Completing Your Specification  for


Step 1. Select your desired specification, Level I, II, III, or IV. Open the file and begin creating your greenhouse specification.

Step 2. [Script highlighted in RED and enclosed in brackets are intended to be instructions for that portion of the specifications]. After completing the task, which usually requires making a selection delete the red script from the specification.

Step 3. Scripts highlighted in BLUE are selection items. Change the item you want to use to BLACK text and delete all the other blue text in that area of the specification.

Step 4. Add the project name at the top of each page and the correct page numbering system at the bottom.

Step 5. Refer to the value engineering sections to assist you in creating a greenhouse using our standard styles, sizes, and dimensions.

Step 6. Delete this page from your new specification and copy and paste it into your master specification document.
