-
The City received nine tightly competitive bids from most of the top US tunneling contractors, and a few internationals. All of the bids were below the Engineer's Estimate of about US$280 million, with the Shea/Kiewit JV submitting the apparent low bid of $180.2 million (Table 1).
-
All of the bids included a mandatory alternate for an Owner Controlled Insurance Program (OCIP) versus a Contractor Controlled Insurance Program (CCIP).
-
The contract scope includes the Deep Rock Tunnel Connector and the Southport Advanced Wastewater Treatment Facility Levee. The 8-mile (12.9km) long Deep Rock Tunnel Connector (DRTC) is the spine of the City's US$1.7 billion Long Term Control Plan to curb stormwater overflow of raw sewage into local rivers and streams, a project mandated under a Federal Consent Decree.
