LS Clearing & Grubbing • 2. Steel (LS)and • 3. Optional Base (black option only).

  6. Automated Fuel Report in SM, Continues • Where to go and get this, and how does it work? • Link: http://infonet.dot.state.fl.us/tlconstruction/STARS.htm

  7. Prep & Doc Manual Continued • Ch 11 “Alternative Contracts” • Section 11.9.4 • Multi Layer Scenario • Single Layer Scenario

  8. What’s New?Review & Admin Manual • Chapter 4 “ Review Functions, Types & Certification of the F.E. Package” • Attachment 4-5 (Example PAR Letter) • Attachment Update

  9. Review & Admin Manual Continued… • Ch 9 “Roadway, Base, Stabilizing & Pavement Review” • Update

  10. Specifications….. What’s New • Piling: Clarification of Specs • 455 revised 7-2012 • Revised the F.E. Level II Training Course

  11. Specifications • Piling • Set Checks: Test Piles and Production Piles • 455 Spec Revised 7-2011 • Test Piles/ payment Issues

  15. Example (1) Test Pile (solution)Concrete Test Pile Authorized Length 140' Cutoff Elevation 25’ Splice Splice 25’ 30’ 0’ 140‘Test Pile 0’ Production Pile = 55’

  16. Other F.E. Issues • Plan Quantity Measurements • Designer Quantities • Only Errors/Field Revisions measured • Findings @ Districts /Process Reviews • Why Are we duplicating the work?

  17. What to Measure? Example On this Project, Designer missed a Turnout at Station 212+75.31 on the right side of the main roadway. The Pay Item Is Turnout Construction 286 -1 (a Plan Quantity Pay Item) This is a Plan Error, so how do we measure and document this?

  18. Work Example Using the information provided on the slide and the handout (Form 700-050-61) Please sketch the turnout with dimensions, Show date, time and person taking measurements /calculations. Calculate total Area to the nearest Square Yard. All dimensions are in linear feet.

  19. Work Example (Plan Quantity Error) Area of Trapezoid = [(a + b) ÷2]h = SF Area of Rectangle = ( b X c) = SF Area of Square = ( c X d) = SF Area of ¼ of Circle = (πr2 ÷ 4) = SF a = 24’ b = 28’ c = d = 12’ r = 12’ π= 3.1416

  20. What’s New…continued • Unpaid Bills • Building New Program System • User Friendly • Completed by 10/2012 approximately.

  21. FYI • Contractor Past Performance Rating (CPPR) in SIM’s • On Contracts Let After September 29, 2010. • http://webapp01.dot.state.fl.us/ContractInformationMonitoring/ContractorPastPerformanceRatingCategory2.aspx?CN=T1442&FP=42481615201&ITEM=1850 • Contact Lewis Harper • lewis.harper@dot.state.fl.us • Phone # (850) 414-4143

  22. How would you pay for the following? • Regular LS Projects, piling. • Are splices, driving the splice, redrives, etc. included in bid quantity? • If Not, how would you pay for these? • Is Turnout Construction (Asphalt) quantity included in lot for CPF?

  23. FINAL ESTIMATES ISSUES • Bituminous Adjustments • Reminder: • More than 365 days or 5000 Tons • Added Polymer PG 76-22 –Bit Adjusted began on Contracts Let January 2007 and forward and using Polymer Index for adjustment • Added AC Permeable Base, adjustment using AC index; for Contracts let July 2010 and forward, also for on-going projects.

  24. Bituminous Adjustments • What do we look for? • Contract Letting date • Correct Index Plugged in • How to spot check a certification/worksheet sheet • Hands on problem

  25. Bituminous AdjustmentsExample • Job let March 2009 • Asphalt certification April 2010 • Total Tons AC 3000 • Extra Gallons ARMI 350 • Total Tons Polymer 1500 • Total Tons AC Permeable Base 1200 • How to check for an accurate Worksheet or Certification?

