Urban Development Department Tender

Schedule 1:Survey, soil investigation, Design, Drawing & Documentation work

Conducting a detailed topographic survey for the alignment of water and sewer pipelines along existing or new roads, as well as in forest areas utilising exsisting forest cart tracks. This includes capturing longitudinal (L-section) and cross-sectional profiles at every 30-meter interval within the Right of Way (ROW), with a minimum of 10 spot levels per cross section. The survey will document all existing features within the ROW, such as electric and telephone lines, encroachments, structures, streams, and rivers. Primary total station control points will be connected using G.I.S. benchmarks or other available departmental benchmarks, utilizing an auto level. The collected data will be used to prepare an AutoCAD plan. Additionally, the surveyor must establish and mark precise benchmarks at suitable intervals to guide the design and construction phases. The survey will also include mapping of properties, GIS-based consumer mapping of water and sewer connections, asset plotting on GIS maps, and any additional tasks specified by the Employer’s Representative.

Topographic Survey with a grid area of 15MX15M, includes all features such as structures (bridges, culverts etc.) utilities, existing roads, electric and telephone installations (both O/H as well as underground), huts, buildings, fencing and trees, oil, water and gas lines etc. using Total Station and develop a drawing in AUTO CAD format using the layering system and Geo referencing including supply of detailed drawings (with DGPS) in appropriate scale in size complete in all respect.
