A roadway is being constructed and has a Subsoil Excavation Quantity of 835 CY, a
Regular Excavation Quantity of 250 CY and an embankment Quantity of 1040 CY.
Based upon this information, the Final Quantity to be paid for embankment will
be? - -- answer is---1875 CY
As items in the feild are completed,within 30 days, you will need to have the
supporting documentation available to support the pay item in the? - -- answer is-
--Plan Summary Boxes
Borrow Excavation is paid for as a? - -- answer is---Final Measurement
Conduit could be? - -- answer is---A) Open trench or Jack and Bore
B) Above ground and Bridge Mount
C) Bore under railroad
ALL OF THE ABOVE
Determine the adjusted plan quantity tonnage and the maximum tonnage that
can be paid for Miscllaneous Asphalt based on the current Specifications, which
allows a maximum pay of 105% of the adjusted plan quantity tons. ( pay to the
appropriate accuracy)
, Plan Quantity Area (SY) =700 SY ( no revisions)
Plan Quantity Tons: 70.0 Tons based on 2" thick per specs
Adjusted PQ Tonnage Placed =75.2 Tons from report
Gmm fromSpecs = 2.540 and Target Spread Rate =220 Lbs/SY
Gmm from Mix 1: 2.522 and tonnage- weighted Gmm=2.55 Lbs/SY - -- answer is---
69.5 Tons and max pay 73.0 Tons
Determine the final pay quantity for each project under one contract for the
following plan Quantity ietms, based on the current Specifications.
Project 1) Planned Quantity 3,000 LF, Planned errors = +98LF, Authorized change
amount =+25LF
Project 2)Planned Quantity 2000 LF, Planned errors = +300LF, Authorized change
amount = -45LF - -- answer is---Project 1) 3123 LF Project 2) 2255 LF
Determine the pay area (SY) and pay adjustment (SY) for Superpave Asphalt Base
(Pay Item 285) based on the information provided below. The maximum pay is not
to exceed 105%? - -- answer is---Planned Qty 40,000
Thickness 6" - two layers 3" each
spread rate 43.3 x 2.540 x 6= 600lbs SY = 300 LBS/SYper layer
avg weighted Gmm = 2580
Actual Tonnage = 13607.4
-- answer is-- = pay area= 40,595 SY Pay Adjustment +595 SY
