This project is part of the $24 Million contract called Package #4, which was designed by AECOM and awarded to Oscar Renda Contracting (ORC) in December of 2015. In January 2020, ORC mobilized to 17th NE and began construction of the sewer replacement. Most of the work was completed during winter and spring months under wet weather. They experienced a significant amount of ground water and saturated soils while performing the work. They continued to lay pipe and backfill during the wet months in attempt to maintain the schedule, but the material was too wet to meet the minimum compaction requirements specified by the contract. Upon completion of the sewer installation, ORC requested density tests in preparation for the asphalt overlay. The city contracts with Braun Intertec for all material testing on this project, and the construction inspector is responsible for arranging the lab technician to be onsite upon notification by the contractor. The tests were scheduled, and in June 2020, twelve compaction and moisture content tests were performed by the lab in different locations along the project. Only one of the twelve tests passed the compaction test, with eleven failing to meet the contract specifications due to high moisture content. Staff met with contractor and the engineer regarding the failed tests, and made clear that no final street resurfacing would be allowed until the trenches were reworked and compacted to meet the contract specifications. By this time, the utility crew had mobilized to another project, and before returning to 17th NE and MLK they needed to close up the other work area. From time to time, the contractor would return to fill in the trenches after traffic would dig them out; this has been an ongoing issue that can only be fixed once the mill and overlay is completed. They returned to MLK in August and installed trench blocks consisting of 2' sections of flowable fill material poured into strategic sections of the trench in an attempt to slow down the amout of ground water leaching from 20th NE. They then removed the wet material from the trenches, allowed it to dry out, and re -compacted the soil so as to meet the minimum requirements. STATUS OF ISSUE: On Saturday, September 19, 2020, the construction inspector notified city staff and the design engineer that all material has been reworked and that all trenches had passed the compaction and moisture content tests. They are now ready to install the final street repairs. The city street department has completed repairs to the road base in locations that are outside of contractor's work area. This will help prepare the entire street for the upcoming overlay. Both 17th and MLK will receive a full width asphalt resurfacing. The original plan was for 2" of mill and overlay, however staff is working with the engineer and contractor on an alternative for increasing the overlay thickness to 4" to improve longevity of the pavement. The contractor is scheduled to have the paving crew onsite on October 5th to begin the milling and overlay operations. The street resurfacing is anticipated for completion on October 10th. Staff has asked ORC to prioritize the street repair and to take any opportunity for an earlier paving operation should it be available. BUDGET: No impact. All repairs paid by the contractor. RECOMMENDATION: None. Discussion only.
