Firms must use the KDOT prequalification form to provide this documentation. KDOT 1050 Prequalification Category Definitions (Blue Book) can be found at Consultants may create a team to meet the prequalification requirements. All firms doing business with KDOT must be registered and in good standing under the laws of the State of Kansas at the time of contracting and must comply with applicable state and federal laws, rules, and regulations.

Background and Scope of Pavement Design Services

This scope of services is for a consultant to enter into an agreement with KDOT to perform pavement designs and write Reports of Pavement Investigation on KDOT projects.

Anticipated Consultant Scope of Pavement Design Services

Perform pavement designs and Write Reports of Pavement Investigation

The consultant is required to complete the following tasks in performing a pavement design and writing a pavement report:

  • Gather preliminary information from KDOT.
  • Perform pavement investigation using AASHTO 1993 pavement design software or spreadsheet.
  • Perform preliminary surfacing recommendations.
  • Prepare District Comments memo containing preliminary surfacing recommendations and send to the appropriate district.
  • Prepare final surfacing report incorporating comments received from the district.
  • Send report to Surfacing Selection Committee.
  • Set up Surfacing Selection Committee meeting to select project surfacing.
  • Obtain approval of selection from Deputy Secretary/State Transportation Engineer.
  • Send results of selection to concrete and asphalt industries.

Background and Scope of Coring Pavement

Pavement Core Sampling. This scope of services is for a consultant to enter into an agreement with KDOT to perform a pavement investigation by obtaining existing pavement cores on KDOT projects.

Anticipated Consultant Scope of Coring Pavement

The consultant is required to have the following equipment at a minimum to successfully perform the required tasks:

  • Appropriate PPE equipment (e.g. vest, boots).
  • Distance Measurement Instrument (DMI) or equivalent.
  • Milwaukee Core Drill or SIMCO Hydraulic Core Drill (Trailer Mounted) or equivalent.
  • Dynamic Cone Penetrometer (DCP).
  • Measuring wheel.
  • Tape measures.
  • Tamper (manual hammer to compact Cold HMA mix).
  • Shovels.
  • Plastic bucket for cold HMA mix.
  • Large core bags to place cores in after being cut.
  • Tags to label cores after removal from core hole.
  • Plastic twist ties to close bags.
  • Hoses to hook up water source to core drill.
  • Shop vacuum (remove water from core hole).
  • PermaPatch or patching material to backfill core holes.
  • XX Gauge wire or other tools to assist in removing core from hole (if necessary).
  • Minimum of four to six 4¼” diameter x 36” length core barrels.
  • Water truck that holds a minimum of 800 gallons or more.
  • Digital camera and video camera.

The core drill will need water to run properly. The consultant can fill up the water tank for the core drill at the nearest KDOT Sub-Area shop prior to beginning the coring operation.

Core Locations

The first task is to develop a core location spreadsheet. At a minimum, the core location spreadsheet should contain the following information:

  • Core Number
  • County reference post (Milepost).
  • State reference post (Milepost).
  • Direction (e.g. NB, SB, WB, or EB).
  • Distance from existing centerline of lanes in each direction.
  • Depth of hole.
  • Depth of core.
  • Remarks.

For a 2-lane highway mainline pavement, KDOT requires two cores to be cut from the existing pavement per mile. Core locations should be selected randomly and alternate between lanes. For a 4-lane divided highway mainline pavement, KDOT requires two cores to be cut from the existing pavement per mile per side. Two cores should be cut from the existing pavement in both set of lanes over a one-mile length. Core locations should be selected randomly and alternate between driving lane and passing lane to obtain uniform coverage. Core locations may be adjusted to avoid interfering with side road locations and drainage structures.

For shoulders, KDOT requires one core per mile per side to be cut from the existing paved shoulders.

For ramps, KDOT requires three cores to be cut in the traveled way evenly spaced along the ramp.

