Base Bid included Wastewater and Electrical Improvements for Loops A, F and G with Aluminum conductor and Coated Manholes.
• Alternate A is a product alternate bid for uncoated manholes with a microbiological additive.This ended up being a cost savings of $32,780 when compared to the Base Bid of coated manholes for the amount of $316,300 and therefore, is recommended to be included.
• Alternate B is for the electrical improvements only for Loop B and is not recommended to be included as it would have exceeded the budgeted amount.
• Alternate C is a product alternate cost for the upgrade from aluminum conductor to copper conductor and is not recommended to be included as it would have exceeded the budgeted amount.
• Alternate D is for the addition of installing the cable in conduit in lieu of direct bury cabling and is recommended to be included due to long term maintenance and operations benefits.
These improvements provide for 5200 linear feet of 6" Wastewater Main, and Service connections for all pad sites in loops A, F and G; they also provide for Electrical system upgrades for Loops A, F & G including 20A, 30A and 50A, 120V receptacles at each Camp site. The proposed upgrades include replacing the existing transformers and distribution panels serving the campsites in order to accommodate increased load
Staff and project engineer, Freese and Nichols recommend that the Base bid in the amount of $2,337,167, Alternate A at a savings amount of -$32,780 and Alternate D in the amount of $253,872 for a total amount of $2,558,259 for this project be awarded to Gra-Tex Utilities.
