The methods of measurement and computations to be used to determine quantities of material furnished and work performed will be those generally recognized as conforming to good engineering practice.

2. Specific methods of measurement shall be as indicated in the specific Section for the Contract item.

3. Longitudinal measurements for surface area computations will be made along the surface

UNIT PRICE 01 22 00 - 3

(horizontally), and transverse measurements will be the surface measure shown on the plans or ordered in writing by the CM. Individual areas of obstructions with a surface area of 9 square feet or less will not be deducted from surface areas measured for payment.

4. Structures will be measured in accordance with the neat lines shown on the plans or as otherwise approved in writing.

5. Items that are measured by the linear foot will be measured parallel to the base or foundation upon which they are placed.

6. Allowance will not be made for surfaces placed over an area greater than that shown on the plans or for any material moved from outside the area of the cross-section and lines shown on the plans.

7. When standard manufactured items are specified, and are identified by weights or dimensions, such identification will be considered nominal. Unless more stringently controlled by tolerances in cited specifications, manufacturing tolerances established by the industries involved will be accepted.

B. Measurement by Weight

1. Materials that are measured or proportioned by weight shall be weighted on accurate scales as specified in this Section.

2. The Contractor shall have the weigh person perform the following:

a. Furnish a signed weigh ticket for each load that shows the date, load number, plant name, size and type of material, project number, schedule or purchase order number, and the weights specified herein.

b. Maintain sufficient documentation so that the accumulative tonnage and distribution of each lot of material, by Contract, can be readily identified.

c. Submit by the end of the next working day a summary of the number of loads and total weights for each type of material by Contract.

3. Trucks used to haul material shall be equipped with a cover suitable to protect the material and to protect the traveling public.

4. The truck tare to be used in the weighing operation shall be the weight of the empty truck determined with full tank(s) of fuel and the operator seated in the cab. The tare weight of trucks shall be recorded to the nearest 20 pounds. At the option of the Contractor, a new tare may be determined for each load. When a new tare is obtained for each load, the requirement for full tank(s) of fuel will be waived.

5. Net rail shipment weights may be used for pay quantities when evidenced by railroad bills of lading.

However, such weights will not be accepted for pay quantities of materials that subsequently pass through a stationary mixing plant.

6. Scales shall conform to the requirements for accuracy and sensitivity as set forth in the National

Institute of Standards and Technology Handbook No. 44 for Specification Tolerances and

Requirements for Commercial and Weighing Devices. Scales used in the weighing of materials paid for on a tonnage basis shall be approved and sealed in accordance with the requirements of the policies of the Bureau of Weights and Measures of the Department of Agriculture and Consumer Services, or other approved agencies, at least once every six months and upon being moved. Hopper and truck scales shall be serviced and tested by a scale service representative at least once every six months. Hopper scales shall be checked with a minimum 500 pounds of test weights and truck scales shall be checked with a

UNIT PRICE 01 22 00 - 4

minimum 20,000 pounds of test weights.

7. Copies of scale test reports shall be maintained on file at the scale location for at least 18 months, and copies of all scale service representative test reports shall be forwarded to VRE upon request.

8. The quantity of materials paid for on a tonnage basis shall be determined on scales equipped with an automatic printer. Truck scale printers shall print the net weight and either the gross or tare weight of each load. Hopper scale printers shall print the net weight of each load. The weigh ticket shall also show the legal gross weight for material weighed on truck scales and the legal net weight for material weighed on hopper scales.

9. If the automatic printer becomes inoperative, the weighing operation may continue for 48 hours provided satisfactory visual verification of weights can be made. The written permission of the VRE shall be required for the operation of scales after 48 hours.

10. If significant discrepancies are discovered in the printed weight, the ultimate weight for payment will be calculated on volume measurements of the materials in place and unit weights determined by the CM or by other methods deemed appropriate to protect the interests of VRE.

C. Measurement by Volume (e.g. Cubic Yard)

1. Material that is measured by the cubic yard, loose measurement or vehicular measurement, shall be hauled in approved vehicles and measured therein at the point of delivery. Material measured in vehicles, except streambed gravel, silt cleanout, or other self-consolidating material will be allowed at the rate of 2/3 the volume of the vehicle. The full volume of the vehicle will be allowed for streambed gravel. Such vehicles may be of any size or type acceptable to the Engineer provided the body is of such shape that the actual contents can be readily and accurately determined. Unless all approved vehicles are of uniform capacity, each vehicle shall bear a plainly legible identification mark indicating the specific approved capacity. Each vehicle shall be loaded to at least its water level capacity.

2. When approved by the CM in writing, material specified to be measured by the cubic yard may be weighed and such weights converted to cubic yards for payment purposes. Factors for conversion from weight to volume measurement will be determined by the CM and shall be agreed to by the Contractor before they are used.

D. Measurement by Lump Sum

If the Contractor believes that any plan quantity is incorrect, they may solicit, at their own expense, the aid of a Professional Engineer licensed to practice engineering in the State, Commonwealth, or District where the project is physically located to check the quantity or they may ask the CM in writing to check computations of the quantity. Written requests for a quantity check by the CM shall be accompanied by calculations, drawings, or other evidence indicating why the plan quantity is believed to be in error. If any item of the

Contract is found to be in error and so verified by the CM, payment will be made in accordance with the corrected plan quantity.

D. If the CM or VRE determines during construction that there is an error in the plan quantity, or that conditions vary from those anticipated in the design to the extent that an actual measurement of a plan quantity item is warranted, the CM will make such measurement and will notify the Contractor, in writing, of the rationale for adjustment. Payment will then be based on the measured quantity in lieu of the plan quantity.

