Page 4 of 7 Exhibit B add a huge amount of cost and impact to property owners and neighbors. Narrow patches can be plated but not a full panel replacement. Finding: There is a place, like on older concrete streets where patching is appropriate and should be considered. On streets where full panel is required, there are options that alleviate the need to plate for cure time. Rapid set concrete, while higher in cost, is one option that will allow material placement and within a few hours has achieved design strength and traffic access is restored. There are those situations where the shortened closure timeframe far outweighs the additional material cost for the concrete type. Question 11: Section 3.03.2 Street Cuts and Restoration – Portland Cement Concrete (PCC) Pavements, the referenced DET 1601 & 1601A shows partial panel replacement, which would not be allowed on older concrete streets with the referenced larger panels, “excessively large panels?” Finding: There are some excessively large panels irrespective of age that would not be approved for trench size repairs. When a trench repair is approved, the referenced detail applies to partial panel replacement. An example of excessively large panels that may not be appropriate for trench cuts are located in intersections. The turning movement, loading, and volume impact the design criteria when cut, and full replacement is appropriate to maintain the design lifespan and investment in these areas. Even in panels where patching is approved, permittees may want to consider if the reinforcing detail are warranted versus a full panel replacement. The Utility Inspector has the authority to determine which concrete street panels are approved for patching and which panels require full replacement based on size, age or existing condition. Question 12: Section 3.03.2 Street Cuts and Restoration – Portland Cement Concrete (PCC) Pavements, regarding compaction testing, where does the inspector direct utilities to test, and where are the test to be sent? Finding: The Utility Inspector may require compaction testing at any time and location within the excavation area if CLSM is not used for backfill. In practical matters, the Inspector will communicate that testing is required and will direct where testing is to occur within the excavation area. The Inspector will attempt to provide advance notice to allow the coordination of contract testing services without disruption of the project as much as possible. There are some scenarios where short notice testing is deemed appropriate by the Inspector. Compaction test results may be sent directly to the Inspector or to the general utility coordination email at PWMUtilityPermits@eugene-or.gov along with the project location and permit number. Question 13: Section 3.03.2 Street Cuts and Restoration – Portland Cement Concrete (PCC) Pavements, is the length to width ratio of 1.5:1 for full reinforcement referring to each individual concrete panel? Finding: Full reinforcement of any individual panel is required when the length to width ratio exceeds 1.5:1.
