Alternate Bidding: The West Virginia Experience 2011Virginia Concrete Conference March 3, 2011 Richmond, VA Bob Long Executive Director ACPA Mid-Atlantic Chapter

Evolution of Alternate Design Alternate Bid (ADAB) Procedures  Joint efforts began in the Fall 2007 including WVDOH, FHWA and industry.  Formal procedures implemented in July 2008  All procedures finalized June 2010

CORRIDOR H – US 48 MOOREFIELD (July 2008)  First “formal” Alternate Bid pavement project  10.6 miles  4-lane arterial  No life cycle cost adjustment (C factor)  Included asphalt escalator  Asphalt by the ton and PCCP by the SY

CONCRETE PAVEMENT DESIGN Description:  Perpetual pavement design provided by Industry using Westergaard Equations Design  10” Jointed Plain Concrete Pavement on 4” free draining base  15’ doweled joints  Full depth tied concrete shoulders Assumptions: Analysis period = 50 yrs Initial performance period = 22 yrs Rehab performance period for CPR = 14 yrs Rehab performance period for Overlay = 14 yrs No Salvage year 50 Rehab #1 – diamond grinding and 7.5% joint patching Rehab #2 – overlay w/2” skid resistant mix w/PMA and 2% joint patching 10” Jointed Plain Concrete Pavement 4” Free Drain Base Pavement Typical

ASPHALT PAVEMENT DESIGN Description:  Perpetual pavement design provided by Industry using PerRoad 3.2 Design Program  13.5” HMA on 4” free draining base  Use PG polymer modified asphalt (PMA) binder in top 4.5” and on future overlays  Increase AC by 0.5% in bottom 5” Assumptions: Analysis period = 50 yrs Initial performance period w/PMA = 22 yrs Rehab performance period w/PMA = 14 yrs No salvage year 50 Rehab #1 – mill and resurface w/2” skid resistant mix w/PMA Rehab #2 – mill and resurface w/2” skid resistant mix w/PMA 2” 12.5mm skid w/76-22 AC 2.5” 19mm mix w/76-22 AC 4” 25mm mix w/64-22 AC 5” 37.5mm mix w/64-22 AC + 0.5% AC content 4” Free Drain Base Pavement Typical

The contractor shall construct one of the pavement systems as described herein and by the contract plans.

CONCRETE PAVEMENT SYSTEM: A concrete pavement system shall be constructed as defined by the concrete typical section(s) and all other documents referenced in the contract plans. This work and materials shall include jointed plain concrete pavement, free draining base, fabric for separation, subgrade, and subgrade preparation ASPHALT PAVEMENT SYSTEM: An asphalt pavement system shall be constructed as defined by the asphalt typical section(s) and all other documents referenced in the contract plans. This work and materials shall include asphalt wearing surface, asphalt base courses, free draining base, fabric for separation, subgrade, and subgrade preparation..

RECENT ADAB PROJECTS WV 10 – 3.7 miles l 4-lane arterial on new alignment – pre-graded l 10” PCCP vs ” Asphalt l Bid by the SY of Mainline Pavement l 4 of the 6 bidders bid concrete and the low concrete bid was 17% lower than asphalt l Low SY price was $60.00 King Coal US52 – 9.5 miles l Pre-graded and bid by the SY of Mainline Pavement l 10” PCCP vs. 11.5” Asphalt l 5 out of 6 bidders went concrete and the concrete bid was 3% lower than asphalt l Low SY price was $48.45

RECENT ADAB PROJECTS WV Corridor H, US 48 – 3.3 miles l 4-lane arterial on new alignment – pre-graded l 10” PCCP vs. 13.5” Asphalt l Bid by the SY of Mainline Pavement l 4 of the 5 bidders bid concrete and the low concrete bid was 29% lower than asphalt l Low SY price was $46.40

RECENT ADAB PROJECTS US Route 35, Putnam County – 14.5 miles l Design build – lump sum bid l 4-lane arterial with structures on new alignment – grade, drain, pave & structures l Bid by the SY of Mainline Pavement l 10” PCCP vs. 12.5” Asphalt l Four proposers – 3 confirmed use of concrete pavement l Successful team went with concrete

RECENT ADAB PROJECTS WV Corridor H, US 48 – 6.0 miles l Design bid build l 4-lane arterial with structures on new alignment – grade, drain, pave & structures l Bid by the SY of Mainline Pavement l 10” PCCP vs. 12.5” Asphalt l Low bidder went with concrete l Low SY price was $44.50

THE RESULTS  8 out of 9 projects went concrete when bid as an alternate to asphalt  On these projects about 80% of the bidders have bid concrete and all have had at least 4 bidders  WVDOH has saved $9,800,000 just on the four paving jobs alone over the low asphalt bids.

UPCOMING ADAB PROJECTS 1. Route 9 - Charlestown - VA line – 3.1 miles paving only 2. Corridor H - Rte. 1 to Mount Storm – 11.8 miles paving only 3. Corridor H - Mount Storm to Parsons - 10 miles grade, drain, & pave

Why ADAB “Works” in WV  WVDOH senior management support  Strong new construction program  Equivalent designs  Economized PCCP design (no seal, no dowels in shoulder, no cure on CTOGB  Most asphalt work controlled by one company

FALLOUT INTEREST  One new CPR projects is complete with 2 more about to come out  Concrete was bid as an alternate on an asphalt overlay job  The WV Turnpike is looking at concrete overlays instead of just asphalt  Extensive statewide concrete pavement training requested and delivered  Concrete is no longer a “four-letter word” – ACPA’s phone is ringing!
