Design Example: Maintaining Level of an Embankment01:19

Design Example: Maintaining Level of an Embankment

508
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Differential Leveling01:12

Differential Leveling

869
Differential leveling is a precise method in surveying used to determine the elevation difference between two points. Its primary goal is to establish accurate vertical measurements to create level surfaces or grade lines critical for designing and constructing infrastructures such as roads, bridges, and buildings.The procedure for differential leveling begins with setting up and leveling the instrument at a point where the benchmark can be seen. The level rod is held on the benchmark (BM), and...

Design Example: Measuring Distance Between Two Points with Obstructions

500
When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...

Design Example: Alignment of a Road Line Using GIS

402
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Electronic Distance Measuring Instruments01:30

Electronic Distance Measuring Instruments

660
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

Profile Leveling and Cross Sections01:26

Profile Leveling and Cross Sections

2.0K
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Area of Science:

  • Public Health
  • Health Services Research
  • Program Evaluation

Background:

  • State tobacco prevention and control programs (TCPs) need robust infrastructure to meet national tobacco reduction goals.
  • Existing literature lacks valid and reliable measures for monitoring TCP infrastructure, hindering planning and evaluation.
  • The Component Model of Infrastructure (CMI) offers a framework for developing and maintaining TCP infrastructure.

Purpose of the Study:

  • To describe the development of measures for the Component Model of Infrastructure (CMI).
  • To evaluate the utility and predictive capability of CMI measures through a pilot test.
  • To assess the face validity, clarity, and ease of use of the CMI measurement tool.

Main Methods:

  • Development of CMI component measures.
  • Pilot testing of the CMI tool with nine state TCP managers.
  • Assessment of tool's face validity, clarity, and usability.

Main Results:

  • The CMI measurement tool demonstrated good face validity.
  • Pilot test participants found the tool clear and easy to follow.
  • The CMI tool provides valuable data for public health efforts and program sustainability.

Conclusions:

  • The CMI measurement tool can enhance public health program planning and evaluation.
  • This tool is particularly useful in funding-constrained environments.
  • CMI facilitates better understanding of infrastructure's role in program outcomes and sustainability.
