Class 3 Tracks
Class 3 Markings and Slopes Certification for Running Tracks
Instructions to Surveyor
Version 1/11/10
1.1 Intended use.
This document is intended to serve as verification to the owner of the facility
that their track meets the requirements of the appropriate governing body in
the categories described below. Class 3 Certification is intended to be completed
as an integral part of the striping, and not as an “after the fact” undertaking.
For tracks requiring certification after the striping is complete, use Class
5 Certification. This form has been published by the American Sports Builders
Association (ASBA) to assist owners of track facilities in verifying that their
track facility meets the official requirements of the relevant governing body
of the sport. The ASBA makes no representation with respect to the requirements
of any governing body, nor does it warrant or guarantee the accuracy or correctness
of the measurements or conclusion of the certifying party.
1.2 Completion of the form.
This form may be completed by a competent measurer, such as a Registered Land
Surveyor, Professional Engineer, Certified Track (CTB), or an experienced track
striper. Note that the Report of Slopes (see item 3.6 Track and Event Area
Slopes) should be completed before the surface is installed, to allow for slope
corrections if necessary, prior to track surface installation.
2.1. Slopes of track and event areas.
The maximum inclination should be one percent (1.0%) across the entire width
of the track and all runways. The maximum downward inclination permitted
in the running direction for the track, the running direction for all runways,
measured over the full length of each, should not exceed one tenth of one
percent (0.10%). For high jump, the maximum inclination should not exceed
four tenths of one percent (0.40%) in the running direction towards the center
of the crossbar. Consideration: when a renovated facility falls outside these
requirements the use of Class 4 or Class 5 Certification may be applicable.
2.2. The track oval.
The 400m oval typically consists of two semi circles of equal radius, which
are joined by two straights of equal length.
The inside of the oval track shall be bordered with a white line of 0.05m wide
and may include a curb of suitable material, approximately 0.05m in height
and width, installed on top of the white line. The theoretical running length
of the oval shall be measured on the surface of the track along the theoretical
path of the runner (known as the measuring line). The painted line is to be
located 20cm inside the 400m measuring line (toward the inner field) if no
curbing is to be installed over the line. If curbing is to be installed over
the line, the painted line is to be located 30cm inside the 400m measuring
line. All other lane lines are to be located 20cm inside the corresponding
measuring line for that lane. The actual length of the 400m measuring line
should not be less than 400m, or more than 400.06m.
2.1. Slopes of track and event areas.
The maximum inclination should be one percent (1.0%) across the entire width
of the track and all runways. The maximum downward inclination permitted
in the running direction for the track, the running direction for all runways,
measured over the full length of each, should not exceed one tenth of one
percent (0.10%). For high jump, the maximum inclination should not exceed
four tenths of one percent (0.40%) in the running direction towards the center
of the crossbar. Consideration: when a renovated facility falls outside these
requirements the use of Class 4 or Class 5 Certification may be applicable.
2.2. The track oval.
The 400m oval typically consists of two semi circles of equal radius, which
are joined by two straights of equal length.
The inside of the oval track shall be bordered with a white line of 0.05m wide
and may include a curb of suitable material, approximately 0.05m in height
and width, installed on top of the white line. The theoretical running length
of the oval shall be measured on the surface of the track along the theoretical
path of the runner (known as the measuring line). The painted line is to be
located 20cm inside the 400m measuring line (toward the inner field) if no
curbing is to be installed over the line. If curbing is to be installed over
the line, the painted line is to be located 30cm inside the 400m measuring
line. All other lane lines are to be located 20cm inside the corresponding
measuring line for that lane. The actual length of the 400m measuring line
should not be less than 400m, or more than 400.06m.
2.3 Individual races.
The horizontal variance allowed for the individual races is between 1 and 1.0002
times the specified length along the measuring line for each lane.
The location of incidental markings, such as hurdles, steeplechase barrier
placements and baton exchange zones should be noted.
3.1 Surveyors Identification Data and Survey Conditions:
Complete the document for Report of Slope and/or Report of Measurement (whichever
covers your scope of responsibility). Attach valid certificates of accuracy
of instruments.
3.2 Oval Lines layout – before lane line
striping:
a. Locate the centers (radius points) of the two semi-circles.
b. Measure the distance between the centers of the two semi-circles. The deviation
from the desired value should not exceed +0.007 meters.
c. Place marks on the synthetic surface at the specified radius for the outer
edge of the inside line at points 1-13, which are 15 degrees between points.
These are the radius control points. At the same angles, place marks in the
same manner for all other lane lines.
d. Repeat this procedure for points 14-26. At the option of the contractor
and surveyor (if the two are separate), the surveyor may place controls for
all other lanes in these locations.
e. Measure the distance between points 13 and 14 (line AB). The deviation from
the desired value should not exceed +0.007m. Record the measured distance on
table 5.1.
f. Measure the distance between points 1 and 26 (line CD). The deviation from
the desired value should not exceed 0.007m. Record the measured distance on
table 5.1.
3.3 Oval Lines Verification – after painting the lane lines, before installing
the curb (if applicable):
a. At points 1-13 and 14-26, measure the distance between the radius control
points and the outer edge of the painted line. Record the measured deviations
on table 5.1.
b. Calculate the average deviation from the desired value of radius of curve
DA and BC. Record the average deviations on table 5.1.
c. Calculate the length of curves DA and BC, the length of the inside border,
the theoretical running distance of the track and the deviation of the theoretical
running distance from 400m following the instructions on table 5.2. If such
deviation does not exceed +0.06m (and is not short of 400m), the 400m oval
can be considered dimensionally accurate.
d. Although a table is not provided, the surveyor should verify that radii
for all lanes meet the same criteria as 3.3.c, and that the average line radii
do not vary more than .01m from the design radius when averaged at points 1
through 26, with no individual point varying more than .025m.
