The survey of 63 kilometres of road alignment through urban, peri-urban and virgin territory. This survey traversed through rolling hills at the start, flatter, sugar cane covered swathes in the low veld and then climbed steeply up to the Lomahasha border for the second half. With stringent health and safety regulations to be observed as well as the military permissions and situation along the Mozambique/Swaziland border the survey was a complicated logistical exercise. Total stations were used extensively in the five large river crossings surveyed with several of these infested with Hippo’s, crocodiles and snakes. The whole survey was riddled with complications pertaining to access and dangerous wild life.
The culverts were often large and inaccessible with the weather rainy and adding to accessing these culverts being a challenge.
The survey was conducted on LO31 Clark 1880 system so that the existing LiDAR imagery as well as the local cadastre could be overlaid directly onto the survey. With the acquisition of this existing data, the full topographical strip survey at 80 metres wide, 500 metre wide river crossings and bathy surveys of the five rivers as well as the induction health and safety training of all personnel, from start to finish Route Geographic Consultants took 2.5 months to complete the works to the clients high standards.
A challenging survey with a very supportive and attentive client successfully completed to the RGC high standards expected.
