The Scope of Services include but not limited to the following:
ROAD INFRASTRUCTURE MASTER PLANNING
Planning road networks, their inter connectivity, probable use and relative importance. Priority ranking of roads in a road network based on socio-economic factors.
PRE-FEASIBILITY STUDIES FOR ROUTE SELECTION
Identification of potential corridors, cost effectiveness and durability in terms of maintenance requirements, impact of terrain ranging from the snow capped mountains to the areas of moving sand dunes.
SOILS AND MATERIALS INVESTIGATIONS
Evaluation of the adequacy of soils and materials for highways; determination of the permeability, shear strength, consolidation, grain size, dry density, liquid and plastic limits; field tests including the vane shear test, California bearing ratio test, plate test and nuclear field density equipment tests.
FEASIBILITY STUDIES
Economic studies for assessment of benefits of highway projects, as compared to the total investment. Benefit cost ratio (B/C ratio), determining the economic internal rate of return (EIRR), traffic surveys and their projection over the design life of the project. Feasibility studies of projects on Build-Operate-Transfer (BOT) system where self financing by the private sector is involved.
CONSTRUCTION SUPERVISION OF ROADS/BRIDGES/TUNNELS
Supervision of construction activities to ensure the quality conforming to the contract specifications, progress monitoring and co-ordination between the Client, the Contractor or any other agency involved to ensure timely and successful completion of work.
TRANSPORTATION AND TRAFFIC ENGINEERING
Transportation system surveys, analysis, forecasting, design, traffic flow regulation and administration.
GEOMETRIC DESIGN FOR ROAD WORKS AND INTERCHANGES
Design for pavement widths, horizontal and vertical alignments, slopes, interchanges, acceleration/ deceleration lanes, traffic islands, channelization, junctions and other features.
PAVEMENT DESIGN
Design of pavements to determine thickness of road layers using standard empirical methods such as AASHTO and British Road Note no.31.
