To strengthen national security and for maintaining law and order, it is imperative that proper mechanisms are put in place which is efficient and user friendly. The existing infrastructures were not adequate for efficient functioning of the checkpoints given the importance of its services. Further, different government agencies have installed their respective counter randomly which is cumbersome to the commuters.
Therefore, Geotechnical study of the area for the establishment of check point was done by the APECS intended to serve not only for facilitating the enhancement of security, but also to enhance effective and efficient delivery of the services depicting the country’s image and status to outsiders
Following were the major scope of the assignment:
- Undertake field trips to the identified area and carry out additional field surveys to confirm desk study interpretation and gather supplementary data.
- Identify, assess and prepare instability inventory maps (landslides, erosion, debris flow, scouring, toe erosion, creep, subsidence, land degradation, rock fall, planner failure, wedge failure, toppling etc.)
- Survey, Identify, assess and prepare the slope map of the study area indicating the slope classification and level of hazards posed by the topography.
- Survey, Identify, assess and prepare the geomorphologic maps for the instabilities.
- Survey, Identify, assess and mark on map all water bodies (springs, creek, stream both seasonal and perennial, seepages, rivers etc) that have impacts on the study area.
- Assess the impacts on land use with particular emphasis on critical watershed areas, loss of agricultural and forest land, settlement/movement/cracks on the land use.
- Identify and assess the strength of geological materials by conducting necessary field and laboratory tests and analysis.
- Assess the correlations between the instabilities and geology (rock type, soil and deposits), topography (slopes), land use, hydrology (rainfall, seepages, and ground water) and determine the most significant factors that are responsible for causing the instabilities.
- Slope stability analysis of soil and rock slopes
- Determine if the slope problems are self-generated or imposed.
- Inspect high risk locations to define potential engineering solutions.
- Determine requirements for engineering structures such as retaining walls, Landscaping and complementary bioengineering applications and provide to the client final report comprising of detailed hazard map, design, drawings, mitigation plan, detailed BoQ and cost estimate.
