HOW TO CARRY OUT

ROUTE SURVEY FOR

FIBER PROJECT

IMPLEMENTATION

.

WHAT IS FIBER ROUTE

SURVEY

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

WHY IS ROUTE SURVEY

NECCESSARY

At this stage we are discussing the Importance of route survey

to a successful project implementation

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

BEFORE THE ROUTE SURVEY.

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

DURING SURVEYAs 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

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

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.

DISTANCE MEASURING WHEEL

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

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

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

DIGITAL Camera

Digital camera 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 actually carried out. Some of the picture that would be attached to 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 digital camera may not be needed if the GPS has such facility
