Abstracts:
It’s expedient to know that there are several ways of awarding highway contract as discussed in these term paper compiled by me and all information were sourced online and thoroughly scrutinized by comparing facts to facts, events to events, challenges to challenges, solutions other solutions incurred by various clients and contracted companies and personnel and a little delve into the historical methods that birthed the ongoing trends now as well as some future predictions.
All highway contracts are usually and always Government projects and therefore the most adopted method is as that of the selective tendering as it is widely adopted with varying names and application pending on the region to which it is applied.
Highway contracts are usually awarded to known contractors in a particular nation and region as binding to their general applications and known reputation to perform due time stipulation as stated in nitty-gritty of the contracts document. The following terms cannot be undermined when highway contracts are been fostered as methods and factors guiding the clients and contractors;
·         Competitive bidding.
·         Warranties.
·         Quality control.
·         Multi parameters.
·         Reviews of constructabilities.
·         Quality-based Contractor Prequalification.
·         Design build.
·         Future applications; Electronic biddings.
·         Innovations, challenges, solutions incurred and other interventions.
The ever changing world in vast models, software, and materials is making the awarding of highway contracts ever competitive.


Methodology:
The information is as referenced below and were carried out by me; via online researches through internet surfing and compilation to meet suits the topic demands.
Introduction:
There are several methods for awarding contracts for highway project construction. Transportation construction is a large industry—particularly highway construction, on which more than $50 billion is spent annually. Small improvements can result in significant savings in time and cost, as well as better quality and fewer disputes. In recent years, many innovations have occurred in highway construction. The atmosphere within the industry is highly charged with optimism, uncertainty, and debate. Contracting methods for highway construction work are no exception to these developments.
This is the way used during a procurement in order to evaluate the proposals (tender offers) taking part and award the relevant contract. At this stage, eligibility of proposals has been concluded and by so doing choosing the most preferable among the proposed.
Description: C:\Users\Egbetade G.O\Desktop\ff.jpgHighway Construction (Engineering):
This scope covers a wide range of engineering works and scope which includes planning, design, construction, operation and maintenance of roads and tunnels; which ensures safe and effective transportation of people and goods. They consider future traffic flows, design of highway intersections/interchanges, geometric alignment and design, highway pavement materials and design, structural design of pavement thickness, and pavement maintenance. (wikipedia, 2015)
Planning/Development: This involves the estimation of current and future traffic volumes on a road network. They try to predict and analyze its effect and adverse effects on the environment, such as noise pollution, and other ecological impacts.
Financing; most countries are always faced with high maintenance cost of aging transportation highways. Multi-purpose characteristics of highways, economic environment, and the advances in highway pricing technology are constantly changing as well.
Highway construction is usually preceded by detailed surveys and subgrade preparation. The methods and technology for constructing highways has evolved overtime and become increasingly sophisticated and thus has raised the level of skill sets required to manage such construction.  We’re considering factors such as the project’s complexity and nature, the contrasts between new construction and reconstruction, and differences between urban region and rural region projects. Contractors are required to be vast in the below and of admirable success of such or similar works.
·         Materials to be used.
·         Material quality.
·         Installation techniques.
·         Traffic.
·         Environmental aspects.
·         Managerial and maintenance skills.
·         Political aspects.
·         Legal and public concern.
The old method of contracting highway construction: The traditional approach to contracting for highway construction projects has been design–bid–build. Under this approach, projects are awarded to the qualified bidder with the lowest total price, pay items are established on a unit price basis, the specifications for highway projects are strict method specifications, and the role of the owner or agent is to inspect.
By the 1970s, as a result of this approach, the industry had developed into a highly litigious environment of owners, contractors, lawyers, and claims consultants. In the 1980s, as the total quality management movement grew in the United States, transportation agencies started to question whether these traditional contracting methods were really cost effective and quality oriented. As a result, many research projects addressing highway construction were initiated. The traditional lowest-responsive-bidder system is well-understood and accepted throughout the country. Most contractors are comfortable with the procedure and understand its risks and rewards.
The approach is also generally considered to be fair. However, it does have some limitations. The system is slow and does not favor a life-cycle cost approach to projects. Innovation is often stifled; some innovative ideas necessitate changes in laws and regulations and are therefore difficult to implement. In addition, there is little opportunity for contractor input into design, and quality is often an issue of dispute. Moreover, the traditional system requires that the highway department have a large staff to conduct all of its necessary functions.