The second task is to utilize Google Earth or equivalent software to create an overhead map of core locations based on the core location spreadsheet. The locations shown on the overhead will not be exact but should be as close as possible to the actual locations.

Both the core spreadsheet and the overhead map of approximate core locations should be submitted to the supervisor in charge of the traffic control set up a minimum of seven days prior to the proposed field work dates.

Work Zone Limitations

Before determining field work dates, the consultant is required to contact the District Area Engineer to verify the work restrictions outlined below.

  • Any work requiring a single lane closure on the mainline or any ramp cannot be performed between 5:00 a.m. – 9:00 a.m. or 3:00 p.m. – 7:00 p.m., Monday through Friday.
  • Any work requiring multiple lanes to be closed or a ramp closure must take place between 7:00 p.m. and 5:00 a.m.

Traffic Control

One alternative is for the consultant to subcontract with a contractor to supply traffic control including message boards, signs, delineators, manpower, and vehicles while completing the coring operation.

Another alternative is to contact the KDOT Sub-Area shop supervisor and ask if KDOT could provide traffic control during the core sampling operation. All KDOT traffic control standards, manuals, and policies will apply.

Coring Operation Items

During the coring operation, a video should be made of the core barrel extracting the pavement core. The inside of the core hole should be photographed.

After the core is cut and removed from the core hole, the consultant shall label the core with a tag that contains the following information:

  • Project number.
  • County reference post (Milepost).
  • State Reference post (Milepost).
  • Distance from centerline of lanes.
  • Core length.
  • Hole depth measurement (Top of existing paved surface to bottom of core).

Two tags with the same information will be made.

The following information is required to be noted after the core is extracted from the hole, but before moving to the next core hole location. The information may be noted on the other side of the tag:

  • Surface distress nearby.
  • Distance of core location to nearest crack recorded to the nearest inch.
  • If core location is over a surface distress, provide a description of the surface distress.
  • If surface distress nearby or at core location is severe, include video or photographs of the distress.
  • Breaks in the core as it came out of the core barrel or after the core was extracted from the core barrel.
  • Approximate thickness of base material or soil removed from core hole.

It is recommended to have chalk on hand to mark all pieces of the core starting at the top of the core and working to the bottom. It is required for each piece of core to be labeled.

A photograph of the core should be taken before placing in bag.

One tag containing the core information will be placed inside the bag with the core. The second tag will be placed outside the bag with the twist tie.

Before filling the core hole with patching material, a DCP test for the subgrade should be conducted on every core hole location. The guidelines KDOT uses for depth of the DCP test are as follows:

  • If the old plans or historical pavement records indicate a treated subgrade is present, the DCP test should continue until three values in a row are the same or a depth of 18 inches is reached.
  • If the old plans or historical pavement records indicate no treated subgrade is present, the DCP test should continue until three values in a row are the same or a depth of 12 inches is reached.
  • If the old plans or historical pavement records indicate aggregate base is present, the DCP test should continue until three values in a row are the same or a depth of 18 inches is reached.

The DCP readings can either be recorded on the attached sheet provided by KDOT or can be submitted electronically in Microsoft Word or Excel format.


The deliverables that are required include the following:

  • Mainline core samples.
  • Shoulder core samples.
  • At interchanges, core samples from interchange ramps and ramp shoulders including side roads.
  • DCP Test raw data for all core holes in PDF, Microsoft Word, or Microsoft Excel format.
  • Notes or other information noted on tags or elsewhere during coring operation in PDF format.
  • Video or photographs of surface distresses in PDF format quality.
  • Video of core extraction.
  • Photograph of cores in PDF format quality.
  • Photograph of core holes in PDF format quality.

Therefore, KDOT is seeking to execute on-call agreements with a number of highly qualified firms, one of which may be selected on a task-by-task basis for specific assignment to be detailed in a Task Order/Work Order issued under a four-year term on-call agreement.
