S.P. DETERMINATION AND EXTENSION OF CONTRACT TIME (CALENDAR DAY)

(05-26):

Subsection 108.7, Determination and Extension of Contract Time, is amended to include the following:

The contractor shall document for each month of scheduled construction, the occurrence of adverse weather conditions having an impact on controlling items of work. An adverse weather day is a previously scheduled or normally scheduled work day on which rainfall, wet conditions or cold weather will prevent construction operations on the controlling work activity from proceeding for at least 5 continuous hours of the day or 65 percent of the normal work day, whichever is greater, with the normal working force engaged in performing the controlling item of work. If the contractor submits a written request for additional contract time due to adverse weather conditions, the contractor’s request will be considered only after the Department agrees with the days and then only for adverse weather days in excess of the allowable number of days per month stated below.

Adverse weather days will be documented by the Engineer and agreed upon monthly. Adverse weather days will be prorated for partial months when a work order or final inspection is issued other than the first or last of the month and agreed to by the Department. If the contractor is being considered for disqualification by the Department, an equitable adjustment in contract time may

D-6 be made at the end of the original contract period, including all days added by approved change orders. Contract time will be adjusted by comparing the actual number of adverse weather days to the statistical number of adverse weather days over the specific time period per the table below.

The resulting number of adverse weather days will be multiplied by 1.4 to convert to calendar days. Adjustments for adverse weather cannot result in a contract time reduction. Once adjusted, a new adverse weather day accounting will begin using the adverse weather conditions having an impact on the controlling items of work, in excess of the allowable number of days per month stated below. A second and final contract time adjustment will then be done at the final acceptance of the project. An adjustment in the contract time due to adverse weather will not be cause for an adjustment in the contract amount. There will be no direct or indirect cost reimbursement for excess adverse weather days.

The following are anticipated adverse weather days that the contractor shall include in each month of his calendar day construction schedule.

January 10 days May 5 days September 4 days

February 9 days June 6 days October 3 days

March 8 days July 6 days November 7 days

April 7 days August 5 days December 7 days

Hold sliding forms rigidly together laterally to prevent spreading of forms.

Provide concrete of a uniform consistency exhibiting minimal bleed water and laitance.

Operate the slip-form paver with as nearly a continuous uniform forward movement as possible. Coordinate mixing, delivering and placing of concrete to provide uniform progress. Concrete plants shall have sufficient mixing capacity to provide such continuous delivery of concrete to enable the paver to advance at a minimum rate of 1.5 feet per minute. If it is necessary to stop forward movement of the paver, also

D-12 immediately stop the vibrator and tamping elements. If forward movement of the paver is delayed for a period, the engineer may direct fogging of fresh concrete. See 601.3.080 for construction joint requirements. Apply no outside tractive force to the machine except as controlled from the machine.

B. Stationary Side-Form Method

Deposit concrete as near as possible to forms and joints assemblies without disturbing the form or joint assembly.

Use vibrators to consolidate concrete against and along the faces of all forms and the length and both sides of all joint assemblies. Limit vibrator operation to 5 seconds in any one location.

Section 601.3.110 is deleted and replaced with the following:

601.3.110 SURFACE TOLERANCE (IRI)

A. General

This subsection outlines the measurement of surface roughness, quality control requirements, corrective actions, and acceptance criteria for PCCP. Use the

International Roughness Index (IRI) to determine the amount of roughness in a measured longitudinal profile. In the direction of travel, measure the longitudinal surface profile in inches per mile and report as the IRI; all in accordance with DOTD

TR 644.

B. Equipment

In accordance with TR 644, furnish a DOTD certified inertial profiler for quality control and acceptance testing. A listing of DOTD certified profilers can be found on the DOTD

Materials and Testing Section website. The inertial profiler shall measure both wheel paths simultaneously with laser height sensing equipment at a constant speed within the certified range. Due to the surface texture of PCCP, lasers with a footprint greater than a single point are recommended for accurate readings.

Furnish a 10-foot metal static straightedge for quality control and acceptance testing for transverse cross slope, grade, and individual longitudinal bumps in excess of 1/4 inch in 10 feet. Additionally, bumps are not to exceed 1/4 inch in 10 feet for non-IRI pavements including but not limited to bike paths, detour roads, parking areas, sidewalks, turning lanes, turn outs, and shoulders.