Current Highway Construction Practices:
Description: C:\Users\Egbetade G.O\Desktop\dek.jpgThe highway sector is perhaps the most conservative segment of the construction industry. Although highway contractors have implemented many new construction technologies, owner contracting methods have until recently remained the same.
Rejuvenating practices of awarding contracts:
Awarding Contracts ways:
The method by which contracts are awarded is ordinarily regulated by statute or constitutional provision, and the prescribed method must be followed. For significant expenditures of public funds, government bodies usually must use a bidding process. In the awarding or letting of public contracts such as a highway project, the public body invites bids or makes "requests for proposals" so that it can award the contract to the bidder who qualifies under the terms of the governing statute. The submission of a bid in response to an invitation is considered an offer, and although it may not be freely withdrawn prior to acceptance, it does not become a contract unless and until such time as it is accepted by the proper public authority. A bid that does not respond to the terms contained in the invitation to bid is not within statutory requirements but is considered to be a new proposition or a counterproposal.

Warranties: A warranty is an assurance that a product will serve its useful life and that if it does not, the provider will replace the product or pay to return it to its proper condition. The current warranty for almost all government-funded projects is the performance bond. This bond provides assurance that the materials and workmanship of the contractor will be good during the project and up to 1 year after project completion and acceptance. The use of long-term warranties is a common practice in Europe and other countries. The governments of both Europe and America believe warranties motivate the contractor to do a better job than would be done without such assurance. Warranties have a perceived higher initial cost and in practice some believe the cost of a warranted contract is comparable to that of a no warranted contract. The warranty approach has, however, met with stiff resistance from contractors, surety companies, and contracting agencies in countries like United States. Many contractor organizations are opposed to warranties because small firms may not be able to obtain bonding to cover Construction Management 3 warranty projects, and may therefore be denied the ability to bid on such projects. Large contractors, on the other hand, could see a reduced volume of contracts. Surety companies are skeptical, but have backed some contractors bidding on highway work that requires long-term warranties. Most of the work warranted to date has involved asphalt paving, pavement striping, and bridge painting. (HANCHER)
Quality Control Transfer: The transfer of quality control has for some time been a major requirement on highway construction projects and the subject of many problems for highway agencies. With increasing costs and shrinking staff resources, many agencies are addressing these problems by specifying that contractors are responsible for quality control, with only performing quality assurance tests to ensure that the contractor is fulfilling its quality control responsibilities properly.
This approach allows the government agency to reduce its staff, which in turn results in lower operating costs and, therefore, lower overhead costs. The contractor can reduce project costs by having more control over materials and workmanship, but this cost savings is lowered somewhat by the need to hire more people to handle the quality control activities. To ensure that a project meets those standards, government representatives spot-check some parts of the project for quality assurance. The contractor is penalized if the project is not meeting its requirements. Penalties can include being removed from the contract if the project is of very poor quality. Contractors are also required to submit and have approved a plan for carrying out the quality control function.
Description: C:\Users\Egbetade G.O\Desktop\fr.jpgCompetitive Bidding
For major government expenditures, such as construction highways roads, government bodies require competitive bidding, which is a well-defined public process of letting a contract. Competitive bidding is a means of preventing political graft and corruption because the public nature of the process discourages favoritism and fraud. The integrity of the process is a central goal of competitive bidding. If a public official or employee is later found to have had an interest in a public contract, the agreement is void and unenforceable, and the interested parties may be subject to criminal prosecution. To provide bidders with an opportunity to bid competitively on the same work, the appropriate public authorities must adopt plans and specifications that definitely set the extent and type of the work to be done and the materials to be furnished. The public entity itself must prepare these plans and specifications, and it must provide all prospective bidders with the same specifications from which to prepare their bids. The specifications must not be drafted so as to restrict bidding to a single bidder unless it is clearly essential to the public interest to do so.

