Continuing with System terminology… LRE is the Long Range Estimates System. This system produces a budget cost estimate before plans/quantities are available.
Expected
items and quantities are determined from the typical section(s) and length. Items, quantities, and prices are updated as the scope is refined and updated. Prices are based on the previous 12 months’ historical bid prices, and/or updated based on project conditions.

With a typical project, there are several common stages of development. In the Pre-Design stage, the project scope is loosely defined. Project limits and type of work are identified.
General Information
Timeline Pre-Design Design Letting & Bid Review Award Construction Using LRE, a Scope Estimate is produced. The project and scope estimate are entered into the 5 year work program- a system to schedule proposed work with expected funding.
28
Basis of Estimates- Part 1
Following the selection of a designer, the initial design and creation of plans begins.
Reviews are conducted at various phases, throughout the development of the PSE package.
General Information
Timeline Pre-Design Design Letting & Bid Review Award Construction During phase 1, basic plan and profile information is created. Complete requirements for each phase are shown in the PPM.
29
Basis of Estimates- Part 1
During phase II, additional details are defined- lighting, landscape, etc. Pay Items are identified at this time.
During phase III, most of the design work is completed. Quantities for all pay items are loaded into the Trnsport system. Specifications are under review, as needed.
General Information
Timeline Pre-Design Design Letting & Bid Review Award Construction Note: The LRE continues to be the primary source for project costs, until items, quantities, and prices are complete in Trnsport. It is important to maintain the LRE scope and details. 30
Basis of Estimates- Part 1
Sometime between phases III and IV, when the items and quantities are finalized, the LRE is archived, and the Trnsport estimate is used.
Where LRE contains
expected values
based on typical section and length, Trnsport contains
known values
based on calculation of quantities shown in the plans.

Most items of work call for the contractor to “furnish and install”, for a complete and accepted item of work.
Normal incidentals, i.e. hardware or coatings, are detailed in the standards or specifications.
When the designer calls for additional items of work to be included in an item of work, these incidentals generally increase bid prices. Significant changes should be addressed with separate or “special” payment.

Price decreases with increased quantity?
In general, larger quantities yield better unit prices, as the equipment and set-up costs associated with an item are distributed over a larger quantity. Unit prices stabilize when materials and labor become the significant factors.

The Trnsport CES module is an excellent tool for pricing items based on quantity. Regression models will provide price vs quantity graphs, as needed. These graphs are also helpful for identifying when price varies by district or market area. Unfortunately, the regression models only work when historical data is available.
