Project Overview

These surveys are required for design purposes of either the upgrading of an existing road or pipe, or the building of a new road or pipe line.Typical examples include access roads and clustered water reticulation projects for rural communities. High specification roads are surveyed to the stringent TMH11 standard as published by SANRAL (SA National Roads Agency Limited). In addition to undertaking the road and control surveys, NPM is also contracted to perform check surveyors for strip surveys undertaken on SANRAL roads.

Project Overview

Hydrographic surveys are carried out on dams or rivers where the profile of the dam or river bed is modelled for volume and design purposes. The surveys are carried out using a boat or kayak fitted with depth sounding equipment linked to a GPS receiver. NPM completed the survey of 18 dams within a 6 week period during 2011. In 2012, NPM was involved in the survey of the river bed profile of the Fish River near Port Alfred. This survey was particularly challenging in terms of access, wildlife (hippo) and heavy rainfall during the survey campaign. River profiles have also been surveyed in Fort Beaufort and Cala.