Multi-parameter
Bidding Cost plus time (or X + Y) bidding is a contracting procedure that still involves looking at the lowest initial cost, but also factors into the selection process the added cost of time to complete the project. The time cost for bidding is calculated by multiplying the estimated time of the project by a set daily user cost. The bid for award consideration is based on a formula comprising the traditional price bid by the contractor (X) and the amount of time allowed for the project (Y). The award formula is as follows: award bid = (X) + (Y t road user cost/day). This formula is used only to determine the lowest effective bid for award, and not to determine payment to the contractor.
By incorporating a quality element into the bid, the contractor is promising to perform at a set level, or to receive a disincentive for failing to do so.
Reviews of Constructability
Constructability reviews involve a formal process of allowing contractors to provide input on the design of a project. The contractor reviews the design to determine the level of difficulty of construction, and to suggest design revisions that could enhance the construction process while resulting in possible cost and time savings and fewer disputes. Such reviews result in greater potential for a better-quality final product. Constructability review is most effective when contractor input is sought during the preliminary design phase, not just before the bidding process begins. It is much easier to implement changes in philosophy early in the design process, instead of waiting until the design effort is nearly complete. One reason for the failure of value engineering on highway projects was the animosity that occurred among designers when contractors expressed criticism of nearly completed designs. Value engineering input is now sought only for minor changes after a project has been awarded.
Public contribution has been always been successfully, and constructability input has been improving overtime.
Design–Build
Design–build is probably the most discussed and controversial issue in transportation construction today. A popular contracting method in the private sector for many years, it has not seen significant use in the public sector. Under the design–build approach, design and building of a project are performed by a single company or a joint venture of companies. This approach provides the government with one source of responsibility for the project. The design–build group shares information throughout the project, beginning with the design phase. The responsibility for all problems is centralized in the design– build firm. Design–build does face legal barriers in some states where the process is not allowed. Because of federal statutes regarding design and construction contracts, considers such contracts to be experimental.
The most visible example of design–build is the rehabilitation of Interstate 15 in Salt Lake City, Utah. This project involves the complete renovation of 16 Construction Management 5 miles of roadway and 137 bridges in preparation for the 2002 winter Olympics, at an estimated cost of $1.36 billion. Three bidders pursued this historic project, and the two that were not selected received a complimentary stipend to cover their costs for the preliminary bidding. A 10-year maintenance warranty is also included in the bid to ensure that the contractor will complete the project as expected. Attitudes about design–build are beginning to change. A major benefit is reduced time for the total project and better design for complex projects as a result of the designer–builder interaction that occurs from the outset. There is, however, a great deal of resistance from the design community, which fears that cost will dominate decision making and result in lower-quality designs.
Description: C:\Users\Egbetade G.O\Desktop\gh.jpgDescription: C:\Users\Egbetade G.O\Desktop\fr.jpgQuality-based Contractor Prequalification
Prequalification of contractors has been used for years to screen out firms that represent a risk of inot adhering to state highway project specifications. Although many standards are set with which interested contractors must comply for prequalification, essentially all that is required is the ability to secure a bid or performance bond for a project. One of the major qualification criteria is the quality of prior work performed, but this criterion has generally been discussed and not enforced. The emphasis on quality performance, however, is now becoming a major factor in evaluation. The Ontario Ministry of Transportation has begun using a highly innovative approach to contractor prequalification to improve the quality of performance and reduce infractions on its projects. This approach involves evaluating the contractor in four areas: quality, safety, timeliness, and contract execution. Each area is given a different weight in the determination of a contractor’s performance index: quality counts for 60 percent of the contractor’s rating; safety and timeliness each account for 15 percent, and contract execution for the remaining 10 percent. The performance index covers the past 3 years and is weighted to give the most recent projects more influence. Contractors are allowed to appeal and attempt to improve their rating.
The performance index is used to either increase or decrease the amount of work a contractor can be Description: C:\Users\Egbetade G.O\Desktop\tru.jpggiven on the basis of the prequalification limit.
Note: DOT- Department of Transportation.

