The technical aspects of landscape architecture are commonly referred to as site engineering or landscape technology. In this book the term design realization will be used. Design realization is generally concerned with site grading and drainage; road and trail design; landscape planting; and structural aspects of pavement, walls, decks, and special features such as fountains. Design realization can extend to the more general realm of the preparation of the technical drawings and details that translate design drawings of Schematic and Design Development Phases (the illustrative plan, perspective three-dimensional drawings, and sections) into the types of drawings a contractor would use to construct the project. In this chapter we will review the subjects and the technical aspects that a landscape architect would have all or some responsibility for preparing the drawings used to guide construction.
