Important Information (this text is hidden):

1- Tracking changes – Microsoft Word has problems merging document in which track changes is turned on or where it has been on and the changes have not all been accepted. Before merging any documents make sure track changes is off and all changes have been accepted.

a. Ctrl+shift+E toggles “Track Changes” also you can toggle them through the menu pulldown “Tools – Track Changes”. When you toggle them the “Reviewing” toolbar is activated and which allows you to see and accept or reject changes.

2- When creating or editing specs, do not type notes or comments in or before the “PART-1 GENERAL” line. These may cause problems in specs reading in correctly.

a. Do not worry about those written by Masterspec. We know how to ignore them.

b. You can write all you want throughout the rest of the Spec, including loading up the end of the spec if you would like.

3- Contracting:

a. We try to save this first sheet for whatever contracting would like to add.

b. The header is also left blank for contracting. Edit the header anywhere and it will affect the header throughout this document. The footer is ours.

4- Section C and other non-specs must be added manually (see 3.a above).

5- Adding specs requires updating the list of specs, this may be done automatically through the “Specs” toolbar “TableOfContents” and “Update TOC” Buttons.

6- Be consistent when creating specs. Using different formatting within a single spec causes confusion for Microsoft Word and it will mess up your formatting.

7- This is created using 12 point font. Reading in specs of other font sizes will create minor font inconsistencies. You can change the font size upon completion of the spec package manually to whatever size you want for consistency sake.

8- Other Regions can use this; it is a minor programming change to correct R4 to something else. Send a request and a faxed picture of a large Hawaiian pizza to me and I will get right on it.

SECTION 011250 - MEASUREMENT AND PAYMENT

PART 2 - GENERAL

2.1 SUMMARY

A. 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.

B. 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.

2.2 DETERMINATION OF QUANTITIES

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

1. 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.

2. 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.

3. 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.

4. 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.

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

6. 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.

B. 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."

2.3 UNITS OF MEASUREMENT

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

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

2. 50lb Bag: Measurement will be for the actual number of 50lb bags of standard bentonite grout.

3. 94lb Bag: Measurement will be for the actual number of 94lb bags of standard cement or grout.

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

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

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

c. 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.

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

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

a. Measured volume in container.

b. Metered volume by approved metering system.

c. Commercially package volume.

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

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

9. Lump Sum (LS): One complete unit.

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

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

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

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

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

2.4 METHOD OF MEASUREMENT

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

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

2. 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:

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

b. 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.

c. 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.

3. 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.

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

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