HIGHWAY ENGINEERING

Knowledge – Capability – scope of Roads and Highway

Our Projects in Highways, Rural Roads and Urban streets involve a number work components.

• Undertaking detailed reconnaissance, an overall aerial survey/ photogrametry in case of green corridor/ ribbon development and important findings during the reconnaissance.
• Reviewing early feasibility/DPR reports; review of pavement designs, GAD of major structures, etc.
• Review of the available information such as survey data, geotechnical & hydrology reports, traffic data, general arrangement drawings prepared in the DPR/feasibility.
• Carrying out Inventory and condition surveys for project road, bridges cross drainage structures, and all other structures.
• Field Investigation including detail geotechnical, existing road asset, pavement crust, Hydrology, Environmental and social impact.
  • Taking test pits to assess the effectiveness of existing pavement.
  • Carrying out material investigations, including identification of borrow areas and quarries, to assess the suitability of materials in road construction and to facilitate design of some of the road elements (e.g. CBR for design of new pavement).
  • Carrying out Topographic Surveys/ Aerial/ Mobile Lidar/ DGPS/ Total station within the ROW.
  • Carrying out BBD surveys
  • Subgrade investigations
• Establishing Design Standards and Typical Cross-sections (Review of design standards and typical cross-sections given in RFP/feasibility report and comments on its feasibility).
• Carrying out Preliminary Designs of geometrically deficient stretches.
  • Estimation of design lane loading from VDFs computed.
  • Pavement for new construction and Review of Pavement designs
  • Overlay and rehabilitation measures for existing pavement based on sample deflection data.
  • Rehabilitation/widening/reconstruction of cross drainage and other structures – minor and major bridges etc. Review of GAD’s.
  • Preparation of drawings for new CD structures and other structures – minor and major bridges etc.
• Preparation of drawings for elevated corridor/ flyovers, underpasses and overpasses.
• Preparation of drawings for earth retaining structures as per individual site requirement.
• Pedestrian crossings.
• Intersections
• Drainage design.
• Roadside facilities like truck layby, bus bay, other appurtenances.
• Design of Traffic Safety features.
• Design of toll plaza.
• Optimization and value engineering proposals for faster construction and/or cost reduction.
• Designs for environmental and social concerns, if any.
• Land Acquisition Plan and Utilities Relocation Plan.
• Environment and social report.
• Preparation of Bills of Quantities (BOQ).
