Survey

Railway projects require proper and accurate survey for the construction of railway lines between two locations. ACRC provides the following types of Surveys for suitable alignment of the railway line by using advanced and up to date survey equipment such as Digital Global Positioning System or GPS Station, Total Station, and Digital Level Machine:

• Viability of New Railway line construction (Population living, features, and structures list, the geometry of the site, Expected estimation for revenue and etc),
• Marking of Tentative Alignments (several options with considering economic, short, straight, a smaller number of structures, good connection of important location,
• Reconnaissance Survey (surrounding area of alignment 100 m, water table, soil survey, number of crossing points, notes about the structure numbers and details, number of curves, the gradient of the site, availability of construction materials, availability of skill and Unskill labors, Hydrological data and etc,
• Selection and Good Alignment (Short, economical, good revenue, the minimum number of structures, connect important area,
• Establishment of Standard and Permanent Bench Marks by GPS Station (construction of BM, Installation at the site, observation of coordinates by Digital Global Positioning System,
• Traverse Surveying and Calculation and Balancing of Traverse (Establishment of BM networks or control points between Bench Marks, observation of coordinates, Calculation of Travers, checking and balancing of the traverse,
• Detailed Engineering Survey (Topographic survey, cross-section survey, longitudinal survey, structure survey,
• Final Survey Report (Project Introduction, Necessity of Project, Justification of Alignment, Benchmarks, Detail of Alignments such as length, Area, number of bridges, culverts, crossing, Tunnel and etc., Structure report, Site picture, Survey data, and Recommendation of Project).
