SECTION 011250 - MEASUREMENT AND PAYMENT WITH ASPHALT

1. GENERAL

SUMMARY

Measurement and payment for contract work will be made only for and under those pay items included in the Schedule of Items. All other work, labor, materials, equipment, and incidentals necessary to successfully complete the project will be considered as included in the payment for items shown. This section defines the method of measurements and basis of payment for work items listed in the Schedule of Items.

When more than one class, size, type, thickness, etc. is specified in the Schedule of Items for any pay item, suffixes will be added to the item number to differentiate between the pay items.

DETERMINATION OF QUANTITIES

The following measurements and calculations shall be used to determine contract quantities for payment.

For individual construction items, longitudinal and lateral measurements for area computations shall be made horizontally or corrected to horizontal measurement unless otherwise specified. Measurements for geotextiles, netting and erosion control blankets shall be along slope lines.

For excavation or embankment volumes, the average end area method shall be used to compute volumes. However, if in the judgment of the Contracting Officer (CO), the average end area method is impractical, measurement shall be made by volume in hauling vehicles or by other three-dimensional methods.

For Structures, they shall be measured according to neat lines shown on the drawings or as altered by the CO, in writing, to fit field conditions.

For items that are measured by the linear foot, such as pipe culverts, fencing, guardrail, piping, utilities, and underdrains, measurements shall be made parallel to the base or foundation upon which the structures are placed.

For aggregates weighed for payment, the tonnage shall not be adjusted for moisture content, unless otherwise provided for.

For standard manufactured items (such as fence, wire, plates, rolled shapes, pipe conduits) identified by gauge, weight, section dimensions, and so forth, such identifications shall be considered the nominal weights or dimensions. Unless controlled by tolerances in cited specifications, manufacturer's tolerances shall be accepted.

For bituminous material, volumes will be measured at 60F or will be corrected to the volume at 60F by using ASTM D1250 for asphalts. Emulsified asphalt will be measured at 60F, or measured by converting the gallonage at another temperature to gallonage at 60F by means of the following formula:

Gallons at 60F = Gallons at AF

1+0.00025 (AF - 60F)

* AF is the temperature of the material at the time the gallonage is measured.

For vehicular shipments, net certified scale weights or weights based on certified volumes will be used as a basis of measurement. Measurements will be adjusted when bituminous material has been lost from the vehicle or the distributor, has been wasted, or has otherwise not been incorporated into this work. Determining true weights of hauling vehicles shall be made by weighing the empty vehicles at least once a day at the times the CO directs. Each vehicle shall bear a plainly legible identification mark.

When bituminous materials are shipped, net certified weights, or volume corrected for loss of foaming, can be used for computing quantities.

Earthwork Tolerances - Adjustments of horizontal or vertical alignment, within the tolerances specified in this contract, or shifts of balance points up to 100 feet shall be made by the contractor as necessary to produce the designed sections and to balance earthwork. Such adjustments shall not be considered as "Changes."

UNITS OF MEASUREMENT

Payment shall be by units defined and determined according to U.S. Standard measure and by the following:

Acre: Make longitudinal and transverse measurements for area computations horizontally.

50lb Bag: Measurement will be for the actual number of 50lb bags of standard bentonite grout.

94lb Bag: Measurement will be for the actual number of 94lb bags of standard cement or grout.

Cubic Yard (CY): A measurement computed by one of the following methods:

Excavation, Embankment, or Borrow. The measurement computed by the average end area method from measurements made longitudinally along a centerline or reference line.

Material in Place or Stockpile. The measurement computed using the dimensions of the in-place material.

Material in the Delivery Vehicle. The measurement computed using measurements of material in the hauling vehicles at the point of delivery. Vehicles shall be loaded to at least their water level capacity. Leveling of the loads may be required when vehicles arrive at the delivery point.

Each (EA): One complete unit, which may consist of one or more parts.

Gallons (GAL): The quantity shall be measured by any of the following methods:

Measured volume in container.

Metered volume by approved metering system.

Commercially package volume.

Hour (HR): Measurement will be for the actual number of hours (or fraction thereof) ordered by the Contracting Officer and performed by the contractor.

Linear Foot (LF): Measurement of work along its length from point-to-point; parallel to the base or foundation. Do not measure overlaps.

Lump Sum (LS): One complete unit.

Mile: Measured horizontally along the centerline of each roadway, approach, or ramp.

Pound (LB): For sacked or packaged material, measurement will be the net weight as packed by the manufacturer.

Square Foot (SF): Measured on a plane parallel to the surface being measured.

Square Yard (SY): Measured on a plane parallel to the surface being measured.

Ton: Measured as a short ton consisting of 2,000 pounds.

METHOD OF MEASUREMENT

One of the following methods of measurement for determining final payment is designated on the Schedule of Items for each pay item:

ACTUAL QUANTITIES (AQ) - These quantities are determined from actual measurements of completed work.

