Scope of Works for Topographic Survey
Introduction
In order to fulfill the requirement of the client for Samanea Mixed Development PH-2 Project
at Tangerang New Industry City, Cikupa, Tangerang, Indonesia,the topographic survey for area
approximately 9.92 HA,are required primarily to assess the information on existing boundary
markers, encroachment public road, objects, fence boundaries, electric poles, other utilities and
topographic site conditions. The work will be supervised by qualified surveyor/engineer
experienced in the type of work to be carried out. The program comprises the following tasks:
Survey Work
a. Set the vertical points with reference by GNSS Static survey method from according to
government control point.
b. The accuracy of horizontal distance shall be better than 3rd order class 1 (1:10,000) and the
allowable error of elevation shall not exceed 12√K (km) in unit of mm.
c. Determine site boundary with co-ordinates pointed out by the client representative.
d. Determine spot levels across the project area at about 30 m spacing or as appropriate.
e. Determine the ground levels at least 10 m outside boundary perimeter.
f. Locate all existing buildings, objects and facilities in the area and at least 10 m outside site
boundary perimeter including roads, junctions with names, nearby building boundary, drainages
with invert level (both temporary and permanent), electricity and telephone poles.
g. Locate trees positions, shrubs and types with diameter greater than 0.20 m.
Report and Drawings
Two copies of report will be submitted together with a soft copy in File.dwg format. The
following information will be included:
a. Introduction and description of works undertaken.
b. Calculation of traverse and leveling in tabular forms.
c. 2 copies of Plan Drawings on UTM grid showing all horizontal coordinates and level with
appropriate scale on A1 paper and soft file in AUTOCAD R2000 format.
Timing
The survey team will be mobilized within 5 days after receiving the work order. All
works including a final report and drawing will be completed in approximately 20 days
after mobilization.
