What a Consulting Engineer Can Do for You
Because of their broad educational background, consulting
agricultural engineers are a source of information on a wide
variety of topics and can provide help with diverse technical
problems. The design and management services agricultural engineers
provide can be invaluable to small businesses without their own
engineering departments, to agricultural producers and similar
enterprises, and to large businesses or governmental agencies that
want to supplement their in-house engineering departments.
Consultants also can provide service to lending institutions, law
firms, local units of government and planning boards, or to
individuals that need expert witnesses or technical analysis.
What is a Consulting Engineer?
A consulting engineer is an independent contractor retained to
work on a project-by-project basis. A consulting engineer may
work alone or as a member of a consulting firm. Consulting
engineers can provide a high level of technical expertise, direct
personal service, and highly technical advice. Practicing
consulting engineers must be licensed professional engineers in
their state of residence and must qualify to obtain licensure in
other states where they practice or provide services.
What Expertise Does a Consulting Agricultural Engineer
Have?
Agricultural engineers have a diverse educational background that
makes them knowledgeable about many subjects; additionally, they
usually focus their expertise on one of the following areas:
- Aquaculture.
- Biological Applications.
- Energy.
- Environmental Quality.
- Food and Food Processing.
- Forestry.
- Information and Electrical Technologies.
- Power and Machinery.
- Safety.
- Soil and Water Resources.
- Structures and Environment.
Aquaculture
Agricultural engineers assist in increasing production of aquatic
animals, such as fish and shellfish to sell as food and for other
uses, while decreasing costs and environmental impacts. Engineers
with a background in aquaculture seek ways to improve pond and
indoor fish rearing systems, reduce pollution from aquaculture
discharges, and reduce excess water use.
As consulting engineers, they may advise others on the
harvesting, sorting, and processing of aquatic plants or animals
and are often asked to work with today's popular species such as
catfish, oysters, mussels, salmon, trout, carp, shrimp, and prawns.
These engineers also are involved in working with ornamental and
bait fish.
Biological Applications
Agricultural engineers work on issues dealing with cells in tissue
culture, plant systems, humans, animals, or groups of animals.
These engineers also work on design projects with biomaterials,
biomechanics, biological systems modeling, implant design, and mass
transfer in bioenvironments. Needs in medicine, biomedical
engineering, environmental engineering, natural resources,
agriculture, and related areas are met by these
engineers.
Consulting agricultural engineers with extensive biological
backgrounds work to design treatment facilities for human and
animal wastes, to assess water quality, and to develop remediation
plans. State and local departments seek advice from these engineers
on issues of environmental quality. As consultants, these engineers
work with food and pharmaceu-tical companies developing value-added
processes. The engineers may work in biomechanical design
developing prosthetics for humans and animals.
Energy
Agricultural engineers work with systems involving all forms of
energy, including electricity, gasoline, diesel fuel, hot water,
and hot air. These engineers design systems to efficiently pump
water, heat homes, and power agricultural equipment. They study and
test energy options that help maintain modern conveniences while
reducing costs and the adverse effects on the environment.
Consulting agricultural engineers work to find uses for
renewable energy sources such as plants, methane, vegetable oil,
wind, and solar power. These engineers often advise federal, state
and local departments working with potential air contaminants that
result from producing or using energy, and they work on projects to
minimize the waste products that cause air and water pollution.
Environmental Quality
Agricultural engineers are well trained and qualified to
understand the biological and physical treatment of wastewater and
other sources of pollution. With environmental quality having an
ever-expanding role in society, these engineers are often called on
to act as consultants to industry, government, regulatory agencies,
and private citizens.
Consulting agricultural engineers help producers solve problems
with livestock production systems that could have a negative impact
on water and air quality. Many times these consultants assist state
and local governments to develop guidelines to protect water and
air quality. Consultants involved with environ-mental quality
issues can work with problems related to seafood and other food
processing plants that are being required to reduce emission
levels.
Food and Food Processing
Agricultural engineers combine design expertise with economical
methods of large-scale manufacturing to meet industrial needs.
