DATE: June 26, 2023
SUBJECT:
A Resolution authorizing Crawford, Murphy & Tilly to provide professional engineering services to the Water Production Division for a new water well construction project, in an amount not-to-exceed of $283,000.
PURPOSE:
To obtain City Council authorization to enter into an agreement for professional engineering services with Crawford, Murphy & Tilly (CMT), Aurora, IL for the design, bidding, and construction engineering of proposed Well 105 for the Water Production Division (WPD).
BACKGROUND:
Well 103, located at 501 Orchard Rd. (Ward 5) is a shallow well, constructed in 1988, and was capable of supplying approximately 700,000 gallons per day of raw groundwater to the City of Aurora Water Treatment Plant.
During recent scheduled well maintenance, it was discovered that the original construction of the Well 103 borehole had failed. A failure of the casing/well screen allowed massive quantities of gravel pack to collapse into the well, filling up approximately 35 feet from the bottom of the borehole. Although the well was operable at the time, significant expense would be incurred to reconstruct the well, and a loss of pumping capacity is projected to occur by Layne Christensen who assisted the city in the investigation. In addition, this well location is found in the 100 year floodplain and more specifically in the floodway. As a result, a new location has been identified for the proposed Well 105, at 2390 W. Illinois Avenue, the site of fire station #10 (Ward 5). Well 103 will be properly sealed per well abandonment regulations.
Benefits of the new well will be 1) constructed outside of the floodplain; 2) a larger capacity well is expected by drilling into a deeper rock formation; 3) the new well will have a much lower potential for contamination in the deeper rock formation.
DISCUSSION:
In order to drill a new well, ensure professional construction, and specify equipment selection, full design plans, drawings, and specifications must be developed and subsequently approved/permitted by the Illinois Environmental Protection Agency. CMT will provide comprehensive engineering services for the proposed Well 105 project.
CMT has been the engineer of record for the most recent well construction projects completed for the WPD including Well 28 in 2008 and wells 29 and 129, both in 2009, and several others in the 1990's. The proposed Well 105 is planned to be drilled and constructed in a very similar manner to Well 129. CMT possesses the appropriate expertise and qualifications for this project, as well as extensive project experience for the City of Aurora and long-term familiarity with the City of Aurora Water Production Division planning, operations, and assets, including the existing underground piping that will be connected to the new well. As such, it is recommended the agreement be approved per City of Aurora Code of Ordinances, Chapter 2, Division 2, Section 2-336 Contracts Exempt or Excluded From Formal Bidding: (a) The city may award a written contract for professional services, which shall include architectural, engineering, surveying, construction management, accounting, auditing, safety and security risk assessment, computer and data assessment and services, legal and other financial services, without complying with the other provisions of this division.
A proposal from CMT to perform the necessary design, project administration, and construction observation professional services is attached for a time and expense, not-to-exceed amount of $283,000. A budget transfer has been submitted to provide funding in the 2023 budget in account 510-4058-511-32-07.
IMPACT STATEMENT:
None.
RECOMMENDATIONS:
That a resolution authorizing Crawford, Murphy & Tilly to provide professional engineering services to the Water Production Division in an amount not-to-exceed of $283,000 be approved by the Mayor and City Council. It is further recommended that this matter be submitted to the Infrastructure and Technology Committee for review and recommendation.
