1.4 PROJECT SPECIFICATIONS
The following are the specification to be ascertained in the project:
(i) Traverse must commence on three coordinated (known) controls and closed on another set of three coordinated controls which must be confirmed undisturbed by necessary measurement (control checks).
(ii) Third order theodolite traverse must be run along the route on all turning points at one zero observation and the angular difference from both faces should not be more than thirty seconds (30"), the angular misclosure is determined by 30"√n,
Where ‘n’ is the total number of station observed.
(iii) Establishing traverse points by using pegs together with nails and bottle corks.
(iv) Spirit leveling must commence on a known benchmark and closed back on another known benchmark. Formulae for its misclosure are ±24mm√k, where ‘k’ is the total distance covered in kilometers.
(v) Leveling must be observed at every 25m intervals on the centre line and at 5m intervals on both sides of the centre line for the cross sectioning. Edges of drainage at both sides should be heightened.
(vi) Fixing of relevant features to enhance assessment and necessary composition for good interpretation of plan.
(vii) Setting out curve by using deflection angle method within third other survey.
(viii) The accuracy of the project must fall within the order of the project.
1.5 SCOPE OF THE PROJECT
The entire project covered the following:-
(i) Reconnaissance (both office planning and field reconnaissance).
(ii) Data acquisition:
(a) Selection of stations.
(b) Traverse angular observation and data recording.
(c) Linear measurement with the aid of Mato NTS352R total station.
(d) Spirit leveling of traverse centre line and adjacent sides (longitudinal or profile and cross sectioning).
(e) Fixing of details by tacheometry method.
(iii)Computations to determine:
(a) Horizontal coordinates (i.e. x and y coordinates)
(b) Vertical coordinates (i.e. z coordinates) by level reduction.
(c) Setting out angles and distance for the curve.
(iii) Data analysis i.e. comparing result obtained with the required accuracy.
(iv) Data presentation :
(a) Production of horizontal alignment (i.e. plan showing existing features and the propose route).
(b) Production of longitudinal section plan
(c) Production of cross section plan
(d)Project report writing: - This involves writing of detail report in connection with entire project done in conformity with the outline given by the project supervisor.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTTheproject was focused on the execution of route surveying for the purpose of road reconstruction from Oriawo along Ogbomosho road, Oyo to School of Science, Sabo Oyo Town. Stations were selected along the existing route at regular intervals as in the specificationsTheodolite traverse was run over stations, while levels were observed along the longitudinal and cross-sections of the traverse lines. All data were gathered with effective orientation from the controls, these were used to pro ... Continue reading---

CHAPTER TWO - [ Total Page(s): 3 ]Traverse is a sequence of connected straight lines whose direction and distances have been measured. Traverse is also the process of connecting series of lines with known bearings and distances. It is subdivided into first order for precise measurement and second order for the establishment of secondary controls while the third order is meant for survey of tertiary and topographical features.Basak (2000) explained leveling as the art of determining the relative vertical heights of different poin ...

Having carried out the reconnaissance, six (6) second order control stations were located and used as connection along the given route. The total number of nineteen (19) stations excluding the controls where the angles and distances were determine by a closed traverse met ... Continue reading---
