You are employed by a local surveying company and have been approached by the local authority to carry out a topographic survey of a plot of land at the Future Skills Campus, Salford. The topographic survey is required for the initial and detailed design process. Part of the requirement is to set a control network of stations that can be used for future surveys and to aid in the setting out once construction commences.
You are required to produce a report on the plot for submission to the client including the following:
- An explanation of the types of control networks that are available
- A comparison of the accuracy of the network compared to national standards
- An explanation of the process of conducting a topographic survey
- A critical analysis of the accuracy achieved including the influence on the topographic survey
The client requires the network to be robust with a minimum of five stations.
Undertake the following:
- Carry out a closed traverse of the station network which includes heights, internal angles and line
lengths.
Calculate from the survey the corrected eastings, northings and heights of each of the stations.
