NNP1-MS-RW038-A1
OBAYASHI CORPORATION Page 10 Revision: A1 December 2014
5.1 Survey Work
Figure-3 Conceptual drawing of survey
Firstly temporary benchmarks for elevation and coordinate are established at
approximately 100m intervals.
Secondly, the centerline of the road alignment is identified on site with offset pegging
considering the design alignment. After completion of the centerline survey, the cross
section survey is carried out by minimum 20~25m intervals. And then, based on cross
section survey results, embankment and excavation area can be identified on site.
In case the original design alignment will not be suitable for the actual site condition, the
design alignment will be modified and corrected inside the designated area by the Owner.
Survey instruments shall be calibrated in accordance with the section 5.3.3 testing
equipment and facilities of the Quality Assurance Program (Document No. NNP1-PRG-
DrQAP-A3) in the NNP1-PCL-00086, dated 16th Jan. 2014.

disposed. Any suitable topsoil which is free from roots and vegetable matter
shall be stockpiled at the specified area and used for planting and/or
embankment. The specified area is to be informed to the Owner.
2) It seems that stumps are not deep and long considering the actual site
conditions, thus all of them can be basically removed and replaced with
suitable material. In case that it is difficult to remove all, its countermeasure
will be discussed with the Owner.
3) Removed topsoil which is suitable material for the construction will be stored at
suitable area along the road where it is distinguished in order to prevent mixing
with unsuitable soil.
4) Keeping clearance to the minimum area is required for the proposed project
activity. The extent of vegetation clearance at each site shall be surveyed and
clearly marked prior to the commencement of clearing. In case that the
existing paddy field is within project area, the ridge of paddy field is to be sifted
and irrigation canal shall be diverted.
5) When spoil moves down slope occasionally, the Contractor will make their
best efforts to carefully remove it without disturbing existing vegetation or
natural slope and dispose of it appropriately.