Electronic Bidding
Most contractor bids are prepared and updated using laptop computers and spreadsheets, but a paper copy must still be submitted to the DOT at a set time. This requirement can cause a hardship for contractors who live at a great distance from the DOT’s main office and for those that receive subcontractor prices at the last minute. Moreover, the rushed nature of the process results in a greater chance of errors. Allowing electronic bidding can alleviate these problems. Electronic bidding is not limited to accepting bids from contractors. Announcement of the invitation to bid and the bidding documents, along with the relevant plans and specifications, can be placed on a DOT’s website for the review of interested contractors. Contractors can send their bids either by submitting a disk, by using electronic mail, or by uploading the bid to the DOT website. The DOT can also list the bid reports on its website. Transportation in the Millennium 6 The use of electronic bidding should benefit both contractors and DOTs. The major concern with electronic bidding, however, is security. How can the DOT and contractors be certain that the files they send or receive have not been tampered with and have been sent by the correct person? Software exists for ensuring the privacy of transmission on the Internet; however, DOTs have not yet developed such in-house systems for handling full electronic bidding processes. (HANCHER)
Description: C:\Users\Egbetade G.O\Desktop\images.jpgWinning Contracts and evaluating tenders is essential to the continuing viability of any contractor / client. It involves an understanding of the issues and requirements of the procurement stage but also the skills and ability to structure the tender not just to be successful but to increase profits as well.
The department offers work through a tender process and various construction and maintenance contract arrangements. In general, tenders will only be considered for Transport and Main Roads' major works using the road construction contract (RCC) document if the tenderer is currently prequalified. The prequalification level of the tenderer must be equal to or greater than the advertised project level for the works. Tenders Transport and Main Roads generally calls for tenders for its construction projects. A number of projects, however, are delivered under sole invitee arrangements with local governments or with. Transport and Main Roads' own commercial units.
Challenges of the Future Innovations in Highway Contracting
They are just beginning to be implemented. After years of stagnation, many innovations are now being implemented in several states, while many others are under review for possible implementation. in addition to innovative contracting construction management 7 practices, there will continue to be a demand for enhanced technologies, such as construction equipment automation, new construction materials, improved design methods, and improved construction operations.
There will be much support for further study and evaluation of these innovative practices and technologies, and many will result in formal research projects conducted by dots, consultants, and university researchers.

Conclusion
It is clearly expressed that there are various forms to which a tenderers would be awarded a highway construction project by the clients and with several intrepid personnel that help cut down excesses and companies overheads to which the contracts are awarded.
Recommendation
Research ought to be carried out in various countries by contractors on how they can maximize the natural resources available, rather than employ and import their materials and contractors from other countries by so doing beating cost. If more indigenous contractors were trained by their government by sending to other countries and contractors that has successfully undergone such projects, then the cost incurred by awarding the contracts to foreign contractors would be reduced, providing more jobs to indigenous contracting firms. I.e. Most Nigeria’s contracts for highway and roads generally are awarded to foreign companies such as Julius Berger, RCC etc. Information says the country still owes companies as Berger which could be curtailed if locals were trained and undertake such projects to cut down this big companies costs and overhead of importing and running the operations.

