BACKGROUND:
On June 1, 2021 the City Council awarded Contract 21-149, Moser Tower and Eagle Street Pedestrian Walkway Rehabilitation, to StruxC-MC, LLC. Work on Moser Tower includes concrete repairs, addressing corroded steel surfaces, painting all the steel and replacing the staircase inside the tower. The Eagle Street walkway includes removal and replacement of a failing deck beam and the associated railing work.
DISCUSSION:
The contract documents called for all work to be substantially completed by November 5, 2021. At the beginning of the project, staff and the contractor discovered that workers could not be in front of the eight cell phone transmitters during construction, due to exposure to radio frequency waves. The solution was temporary transmitters to be installed on the outside of the scaffolding so the workers would not be in the path of the transmissions. Additional scaffolding design was needed and construction coordination with the cell phone carriers to install, and later take down, the temporary transmitters. This resulted in an approximate one-and-a-half-month delay.
The new schedule now has the work being completed at the end of the 2021 calendar year. Completion at the end of the year presents problems since some of the work items, such as installation of the waterproofing of the plaza and the landscaping, are not conducive to being done during colder temperatures.
To allow enough time in the spring of 2022 for the contractor to complete the waterproofing and landscaping, staff is recommending an extension of 190 days to the contract. This extension will make the new completion date May 14, 2022.
