RE: Proposed Change Order No. 1
Contract No. GLWA-CS-277
Fourteen Mile Road PCCP Main Condition Assessment and Pilot
Study Evaluation
Vendor: Pure Technologies, Inc.
MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. GLWA-CS-277 Change Order No. 1 time extension “Fourteen Mile Road PCCP Main Condition Assessment and Pilot Study Evaluation” with Pure Technologies, Inc., at a cost not to exceed $2,277,315.00 for an increased duration of thirteen (13) months for a total contract duration of 31 months; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The GLWA has over 430 miles of prestressed concrete cylinder pipe (PCCP) pipe installed throughout the system. Recent catastrophic failures have occurred over the last few years include: (1) an 84-inch diameter transmission main near North Service Center, (2) a 48-inch diameter transmission main in Farmington Hills, and (3) a 48-inch diameter main in Livonia. The need to conduct evaluations of high consequence mains is clear. This innovative pilot test provides a condition assessment, evaluation, and long-term monitoring of a 9-mile length of the 14 Mile Road transmission main between the Franklin and Haggerty booster pump stations. This single main has no redundant looping and the proposed Haggerty Loop to connect the Eight Mile Road transmission main and the Haggerty booster pump station is still in the design stage with a multi-year construction period.
The purpose of this pilot study will be to develop a set of techniques that will contribute to the overall program to determine the best approach in evaluating the condition of PCCP mains within the system. The unique features of this program, that limit it to a single source are:
1. SmartBall - leak and air pocket detection tool
2. PipeDiver - electromagnetic inspection tool to detect broken prestressed wires within the PCCP mains. These broken wires are predecessors to the catastrophic nature of the PCCP main failure.
3. Soundprint - an acoustic fiber optic monitoring system to monitor for broken prestress wires after the PipeDiver evaluation.
All three of these technologies will be deployed in the transmission main under service. GLWA is unaware of any other technologies or vendors that can complete the objectives of the study while maintaining the transmission main in service.
JUSTIFICATION
The cost of repair after the 14 Mile Road break was approximately one million dollars. This direct cost does not include the indirect costs to businesses for the loss of water during the emergency break and subsequent boil water advisories.
GLWA staff recommends that the Board approve this time only change order to the pilot study to provide additional time to review the SmartBall and PipeDiver data to consider the implications for monitoring with the acoustic fiber optic system.