Dangote now 23rd richest in the world

NIGERIAN business mogul, Alhaji Aliko Dangote, has retained his
position as Africa’s richest man with a $25 billion net worth.
He has held that position for the fourth successive year.
Globally, the influential Forbes Magazine rates him on the list of 25
richest people in the world.
Dangote is ranked 23 up 43rd among the 100 richest persons in the
world.
The Nigerian businessman with interests in cement, sugar, beverages
and petrochemical is said to be presently the first black man to break
into the rank of top 25 richest people in the world.
Mike Adenuga, owner of indigenous telecoms company Globacom, was
next to Dangote on the list with a wealth of $4.6 billion, maintaining
325 position in the world, while Folorunsho Alakija, with $2.5
billion, was 687 in the world and Abdulsamad Rabiu ranks 1372 in
the world, with $1.2 billion.
Meanwhile, Bill Gates is back on top after a four-year hiatus,
reclaiming the title of world’s richest person from telecoms mogul,
Carlos Slim Helu of Mexico, who ranked number one for the past
four years.
Spanish clothing retailer, Amancio Ortega (best known for the Zara
fashion chain) retains the number three spot for the second year in a
row, extending his lead over Warren Buffett, who is again number
four.

Why are so many young French people turning to jihad?

The scrapbook is filled with photographs and tributes: they
show Dominique Bons' son Nicolas growing from a teenager into a
young man.
Offering brief glimpses of past holidays and family moments, clues to
his passions and personality, the book is one of Bons' few souvenirs of
her son's short life.
Nicolas, from Toulouse, converted to Islam four years ago, gradually
becoming more and more devout.
Bons, who is a former French soldier, says Nicolas had never spoken
to her about wanting to join a religious war, but last year the 30-year-
old announced he and his half-brother were going on vacation together.
Three weeks later he called to say they were in Syria -- two of the
more than 900 French citizens the government believes are involved in
the jihad there and in Iraq.
Within days, his half-brother was killed, and shortly
afterward he spoke to his mother for the last time,
telling her she would be notified if anything happened
to him.
In late December, Bons received a text message
explaining that Nicolas has been killed in "an
explosives operation" -- that's all she knows.
"The body? There is no body... I don't have a body,"
she says. "If he was killed in a truck filled with
explosives, the body... boom!"
Because no body has been recovered, there is also no
death certificate, meaning that --officially at least, in
France -- Nicolas is still alive.
For his mother, he always will be. In her grief, she
has written a poem -- added to the treasured
scrapbook -- telling her son: "You will exist in my
heart eternally. I love you."
Unlike Bons, one anonymous French bus driver knows
his daughter is still alive in Syria -- but he is
desperately worried that may not be the case for much
longer.
The man -- who asked not to be identified out of
concern for his daughter's safety -- says the 23-
year-old converted to Islam and married a Tunisian
man before moving to Syria with the couple's two
children.
The couple said they were going there to do
humanitarian work; they are now believed to be in Raqqa, and safe --
for the moment at least -- but the city, an ISIS stronghold, is a target
of coalition forces.
And both father and daughter fear she could be arrested if she comes
back to France.
He has a warning for other parents: "Pay attention... it could happen to
you before you even know it."
David Thomson, author of "The French Jihadists," believes there are
many reasons why so many French Muslims are becoming radicalized
and heading to Iraq and Syria to join militant groups.
"Religious frustrations, material frustrations, perhaps a feeling that it
would be a sin to stay back in France, a desire to experience this
historic moment and die fighting the coalition," he explains.
Concerned at the growing threat of radicalization, French authorities
have introduced new regulations in an effort to stem the tide of citizens
traveling to the Middle East to join the fight.
"We had to change our rules in different ways,"
Foreign Minister Laurent Fabius explained to CNN's
Christiane Amanpour recently.
"First we decided that the government, the
administration, would be able to suspend not only
passports but also ID for people whose intention is to
go to Syria."
The second step is to encourage families concerned at
the path their children appear to be taking to contact
the authorities and report their fears.
"Because we have many cases where families do not
agree with the youngster and at the moment they are
aware that the young people want to leave and therefore
they have to get in touch with us in order to have a
reaction," he said.
"We have to be very, very strict and to explain to these
young people, especially the young girls -- 13, 14
years old -- that if they are going there, some of them
think that it will be a new life, [but] in fact they are
prostitutes, they are sexual slaves.
"The young people are utilized and many of them are
killed."
Fouad El Bathy has spent the past nine months trying
to bring his teenage sister safely home from Syria
before it is too late.
Nora, 16, was recruited and given a plane ticket to join
the fight in Syria, according to French intelligence.
Fouad is convinced she is being held against her will, and took the
risky step of trying to find her and get her back -- he was even taken
captive at one point.
But when he finally tracked her down, he couldn't convince her to leave.
"I told her to come back with me but she cried and beat her head
against the wall and she said I can't I can't."
Later he was told the leader of the group wanted to marry her.
Since Nora is a minor, El Bathy's lawyer hopes that if she does make
it back he can persuade French officials to treat her as a victim not a
combatant.
Like El Bathy and Bons, the relatives of many of those caught up in the
jihadists' web say they feel powerless to protect their children and
siblings.

