LARE LARE Construction Documentation 4 — Questions and Answers
Question 1: A 'cross-section' drawing is most useful for communicating:
- Plant spacing across a planting bed
- Grade changes and vertical relationships through a cut plane (Correct answer)
- Property boundary dimensions
- North orientation of the site
Correct answer: Grade changes and vertical relationships through a cut plane
Cross-sections cut through the site at a specified line to reveal vertical grade relationships, slopes, and subsurface conditions that cannot be shown on a plan view.
Question 2: What is the primary role of 'general notes' on a construction drawing sheet?
- To describe specific plant species
- To provide project-wide instructions, standards, and code references that apply to that sheet or the whole set (Correct answer)
- To list the contractor's obligations from the contract
- To show the sequence of construction activities
Correct answer: To provide project-wide instructions, standards, and code references that apply to that sheet or the whole set
General notes communicate blanket requirements—such as code compliance, inspection requirements, or material standards—that apply broadly rather than to a single element.
Question 3: Which line type is conventionally used to show hidden or underground features on a site plan?
- Solid continuous line
- Dashed or hidden line (Correct answer)
- Center line
- Break line
Correct answer: Dashed or hidden line
Dashed lines (hidden lines) indicate features that exist below grade or are not visible in the view, such as underground utilities or footing edges.
Question 4: An 'addendum' issued during bidding is used to:
- Award the construction contract
- Formally modify or clarify the construction documents before bids are submitted (Correct answer)
- Document field changes during construction
- Record as-built conditions after construction
Correct answer: Formally modify or clarify the construction documents before bids are submitted
An addendum is a written amendment issued to all bidders before bid submission to correct errors, clarify requirements, or change the scope.
Question 5: On an irrigation plan, 'PR' next to a head symbol typically means:
- Pressure Regulator
- Precipitation Rate (Correct answer)
- Purple Reclaimed water
- Pop-up Rotor
Correct answer: Precipitation Rate
PR on irrigation plans commonly denotes Precipitation Rate, indicating how fast a given sprinkler head applies water in inches per hour.
Question 6: A 'submittal' in the construction process is:
- The contractor's final bill for payment
- A sample, shop drawing, or product data provided by the contractor for the designer's review and approval (Correct answer)
- A request from the owner to change the project scope
- A written claim for additional compensation
Correct answer: A sample, shop drawing, or product data provided by the contractor for the designer's review and approval
Submittals are contractor-provided documents or physical samples that allow the designer to verify materials and methods conform to contract requirements before installation.
Question 7: Which drawing typically shows the horizontal distance between site features and property boundaries?
- Elevation drawing
- Dimension plan or layout plan (Correct answer)
- Grading plan
- Planting plan
Correct answer: Dimension plan or layout plan
A dimension plan or layout plan provides precise horizontal measurements locating all site elements relative to property lines, benchmarks, or other reference points.