C. Quality Control

1. Longitudinal Smoothness

Run the certified profiler and evaluate the raw IRI data using ProVAL to identify deficient areas for each wheelpath.

D-13

Any individual bump, which is more than 1/4 inch when tested with a 10-foot metal static straightedge, is a deficiency, which requires correction. Excessive rippling of the pavement surface will not be accepted. Ripples are small bumps (less than ¼ inch) in the pavement surface which usually appear in groups in a frequent and regular manner. No more than 12 ripples or peaks will be allowed in any 100-foot section. Rippling indicates a problem with the paving operation or mix that requires immediate corrective action by the contractor.

Modify operations to ensure the overall ride and individual bump requirements are met. Ensure the following quality requirements are met:

a) Produce IRI which meets the requirements for 100 percent pay in accordance with Table 601.3.110-1. Pavement operations resulting in continued surface tolerance penalties will not be allowed.

b) Correct all individual bumps which are more than ¼ inch when tested with a 10-foot metal static straightedge. The Rolling Straightedge Simulation in ProVAL may be used to help identify these bumps.

c) Correct ripples to the satisfaction of the Project Engineer. Report the Rolling

Straightedge Simulation for areas with 12 or more small, regular (less than 1/4 inch) bumps in a 100-foot section or for any areas in question.

Submit quality control IRI results to the Engineer for assessment as requested.

2. Correction of Deficient Areas

Correct deficient areas to meet the requirements of 601.3.110.C.1. Correct transverse, cross slope, or grade deficiencies to meet specifications. Make corrections by removing and replacing the PCCP full depth, or by diamond grinding and reestablishing surface texture and depth. Make corrections at no direct pay. In lieu of grinding, the Project Engineer may penalize the contractor $1,000.00 per individual bump or per localized area of excessive rippling.

For areas that will not be improved by grinding such as minor dips, extreme vertical curves, or other areas, the Project Engineer may waive the requirement to grind. In such cases, submit to the Engineer a written request to waive the requirement to grind and accept as constructed, along with a justification including a ProVAL screen shot for the area showing the Rolling Straightedge Simulation. Although omitted from corrective action, these areas still contribute to the overall IRI results.

D. Acceptance

1. Longitudinal Surface Tolerance Acceptance

Measure each mainline travel lane continuously from start to finish in the direction of travel for the project’s entire length. Perform the measurement under the observation and in the presence of the certified DOTD inspector. For projects that qualify for 102 percent pay, in accordance with Table 601.3.110-1, the Materials and Testing Section will verify the testing results. Measure the surface tolerance for acceptance at the completion of the project after all corrective actions.

D-14

Profiler system parameter settings shall be verified before and during each run by the DOTD inspector. The inspector will witness and document the daily setup procedure and pre-operation tests performed by the contractor in accordance with the manufacturer’s procedures and DOTD TR 644. A copy of the manufacturer’s setup, pre-operation, and general operating procedures for measuring surface tolerance, along with a copy of DOTD TR 644, shall be available at all times during measurement. Place a start and stop mark at the beginning and end of each travel lane so that the Department can rerun measurements.

The mainline longitudinal surface tolerance IRI specification requirements are in

Table 601.3.110-1.

The Department will view the mainline PCCP’s IRI raw data with ProVAL to identify deficient areas as defined by 601.3.110.C.1. Submit to the engineer for approval the locations and screen shots for any allowed uncorrected deficiencies in accordance with 601.3.110.C.2. Although grinding for some areas may be deemed unnecessary by the engineer the measured roughness for such areas will still contribute to the total IRI for the project. In addition, the Department will check for

1/4 inch bumps and excessive rippling at locations determined by the engineer.

Correct deficiencies in accordance with 601.3.110.C.2.

A DOTD inspector will be present for the acceptance testing and will immediately receive a copy of the raw data, the “*.erd” file and any files with information about the project, the operator, the equipment, the settings, daily pre-operation results, and a copy of the IRI results via USB flash drive. In addition to the data transferred by

USB storage device, provide the engineer a paper copy of the IRI report. Acceptance for the project will be in accordance with Table 601.3.110-1. The Department may elect to perform and utilize independent ride quality test results for acceptance at any time.

