DISCUSSION:
On October 5, 2021, the City Council awarded a Construction Contract to Doug Martin for the Fiscal Year ("FY") 2021-22 Slurry Seal Project ("Project") in the amount of $568,281.29. In addition, the City Council authorized the City Administrator to approve contract change orders for this project up to 10%, or $56,828.13. The scope of work for the Project entails the placement of approximately 1.66 million square feet of rubberized slurry sealant upon residential roadways in addition to removing and replacing approximately 1,000 square feet of damaged pavement, replacement of approximately 5,587 square feet of damaged sidewalk panels, replacement of damaged concrete curb and gutters, and replacement of all pavements striping and legends.
Change Order No.1 in the amount of $42,609.00 was authorized by the City Administrator since it was under his contract limit authority. Change Order No. 1 covered the cost for removal of 10 large tree roots that were discovered during the sidewalk replacements for the project. These Targe tree roots were very deep and were not anticipated during the design and bidding of the project. In addition, Change Order No.1 included milling and capping of 2,400 square feet of asphalt concrete pavement, where a sinkhole was discovered at the intersection of Bradford and Madison. This sinkhole was discovered after a severely rusted storm drain corrugated metal pipe collapsed under the heavy weight and vibrations caused by the steam rollers passing over the underground pipe.
Contract Change Order No. 2 is presented for Council consideration and approval and includes milling and capping of 5,655 square feet of existing roadway sections. The original bid included 1,000 square feet of full section pavement replacement; however, during construction it was determined that a 2 inch grind and overlay was a far better application to rehabilitate damaged sections of roadway area in lieu of a 1,000 square feet of full section pavement replacement. In addition, the contractor agreed to do this work utilizing the original bid pricing, which will be less expensive on a per square foot basis than the full section pavement replacement. Additional extraordinary repairs are included in Contract Change Order No. 2 which entails pavement restoration at the intersection of Madison and Bradford where a sinkhole developed due to a collapsed storm drain line and subsequent repair
FISCAL IMPACT:
The cost for Contract Change Order No. 2 amounts $74,152.30. The revised total construction contract amount is $685,042.59 and the total budget for this project amounts to $750,000. As such, sufficient funds exist for the recommended action.
