EVALUATION FACTORS

BID EVALUATION FACTORS.

The following criteria are for bidding purposes:

a. The dredge will remove an estimated 1,200,000 cubic yards (917,500 cubic meters) of sediments from the Ohio River channel and associated tributaries. The sediments consist of primarily medium to coarse-grained sands with a d50 of 0.03 inch (0.8 mm).

Laboratory analysis of the sediment samples taken from the project area indicate an average sediment dry unit weight of 126 lb/ft3 (2.019 g/cc). This measurement indicates 34.50 percent voids, based on the assumption of a 165 lb/ft3 (2.65 g/cc) particle density for sand. In the saturated state, such as sediments on the bottom of the project area, the void space is filled with fresh water, resulting in a saturated sediment density of approximately 141 lb/ft3 (2.257 g/cc).

The dredge efficiencies for this project are given in Table I and depend on the dredge configuration.

TABLE I – DREDGE EFFICIENCIES

Dredge with walking spud De = 0.50 Dredge with spud carriage De = 0.75

Bank height efficiencies are listed in Table II for various dredge sizes.

TABLE II-BANK HEIGHT EFFICIENCIES

20-inch (508-millimeter) Dredge Be = 0.80 22-inch (559-millimeter) Dredge Be = 0.75 24-inch (610-millimeter) Dredge Be = 0.71

The production calculation is to be based on the capability of the dredge plant to pump a 78 lb/ft3 (1.25 g/cc) slurry at the point in the dredging cycle in which the cutterhead is engaging sufficient bank height for loading the pipeline with slurry. The dredge production will be calculated in volumetric production (cubic yards), with the calculations based on the saturated sediment density. The carrier water has an assumed water density of 62.4 lb/ft3 (1.0g/cc). The pump head reduction coefficient (K) is assumed to be 0.24. The dredge production is calculated by the following equation:

PRODUCTION (CUBIC YARD/HR) = C * Q * 133.33 * De * Be with C, or [CUBIC METER/HR = C * Q * 3600 *De * Be] the percent by volume of in situ material in the flow, defined by the following equation:

with, pm - pw C = ------pI – pw pm = The specified slurry density of 78 lb/ft3 (1.25 g/cc) pw = The specified carrier water density of 62.4 lb/ft3 (1.0 g/cc) pI = The specified saturated sediment density of 141 lb/ft3 (2.257 g/cc) and, Q = The discharge flowrate ft3/s, (m3/s) See Appendix B for procedure to determine Q

133.33 = A conversion factor from ft3/s to yd3/hr 3600 = A conversion factor from second to hour De = The stated dredge efficiency of the dredge plant Be = The stated bank height efficiency for the dredge size

The dredge must be capable of picking up and transporting the sediment to disposal within the limitations imposed by conditions of pump cavitation and available horsepower. Calculations used to support the bid production shall be in accordance with this section and Appendix B, EVALUATION OF THE DREDGE PUMP at the end of Section 35 20 23 DREDGING.

b. The dredge will operate an equivalent of 18 hours each calendar day at the effective bid price.

c. The dredge will dredge to a depth of 33 feet (10.0 meters) below the water surface with a terminal elevation of 10 feet (3 meters) above the shore or water surface. Total pipeline length shall include the discharge line on the dredge, plus 2400 feet (731.5 meters) of pontoon discharge line, two (2) swivel elbows and all other associated connection fittings.

d. The information obtained from equipment schedule, production calculations, and pump and system curves for the dredge and plant.

The comparative total cost of each bid received will be computed by adding the following cost elements:

(1) The lump sum cost of mobilization and demobilization of the dredge and attendant plant.

(2) The cost of operating the dredge and attendant plant.

a. Estimating effective pay time, to the nearest hour, will be determined by dividing 1,200,000 cubic yards (917,500 cubic meters) of sediment dredge production for conditions stated above and the Contractor’s corresponding guaranteed production rate.

b. Estimated non-effective pay time will be assumed to be 0.3 times (a) above.

c. The cost of operating the dredge and attendant plant will be computed by adding the products of:

1. Estimated effective pay time multiplied by the appropriate bid price per hour.

2. Estimated non-effective pay time multiplied by the appropriate bid price per hour.

(3) The cost of Mileage for Mobilization and Demobilization of dredge and attendant plant

a. The cost for travel by the dredge, from home port to first dredge site and from last dredge site to home port w i l l b e computed by multiplying an assumed total distance of 1 mile by the appropriate bid price per mile.

b. The cost of travel for the dredge while on Transit mileage between dredge sites, will be computed by multiplying an assumed total distance of 1 mile by the appropriate bid price per mile.

(4) The cost of operating On-Shore Disposal Equipment will be computed by adding the products of:

a. The lump sum cost of mobilization and demobilization of the On-Shore Disposal Equipment.

b. The estimated effective pay time multiplied by the appropriate bid price per hour.

c. Estimated non-effective pay time multiplied by the appropriated bid price per hour.

(5) The cost of operating Floating Pontoon Pipeline will be computed by adding the products of:

a. The lump sum cost of mobilization and demobilization of the Floating pontoon Pipeline.

b. Estimated effective pay multiplied by the appropriate bid price per hour.

c. Estimated non-effective pay time multiplied by the appropriate bid price per hour.