DESIGNED QUANTITIES (DQ) - These quantities denote the final number or units to be paid for under the terms of the contract. They are based upon the original design data available prior to advertising the project. Original design data include the preliminary survey information, design assumptions, calculations, drawings, and the presentation in the contract. Changes in the number of units shown in the Schedule of Items may be authorized under any of the following conditions:

As a result of changes in the work authorized by the CO.

As a result of the CO determining that errors exist in the original design that cause a pay item quantity to change by 15 percent or more.

As a result of the Contractor submitting to the CO a written request showing evidence of errors in the original design that cause a pay item quantity to change by 15 percent or more. The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

LUMP SUM QUANTITIES (LSQ) - These quantities denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor to complete the job. They shall not be measured.

STAKED QUANTITIES (SQ) - These quantities are determined from staked measurements prior to construction.

VEHICLE QUANTITIES (VQ) - These quantities are measured or weighed in hauling vehicles.

PRICE ADJUSTMENT (for Out-of-Specification Bituminous Materials) Bituminous materials are defined as all types and grades of asphalt cement, liquid asphalt, emulsified asphalt, and dust oil.

If bituminous material fails one or more test requirements, and the Contracting Officer determines it is in the public interest to accept the material at a reduced price, the price reduction shall be based on the test results giving the largest percent price adjustment. The contractor may remove and replace the defective material or accept the adjustment.

The price reduction shall apply to all pay items affected.

Price adjustment will be based on samples taken in duplicate in accordance with AASHTO T40 under the supervision of the Contracting Officer. Samples shall be sent to an authorized laboratory. The laboratory shall test one of each duplicate sample and retain the other. When any test result is not within the specification limits, the laboratory shall immediately notify the Contractor, the supplier, and the Contracting Officer. The Contractor, after notifying the Contracting Officer, may check test the retained sample.

If the retained sample tests satisfactorily, the material will be accepted. If the retained sample also fails, the following schedule of price adjustments shall apply. The average of test values for the two samples will determine the basis for price adjustment, except when test results on the samples differ by more than the applicable AASHTO or ASTM Repeatability Unit; then, the test result numerically nearest the specification requirement will be used. (A repeatability unit is defined as D2S or D2S% limit for single operator precision described in ASTM C670.)

The schedule of price adjustments shall not apply to the following tests:

Bituminous materials failing to meet specifications for these tests shall be removed and replaced.

See Table 011250-1 for the schedule of price adjustments for bituminous materials that do not meet specifications.

Table 011250-1

Schedule of Price Adjustments for Out-of-Specification Bituminous Materials.

Application Deviation from Specification Limit Measured in Reproducibility Units*.

* A reproducibility unit is defined as D2S or D2S% limit for multi-laboratory precision described in ASTM recommended practice C670.

The Sieve Test (AASHTO T59) results may be exempt from the Schedule of Price Adjustments provided the contractor's quality assurance program includes checking the uniformity of bituminous spread rates in increments no greater than 1 foot over the width of the spray bar and variation between increments is no greater than 5 percent.

SECTION 013300 - SUBMITTAL PROCEDURES

1. GENERAL

SUMMARY

This Section includes administrative and procedural requirements for submitting Shop Drawings, Product Data, Samples, and other miscellaneous submittals. See Table 013300-1 for a summary of required submittals.

See other specification section within this package for additional requirements on submittal.

SUBMITTAL PROCEDURES

Coordination: Coordinate preparation and processing of submittals with performance of construction activities.

Coordinate transmittal of different types of submittals for related parts of the Work so processing will not be delayed because of need to review submittals concurrently for coordination.

The Contracting Officer (CO) reserves the right to withhold action on a submittal requiring coordination with other submittals until related submittals are received.

Processing Time: Allow enough time for submittal review, including time for re-submittals, as follows. Time for review shall commence on CO's receipt of submittal.

Initial Review: Allow 14 days for initial review of each submittal. Allow additional time if processing must be delayed to permit coordination with subsequent submittals. CO will advise Contractor when a submittal being processed must be delayed for coordination.

If intermediate submittal is necessary, process it in same manner as initial submittal.

Allow 14 days for processing each re-submittal.

No extension of the Contract Time will be authorized because of failure to transmit submittals enough in advance of the Work to permit processing.

Identification: Place a permanent label or title block on each submittal for identification.

Indicate name of firm or entity that prepared each submittal on label or title block.

Provide a space on label or beside title block to record Contractor's review and approval markings and action taken by CO.

Include the following information on label for processing and recording action taken:

Project name.

Date.

Name and address of Contractor.

Name of manufacturer.

Unique identifier, including revision number.

Number and title of appropriate Specification Section.

Drawing number and detail references, as appropriate.

If more than one item is shown on submittal sheet, identify item.

Deviations: Highlight, encircle, or otherwise identify deviations from the Contract Documents on submittals.

Additional Copies: Unless additional copies are required for final submittal, and unless CO observes noncompliance with provisions of the Contract Documents, initial submittal may serve as final submittal.

Use for Construction: Use only final submittals with mark indicating action taken by CO in connection with construction.

MEASUREMENT AND PAYMENT

No separate measurement and/or payment will be made for this section. Payment shall be included with work shown in the schedule of items.

PRODUCTS