Agricultural engineers serve as experts in food pasteurization,
sterilization, freezing, dehydration, packaging, transportation,
and storage. They also develop designs of microbiological processes
to produce fermented foods, fuels, biochemicals and pharmaceuticals
and to treat municipal, industrial, and agricultural wastes.
As consultants, agricultural engineers work with federal, state,
and local government agencies in addition to pharmaceutical and
health-care firms. Many manufacturers utilize agricultural
engineers with food and process backgrounds to design food and drug
processing equipment and layout processing plants. As
consultants, these engineers design food machinery instru-mentation
that controls the packaging of ingredients and food materials.
Forestry
Agricultural engineers apply physical, biological, and engineering
sciences to solve problems related to the development of forest
production systems. Tasks include designing and manufacturing
equipment for forest access systems; studying machine/soil
interaction and erosion control; and analyzing and improving forest
operations. Agricultural engineers also are involved in decision
modeling and in designing and manufacturing wood products.
Consulting engineers help companies develop detailed harvesting
plans. Work includes finding solutions to complex operations in
timber harvesting, site preparation, and road and bridge
con-struction while conducting operations in an environmentally
acceptable manner. State and local governments also seek advice
from forestry engineers on the management of forest lands.
Information and Electrical Technologies
Agricultural engineers integrate computers, sensors, and controls
with mechanical systems such as automated and robotic systems.
These engineers work with the use of electrical systems and
controls for the farmstead, dairy, and related areas. Not only do
these engineers design complex electronics and electrical systems,
but they must also design these systems to withstand wide
temperature swings, and wet, dusty, and corrosive environments.
Increasingly, manufacturers are asking these engineers to
develop sensors and other electronics to utilize global positioning
technology in site specific or precision farming systems. These
consultants have been retained to develop visual sensing equipment
that evaluates fruit and vegetable quality. Producers also retain
consultants to evaluate problems with stray voltage in animal
confinement areas.
Power and Machinery
Agricultural engineers design and test the tractors and tillage
systems, the planters and sprayers, and the combines necessary for
the production of traditional agricultural products such as corn,
soybeans, and small grain. These engineers also are responsible for
developing the machines used in the culture, harvest, and handling
of fruits and vegetables and forest and forestry products.
Agricultural engineering consultants often are retained by
medium to large companies involved in the manufacturing of farm and
industrial off-highway equipment. Companies in allied industries
such as turf and landscape equipment manufacturing look to retain
the services of these consultant.
Safety
Agricultural engineers are familiar with safety standards used to
design equipment, and many times are on national committees that
develop new standards. Safety engineers also may join committees to
develop these standards. Equipment manufacturers want to provide
equipment that can be operated and maintained safely and look to
the services provided by agricultural engineers to help meet that
goal.
As consultants, agricultural engineers may be used to evaluate
the safety of machinery before it is manufactured. They also are
employed to check worker safety in manufacturing plants,
construction companies, and other industries. Government agencies
often seek assistance from consulting engineers when evaluating
issues related to safety and safety compliance.
Soil and Water Resources
Agricultural engineers are experts in agricultural hydrology and
hydraulic principles pertaining to drainage, erosion control, and
irrigation. These engineers are watershed management specialists
who understand the interactions that occur between human and
natural processes needed to manage watersheds. These engineers also
work with crop water requirements, seek ways to control soil
erosion, and study the environmental effects of sediment on water
quality.
As consultants, agricultural engineers design, build, operate,
and maintain drainage and irrigation systems, water control
structures for reservoirs, floodways, and channels. They monitor
drainage and irrigation water quality, and they design equipment
for applying fertilizers and pesticides through irrigation
systems.
Structures and Environment
Agricultural engineers have extensive knowledge in the analysis
and design of construction projects and in the use of construction
materials. They have technical knowledge in the design of
light-framed steel structures, wood structures, concrete
structures, and grain bins. They are specialists in grain aeration
systems, indoor air quality in livestock facilities, farmstead
layouts, animal flow, and manure management.
