Road Survey

Civil Scope of Work

1.      Access/Bauxite transportation road, Bridges, and culvert from highway to hill top and Neary by Tikri Railway siding

Visual site inspection of the proposed Road alignment at regular intervals.

• To conduct foot by foot reconnaissance survey along the proposed alignments, duly checking various geographical features, site constraints such as existing roads, railway lines, power lines etc. and to assess modification to the proposed alignment as per site conditions; To collect GPS control coordinates along the proposed / possible alignments and spot levels to establish X, Y, Z co-ordinates along alignment.
• Bridge Survey
1. Inspection of existing Culverts/Bridges.
2. Assessment of condition of Culverts/Bridge
• Suggestions on rectifications / refurbishments or replacement of bridges or Other
• Preparation and submission of Road detailed inspection report.
• Budgetary Cost estimate for road upgradation.
• Identifying the problems and conditions of proposed Road alignment.
• Road, Bridge, culvert design shall be finalized based upon aesthetics, geotechnical studies, cost effectiveness and ease of construction.
• Preparation of general arrangement drawing showing all dimensions and details of Road and Assisting AEL to getting Approval from concerned Authority. The GAD shall be supplemented by preliminary design in respect of Longitudinal section, cross section of road etc.

Road Survey 

• To conduct Route Survey (By Total Station) for the final approved alignment based on reconnaissance survey duly collecting all the topographical features within the ROW covering the corridor of 50 mts such as;
• Existing Roads & Crossings etc;
• Buildings, Temples, Church, Forest areas, village boundaries etc;
• Roads, Canals, Streams, Major rivers, Pond, Graveyard, existing infrastructure if any etc;
• HT/LT Electrical lines, Telephone lines etc;
• To Design of Alignment duly accounting for;
