Where does BART sit ?
Imagine
  • Seat - DSS (Decision Support System)
  • The data tools support and sustain the groups
    activities
  • Legs - Activities
  • Bid history products
  • Collusion and Questionable activity detection
  • Market Analysis
  • Surface beneath the stool
  • Activities exist upon an uneven changing
    foundation.

The Seat
  • DSS (Decision Support System) database
  • Necessary on-going support activities
  • Data is checked, re-checked, then checked again
  • Examples of data verification
  • Project coordinates
  • Missing rejected contract bid tabs
  • Changing field definitions, i.e. spec changes,
    vendor ids
  • Update approved asphalt plant aggregate pit
    info
  • Vendor affiliate tracking
  • Pre-qualification
  • Asphalt / Aggregate inspections (QC) and approval
  • Use external sources i.e. ODNR, Associations,
    Contractors

FHWA / PR45 Reports
  • Two Quarterly Reports for the FHWA
  • Projects on the NHS
  • Firstly, a hardcopy report that provides
    information and s bid from the three lowest
    bidders for each project.
  • Secondly, a computerized Focus report that
    provides 1) split between pavement and bridge
    and 2) amounts associated with different
    concerned commodities for each project.
  • i.e. Asphalt, Excavation, Rein. Steel, Structural
    Concrete

2nd Leg
  • Collusion Questionable Activity Detection
  • Line Item Profiles (LIPs)
  • 80/20 Analysis
  • Asphalt Analysis

BART- TEA/TUG Daytona November 2005
18
Line Item Profiles
  • A Tool used to determine
  • Unbalanced Bids
  • Front- end Loading
  • Complementary Bidding
  • ODOTs current LIP method
  • Plotting bid line items
  • Any bidder whos bid amount (of each line item)
    is gt /- 1 of the total estimate of the project
  • Sham Bids
  • Inaccurate Estimates

80/20 Analysis
  • Collusion Pre-Test Where to look first
  • Technique
  • Analysis by contract work-type
  • Select items of work that have 80 of in
    work-type
  • Remove as-per-plan, lump sum, and each
  • Statistically standardize item price information
    (Price Change/Distribution Value)
  • Compare different items of work (apples to
    oranges)

BART- TEA/TUG Daytona November 2005
21
Blending Price Movement with Bidding Behavior
  • Compare the nature of the median price change by
    year.
  • Red flag items with too much price change from
    year to year for a given price range.

Method not effective for items with each, lump
sum or other hard-to-measure units.
BART- TEA/TUG Daytona November 2005
22
Asphalt Analysis
  • Track ownership changes from 2000 to present
  • Record mergers and acquisitions among paving
    firms
  • Changes in bidding behavior
  • Ownership of approved asphalt mfg. facilities
  • Ownership of approved aggregates sources
  • Search for collusion or other questionable
    behavior
  • Follow Info Tech methodology

  • Market Analysis
  • ODOT Cost Index Basket of Goods Approach
  • Asphalt Bundling Project
  • OTC Bid Analysis

BART- TEA/TUG Daytona November 2005
28
Asphalt Project Bundling
  • Scenario A single owner gains market control of
    Aggregate and/or Asphalt in a specific area
  • Strategy promote more than a single bid
  • Bundle (combine) similar Asphalt Projects in and
    around the market controlled area
  • Locate projects to bundle near competitive
    companies asphalt facilities
  • Select projects in areas with different bidders
  • Cross boundaries i.e. district, county
  • Increase size of project by value and/or
    quantity for economies of scale

Ohio DOT Cost Index
  • Primary Question
  • How will inflation and market fluctuations affect
    future construction costs?
  • Develop an Index (FY01-FY05)
  • Used bid data in DSS for analysis to create
    Laspeyres type index like Consumer Price Index
  • Selected largest expenditure items for each
    commodity
  • Basket of Goods Approach
  • Determined composite index for each commodity
    Basket
  • Developed an overall ODOT composite cost index of
    all the individual commodity indices

Ohio Turnpike Commission - OTC
  • OTC
  • The OTC separate from ODOT (similar operations)
  • The Commission manages 241-mile toll road
    spanning Northern Ohio
  • Project
  • Analyze each bid item within each OTC 3-lane
    widening project
  • To include all projects, bids, and items

(Contd) Ohio Turnpike Commission - OTC
  • BART
  • Current work
  • Develop an item master of all OTC related items
