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.

All estimated quantities shall be carried to the degree of accuracy specified in the Index of Estimated Quantities. All quantities shall be listed on the plans in the order and worded exactly as shown in the Index of Estimated Quantities.

Two sets of quantity computations shall be independently performed and then agreed upon by the individuals performing the computations. Both sets of computations shall be bound together and submitted with the design plans.

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“).

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 the greater of either 10 feet or twice the diameter of the rock socket below the anticipated bottom of rock socket for each 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.

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

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 for pay and, if necessary for clarity, details can be shown on the plans (for example, to show unusual NDT locations not covered elsewhere). 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.

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 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.

Mechanically Stabilized Earth Walls (MSEW) Excavation and Fill

Excavation and Fill “behind” MSEW:

Excavation classes, quantities and pay items are determined and computed by districts for all MSEWs (Bridge Division walls and District Design Division walls) and are to be included on the roadway plans. Excavation before wall should be addressed same as excavation behind wall. Fill behind MSEWs is included in the cost of MSEWs and no separate quantity or pay item is required.

Excavation and Fill “below” MSEW (below top of leveling pad):

Excavation classes, quantities, replacement fill and pay items are determined and computed by districts for all MSEWs (Bridge Division walls and District Design Division walls) when required on the Foundation Investigation Geotechnical Report (FIGR), and are to be included on the roadway plans. When the FIGR gives excavation limits and type of replacement fill required for ground improvement, a detail is typically added to the MSEW plans showing the removal area and the removal locations along the wall (also referred to as “soil improvement”, “ground [or soil] mitigation”, “foundation replacement” or “foundation excavation”).

TABLE OF EARTH WORK EXCAVATION QUANTITIES EXAMPLE IN ACCORDANCE WITH DISTRICT PROCEDURE

The excavation table example provides for identifying both Bridge Division MSE walls and District Design MSE walls.

For District Design MSE walls:

Ex. 1 shows that a wall can be laid out along a roadway where it makes sense to include the wall earthwork with the roadway earthwork. This will be the case most of the time.

Ex. 2 shows that a wall can be laid out separate from the roadway and will have its own alignment where the wall earthwork can be quantified and shown independently in a table row.


General Section thru MSEW In Cut

In Cut: (Cases 1 to 6)

θ can equal ɸƄ for computing excavation quantities. It may also be 1:1 (H:V) or 2:1 (H:V) at discretion of district.

In Fill: (Case 7)

Excavation shall be computed based on the wall and soil (and/or rock) parameters as given in the FIGR. Dimensions of ground improvements will be given in FIGR if required. This includes area elevation, length and locations along the wall and slope cuts*.

Rock fill in accordance with Sec 214 is typically used as replacement fill for ground improvement.



Case 1: In cut with soil excavation (behind wall)
