46 Preparatory Agency Actions Prior to Implementation of the Recommended Practice To optimize the benefits of implementing the Recommended Practice, initial preparatory work and internal review is recommended. 6.1 Identification of Agency Goals, Requirements, Constraints, and Opportunities Before implementing a new or revised alternative pipe system bidding practice, it is recommended that an agency identify the requirements, constraints, and opportunities associated with any new or revised system, and select a system that will most effectively meet the agency's goals.

47 Practice can be expanded to include an inventory database which would include the following items at a minimum, noting that many agency inventories may have additional items: • Functional classification: arterial, collector, local, and so forth • Roadway number • Drainage system type: culvert or storm sewer • Station of culvert inlet or station range for storm sewers • Pipe system ID • Installation date: month and year • Original DSL in years • Current estimated service life or achieved service life to failure • Failure causation mechanism(s) This inventory could also form the basis for an asset management system for drainage pipe systems to assist with establishing long term pipe replacement and rehabilitation budgets.