Otherwise, except in an emergency endangering life or property, no extra Work or change shall be made unless in pursuance of a written Construction Change Directive or Change Order and no claim for an addition to the Contract

Amount or Contract Time shall be valid unless so ordered. If the Contractor believes a cost is associated with the supplemental instructions, the Contractor is to provide written notice to the CM within seven (7) consecutive calendar days of receipt of instructions.

CHANGE ORDER PROCEDURES 01 26 00 - 2

1.4 CHANGE ORDER PROCEDURES

A. Changes to the work can be by:

1. Change Order issued by VRE to the Contractor.

2. Contractor proposing a Potential Change Order (PCO) to VRE.

3. Time and Material as directed by the CM or VRE.

4. Specific requirements for a VRE ordered change or preparation and submission of a Contractor POC are detailed in the following subsections of this specification.

B. If any change causes an increase or decrease in the Contractor’s cost of, or time required for, the performance of any part of the Work under the Contract, the Contracting Officer shall make an equitable adjustment and amend the Contract in writing. Approval may be contingent on funding agency or VRE Board authorization.

VRE will issue a Contract Amendment all-inclusive of the terms of the Change Order(s) to the Contractor for signature. Once the Contract Amendment has been signed by the Contractor and VRE, it is considered executed.

1. VRE may require additional bond protection when a Contract price is increased. Such change will require notice to sureties and require that Performance and Payment Bonds be increased by the Contractor. The increase in protection shall generally equal one hundred percent (100%) of the increase in Contract price.

2. A copy of the revised Payment and Performance Bonds shall be provided by the Contractor to the

Purchasing and Contracts Office within 14 consecutive calendar days of VRE’s approval of such change.

The Contractor shall execute change orders with the consent of the surety or sureties on the Payment and

Performance Bond unless otherwise directed by the sureties. All such work shall be executed under the conditions of the original Contract, except that modification of the Time for Completion caused thereby shall be made at the time of approving such change.

project schedule. VRE may further issue a directive to proceed with additional work under Time and

Material basis.

B. The Contractor shall review any VRE requested or directed change and shall respond in writing within 14 consecutive calendar days after receipt of the proposed change stating the effect of the proposed change upon

Contractor’s work, including any increase or decrease in Contract time and price. The Contractor shall furnish

VRE an itemized breakdown of the quantities and prices used in computing the proposed change. The

Contractor shall also furnish any sketches, drawings, and/ or pictures to properly explain the change or impact to VRE. It is the sole responsibility of the Contractor to provide adequate change order backup to satisfy

VRE.

1. The value of any such extra work or change shall be proposed by VRE in one or more of the following ways: (a) by estimate in a lump sum; (b) by cost and fixed fee; (c) by unit price additions or deletions of quantities stated in the Contract; or (d) any other method permitted under VRE’s Procurement Manual.

2. If none of the aforementioned methods is agreed upon the Contractor shall proceed with the work without delay under Time and Materials, provided the Contractor receives a Construction Change Directive. In such case, the Contractor shall keep and present in such form as the CM may direct, a correct account of the cost, together with vouchers. The CM shall be permitted to verify such records on a daily basis and may require such additional records as are necessary to determine the cost of the change to the Work.

The CM shall include a firm Not-to-Exceed ceiling price that the Contractor may not exceed except at its own risk. A complete accounting of the extra cost shall be made within 14 consecutive calendar days after completion of the work involved in the claim. Refer to Time and Materials (Force Account) Change

Orders, below for a description of allowable costs when work is performed under force account.

C. Once the scope, cost and schedule impacts, if any, are agreed upon, the CM will prepare the Change Order, possibly combining with other approved Change Orders, and submit to VRE for Processing. Approval may be contingent on funding agency or VRE Board authorization. Once processed, a Contract Amendment will be issued for signature by the Contractor. Once the Contract Amendment has been signed by the Contractor and

VRE, it is considered executed. VRE may require additional bond protection as described above.

1.6 PREPARATION OF CONTRACTOR PROPOSED CHANGE ORDERS

A. The Contractor may propose a change by submitting a Potential Change Order (PCO) commonly known as

Request for Change (RFC) to the Construction Manager, describing the proposed change and its full effect on the Work, with a statement describing the reason for the change, the effect on the Contract Sum and Contract

Time with full documentation and a statement describing the effect on Work by separate or other contractors.

B. Contractor shall provide written notice of intent to claim additional cost or time within 14 consecutive calendar days of their knowledge of such. Failure to do so will result in automatic rejection of claims.

C. Submit a description of work that is considered beyond the scope of the contract for review and approval prior to start of work. VRE must be allowed sufficient time to review and make a determination of entitlement for additional compensation or time. The Contractor’s submittal shall be in sufficient detail to enable VRE to determine the basis of entitlement.

D. PCO must be signed and dated by the Contractor in order to be accepted by VRE.

E. Failure to furnish sufficient documentation or to qualify their reason for failure to do so may delay the project.

If such delay occurs, it will in no way relieve the Contractor of their obligation to meet the time limits or other requirements established for the contract or constitute basis for a delay claim on part of the Contractor.

CHANGE ORDER PROCEDURES 01 26 00 - 4

F. Maintain detailed records of related work performed, including photos if they help demonstrate the work.

Provide complete information required for evaluation of proposed changes and to substantiate costs of changes in the Work.

G. Document each quotation for a change in itemized cost or time with sufficient data to allow evaluation of the quotation.
