Required NDT length shall be computed. The length of weld to be tested and the base metal, 1” either side of the weld, shall be cleaned of all rust prior to the testing. On cover plates with square ends, the weld shall be tested 1” from each corner along the ends of the cover plate plus 6” back along the side from each corner of the plate. On cover plates with tapered ends, the weld shall be tested along the end of cover plate, along tapered edges and 6” back along cover plate from end of taper. | ||
In the rare case that there are bottom flange cover plates, it is the responsibility of the SPM or SLE to coordinate with district bridge engineer or review visual records and field inspection notes and decide if these plates need to be tested. This should include only welded cover plate ends that terminate in a tension zone. If cover plates terminate at the inflection point or past it, there is a small chance that the bottom flange cover plate welds would need to be tested. (Rarely, other areas of cover plate welds could be tested based on deteriorated conditions as reported from the field on the Structural Rehabilitation Checklist.) | In the rare case that there are bottom flange cover plates, it is the responsibility of the SPM or SLE to coordinate with district bridge engineer or review visual records and field inspection notes and decide if these plates need to be tested.

751.6.1 Index of Quantities
The following list of pay items shall be used as a guide when preparing the Table of Estimated Quantities to be shown on the bridge plans. The pay items shall be listed on the plans in numerical order according to the Item Number. The Item Number is for information only and is not to be listed in the Table of Estimated Quantities. For pay items not listed, see the Preliminary and Review Section.
Accuracy and Rounding
When performing multi-step calculations as in the case of computing the final estimated quantities, keep at least one more significant digit in the intermediate result than needed in the final answer, in this case the final estimated quantity. Hence, the accuracy given in the following indexed table of quantities represents the plan reporting accountability to which the final estimated quantity is subject to for measurement and payment.
Round final calculation to the nearest unit increment given as the plan reporting accuracy and show on plans. Rounding should follow generally accepted rules and be agreeable to those responsible for estimating the final estimated quantities.

In order to satisfy funding requirements on projects that add capacity to the Interstate System, the quantities that are attributed to the addition of capacity shall be reported separately from the remaining quantities in the submitted computations. Quantities shall not be shown separately on the bridge plans.
751.6.2.1 Weight of Bolts and Shear Connectors
Refer to AISC Manual of Steel Construction or ASTM A325 for weight and dimensions of high strength bolts and washers. When calculating the weight of high strength bolts in structural connections, the following simplified weights may be used. These values include the weight of a regular hex head, one heavy hex nut, one washer, and the portion of the bolt projecting beyond the grip (washer thickness + nut thickness + 1/4“).
| Bolt Size Diameter (inch) |
Weight per 100 Bolts (pounds) |
|---|---|
| 5/8 | 40 |
| 3/4 | 65 |

| 1-3/8 | 352 |
| 1-1/2 | 400 |
| Weight In Place Per 100 Studs | ||||
|---|---|---|---|---|
| Stud Dia. | 4" | 5" | 6" | 7" |
| 3/4" | 63 | 75 | 88 | 100 |
| 7/8" | 81 | 98 | 115 | 132 |
751.6.2.2 Piles
Estimated quantities for piles, steel or concrete, shall be compiled as the entire length of the piles used, including the length of pile embedded in the pile cap or footing, measured to the nearest foot for each pile.
751.6.2.3 Pre-bore for Piling
Pre-bore is required when fill exceeds five feet as described in Sec 702 or when specified on the Design Layout. Pre-bore is also required through earth plugs. Pre-bore is computed as the length of pile measured from the bottom of the pile cap or footing to the natural ground line or as directed on the Design Layout rounded to the nearest foot for each hole.
751.6.2.4 Drilled Shafts
Drilled shafts, rock sockets and reinforcing steel quantity will be measured in accordance with Sec 701. Supplementary television camera inspection quantity will be calculated one for each drilled shaft. Foundation inspection hole quantities will be from the top of rock socket to 10 feet below the anticipated bottom of rock socket for each rock socket. Concrete coring quantities will be calculated for 10% of the drilled shafts for the total bridge through the drilled shaft and rock socket plus one foot below the bottom of the rock socket. Sonic logging testing shall be performed on all drilled shafts and rock sockets. Drilled shafts for high mast lighting will not require sonic logging testing and concrete coring.
751.6.2.5 Concrete
The volume of concrete shall be calculated to the nearest 0.1 cubic yard. Do not deduct for volume of concrete displaced by reinforcing steel or piling.
751.6.2.6 Polymer Concrete
The volume of polymer concrete shall be calculated to the nearest 1.0 cubic foot. Do not deduct for volume of concrete displaced by reinforcing steel.
751.6.2.7 Non-Destructive Testing (NDT) for Cover Plates
NDT shall be required for all top cover plates when a bridge is to be redecked. Required NDT length shall be computed. The length of weld to be tested and the base metal, 1” either side of the weld, shall be cleaned of all rust prior to the testing. On cover plates with square ends, the weld shall be tested 1” from each corner along the ends of the cover plate plus 6” back along the side from each corner of the plate. On cover plates with tapered ends, the weld shall be tested along the end of cover plate, along tapered edges and 6” back along cover plate from end of taper.
In the rare case that there are bottom flange cover plates, it is the responsibility of the SPM or SLE to coordinate with district bridge engineer or review visual records and field inspection notes and decide if these plates need to be tested. This should include only welded cover plate ends that terminate in a tension zone. If cover plates terminate at the inflection point or past it, there is a small chance that the bottom flange cover plate welds would need to be tested. (Rarely, other areas of cover plate welds could be tested based on deteriorated conditions as reported from the field on the Structural Rehabilitation Checklist.)
751.6.2.8 Temporary Shoring
When temporary shoring is required, it shall be reported as a lump sum item on the bridge plans.

