Section 1: Landscape Planning, Design, and Site Preparation
Question 1
Before beginning a landscaping project, what should a contractor do
first to establish the property's existing conditions and identify
potential obstacles?
A. Begin removing vegetation and excavating the site.
B. Review the project plans, inspect the site, and identify existing
utilities and site conditions.
C. Install the irrigation system before conducting measurements.
D. Order all plant materials based solely on the estimated project area.
,Rationale: Reviewing plans and inspecting the site establish the
project's scope and identify conditions that could affect construction.
The contractor should locate underground utilities, assess slopes,
identify existing structures, and verify dimensions before excavation or
installation. This helps prevent utility damage, design conflicts,
unnecessary costs, and construction delays.
Question 2
Which document typically identifies the location of trees, shrubs,
ground covers, and other plant materials in a landscape project?
A. Electrical load schedule.
B. Plumbing riser diagram.
C. Landscape planting plan.
D. Concrete mix design.
Rationale: A landscape planting plan shows the intended locations,
spacing, and often the species or varieties of plant materials. It may
include plant schedules, symbols, quantities, and planting details.
Contractors use it to determine plant placement and coordinate
planting with irrigation, drainage, structures, and other landscape
features.
Question 3
,What is the primary purpose of a site grading plan?
A. Identify the color of every plant.
B. Establish the irrigation controller's programming schedule.
C. Determine the types of fertilizer required.
D. Establish finished elevations and direct surface water
appropriately.
Rationale: A grading plan establishes existing and proposed elevations,
slopes, and drainage patterns. Proper grading helps move water away
from buildings and toward approved drainage areas. Incorrect grading
can cause ponding, erosion, foundation problems, and damage to
neighboring properties.
Question 4
A contractor discovers that the actual site elevations differ significantly
from the approved landscape plans. What is the most appropriate
action?
A. Ignore the difference and install the landscape according to visual
preference.
B. Add soil until the site appears level.
, C. Notify the appropriate project representative and resolve the
discrepancy before proceeding with affected work.
D. Change the drainage pattern without authorization.
Rationale: Significant elevation differences may affect drainage,
accessibility, retaining walls, irrigation, and finished construction
elevations. The contractor should document the discrepancy and obtain
direction or revised plans as required before proceeding. Unapproved
changes can create safety issues, defective work, disputes, and costly
rework.
Question 5
What is the main purpose of protecting existing trees during landscape
construction?
A. Prevent all sunlight from reaching the tree.
B. Prevent damage to roots, trunks, branches, and the surrounding
soil.
C. Eliminate the need for irrigation.
D. Increase soil compaction around the trunk.
Rationale: Construction activities can damage trees through excavation,
root cutting, soil compaction, chemical exposure, and physical injury.