Livestock producers often retain consulting engineers to develop
farmstead layouts for animal production facilities, including
siting buildings and manure storages, and developing manure
management plans. Federal, state, and local governments seek advice
from these consultants when developing regulations that can affect
livestock operations. These consultants design facilities for
commercial greenhouses. Agricultural engineers are retained to
develop animal laboratories or specialized plant growth chambers.
Consultants in this area also assist large and medium companies in
the design of grain elevators, feed mills, and foodprocessing
plants.
When Should a Consulting Engineer Be
Considered?
As consultants, agricultural engineers frequently provide services
in building construction. They often serve as expert witnesses in
legal cases involving building failure, livestock housing, or
manure management. They work as accident investigators, and they
frequently provide advice for designing and evaluating new
products. Consider retaining a consulting engineer for a
construction project when dealing with complex designs or needing
technical assistance with permitting issues. You also may want to
retain a consultant in any instance that deserves an unbiased
technical analysis or a reliable, high-quality second opinion.
Construction Services
Services typically provided by consulting engineers involve
preliminary investigations, feasibility studies, cost comparison of
alternatives, design, bid letting, contract negotiation, and
construction monitoring and inspection. Most often, the best
facility planning teams consist of professional engineers, who are
familiar with, but impartial to, design and construction
techniques, and the eventual operator, who is familiar with the
particular needs and performance requirements of the operation.
Once the planning team has been established, the professional
engineer leads the planning team through the design procedure.
Expert Witness
As expert witnesses, consulting engineers provide preliminary
investigation, technical investigation, consultation, and
testimony. In the role of expert witness, the consulting
engineer serves as an unbiased professional who provides testimony
based upon technical expertise. The academic preparation of
agricultural engineers qualifies them to deal with a broad spectrum
of case types.
Accident Investigation
In situations involving personal injury or property damage, the
consulting engineer often can be an invaluable resource. Often
there are no eye witnesses, or witnesses are confused as to what
happened. An engineer often can do the best job of reconstructing
an incident. The engineer knows what is physically possible and can
make the appropriate calculations. Engineering intuition and
imagination help to develop reasonable reconstructions.
Engineering training is invaluable in the technical analysis of
assumed possibilities. Engineers also have the advantage of working
with materials and knowing how materials react.
Product Development or Evaluation
Many companies retain consulting engineers to provide specific,
short-term expertise. Often a company may choose to retain a
consulting engineer to ease the work load on regular permanent
staff, thereby procuringnicheexpertise that is not resident or is
not required on a regular basis. In so doing, companies often
secure the services of a uniquely qualified individual (as opposed
to simply excellent technical competence) for a specific
project. The consultant provides fresh ideas or concepts,
often from alternative disciplines, and contributes unbiased
evaluations of the projects or designs under
consideration.
Consulting opportunities available to power and machinery
engineers are a good example of this trend. To keep up with the
growing demand for innovative, high-tech equipment, farm equipment
manufacturers need more engineers than are graduating from
universities. As a result, many smaller companies and some of the
larger ones retain consultants for new product design. Power
and machinery consultants design agricultural or industrial
equipment and make the initial tests on it before turning it over
to the company for manufacturing. Consultants are involved in
projects ranging from small lawn and garden machines to giant
mining and earth moving equipment.
What Should You Look For When Considering a Consulting
Engineer?
Just like any major decision in which the outcome has a long
standing effect, a little investigation is important. When looking
for a consulting engineer, consider the engineer's qualifications,
experience, and availability. Important steps are to check the
engineer's educational background and to ask for a list of previous
clients and projects. Another important factor is to determine the
availability of the engineer. Engineers with many on-going projects
may have difficulty in meeting deadlines and may have trouble
completing projects on time. Check to see if the engineer is
licensed. Typically, engineers will advertise that they are
licensed on their business card with the letters ieP.E.l. A
consulting engineer who is licensed has met the approval of a state
or U.S. territory licensing board. This ensures a certain level of
competence and expertise. In addition, hiring a licensed engineer
has other distinct advantages. Only a licensed engineer may
prepare, sign, seal, and submit engineering plans and drawings to a
public authority for approval. Also, because of the licensing
procedure, a licensed engineer is often considered a more credible
expert witness or accident investigator than his or her unlicensed
colleague.
