Railway track construction equipment and machinery. Will the construction project include field events? Most track projects built today include construction of a complete set of field event facilities: Most owners want a complete project and it is more economical to construct all of these field events at the same time that the track is constructed than it is to have a contractor return and construct them at a later time.
During the design phase, the design team must consider where the field events will be located. Placing the field events in the infield of the track may facilitate spectator viewing, but may mean more traffic over the runways, and sideline congestion for other sports. This will mean more maintenance and a shorter life span.
In addition, every effort must be made to design the jumping events with the wind for athlete safety; cross winds are particularly dangerous. Throwing events are preferably located so that participants are throwing into the wind. Likewise, for safety reasons it is essential that high jump and pole vault runways be located so that the athlete does not have to look into the sun or into artificial lighting.
Event by event design considerations add significantly to the complexity of designing the overall project and have a significant impact on the size of site required. Choosing the right contractor can determine the ultimate success of your track facility. A knowledgeable and experienced contractor can help you, the owner, make the right decisions resulting in a quality project.
Track construction is a highly specialized field within the construction industry. It is vital that the contractor you choose be familiar with the current marketplace, as well as with the type of surface you intend to install. How do you find a qualified contractor? One way is to contact the ASBA. In addition, the ASBA conducts a certified builder program. Experienced contractors earn the Certified Track Builder CTB designation by completing a number of projects and by passing a certification examination.
CTBs must recertify every three years.
RFIs, Mail & Forms
The Association also conducts an inquiry program, requesting information on your behalf from contractors and suppliers who have the answers to your questions. See our online list of Certified Track Builders. Another way to locate such specialists is by contacting municipal facilities and schools which have recently completed track projects.
Ask whether or not they would recommend their contractor and, further, ask some specific questions. Was the job completed on time? Did it meet the owner's expectations?
Project cost management software that lets you measure performance & forecast with confidence
Were there any hidden costs? Was the contractor able to solve any problems which arose during construction?
If there have been any post-construction problems, was the builder responsive in taking care of them? How does the track look? How does it perform? Remember, both experience and reliability of the prospective builder are important. If you, the buyer, are to make the right decisions regarding a track project, becoming a knowledgeable consumer is the first step. Asking questions is not only smart, it is essential.

Box Indianapolis, IN Box Indianapolis, IN Fax: Basically, the success of a track construction project will depend on: Proper site analysis; Quality design and engineering; Expert construction including construction of proper drainage, a stable base and a quality synthetic surface; and Accurate marking.
There are three basic shapes for tracks: A non-equal quadrant track has two equal curves and two equal straightaways that may be either shorter or longer than the curves. The IAAF specifies a type of this track that has straightaways of This type of track is found in many existing stadiums and may be the track of choice, if space allows.
It accommodates an American football field and its wider radius favors runners, enhancing performance.

The double bend track has a compound radius curve usually two small curves and a large curve formed by three different radii and, together, forming one complex curve with a major bend not to exceed 60degrees at each end. This type of layout provides for the inclusion of a much wider playing field such as a soccer field and allows for the construction of a m track on a site that is not as long and wide as that required for the other track configurations. A equal quadrant track has two l00m straightaways and two l00m curves. In the past, many tracks were built with this design.
Today, however, few tracks are built in this configuration for several reasons: A wider radius allows greater flexibility in placing fields, especially soccer pitches, within the track oval; A wider radius, such as is found on the International Standard and Double Bend tracks, favors runners and enhances performance. Consider a design professional. An experienced contractor or design professional can help you to assess your proposed site, but the following general considerations should be met: There are a number of other important considerations in site selection.
Does a potential site allow for proper drainage and storm water management? Water should drain away from the track. It is best to locate a track on a relatively level plain, higher than surrounding areas.

Many tracks are built on low sites; however, additional filling or drainage work required by a low site may add substantially to construction costs. Even under the best site conditions, tracks should be constructed with an adequate interior drainage system to remove field irrigation overspray and storm water which may drain from the track and from the playing field. Proper drainage is an essential part of the track design. Is the site reasonably level? While the track will be sloped slightly laterally for drainage, the track must be level in the running direction. What type of soil exists at the site?
The best soil is hard, well-drained and non-heaving. Locations with peat, clay, topsoil, shear sand or other unsuitable materials at a depth of 8"" should be avoided, if possible. These are sites with poor drainage, bad subsoil and other challenges. Site problems, such as the need to establish a level plane or restructure the subbase, can be overcome with expert design and engineering, but this will add to the cost of the track. Is the site accessible for construction? Track construction requires the use of heavy equipment which must get to the site.
The need to move or to avoid obstructions, such as fences, trees, buildings, grandstands and bleachers, may add to the cost of construction. Where are underground utilities electricity, water, gas, telephone, sewer, etc.
Buyer's Guide for Track Construction
While the finished facility will require utility service, it is far easier to avoid constructing the track over underground utilities. Where is the prevailing wind? A track facility should be built with straightaways parallel to prevailing winds. This is especially important for dashes, hurdle races and planning full field events. Is the site accessible to the public?
Are roads, parking facilities, walkways, bathrooms, water fountains, seating and other facilities adequate for spectators? Choose a surface and develop working specifications. Existing asphalt-bound tracks in good condition are often sealed to prolong their life. Make specific choices regarding amenities and accessories to be included in your track project.
