INSTRUCTIONS FOR COMPLETION OF

PCC THICKNESS REPORTS

 

 

These instructions are for filling out the computer generated PCC thickness report forms available from the Office of Materials. The following information is entered on the INFORMATION INPUT tab.

 

Project #

Enter the project number listed on the plans.

 

Contract ID #

Enter the five-digit accounting ID found on the contract.

 

Project Units (in, mm)

Enter mm or in depending if the project was metric or English. Core measurements are entered in English units and converted to metric if “mm” is entered.

 

Design Thickness

Enter the contract thickness. Some projects may have more than one design thickness and therefore would require the use of more than one spreadsheet.

 

# of Sections on Project

Enter the number corresponding to the number of design thickness sections on the project.

 

This Section #

Enter the section number for this report (1, if only one design thickness)

 

# of Lots in This Section

This is a calculated number corresponding to the number of required cores.

 

Item Code #

Enter the item code number from plans for the pavement section.

 

Item Description

Enter the item code description.

 

Contract Price

Enter the contract unit price for the item.

 

Plan Quantity (yd^2/m^2)

Enter the quantity of the item, used to estimate the number of lots or cores.

 

Final Quantity (yd^2/m^2)

Enter the actual placed quantity of the item, used for payment.

 

Contractor

Enter the name of the contractor performing the work. If it is a subcontractor, list this after the contractor name.

 

County

Enter the county listed on the project plans.

 

After the County field, there are different fields to enter between the #Form130 for cores and #Form130MIT for MIT thickness. See below.

 

District Mat. Eng.

Enter the District Materials Engineer assigned to the project.

 

Project Eng.

Enter the project engineer responsible for the project.

 

Remarks

Enter general remarks as needed for information purposes.

 

The following inputs are used for reporting MIT thickness on Form #130MIT.

 

Subbase Type

Enter the subbase for the section tested. Subbase type is needed to determine correction for material that

 

Locations determined by

Enter the name of the person who determined the target locations.

 

Verification Measured By

Enter the name of the person testing the verification thickness

 

Verification Gage #

Enter the number of the gage used to test verification thickness.

 

IA Measured By

Enter the name of the person checking independent assurance (IA) thickness

 

IA Gage #

Enter the number of the gage used to test IA thickness.

 

Note: There are different spreadsheets for the T2 and T3 gages. Data downloaded from the MIT gage should be imported into a blank Excel sheet. Copy the data to the MIT DATA tab in the appropriate columns. T2 data should be left in metric units and T3 data should be in English units. Run the macros on the MIT DATA tab.  Review the data for any errors and rerun, if necessary. Independent assurance (IA) results may be added THICKNESS INPUT tab.

The following is an example of a #FORM130MIT thickness report.

 

 

 

The following inputs are used for reporting core thickness on Form #130.

 

Beginning Core #

Enter the beginning core number assigned by District materials when generating random locations. The first number designates the district the remaining four numbers are non-repeating and should be consecutive for each section Do not used dashes (example: 50125).

 

Ending Core #

Enter the ending core number assigned by district materials when generating random locations. The first number designates the district the remaining four numbers are non-repeating and should be consecutive for each section. Do not use dashes (example: 50176).

 

Sampled By

Enter the person responsible for sampling, witnessing, or obtaining the cores.

 

Measured By

Enter the person responsible for measuring the cores for verification.

 

Checked By

Enter the person responsible for independent assurance measuring.

 

 

Select the THICKNESS INPUT tab and enter the Date Poured, Date Measured, Station, Lane, distance from centerline (Dist CL), left or right side of centerline (Rt, Lt), and the nine point measurements in the cells shaded gray. ALL NINE POINT MEASURMENTS MUST BE ENTERED IN ENGLISH UNITS.

 

Enter District materials assurance measurements as well as remarks pertaining to individual cores are also entered on this worksheet.

 

When data has been entered in the THICKNESS INPUT worksheet it will automatically be transferred to the THICKNESS SUMMARY worksheet with calculations.

 

The only input that can be done on the THICKNESS SUMMARY worksheet is to enter and “X” for cores that are greater than the design thickness by three standard deviations. Cores that are greater than the design thickness by three standard deviations will display a highlighted red cell with a letter Y in the column labeled cores > 3 STDEV. The highlighted cores are the only cores eligible for removal if desired. To remove an eligible core an “X” must be placed next to the highlighted red cell with a letter Y. The number of cores allowed to be removed can be found on the THICKNESS REPORT worksheet. There are several safeguards to ensure that only an allowable number of eligible cores can be removed.

 

The THICKNESS REPORT tab is summary of the general project data as well as the thickness payment calculations are displayed. There is nothing to input on this sheet since all data is automatically transferred. 

 

Print the THICKNESS SUMMARY and THICKNESS REPORT.
