I.    Identifying Reinforcing Steel

Reinforcing steel is known by the bar number. Bar numbers are based on the
number of 1/8 inches included in the nominal diameter of the bar. For example,
a #4 bar is equal to 4/8 or 0.500 Diameter (inches).

American steel is marked by four identifying marks:
  1st - Producing Mill (usually an initial or symbol)
  2nd – Bar Size Number (#3 through #18 [#10 through #57])
  3rd – Type (S for Billet, A for Axle, R or ‡ for Rail)
  4th – Minimum Yield Strength Designation (60,000 psi or higher)
  • 60 [4] or one (1) line for 60,000 psi [420 MPa] strength
  • 75 [5] or two (2) line for 75,000 psi [520 MPa] strength

B.    Tags and Mill Certifications - along with the markings on the reinforcing
      steel bars, each shipment should include tags and mill certifications.

      Tags - Tags should be attached by wire to each bundle of reinforcing
      steel. They should be made of durable, waterproof material, and marked
      in a legible manner.

                                Examples of Tags




Mill Certification - Producer’s Mill Certification should be attached to each
shipment of reinforcing steel. The name on the Mill Certification should match 1st
Mark on reinforcement bar

II.    Sampling Reinforcing Steel

Certification and testing for steel is required in Specifications Section 931.
Collect certifications for every shipment and retain them according to the FDOT
Records Retention procedure. Take reinforcing steel samples at the time the
steel is installed and submit them to the State Materials Office for testing along
with the required document.

A.     Take one sample for every 80 tons, no matter what pay item or pay items
       are being used. Do NOT send a sample for each size or for each pay
       item, just one sample representing 80 tons of steel. If your project has
       160 tons of steel, send two samples, etc.
       One sample is equal to:
       1.      Three pieces of rebar:
               a)      Sample the most frequently used size
               b)      Make sure the pieces are a minimum of seven feet long
               c)      Take the pieces from the bundle of reinforcing steel and not
                       the splice bar
       2.      A tag
       3.      A mill certification

B.     Complete a Sample Transmittal Card. Submit a separate completed
       sample transmittal card printout for each steel sample you send to the
       State Materials Office.

C.     Log the sample into LIMS. Make note of the LIMS Sample ID for your
       records. Print the Sample Transmittal Card report with the LIMS Sample
       ID. Keep the completed Sample Transmittal Card from B) for your
       records.

D.     Send one piece, the tag, the mill certification and the printed Sample
       Transmittal Report from LIMS to the State Materials Office. Keep two
       pieces at the project site in case of a failure.

NOTE: The State Materials Office frequently receives steel samples with no
identifying documentation attached. Since most delivery services know that
reinforcing steel gets delivered to the State Materials Office, it is common for the
State Materials Office to receive a single piece of reinforcing steel with no
paperwork.

Without the C-22 card with the LIMS Sample Id, the tag and the mill certification,
State Materials Office can NOT process the sample. Your sample will remain in
LIMS as “Logged, Awaiting Receipt” and you may have a Final Project Materials
Certification Exception for the steel testing frequency. Attach the documentation
to the steel sample in such a way that it will remain with the sample through the
shipping and delivery process.

1.    Project-Pay Item-Matl Id-Level-Year/Authority
      These five fields are tied together in LIMS. Clicking on the drop down
      arrow by any of them will generate a dialog box with all five fields. By
      choosing any option, you populate all five fields.

1a.   Project ID – Enter the correct Project ID for your sample. Click on the
      drop down arrow to proceed. Project, Pay Item, Material ID, Sample
      Level, and Spec ID fields are connected in LIMS. When you click on the
      Project drop down arrow, a dialog box will appear with all of these fields.
      When you choose an option from the dialog box, LIMS fills in all five fields.

1b.   Pay Item Number – Choose the combination with the pay item the
      sample represents. If the sample represents more than one pay item,
      choose the project / pay item combination that has the most reinforcing
      steel. You can add any other pay items in the notepad.

1c.   Material ID – Select the combination with 180L for reinforcing steel.




Reinforcing Steel Sample Instructions (June 2009)                     Page 7 of 14
NOTE: If the correct project / pay item / combination with 180L id is not
available, make sure that the one you select has the correct pay item and sample
level. Since these materials are logged under Sample Level V, do not chose a
project / pay item combination with a Q Sample Level. If there is no project / pay
item combination with the correct sample level, contact the FDOT service desk
and request that the correct project / pay item / material id / sample level be
added to your project. By choosing a project / pay item with the incorrect sample
level, you may receive a conflict of interest error later.

1d.       Sample Level – For reinforcing steel, the sample level is V.

1e. Year/Authority – Choose the combination with:
   • 200801/STD Spec 931 for projects entered in LIMS after 01/2008 with
      English pay items




      •   200707/STD Spec 931 for projects entered in LIMS before 01/2008 with
          English pay items




      •   200207/STD Spec 931M for projects with metric pay items




NOTE: LIMS will filter the list if you supply the correct information. To find the
correct combination more quickly from a shorter list:
a.     Enter the financial project id and material id and sample level in the
       correct fields.
b.     Click on the drop down arrow next to the Level field.




Reinforcing Steel Sample Instructions (June 2009)                        Page 8 of 14
The pay item dialog box will appear with only those pay items with that material
id assigned. Click on the correct combination to highlight it. Click OK to select it
and populate the fields.




2.     Resolution – Y/N? This field defaults to yes. Steel is not a Contractor
       Quality Control item. Leave it as N.

3.     Matl ID On Spec-Level-Auth-Year
       These four fields are tied together in LIMS. Clicking on the drop down
       arrow by any of them will generate a dialog box with all four fields. By
       choosing any option, you populate all four fields.

3a.    Matl ID On Spec – If the correct project / pay item combination with a Matl
       Id of 180L is not on the project / pay item drop down list, click on the drop
       down arrow. Choose the combination of 180L.

3b.    Level – V

3c.    Auth – STD Spec 931 (English) or STD Spec 931 M (metric).

3d.    Spec Year – 200801

NOTE: Only use the 200801 option for English pay items in the Material Id (on
Spec) field.

IV.       Reinforcing Steel Sample Processing

Once you’ve logged the sample into LIMS, send it to the State Materials Office.
You can find information on submitting samples to the State Materials Office on
the State Materials Office website at:
http://www.dot.state.fl.us/statematerialsoffice/administration/resources/library/publications/laboratory/sampledeliveries.pdf


When the sample is physically received at the State Materials Office, laboratory
personnel will receive the sample in LIMS, perform testing, enter the test results,
validate and approve the sample provided all identifying documentation has been
included.

The normal turn around time for the entire process is around ten working days.
Be sure to check the sample status using the Sample Status by Sample ID
screen under the Status tab in LIMS before calling the State Materials Office. If
after ten working days, your sample is still awaiting receipt, contact the State
Materials Office Physical Laboratory.

V.        Steel Sample Failures

If the reinforcing steel sample fails, State Materials Office laboratory personnel
will contact the project personnel by phone. If you are contacted by the State
Materials Office that the reinforcing steel sample failed:

1.        Send the two pieces you set aside in case of failure to the State Materials
          Office for retesting with a copy of the original C-22 Card with the LIMS
          Sample ID written in the upper left hand or a copy of the Sample
          Transmittal Card C-22 report with the LIMS Sample Id securely attached
          to the two steel pieces.

2.        Do not log in a new sample into LIMS. The State Materials Office will
          retest the material on the same sample using the same LIMS Sample Id.

3.        The State Materials Office will notify you of the results of the retest.
