Engineering maps: These maps are typically created for specific projects to aid site location, planning, and construction activities. Assess this statement.
-
ACorrect: project-specific maps supporting location and construction
-
BIncorrect: engineering maps are only for recreational hiking
-
CIncorrect: they show artwork only, without measurements
-
DIncorrect: they are identical to nautical charts
-
ECorrect only when the project is purely architectural interiors
Answer
Correct Answer: Correct: project-specific maps supporting location and construction
Explanation
Introduction / Context:Engineering maps support the lifecycle of infrastructure and site development: feasibility, design, permitting, construction, and maintenance. They differ from general-purpose topographic maps by focusing on features relevant to engineering decisions and construction logistics.
Given Data / Assumptions:
- Use cases include roads, utilities, drainage, buildings, and earthworks.
- Accuracy and currentness are critical for staking and inspection.
- Content often integrates survey control, elevations, and legal boundaries.
Concept / Approach:Engineering maps emphasize practical information: benchmarks, coordinate systems, contour intervals, property lines, easements, right-of-way limits, utility routes, and construction phases. They aid location selection, grading design, and field execution by contractors and inspectors.
Step-by-Step Solution:
Identify project scope and mapping needs (topography, parcels, utilities).Compile survey data into base mapping with correct datums and scales.Use maps during design reviews and for construction staking and as-builts.Verification / Alternative check:Review any civil project bid set; you will find plan/profile sheets and key maps explicitly created for that project’s location and construction details, confirming the statement.
Why Other Options Are Wrong:
- Recreational use (option B) is outside the primary engineering purpose.
- Artwork without measurements (option C) is not suitable for engineering.
- Nautical charts (option D) serve marine navigation, not land projects.
- Limiting to interior architecture (option E) is too narrow—civil and site projects dominate.
Common Pitfalls:Using outdated base maps; mixing datums and coordinate references; omitting utility markouts leading to conflicts in the field.
Final Answer:Correct: project-specific maps supporting location and construction
