Prodect Description, The Edison Production Well #2A Rehabilitation Project was awarded to Peerless Midwest for $49,991.00 on November 27, 2018. The project entails the removal of the pump, a pre -cleaning video, cleaning, replacement, or refurbishment of pump parts, a post -cleaning video, and the installment of the rehabilitated pump in the clean well. fro ject d/ e & Timeline A meeting on December 14, 2018 was held at Peerless Midwest to review the pre - cleaning video and discuss next steps. After the review of the video, the removed pump parts were viewed in shop for a visual of the rehabilitation to be done. The condition of the carbon shaft (Figure 1) was irreplaceable, and needs to be replaced with a longer lasting stainless steel shaft. The shafting in this application was also oversized for the application. As such, the stainless steel shaft to replace the removed carbon shaft will have a lesser diameter. Increased funds are requested in addition to the $3,000.00 allowance. It was noted the condition of this well and pump are in poor as it has not been serviced in about 18 years. There are also unforeseen conditions that until the pump is pulled are not predictable. Change Order A change order totaling $13,149.00 is requested to cover the additional parts needed for rehabilitation of the pump and the stainless steel shaft replacement. This creates a 26% change to the original contract of $49,991.00. The new contract amount is $63,140.00. We deliver services that empower everyone to thrive!!
