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.
On November 16, 2021 the City Council approved Change Order #1 granting an additional 190 days to the contract due to delays encountered with coordinating relocation of the cell phone carrier transmitters on the tower.
On February 2, 2022 the Chief Procurement Officer approved Change Order #2 to add $2,470 of contingency for additional materials.
On May 13, 2022 the City Manager approved Change Order #3 to add $13,530.40 of contingency to support changes to the pre-cast panel material.
On June 8, 2022 the City Council approved Change Order #4 granting an additional 140 days to the contract due to supply chain delays with needed pre-cast materials.
On June 17, 2022 the City Manager approved Change Order #5 to add $30,199 of contingency to pay for scaffolding design and implementation in support of the cell phone carrier relocations, changes to light pole removals, and modified pier foundation design.
On July 13, 2022 the Chief Procurement Officer approved Change Order #6 to add $5,676 of contingency to pay for additional concrete overlay and transitions for two areas on Entry Level 1 within the tower.
On September 9, 2022 the City Manager approved Change Order #7 for an additional $3,910 of contingency to permit a material change for the interior concrete flooring finish and associated additional labor required to install the new material.
The contract completion date for the project was September 30, 2022.
DISCUSSION:
This change order requests additional dollars to pay for a 20-year extended warranty on the waterproof membrane system installed around the exterior base of the structure. The product included a 5-year warranty as standard. The product is Monolithic Membrane 6125-FR by Hydrotech. The product was tested and approved as watertight by International Leak Detection LLC as reported in their EFVM Test Report.
Contract work was not completed before the winter season. Outstanding landscaping items cannot be installed at this time. This change order requests an extension of 244 days for a revised contract completion date of June 1, 2023.
The amount of this change order, inclusive of all previously approved changes, exceeds the original contract amount by $59,235.40 with a total of 574 additional days.
This contract was approved with a contingency in the amount of 3% ($62,764.56) of the original contract value and 29 days. Staff requests the use of contingency funds for the change order. Due to the increase in construction days, City Council approval is required. A summary of the award and contingency information is provided in the tables below.
