LARE LARE Construction Documentation 2 — Questions and Answers
Question 1: Which drawing type typically shows the horizontal arrangement of site elements at a specific elevation cut?
- Elevation drawing
- Plan view drawing (Correct answer)
- Section drawing
- Detail drawing
Correct answer: Plan view drawing
A plan view drawing is a top-down horizontal cut through a site or structure showing layout at a designated elevation.
Question 2: On a grading plan, what does a dashed contour line typically indicate?
- Existing grade contours (Correct answer)
- Proposed grade contours
- Drainage swales
- Underground utilities
Correct answer: Existing grade contours
Dashed contour lines on grading plans conventionally represent existing grade conditions before construction.
Question 3: A construction document set includes a 'legend' sheet primarily to:
- List the project schedule
- Define symbols, abbreviations, and line types used throughout the documents (Correct answer)
- Show the site location on a regional map
- List contact information for all consultants
Correct answer: Define symbols, abbreviations, and line types used throughout the documents
A legend sheet defines all graphic symbols, abbreviations, and line types so readers can correctly interpret every sheet in the set.
Question 4: What is the purpose of a 'spot elevation' notation on a site plan?
- To indicate the highest point on the site
- To call out the finished elevation at a specific point (Correct answer)
- To show the depth of an excavation
- To mark utility invert elevations only
Correct answer: To call out the finished elevation at a specific point
Spot elevations provide the precise finished grade at a specific point, supplementing contour information for critical locations.
Question 5: Which document in a construction set typically governs material quality, installation standards, and testing requirements?
- Sheet notes
- Technical specifications (Correct answer)
- General conditions
- Bid form
Correct answer: Technical specifications
Technical specifications (Divisions 01–49 in MasterFormat) set quality standards, material requirements, and installation and testing criteria.
Question 6: A 'bench mark' (BM) shown on a grading plan is used to:
- Mark the location of site furnishings
- Establish a fixed reference elevation for all site measurements (Correct answer)
- Indicate the top of a retaining wall
- Show the 100-year flood elevation
Correct answer: Establish a fixed reference elevation for all site measurements
A bench mark is a permanent reference point of known elevation from which all other site elevations are measured during construction.
Question 7: When a landscape architect adds a 'keynote' to a plan, they are:
- Highlighting the most important design feature
- Assigning a numbered reference that links plan elements to a written legend or specifications (Correct answer)
- Noting the contractor's contact information
- Calling out the plant common name
Correct answer: Assigning a numbered reference that links plan elements to a written legend or specifications
Keynotes use numbered or lettered callouts on drawings that correspond to descriptions in a separate legend, reducing repetitive notation on plan sheets.