751.6.2.14 Asphaltic Concrete Pavement
Seal coat or tack coat is required with the asphaltic concrete pavement. Unit weights will not be calculated.
751.6.2.15 Seal Coat
A seal coat shall be used when specified on the Bridge Memo. Grade B seal coats shall be used whenever a bridge deck is to receive an asphalt wearing surface. Grade A seal coats shall be used whenever the seal coat is to be the final riding surface. Unit weights will not be calculated.
751.6.2.16 Tack Coat
A tack coat shall be used when specified on the Bridge Memo. The following unit weights will be used to calculate the estimated quantity reported on the bridge plans.
- Tack Coat = 0.05 gal/sq. yd.
751.6.2.17 Excavation
Excavation shall be computed in accordance with Sec 206 and the limits shown in this section.
The Roadway and Drainage Excavation Line is the finish grade line after the bridge is completed in place. This may or may not correspond to the preliminary embankment line placed before the bridge is built.
The Excavation Datum is located at one foot above Low Water Elevation of the stream bed (round up to the next one foot). Use the low point of the streambed cross-section as Low Water Elevation, if a Low Water Elevation can not be found. Everything above this datum is Class 1 Excavation while everything below it is Class 2 Excavation.
Excavation Limit Rules
Soil or other sub-strata shall be excavated to the limits of:
- 18” around the perimeter at the bottom of footings, and vertically (*) to the finished Roadway and Drainage Excavation Line
- 18” for tapered wings only and around the wings on end bents
- No excavation below sidewalls or wings of a semi-deep abutment
- The perimeter of seal courses
- No excavation shall be figured for piles or bracing
- If there is less than 10 cubic yards of total excavation, no excavation item needs to be listed in the Estimated Quantities. See EPG 751.50 Standard Detailing Notes for the appropriate notes.
Classes of Excavation (**)
Class 1, Class 2 Excavations shall be computed in accordance with Sec 206 and the limits shown in the figures below. Excavation for structures below Excavation Datum Elevation will be paid for as Class 2 Excavation. Excavation for structures above Excavation Datum Elevation will be paid for as Class 1 Excavation. Use a minimum of 10 cubic yards of Class 1 Excavation when there is Class 2.
Class 4 Excavation shall be used for culverts. Class 4 Excavation shall be computed in accordance with Sec 206 and the limits shown below. Culvert concrete removal for extensions will be paid for as Partial Removal of Culvert-Bridge Concrete. See the Design Layout for special cases.
Cases of Excavation
Case 1 is when the ground line survey is a higher elevation than the roadway and drainage excavation line.
Case 2 is when the ground line survey is a lower elevation than the roadway and drainage excavation line.
(*) Soil shall be excavated vertically from the bottom of the footing for footing on pile, 6” above the bottom of the footing for footing on rock and 18” above the bottom of the footing for footing on shale.
(**) Use Excavation in Rock if it is anticipated to be more than 10 cu. yard. The designer should check with the Structural Project Manager before calculating the quantity of Excavation in Rock. See EPG 751.6.1 Index of Quantities Bridge.
