Landscape
architects work at different levels, from simple residential dwellings
, real estate development firms starting new projects to municipalities
constructing airports or park and they often are involved with
the development of a site from its conception.
Working
with architects, surveyors, and engineers, landscape architects
help determine the best arrangement of roads and buildings. They
also collaborate with environmental scientists, foresters, and
other professionals to find the best way to conserve or restore
natural resources. Once these decisions are made, landscape architects
create detailed plans indicating new topography,
vegetation, walkways, and other landscaping details, such as fountains
and decorative features.
In
planning a site, landscape architects first consider the nature
and purpose of the project and the funds available. They
analyze the natural elements of the site, such as the climate,
soil, slope of the land, drainage, and vegetation; observe where
sunlight falls on the site at different times of the day and examine
the site from various angles; and assess the effect of existing
buildings, roads, walkways, and utilities on the project.
After
studying and analyzing the site, landscape architects prepare
a preliminary design. To account for the needs of the client as
well as the conditions at the site, they frequently make changes
before a final design is approved. They
also take into account any local authority regulations, such as
those protecting wetlands or historic resources. In preparing
designs, computer-aided design (CAD) has become an essential tool
for most landscape architects. Many landscape architects also
use video simulation to help clients envision the proposed ideas
and plans. For larger scale site planning, landscape architects
also use geographic information systems technology, a computer
mapping system.
Throughout
all phases of the planning and design, landscape architects consult
with other professionals involved in the project. Once the design
is complete, they prepare a proposal for the client. They
produce detailed plans of the site, including written reports,
sketches, models, photographs, land-use studies, and cost estimates,
and submit them for approval by the client and by regulatory agencies.
When the plans are approved, landscape architects prepare working
drawings showing all existing and proposed features. They also
outline in detail the methods of construction and draw up a list
of necessary materials. Although many landscape architects monitor
the installation of their design, the developer’s project
general contractor or a landscape contractor usually directs the
actual construction and installation of plantings.
