HOW TO CARRY OUT ROUTE SURVEY FOR FIBER PROJECT IMPLEMENTATION

  1. 1. HOW TO CARRY OUT ROUTE SURVEY FOR FIBER PROJECT IMPLEMENTATION .
  2. 2. WHAT IS FIBER ROUTE SURVEY
  3. 3. This stage of fiber project implementation is very crucial to the success of the project to the client and the contractor. It involves moving round the proposed fiber cable route for ground truthing/verification exercise. The process involves the use of certain hardware devices and software. The hardware (GPS and Distance measuring wheel in this case) are used to capture the points and line features on the project proposed route while the software are deployed to edit, manipulate and collate the captured data for further analysis
  4. 4. WHY IS ROUTE SURVEY NECCESSARY At this stage we are discussing the Importance of route survey to a successful project implementation
  5. 5.  To present some level of Accuracy  To generate Project drawing (proposed route drawing showing the location of the surveyed facilities)  For Financial proposal (generate BoQ : Bill of quantity)  Information about Manhole coordinates  Information about Manhole to manhole cumulative distance  Information about Terrain details and quantities  To serve as Implementation guide
  6. 6. BEFORE THE ROUTE SURVEY .
  7. 7. The scope of work(sow) document already rolled out to the prospective contractors to study and know the scope of the work which include the starting point and the ending points, the sites to be connected (names, locations and their coordinate), the proposed route for the cable. Most of the information on the SOW are sketchy and merely to guide the survey team, they are not 100% accurate, hence, the need for technical site survey. The SOW given on a hard copy will have the image/picture of the proposed route displayed on a plain sheet or Google earth cut-out
  8. 8. DURING SURVEY As said earlier the survey process is a ground trothing exercise that requires some levels of details and accuracy for easy implementation. In a rough terrain, it might require moving on foot with the capturing equipment and camera. Taking note of all the different terrain, marking of manhole location, and noting various obstacles and proffering way-out
  9. 9. ROUTE SURVEY EQUIPMENT • GPs Device • DISTANCE MEASURING WHEEL • DRAWING MATERIALS (PAPER, PENCIL) • DIGITAL Camera
  10. 10. ROUTE SURVEY EQUIPMENT • GPs Device • DISTANCE MEASURING WHEEL • DRAWING MATERIALS (PAPER, PENCIL) • DIGITAL Camera
  11. 11. GPs Device GPS known as Global Position system device is tracking and data collection device that have been programmed to work with minimum of 4 satellites at every point in time. It can capture both line and point data. X and Y coordinates for point data and series of X and Y coordinates for line data Point features such as Manhole locations, cell site location, other major landmarks on the route are recorded as waypoints. Line or linear feature such roads/street, terrain on the route are represented with lines are called tracks and Routes
  12. 12. GPs Device POINT FEATURE COORDINATE (XY) Latitude N6 26.948, Longitude E3 28.668 LINE or LINEAR FEATURE (XY,XY+1, XY+2………..XY+n) The GPS also has the capacity to record the timing of record and the Z-value (the elevation) of each feature captured All the captured details are store in the GPS which is downloadable into computers system that has compatible software for further analysis. GPS is battery powered, hence it can be used in a remote area without fair of malfunctioning.
  13. 13. DISTANCE MEASURING WHEEL
  14. 14. The measuring wheel takes the record of distance as the tyre of the wheel revolve progressively. This equipment is suitable in capturing the terrain data.it is connected with the satellite nor uses battery. It is purely manual in operation. It doesn’t store data intelligently as GPS. Someone needs to be writing down the value on a data sheet feature by feature. It is only useful to measure line/linear feature. With good GPS in place during survey, a measuring wheel is not very necessary
  15. 15. DRAWING MATERIALS (PAPER, PENCIL) A jotting material is required to compliment the work of the Gps for more accuracy to be sure and more details to be captured without wasting time. While GPS capture the features and give annotation, sketch drawing of the surveyed portions will be taken
  16. 16. DRAWING MATERIALS (PAPER, PENCIL) A jotting material is required to compliment the work of the Gps for more accuracy to be sure and more details to be captured without wasting time. While GPS capture the features and give annotation, sketch drawing of the surveyed portions will be taken
  17. 17. DRAWING MATERIALS (PAPER, PENCIL) • The information on the sketch drawing include • The names of the roads traversed • Manhole numbering • Major landmarks on the road • The values of the measured featured • Side of the road surveyed
  18. 18. DIGITAL Camera Digitalcamera is needed to capture what is referred to as project picture. This is to some extent to prove to the client that field survey of the proposed route were actuallycarried out. Some of the picture that would be attachedto the drawing include: picture of obstruction, thrust boring, diversion,bridge crossing, bad terrain (swamp, erosion prone areas, road shoulder encroachment etc). most of the time digitalcamera may not be needed if the GPS has such facility