WWF: World has lost more than half its wildlife in 40 years

The world's animal population has halved in
40 years as humans put unsustainable demands on Earth, a new report
warns.
The World Wide Fund for Nature's Living Planet Index, released
Tuesday, revealed the dramatic decline in animal species, and said the
trend could cost the world billions in economic losses.
Humans need one and a half Earths to sustain their current demands, it
said.
The index, which draws on research around WWF's
database of 3,000 animal species, is released every
two years. This year's has the starkest warning yet of
the risks associated with the decline of wildlife.
The fund notes that it's relying on a never-before-used
methodology in this year's report, "which aims to be
more representative of global biodiversity."
The index showed shows a 52% decline in wildlife
between 1970 and 2010, far more than earlier
estimates of 30%. It is due to people killing too many
animals for food and destroying their habitats.
"We are eating into our natural capital, making it more
difficult to sustain the needs of future generations," the
report said.
Researchers from the Zoological Society of London
looked at changes in populations of more than 3,000
species of mammals, birds, reptiles, amphibians and
fish, tracking over 10,000 different populations.
Photos: Spectacular wildlife around the world
The decline in animals living in rivers, lakes and
wetlands is the worst -- 76% of freshwater wildlife
disappeared in just 40 years. Marine species and
animals living on land suffered 39% decline in their
populations.
Animals living in tropics are the worst hit by what
WWF calls "the biggest recorded threats to our
planet's wildlife" as 63% of wildlife living in tropics
has vanished. Central and South America shows the
most dramatic regional decline, with a fall of 83%.
And while the animals are suffering now, the long-term
impact will be on people, the report said.
Marco Lambertini, director general of WWF
International, said "protecting nature is not a luxury....it
is quite the opposite. For many of the world's poorest
people, it is a lifeline."
According to Lambertini, the threat to oceans could
create economic losses of up to $428 billion by 2050.
The global fishing sector employs more than 660
million people, and fish provide more than 15% of
protein in people's diet.
Global food security is under threat as the demands of
growing population drain the resources. Forests
provide water, fuel and food for more than billion people, including
350 million of the world's poorest people.

11 of the world's most amazing train stations

Whether they're blasting over the tracks in Germany or
Japan, trains offer travelers a chance to sit back and relax as they ride
through some of the world's most incredible scenery.
But often the stations the trains depart from are an attraction in their
own right, counting among the world's most beautiful pieces of
architecture.
Hamburg-based architectural data company, Emporis just released a
list of 11 of the world's most spectacular train stations.
"Increasing numbers of cities are adorning themselves
with eye-catching station buildings that, with their
unconventional roof structures, bright colors and
extravagant shapes, become unique architectural
landmarks of those cities," the report says.

