Definition of Route Surveying
Route Surveying is a branch of Civil Engineering dealing with the design and
construction of linear works, such as roads, highways and pipelines. 1A ocation Control !Route
Survey" refers to surveys e#ecuted for the purpose of ac$uiring an interest along a linear
corridor. %A co&pleted route survey will provide sufficient $ualitative infor&ation and
di&ensional data for indicating the feasible align&ent, grades, and cross sections, and proposed
right'of'way lines. A route does not provide construction data as can be developed fro& a
preli&inary survey. Rather, a route survey provides infor&ation and data pertaining to general
location possibilities, feasibility, and probable cost of right'of'way, construction, use, and
&aintenance. ()ighway surveys involve &easuring and co&puting hori*ontal and vertical
angles, elevations, and hori*ontal distances. +he results of these surveys are used to prepare
detailed plan and profile base &aps of proposed roadways. n addition, the elevations deter&ined
in the survey serve as the basis for calculation of construction cut and fill $uantities, and in
deter&ining roadway banking. +his section presents a review of basic ter&inology, concepts, and
standard procedures used in highway surveys. Surveyors are tasked with finding the &ost
effective route to follow. An engineer will use the data gathered by the Surveying party or tea&s
to plan out the route pro-ect in detailed work with certain specifications for workers to follow.
+ea&s &ay spend days or weeks in the work field, varying on the nature of the pro-ect and where
it is built. t is necessary to have a surveying degree or si&ilar $ualification to participate in a

urpose of Route Surveying
Route surveying is to plan, design, and laying out of route such as highways, railways,
canals, pipelines, and other linear pro-ects. t co&&only updates topographical, geological, soil
and other &aps. Route Surveying is a /survey of the earth0s surface along a specific or particular
route and it correlates selected contours and ob-ects with geodetic reference points and
land&arks during linear surveys and also in the study of the dyna&ics of natural and
socioecono&ic pheno&ena in a narrow strip of terrain. n a route survey, representations of the
actual course of the survey and of the plane hori*ontal features on both sides of a specific road is
within the li&its of direct possibility are plotted on a &ap board using ðods of instru&ent
surveying. +his type of Surveying has been e#tensively and widely used for centuries in &apping
inaccessible areas. Route Surveying is done for such principally as sets of survey -obs to
supple&ent a co&prehensive survey. Route surveying works &ay include surveys of e#isting
roadways for upgrade or locating proposed new transportation syste&s. Route surveys re$uire,
by their nature, the use of curves to ease the transition for vehicular &ove&ent along these roads
and to increase the safety for the driving public

ntroduction of Route Surveying
A faculty of Applied Engineering and 2rban lanning Civil Engineering Depart&ent
known as the 2niversity of alestine introduced Route Surveying as a 3survey that deals with the
route or course that a highway, road, or utility line will follow. Centre line layout is one of the
first steps in constructing a road. +he certain road is broken into stations, in which in each
station, the location of the center'line shoulder and slope stakes are identified. Route surveying
pertains to the laying out of proposed corridors for transportation syste&s. Road surveying is an e#tensive
study of a specific entire area that &ight be used for a road or airfield. ts purpose is to eli&inate or add
routes or sites which are i&practical or unfeasible and to identify the &ore pro&ising routes or
sites. Route Surveying along a co¶tively narrow strip of territory for the location, design
and construction of any route of transportation, such as highways and railroads, canals and
flu&es, pipeline for water, sewage, oil and gas, cableways

&portant Structures for Route Surveying
+he surveying party can &ake reco&&endations and suggestions about the route to help
engineers prepare plans. Engineers are people who always &ark in their &inds that the &ost
i&portant concept they should never forget is the safety of the people. +hey &ay think about
issues like whether it would be better to go through or around various aspects of the landscape4 a
deep valley &ay be cheaply traversed with a bridge, while a large &ountain &ight be too big to
tunnel through, necessitating a diversion of the route around it.5
Surveyors &ust acco&plish the &ost direct and efficient route. E#penses can rack up very
$uickly and highly pricy when laying out roads, railways, and utility lines, especially in the face
of obstacles like hills, large rivers, and the like. +hey also need to consider geologic ha*ards like
faults caused by the &ove&ent of the earth0s crust in &uch une#pected ti&es which could
present a threat to the integrity of the finished pro-ect.

6ost of the ti&e, 7various co&panies or govern&ents will hire a surveying party to route
survey as they prepare to e#tend services across a new areal peri&eter. +he surveyors will &eet
with representatives to discuss plans, such as the nu&ber of lanes in a roadway or the type of
utilities being laid across a region. +his infor&ation can be i&portant for planning, as surveyors
need to think about the para&eters of the pro-ect. +he surveyors use a variety of e$uip&ent on
the route survey to profile the landscape, taking special note of geologic for&ations, property
lines, and other features that &ay beco&e an issue.