2. Exclusions

Take the IRI acceptance measurement in its entirety, without exclusions. The

Department will then review the profile report obtained for each lane. The project engineer will isolate or exclude sections of the profile that adversely affect the average IRI beyond the contractor’s reasonable control. These include the following:

a) Bridge ends and sections within 150 feet of bridge ends

b) Wheelpaths adjacent to curb and gutter sections

c) Wheelpaths adjacent to existing pavements

d) Manholes, catch basins, valve and junction boxes

e) Intersections or railroad crossings affecting the mainline roadway profile

f) Structures located in the roadway which cause abrupt deviations in the profile

g) Ramps less than 1,500 feet and turn lanes

D-15

h) Sections within 200 feet of the project limits if the limits begin or end at an intersection

i) Other sections where the project engineer determines that attaining smoothness is beyond the contractor’s reasonable control.

The roughness in excluded areas will not be included in the total IRI used for pay determination, but shall meet the requirements of 601.3.110.C.

The quantity represented by the roadway length excluded will not receive any bonus pay adjustment for surface tolerance.

Section 601.3.130 is deleted and replaced with the following:

601.3.130 OPENING TO TRAFFIC

Allow traffic on the pavement after 14 days or when test specimens, complying with 601.3.070, attain a compressive strength of 3,000 psi when tested in accordance with DOTD TR 230, or when high flexural strength is specified, a flexural strength of 480 psi when tested in accordance with ASTM C1074. Saw initial stress relief joints and clean the pavement prior to opening to traffic. If full width joints are cut, seal before opening to traffic.

601.3.140 ACCEPTANCE REQUIREMENTS

A. General

Conduct sampling for DOTD testing on each pavement lot for thickness, concrete strength, and surface tolerance. Sample in accordance with the DOTD Sampling

D-16

Manual. Correct all pavement that is obviously defective, or remove and replace to full depth, to the satisfaction of the engineer. Times and locations will be established by the engineer.

A pavement lot is an identifiable area of approximately 4,000 square yards paid under the same item. The final area of pavement placed is a lot if it is at least 2,000 square yards; otherwise, it will be included in the previous lot. The engineer may redefine the lot limits when sequences of construction prevent timely sampling and testing.

Consider intersections, entrances, crossovers, ramps, and any other identifiable placement as separate lots.

B. Concrete Strength and Thickness

1. Compressive Strength

Determine the 28-day compressive strength and thickness of pavements from hardened cores. The Department, in accordance with DOTD TR 225, will identify random concrete core locations and determine the diameter, thickness, and strength.

Cut the cores in the presence of a DOTD representative between 14 days and 26 days after concrete is placed. The DOTD representative will take immediate possession of the cores for thickness and strength determinations. Notify the District

Laboratory Engineer at least five days prior to the start of coring operations.

The engineer will divide each pavement lot into five equal sections. Obtain one core from each section after meeting surface tolerances. Provide additional cores required by the Department to isolate thickness, strength or other pavement deficiencies, or for recutting of deficient cores at no direct pay. Patch all core holes using an approved pavement or structural concrete mixture meeting the requirements of

Section 901. Patch the core holes immediately after coring operations. Finish the surface of the patch to match the surrounding pavement. Include the cost of patching the core holes in the bid price of the concrete coring.

When the average strength for the lot is less than 4,000 psi, the contract unit price will be adjusted in accordance with Table 601.3.140-1. When an individual core indicates compressive strength less than 3,000 psi, remove, and replace the entire deficient section with concrete of the specified quality. If the Chief Engineer determines that the concrete may be left in place, payment for the quantity of concrete represented by the deficient core will be made at 50 percent of the contract unit price. Payment for the remainder of the lot will be made in accordance with

Table 601.3.140-1 based on the average compressive strength of the remaining sections.

2. High Flexural Strength

When high flexural strength (modulus of rupture) is specified, submit a contractor-controlled curing and delivery plan to the engineer for approval.

Determine the flexural strength using the maturity method according to ASTM

C1074. The pavement lot shall be divided into five equal segments, and a minimum of two maturity sensors will be placed in each segment. The Department, in accordance with DOTD TR 225, will identify random locations to place the maturity sensors.

When the average flexural strength for the lot is less than 600 psi, the contract unit price will be adjusted in accordance with Table 601.3.140-1. When a maturity sensor indicates flexural strength less than 480 psi, remove, and replace the entire deficient section with concrete of the specified quality. If the Chief Engineer determines that the concrete may be left in place, payment for that segment will be made at 50 percent of the contract unit price. Payment for the remainder of the lot will be made in accordance with Table 601.3.140-1 based on the average flexural strength of the remaining sections.
