Summary
The purpose of this project is to replace the existing 15-inch sewer located on the west side of 59th Avenue with a new 24-inch sewer. The new sewer will start at the intersection of Dobbins and 59th Avenue, travel north on 59th Avenue approximately 4,700 feet, and will tie into the existing 24-inch sewer just before the Laveen Area Conveyance Channel crossing, approximately 950 feet south of Baseline Road.
Achen-Gardner will begin in an agency support role for CMAR Preconstruction Services. Achen-Gardner will assume the risk of delivering the project through a Guaranteed Maximum Price (GMP) agreement.
Achen-Gardner’s services include, but are not limited to: providing detailed cost estimating and identification of marketplace conditions; planning and scheduling project construction phases to minimize interruption to City operations; evaluating alternate systems; providing constructability studies; advising on potential efficiencies in project delivery; performing and initiating long-lead studies and procurements; and assisting in permitting processes. A Small Business Enterprise goal will be established for this project upon substantial completion of Preconstruction Services and prior to the start of construction.