(6) Short term dredge events outside the normal dredge season bid items. A short term event normally does not exceed 10 calendar days at the one site.

GIVEN: d50 - Median particle diameter millimeters ρs - Particle density in lb/ft3, (g/cm3) ρi - Saturated density in lb/ft3, (g/cm3) ρm - Slurry density in lb/ft3, (g/cm3) ρw - Carrier water density in lb/ft3, (g/cm3)

DREDGE PUMP CHARACTERISTICS (Contractor Defined):

dd - Diameter of discharge pipes ft, (m) ds - Diameter of suction pipe ft, (m) ls - Length of suction pipe ft, (m) ld - Length of discharge pipe ft, (m) SPd - Maximum power rating of drive in HP, (J/s, W) RPMp - Maximum RPM of pump at SPd deye - Diameter of pump impeller eye ft, (m) dimp - Diameter of pump impeller ft, (m)

II. Procedure

Vscrit = FL × (2 × g × ds × (SGs - SGw))½ where

0.125

-6.9×d50

FL = (1.3 × Cvd ) × (1 - e ) g = Gravitational constant (32.2 ft/s2), or (9.81 m/s2)

SGm - SGw

Cvd = ------------------- Assume Cvd = Cvi

SGs - SGw

SGs = Particle specific gravity (lb/ft3 or g/cm3) SGm = Slurry specific gravity (lb/ft3 or g/cm3) SGw = Carrier water specific gravity (lb/ft3 or g/cm3)

Appendix B - ii

D × k Le = -------------

4 × C

Le = Equivalent pipe length of a fitting or bend ft, (m) D = Diameter of the pipe ft, (m) k = Loss coefficient (See Table 6.12, Ref. 5) C = 0.004 for pipe dia. > 20 in (50.8 cm)

The total equivalent pipe length for the suction and discharge fittings or bends are given below:

Lse = Σ Lsen

I=1 n

Lde = Σ Lden

Lse = Total equivalent pipe length for suction bends, entrance, or fittings ft, (m) Lde = Total equivalent pipe length for discharge bends, exit, or fittings ft, (m)

The total equivalent pipe length for the system is given as:

Ls = Lse + ls and Ld = Lde + ld where Ls = Total equivalent pipe for the suction side of the pump ft, (m) Ld = Total equivalent pipe for the discharge side of the pump ft, (m)

c. Determine cavitation limits of the pump:

In the absence of Net Positive Suction Head (NPSH) data for the pump, the cavitation limit will be expressed as a function of the impeller eye speed and diameter. The impeller eye speed should be between 40 and 44 feet/second, (12.192 and 13.411 m/s). The cavitation speed (RPMmax) of the pump is calculated as follows:

Veye × 60

RPMmax = -----------deye × π

Veye = Impeller eye speed in ft/s, (m/s) π = PI 60 = Conversion from seconds to minutes

Appendix B - iii

d. The diesel driven engine is essentially a constant torque machine which results in the power output being directly proportional to engine speed. As a result, the maximum diesel driven power available in order to avoid cavitation (SPmaxavail) is calculated according to the following in horsepower:

RPMmax

SPmaxavail = ------------- × SPd

RPMp

e. The Total Dynamic Head (HTDH) requirements for the system will be determined as indicated in the following equations ft, (m) of slurry:

π×ds

Qmin = ----- × Vscrit ds = diameter of suction pipe ft, (m) vscrit = critical suction velocity ft/s, (m/s)

Determine the minimum and incremental values of the flowrate (Q) and HTDH(units of slurry) by starting with the Vs equal to Vscrit and increasing the Vs in increments of hundreths of a ft/s by repeating paragraphs (e) and (f).

g. Determine the pump head reduction factor (RH) due to the solids effect in the pump as

The following is implied and should be calculated for all values of HTDH(units of slurry) in order to account for solids effect in pump:

HTDH(units of slurry)

HTDH(units of water) = ---------------------

(1 – RH)

j. Create a plot of HTDH(units of water) versus corresponding flowrates overlapping pump

Appendix B - v characteristic curves. This is the system curve. Determine an operating point, HTDH(units of water) , and flowrate (Q), and corresponding pump efficiency (Ep) in decimal format to the nearest thousandth from the system curve .

k. The Brake (Shaft) Power Required (SPreq) at an operating point is calculated as follows in horsepower or watts:

Q×HTDH(units of water) ×SGm Q×HTDH(units of water) ×SGm SPreq hp = ------------------------------- SPreq W = ------------------------------ × g

550 × 3960 ×(Ep - Re) 3960 ×(Ep - Re)

Q = flow rate ft3/s, (m3/s) HTDH= total dynamic head of water ft, (m) SGm = slurry specific gravity lb/ft3, (g/cm3) Ep = pump efficiency Re = pump efficiency reduction factor G = acceleration due to gravity 32.2 ft/s2, (9.81 m/s2)

l. In accordance with the governing affinity laws, the power demand of a centrifugal pump varies as the cube of the RPM.
