Different survey required for new road project

-Map Study:

With the help of available topographic maps are.

-Reconnaissance Survey:

A general idea of a topography and other feature, field identification of soils and survey of construction materials, by an on the spot inspection of the site.

-Preliminary Survey:

Topographic details a soil survey along alternate alignments, consideration of geometric design and other requirements of alignment, preparation of plans and comparison of alternate route and selection of final alignment.

-Location of final alignment:

Transfer of the alignment from the drawing to the ground by driving pegs along the centerline of finally chosen alignment, setting out geometric design elements by location of target points, ax points, circular and transition curves, the elevation of center line and superelevation details.

-Detailed Survey:

Survey of the highway construction work for the preparation of longitudinal and cross-sections, computations of earthwork quantities and checking details of geometric design elements.

-Materials Survey:

Survey of construction materials, their collection, and testing.

-Design:

Design details of embankment and cut slops, the foundation of embankments and bridges and pavement layers.

-Earth Work:

Excavations for highway cutting and drainage system, construction of embankments.

-Pavement Construction:

Preparation of sub-grade, construction of sub-base and surface courses.

-Construction Controls:

Quality control tests during different stage of constructions and check for the finished road a surface such as unevenness, camber, superelevation and extra widening of pavements at curves.
