Foreword
I am pleased to present a foreword to this book, aimed at explaining surveying methods and
practices to Civil and Mining Engineers. The authors have made a sharp distinction between
engineering surveying, a profession in its own right, and the surveying knowledge require-
ments expected of Civil and Mining Engineers. The book is the result of close cooperation
between the Departments of Civil Engineering, Mining Engineering, and Spatial Sciences at
Curtin University and the University of Western Australia; the course has been presented to
undergraduate and postgraduate students over a ten-year period.
Throughtheoryandpractice,usinglecturematerial,workshopsandpracticalexercises,the
half-semester course provides the Civil and Mining Engineer with an understanding of sur-
veying,enablinganinformeddiscussionwithsurveyors.Additionallythecoursepromotesand
examines practical skills that will enable a Civil or Mining Engineer to perform simple,
inexpensive, survey tasks that should be part of an engineer’s skill set. The survey ability is
also expected by many Civil and Mining Engineering associations, and the course can be
proffered by tertiary institutes as an example to professional accreditation bodies.
As Mine Managers, graduate Mining Engineers have a particular responsibility for all
surveying on a mine site. This book aims at giving them the ability to examine survey
planning and to understand the presented survey result, again through general theoretical
knowledge and targeted practical workshops and exercises.
Theory moves from basic plane surveying to geodetic surveying principals, and includes

confidence.

of the book is based on a number of years of experience gained in presenting the course at
undergraduate and postgraduate levels. The course is designed to guide engineers through
surveyingtasksthattheengineeringindustryfeelsisnecessaryforstudentstohaveinorderto

many excellent textbooks available on the subject of civil engineering surveying, but they

been gathered into this book to show what techniques lie behind a surveyor’s repertoire of

The Civil Engineer. A role in ambitious construction projects
http://courses.curtin.edu.au/course_overview/undergraduate/civil-engineering
Civil engineers design and construct infrastructure such as:
(cid:129) bridges
(cid:129) roads
(cid:129) harbours
(cid:129) highways
(cid:129) dams
(cid:129) buildings.
Asabuiltenvironmentbecomesincreasinglycomplicated,ambitiousconstructionprojects
are completed by teams of people with different skills, working together. The civil engineer
plays an important role in this process.
The Mining Engineer. A stepping stone to Mine Management
http://courses.curtin.edu.au/course_overview/undergraduate/mining-engineering
Mining engineers plan and direct the engineering aspects of extracting mineral resources
from the earth.
Mining engineers plan and manage operations to exploit minerals from underground or
open-pit mines, safely and efficiently. They design and direct mining operations and infra-
structure including:
(cid:129) drilling
(cid:129) blasting

(cid:129) loading and hauling
(cid:129) tunnel creation and maintenance
(cid:129) access road planning and maintenance
(cid:129) water and power supplies.
Mining engineers may supervise other engineers, surveyors, geologists, scientists and
technicians working on a mine site and may find employment in metropolitan or regional
locations or in different countries.
The tasks with which a mining engineer may be associated include:

ciency, safety and environmental conditions
(cid:129) talk to geologists and other engineers about the design, selection and provision of

(cid:129) coordinate with the operations supervisor to make sure there is proper implementation
of the plans
(cid:129) operatecomputerstoassistwithcalculations,prepareestimatesonthecostoftheoperation
and control expenditure when mines begin production
(cid:129) oversee the construction of the mine and the installation of the plant machinery and

(cid:129) make sure that mining regulations are observed, including the proper use and care of
explosives, and the correct ventilation to allow the removal of dust and gases
(cid:129) conduct research aimed at improving efficiency and safety in mines
(cid:129) establish first aid and emergency services facilities at the mines.
In broader terms a qualification in engineering is a prerequisite to an advancement in
engineering management. For mining engineers in Western Australia it is a statutory
requirement proscribed by Act and regulation (the Mining Act). For civil engineers
advancement in management depends on demonstrated competencies in a number of fields;
investigation, design, analysis, costing, quantity surveying, tender documentation and pre-
sentation, project coordination and management, project delivery, safety and human resource
management.
Essentially, engineering is about management of the project and the resulting built envir-
onment,abouttheintegrationofdiversegroupsofskilledprofessionalstoachieveacommon
goal.
Then, “Why Surveying?”
Youwillhaveateamofsurveyorsintimatelyinvolvedincontrollingtheplacementofyour
design. They ensure not only adherence to the design dimensions, but also, through licences
surveyors, ensure the legal location of the project in terms of cadastral boundaries.
Encroachment on another property is an expensive business.
So, “Why Me? Won’t the Surveyor do it?”
