  2. LRE in a Nutshell • LRE produces conceptual estimates based on typical section characteristics applied to a length of roadway. The estimates contain pay items, quantities and unit prices that you can expect to have for the project characteristics described.

  3. VERSION VERSION SEQUENCE SEQUENCE SEQUENCE COMPONENT COMPONENT COMPONENT 4 LRE Project Levels PROJECT • Project Level: • Contains project identification information (Project number, District, County, Letting Date, etc.) • Pulls data from Financial Management system • Version Level: • Allows several versions of the same project (for alternate designs) • Project totals are at the Version level • There is always a designated Primary version • Component Level: • Relates to a design group of work on the project, or a pay item group (Earthwork, Roadway, Drainage, Signing, Signalization, Bridges, etc.) • Components are either required or optional, based on the model selected. Required components contain default characteristics. • Sequence Level: • Relates to typical section(s) on the project • 12 typical section models available, representing construction type, median and shoulder type • Default measurements & pay items describe assumed characteristics; these can be changed, as necessary.

  4. Typical Sections • 12 models are available in LRE, reflecting: • Construction type • New Construction • Resurfacing • Widening • Median • Divided • Undivided • Shoulder type • Rural • Urban • Default values representing typical section characteristics are pre-coded into the models. These values can be changed. New Construction, Divided, Urban Model

  5. Input & Calculated Quantities • For the “key” components, typical section quantities are based on formulas: • Earthwork • Roadway • Median • Shoulder • Characteristics areapplied to a lengthof roadway togenerate: • Pay items • Quantities • Unit prices

  6. Component Details • For certain components, default quantities are not formula-based; they are based on “average” conditions. • Default list of assumed pay items, quantities and unit prices (can be adjusted) (View) • Quantities are based on model selected, and: • Section Length (Drainage, Signing, Conventional Lighting, Erosion Control) • Type/size/description (Signalization, Retention Basins, Intersections)