  26. LS/DB Bituminous Adjustment Example

  27. This is one of the worksheet that the Contractor turned in

  28. How do we spot check?1. First check the Gallons2. Check to see if the Contractor used the correct Indexes and the price index difference. 3. Check the Total Monthly dollar amount

  29. Bituminous Example, continued….. • How to check to see if we have the correct gallons for AC and Polymer? • The formula for this is as follows: • 6.25 X Tons X 2000 # /Ton = Gallons 100 8.58 #/Gal • Or to simplify: you could use a short cut, for the liquid weight of 8.58 #/Gal, the constant will be 2.331 Gal/Ton • Tons X 2.331 X 6.25 = Gallons

  30. Bituminous Example, continued….. • 3000 Tons of AC and 350 Gallons of ARMI • The Contractor’s gallons =43,706 + 350= • 44056 Gallons Total AC • To check for correct Gallons AC = • 3000 Tons X 2.331 X 6.25 = 43,706 Tons, and • 43,706 + 350 = 44,056 Gallons …correct

  31. Bituminous Example, continued….. • The same goes for Polymer. • Tons X 2.331 X 6.25 = Gallons • 1500 X 2.331 X 6.25 = 21,853 Gallons, correct

  32. Bituminous Example, continued….. • For AC Permeable Base, the formula has a slight change. As follows: • Tons X 2.331 X 3 = Gallons • Here we multiply by 3 instead of 6.25 (per Specifications) • Gallons Permeable Base = 1200 X 2.331 X 3 = 8,392 Gallons, correct.

  33. Bituminous Example, Continued….. • Checking the Indexes: 2009 • (When Job was let) in March 2009 ; AC Price =1.6480 • Certification turned in- cut off April 2010; AC price= 2.1700 • Both are correct (Where do you go to check the indexes?) • http://www.dot.state.fl.us/construction/

  34. Fuel & Bit Index

  35. Fuel & Bit Index

  36. Bituminous Example, Continued….. • Next, check to see if the Price Index Difference is correct. How is this done? • Per Specs: 5% of index at time of bid is 0.0824 (1.6480 X 0.05 = 0.0824) • And 1.6480 + 0.0824 = 1.7304 see notes • April Index for AC is 2.1700 • Therefore the Price Index Difference for AC = 2.1700 – 1.7304= 0.4396 (this is correct)

  37. Bituminous Example, continued….. • The new total dollar amount is: • 44,056 X 0.4396 = $19,367.02 • The same calculations are applied to the polymer. • Same for permeable Base except for calculating the Gallons you multiply by 3 instead of 6.25. • See Hands on Work problem attached:

  38. Bituminous work problem # 1 This Conventional Project was let in March of 2011. You randomly picked out Contractor’s Worksheet No. 5 to check; period represents pay in Month of July 2012. You will need to check gallons, Total Gallons, Indexes (Current and Base), plus total dollar amount for AC, Polymer & AC Permeable Base.

  39. Index 2011

  40. Index 2012

  41. Bituminous work problem # 1

  42. Continue Problem # 1 • http://www.dot.state.fl.us/construction/fuel&bit/FuelForms.shtm • Go to the above link to get the latest form 700-050-66 on the Construction Website. • Fill out the form with the information provided in your handout (handout includes Contractor’s Certification). • Spot check this certification.

  43. Streamlining The F.E. Process • ALL FORMS SUBMITTED • Other Construction Forms • CPAM/PREP & DOC MANUAL • Combine/stand alone chapters • Example BEFORE/AFTER • Comp Book / Final As-Built Plans

  44. Streamline Contracts 2012

  45. Streamline Contracts • Goal of Streamline Contracts • Specifications • Final Estimates Process • Final Acceptance • DFEO Responsibilities - Closeout • Manual Write Ups

  46. Streamline Contracts • Goal of Streamline Contracts • Simplify Administration by selecting minor projects • (All jobs under $2,000,000 with less than 2,000 tons asphalt) • No change to plans • No reduction in Inspection

  47. Streamline Contracts • Specifications • Projects will be let as either LS or PQ • How do you know you have a Stream Line Contract? SCOPE OF WORK - INTENT AND SCOPE SP0040100SLLS SP0040100SLPQ

  48. Streamline Contracts • Specifications …continued MEASUREMENT AND PAYMENT SP0090103SLLS SP0090103SLPQ

  49. Streamline Contracts • Specifications ….continued • Pay adjustments; VERY LIMITED • Lump Sum – overbuild and foundations 1. Prices provided in Contract - Tables 9-2 and 9-3 2. Adjustments could be < or > the Contract amount; up to 105% of the original Contract amount. • Examples provided in the Prep & Doc Manual

  50. Streamline Contracts • Specifications ….continued • Pay adjustments; VERY LIMITED • Lump Sum – overbuild and foundations Continued…. 3. Failed Material: Remove/replace or leave in at no pay (FDOT discretion) • For failures other than items listed in Section 9-2 on Lump Sum Projects; use the unit price as determined by using the six month State Wide Pay Item Averages. • The dates will be the six monthsprior to the Letting Date • This will eliminate the need, in most cases, to process a SA/WO
