. Mistakes can be corrected at a later part of the project if necessary. These mistakes however, will add time and money to your deck project if left uncorrected.
To set up for this task, gather your drawings, tape measure, marking tools, level, all of your equipment, and put them on a site worktable for easy reference and a place to find them. A paperweight of tools and other heavy objects will keep the plans in place if the wind begins to blow.
