Report
Summary
The PVC-Lined Concrete Sewer Condition Assessment Report dated April 2017 recommended rehabilitation of 71 sewer pipe segments totaling approximately 44,000 feet (8.3 miles) at various City locations and rehabilitation of 190 manholes. Sewer pipeline rehabilitation may include spot repairs of PVC lining or cured-in-place pipe (CIPP) lining pipe segments manhole to manhole. Manhole rehabilitation may include coating restoration, lining repair, structural inserts or replacement. In addition, complex wastewater bypass systems will be required to complete some of the work.
B&F Contracting, Inc.'s initial contract services will include preparation of a Guaranteed Maximum Price (GMP) proposal for the construction services provided under the contract and participating with the City in a process to achieve the local and Small Business Enterprise (SBE) goal of 2 percent that was set for the project. B&F Contracting, Inc. will be required to solicit bids from prequalified subcontractors and to perform the work using the City's subcontractor selection process. B&F Contracting, Inc. may also compete to self-perform limited amounts of work.
B&F Contracting, Inc. will then assume the risk of delivering the project through the GMP. The construction services include, but are not limited to: bidding, awarding and managing subcontractors; preparing necessary GMP proposals; and implementing the rehabilitation solutions determined under the pre-construction phase.
Procurement Information
