Pay Item 104-11 Floating Turbidity Barrier: Underrun
Floating turbidity barrier was deployed to encompass the entire length of the work area. As this is a shallow
area with wide tidal fluctuation, sections of floating turbidity were replaced and paid for as necessary when
damaged or deteriorated. However, the turbidity barrier was well maintained and did not require as much
replacement as expected resulting in a 1 10 Linear Foot underrun of the pay item.
Pay Item 400-4-5 Class IV Substructure(Footers): Underrun
Class IV Substructure concrete was utilized and reinforced with rebar to retrofit and enlarge the existing
footers. In some instances, solid rock was encountered which reduced the depth of the concrete pour due to
existing conditions. Removal of existing solid rock may have undermined the existing footers. As such, this
pay item was underrun by 6.2 Cubic Yards.
Pay Item 400-4-5 Class IV(Concrete Encasements): Overrun
As added by Change Order#1, 1.6 Cubic Yards of Concrete was added to encase 6 of the 10 columns requiring
steel repair and coating at Piers 1 and 2. However, field conditions and concrete conditions of existing
encasements required replacement of all 10 encasements in lieu of the planned 6 encasements,resulting in the
4.1 Cubic Yard overrun. The Contractor's QC performed cylinder break testing of the last 3 encasements
poured.These 3 encasements totaling 1.3 Cubic Yards did not meet the strength requirements as set forth in
Section 346-3 of the FDOT Standard Specifications 2018 for Structural Class IV Concrete. However,due to
the fact that these encasements are intended for the protection of the steel column and not structural in nature,
it was recommended by the Senior Project Engineer to leave the encasement's in place at a reduced payment
price per specification 346-11.7, Calculating Pay Adjustments. This adjustment resulted in a line item
adjustment of-$510.28.
Pay Item 411-1 Epoxy Material for Crack Injection(Structures Rehab): Underrun
This line item relates to the material required to inject existing cracks within concrete structures. Existing
cracked concrete encasements were removed and replaced with new concrete.As a result,the line item quantity
for this line item was reduced by 4.00 Gallons.
Pay Item 411-2 Cracks Inject and Seal(Structures Rehab):Underrun
This line item relates to the length of existing cracks within concrete structures to be sealed and injected.
Existing cracked concrete encasements were removed and replaced with new concrete. As a result, the line
item quantity for this line item was reduced by 26 Linear Feet.
Pay Item 415-1-5 Reinforcing Steel—Bridge Substructure: Underrun
Class IV Substructure concrete was utilized and reinforced with rebar to retrofit and enlarge the existing
footers. In some instances, solid rock was encountered which reduced the depth of the concrete pour due to
existing conditions, Removal of existing solid rock may have undermined the existing footers. This field
adjustment resulted in the utilization of less rebar. As such, this pay item was underrun by 3,589 LBs of
reinforcing steel.
Pay Item 458-1-26 Bridge Deck Expansion Joint Rehab: Underrun
The planned quantity of expansion joint rehabilitation was 72 LF;however,the two measured expansion joints
totaled 42 LF resulting in an underrun of 30 LF.
Pay Item 470-1 Treated Structural Timber: Underrun
The planned quantity of structural timber was an estimated quantity; timber was ordered and installed
according to measured field quantities and cut to exact sizes resulting in a 3.7 MB underrun.

346-11.7 Calculating Pay Adjustments: The Engineer will determine payment
reductions for low strength concrete accepted by the Department and represented by either
cylinder or core strength test results below the specified minimum strength, in accordance with
the following:
F
Reduction in Pay is equal to the reduction in percentage of concrete cylinder
strength (specified minimum strength minus actual strength divided by specified minimum
strength).
For the elements that payments are based on the per foot basis,the Engineer will
adjust the price reduction from cubic yards basis to per foot basis,determine the total linear feet
of the elements that are affected by low strength concrete samples and apply the adjusted price
reduction accordingly.

346-12 Pay Reduction for Plastic Properties
A rejected load in accordance with 346-6.4 is defined as the entire quantity of concrete
contained within a single ready mix truck or other single delivery vehicle regardless of what
percentage of the load was placed. If concrete fails a plastic properties test and is thereby a
rejected load but its placement continues after completion of a plastic properties test having a
failing result,payment for the concrete will be reduced.
The pay reduction for cast-in-place concrete will be twice the certified invoice price per
cubic yard of the quantity of concrete in the rejected load.
The pay reduction for placing a rejected load of concrete into a precast product will be
applied to that percentage of the precast product that is composed of the concrete in the rejected
load. The percentage will be converted to a reduction factor which is a numerical value greater
than zero but not greater than one. The precast product payment reduction will be twice the
Contractor's billed price from the Producer for the precast product multiplied by the reduction
factor.
If the Engineer authorizes placement of the concrete,even though plastic properties
require rejection, there will be no pay reduction based on plastic properties failures; however,
any other pay reductions will apply.
