Bid Tab.xlsx

This is a bid tabulation spreadsheet for the Bolton Pump Station Upgrades project, detailing cost estimates and contractor proposals for a wastewater infrastructure improvement initiative. The project encompasses ten line items including mobilization and demobilization, erosion and sediment control, bypassing operations, existing pump station demolition, pump station upgrades, force main investigation and connection, power system study, and asbestos survey and removal. The engineers' estimate for the complete project totaled $2,496,500, with bid responses received from five contractors: KG Contractors ($2,403,790), ORR Inc. ($3,194,500), HP Civil ($2,598,400), R.L. Reimers ($2,626,705), and one unnamed bidder. The significant line item is the Pump Station Upgrades, Complete (Item 5), ranging from $1,850,231 to $2,300,000 across the bids, representing approximately 74 to 72 percent of total project costs. Most bid items are quoted as lump sum (LS) contracts, with two items specified as fixed amount (F-A) contracts for the force main connection and asbestos removal and disposal.

The bid tab reflects competitive pricing variations across all line items, with KG Contractors submitting the lowest overall bid at $2,403,790, approximately $92,710 below the engineers' estimate. Bid prices ranged from a low of $2,403,790 to a high of $3,194,500, demonstrating substantial competition among qualified contractors. Individual line item pricing shows the most significant variance in the core pump station upgrades, with bids ranging from approximately 95 percent to 118 percent of the engineers' estimate for that critical component. The standardized connection and disposal items (Items 7 and 10) were uniformly quoted at $50,000 and $25,000 respectively across all bidders, suggesting established pricing for these specialized services.
