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.
Achen-Gardner Construction, LLC, 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; project planning and scheduling; construction phasing and scheduling that will minimize interruption to the City; alternate systems evaluation and constructability studies; advising the City on ways to gain efficiencies in project delivery; 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
Achen-Gardner Construction, LLC, 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.

It was mutually agreed that Achen-Gardner Construction, LLC, would be awarded the north project. The top three rankings follow:
Achen-Gardner Construction, LLC: Ranked #1
B&F Contracting, Inc.: Ranked #2
Sundt Construction, Inc.: Ranked #3