The 11 stations include the artistic Hundertwasser
Bahnhof in Germany, decorated in the style of artist
Friedensreich; futuristic Gare de Liege-Guillemins in
Belgium, with its "gigantic arched roof that spans the
entire length of the station"; and the soon-to-be-
completed World Trade Center Transportation Hub in
New York "that will set new standards in station
architecture."
The report adds that historical stations are now being
eyed for elaborate and unusual renovations.

King's Cross in London and Gare de Strasbourg in France, for instance,
are among stations that are now part modern art and part historical
landmarks.
Meanwhile, architectural masterpieces like Grand Central Terminal in
New York and Chhaatrapati Shivaji Terminus in Mumbai are equally
as impressive today as they were when opening in 1913 and 1888,
respectively.
Check out the above gallery for Emporis' full list of spectacular train
stations.

Beyond Pistorius: rise of 'cyberathletes' could change sport as we know it

Andy Lewis' dream died when he was 16. Just out of
school, the Englishman had been accepted for an elite traineeship with
the army when he was hit by a truck, which resulted in most of his left
leg being amputated.
The available prosthetics were basic and uncomfortable, severely
restricting his movement. For over a decade, he could not run.
"The legs were too heavy and manufacturing companies didn't
understand what materials I needed," Lewis recalls.
Now 31, Lewis is fresh from winning a gold medal at the Madrid World
Paratriathlon in September. The achievement owes much to his
determination to succeed, but technology has also finally caught up with
his ambition.
Lewis won the race using an Ottobock S380 - the first above-the-
knee prosthetic leg specially made for athletes. A lightweight, shock-
absorbing frame allows for greater speed and comfort, and a flexible
knee joint provides range of movement and versatility that enables
Lewis to make rapid transitions from the pool to bike to track -- which
shaved critical seconds off his winning time.
But when we meet at his training center in Chesham,
on the outskirts of London, the champion is impatient
for further progress.
"By the Paralympics in 2016 I can envisage a lot of
new legs coming out...The knees are getting smaller,
the legs will have microprocessors, and you will be
able to press a button to change foot for the different events."
Lewis also hopes to have a 3D-printed socket to avoid some of the
bruising he suffers in competition.
To his support team at Pace Rehabilitation , the new champion is a
symbol of a revolution in prosthetics, which is transforming lives and
sporting competition.
"There have been major changes in the last two to three years," says
Pace's head prosthetist Jamie Gillespie. "It used to be that there were
only two types of running blade, but companies are now offering a
greater range for different competitions, adjusted to boost performance,
so the challenge now is to find the right blade for the right person for
the right sport."
Previous models were generally too painful for athletes with prosthetics
to run over 200 meters, but Gillespie notes that Oscar Pistorius rose
to prominence at 400 meters. As the possibilities multiply for
disabled athletes, so too does participation, competition, and standards,
which encourages manufacturers to develop ever-better equipment.
Pace's clients include numerous Paralympic athletes, and they work
with some of the most advanced new prosthetics. These include
Ottobock's new Genium X3 , widely regarded as the most advanced
prosthetic leg in the world, co-developed with the US military and
fitted with a micro-processor that adjusts for the user's stride pattern,
different types of movement from jogging to climbing stairs, and a
range of terrains.
Another client, skier Jozef Metelka, became the first European to
receive a power assisted ankle system from Biom last year, which
allows him to move faster and use less energy.
As the equipment improves, athletes with prosthetics have achieved
some startling feats, even out-performing able-bodied athletes.
Amputee long jumper Markus Rehm won the German national
championships with a jump of 8.24 meters on carbon fiber blades,
before the athletics federations controversially excluded him from their
squad, claiming he could have an unfair advantage.
