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 of pipe segments from 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., will begin in an agency support role for the design phase service and then hold the construction contract with the City for construction of the project. Services during the CMAR design phase include: reviewing design plans and specifications; developing cost models through detailed cost estimating and knowledge of marketplace conditions; advising the City on ways to gain efficiencies in project delivery; project planning and scheduling; construction phasing and scheduling that will minimize interruption to the City; alternate systems evaluation and constructability studies; long-lead procurement studies and initiating procurement of long-lead items; assisting in permitting processes; and protecting the owner’s sensitivity to quality, safety, and environmental factors. A small business enterprise goal will be established for this project prior to the start of construction.
Procurement Information
B&F Contracting, Inc., was chosen for this project using a qualifications-based selection process according to section 34-603 of the Arizona Revised Statutes (A.R.S.). Pursuant to A.R.S. title 34, the City is not to release the scoring of proposals until a contract has been awarded.
The PVC-lined concrete sewer pipe and manhole rehabilitation program was divided into north and south projects. Separate CMAR procurements were conducted for the projects. Contractors could submit for both projects; however, they could only be awarded one contract, not both. Achen-Gardner Construction, LLC, and B&F Contracting, Inc., ranked first and second, respectively, for both procurements. It was mutually agreed that B&F Contracting, Inc., would be awarded the south project. The top three rankings follow:
Achen-Gardner Construction, LLC: Ranked #1
B&F Contracting, Inc.: Ranked #2
Sundt Construction, Inc.: Ranked #3
Contract Term
The term for services is expected to be 30 months after issuance of the Notice to Proceed. Contract work scope identified and incorporated into the contract prior to the end of the contract term may be agreed to by the parties and work may extend past the termination of the contract. No additional contract work scope may be executed after the end of the contract term.
Financial Impact
B&F Contracting, Inc.'s fee will not exceed $300,000, including all subconsultant, subcontractor, and reimbursable costs.
