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.

751.6.2 Computation of 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 F3125 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“).

Weight of High Strength Bolts

Bolt Size Diameter (inch)	Weight per 100 Bolts (pounds)
5/8	40
3/4	65
7/8	95
1	135
1-1/8	180

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. Video 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, except where reported in the table of Estimated Quantities for Slab, where concrete is rounded to the nearest whole cubic yard (see EPG 751.50, Note B3.21). Do not deduct for volume of concrete displaced by reinforcing steel or HP piling. When CIP piles are used, the displaced concrete volume should be deducted.

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 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 or Temporary MSE Wall System

When temporary shoring or temporary MSE wall is required, it shall be reported as a lump sum item on the bridge plans. In addition, the estimated area of temporary shoring or temporary MSE wall shall be computed to the nearest square foot and recorded only in the quantity folder. Embedment of temporary shoring shall be taken as one third of the exposed height of the shoring for the purpose of estimating the shoring area. The bottom of temporary MSE wall shall be taken as the lower of the top of permanent wall levelling pad or bottom of improved foundation. For temporary shoring use 206-55.00 pay item and for temporary MSE wall system use 720-14.00 pay item (EPG 751.6.1 Index of Quantities).

751.6.2.9 MSE Retaining Walls

Quantities for Mechanically Stabilized Earth Wall Systems are to be calculated based on the vertical face of the wall system as shown on the plans. The payment for furnishing and fabricating the concrete facing elements, excavation and installing the leveling pad, furnishing, and installing the soil reinforcement, furnishing, and placing select granular backfill for structural systems, furnishing other incidentals related to the wall system, and erecting the wall system complete-in-place, will be considered completely covered by the contract unit price for Mechanically Stabilized Earth Wall Systems per square foot. The use of the Select Granular Backfill for Structural Systems pay item will not be required. For permanent MSE wall systems use 720-10.00 pay item (EPG 751.6.1 Index of Quantities).

751.6.2.10 Bridge Slabs

The gross area of concrete slabs is used in the Estimated Quantities table and shall be estimated to the nearest square yard longitudinally from end of slab to end of slab and transversely from out to out of the bridge slab. This shall include all expansion gaps within these limits.

The actual volume of concrete is used in the table of slab quantities for the purpose of preparing the cost estimate and is given on the plans as an aid to the contractor. The concrete on top of the backwall at end bents for expansion joint systems shall be included in this volume (see Note B1.7). Concrete shall be estimated to the nearest cubic yard instead of 0.1 cubic yard due to variances and assumptions used in this estimate (see Note B3.21). Reinforcing steel shall be estimated to the nearest 10 pounds.

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 cannot 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” around the wings on end bents
• 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.

Excavation Limits: Bridges

The following figures graphically show the excavation limits for various substructure types. The effects of skew on the fill slope (H:V) should be considered in determining excavation quantities at end bents.

H_θ = H/cosθ

Where:

H:V = horizontal:vertical components of fill slope (Normal)

H_θ = horizontal component of the fill slope parallel to centerline of roadway with V = 1

H = horizontal component of the fill slope normal to centerline of bent with V = 1

θ = end bent skew angle

Excavation Limits: Integral End Bent (Case I)

Excavation Limits: Stub Bent (Case I)

---

Excavation Limits: All Grade Separations

---

Excavation Limits: Stream Crossings (Typical)

---

Excavation Limits: Stream Crossings (No Excavation Item)

Excavation Limits: Retaining Walls

Note:

Excavation to be included in Estimated Quantity Table (Class 1 shall be calculated to the nearest 5 cubic yards).

Final limits of the roadway and bridge excavation to be coordinated with the bridge plans prior to estimating.

See EPG 751.50 Standard Detailing Notes for the appropriate notes.

Excavation Limits: Culverts

Excavation to be included in Estimated Quantity Table (Class 4 Excavation shall be carried to the nearest 5 cubic yards). Final limits of the roadway and bridge excavation to be coordinated with the bridge plans prior to estimating.

Excavation of 18" adjacent to the removal of culvert ends for purpose of extending the culvert will not be considered excavation and is considered part of removal. (Refer to Sec 206)

See EPG 751.50 Standard Detailing Notes for the appropriate notes.

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”).

MSEW Excavation and Fill Guidelines
Excavation	Std. Spec. Sec	Fill	Pay Item(s) on Roadway Plans 2B Quantities Sheet	Notes
Behind Wall	203	Compacted select granular backfill per Sec 720	Class A or Class C Excavation	• Show on roadway plans
Below Wall (Ground Improvement)	203, 214	Compacted rock fill or other per FIGR	Class A or Class C Excavation, Furnishing Rock Fill, Placing Rock Fill (or other fill per FIGR)	• Show on MSEW plans
Below Wall (Incidental)	720	Suitable material per District Geotechnical	NA	• Unanticipated and Unsuitable per engineer in field

Excavation Limits: Mechanically Stabilized Earth Walls (MSEW)

Excavation behind and below MSEWs are roadway pay items and based on information given in the Foundation Investigation Geotechnical Report (FIGR). Included may be a minimum soil reinforcement length, minimum embedment of the bottom of wall (top of leveling pad), global stability confirmation and angle of retained backfill which are used to estimate the excavation quantities. Use greatest of recommended minimum soil reinforcement length from

• FIGR, or
• the following table, or
• 8 ft. minimum.

One additional foot must be added to the selected length to determine estimated excavation quantities.

	MoDOT (USE)	Table 2-1 (FHWA NHI-10-024) (REFERENCE)
Case	Minimum Length of Soil Reinforcement, L	Minimum Length of Soil Reinforcement, L
Static loading with or without traffic surcharge	0.7H	0.7H
Sloping backfill surcharge	0.8H	0.8H
Seismic loading	0.95H	0.8H to 1.1H

Where,

H = Height of the wall as measured from the top of the leveling pad to the top of the wall

Note: Upper two layers of soil reinforcement shall be extended 3 feet to 5 feet beyond the lower layers for seismic requirement. (FHWA NHI-10-024 section 4.4.3)

Minimum soil reinforcement length shall be greater than or equal to as required for a stable feature wall for strong/stable rock as shown in following cases 5 through 7.

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 separate from the roadway and will have its own alignment where the wall earthwork can be quantified and shown independently in a table row.

Ex. 2 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.

General Section thru MSEW In Cut

In Cut: (Cases 1 to 6)

θ can equal ɸ_Ƅ 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.
