Thanlyin-Bago Topographic Survey (Lot 3) under ADB TA-8987 MYA: Improving Road Network Management

As part of the evaluation of the pilot sub-projects for TABSBT the project has engaged ADB approved consultants to undertake geotechnical and topographic surveys on the road between Thanlyin and Bago. This road is under the care and control of Oriental Highways and it is proposed to be rehabilitated under the ADB loan.

Cores will be obtained from the edge of the pavement and also along the center-line so that we obtain a good understanding of the condition of the formation which we understand may be in a poor condition.

The key tasks of the consultant team include:

. Enable the preliminary design of hydraulic structures

. Alignment design

. Review of the topography, existing records, plans, maps, appropriate instructions, standards, technical and legal regulations

. Identify the current centreline

. Creation of DTM and topographic layout of the central line of existing centreline alignment

. Identify the natural obstacles and physical object

. Identify the location and level of the power lines and electrical poles in the sections along the alignment

. Identify the level of the natural ground along the river streams, on 50 m width either side of the existing alignment centre line at 10 m intervals

. Daily report describing in detail the progress of the works.
